From Tootsie Rolls To Composites: Assessing A Spectrum Of Active Learning Activities In Engineering Mechanics

Abstract

Abstract The introduction of active learning exercises into a traditional lecture has been shown to improve student learning. Hands-on learning opportunities in labs and projects provide a primary approach in the active learning toolbox. This paper presents a series of innovative hands-on active learning activities for mechanics of materials topics. These activities are based on a Methodology for Developing Hands-on Active Learning Activities , a systematic approach for efficient and effective activity development, and were robustly evaluated at three institutions of higher learning. These institutions include a research university (The University of Texas, Austin), a four-year primarily teaching institution (The US Air Force Academy) and a community college (Austin Community College in Austin Texas). Seven of the twenty-eight activities have been rigorously evaluated to date. Evaluation consisted of a variety of measures, including student opinion surveys, focus groups, pre/post activity quizzes, exam questions and a concept inventory. In addition, demographic information, student learning styles and Myers-Briggs Personality were measured and are correlated to the student evaluation measures. Data from over 150 students is summarized and insights gained are discussed. In general, students are excited about the hands-on activities in lecture, and they believe the activities enhance their learning. The majority of the assessment data also shows that the active learning activities enhance students’ understanding of the material. While these general findings exist, students’ opinions of the activities do vary with learning styles, institutions and their general understanding in the course. Learning styles, personality type, and perception of performance in the class all have influence on the students’ opinions of the activities and will be measured further in future activity development and evaluation.
