Subclaims¶

q2 i3 Across 76 graduate studies (1989-2004), CLE students showed much higher achievement in language performance than traditional-instruction students, with effect sizes including d = 2.12 (kindergarten), d = 1.95 (Thai model 1), d = 1.51 (Thai model 2), d = 0.60 (Thai model 3), and d = 8.55 (English model 1). → Rattanavich 2015

q2 · i3 · quant-synthesis · r1

Meta-analysis of 76 graduate students' research studies on CLE instruction in Thai and English at kindergarten, primary, and secondary levels during 1989 to 2004, with dependent variables on language performance, attitudes, and personality development. The Thai-language results print "98.30% (d = 2.12)" for kindergarten down to "72.57% (d = 0.60)" for grades five to six; the English program printed percentages and d values range up to d = 8.55.

"98.30% (d = 2.12) for the kindergarten level, 97.44% (d = 1.95) for grades one to two (model 1), 93.45% (d = 1.51) for grades three to four (Model 2), and 72.57% (d = 0.60) for grades five to six (Model 3) in the Thai language program"

Discussion¶

Related Claims¶

• Blind students taught with CLE performed significantly better in Thai language development than traditionally taught students at the .01 level, with one small kindergarten group as an exception — a narrower finding that bears on this claim
• In the large-scale Thai CLE project (2,945 experimental vs 2,397 control students), 73% of control students in the northeast and 74% in the southern provinces scored below the experimental-group mean on Thai communicative performance — a narrower finding that bears on this claim
• The 1987 Surin pilot of the Thai-language CLE program in two poor schools produced significant results in Thai language development and personal developments such as creativity, self-confidence, and responsibility — a narrower finding that bears on this claim
• CLE classes showed more frequent learning behaviors, emotional-intelligence behaviors, and student-centered teacher behaviors than traditional classes, by Chi-Square comparison — related
