The undergraduate science programme was launched at the Indira Gandhi National Open University (IGNOU) in 1991-92 with an enrolment of 1,210 students. The programme was well received, and enrolments increased over the years. However, the success rates have not kept pace with enrolment.In this paper, the authors report the results of an evaluation of the undergraduate physics programme at IGNOU. The evaluation, the first of its type for this programme, adapted the major tenets of the CIPP model. The findings are based on the responses from a randomly chosen sample of 509 learners across India. The methods employed for the study include records, document, and database analysis, surveys, and case studies.Although the University has enhanced access to higher science education, the attrition rate is high (73%), and the success rate is low. The authors recommend that the University review and reorient its strategies for providing good quality, learner-centred higher education in science subjects. The programme should address the concerns of the learners about the effectiveness of the student support systems, the difficulty level, and the learner-friendliness of study materials with the goal of achieving long-term sustainability while maintaining parity with the conventional system. The need for improving the presentation of the courses and simplifying the mathematical details is emphasised.

In the undergraduate physics laboratory, a student is expected to make precise measurements, hone investigative skills and discover the interplay between experimentation and fundamental principles underlying physical phenomena. But in India, the mainstream conventional UG physics laboratory instruction has all along been cookbook in nature. In such a scenario, incorporating innovative and meaningful laboratory experience in Open and Distance Education programmes becomes a formidable challenge. Recently we evaluated the physics laboratory courses, which are integral to the B.Sc (Physics) programme of IGNOU offered at a distance, for their quality, relevance and effectiveness. Our findings reveal that these courses are being received well particularly by those students who are pursuing the B.Sc (Major) in Physics. The success rates improve as learners evolve in the system and their satisfaction levels are high. However, factor analysis of learners' perceptions brings forth six factors guided approach, student-centered learning and assessment, emphasis on self-learning, use of multimedia and innovative non-conventional teaching strategies, increased student participation and emphasis on problem solving as key determinants for further improving the quality of learning in physics laboratory.

Rajawat for their whole hearted support. We would also like to thank Shri Shashikant A Sharma, Dr Markand Oza and the entire VEDAS team for hosting the RISAT-1 mosaic at VEDAS. We also put on record our sincere thanks to all those who directly or indirectly helped us in this work. d d A dh i Mi Jayaprasad P and Arundhati Misra
