Systematic review and meta-analysis, one of the effective and widespread techniques in forming research-based and holistic evidences, was widely accepted by researchers. With the evolution of this technique, the approach in assessing quality of primary research has become an important topic in this area. However, except publication bias, research has seldom been conducted to investigate biases deriving from methodological features under the context of research synthesis. The purpose of this paper is to evaluate the moderating effects concerning experimental design, measurement tools, and instructor-as-researcher, while investigation the effects of reciprocal instruction on Chinese reading comprehension across students’ grades. Systematic literature review processes were implemented to search, identify, and collect relevant studies. After few keywords were made in searching Taiwan literature database, a total of 2,437 articles were first retrieved, and followed a two-step literature screening process according to inclusion and exclusion rules, 43 articles were formally adopted. Random effect model was adopted while meta-analyzing findings of the included studies, an overall average effect size of +0.4756 and +0.3969 were obtained separately for immediate and follow-up effect. As to the analysis of moderator effects, the findings showed a significant lower average effect size separately for students in fifth-to-sixth grade, and above middle school ages in comparison to students in third-to-fourth grade while using multiple meta-regression with controlling the impact of experimental design. However, no significant moderating effects were found in measurement tools, and instructor-as-researcher. Finally, suggestions and implications were raised for further research. |
