Given the potential for significant changes brought about by chatbots, it is necessary to clarify the mechanisms, relevant research, practical applications, and future development of chatbots in education, while making adequate preparations for their limitations and challenges. However, there are currently few studies that systematically review…

For pre-service teachers to develop learners' number sense, they need have a broad repertoire of non-standard calculation strategies. In this paper, we present an analysis of selected research literature from 2000 to 2022 on pre-service teachers' mental mathematics published in peer-reviewed journals. The results of this brief review indicate that…

Learning analytics includes interventions that will support learning and improve learning environments. Despite the fact that learning analytics is a promising field of study, the lack of empirical evidence on the effects of learning analytics-based interventions has been widely addressed in recent years. In this context, insights validated by…

Student state testing, annual teacher evaluation, and A-to-F campus and school district rating are here. And all of these have real policy implications for every school system. With seven thousand students a day dropping out of the public schools in the United States at a rate of one student every 26 seconds, what might be done to help these…

Some 23 journals in educational psychology and related fields, including two organizational "flagship" journals with circulations over 50,000, now "require" effect size reporting. This paper reviews some of the many effect size choices available to researchers. Effect size measures can be grouped into measures of association strength and measures…

The appropriate use of exploratory factor analysis (EFA) necessitates thoughtful researcher judgment concerning a number of analytic decisions. This paper reviews some of the fundamental decisions necessary to conduct an EFA and examines reporting practice in published research across four journals. In general, insufficient information was given…

Describes the early stages of development of the Campbell Collaboration Social, Psychological, Educational & Criminological Trials Register (C2-SPECTR) to help those preparing and maintaining systematic reviews of experiments in these fields. The register currently contains more than 10,000 records, including more than 300 references to existing…

Most studies of mail survey methodology focus on specific design elements, but several major reviews of research have attempted to synthesize the findings of independent empirical studies. This study examined the review articles for what they have to say about factors influencing response rates and for their methodology. A literature review…

Some of the frustrations inherent in trying to incorporate qualifications of statistical results into meta-analysis are reviewed, and some solutions are proposed to prevent the loss of information in meta-analytic reports. The validity of a meta-analysis depends on several factors, including the: thoroughness of the literature search; selection of…

As performance-based assessments have gained wider use, there are increasing concerns about their dependability. This study is a synthesis of existing studies regarding the reliability or generalizability of performance assessments. The meta-analysis involves summarizing, examining, and evaluating research findings. Articles on the dependability…

There exists an abundance of research on topics relevant to the decisions organizations must take in allocating and developing their resources. This paper addresses the problem of integrating those research results. Data needed for the meta-analysis approach to research integration are sometimes not available in the published literature.…

As a predominant research method, the mail survey has been the subject of a considerable body of research. Several major reviews of research have been published that attempt to synthesize findings of empirical studies and identify techniques that stimulate responses. The review articles are examined, identifying procedures and potential…

H. M. Cooper (1988) has developed a taxonomy that classified literature reviews based on six characteristics: (1) focus of attention; (2) goal of the synthesis; (3) perspective on the literature; (4) coverage of the literature; (5) organization of the perspective; and (6) intended audience. One hundred and three meta-analyses identified from the…

Separate meta-analyses have been completed recently on the effectiveness of computer-based education (CBE) in elementary schools, high schools, colleges, and nontraditional postsecondary institutions. Several conclusions can be drawn from these meta-analyses. First, although CBA has not been uniformly successful in all its guises and at all…

The use of meta-analysis in industrial and organizational psychology has become quite common. Unfortunately, the understanding and research necessary to ensure appropriate application of the technique have not been as widespread. As part of a larger study, a content analysis of meta-analyses from the industrial and organizational psychological…
