Description
Summary:Absences from school present a major obstacle to students' gaining understandings of concepts developed in class. Moreover, teachers' finding effective ways for students to make up missed a continual problem, especially for laboratory-based science classes. In an exploratory study, we investigated an alternative procedure for making up missed class work: viewing a quasi-interactive videotaped presentation of missed portions of a learning cycle in chemistry. Two treatment groups were involved. One group of students completed data sheets while watching a videotape, then wrote answers to questions posed by the videotaped instructor. This procedure simulated make-up work. A second group of students participated in a conventional learning cycle: exploration, conceptual invention and concept application. Results demonstrate that teachers can videotape investigations to conveniently and effectively use as make-up assignments for a chemistry learning cycle.
