Directed Discovery, Form of Presentation, and Laboratory Schedule for Nonscience Students in the Freshman Chemistry Laboratory.
Hittle, David Russell
Evaluated was achievement by college freshman students in a chemistry laboratory course. Twenty-eight sections, a total of 292 students, were grouped into six sections with written direction in a structured laboratory experiment schedule, six sections with verbal direction in a structured schedule, and sixteen sections with an unstructured schedule of experiments. Teaching assistants instructed schedule of experiments. Teaching assistants instructed all sections. The course final examination and laboratory final examination of hierarchial cognitive questions and the "Cognitive Preference Test: High School Chemistry" were administered to obtain data on achievement and cognitive preference. Analysis of variance was applied to data in 2x2x2 treatments by "SAT" math scores. It was concluded that student achievement and cognitive preference were not significantly affected by type of laboratory schedule experience; written form of laboratory direction was better than verbal form in respect to achievement; and quantitative ability of students as measured by "SAT" math scores had significant effect on both course and laboratory final examination achievement and on cognitive preference for factual and critical questioning solutions in problem solving situations.
