Technological and Engineering Literacy/Philosophy of Engineering
This work describes the application of a computerized tool to assess systems thinking capabilities of non-engineering students in an engineering literacy course and novice engineering students in an introductory engineering course. The program can analyze any block diagram node-and-link map of a system created by a student and then compare this to an expert-generated diagram. A similarity rating is then produced. The ability to describe a technological system in the form of a diagram is an important element of engineering literacy. Creating a diagram that shows how system inputs are transformed into outputs by a network of interconnected components is also one characteristic of systems-level thinking. In this study students are asked to extract information from multiple sources to create a systems-level block diagram that describes how a technological system works. Evaluating student-developed diagrams or concept maps is a time-consuming challenge for educators. We report results from preliminary testing of a computerized tool that compares student diagrams to an instructor-developed reference diagram. The rating of the student diagrams by the tool is in reasonable agreement with by-hand grading of the student diagrams by the instructor. Potential ways to improve the tool are discussed. This work has applications in promoting technological and engineering literacy by making it easier to evaluate engineering competencies that are different from numerical problem solving.
