The 2018 International Computer and Information Literacy Study (ICILS) provides a comprehensive dataset with contextual information on German school environments. The data comes from responses by eighth-grade teachers and principals to a questionnaire about Information and Communication Technology (ICT) for teaching. We performed an exploratory…

Homework is a self-regulated activity that constitutes a large proportion of learning time. In mathematics, how long is the optimal homework time for achievement development and how to improve homework time efficiency have long been questions. The study examined how mathematics homework time was related to mathematics achievement among Chinese…

Effective classroom management skills are critical in supporting students' academic, social, and behavior development in schools. However, teachers often report support with classroom management as their greatest need. Given this concern, effective and efficient strategies are needed for teachers and school staff dealing with class-wide behavioral…

This study focused on the relationships between teacher characteristics and students' mathematics achievement in EU countries, including Hungary, Italy, Lithuania, Malta, Slovenia, Sweden, and Turkey, which are the only EU countries participated in TIMSS 2015 at the eighth-grade level. The data consisted of the sample of 31,969 eighth-grade…

This paper is a lesson study of the instruction of China's Natural Resources (the third unit of eighth-grade geography), and its objective is to examine the efficacy of inquiry-based learning in geography education. In the experimental lesson, we reorganized the teaching content by integrating the learning materials from the four sections of…

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…
