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)…

Structured teacher collaboration has considerable potential to support teachers' professional learning. The current article focuses on what characterises teachers' decision-making processes during teamwork. Video recordings of teacher team meetings form the empirical basis for the research. Interaction analysis is employed to analyse under what…

This study examined "backward transfer," which we define as how students' ways of reasoning about previously encountered concepts are modified when learning about new concepts. We examined the backward transfer produced when students learned about quadratic functions. We were specifically interested in how backward transfer may vary for…

Background: Suicide is the second leading cause of death among youth aged 10-24 years in Washington State. Population-based data on suicidality among sexually and gender diverse (SGD) youth and modifiable protective factors from Washington are limited. Methods: Using data from the 2021 Washington Healthy Youth Survey, a statewide,…

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…

Researchers tend to use oral- and silent-reading fluency measures interchangeably and to generalize research findings across reading modes, especially from oral to silent reading. In this study, we sought to examine if oral and silent word-reading fluency rely on the same cognitive-linguistic skills. Three hundred and forty-five Greek children (80…

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…

A controversial, equity-focused mathematics reform in the San Francisco Unified School District (SFUSD) featured delaying Algebra I until ninth grade for all students. This study examines student-level longitudinal data on mathematics course-taking across successive cohorts of SFUSD students who spanned the reform's implementation. We observe…

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…

This paper evaluates a Hungarian gifted education programme aimed at providing equal opportunities for students with social and economic disadvantages. In the context of a retrospective study, the differences in academic success and learning pathways were examined in a cohort comprising a group that participated in the programme and a group that…

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…
