Students' academic performance is determined by certain intrinsic and extrinsic attributes, which are shrouded in their stages of development. The focus of this study was, therefore, to analyse factors influencing students' performance in two randomly selected junior secondary schools in Maun, Botswana. Guided by McClelland's motivational theory,…

While loneliness for short periods of time is normal, prolonged loneliness has severe health risks. This study aims to discover what loneliness trajectories can be found in a cohort of adolescents, how belongingness to different groups may be associated with these trajectories, and the mental, physical, and academic consequences of these…

The study aims to investigate how confidence in mathematics/science, amount of books in the home, gender, whether a student likes being in school, and computer software predicted mathematics and science achievements of students in the Trends in International Mathematics and Science Study (TIMSS) 2019. The sample of the study consisted of…

This paper presents findings from a pre-post study on pre-service teachers' beliefs about multilingualism and language use. A full cohort of pre-service middle school teachers in Germany (n = 259) was surveyed before and after completing a compulsory module on multilingualism using a validated instrument that captures participants' beliefs about…

The purpose of this study was to examine the relationships among homework time, homework frequency, and learning achievements of Taiwanese students. Applying a 2-level hierarchical linear modeling on the TIMSS 2007 and 2011 data, our findings were as follows: (1) Within the context of TIMSS 2007 and 2011 students, the frequency of mathematics…

The overall aim of this study was to examine the different self-reported students' socioeconomic status (SES) measures in the Trends in Mathematics and Science Study (TIMSS) in comparison to national SES measures obtained from Swedish official registers. A further aim was to determine if the same conclusions could be drawn if different student…

The aim of the present study was to examine the kinds of developmental profiles of arithmetic fluency skills that can be identified across Grades 1-9 (ages 7-16) in a large Finnish sample (n = 2,518). The study also examined whether membership in the developmental profiles could be predicted using a comprehensive set of kindergarten-age factors,…

Background: Food insecurity is characterized by limited access to adequate food due to a lack of money or resources (eg, lack of transportation to obtain food). School aged children who are experiencing food insecurity are at greater risk for poor academic outcomes, but previous studies have not examined the effects of food insecurity on specific…

Objective: This longitudinal study investigated the predictors of and changes in psychological trauma during the COVID-19 pandemic. Method: Participants included 236 adolescents (130 males; M age = 16.74 years in spring 2020; 49.6% diagnosed with attention-deficit hyperactivity disorder; 16.1% diagnosed with an anxiety or depressive disorder) in…

This study explores how various measures of home learning environment (HLE) collected at different ages are related to each other and explores associations when the effects of significant child and family characteristics are controlled for. Different age-appropriate measures of the HLE were constructed at ages 3, 7, 11, and 14. The measures were…

The present study examined students' attitudes toward science and associated constructs, based on the theories of reasoned action and planned behavior, and explored relationships between individual and school-related variables common to the research literature. Responses from 1,291 students in Grades 5 through 10 were collected using the 30-item…

This study investigated whether there are significant differences between reading achievements of 15-year-old students and starting age for preschool and socioeconomic factors according to the results from the PISA 2015 and 2018. The quantitative results show that there is a clear and statistically significant difference between reading test…

In this study, the effects of some student (e.g., gender, bullying, etc.) and school variables (e.g., emphasis on academic achievement, clarity of teaching, etc.) on the TIMSS 2015 science and mathematics achievement of eighth grade students in Türkiye were examined by controlling for the socioeconomic status of the students at the student and…

This study examined interparental conflict as a linear and curvilinear predictor of subsequent changes in adolescents' negative emotional reactivity and cortisol functioning during family conflict and, in turn, their psychological difficulties. In addition, adolescents' negative emotional reactivity and cortisol functioning during family conflict…
