A Practical Study on Cooperation with a Guest Speaker in a Science Class : Co-production of a Concept Map

Abstract

We studied the effective use of a guest speaker in career education in regular science education. On two occasions, we conducted classes with the aid of a guest speaker working in a science-based profession. We then investigated the effects of the experiment. During the first class, it was clear that students were able to understand the contents of the lecture and see some connection with their studies. These ties, however, were somewhat limited. Prior to the initial meeting, students had prepared a "concept map", detailing their expectations for the lesson. Before the next class, we discussed the "map" with our guest and informed him of the general structure and content of our course. Once both parties were aware of the other's knowledge base and regular practices, productive interaction was achieved. By the end of the second class, the students were able to place their new found knowledge within the context of the curriculum and understand the relevance and practical application of their studies in professional life.
