Title: Enhanced Lectures via Worksheets and 3D Computer ModelsAuthors: Eunice Yang and Beverly WithiamAbstractThe effectiveness of lecture worksheets and 3D computers models on student learning in theundergraduate Statics course is investigated. Statics is a course that requires many students toreproduce time consuming schematics during lecture. These schematics begin with simple 2Dsystems at the start of the semester and progress towards more complicated 3D systems taxinglecture time even further. Also, the introduction of 3D structures and force systems in Staticscontinues to be a challenge to students with poor spatial visualization skills. To address theseproblems, lecture worksheets containing pre-drawn schematics were developed for the entireStatics curriculum. In addition, 3D computer models of example problems solved in class weremanipulated to clearly show views that would otherwise be difficult to visualize by thesestudents. The use of these teaching aids allowed the instructor additional time to facilitate higherlevel learning activities such as peer-to-peer instruction and team problem solving activities. Theeffectiveness of these teaching tools was evaluated using a Concept Inventory and the PurdueVisualization of Rotations Test. Scores from these tests were correlated with student GPAs andStatics pre-requisite course grades. The results of this research show improved understanding ofStatics by students with low GPAs and pre-requisite course grades in comparison to the controlgroup who did not receive these teaching aids.
