Until now, the conventional approach using two distinct groups, experimental and control, continues to dominate research, especially education research. Researchers, particularly those who are active in this domain, readily recognise this pattern when surveying literature. This article explores the use of the Solomon four-group design as a…

Pregnancy is a frequently applied exclusion criteria for many forms of research. Common justifications for this exclusion include the potential for teratogenicity, as well as the potential for physiologic changes in pregnancy to impact the research itself. The systematic exclusion of pregnant persons from clinical studies has created a significant…

Many interventions in education occur in settings where treatments are applied to groups. For example, a reading intervention may be implemented for all students in some schools and withheld from students in other schools. When such treatments are nonrandomly allocated, outcomes across the treated and control groups may differ due to the treatment…

This study examined the treatment efficacy of "PEERS"® (Program for the Education and Enrichment of Relational Skills) among Chinese adolescents with autism spectrum disorder (ASD) in Hong Kong. The original "PEERS"® manual was translated into Chinese, and cultural adjustments were made according to a survey among 209 local…

This quantitative study examined the effects of an online synchronous orientation on the final grade of students enrolled in a first-term online class. The multifactor orientation focused on several factors which are thought to contribute to online student success, including organizational skills, goal setting, orientation to the online classroom,…

The purpose of this review was to conduct a meta-analysis of 25 years of mathematics interventions for students with mathematics difficulty or disability in Grades 4 through 12. A search of the literature yielded 25 studies that met the inclusion criteria. Studies were coded to extract important study information (e.g., participant information,…

In this study, through a meta-analysis of 20 studies, it is aimed to compare the effectiveness of various forms of learning methods including creativity based learning, problem based learning, and differentiated instruction on creativity in terms of the academic achievement of students and to find out other study characteristics, related to the…

One of the key trends in learning technology in recent years has been the growing interest in simulations and serious games. Much of the research into simulations and serious games has tended to focus on aspects of fun and engagement rather than on what is happening in the process to cause transferable learning. Much of it has been based on small…

Field experiments in education frequently assign entire groups such as schools to treatment or control conditions. These experiments incorporate sometimes a longitudinal component where for example students are followed over time to assess differences in the average rate of linear change, or rate of acceleration. In this study, we provide methods…

The statistical method "meta-analysis" is perhaps unique as a contribution to empirical inquiry of many types because it arose entirely within the practice of education research. In spite of its origins, meta-analysis has found its widest application and most important contributions in the field of medicine. Contrasting the success of…

Large numbers of qualified students do not apply to and enroll in college. Yet, earning a college degree is one of the primary pathways for economic success and is increasingly required for good jobs and high wages. A number of programs and practices aim to improve college readiness and enrollment, including "Take Stock in Children's®…

The main goal of this paper is to show how Vasily Davydov's powerful ideas about the nature of mathematical thinking and learning can transform the teaching and learning of additive word problem solving. The name Vasily Davydov is well known in the field of mathematics education in Russia. However, the transformative value of Davydov's theoretical…

Content and language integrated learning (CLIL) programmes are mushrooming in many different contexts. However, research has mainly focused on their impact on foreign language learning and to a lesser extent on L1 development, whereas the number of studies undertaken in multilingual contexts in which more than two languages coexist is negligible.…

This paper presents and evaluates a teacher training approach called the cluster-based mentoring programme (CBMP) for the professional development of government primary school teachers in Pakistan. The study sought to find differences in the teaching practices between districts where the CBMP was used (intervention) and control districts where it…
