Case study remedial writing programme

Case study remedial writing programme The purpose of this study programme is to determine if students from the elementary level of Hin Hua High School (Chinese Independent School) improved in their ability to write in English after having studied specifically developed curriculum. The 7-hour remedial programme is to be conducted once the academic department releases the final assessment grades. Fifteen students with the lowest score were selected using the criterion method to undergo the remedial programme. the importance of all six major aspects of writing measured in the English Test which comprises mainly punctuation, grammar and usage, sentence structure, strategy, organization, and style. It is believed by attending the remedial programme selected students would be able to show the ability to make and articulate judgments by taking position on an issue or problem. Besides sustaining a position by focusing on the topic throughout the writing. They are alson expected to develop a position by presenting support or evidence using specific details and make inferences based on support or evidence. Most importantly, they should be able to organize and present ideas in a logical way by logically grouping and sequencing ideas. Hence communicate clearly by using language effectively and by observing the conventions of standard written English INTRODUCTION As a language teacher, I often select writing tasks from language textbooks to help students improve their writing ability. Behaviorists, communicative, cognitive, and discourse theories could influence writing approaches in language textbooks. Each theoretical framework has provided us with a better understanding of the multiple dimensions and purposes of teaching writing. A review of the developments in writing pedagogy leads us to conclude that we could teach writing as a means to improve linguistic, rhetorical and communicative competence or as a discovery and cognitive process. The writing tasks that we select from language textbooks and assign to students could reflect one or some of these pedagogical purposes. As teachers, we need to question and understand the pedagogical assumptions of textbook writing tasks so that we can select tasks that will help our students become confident writers and independent thinkers. Primary students entering the secondary school level (high School) are challenged not only to learn new content in the disciplines but also to communicate this. A significant number of students will not have adequate academic literacy levels to be able to do this successfully (Jones and Bonanno, 1995 (1). Atlhough traditionally students were expected to develop academic literacy skills without any explicit teaching of these skills, schools now recognize the increasingly diverse backgrounds of their student populations and have put in place mechanisms for helping students develop their academic literacy. These have included the establishment of literacy and learning units as well as the requirement for school curricula to address the teaching of writing skills including communication skills. English Learning Centre of Hin Hua High School Klang, like other literacy and learning units, has been involved in a number of collaborative projects with teachers involved in teaching Junior One to integrate the teaching of communication skills into the curriculum (Webb et al, 1995, Taylor and Drury, 1996). These initiatives have resulted in the development of new teaching materials and approaches as well as new practices of assessment and feedback. However, as subject area curricula are being adapted to computer-based forms of learning, it is also necessary to consider how the teaching of communication skills can be integrated into these programs or how the teaching of communication skills can be contextualized within the learning of subject area knowledge. With the current demand for propheciuency in English Language great importance has been given to developing programs to instill good writing modes to the elementary learners which aims to help students become successful editors of their own writing. 1.1 LITERATURE REVIEW Writing skills have been identified as to improve students thinking. Moffett and a few others have developed cognitively sequenced curricula for elementary and secondary writing, college composition, when it is sequenced at all, tends to rely on structural or rhetorical arrangements, which are neither sequential nor cumulative. Progressions from word to sentence to paragraph to theme confuse quantitative with qualitative growth, while rhetorical sequences confront students with cognitive problems of different but equal complexity. In short, from a cognitive perspective, most writing instruction in higher education is consistent with that in secondary education: what Stephen Judy described as Advanced Hodgepodge in high school gives way to Arrogant Hodgepodge in college. A large and growing body of research, however, shows that cognitive development follows a hierarchical sequence of stages and suggests that a curriculum can be sequentially organized to promote cognitive development. Blooms Taxonomy of Educational Objectives provides some essential connections between the cognitive abilities we expect of college students and a curriculum that can stimulate those abilities Blooms Taxonomy is one solution to the cognitive hodgepodge of the writing curriculum. It allows us to sequence instruction and assignments in ways that speak directly to students developmental needs. From least to most complex, For writing instruction the taxonomy provides a flexible model of what happens cognitively in the learning process Bloom described a six stage sequence: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. (See Figure 1) Figure 1.0 The flow chart of Blooms Taxonomy At each new level, thought processes build on and encompass previous levels. Implicit in this structure is the assumption of an ascending scale of difficulty and comprehensiveness. Thinking at the comprehension level is more demanding than at the knowledge level; cognitive problems requiring synthesis or evaluation encompass all the preceding levels. A review of Blooms definitions for each taxonomic level suggests what such a cognitively-based writing course might entail. Although the focus of each level is cognitive, rhetorical issues of audience and purpose are equally appropriate and can be specified for any assignment. Most of all, the taxonomy allows us to contemplate the value and feasibility of a cognition-based curriculum in writing. Such a curriculum would reflect the hierarchical relations of the various thought processes and would help to control for cognitive complexity in writing and thinking about distorting natural discourse. In this form, writing or writing-intensive courses would systematically develop students thinking skills rather than leaving them to chance or, worse, blunting the writers still-developing ability to explore and express ideas. In short, a cognition-based curriculum ensures that students participate fully in using writing as a mode of learning. 2.0 INTENDED PURPOSE The remedial programme is targeted for the elementary learners who are in the process of upgrading their writing skills to the pre -intermediate level. A total of 15 students are selected from the age group of 13 years old based on the final semester examination results. The examination basically structured in accordance to the textbook currently used in the school curriculum ,New Opportunities (Pearson Longman-Cambridge). Basically the (Stiggins to highlight achievement differences between and among students to produce a , 1994). School systems might want to classify students in this way so that they can be enhance their competency level even further. The major reason for using a norm-referenced test (NRT) is to classify students. NRTs are designed on dependable rank order of students across a continuum of achievement from high achievers to low achievers be properly placed in remedial or gifted programs. These types of tests are also used to help teachers select students for differe nt ability level reading or mathematics instructional groups. As the selected students fall under the below average group in Paper 1(Writing Assessment) whereby there are two parts that the had to complete here: SECTION A Notes Expansion and SECTION B Continuous Writing (Choose one topic out of five given) From the academic analysis it was found that majority students failed in Section B where it consists of 25% of the total marks of 40% of the Writing paper. Thus they are required to attend a 7 hour remedial programme to improve their writing skills by at least 85%.

Thus these students are carefully selected using the criterion method to undergo the 7 hour remedial programme. In order to drill and motivate these students in the remedial programme an enriching lesson plan is formulated to create a positive outcome at the end of the the 7 hour remedial programme. The purposes for emphasizing writing skills are to produce who can comprehend teaching and learning in a positive mental attributes. There is a wide body of research suggesting that assessing students written performance is a valuable undertaking. Not only is an instructor able to help a students progress, but also the instructor can facilitate the learning process and the learning outcomes by being aware of student performance throughout the academic session. Purpose for teaching writing Writing for Language Practice Writing for Rhetorical Practice Writing for communication Writing as a Discovery and a Cognitive process Figure 2.0: The Purpose for Teaching Writing Undeniably, 3R skills are important and necessary in daily living. They are also needed to support the development of a knowledge-based economy. Recognizing these needs, the school has initiated and implemented programmes to identify students who have not mastered the 3Rs. These programmes are designed to specifically address and overcome the inability of students to master the 3Rs. This is in line with the essentialism which instills students with academic knowledge and character development. Among the programmes that have been implemented in schools are the Early Inter ­vention Reading and Writing Class, Basic Skills for Reading, Writing and Counting Programme and the Literacy and Numeracy Programme at Level One. 3.1 Sub-skills of Writing Besides drilling and enriching the remedial learners with the core writing skills , there are also exposed to the importance of sub-skills in their learning such as: I Manipulating the script of the language: handwriting, spelling and punctuation. II Expressing grammatical [syntactic and morphological] relationships at the sentence level III Expressing information or knowledge in writing: explicitly implicitly IV Enrichment of Vocabulary PART B 4.0 Objectives of the 7-hour remedial programme The main aim in introducing and implementing the remedial programme particularly in the aspect of writing skills is to mainly: to develop competencies in writing skills among learners to move from a teacher-centered didactic model to a student-centered constructivist model to acquire the ability to write in a more clear, concise and acceptable manner 5.0 Instructional Design : Using the ADDIE Model to Build Writing Competency Among Remedial Learners Table 2.0 ADDIEs Model 5.1 Framework The generic term for the five-phase instructional design model consisting of Analysis,Design,Development, Implementation, and Evaluation.   Each step has an outcome that feeds into the next step in the sequence.   There are probably over 100+ different variations of the generic ADDIE model. Instructional design aim for a learner -centered rather than a traditional teacher-centered approach to instruction, so that effective learning can take place. This means that every component of the instruction is governed by the learning outcomes, which have been determined after a thorough analysis of the learners needs. This phases sometimes overlap and can be interrelated; however they provide a dynamic, flexible guideline for developing effective and efficient instruction. Figure 3.0 Instructional Design: Using the ADDIE Model 5.2 ADDIES Theory The ADDIE instruction model for this desin is outlined by Smith and Ragan(1995) in their book entitiled Instructional design. The focus is n 5 points Analysis, Design, Development, Implementation and Evaluation. From this theory the analysis has proved that there was a need to conduct remedial programme for the elementary low scorers where an opportunty was given to learn and develop basic essay writing skills. 6.0 Remedial Education Programme In Malaysia, the importance of remedial education gained attention in the 1960s. Results of a pilot project in nine schools between 1967 and 1970 showed a need for remedial education, especially for pupils in rural areas. This paved the way for remedial education programmes in primary schools. The pioneers in the field attended a two-year intensive course on remedial education in the United Kingdom. Subsequently, a national series of seminars and workshops on remedial teaching were organized. With the exception of small schools or under-enrolled schools, every school is allocated one remedial education teacher. At the school level, a Remedial Education Committee is formed, comprising the headmaster, remedial education teacher, class teacher, subject teacher, resource centre coordinator, and other teachers as members. The introduction of a new curriculum for primary schools in 1983 implied a return to the basics in education. The ultimate goal was to ensure that no pupil is illiterate by the year 2000. The implementation of the remedial education programme for children in Primary 1-3 is to ensure that they master the 3Rs. Children who have been recommended for remedial education are required to attend remedial classes. As of 1999, 54,000 primary school children have undergone the intervention programme. In addition to improving and enhancing teacher development, the Malaysian government also works towards improving the curriculum at school to meet the changing needs of the economy. During the Fourth Malaysia Plan, the primary school curriculum was revised with the aim of providing and establishing a firm education in reading, writing, and arithmetic. This led to the development of a new curriculum emphasizing the 3Rs. Studies looking at the returns to education in Malaysia have found positive results in those who have had some form of formal education, thereby providing support to the government guidelines on the primary curriculum which emphasizes the acquisition of basic skills.Education in Malaysia , changing very rapidly responding to the emerging focus of lifelong learning; the growing emphasis on learning; as opposed to reaching and the development of the new delivery systems 6.1 The Educational, Philosophical and Psychological foundation Elementary education shall aim to develop the spiritual, moral, mental and physical capabilities of the child, provide him with experiences in the democratic way of life, and inculcate ideas and attitude necessary for enlightened, patriotic, upright and useful citizenship. To achieve these objectives, elementary education curriculum shall provide for the: inculcation of spiritual and civic values and the development of a good citizen based on an abiding faith in God and genuine love of country; training of the young citizen in his rights, duties and responsibilities in a democratic society for active participation, in a progressive and productive home and community life; development of basic understanding about Malaysian culture, the desirable tradition and virtues of our people as essential requisites in attaining national consciousness and solidarity; teaching of basic health knowledge and the formation of desirable health habits and practices; development of functional literacy in English as basic tools for further learning; and acquisition of fundamental knowledge, attitudes, habits, and skills in science, civics, culture, history, geography, mathematics, arts, and home economics and livelihood education and their intelligent application in appropriate life situations. The Elementary Basic Education Curriculum focuses on the tool learning areas for an adequate development of competencies for learning how to learn.    The goal of Instructional design is to support the cognitive processes that result in learning (McGriff). The expected outcome of instructional design is to provide knowledge and skills to people. The three major learning theories are Constructivism, Behaviorism, and Cognitive. Instructional Design is based on constructivist principles. Instructional design is associated with instructional systems development (Leshin et al, 1992). An Instructional System is the arrangement of resources and procedures to promote learning (Berger and Kam). 6.2 Programme Design: ADDIE Model ADDIE is a general-purpose model, which can be used to create instructional products and program design. ADDIE is the acronym for Analyze, Design, Develop, Implement and Evaluate and summarizes the five steps in the Instructional Design process. The instructional designer makes decisions critical to ensuring the effectiveness of the educational experience in each phase of the process. In accordance with the process improvement model, the five phases are a loop, with the improvement of learning outcomes as the goal. Dick and Carey and Kemp (Kemp, et .al, 1998) expanded the ADDIE Model into nine elements. The Dick and Carey Model uses a Reductionist approach in breaking instruction down into smaller segments targeting sub skills. The learner is required to master of sub skills, which are aggregated to achieve overall skill mastery and learned behavior. It provides a systematic approach to curriculum and program design. Teaching is essentially a philosophical endeavor and therefore educational activity can be conceived within the context of a philosophy or worldview. The curricukum refelects the art and craft of teaching. Educational technology can provide diversity of thinking regarding curriculum and instruction which would be curriculum theorizing. 6.2.1 Analysis Basically the nature of the students whom the remedial programme to be conducted are students who learn English Language as a second language. They are originally from Chinese speaking families with a minimum exposure to English Language. Due to the expectation of the school and the educational needs in adhering English as one of the core subjects in school these students are required to have in depth knowledge and skill in it. All of them have been educated in the Chinese primary school education system. Based on the final semester examination results 15 students are selected to undergo remedial programme as they fall in the border line cases .The students acquire poor writing skills, while being able to construct sentences fairly well, they seem to have great difficulty in organizing and developing their ideas into the form of an essay that has an introduction, body and conclusion. In order to promote these students to the next level that is the pre-intermediate phase from their origin elementary level the English Language Department found it vital for them to attend a 7-hour remedial programme in order to find solution to this situation. All of them need to further develop their writing skills in term of cohesion and coherence; time and practice. 6.2.2 Design The main design goal for our programme would be on the cognitive strategies of being able to develop an idea for writing since all of them com e from a very similar background and have basic sentence writing skills. Besides the development of language in the mechanics of sentence construction such as syntax, grammar, structure, etc given priority. R.Gagne(1965) divided learning into 5 categories: Verbal or declarative knowledge, intellectual skills, cognitive strategies, attitudes and psychomotor skills. The learning goals are also in connection to these categories to try to put educational value behind our goals. At the same time the goal also reflects competences outlines by Benjamin Bloom (Bloom,1956). These include: Knowledge, Conprehension , Application, Analysis, Synthesis an Evaluation. These give our goals validity whereby competencies are incorporated in bringing about concrete task for learners that we assign in order to achieve their goals. Hence in the evaluation phase, we can use this aspect to find out the validity and the accomplishment of the learners in implementing the programme. Learning Goals and Type of Learning OBJECTIVE STANDARD GAGNES DOMAIN BLOOMS TAXANOMY Learners will identify an essay topic and 3 sub-topics Criteria established by Hin Hua High School, English Language Department Cognitive strategies Synthesis Learners will be able to write a 3 paragraph essay with an introduction, 2 sub topics to include their opinions, ideas and conclusion Criteria established by Hin Hua High School, English Language Department Declaration Knowledge Intellectual Skills Synthesis Evaluation Application Learners will be able to use the library and Handouts to research printed information on their topics Criteria established by Hin Hua High School, English Language Department Procedural knowledge (declaration knowledge) Knowledge Learners will be able to use proper mechanics of grammar syntax Criteria established by Hin Hua High School, English Language Department Intellectual Skills Application Learners will be able to present their topics in class Criteria established by Hin Hua High School, English Language Department Declaration knowledge Comprehension Table 3.0 Learning Goals and Type of Learning 6.2.3 Development In order to establish a approachable remedial programme for the elementary learners , we English teachers have developed a remedial programme which will undertake a 7 hour learning process. The teachers from the same level have brainstormed and come up with a course content for the 7-hour teaching and learning programme. The teachers from the same teaching level are the best person to create the lesson as they deal with the same competency level of students all the time and are considered experts in their area. Besides this, they will be able to make he printed and computer materials and added step of getting the right content for the level. On top of that since they have already been teaching in the same scope so they will be undoubtedly familiar in the process of teaching and guiding the learners in order to make the remedial programme a success. 6.2.3.(1) Procedure The remedial programme would be in the English medium since the main objective is to improve writing skills among elementary learners. The programme consists of 6 regular sessions and followed by a review and a test day. Each hour is scheduled to be conducted for 60 minutes ***Details on the whole programme given on Part D 6.2.4 Implementation Further to the development to the development the teachers would be equipped with intact course content for he programme. The module would be prepared in balance with the time frame allotted for the programme. Any teacher who is selected for this task should be ready to undertake the teaching process based on the scheme that has been prepared. Al l 15 students will be instructed to attend the programme for 7 hours. These are the various aspect of implementation emphasized in the learning process: Approaches Discovery and guided discovery- instructional techniques Observation-modeling examples by teachers Guided participation cooperation of teachers and learners in a task Strategy instruction Direct Explanation Self Instruction Training Dyadic Instruction Table 4.0 Learning Process Implementation 6.2.5 Evaluation The evaluation phase consists of two parts: formative and summative. Formative evaluation is present in each stage of the ADDIE process. Summative evaluation consists of tests designed for domain specific criterion-related referenced items and providing opportunities for feedback from the users. Primarily the evaluation is done in two parts. The first phase will be the evaluation of student work based on the objectives in the Learning goals and type of learning listed above. Students will be rated by their teacher based on the A,B,C,F criteria set by the English Department. An A is excellent work, B is average, and C will mean student needs improvement. An F would mean that student failed the writing assessment with below 60% of mark. Students will be evaluated at each stage of the course. The department will use this evaluation in order to find out how they might need to modify the programme in the future. A summative evaluation will be conducted as outlined by Smith and Ragan(1999,p.352). Those authors explain that in order to evaluate the effectiveness, appeal, and efficiency of instruction, a collection, analysis and summary of data on students ia essential. In our designed programme an exam is built to access students of their mastery on the abilities taught during the programme.Students are to show their capabilities in their understanding and knowledge taught to them by completing the set of homework targeted to them. Students will be graded on from 1 to 5 for their abilities in each of the following sections: Student name Student able to choose a topic n sub-topics Student able to use handouts information Student able to complete the essay Score dated from 1 to 5 1 : poor 2 : Able to understand the writing concept with some guidance 3 : Able to complete the task with help and support 4 : Able to understand the concept and complete the task individually A pre-test and post-test can measure how well learners achieved the learning objectives. However, it usually takes more time and effort to measure things such as whether the learners will use their training. This evaluation phase can extend for months. Upon completion of the programme the students feedback will be collected to further gauge the success of the programme. Questions are also answered on a scale of 1 to 5. 1 is low and 5 is high. The standard questions constructed are as below: Were you satisfied with the content of this course? Were you able to understand the teachers explanation? Were you able to put into practice elements that you learnt? Did you fond the course interesting? On a scale of 1 to 5, what is your general feeling about the course?

Analyzing Itten’s Color Theory in Painting

This essay concentrates on the topic about the seven color contrast which is drawn by a great Swiss expressionist painter named Johannes Itten. Thus, this paper would also render definite attention in analyzing and assessing the use of color in two different paintings which are made by two respective artists, through the use of the said seven color contrast done by Johannes Itten. The paper holds on to the purpose of comparing and contrasting the particular usage of color in the paintings of Leonardo Da Vinci (Virgin of the Rocks) and Jan van Eyck (The Arnolfini Portrait) by means of utilizing the color theory of Itten. The following would be discussed: †¢ Understanding Leonardo Da Vinci’s Virgin of the Rocks †¢ Discussion on Jan van Eyk’s The Arnolfini Portrait †¢ The Virgin Rock and The Arnolfini Portrait At the end of the paper, this would render definite information that would accordingly differentiate Leonardo Da Vinci’s (Virgin of the Rocks) and Jan van Eyck’s (The Arnolfini Portrait) in terms of utilizing colors in their paintings. Understanding Da Vinci’s The Virgin of the Rocks. Leonardo Da Vinci, as one of the great painters in the ancient history of painting, uses an approach and strategy in using color for the â€Å"Virgin of the Rocks† and/or sometimes referred to as â€Å"Madonna of the Rocks† which depicts the same characteristics of contrast between the light and dark.. Hence, as observable and evident in his painting, Leonardo Da Vinci’s primary use of color is set to provide a picture of artistic combination between the light and dark colors. Just like many great painters in his time, Da Vinci’s use of color in his painting is regarded to be monochromatic, wherein he mostly utilized various darker shades, grayer tones, and paler tints that render great detail distinguishing between the light and black. In the said painting, Da Vinci’s usage of light color is specifically situated in providing lucid details of the face and position of the objects and the surroundings that clearly reveals the shade of light and dark colors in the rocks. In other words, Leonardo Da Vinci’s basic usage of light and dark colors in the painting is his own approach in depicting the proper presentation of the effects of lighting in providing clarity and emotion to the visual. Thus, through this comprehensive observation, it can be said that Da Vinci’s use of color in â€Å"Virgin of the Rocks† falls under the category of â€Å"contrast of light and dark† and â€Å"contrast of saturation† in Itten’s seven color contrasts as his painting is mainly composed of light and dark colors which are accordingly and subtly used to signify single depiction. Discussion on Jan van Eyk’s The Arnolfini Portrait As per the painting and work of Jan van Eyck’s entitled â€Å"The Arnolfini Portrait,† which is also referred to as â€Å"The Arnolfini Wedding† and â€Å"The Arnolfini Marriage,† the primary stance and use of color portrays a relative significance and value in composition of the painting. Unlike Leonardo Da Vinci’s â€Å"Virgin on the Rocks,† where he mainly utilized light and dark colors, which resulted to a monochromatic painting, Jan van Eyck’s composition â€Å"The Arnolfini Portrait† is fundamentally filled with bright and glowing colors, which carry a single goal of depicting the wealthy lifestyle of â€Å"Giovanni di Nicolao Arnolfini,† the man who is with his wife in the painting. Jan van Eyck’s primary use of color in the said painting is set to depict life and draw a picture of realism. Thus, van Eyck’s has used different radiant colors to present and improve the accuracy of life and actual picture and fine details of the living room where Giovanni Arnolfini and his wife are standing. In addition this, through the use of radiant and lively colors, Jan van Eyck is able to render definite details in the painting such as the shadow of Giovanni Arnolfini and his wife and the shade of light that comes from the window. The use of bright colors also provides details on the lighting and the ray of light coming from the outside, which passes through the window that reflects on the half part of the chandelier and through the face of Giovanni Arnolfini and his wife. Thus, Jan van Eyck’s use of color for this painting is categorized as the contrast of complements. Virgin of the Rocks and The Arnolfini Portrait Through a thorough analysis and assessment of the two paintings, it is said that there are evident and observable similarities and differences in terms of the use of color. As per the similarities of the two paintings, it is evident that both of the painters, Leonardo Da Vinci and Jan van Eyck, have utilized colors in such a way that it supports their goal of depicting realism and presence of life in their objects in the painting. Thus, the two artist and their paintings are also equipped with the most suitable colors in establishing the presence of lighting and/or the source of luminosity in order to further highlight realism and life. In a sense, it can be said that the paintings and masterpieces of the two artists differ from each other in terms of their specific usage of certain types of colors. In constrast to the painting of Leonardo Da Vinci’s â€Å"Virgin of the Rocks,† Jan van Eyck has utilized mostly radiant and glowing type of colors to be able to highlight realism and enhance the genuine picture of life in Arnolfini’s wealthy life and the beauty of their living room together with his wife. Leonardo Da Vinci, on the other hand, has mainly utilized a combination of light and dark colors to present life and provide details of lighting in his painting, which render and draw the appropriate emotions of the image. In the end, it can be said that the classical paintings of Leonardo Da Vinci and Jan van Eyck, which are entitled â€Å"Virgin of the Rock† and â€Å"The Arnolfini Portrait† are identical in such a way that these two artist have used colors to be able to achieve their main artistic goals, which is that of depicting realism and putting more life into their works. Hence, the two paintings only differ from each other in terms of the particular colors that they use in its composition. As Leonarod Da Vinci has utilized more of the light and dark types of colors, Jan van Eyck has used mostly radiant and lustrous combinations of hues to enhance the quality of his painting and provide for the lively features of his depiction on the life Giovanni Arnolfini.

Equilibrium Experiments

Aim: To investigate the theory of equilibrium via the completion of two experiments which rely on the use of equations TPLcos? +TPMcos?, which can be rewritten as (Mass Ag) cos?+(Mass Bg) cos?. For the second part of the investigation I will try to prove the equation (W*x)/d +weight of a ruler. Introduction In this investigation I will carry out two experiments, which in each case will prove a different aspect of the theory of equilibrium. There are two theories' I wish to prove. The first is † tension (Tpl) in the string Pl is equal to the weight of A and tension in the string pm (Tpm) is equal to the weight of B. For equilibrium the sum of the vertical components of these two tensions must be equal to the weight of c. Which means that: Tpl cos? + Tpmcos? = MassCg which can be written as (MassAg) cos ? +(MassBg) cos ? = MassCg (equ 1) Also: the moment of a force about a point is equal to the magnitude of the force x its perpendicular distance from the pivot. For equilibrium, the moment of the weight about the pivot will be equal to the moment in the opposite direction due to the weight of the ruler. Therefore (W*x)= weight of the ruler times distance d Weight of ruler = (W*x)/d. (equ 2) Diagram Method for experiment a 1. Set up the arrangement shown in figure 1, check that the point p is in equilibrium. 2. Note the value of masses A, B, and C and measure the angles LPO ? and MPO ?. 3. Keep masses A and B constant and note the new value of angles ? and ? for different values of mass C 4. Record results in tabular from. Method for experiment b 1. Set up apparatus as in fig 2. 2. Find point of equilibrium. 3. Note value for the mass used and the distances x and d. 4. Repeat last two stages for several sets of masses and record results in tabular form Calculation These where done on paper by hand for ease of presentation Error Analysis I have generated my errors on the fact that I thought that I could only read the I choose the error of. The way in which I got the final answer out was to run through the calculation twice, once with the answer I got – the error and then again this time with the answer I got + the error. I think that in the first experiment I was a little over the top with the error. I said that I could read the angle to about 5. But when I did the calculation again with the new values. I found that the gap was quite large. And that I was quite close to the true value and that although the value did fall in the gap, the gap could have been a lot smaller. This say to me that the error need not have been so large, and that I read the angle quite well. For exp B Conclusion In conclusion I have found out that equ 1 stand true. In the aim I set out to see if I could prove it I have put in all the results. The answers I get out are generally good. They are the same as the mass or in the cases were they are not they are close and fall well in the range of the errors. Problems with this experiment: the main problem I had with this experiment is the way I was told to find the angle. This way was not that accurate. It left a large margin for error. This is some of the anomalies may have crept in. For the second of the two experiments I found that the mass of the ruler was 0.128g. This was obtained by weighting the ruler on a set of scales. After putting the numbers through the formula for weight of ruler, and then dividing the output by g, which was 10, I managed to get a value for the mass of the ruler. On average this value was 0.119g, which is only about 7% away form the real mass of 0.128g.on farther analysis and after calculating the upper and lower bounds by changing the results by adding or subtracting the errors I found that the outcome from adding the errors to the results and the outcome from subtracting the errors was the same, 0.119g. This meant that the error was not a large enough value to affect the results a significant way. Therefore finally I found that the mass on the ruler to 0.119g this is 7% out for the value, which I recorded as the mass for the ruler. The reason for this is unknown. I can only guess to the reason. One possibility is the mass I recorded for the ruler was out. And as my results are so consistent this is a large possibility.

The Origin and Decline of the Papal States

The Papal States were territories in central Italy that were directly governed by the papacy—not only spiritually but in a temporal, secular sense. The extent of papal control, which officially began in 756 and lasted until 1870, varied over the centuries, as did the geographical boundaries of the region. Generally, the territories included present-day Lazio (Latium), Marche, Umbria, and part of Emilia-Romagna. The Papal States were also known as the Republic of Saint Peter, Church States, and the Pontifical States; in Italian, Stati Pontifici or Stati della Chiesa. Origins of the Papal States The bishops of Rome first acquired lands around the city in the 4th century; these lands were known as the Patrimony of St. Peter. Beginning in the 5th century, when the Western Empire officially came to an end and the influence of the Eastern (Byzantine) Empire in Italy weakened, the power of the bishops, who were now often called papa or pope, increased as the populace turned to them for aid and protection. Pope Gregory the Great, for example, did a great deal to help refugees from invading Lombards and even managed to establish peace with the invaders for a time. Gregory is credited with consolidating the papal holdings into a unified territory. While officially the lands that would become the Papal States were considered part of the Eastern Roman Empire, for the most part, they were overseen by officers of the Church. The official beginning of the Papal States came in the 8th century. Thanks to the Eastern empires increased taxation and inability to protect Italy, and, more especially, the emperors views on iconoclasm, Pope Gregory II broke with the empire, and his successor, Pope Gregory III, upheld the opposition to the iconoclasts. Then, when the Lombards had seized Ravenna and were on the verge of conquering Rome, Pope Stephen II (or III) turned to the King of the Franks, Pippin III (the Short). Pippin promised to restore the captured lands to the pope; he then succeeded in defeating the Lombard leader, Aistulf, and made him return the lands the Lombards had captured to the papacy, ignoring all Byzantine claims to the territory. Pippins promise and the document that recorded it in 756 are known as the Donation of Pippin and provide the legal foundation for the Papal States. This is supplemented by the Treaty of Pavia, in which Aistulf officially ceded conquered lands to the bishops of Rome. Scholars theorize that the forged Donation of Constantine was created by an unknown cleric around about this time, as well. Legitimate donations and decrees by Charlemagne, his son Louis the Pious and his grandson Lothar I confirmed the original foundation and added to the territory. The Papal States Through the Middle Ages Throughout the volatile political situation in Europe over the next few centuries, the popes managed to maintain control over the Papal States. When the Carolingian Empire broke up in the 9th century, the papacy fell under the control of the Roman nobility. This was a dark time for the Catholic Church, for some of the popes were far from saintly; but the Papal States remained strong because preserving them was a priority of the secular leaders of Rome. In the 12th century, commune governments began to rise in Italy; although the popes did not oppose them in principle, those that were established in papal territory proved problematic, and strife even led to revolts in the 1150s. Yet the Republic of Saint Peter continued to expand. For example, Pope Innocent III capitalized on conflict within the Holy Roman Empire to press his claims, and the emperor recognized the Churchs right to Spoleto. The fourteenth century brought serious challenges. During the Avignon Papacy, papal claims to Italian territory were weakened by the fact that the popes no longer actually lived in Italy. Things grew even worse during the Great Schism when rival popes tried to run things from both Avignon and Rome. Ultimately, the schism was ended, and the popes concentrated on rebuilding their dominance over the Papal States. In the fifteenth century, they saw considerable success, once again due to the focus on temporal over spiritual power displayed by such popes as Sixtus IV. In the early sixteenth century, the Papal States saw their greatest extent and prestige, thanks to the warrior-pope Julius II. The Decline of the Papal States But it wasnt long after the death of Julius that the Reformation signaled the beginning of the end of the Papal States. The very fact that the spiritual head of the Church should have so much temporal power was one of the many aspects of the Catholic Church that reformers, who were in the process of becoming Protestants, objected to. As secular powers grew stronger they were able to chip away at papal territory. The French Revolution and the Napoleonic Wars also did damage to the Republic of Saint Peter. Eventually, during the course of Italian unification in the 19th century, the Papal States were annexed to Italy. Beginning in 1870, when the annexation of the papal territory put an official end to the Papal States, the popes were in a temporal limbo. This came to an end with the Lateran Treaty of 1929, which set up Vatican City as an independent state.
