Abstract

This research was motivated by junior high school students' low mathematical critical thinking ability in Two-Variable Linear Equation Systems (SPLDV), shown by their difficulties interpreting word problems, constructing mathematical models, and drawing logical conclusions. This study aims to describe the change in students' mathematical critical thinking ability on SPLDV after learning with the Teams Games Tournament (TGT) model assisted by Wordwall. Using a quantitative pre-experimental approach with a One Group Pretest-Posttest Design, the sample comprised 28 eighth-grade students (class VIII-B) of SMP Negeri 1 Sipispis, selected through purposive sampling. The instrument consisted of five essay items, one for each of five critical thinking indicators, scored with a 0–4 rubric. A pilot test with 25 students showed item-total correlations of 0.59–0.85 (rtable = 0.396) and a Cronbach's Alpha of 0.76. Data were analyzed using normality tests on the difference scores, a paired-samples t-test (α = 0.05), effect size, and normalized gain. The mean score increased from 36.61 (pre-test) to 75.71 (post-test); the mean difference of 39.11 points was statistically significant (95% CI [33.33, 44.89]; t(27) = 13.88, p < 0.001; Cohen's dz = 2.62), with a normalized gain of 0.62 (moderate), and all 28 students improved. Scores rose on all five indicators. Because the design had no control group, the improvement cannot be attributed solely to the treatment and should be confirmed with a quasi-experimental design.
