Abstract
The importance of laboratory instruction for science students is widely recognized, although this is a question in tertiary education that remains largely unresolved. In this work a proposal for evaluating laboratory instruction in a plant physiology course is presented and examples of questions used for one of the topics covered in the course are shown. The proposal includes the use of specifically designed multiple choice questions (MCQ) in the exams to assess the cognitive domain. Different items used in the plant physiology exams during the 2000–2012 period to evaluate two of the topics were categorized using the blooming biology tool. The questions were classified as lower- (memorization) and higher- (critical thinking) order cognitive skills (LOCS and HOCS, respectively) plus an intermediate order, LOCS/HOCS (application). Though MCQ have been indicated to be prone to evaluate mainly rote memory, our results show that less than 25% of the questions used belonged to the LOCS category. Scores obtained by the students for these MCQ were similar for theory and laboratory instruction. The evaluation model presented is easily transferable to assess a great variety of practical laboratory activities of different scientific disciplines and helps to avoid the dichotomy theory/practice usually found among students.
