Creating up-to-date high quality learning materials requires significant resources many instructors cannot afford, especially when it comes to appealing eLearning materials. Peer creation may help to address this challenge. However, existing concepts of peer learning focus mostly on enhancing active discussion and reflection. Thus far, little to no research has addressed processes of systematically creating modular, re-usable learning materials and evaluated the extent to which these materials can enrich the learning experience. To close this gap, we transferred principles of traditional peer learning onto the creation of self-contained, high quality eLearning materials: Web Based Trainings that served as an interactive script and multiple-choice tests as peer assessments. These learning materials were used in a large-scale Information Systems course. We analyzed user logs, measured learning outcomes by a pre- and post-multiple-choice test (n = 164) and evaluated learner satisfaction by an online questionnaire (n = 128). Results show a significant correlation between usage of the peer created eLearning materials and learning outcomes, as well as satisfaction. The study contributes to the pedagogical research by adapting and evaluating traditional peer learning concepts onto eLearning content creation. To practitioners, it reveals ways of creating high quality eLearning materials in spite of limited resources.
