q2 · i? · quant-synthesis · r1

Meta-analysis of earlier JAS studies shown in Table 1 (n=103): study-result optimization 52.83% (56 studies), activity optimization 40.57% (43), science process skill 6.60% (7). The article states JAS implementation "can optimize the study activity (40.57%)".

"The effectiveness of JAS approach has been proved by 52.83% of researchers, with optimizing the study result indicator that been proved by the average result of group test achievement of the students with JAS approach are better, complete, or increased."
