WeBWorK is an open-source online homework system originally created for mathematical disciplines and now used in a wide variety of courses involving numerical problems. With the system instructors can assign homework sets of problems to students. These problems can take in a variety of student inputs with the most commonly used being mathematical formulas or numerical answers. Using variables, the system can generate individualized problems for each students. These problems are stored on the instructor’s course in WeBWork, but can also be shared with other instructors running the WeBWorK system through the Open Problem Library.
WeBWorK was implemented in a second year Material and Energy Balances course with 190 students enrolled. In previous years homework sets were done using paper submissions. Analysis was done on the shift of these homework sets from paper to WeBWorK. This analysis includes instructor and teaching assistant time and effort put into creating and administering the two types of homework. Student usage of the system was monitored including number of attempts and problem completion. Students were also surveyed for their opinion of the system and for elements of the WeBWorK system that they valued of disliked. The results of these analyses are used to inform best practices implementing WeBWorK in a Chemical Engineering classroom.
There are currently number of openly available resources for material and energy balance courses such as online videos and course packages from LearnChemE as well as multiple choice ConceptTests from the AIChE Concept Warehouse. Development of WeBWorK homework problems builds on these existing resources by providing homework problems with a greater variety of input possibilities.
