The question of grouping students into homogeneous and heterogeneous groups is not new, but it does not find an unambiguous answer in the literature, especially in mathematics. In this paper, we address the question of whether grouping students into homogeneous and heterogeneous groups in mathematics improves their knowledge. The quasi-experiment…

Advances in embodied learning and the use of gesture has gained greater interest amongst educators and researchers in recent years. The emerging evidence supporting the use of physical enactment rather than just auditory modes of instruction remains unresolved. This paper investigates the pedagogical methods used by a science teacher instructing a…

Dialogic talk affords students opportunities to share ideas and co-construct knowledge while developing various literacy skills such as perspective taking, text comprehension, and argumentative reasoning. In this study, we examine how seventh- and eighth-grade students in four classrooms discuss a controversial topic about changing a National…

Background: Very few studies have properly identified how peer victimization is associated with lower achievement in middle or high school. In this context, this study examined how peer victimization at the beginning of middle school is linked with subsequent student achievement. Specifically, it assessed if the behavioral, affective, and…

Background: There exist shared competencies between computational thinking (CT) and mathematics, and these two domains also mutually benefit from various teaching approaches. However, the linkages between mathematics and computational thinking lack robust empirical support, particularly from student-centered learning perspectives. Our study aimed…

This study explored the relationship between mathematics performance and learning styles among Grade 8 students in the Philippines. The study used a descriptive correlation research design to achieve its objectives, which included determining the profile of Grade 8 students, identifying their learning styles, and examining the relationship between…

The National Assessment of Educational Progress (NAEP) is an integral measure of academic progress over time. It is the largest nationally representative and continuing assessment of what our nation's students know and can do in various subjects such as mathematics, reading, and science. The program also provides valuable insights into students'…

This study examines the factors affecting the mathematics achievement of 8th-grade students in Türkiye using data from the TIMSS in 2011, 2015, and 2019. The data were analysed with multilevel (two-level) modelling. The first level was the student, and the second level was the school. At the student level, such affective characteristics as…

COVID-19 has permeated news since December 2019 and has impacted all areas of life. Despite widespread coverage of COVID-related risks, there is limited understanding of adolescent resilience in Global South contexts (e.g., Africa) and against the backdrop of COVID-19. We, therefore, conducted a qualitative secondary analysis of 79 documents…

This study aims to develop a valid and reliable achievement test to measure the achievement of eighth-grade students in the "Seasons and Climate" unit of the science course. The research was carried out using a survey model. The study group consists of 298 eighth-grade students studying in various cities in Turkey in the 2020-2021…

Teaching and learning mathematics has many challenges, including student engagement, attitudes and beliefs toward mathematics. Students experience stress and anxiety while learning mathematics. Mathematics is perceived as a complex subject. Student self-efficacy and a sense of utility value of mathematics topics can impact student learning and…

We examined the effects of applying the instructional method of constructive controversy in an animal welfare unit, on middle-school students' knowledge and attitudes relating to the treatment and welfare of animals. Accordingly, we developed and implemented a four-stage instructional model centring on constructive controversy in a class of 27…

This study investigated children's knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was…

Although the relationship between reading fluency and high-stakes test achievement is well known, studies were conducted in similar contexts. This correlational study aimed to investigate the relationship between reading error types (insertions, omissions, mispronunciations, and total) and reading fluency (rate, accuracy, and prosody) in narrative…

Targeted school-based programs seem to be a promising approach to help adolescents in need. Nevertheless, successful implementation and evaluation of such programs is challenging. However, there is limited knowledge about (overcoming) the challenges of implementation and experimental evaluation of school-based programs. The goal of the present…
