Understanding natural selection requires mentally linking various key concepts and processes.

Our study aimed to investigate the understanding of natural selection and the existence of teleological or other misconceptions…

Background: Early sexual reproductive health (SRH) education is linked to a reduction in risky sexual behaviors. Sexually transmitted infections (STIs) are rising at alarming rates. Risky sexual behaviors, including initiation of sex before age 13, having more than four sexual partners, and lack of use of condoms, increase the chance of infection…

An emerging body of research documents a relationship between sleep quantity and delinquency during adolescence. Absent from this line of research, however, is an evaluation of whether the associations between sleep duration and different forms of delinquency vary across periods of adolescence and sex. The current study aimed to address this gap…

Background: In many countries and regions, such as the United States, Europe and China, a trend has emerged in which students' enthusiasm for STEM is declining. This decline may be related to students' lack of science self-efficacy. An accurate examination of students' science self-efficacy can provide a research foundation for how to cultivate…

This study aimed to extend the literature by examining how bystander intervention (i.e. when a witness to a bullying episodes does something to address the situation) varies with respect to the type of bystander intervention (i.e. direct intervention, emotional intervention, involving an adult, ignore) across victim status (friend, unknown),…

The present study investigates the effect of three neo-Piagetian constructs, namely Formal Reasoning (FR), Field Dependence/Independence (FDI) and Divergence (DIV), as well as the effect of age and gender, on students' portrayed representations of the atomic structure, considering their degree of coherence. For this purpose students'…

Conventional wisdom suggests that parents' educational expectations (how far they expect their children to go) and aspirations (how far they want their children to go) positively impact academic outcomes and benefits from attending high-ability schools. However, here we juxtapose the following: largely positive effects of educational expectations…

Background: The comprehensive school health (CSH) framework has four components: social and physical environment; partnerships and services; teaching and learning; and policy. This study examines associations between CSH and student physical activity (PA). Methods: Using 2015/2016 COMPASS study survey data of 37,397 students (grades 9-12) from 80…

Cyber delinquency in adolescence is a particular area of concern for psychologists owing to its association with several mental health issues and its potential link with offline delinquency.

The tables in this report provide national-level estimates of the extent to which students ages 12-18 enrolled in grades 6-12 experience bullying during school. The tables show how bullying victimization varies by student and school characteristics such as sex, race/ethnicity, grade, household income, region, school locale, school enrollment size,…

A widely used instrument was implemented to ascertain the mathematical modelling competency displayed by a cohort of South African learners in grade 10 and grade 12 of the school mathematics programme in South Africa. The cohort comprised 471 grade 10 and 200 grade 12 learners from schools serving learners from low socio-economic status…

We examined developmental changes in self-esteem from late childhood to late adolescence in African American girls (N = 124), comparing skin tone groups. Girls completed a measure of self-esteem when they were in Grades 5, 7, 10, and 12, and in Grade 12 their skin tone was rated on a 3-point scale (1 = "Light," 2 = "Medium," 3…

Information literacy--i.e. obtaining, evaluating and using information--is a key element of scientific literacy. However, students are frequently equipped with poor information literacy skills--even at university level--as information literacy is often not explicitly taught in schools. Little is known about students' information skills in science…

This study aims to determine the views of students with refugee status who have emigrated to Turkey for various reasons and are continuing their education in secondary and high schools about the Turkish education system.
