It is an instrument for the spiritual development as well as the material fulfillment of human beings. Within the context of Islamic perception, education is an instrument for developing the attitudes of individuals in accordance with the values of righteousness to help build a sound Islamic society. After independence in 1947 efforts were made to provide a definite direction to education in Pakistan. Quaid-i-Azam Muhammad Ali Jinnah laid down a set of aims that provided guidance to all educational endeavours in the country. This policy, too has sought inspiration and guidance from those directions and the Constitution of Islamic Republic of Pakistan. The policy cannot put it in a better way than the Quaids words: You know that the importance of Education and the right type of education, cannot be overemphasized. Under foreign rule for over a century, sufficient attention has not been paid to the education of our people and if we are to make real, speedy and substantial progress, we must earnestly tackle this question and bring our people in consonance with our history and culture, having regard for the modern conditions and vast developments that have taken place all over the world. There is no doubt that the future of our State will and must greatly depend upon the type of education we give to our children, and the way in which we bring them up as future citizens of Pakistan. Education does not merely mean academic education. There is immediate and urgent need for giving scientific and technical education to our people in order to build up our future economic life and to see that our people take to science, commerce, trade and particularly well-planned industries. We should not forget, that we have to compete with the world which is moving very fast towards growth and development. At the same time we have to build up the character of our future generation. We should try, by sound education, to instill into them the highest sense of honour, integrity, responsibility and selfless service to the nation. We have to see that they are fully qualified and equipped to play their part in various branches of national life in a manner which will do honour to Pakistan. These desires of the Quaid have been reflected in the Constitution of the Islamic Republic of Pakistan and relevant articles are: The state shall endeavour, in respect of the Muslims of Pakistan: to make the teachings of the Holy Quran and Islamiat compulsory and encourage and facilitate the learning of Arabic language to secure correct and exact printing and publishing of the Holy Quran; to promote unity amongst them and the observance of Islamic moral standards; Provide basic necessities of life, such as food, clothing, housing, education and medical relief for all such citizens irrespective of sex, caste, creed or race as are permanently or temporarily unable to earn their livelihood on account of infirmity, sickness or unemployment; Remove illiteracy and provide free and compulsory secondary education within minimum possible period. Enable the people of different areas, through education, training, agricultural and industrial development and other methods, to participate fully in all the forms of national activities including employment in the service of Pakistan; The State shall discourage parochial, racial, tribal, sectarian and provincial prejudices among the citizens. Reduce disparity in the income and earnings of individuals, including persons in various classes of the service of Pakistan. Steps shall be taken to ensure full participation of women in all the spheres of national life. The vision is to transform Pakistani nation into an integrated, cohesive entity, that can compete and stand up to the challenges of the 21st Century. The Policy is formulated to realize the vision of educationally well-developed, politically united, economically prosperous, morally sound and spiritually elevated nation. OBJECTIVES To make the Quranic principles and Islamic practices as an integral part of curricula so that the message of the Holy Quran could be disseminated in the process of education as well as training. To educate and train the future generation of Pakistan as true practicing Muslims who would be able to usher in the 21st century and the next millennium with courage, confidence, wisdom and tolerance. To achieve universal primary education by using formal and informal techniques to provide second opportunity to school drop-outs by establishing basic education community schools all over the country. To meet the basic learning needs of a child in terms of learning tools and contents. To expand basic education qualitatively and quantitatively by providing the maximum opportunities to every child of free access to education. The imbalances and disparities in the system will be removed to enhance the access with the increased number of more middle and secondary schools. To ensure that all the boys and girls, desirous of entering secondary education, get their basic right through the availability of the schools. To lay emphasis on diversification of curricula so as to transform the system from supply-oriented to demand oriented. To attract the educated youth to world-of-work from various educational levels is one of the policy objectives so that they may become productive and useful citizens and contribute positively as members of the society. To make curriculum development a continuous process; and to make arrangements for developing a uniform system of education. To prepare the students for the world of work, as well as pursuit of professional and specialized higher education. To increase the effectiveness of the system by institutionalizing in-service training of teachers, teacher trainers and educational administrators. To upgrade the quality of pre-service teacher training programmes by introducing parallel programmes of longer duration at post-secondary and post-degree levels. To develop a viable framework for policy, planning and development of teacher education programmes, both in-service and pre-service. To develop opportunities for technical and vocational education in the country for producing trained manpower, commensurate with the needs of industry and economic development goals. To improve the quality of technical education so as to enhance the chances of employment of Technical and Vocational Education (TVE) graduates by moving from a static, supply-based system to a demand-driven system. To popularize information technology among students of all ages and prepare them for the next century. To emphasize different roles of computer as a learning tool in the classroom learning about computers and learning to think and work with computers and to employ information technology in planning and monitoring of educational programmes. To encourage private sector to take a percentage of poor students for free education. To institutionalize the process of monitoring and evaluation from the lowest to the highest levels. To identify indicators for different components of policy, in terms of quality and quantity and to adopt corrective measures during the process of implementation. To achieve excellence in different fields of higher education by introducing new disciplines/emerging sciences in the universities, and transform selected disciplines into centres of advanced studies, research and extension. To upgrade the quality of higher education by bringing teaching, learning and research process in line with international standards.

Exercises At least one exercise based on each of the above mentioned standard experiments making the total experiments equal to 50 TEACHING STRATEGIES Physics should not be taken as a collection of facts, and teaching of physics should not emphasize memorization of formal statements by rote, mechanical solution of problems by formulae or carrying out measurements by following given detailed instructions. The teachers should be well acquainted with the aims and objectives of the course. To present physics in a lively, exciting and intelligible way, emphasis should be placed on teaching for understanding by organized investigation, learning and discussion. A good demonstration can be used to stimulate learning. It is intended that consideration of everyday industrial and technological applications should pervade the course. Social, economic and environmental issues should also be considered where appropriate. Quantitative treatment is a feature of physics. However, teacher must keep the emphasize on the understanding of the physical interpretation of theoretical formulae and experimental data. An investigation approach to practical work is essential. Individual student project promote creativity and demonstrate the students mastery of scientific principles involved. Independent use of apparatus by the students develop manipulative skills. The development of psychomotor skills such as correctly manipulating various instruments is an important objective of physics course. Practical work is essential for students to gain personal experience of physics through doing and finding out. Another important objective of science teaching is to develop attitude of thinking in students. Teachers are encouraged to design their lessons in such a way that suitable questions avid activities are incorporated in order to develop various types avid levels of thinking in students, including analysis, evaluation, critical thinking and creative thinking. Teachers capable in content areas may opt the teaching strategy that matches with psychology of the students. The strategy like posing problems, discussion, investigations, and solving the problems with the involvement of the students may provide an ample opportunity in conceptual clearance of a content. In general student centred and interactive approaches are useful in providing suitable learning experiences for stimulating and developing higher level thinking and are highly recommended. Teachers may consider to adopt a variety of strategies from the following spectrum which ranges from very teacher-centred methods to very-students centred methods.  SHAPE \* MERGEFORMAT  SPECTRUM OF TEACHING METHODS Teachers should choose appropriate teaching methods in accordance with the topic/skill to be taught as well as the interest and abilities of their students. The following are some factors to be considered when deciding on the teaching methods for a particular topic: Learning objectives to be achieved Ability of students Subject matter Availability of resources Amount of time available ASSESSMENT AND EVALUATION Assessment, appraisal, or evaluation is a means of determining how far the objectives of the curriculum have been realized. What really matters is the methodology employed for such determination. As is now recognized, performance on the basis of content-oriented tests alone does not provide an adequate measure of a students knowledge and ability to use information in a purposeful or meaningful way; the implication, then, is that effective and rewarding techniques should be developed for evaluating the kind and content of teaching and learning that is taking place and for bringing about improvement in both. The following points, while developing the tests/questions may be kept in view: 1. Proper care should be taken to prepare the objective-type and constructed-response questions relating to knowledge, comprehension, application, analysis and synthesis, keeping in view the specific instructional objectives of the syllabus and the command words for the questions. 2. There should be at least two periodic/monthly tests in addition to routine class/tests. Teachers are expected to develop and employ assessment strategies which are dynamic in approach and diverse in design. When used in combination, they should properly accommodate every aspect of a students learning. 3. In addition to the final public examination, two internal examinations should be arranged during the academic year for each class. 4. Classroom examinations offer the best and most reliable evaluation of how well students have mastered certain information and achieved the course objectives. Teachers should adopt innovative teaching and assessment methodologies to prepare the students for the revised pattern of examination. The model papers, instructional objectives, definitions of cognitive levels and command words and other guidelines included in this book must be kept in view during teaching and designing the test items for internal examination. DEFINITION OF COGNITIVE LEVELS Knowledge: This requires knowing and remembering facts and figures, vocabulary and contexts, and the ability to recall key ideas, concepts, trends, sequences, categories, etc. It can be taught and evaluated through questions based on: who, when, where, what, list, define, describe, identify, label, tabulate, quote, name, state, etc. Understanding: This requires understanding information, grasping meaning, interpreting facts, comparing, contrasting, grouping, inferring causes/reasons, seeing patterns, organizing parts, making links, summarizing, solving, identifying motives, finding evidence, etc. It can be taught and evaluated through questions based on: why how, show, demonstrate, paraphrase, interpret, summarize, explain, prove, identify the main idea/theme, predict, compare, differentiate, discuss, chart the course/direction, report, solve, etc. Application: This requires using information or concepts in new situations, solving problems, organizing information and ideas, using old ideas to create new one and generalizing from given facts, analyzing relationships, relating knowledge from several areas, drawing conclusions, evaluating worth, etc. It can be taught and evaluated through questions based on: distinguish, analyze, show relationship, propose an alternative, prioritize, give reasons for, categorize, illustrate, corroborate, compare and contrast, create, design, formulate, integrate, rearrange, reconstruct/recreate, reorganize, predict consequences etc. DEFINITION OF COMMAND WORDS The purpose of command words given below is to direct the attention of the teachers as well as students to the specific tasks that students are expected to undertake in the course of their subject studies.

The definitions of command words have also been given to facilitate the teachers in planning their lessons and classroom assessments. Analyse: Describe with the use of graphs how information on two or more variables is related to other variables. Apply: Demonstrate the solution of problems by using the specified procedures. Associate: Show the inter connection of phenomena or facts. Calculate: Is used when a numerical answer is required. In general, working should be shown, especially where two or more steps are involved. Define (the term Only a formal statement or equivalent paraphrase is required. or terms): No examples need to be given. Demonstrate: Implies that the candidate is expected to show how one thing is related to another, usually it is a reference to theory but sometimes it is physical manipulation or experiment. Derive: Deduce stepwise of formula from a general from principle or rule. Describe: To state in words (using diagrams where appropriate) the main points of the topic. It is often used with reference either to particular phenomena or to particular experiments. In the former instance, the term usually implies that the answer should include reference to (visual) observations associated with the phenomena. Determine: Often implies that the quantity concerned cannot be measured directly but is obtained by calculation, substituting measured or known values of other quantities into a standard formula, e.g. relative molecular mass. Differentiate: Identify those characteristics which are the defining features of two concepts or phenomena. Discuss: To give a critical account of the points involved in the topic. Draw/Sketch: implies a simple freehand sketch or diagram. Care should be taken with proportions and clear labeling of parts. Explain: May imply reasoning or some reference to theory, depending on the context. Give examples: Name specific instances or cases to demonstrate the occurrence of an event or existence of a situation or phenomenon. Identify: Describe with specific examples how a given term or concept is applied in daily life. List: Requires a number of points, generally each of one word, with no elaboration. Where the number of points are specified, this should not be exceeded. Name: Mention the commonly used word for an object. Prove: Demonstrate by logical or numerical evidence. Recognize: Involves looking at a given example and stating what it most probably is. Relate: Describe how facts or phenomena depend upon, follow from or are part of another. Represent: Draw a graph to show the connection between two variables. Show: Demonstrate with evidence. Solve: Deduce in simple numerical terms. State: Implies a concise answer with little or no supporting argument, e.g. a numerical answer that can be obtained by inspection. Use: Apply the given information to solve a problem. RECOMMENDED REFERENCE BOOKS In contrast to the previous practice the examination will not be based on a single textbook, but will now be curriculum based to support the examination reforms. Therefore, the students and teachers are encouraged to widen their studies and teaching respectively to competitive textbooks and other available material.
