On Improving “Thought with Hands”
Résumé
To improve the application of thought in laboratory exercises and to develop many useful skills in undergraduate Chemical Engineering students, a laboratory course consisting of dual-step laboratory exercises and a report of recommendations/innovation from the student was introduced for the fluid mechanics laboratory. The first step of the dual-step exercise consisted of a standard exercise (concise version) followed by rigorous analysis of the data; the second step consisted of either designing and carrying out a new experiment/addressing a different question with the same/slightly modified experimental set-up, or formulating and testing hypotheses for unexpected trends in the data. Students worked in groups under the direction of an elected group leader. The need, details, outcomes, and experiences of the dual-step laboratory exercise/recommendations report are discussed, and some samples of student exercises are presented. The student and laboratory staff responses are also presented.
