Globally girls' performance in mathematics has improved over the years as measured by TIMSS results. Inconsistency in mathematics performance of boys and girls is still an area of great concern. This study examines the relationship between mathematics achievement and gender of South African Grade 9 learners from TIMSS 2015 data. The data were…

There is growing global concern concerning South African learners' mathematics achievement, with research identifying many factors contributing to poor mathematics achievement, with class size being one of them. When classrooms are overcrowded, this may lead to a stressful environment which can negatively impact the quality of teaching and…

This study examines longitudinal associations among reading skills, math skills and emotional well-being in a Finnish sample (n = 586) followed from the end of comprehensive school (Grade 9, age 15-16) to age 20. In particular, we determine whether the associations between skills and well-being are mediated by self-concept beliefs. In Grade 9, the…

The charter school sector has expanded beyond brick-and-mortar schools to cyber schools, where enrollment grew almost tenfold between 2015 and 2020. While a large literature documents the effects of charter schools on test scores, fewer studies explore impacts on attainment or postsecondary outcomes and there is almost no work exploring the…

The advantages and disadvantages of ability grouping for student achievement are strongly contested, with studies presenting different results. However, much of this research has focused on class-level or subject-level ability grouping. Relatively less research has focused on school-level ability grouping. More importantly, the role of teacher…

We tested the broad generality of a model for predicting 9th-10th grade students' STEM career expectations by age 30, focusing on hard science, mathematics and engineering professions only, known for driving innovation, research and development. The model's predictors included "motivation to learn mathematics", "gender", and…

Due to the fixed school start in Norway in August of the calendar year of students' sixth birthday, the age span in one class is up to twelve months. This can impact academic performance both in the early years and later. In this paper, we investigate the relationship between birth month and mathematics performance by paying attention to the…

The study examines how students in Grade 9 handle conceptual knowledge through the concept of continuity and change in the context of large-scale assessment. The research questions address: (1) what strategies the students use when they use the two parts of the concept concomitantly; and (2) any gender-related differences regarding these…

The challenge of creating reliable technology-based resources for science learning is a perennial challenge in Philippine education, with limited learning materials accessible to all learners. This study is about the development of a videocast embedded with physics education technology (PhET) simulation that served as supplementary learning…

The importance of family background in determining a student's academic achievement has long been acknowledged by researchers. Nonetheless, the effect of schooling on this relationship has also been widely investigated. Some studies have shown that family background plays a far stronger role while the effect of schooling is minimal; others have…

There is extensive evidence suggesting that school suspension is correlated with poor academic performance. However, many studies examining the association between school suspension and achievement focus on the effects of out-of-school suspension specifically. While in-school suspension is offered as a less harmful alternative consequence to…

Teachers lack effective curriculum-based instruments to assess their students' scientific competence that would provide information for modifying their inquiry instruction. The main purpose of this study was to develop and validate a Curriculum-Based Scientific Competence (CBSC) test to assess students' scientific competence in a 1-semester Grade…

The study aims to analyze student responses to chemistry constructed response items to obtain detailed information on science NAEA (National Assessment of Educational Achievement) in South Korea and to draw suggestions for enhancing curriculum, teaching, and learning. For this purpose, we analyzed 7444 answers that could be generalized as 1.29% of…

Relevance interventions have shown a great potential to foster motivation and achievement (Lazowski & Hulleman, 2016). Yet, further research is warranted to test how such interventions can be successfully implemented in practice. We conducted a cluster-randomized trial in ninth-grade math classrooms to test the effectiveness of a relevance…

The focus of this study is to evaluate the effectiveness of the Student Success Skills group counseling (SSSGC) intervention with grade 9 students identified as at risk to dropout. This study analyzed two years of non-identifiable student data (N = 167) collected by school counselors at one high school in south Florida. An analysis of covariance…
