This 3-week summer project was designed to (1) identify and improve the teaching capabilities of under-prepared junior high school mathematics and science teachers and (2) acquaint college and junior high school teachers with current techniques in mathematics and science at the two different levels (college and junior high) and continue cooperative activities between them. In 1985, 20 teachers participated in a National Science Foundation summer institute. The first 2 weeks were devoted to training in mathematics and science content and teaching techniques. Lectures, demonstrations, and discussions emphasized problem-solving, classroom computer use, discovery techniques, the importance of proof, laboratory techniques, and encouragement of research by students and teachers. During the third week, participants were able to test these concepts and techniques by working with students in the college's annual junior high school math and science camp. Teacher self-evaluation of teaching skills at the beginning and end of the 3-week program showed higher ratings in each of six skill areas upon program completion. Participant ratings of the program were high. In a survey after one semester back in the classroom, each participant described at least five new classroom and professional activities initiated because of experiences at the summer institute. Administrators also attributed increased teacher effectiveness to program participation. (MSE)
