Leveraging Simulation Tools to Deliver Ill-Structured Problems in Statics and Mechanics of Materials: Initial ResultsThis paper summarizes the initial results from an NSF TUES project in which new coursemodules that vertically integrate Statics and Mechanics of Materials are being developed,implemented, and assessed. These initial results are from the Fall 2012 semester in which thenew modules were newly introduced into three sections of the Statics course.The new modules engage students in ill-structured problems, i.e., problems which requirestudents to evaluate or provide assumptions, compare several “what if” scenarios, or otherwiseperform design or design-related tasks. The modules will simultaneously stretch the content ofthe Statics course to include some topics that are not traditionally covered, such as redundancy,structural displacements, and small displacement approximation. Simulation tools – primarilycustom designed templates for Excel, NX Finite Element Analysis, and SAP2000 – areintroduced as “sophisticated calculators” that enable students to efficiently solve analyticalquestions within the modules that would be tedious or intractable by hand calculation.To facilitate long term assessment of the modules, the module content is oriented toward thediscipline of structural engineering. While the interventions of this project will occurconsecutively in Statics and Mechanics of Materials I, student performance will continue to bemeasured in subsequent courses Mechanics of Materials II and Structural Analysis.The paper will be organized to address the following components of the project in detail: A summary of the Delphi process used to develop content of the modules; A description of each module, including its topical content, simulation platform, and location within the Statics schedule; A discussion of the philosophy to introduce simulation tools to entry level students who have not yet learned the underlying numerical or modeling theory, and the development of customized templates and user interfaces to simplify students’ use of simulation software; A preview of how the modules will be further developed and continued during Mechanics of Materials I; A summary of the assessment results after the Fall 2012 semester, including performance on the modules, exams, the Concept Assessment Tool for Statics (CATS) concept inventory, and student interviews. We expect that the exposure to these modules and the students’ corresponding learning activities will accelerate the development of their mastery of mechanics and overall expertise in engineering.
