Improving Student Understanding and Efficiency through Technology Use in the Differential Equations ClassroomAbstractDifferential Equations (ODE) is a traditionally difficult course for students, with solutionprocesses that are often long and tedious. Additionally, the online course management systemsthat students have come to expect in pre-calculus and calculus sequences, along with theiradditional video and other resources, are generally not available. This means that students areheavily dependent on class time to help them understand the material for the course.Traditionally, there is a need to “fast-forward” over the tedious integrations and other basiccalculations that are often required for the solution process, in order to present a useful numberof examples. The author has implemented several strategies to help address these issues in herclassroom, including use of Maple in class and recording lectures on the computer via programssuch as TechSmith’s Camtasia.Our university is a small liberal-arts institute that has a strong emphasis on technology use.Enrollment in the Ordinary Differential Equations class is comprised of mathematics majors andstudents in our dual degree and transfer programs for engineering. A significant portion of thestudents are non-traditional and/or have substantial work obligations that they need to balancewith their coursework. This means that any class time missed by a student is especially difficultto catch up, as their time on campus often does not line up with instructor campus office hours.Maple has been a tool available to our ODE students for several years. Recently, we beganrequiring use of Maple in our Calculus sequence, so students are coming into the ODE coursewith some basic degree of knowledge of how to use Maple to solve algebraic equations, performintegrations, and similar manipulations. This has greatly facilitated more extensive use of theprogram in the ODE course. The author uses a mixture of Maple and traditional board work toset up, graph, and solve traditional differential equations and application problems. Using Maplein the lecture allows the instructor to quickly do required integrations, graphs, and algebraicmanipulations without having to skip steps for the sake of brevity. Traditional board work isdone on a TabletPC, which allows for the entire class lecture to be recorded and distributed to thestudent on the Internet. This enables the student to access the course lecture at any time, whichhas proven useful both for review and students who miss class. This approach is used forasynchronous instruction as well, allowing the instructor to develop targeted tutorials and answerstudent email questions with a more comprehensive explanation than is typically viable.This paper discusses the specifics of the strategies implemented. It will look at studentperformance data from recent semesters and compare against pre-existing data. Survey resultsfrom students outlining perceived usefulness of Maple and class recordings will be presented.Finally, suggestions for scaling the strategies for implementation in larger classes are provided.
