This study examined the impact of using online math applets (OMAs) on middle school students’ knowledge of quadratic functions, one of the areas where students often have difficulties in their learning (Ellis & Grinstead, 2008). Through using Hiebert and Lefevre’s (1986) framework on knowledge types, the problems are assigned into two categories: “conceptual,” and “procedural.” Participants were forty-two eight grade students, randomly assigned into groups, worked on quadratic functions throughout the online-applets based instruction versus traditional lecture. The pre-and-posttest assessing students’ procedural and conceptual knowledge of quadratic functions were administered and students’ interactions with the OMAs were analyzed. The findings revealed that students using OMAs displayed more improvement in their solutions to the items requiring conceptual knowledge of quadratic functions than the students taking traditional instruction.
