In recent years, discussion of the limitations of the standard cross-lagged panel model (CLPM) has increased, and the random intercept cross-lagged panel model (RI-CLPM) has been proposed as an improved approach to modeling. By now, there are some first applications of the model to investigate reciprocal relations in self-concept development.…

This study aims to examine the 9th-grade 2018 physics curriculum according to various criteria. A cross-sectional survey model was used. The sample consists of 36 physics teachers working in various high schools in 12 regions of Turkey in the 2022-2023 academic year. The data of the study were collected via the "9th-grade 2018 physics…

Determining the factors that influence implementation of school-based wellbeing and health programs is essential for achieving desired program effects. Using a convergent mixed-methods, multiple informant design, this study considered factors that influence implementation of health programs for ninth grade students and in what ways implementation…

Background: There exist shared competencies between computational thinking (CT) and mathematics, and these two domains also mutually benefit from various teaching approaches. However, the linkages between mathematics and computational thinking lack robust empirical support, particularly from student-centered learning perspectives. Our study aimed…

The impact of engineering design-based STEM education on 9th-grade high school students' attitudes toward STEM and their problem-solving skills was examined in this study. The subject of factors affecting the heat conduction rate in solids was taught using STEM education. In an experimental design with one group pre-test and post-test, students…

COVID-19 has permeated news since December 2019 and has impacted all areas of life. Despite widespread coverage of COVID-related risks, there is limited understanding of adolescent resilience in Global South contexts (e.g., Africa) and against the backdrop of COVID-19. We, therefore, conducted a qualitative secondary analysis of 79 documents…

Although susceptibility to populist sentiments among adolescents is viewed with concern, research focusing on the nature of populism in youth is still rare. This two-wave study (approx. 10 month) among 9th grade German adolescents (T1: N= 1,205; M[subscript age] = 14.4, SD[subscript age] = 0.6; 52.1% female) examined populist attitudes as a…

Targeted school-based programs seem to be a promising approach to help adolescents in need. Nevertheless, successful implementation and evaluation of such programs is challenging. However, there is limited knowledge about (overcoming) the challenges of implementation and experimental evaluation of school-based programs. The goal of the present…

Background: School bullying is a group phenomenon in which being defended by peer bystanders may buffer against the development of psychological problems in victims. Aims: This registered report examines whether being defended diminished victims' daily mood problems and self-blame, both from a within- and between-person perspective. Materials and…

The following study shows how reparameterizations and constraints of the general linear model can serve to parse quantitative and qualitative aspects of predictors. We demonstrate three different approaches. The study uses data from the High School Longitudinal Study of 2009 on mathematics course-taking and achievement as an example. Results show…

This study investigates the problem-solving strategies employed by ninth-grade students when addressing symbolic and real-world contextual problems involving trigonometric ratios. Conducted with 46 ninth-grade students from a Turkish public high school, this research employed a worksheet consisting of six problems aligned with the Turkish…

In this article, the authors share a unique and unfolding story about a program in Virginia that allows districts to opt into a series of Inquiry Design Model (IDM) performance assessments in place of the state-developed multiple-choice test. In the Rockingham County School District, this initiative was piloted in ninth-grade World Geography…

Over the last fifteen years, student well-being has become of greater concern in school education in Canada and beyond. However, there is very little data available on how well Canadian students are. The study that will be reported on in this paper provides such data, specifically the province of Manitoba. Using the Satisfaction with Life Scale,…

We acknowledge the existing educational inequalities that South Africa faces as a result of differences in developmental and equal educational opportunities. The aim with this study was to investigate the role of non-cognitive learning performance variables that affect the learning performance and success of secondary-school learners. Data were…

This research aimed to develop the training activities of the Jitsuksa process and promote the growth mindset of grade 9 students. The tools used in the study consisted of (1) 80 Jitsuksa training activity plans, (2) a mindset assessment form in a six-level ratio, ten items, and (3) an assessment form of growth mindset behavior. Statistics used…
