A summary of the overall methodology in science education is presented in this book for the purpose of serving as a source book for teachers, scientists, and science educators in India. The book is divided into ten chapters. The first two chapters are concerned with revolution in science teaching abroad and science education history in India, especially the development of Indian tradition. The following chapters are related to science education objectives and their taxonomy; curriculum construction and development; learning processes and theories and psychological bases of Skinner, Wertheimer, Duncker, Piaget, and Bruner; methods of achieving behavioral objectives; lesson planning, illustrative units, and examples of lesson plans; science laboratory work; evaluation techniques; and important factors enabling promotion of students' changes in thinking and attitudes toward sciences. Efforts are made in this book to orient the Indian science education community toward experimenting and innovating and less toward perpetuating along the age old tracks. (CC)
