Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

A growing emphasis on computational thinking worldwide necessitates student proficiency in creating algorithms. Focusing on the use of counterexamples for developing student-invented algorithms, I reanalyze two pieces of data from previously published research, pertaining to two different cases of students' algorithmatizing activity. In both…

One main obstacle for instructors in inviting students to design knowledge construction is the tension between prioritizing students' ideas and maintaining the scientific validity of the activity. In this study, as a way of supporting students in shaping their own knowledge construction, the establishment of an audience for knowledge was enacted…

As artificial intelligence (AI) becomes more prevalent, so does the interest in AI ethics. To address issues related to AI ethics, many government agencies, non-governmental organizations (NGOs), and corporations have published AI ethics guidelines. However, only a few test instruments have been developed to assess students' attitudes toward AI…

This study reviews the French examination of the College Scholastic Ability Test (CSAT), the most influential and highest-stakes test in Korea. The CSAT score has considerable influence on university admissions, and admission to a highly ranked university is generally a prerequisite for socioeconomic success. From this perspective, the…

Based on the dichotomous classroom goal structure model and TARGET framework, this study developed and validated a new Dichotomous Classroom Goal Structure Questionnaire (DCGSQ). A total of 339 seventh-grade students in Beijing completed the two-phase survey in Study 1. Exploratory factor analysis and reliability analysis were used to assess the…

Digital competence is among the basic key competences for digital learning and employability. For this reason, its acquisition and development should be on the agenda of higher education institutions (HEIs) who wish to prepare their students to thrive in an ever faster evolving digital labour market. However, the existence of a valid instrument…

"Digital native," the term ubiquitously used to describe contemporary learners, is fraught with debate over its meaning and measurement. The Digital Natives Assessment Scale (DNAS) was developed and validated to measure digital nativeness. This study extends the DNAS validation discussion with data from 178 participants in three teacher…

We present action research of a problem posed as part of a multi-participant national (Israeli) test checking the mathematical knowledge of high school students at the ages of 16-17, where some of those who solved this problem made an error by using the converse to a well-known theorem, where the converse is not true. In order to examine the…

The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

Item analysis is performed by developers as an integral part of the scale development process. Thus, items are excluded from the scale depending on the item analysis prior to the factor analysis. Existing item discrimination indices are calculated based on correlation, yet items with different response patterns are likely to have a similar item…

A common observation in Transformative Learning (TL) literature is the scarcity of ways to gauge the extent of personal transformation. This is despite a recorded history of more than four decades and the existence of multiple schools of thought in TL. Also, there has been insufficient exploration of the personal transformation of profession…

This article reports on the implementation of a formative assessment tool (the Writing Engagement Scale, or WES) in grades 3-5 in schools in the United States. We used confirmatory factor analysis (CFA) to collect validity evidence for the WES for our population. Results demonstrated acceptable validity and reliability. In addition, survey results…

The current study aims to explore the impact of the two-column format in writing simple mathematical arguments. That is to say, a structured method of presenting a mathematical proof or argument by using a tabular layout with two columns. The underlying goal of the research reported in this paper is to inform understanding of how to effectively…

A lack of understanding of statistics, and being unable to apply its techniques, not only has a negative impact on the pass rates of students studying introductory statistics, but also affects the potential usefulness of these students when they enter the marketplace. I report here a novel scale developed to measure various factors that may be…
