PRACTICALS B. Sc.
The sub-committee reviewed the existing approved list of practicals and agreed to recommend the practicals as per list for introduction at B.Sc. level. While reviewing the status of B.Sc. Physics practicals the committee strongly felt that the existing format was too highly structured and the students were not getting sufficient training in constructing equipment for innovation. With this in view the Committee recommended as follows:-
a) During the two years of B.Sc. the students be required to perform one mini project, in addition to 12 experiments per section ( i.e. Section-A: 12 Experiments, Section-B: 12 Experiments, + 1 mini project). The distribution of marks between experiments and project would be,
Practical-A : 15 marks, Practical-A : 10 marks,
Practical-B : 15 marks, OR Practical-B : 10 marks,
Project : 10 marks,
__________________________ ____________________________
Total : 30 marks. Total : 30 marks.
While the students would be expected to construct and submit the report of the project, they would be expected to demonstrate working and be examined in detail for the project at the time of final examination.
b) The projects should conform to a standard requiring a level of construction and data acquisition etc. To specify this level, a list of projects with the detailed write-ups was provided by the committee. It would be the responsibility of the colleges to provide the student with major equipment while the students would be expected to provide consumable parts. The teachers would be expected to help and guide the students in the choice, construction and use of the projects to obtain data.

RECOMMENDATIONS FOR B.SC.
The Board of Studies endorsed the following recommendations of the curriculum committee along with certain modifications.
1. The Committee approved and finalized the decision reached at, in the earlier meeting of March, Dec. 1995 and unanimously recommended to adopt Physics by D. Halliday, Resnick, K. S. Krane. (4th Edition Published by John Wiley and Sons: 1992) as the text book.
2. The Committee decided that all questions for future B.Sc. Exams be taken from this book. This may include both the conceptual questions and problems at the end of each chapter. The sub- Committee noted with satisfaction that the above book has already been adopted by the Karachi University and recommended by the Multan University. The availability of book should be made easier and the UGC be asked to contact both the publishers & the local book authorities such as the National Book foundation of Pakistan.
3. The Committee recommended that the pattern of question papers should be as follows: -
a) Numerical Problems. 40%
b) Theoretical questions. 40%
c) Conceptual questions. 20%
(Labelled as questions at the end of chapters H.R.K)
With the passage of time, the weightage given to theoretical questions be reduced in favour of Numerical and conceptual questions.
4. The committee recommended very strongly that the spirit of book viz. problem solving and analysis was only possible if the examinations are held more frequently. All Universities be urged to hold separate examinations i.e. B.Sc. Part-I & Part-II. This would make it possible for the students to concentrate on portion of the course at one time, thereby improving the performance.
The committee felt in principle that decentralization of examination is imperative.
5. The Committee considered the following aspects while deciding the list of Practicals:
a) Experiment proposed should as for as possible avoid new and expensive experiments and try to utilize the existing facilities to the maximum. If new equipment is needed it should be of the kind which is readily
available in the local market.
b) Experiment should concentrate both on illustrating the physical principles & developing some experimental skills of students.
c) The Committee endorsed the comments of the sub-committee dated December 1995 subject to the above changes and agreed to have them approved as an appendix with these recommendations.
6. The Committee endorsed the idea of double physics, Mathematics alternative to Physics mathematics and noted that the logistics of this be looked into separately calling the need for qualified master trainers, to train our teachers in this field. Only when the required training, equipment and funds have been provided, the same will be implemented.
7. The Committee also requests to UGC that if examination are to be improved, the efforts required in preparing & grading quality papers be properly appreciated. In particular the remuneration for this purpose be increased substantially & the paper work/unnecessary formalities be eliminated.
8. The element of choice in examinations must be drastically reduced. The committee recommended that the choice not be more than 50% e.g. a student is required to do 10 questions out of 15. This step is essential to eliminate the partial coverage of course by the students & teachers.
9. The Committee felt that a number of affiliated colleges are functioning in a highly unsatisfactory manner. Particularly in relation to experiments and laboratory work. The committee recommend that affiliation committee be formed/activated at each University to continuously visit and inspect the affiliated colleges. Those colleges who do not fulfill minimum requirements and standards of B.Sc. teaching have their affiliation suspended.
10. The Board of Studies strongly recommend to increase marks per paper to fifty(50) in order to have better marking scale. The Board feels that this will only be possible when the same standard of marks is adopted in all other subjects taught at B.Sc level.
