The increasing number of research studies in social sciences and education led to an increase in the amount of empirical studies. As a result, it is difficult to draw an overall conclusion with regards to the effectiveness of the studies being conducted. Hence, with ‘meta-analysis’, the researchers and the social scientist or the policy makers would be able to synthesize the information gained from the empirical evidences to support or assist them in decision making and support their findings. This handbook will address the application of meta-analysis using the research on metacognition and reading comprehension as an illustration in answering the research questions common to social science and education. The University of Malaysia Sarawak is pleased to make this publication available to the community of postgraduate students and researchers.
