Successful early mathematical development is vital to children's later education, employment, and wellbeing outcomes. However, established measurement tools are infrequently used to (i) assess children's mathematical skills and (ii) identify children with or at-risk of mathematical learning difficulties. In response, this pre-registered systematic…

This meta-analysis examined the validity of an alternative to traditional assessments called the Wonderlic which is a brief measure of general mental ability. Our results showed significant, positive correlations between Wonderlic scores and academic performance in general ([r-bar] = 0.26), between Wonderlic scores and undergraduate GPA in…

The "k"-means clustering method, while widely embraced in college student typology research, is often misunderstood and misapplied. Many researchers regard "k"-means as a near-universal solution for uncovering homogeneous student groups, believing its success hinges primarily on the selection of an appropriate "k."…

The current study reviewed the practice and application of social validity assessments in single-case design (SCD) studies within the field of school psychology. Social validity refers to the acceptability of intervention or program goals, procedures, and outcomes to educators, families, and students. Understanding the ways social validity is…

Purpose: The goal of the current study was to conduct a substantive validity review of four autism knowledge assessments with prior psychometric support (Gillespie-Lynch in J Autism and Dev Disord 45(8):2553-2566, 2015; Harrison in J Autism and Dev Disord 47(10):3281-3295, 2017; McClain in J Autism and Dev Disord 50(3):998-1006, 2020; McMahon…

This systematic review aims to provide a complementary to existing synopses of the state-of-the-art of mathematics education research on "proof" and "proving" in both school and university mathematics. As an organizing framework, we used Cohen et al.'s triadic conceptualization of instruction, which draws attention not only to…

Research on classroom motivational climates and microclimates--students' shared and idiosyncratic perceptions of motivational classroom features--demonstrates their importance for fostering adaptive motivational and achievement-related outcomes. However, a lack of coherent theoretical guidance about the nature of students' classroom climate…

We aimed to evaluate the performance of supervised machine learning algorithms in predicting articles relevant for full-text review in a systematic review. Overall, 16,430 manually screened titles/abstracts, including 861 references identified relevant for full-text review were used for the analysis. Of these, 40% (n = 6573) were sub-divided for…

The purpose of this meta-analysis was to evaluate the potential of two silent reading fluency measures as indicators of reading competence. Specifically, we analyzed score differences between the "Test of Silent Contextual Reading Fluency" (TOSCRF), the "Test of Silent Word Reading Fluency" (TOSWRF), and other standardized…

To determine the effects of explicit instruction (EI) and potential moderators in second/foreign language (L2) teaching, this study meta-analyzed 28 primary reports (a total of 67 unique samples, N = 3754). The main results show that EI was significantly effective in facilitating L2 development, with effect sizes ranging from moderate to large…

Dynamic assessments (DAs) of word reading skills demonstrate strong criterion reference validity with word reading measures (WRMs). However, DAs vary in the skills they assess, their format and administration method, and the type of words and symbols used in test items. These characteristics may have implications on assessment validity. To compare…

Active learning is a popular approach to teaching and learning that has gained traction through research on STEM educational improvement. There have been numerous university- and national/international-level efforts focused on transitioning courses from the lecture method to active learning. However, despite these large-scale changes, the active…

Introduction: The What Works Clearinghouse (WWC) reviews rigorous research on educational interventions with a goal of identifying "what works" and making that information accessible to educators and policymakers. In rating the quality of causal research, the WWC has historically prioritized internal validity over external validity. One…

Background: Mental health (MH) problems are more common in people with intellectual disabilities (ID), yet under-diagnosis persists, which may be partly due to a lack of appropriate assessment tools. This study presents a systematic review of instruments used to assess MH problems in Spanish-speaking adults with ID. Method: Following PRISMA…

It is a necessity for a researcher to ensure that the validity and reliability of the study is met to prove a discovery. However, there are still qualitative researchers who are still reckless and do not emphasize the concept of validity and reliability when designing, collecting, and analysing the research findings. The quality of a qualitative…
