To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The…

Compares the relative effects of hands-on and teacher demonstration laboratory methods on declarative knowledge and procedural knowledge achievement. Reports that students in the hands-on class were better on the procedural knowledge test than students in the demonstration class. (Author/YP)
