“…One variable, laboratory instruction, appears to have a consistent positive influence on students' attitude toward science. Individual research studies, reviews, and summaries of research in science education since the 1970s report that hands-on, activity-based laboratory instruction enhances students' attitude toward science (Gunsch, 1972;Johnson, Ryan, & Schroeder, 1974;Dickinson, 1976;Mallinson, 1976;Fraser, 1980). These reviews and summaries are supportive of the use of the laboratory in the development of attitude toward science.…”
