This paper informs users of data collected in international large-scale assessments (ILSA), by presenting argumentsunderlining the importance of considering two design features employed in these studies. We examine a commonmisconception stating that the uncertainty arising from the assessment design is negligible compared with that arisingfrom the…

The adoption of the maker-centered method is gaining popularity in K-12 school curricula. However, a unified consensus on its effectiveness in enhancing K-12 students' learning outcomes remains elusive. Therefore, the purpose of this meta-analysis was to synthesize the findings on the overall effects of the maker-centered learning method on K-12…

Children should be heard on matters that impact their educational lives. However, meaningfully engaging autistic children can be difficult for researchers and policymakers. Therefore, this systematic review aimed to summarise methods used to gather the views of autistic children on their primary educational experiences. Database searches…

Intensive academic interventions help address the learning difficulties of students with specific learning disabilities (SLDs). Challenging behaviors exhibited during instruction can have a negative impact on the overall effectiveness of an academic intervention. In addition to academic interventions, students with SLD may benefit from behavioral…

Traditionally, cluster randomized controlled trials are analyzed with the average intervention effect of interest. However, in populations that contain higher degrees of heterogeneity or variation may differ across different values of a covariate, which may not be optimal. Within education and social science contexts, exploring the variation in…

It can be suggested that pre-service primary school teachers' sense of belonging to science may be influential to their professionalization within university-based teacher education programs, which intend to prepare them for teaching natural sciences in primary school. Nevertheless, because only few studies have examined teachers' sense of…

This paper reports the findings of the second year of a four-year empirical research project. Its aim is to modify 'step-by-step' instructions for practical activities in a way that may enable the development of experimental design skills among junior high school learners. Each school year pupils spend six lessons doing practical activities using…

In this paper, we critically examine the way in which scholars have traditionally defined and problematized attrition. Through a series of examples of large-scale intervention impact studies, we share insights about the sources and consequences of attrition that expand our notion of how and why attrition occurs. We also discuss potential steps for…

Yinyang philosophy encompasses an essential understanding of the mechanism and laws of nature, cosmos, and human society in Chinese culture, and reaches to many other parts of Asia and around the world. The purpose of this article is to explore how yinyang philosophy can serve as a philosophical underpinning of mixed methods research (MMR). In…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

Astronomy education is essential for STEM education in primary schools, and integrating engineering design-based science education enhances student engagement and achievement in the field of space science. Integrating engineering design into science education is essential for students to excel in astronomy and to meet the requirements of…

Purpose: Systematic reviews of literature are routinely conducted to identify practices that are effective in addressing educational and clinical problems. One complication, however, is how best to combine data from both group experimental design (GED) studies and single-case experimental design (SCED) studies. Percent of Goal Obtained (PoGO) has…

This study synthesized 14 published and unpublished group design and single-case design studies on bullying interventions for individuals with disabilities. The specific objectives were to examine the general characteristics and design qualities of the studies, quantify the magnitude of the intervention effects, and identify potential moderating…

Recently developed randomized-test procedures for two independent-samples single-case designs are presented and applied to a memory-strategy intervention study with eight underperforming students from low SES backgrounds. Research design aspects, data-analysis features, and various output measures are provided to demonstrate the potential utility…
