Abstract

JITAR online modules to improve math preparation of engineering students: Preliminary results There are several factors that influence student retention and success in engineering, themost important being mathematical competency, but there is well documented knowledge gap inthe preparation of engineering undergraduates. Engineering programs typically enforceprerequisites to guarantee a certain level of mathematics proficiency before the students canenroll in engineering classes. Due to several factors this sequence is not completely effective atpreparing engineering students and engineering educators are challenged with students at greatlyvarying mathematical skill levels, while needing to quickly bring all students up to the samemathematical mastery level at appropriate points during a semester. While the traditional modelof integrating engineering applications into the mathematics courses and later reviewing thoseconcepts in engineering courses has benefited the math preparation of the engineering students, itdoes not completely address the mathematical knowledge gap of engineering students due to its"one size fits all" approach to the problem (Manseur, Leta, & Manseur, 2010). To address this problem, our team of mathematics and engineering instructors designed ateaching e-tool called Just-In-Time Assessment and Review (JITAR). It is delivered as an on-line system consisting of a series of individualized mathematics modules, to be inserted withinengineering courses at strategic points in the semester, prior to students needing those math skillsin the engineering course. JITAR assesses the mathematical competency level of the individualstudent and provides formative individualized learning opportunities in time for the students tobe successful in applying the necessary mathematics to the new engineering course material.WeBWorK, an open source on-line homework system, was chosen as the appropriate softwarefor the delivery of these modules. The structure of the modules relies heavily on the fact that theassessment and review content needs to be generated based on individual student’s performance.Therefore the team created a new type of WeBWorK assignment to support the desiredpresentation and flow of the module integrating assessment and e-learning assistance by offeringa customized learning path to students. The first JITAR module has been developed for Complex Numbers and ComplexFunctions and implemented in Linear Systems for Biomedical Engineers course which is a juniorlevel required course in the Biomedical Engineering curriculum. The module has been createdas an application in WeBWorK which will allow any engineering course instructor to import andadopt easily. In this paper, we will present the preliminary results from the first yearimplementation of JITAR modules. WeBWork has extensive student progress data captureability which will help us with direct assessment of the module. Student surveys given after thecompletion of the modules will give us the indirect assessment results. We will also compare theperformance of students on selected topics with or without the module in Linear Systems forBiomedical Engineers course.This project is currently funded by National Science Foundation
