The learning cycle approach has survived into the present time as an important instructional strategy (see, for example, the review by Abraham, to Lawson, Abraham, and Renner(1989), the learning cycle originated from the work of Robert Karplus in the Science Curriculum lmprovement Study(SCIS) program for U.S. elementary and junior high schools in the late 1950s and 1960s, and in Chester Lawson's work in biology education in U.S. high schools and universities during the same period. It was from Lawson's project that the famous Biological Science Curriculum Study(BSCS) project had developed during the post-Sputnik reforms in science education.
