From Scientific Research on Local Seaweeds to Science Classroom: Inquiry-Based Science Laboratory for Undergraduate Students
We demonstrate a new inquiry-based laboratory for teaching and learning of enzyme kinetics which is a fundamental topic taught in undergraduate life science course. The laboratory designed for students was based on our scientific work concerning one type of enzymes (bromoperoxidases) from seaweeds which have great promise for biotechnological applications. In doing so students are more engaged in carrying out the experiment and researcher cum lab instructor has superior pedagogical content knowledge and is better responding to unexpected results because of experiences previously acquired from the conventional research. Our students had to perform the learning cycle activities which they learned more profoundly. Group of students were given background knowledge by the instructor and then were left themselves to plan their own experiments on factors influencing the rate of enzyme catalytic reaction. The results obtained then were compared and contrasted by the students themselves. From observation data, the students were enthusiasm, happiness and competitive spirit. The teaching assistants were asked only for help only briefly at the beginning and then later ignored by the students who more eager to collaborate and consult within the group and to see whether their results were similar or different from others. Naturally the instructor had to conduct a wrap-up consensus session and to clarify main points. This approach helped students develop more effective ways of interpretation of data themselves. Following the laboratory class, the students had to learn in-depth concepts in lecture. The results revealed that students followed the lecture better because they had a feel of what was being presented. From our innovations not only were post-test scores (36.96±6.71) significantly higher than pre-test scores (25.25±6.46) as expected but also students’ knowledge retention was much better than expected.
