The Effects of an Independent Laboratory Investigation on the Critical Thinking Ability and Scientific Attitude of Students in a General Microbiology Class.
Norton, Sylvia; And Others
To demonstrate that properly designed laboratory instruction does provide affective and higher order learning benefits, an experiment was carried out in two replications. The subjects were 80 students enrolled in General Microbiology at Wallace Community College, Alabama. Students were randomly assigned to experimental and control groups. The experimental group was randomly assigned a culture of bacterium to be identified. Using references and a list containing their unknowns, they were told to work independently. Instructors provided no help except supervision for safety purposes. The control group continued with step-by-step verification laboratory exercises, working in pairs with direct supervision and instruction. Following three weeks of treatment, the Watson-Glaser Critical Thinking Appraisal and then the Scientific Attitude Inventory were administered. Results indicate that the treatment of the independent laboratory investigation did not have a significantly different effect on the dependent measures of critical thinking ability and/or scientific attitude when compared to the effect of the performance of verification laboratory exercises by a control group.
