Online Problem Sets Enhance Active Learning

Abstract. This paper discusses the author‘s experience with using the LON-CAPA learning system for on-line problem set delivery in six engineering, engineering technology, and landscape architecture courses offered at the University of Delaware over more than 13 years. LON-CAPA (web site: http://www.lon-capa.org/) is free, open-source, course-management software developed and supported by Michigan State University. LON-CAPA includes sophisticated testing and assessment components that provide a variety of formats for homework (HW) problems that are computer-graded and submitted by students on-line. The unique features of the online problem set system can be used to enhance active learning.

Courses included surveying, soil mechanics, stormwater management, and site engineering. This paper focuses on the pedagogical advantages the author has identified of using online problem sets based on his experience with use of the LON-CAPA system in his courses since fall of 2002. Advantages include: significant reduction in if not elimination of cheating, better more individualized student/instructor interaction, and increased motivation for students to engage actively with the material and complete assignments successfully. Online problem set characteristics promote these results through immediate feedback, support of problem-based and collaborative learning, and use of mastery-based grading.
