CURRICULUM FOR PHYSICS GRADES IX- XII 175 Guidelines for Developing Teaching Learning Resources GUIDELINES TO TEXTBOOK AUTHORS An important dimension of curriculum is the translation of learning experiences or contents at the proper cognitive level of the target students. It is highly technical and delicate task to assist both teachers and students in learning and transmission of the life experiences. The concept to be introduced be explained informally before providing the formal definition or statement along with tangible examples from real life situation. The solved examples and the exercises should cover the whole range of variety of questions and their applications in the everyday life. Keeping this strategy in view, the author should observe the following guidelines while writing the textbooks. Learning objectives expected to be achieved in each chapter should be prominently stated at the beginning of the chapter. Headings and sub headings should be clearly indicated. Key words, terms and definitions should be highlighted in the text. Concepts, application and relationships should be developed from concrete to abstract or simple to complex. Provide transition from previous information covered and new information presented. The intended level and scope of treatment of each content/concept is defined by the desired learning outcomes identifying learning abilities, Investigation Skills/ Laboratory work and relevance with science, technology and society (STS). The intended learning outcomes mentioned under STS should preferably be developed through novel questions or numerical problems on real life situations. The language used in the text should be concise and simple, consisting of short sentences using active tone and should be understandable to the students independently. Ensure gender equity, textual matter urban/rural oriented and relevant to daily life. The text should be supported with art i.e. illustrations and photographs possibly in colour which should be clear, properly labeled and captioned to make the substance interesting and stimulating. Concepts, information and examples should match the sequence and content of learning outcomes. The contributions of Muslim and Pakistani Scientists may be highlighted appropriately wherever related.


CURRICULUM FOR PHYSICS GRADES IX- XII 176 The text should be free from material repugnant to Islamic and Pakistani Ideology. Examples and applications from local environment should be preferred. SI units and terminology should be used all over in the text. However, conversion tables with other units can be given as additional information. Uniformity be maintained in symbolic representation of physical quantities and values of constants throughout in the text and in numerical problems. Answers to the numerical problems should be quoted in scientific notation with correct number of significant figures and units. Solved numerical examples and end of chapter numerical problems should be based on variety of situations in novel manner and be related to local environment, culture and real life situations. Boxed “Tid bits”, “interesting information”, “do you know”, and “point of ponder” may be given to highlight additional information alongwith the description of concepts particularly related to STS connection through inquiry process. Interesting sidelights such as case studies, discoveries, related technologies etc. may be given in the form of “boxed essays”. Tables, flow charts/diagrams and concept maps may be given wherever appropriate. Reference of the experiments given in the practical manual should be made with the related topics given in the text. Coherent and precise summary should be given at the end of each chapter. Several forms of questions/activities should be given at the end of each chapter. They should test not only knowledge but particularly the higher abilities such as understanding, handling information, analyzing, application of ideas and solving problems and relevant Investigation Skills/ Laboratory work and processes. For this purpose, there may be: ‘Self Quiz’ MCQs’, Review question, ‘Short questions’, Essay type questions, and thought /free response questions. Some thought provoking questions may also be given within the chapter. All questions should be very appropriately and clearly worded/constructed to test varying abilities and Investigation Skills on the basis of Bloom’s taxonomy. The amount of information to be covered by the chapter must match the number of hours of instructional time.


CURRICULUM FOR PHYSICS GRADES IX- XII 177 A comprehensive glossary of terms and index should be given at the end of the book. The teachers guide and workbooks should also be developed alongwith textbook which should include suitable strategies that a teacher can adopt for teaching a particular topic and should contain instructions how to explain a topic and how to show relevant demonstration. A practical manual for the students should also be written to support practical work. CONCEPT MAPPING A particularly good way to organize information about a problem or subject is to construct a "concept map." Construction of concept maps helps us pull together information we already know about a subject and understand new information as we learn. It is versatile tool for assisting and enhancing many of the types of thinking and learning that we are required to do. Concept mapping helps students fulfill high-quality and meaningful learning outcomes in science. Maps provide concrete visual aids to help organize information before it is learned. Students can make their own maps while they learn, and examine the changes in their thinking as they construct their understanding. Maps can also be made as a type of assessment at the conclusion of lessons. Concept maps show a definite relationship between big ideas and small ideas, thus clarifying the difference between details or specifics and the big idea or subordinate concept. This can be helpful when a teacher must decide how much emphasis to give to specific facts as compared to concepts in a lesson. The concept maps also provide visual imagery that can help students recall information and see relationships between concepts. Concept maps show hierarchies of ideas that suggest psychologically valid sequences. These hierarchies may not match the linear sequence, or outline, that a teacher has decided to use for a presentation.
