Abstract
This research paper aimed to expound on designing a learning environment based on gamification and its effects on cognitive aspects of computer skills for first-grade intermediate students using a quasi-experimental research design with two groups in focus - an experimental group (n=28) and a control group (n=24). The total sample consisted of 52 students selected cluster-randomly from the first-grade middle school students studying in public intermediate schools in Jeddah. The results showed statistically significant differences at the level a >= 0.05 between the mean scores of the experimental group and the control group in the posttest of the computer achievement test in favor of the experimental group. The study gave ground to using gamification in computer course design at different learning stages in Saudi Arabia.
