Abstract:
This research aimed to; 1) study research characteristics on English reading skills development, 2) synthesize research studies related to the English reading skills development, and 3) study mediating effects in the structural equation model and validate the model. The sample was 57 research graduate of which 7 were correlational studies and 50 were experimental studies, published during 2002 to 2018 by 21 universities. The research results comprised totaling of 225 standard indices. The quantitative data analysis using meta-analysis, and the model was validated using LISREL. The results were as follows:
1. There were 19 variables in this research including year, institution, researcher dapartment, research objective, research type, research hypothesis, research design, sample resources, sample education level, sample selection, independent variable type, independent variable measuring type, independent variable reliability type, dependent variable measuring type, dependent variable validity type, dependent variable reliability type and data analysis type.
2. The mean of effect size on English reading skills development was .447, the standard deviation was .282. The 57 research graduate in English reading skills development results different from the overall research characteristics except sample resources. The multiple regression analysis showed that all dummy variables were significantly different. All variables could explain variance of standard indices at 60.8%.
The results of multilevel analysis showed that overall variance of the standard indices was 0.184 which drawn from the variance among the reports at .177, and drawn from the variance within the reports at .007.
3. The results of the analysis of model fit of the structural equation model of variables that influenced the English reading skills fitted very well with the empirical data (X2 = 54.77, df = 47, p = .20, X2/ df = 1.165, GFI = 1.00, AGFI = 1.00, NFI = 1.00, NNFI = 1.00, RMSEA = .007, SRMR = .019). The variables in the whole model could 41% account for the variance of English reading skills development. The model total effect from readind engagement transfered to English reading skills was .64, classroom instruction and teaching was .62, motivation in reading was .37 and cognition in reading was .35. All mediating effects were significantly at .01 level.
