Stability and change in students' achievement goals (AGs) are of great relevance for educational research and practice. In two separate meta-analyses, we investigated the rank-order stability (93 studies, 569 effect sizes, 54,736 students), as well as the mean-level change (157 studies, 1,170 effect sizes, 81,464 students) in AGs throughout…

One-hundred and twenty-two undergraduates completed a survey assessing beliefs that WM is a stable trait, or that it is quality that can be improved with skill training. They then read an authentic set of journal articles in a special issue, which discussed whether a program called CogMed is or is not effective in promoting WM functioning.…

This study aimed to provide initial validity and reliability of the "Measure of NDBI Strategy Implementation-Caregiver Change" ("MONSI-CC"), a novel measure that captures changes in caregivers' implementation of NDBI strategies during early intervention. The MONSI-CC was applied to 119 observations of 43 caregiver-child dyads…

The objective of this study was to assess the reliability and minimal detectable change (MDC) of the Styku S100 3-dimensional (3D) scanner. Thirty-three participants completed two visits separated by 1-3 days; at each visit, two scans were performed. Intra-class correlation co-efficients (ICCs) and MDC values based on a 90% confidence interval…

Accurate and consistent reviews of documents describing research studies are essential to valid and generalizable inferences in a meta-analysis. Traditionally a small number of reviewers screen studies using the title, abstract, and possibly the full text to determine a study's eligibility for a meta-analysis. This study explores whether reviewing…

Predictive power of many behavioral measures relies on high test-retest reliability, whereby a measure yields similar data when repeated measure administration occurs at spaced-out intervals. However, major environmental disruptions between measure administration may impact test-retest reliability. The novel coronavirus (COVID-19) pandemic caused…

Promoting positive development may lead to young people's active contributions to their environment through positive attitudes and behaviours. The Climate Change Attitude Survey (15-item version) aims to identify climate change attitudes differences in groups of students and to assess pre- to post-intervention attitude changes. We intended to…

In recent years, mathematical models of decision making, such as the diffusion model, have been endorsed in individual differences research. These models can disentangle different components of the decision process, like processing speed, speed-accuracy trade-offs, and duration of non-decisional processes. The diffusion model estimates individual…

Purpose: Meaningful changes in picture naming responses may be obscured when measuring accuracy instead of quality. A statistic that incorporates information about the severity and nature of impairments may be more sensitive to the effects of treatment. Method: We analyzed data from repeated administrations of a naming test to 72 participants with…

Research on parent-child shared book reading (SBR) has focused primarily on a single reading of a book and on the reading of the text itself. Yet parents often repeatedly read the same book to their child and continue to converse after the book is finished. Using Bruner's dual-landscape model as a theoretical basis, this study explored the…

Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the strength measurement of knee and hip muscles and their ratios. Thirty-five recreational athletes completed quadriceps, hamstring, and hip adductors and…

Plausibility perceptions about climate change influence learner engagement, motivation, and knowledge acquisition, thereby shaping the effectiveness of climate change education. The Plausibility Perception Measure (PPM) was originally developed following the Fourth Assessment Report of the Intergovernmental Panel on Climate Change in 2007. There…

The relationship between "stability" and "change" is a central paradox of administration that pervades all forms of organizing. Evaluation is not unfamiliar with paradoxical objectives and roles, which can result in tensions for evaluators and stakeholders. In this article, paradoxes between stability and change in the…

This study aimed at examining the suitability of questionnaire instruments commonly used in large-scale assessments for measuring non-cognitive school effectiveness criteria. It focused on questions of reliability and validity for capturing changes in students within schools across time and the instruments' sensitivity to school effects. The aim…

The Transtheoretical Model (TTM) conceptualizes change as a process with five identifiable stages. Each stage has psychological characteristics that are manifestations of an underlying continuum of change. Surprisingly few studies have applied the TTM to understand the process involved with academic development. The objective of this study was to…
