The study focused on effect of Quizziz method on mathematics test performance of junior secondary school students in Port Harcourt metropolis. The study used quasi-experimental study to sample. The population of the study consisted of over 3,250 junior secondary school students in Port Harcourt metropolis. Participants in the study included 100 junior secondary school students from two lower UBE schools in the metropolis. Participants were randomly assigned to experimental (Quizizz group) and control groups. The instrument used in the study was the Mathematics Achievement Test (MAT). The instrument was validated by test experts while Cronbach Alpha method was used in determining a reliability index of 0.87. Experimental procedures involved a pre-test assessment which was administered to both the experimental and control. The experimental group received mathematics instruction using Quizizz for a period of three weeks. After the treatment, a post-test assessment was administered to both groups. Ethical Considerations included an informed consent from participants and parents or guardians. They were also ensured of confidentiality and anonymity while the study was also approved by an independent Research and Ethics expert. As stated earlier, the study lasted for a period of three weeks. The researchers collaborated with the classroom teachers which used the computer lab setting. After the posttest, data collected were analized using paired sample t-test and independent t-test. result showed that
