The present book is an abridged version of the author’s doctoral dissertation submitted to the Nagpur University in 1983. It is a novel work in the field of mathematics education. It is also a premier thesis in India involving two important models of teaching in the information processing family developed by Bruce Joyce and Marsha Weil, namely, Ausubel’s Advance Organizer Model and Bruner,s Concept Attainment Model. The researcher has compared the two models on the various criteria of concept-acquisition in mathematics and brought forth a few valuable conclusiomns.The researcher’s is characterised by discovery of new facts and bears ample evidence of researcher’s profound scholarship, his capacity for critical thinking and sound judgment. The literary presentation is superb and evinces an organized mind behind it. In view of fresh emphasis on mathematics education envisaged in the new National Policy of Education, 1986 and the rigorous efforts by the National Council of Educational Research and Training to orient teachers in models of Teaching, this book should serve as a valuable reference to all teachers, resource persons and educational researchers, resource persons and educationists in India and abroad.

(Mathematics), Ph.D. (Education)courses at the Post-Graduate Department of Education, Nagpur University, Nagpur. He has a unique distinction of having taught at all levels from primary to Post-Graduate which has given him rich experience of and deep insight into educational problems. His basic discipline being mathematics, he devoted himself to the cause of improving mathematical instruction and in the process got involved in the study of ‘models of teaching’. The present book is the result of his pains-taking work at the Centre of Advanced Study in Education, M.S. University Baroda where he was a teacher fellow. Dr. Chitriv has been a meritorious student, a distinguished teacher and an astute researcher throughout his career. He has presented papers on a wide variety of subjects such has ‘Analysis of Thinking’, ‘Cognitive learning Processes’,’ Mathematical Creativity’ and ‘Models of teaching’ organized by the NCERT throughout the country and National Seminar on Methodology of Educational Research held at the CASE Baroda. He participated in many national projects including those on ‘development of Training Strategy’, production of instructional Material for Distance Education’ and ‘Developing Question Bank on Teaching of Mathematics’. A few ambitious research scholars are working for their Ph.D. under his guidance.
