Subclaims¶

q3 i? Meta-analysis of model 1-3 average scores on Thai language communicative performance showed 73% of control-group students in the four northeast provinces and 74% in the southern provinces scored lower than the experimental schools' mean. → Rattanavich 2015 q3 i? The evaluation compared an experimental group of 98 teachers with 2,945 students in 44 schools against a control group of 95 teachers with 2,397 students in 47 schools, drawn from matched pairs of schools. → Rattanavich 2015 (2)

q3 · i? · quant-synthesis · r1

Meta-analysis of all results of average scores of models 1, 2, and 3 on Thai language communicative performance (reading, writing, listening, speaking) across the northeast and southern province implementations. The article reports "73% of the stud ents in the control group schools scored lower than the mean score" in the northeast and 74% in the south; no standardized effect size is printed for this comparison.

"73% of the stud ents in the control group schools scored lower than the mean score of the students in the experimental sc hools in the four northeast provinces, and 74% of the students in the control group schools scored lower than the mean score of the students in the experimental group schools in the southern provinces."

q3 · i? · causal · r1

Design of the Rotary-funded five-year project in four northeastern provinces: experimental and control groups of students and teachers were randomly drawn from matched pairs of schools, from both language-problem and non-language problem areas. The article prints "2,945 students in 44 schools" experimental and "2,397 students in 47 sc hools" control.

"the experimental group consisted of 98 teachers (98 classes), with 2,945 students in 44 schools, while the control group consisted of 95 teachers (95 cl asses), with 2,397 students in 47 sc hools."

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
• A meta-analysis of 76 CLE research studies found students taught with CLE models 1-3 in Thai and English achieved at much higher percentages than traditionally taught students, with printed effect sizes from d = 0.60 to d = 8.55 — a broader claim this one bears on
• 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 — related
