In the belief that uses of many different media will help motivate students, this book was compiled to assist tutors, particularly in science and mathematics, in using multi-media. Special emphasis was placed on increasing the tutor's understanding of mathematics and science. Following a chapter on the history and development of instructional technology, classroom media equipment (such as films, filmstrips, transparencies, pictures, tapes, etc.) is described with its advantages and disadvantages and instructions on determining appropriate usage. Some simple techniques for using media are outlined, including uses for easily obtained household items. Two chapters cover some elementary mathematics and science concepts and the applications of media to tutoring in these areas. A section on the handicapped child and adaptation of media to his situation is also included. The final chapter comments on the tutor's role, and sources of free and inexpensive materials are listed with the bibliographies. While the subject matter is generally from the elementary level, the discussions about the media are intended for all levels. (JM)
