This paper aims to explore the effects of teaching English in content-based instruction (CBI) with social studies, math and science. In particular, the current study looks into three issues related to the effects of content-based instruction: (1) Effect differences of English CBI with social studies, math and science, (2) Effect differences of grade levels and (3) Effect differences of length of CBI. The method hired in the study is meta analysis wherein 16 quantitative comparative effect studies were collected and quantified using its means and standard deviation into average effect size and U3 Percentile to compare the effect with the average control group. The result shows that math and science are stronger than social studies in both linguistic and affective domains. 5th and 6th graders are more effective than 3rd and 4th graders due probably to the English preparedness. The longer the CBI is given the higher the linguistic effect is, however the affective effect moves in opposite direction.
