In today's knowledge-based and rapidly changing society, developing students' critical thinking skills in instruction is a vital concern in almost all science curricula. To acquire meaningful learning, learners need to develop skills in choosing suitable information, gauging the integrity of information, and crafting sound decisions. With this,…

Recent research syntheses have identified several potentially high-leverage teaching strategies for improving low-attaining secondary school students' learning of mathematics. These strategies include the structured use of representations and manipulatives and an emphasis on derived facts and estimation. This paper reports on 70 semi-structured…

This study investigates how self-efficacy and motivation predict students' science literacy and career expectations above and beyond their socioeconomic status. A structural equation model built on self-determination theory and self-efficacy was examined using PISA 2015 data from Finland and Japan. The study sample is 5882 and 6647 15-year-old…

Background: There is a gap in the literature regarding data on sexting among youth under the age of 16 whereas the problems related to this practice could affect them more because of their ongoing development. This study aims to determine the prevalence rate and characteristics of sending one's own sexually related image among middle-school teens.…

As highlighted in the literature, one of the main difficulties in mathematics is the management of different semiotic representations. This difficulty occurs in verticals throughout schooling and is often an obstacle to the proper learning process of mathematics. The present study aims to investigate the different facets of these difficulties with…

Purpose: Worldwide, schools implement social-emotional learning programs to enhance students' social-emotional skills. Although parents play an essential role in teaching these skills, knowledge about their perspectives on social-emotional learning is limited. In providing insight into the perspectives of parents from adolescent students this…

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.…

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…

Longitudinal associations between popularity, peer acceptance, and academic performance were examined in Chinese 7th (n = 880; 400 girls; M[subscript age = 13.33, SD = 0.64) and 10th grade (n = 646; 342 girls; M[subscript age] = 16.76, SD = 0.75) adolescents across three academic years. Growth curve analysis revealed parallel changes in popularity…

The study analyzes the impact of specific learning activities that are using student-centered methods, focusing on various aspects of Iceland. In the sixth grade, the lesson on the topic "Iceland" features an activity called "Famous Icelandic Places," based on a teaching game. In the ninth grade, an activity related to glacial…

Anonymous questionnaires are frequently used in research with adolescents in order to obtain sincere answers about sensitive topics. Most longitudinal studies include self-generated identification codes (SGICs) to match information. Typical elements include a combination of letters and digits from personal data. However, these data may make the…

This study explores lower secondary school teachers' arguments and perceptions for using a 26-point grading scale (26-PGS), and gender differences in assessment practice. An explanatory sequential design was conducted. First, teachers (n = 6) assessment of students' text (n = 182) was analysed. In the subsequent phase, an open-ended questionnaire…

Academic self-concept and achievement have been found to be reciprocally related across time. However, existing research has focused on self-concept and achievement scores that have been averaged over long time-periods. For the first time, the present study examined intraindividual (within-person) relations between momentary (state) self-concept…

The following survey study uses a quantitative research design to investigate motivational and affective aspects of students (aged 14-17) in a mathematical workshop on graph theory. Motivational and affective aspects are related to heart rate measurement (using the digital medium of a pulse watch) in mathematical knowledge development processes in…

Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…
