A Computer-Based Learning Environment About Quadratic Functions with Different Kinds of Feedback: Pilot Study and Research Design

Abstract

Feedback is an essential aspect of computer-based learning environments (CBLE). However, the effect of specific types of feedback on the mathematics performance and self-rating ability of students has not yet been definitively established. To resolve this knowledge gap, we plan to conduct a (quasi-) experimental study with 8th- and 9th-grade students in high schools (Gymnasium) in North Rhine-Westphalia, Germany. The study is going to use a MediaWiki-based CBLE named “Discover Quadratic Functions”. This chapter gives an overview of existing research on CBLE design principles and feedback types. Moreover, the theoretical decisions underlying the design of the CBLE on quadratic functions are presented and explained. Finally, we focus on the results of a qualitative preliminary study, as well as the design of the upcoming main study.
