A Comparison of Two Methods of Teaching Molecular Architecture to High School Chemistry Students.
Halsted, Douglas Alan
This investigation explored the question of how high school chemistry students best learn three-dimensional molecular, ionic, and metallic structures in CHEM Study (Freeman, 1963). The experimenter compared the achievement, attitude, and instructional preferences of 110 randomly selected students taught by two different methods: (1) student assembly of orbital models, and (2) teacher lecture-demonstration assembly of orbital models. In the 21-day study, the experimental group assembled orbital models during scheduled laboratory time and the control group spent scheduled laboratory time being taught by teacher lecture-demonstration assembly of orbital models. Among data collected and analyzed by multivariate analysis were first semester chemistry achievement, attitudes toward chemistry, and preferences for different types of instruction. It was concluded that students who assembled three-dimensional orbital models achieved at a higher level on a test of three-dimensional crystal models than did students who were taught by teacher lecture-demonstration assembly of orbital models and that most students prefer a combination of teacher lecture-demonstration and student assembly of orbital models.
