A behavioral analysis of the laboratory learning process, redesigning a teaching unit on recrystallization

Teaching Distillation Knowledge: A Video Film about Distillation Bridging a Gap Between Theory and Practice

“…However, the learning results of such experiments have been questioned by many authors, especially for the organic laboratory (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). The problem is that students working with optimized laboratory instructions are not always aware of the rationale behind these instructions.…”

“…We thought this would be better preparation for the research work students meet later on. In this spirit, so-called design-oriented experiments were developed in our department for first-and third-year courses on separation techniques such as crystallization (7) and distillation (12), on chemical measurements (13), and on organic and inorganic synthesis (14 -16).…”

Chemical Education Research in the Laboratory Environment: How Can Research Uncover What Students Are Learning?

“…The student has an incomplete selection rule that reflects the student's belief that bases have no hydrogen in them. (3) The map indicates a possible misconception that bases are targe because they can expand. (4) The map shows six acceptable links and 15 unacceptable links.…”

The development of statistical concepts in a design-oriented laboratory course in scientific measuring

“…This means that a prescription-oriented laboratory course may contribute to a gap between theory and practice. On this basis several authors question the usefulness of prescription-oriented laboratory courses in this Journal (2)(3)(4)(5)(6)(7).…”
