Background: YouTube is widely used for learning about scientific issues in and out of school. However, much of the scientific information on YouTube is inaccurate. Prior studies have mostly focused on how students evaluate textual online information sources and have not yet systematically examined how they evaluate authentic scientific YouTube…

One of the major purposes of this study is to investigate the potential impact of gender and information and computer technology (ICT) resources on students' computational thinking (CT) competencies. To this end, the Computational Thinking Test for Junior High Students (CTT-JH) was developed and validated. Research participants included 437 junior…

This study was conducted to develop a valid and reliable measurement tool that can identify middle school students' self-regulation skills. Firstly, the literature was utilized in the development of the measurement tool. The form was finalized with the support of the opinions of different experts and a trial application. Then, the form was…

Providing adequate proof is one essential mathematical method, but it is a difficult task for many school-age students. While previous studies have revealed the cognitive factors of proving the proof, the function of affective factors and learning engagement has been largely unexplored. This study examined the effects and processes associated with…

This study aimed to develop a measurement tool to determine the level of acceptance and use of interactive digital e-books by secondary school students. With the acceptance scale towards interactive e-books of secondary school students (IE-BAS), it is envisaged to determine both in-class activities and activity efficiency. The technology…

The purpose of this study is to adapt the "Computer Programming Self-Efficacy Scale for Computer Literacy Education (CPSES)" developed by Tsai et al. (2019) into Turkish for middle school students and to develop a valid and reliable measurement tool. The participants of the study consisted of 348 eighth grade students. In order to test…

Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

The aim of this research is to develop a measurement instrument that is valid and reliable, called the Middle School-Life Science Concept Inventory (MS-LSCI), for the purpose of measuring the life science conceptual understanding of middle school-level students. Although there are several existing concept inventories related to biology concepts…

Previous research making claims about students' proving capabilities usually only explored one modality (e.g. oral or written arguments). This study compares the written and oral representations of eighth-grade students' mathematical arguments to determine whether the two modalities portray similar understandings. We replicate Stylianides' (2019)…

In this study, a valid and reliable scale was developed to measure parents' perceptions of their children's social development in physical education classes. In the first part of the research, the relevant literature reviewed and student-parent interviews were held. As a result of the data obtained from the interviews, a 30-item draft scale was…

The study aimed to test the psychometric properties of a Portuguese adaptation of the "Adolescent Students' Basic Psychological Needs at School Scale" (ASBPNSS). For this, we used data from a sample of eighth graders (N = 1648; M[[subscript age] = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the…

This study evaluated the forecasting accuracy of trend estimation methods applied to time-series data from computer adaptive tests (CATs). Data were collected roughly once a month over the course of a school year. We evaluated the forecasting accuracy of two regression-based growth estimation methods (ordinary least squares and Theil-Sen). The…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

This study sought to develop an Academic School Climate Scale measuring students' perceptions of the learning environments at their schools. With a pilot sample of 1,265 students and validation sample of 14,773 students in Grades 4-12 in schools across the U.S., results of EFA and CFA supported a bifactor model with a general factor and three…

Effectively evaluating the credibility and accuracy of multiple sources is critical for college readiness. We developed 24 source evaluation tasks spanning four predicted difficulty levels of a hypothesized learning progression (LP) and piloted these tasks to evaluate the utility of an LP-based approach to designing formative literacy assessments.…
