Project Interweave, a 3-year federally funded pilot project, not only provides inservice education for Illinois teachers in District 63, but also endeavors to train a number of teachers to assist participating schools with any type of inservice program. During the project's first year (1967-68), television lessons, which had been planned during the summer by committees of teachers, were broadcast once a week to teachers in participating schools in the fields of science, mathematics, and social sciences. (Language arts skills permeated all the lessons as the "interweave" tool.) The lessons illustrated an inquiry approach to teaching, and their viewings in each school were followed by seminars led primarily by members of the planning committees. The planning committee for social studies also developed four instructional tools, including a simulation game in economics for primary pupils. Alterations have been made for the second year of the project in scheduling and lesson format. For example, subject matter lessons now use an interdisciplinary approach, and other lessons are available on innovative practices such as nongrading. The effectiveness of the inservice project will be determined through systematic observation and reports by principals. Difficulty has been experienced in finding tests which will measure pupil growth under the new teaching methods. (LP)
