To design effective instruction, educators need to know "what" design strategies are generally effective and why these strategies work, based on the mechanisms through which they operate. Experimental comparison studies, which compare one instructional design against another, can generate much needed evidence in support of effective…

Educational researchers often need to construct precise and reliable measurement scales of complex and varied representations such as participants' written work, videoed lesson segments and policy documents. Developing such scales using can be resource-intensive and time-consuming, and the outcomes are not always reliable. Here we present…

Comparative analyses in education science have traditionally focused on the category of geographic location as the comparative unit. However, comparison may involve many other units of analysis, such as culture, politics, curricula, education systems, social phenomena, and other categories of the lives of societies. Still, categories are…

Toward the goal of more rapid knowledge accumulation via better meta-analyses, this article explores statistical approaches intended to increase the precision and comparability of effect sizes from education research. The featured estimate of the proposed approach is a standardized mean difference effect size whose numerator is a mean difference…

The article explains the limited presence of geography in New England higher education as a result of the structure of the region's higher education system. Blending the geography and history of education literatures, it identifies type of control (public vs. private), institution type, urban location, multi-campus university systems, and the weak…

Sound educational policy recommendations require valid estimates of causal effects, but observational studies in physics education research sometimes have loosely specified causal hypotheses. The connections between the observational data and the explicit or implicit causal conclusions are sometimes misstated. The link between the causal…

The NAEA Strategic Vision (2015-2020) affirms that "students of all ages benefit from comprehensive, balanced, and sequential learning in the visual arts, led and taught by qualified teachers who are certified in art education". Art educators will readily agree that art is a crucial part of learning for all students. Yet, they ask how…

Research on learning communities has been largely influenced by the sociocultural turn in educational scholarship approximately three decades ago. Here, we present a wider history of research and practice on learning communities as we revisit this highly generative and central topic in the learning sciences. Using this to frame our perspective, we…

Experimental studies are often employed to test the effectiveness of teaching innovations such as new pedagogy, curriculum, or learning resources. This article offers guidance on good practice in developing research designs, and in drawing conclusions from published reports. Random control trials potentially support the use of statistical…

The aim of this article is to provide practitioners and other nonresearchers a basic understanding of research designs to aid in appropriately interpreting and applying research findings in special education. Research design provides the blueprint for conducting a research study and shapes what kind of knowledge is generated by the study. We…

Short comparative interrupted times series (CITS) designs are increasingly being used in education research to assess the effectiveness of school-level interventions. These designs can be implemented relatively inexpensively, often drawing on publicly available data on aggregate school performance. However, the validity of this approach hinges on…

Visual juxtaposition is inquiry through contrast, facilitated by side-by-side positioning of two images, or images and text. When combined with a theoretical foundation that explores interactions between the material and discursive elements of visual data, juxtaposition creates opportunities for qualitative analysis that are not as readily…

It is a fact that a very low proportion of practising teachers are in the habit of reading ELT-related research papers. The main cause of this neglect is assumed to be that teaching and researching are two distinct forms of activity with no links to connect them. After comparing the concepts of progress and change in research versus teaching, this…

The purpose of this document is to provide information and advice to support states in meeting USED Peer Review Requirements related to demonstrating the comparability of test scores across various devices used for technology-based testing. The document is divided into four main sections. In the first section, we discuss and define the…

The purpose of this paper is to describe best practices in designing and implementing strong quasi-experimental designs (QED) when assessing the effectiveness of policies, programs or practices. The paper first discusses the issues researchers face when choosing to conduct a QED, as opposed to a more rigorous randomized controlled trial design.…
