NumGebra Island Evaluation

The study was guided by the hypothesis that students who use the developed mobile game-based learning application would show greater improvement in number and algebra proficiency compared to students taught through traditional instruction. To examine this, a quasi-experimental design was employed involving two intact classes: one assigned as the experimental group and the other as the control group. Both groups were first administered a pretest to ensure baseline equivalence, confirming that the students started with comparable levels of mathematical proficiency before the intervention. Data were gathered over a seven-week period. The experimental group used the mobile application as part of their learning activities, while the control group received conventional classroom instruction covering the same topics. At the end of the intervention, a posttest identical in structure to the pretest was administered to both groups. The dataset therefore consists of paired pretest and posttest scores for each learner, along with calculated gain scores that represent the improvement from baseline.
