9 Confound: there was only one teacher in the Direct Instruction condition (supported by her two teaching assistants) compared with two instructors (and their teaching assistants) who taught in the Interactive Instruction condition (one instructor taught two of the three classes), so the analysis could not separate the effects of the intervention from the effects of the teacher.
10 Complete data were not reported: the WWC could not compute effect sizes.
11 Confound: the researcher taught the two intervention groups but had no or minimal contact with the children in the comparison groups; therefore, the effects of the intervention cannot be separated from the effects of the teacher.
12 Incomparable groups: the intervention and comparison groups cannot be considered equivalent at baseline, even with the use of covariates in the analysis.
