The present study examined how friends' responses to each other during problem talk predicted depressive symptoms over time. Participants included 271 adolescent friend dyads (69 female and 69 male early adolescent dyads; 72 female and 61 male middle adolescent dyads; 66.4% White and 26.6% Black). The adolescents were observed discussing a problem…

This study was interested in the level of correspondence between high school students' self-perceptions of academic competence and achievement. The objectives were to (a) identify different profiles of students in terms of correspondence between perceptions of general academic competence and achievement in language arts and mathematics, (b)…

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,…

For learners from disadvantaged backgrounds with limited science fair-related skills, knowledge, and community support, investigating the advisability of various ways of arriving at a science fair project topic is needed. This mixed-methods case study with an ex post facto criterion-group design uses questionnaire data and science fair awards…

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…

Theoretically, teacher self-efficacy relates to student outcomes through teaching behavior. However, underlying pathways through which specific teacher self-efficacy facets longitudinally relate to student motivation and emotion in classrooms remain unclear. This study aims to overcome this research gap by investigating whether student- and…

There are several conceptualizations of modeling competencies, including among others on the one hand so-called sub-competencies, which are required to progress from one step of a modeling process to the next, and metacognitive individual and group strategies. However, the relationship between metacognitive strategies and modeling sub-competencies…

In this study of 431 Grade 9 and 10 students, we investigated gender and frequency of practical work as determinants of science students' perceptions of their learning environment and attitudes. We assessed classroom environment with the Science Laboratory Environment Inventory (SLEI) and attitudes with the Students' Adaptive Learning Engagement…

Homophobic and transphobic beliefs that lead to bias-based harassment remain a critical concern for young people in the USA. The aim of the present study was to examine the impact of an inclusive comprehensive sex education program (High School FLASH) on homophobic and transphobic beliefs. Data from this study come from a randomized controlled…

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…

Knowledge Building Communities (KBCs) are principled-based, interactive learning environments designed to scaffold higher levels of student agency and the formulation of goals and questions stemming from students' knowledge-building needs. The design of KBCs is guided by a set of 12 principles that have been examined across hundreds of studies.…

How can we use math to understand--and solve--challenges in our world? In "What We Do When Fairness Fails Us," Moises, Marissa, and Astrud realize that a specialized high school uses a lottery for admission that prevents many qualified students from attending. As they research how lotteries work, they come across videos by Federico…

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.…

One of the negative consequences of bullying in schools is its adverse effect on students' sense of safety. Previous studies yielded mixed results and a nonlinear relationship between bullying and students' sense of safety and pointed to the need for revealing possible mediating and moderating factors in order to better understand this…

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…
