In this article, the authors address some of the scientific challenges associated with using observation as a research method. The authors ask how researchers contextualise and understand observation in terms of its theoretical underpinnings and how it is conducted. Using a vignette in the kindergarten context, the authors explore how observation…

Experimental studies have a considerable impact on the educational policies and practices of many countries. In Turkey, policymakers are planning to initiate a STEM education reform in K-12 schools based on experimental studies.

In experimental studies, researchers are often interested in secondary research questions that explore important aspects of main findings, such as whether or not program effects vary according to the level of fidelity in which the program has been implemented; or according to the dosage received by individuals participated in the program. In this…

The primary purpose of the study was to investigate the extent to which students who entered kindergarten are deficient in reading readiness skills; to determine the outcome of parental involvement in children's early education; and to gain a clear, holistic understanding of the research problem. The research methodology selected for this study…

This paper introduces an empirical strategy to estimate dynamic treatment effects in randomized trials that provide treatment in multiple stages and in which various noncompliance problems arise such as attrition and selective transitions between treatment and control groups. Our approach is applied to the highly influential four year randomized…
