Guidelines on Syllabus for Visually Handicapped students., Schools are expected to rationalise and divide the syllabus of practicums for visually handicapped, students into two halves on the basis of collective guidelines given for the same in the complete, syllabus and as per the convenience of their students. This flexibility is given in view of the special, condition of visually handicapped students .They will, however, be assessed on 15 marks in practical, examination in both the terms as rest of their peers., General Instructions for Investigatory Project, In Chemistry the students of class XI and XII are supposed to conduct a scientific investigations, involving laboratory testing and collecting information from other sources. This project is assessed as, a part of practical examination at the end of year., At the outset, teachers must map appropriate competencies or learning outcomes with real world, problems (projects) that are age appropriate for their students. Students in consultation with their, teacher finally determine the project question for them depending upon their interest and proclivity., A project should ideally arise out of the need felt by the student. Students explore their areas of, interest and narrow down their ideas to a testable hypothesis or problem question., For example: Abdul waits for summers as his favourite fruit watermelon is available in plenty. This, year he noticed that every time he bought a watermelon its colour was dark red and was, exceptionally sweet from inside. This never happened in earlier years. Some watermelons would be, sweet some would not. Abdul were surprised by this observation and worried if the fruit was, adulterated. He thought of conducting a test to find out if fruits and vegetables available in his, locality were adulterated. He reviewed articles and papers on adulteration and found out simple, tests to check adulteration at home. Abdul conducted the test and shared his results with his friend, and teacher. He developed a small manual to help other check adulteration in fruits., There are many issues in our immediate surroundings which need to be addressed. Keen, observation will help identify the problem., Before developing a problem question, students must do research on topics and find out what other, people have already done in the selected area to avoid repetition. During this phase, students, should be encouraged to record the reference of every bit of information they got from different, sources. After developing problem question, students should write down precise testable hypothesis, and design an experiment or procedure to test their hypothesis by collecting and analysing the data, followed by writing conclusion and limitation of the study. Students must also develop a timeline, and checklist about accessibility to resources required, safety of experiment/procedure,, harmlessness of experiments to environment, organisms and other people. Teacher must ensure, that it is doable within a specified period of time and available resources and is appropriately, challenging to a particular student (neither be very complex or longer nor be very easy and short). It, should not culminate into finding information from a book or website., A project could have the following outline:, 1. Statement of Problem- A clear statement of the problem/need that has given rise to the, project, 2. Objectives-General and specific objectives of topic

Page 10 :
3. Introduction-The introduction should describe the relevance of problem or why the problem, is the most appropriate for your inquiry. It should also describe previously known facts, about your problem question with proper bibliography. Introduction towards end briefly, includes hypothesis your hypothesis and the method to test it., 4. Problem question (specific, concrete questions to which concrete answers can be given), and/ or hypotheses, 5. Methods/Procedures Methodology (will your research be based on survey, an experimental, investigation, historical study, ethnographic study or content analysis).Methods describe the, experiments proposed or the observations planned to make and the detailed process of, analysis of data/observations. Methods proposed should be feasible and be able to, adequately answer problem question., 6. Materials/Resources required, 7. Observations/Data gathered, Using the procedures mentioned in introduction, experiments should be conducted and data, should be recorded. Interesting things that happened during the conduct of experiments, should also be recorded., 8. Analysis of data and discussion of result, Data should be interpreted in terms of proposed hypothesis. Data should be tabulated and, interpreted with the help of graphs if possible. The interpretation should be done in an, honest manner even if it does not support proposed hypothesis., 9. Conclusion Reporting and writing up the report, Discussion of new learning from the study may be covered under conclusion. This may have, possible suggestions for future studies., 10. Limitation of the study, The limitations of the study are those features of design or procedure that might have, affected the interpretation of the results of study. The limitations are alternatively, interpreted as flaws or shortcomings due to flawed methodology, observations, small, number of experiments or non-peer reviewed nature of study etc., 11.
