In this cross-national study, we explore the different ways of reasoning-and-proving (RP) presented in three 8th grade textbooks, one from each country: Turkey, Norway, and Slovakia. While the analysis revealed that all three textbooks contain similar numbers of problems involving some form of RP, differences exist in terms of the dominating ways…

This study aimed to design and validate the Teacher-Reported Reading Engagement Survey (TRRES) to complement self-reported measures and comprehensively assess reading engagement among adolescents. Drawing insights from literature and expert feedback, a new 10-item Likert scale instrument was created, capturing three facets of reading engagement:…

Racially and ethnically diverse populations from minoritized backgrounds are often exposed to research methodologies that amplify structural racism and negate their sociocultural reality. Although cross-cultural validation of measures is considered a requisite step to multigroup comparisons, researchers apply measures validated and standardized in…

In this paper, the White listening subject takes the form of a standardized high-stakes reading test, the State of Texas Assessment of Academic Readiness (STAAR). Although the test does not actually listen, it 'hears' and evaluates children's responses to its questions. I present the results of the 2017 Grade 8 reading exams, from the March, May,…

The aim of this study is to develop a theoretically sound, valid, and reliable scale to examine seventh and eighth grade students' attitudes towards so-called skill-based mathematics questions (SBMQ). The sample of the study was 820 seventh and eighth grade students at three different middle schools in Etimesgut District of Ankara Province. A…

One of the crucial fundamental mathematical skills for students is mathematical communication. This skill pertains to students' ability to convey the ideas and information they have acquired effectively. However, many students still have suboptimal mastery of this skill. Therefore, this study aims to develop worksheets based on realistic…

The aim of this study is to develop a valid and reliable astronomy attitude scale for secondary school students. The method of this research is a scale development study. The study group of the research consists of 300 students studying in 3 different secondary schools in Turkey in the first semester of the 2022-2023 academic year. A 32-item…

Background: Authentic situations are considered a source of learning due to their real world relevance. This can encourage learners to acquire new knowledge. Increasing digitisation and associated resources, such as professional development opportunities for teachers, technology tools, or digital equipment for schools enable the development and…

Mathematical justifications offer an approach to which students deepen and extend their mathematical thinking. This process has the potential to enhance students' conceptual understanding. Mathematical practices and process standards ask students to use critical thinking skills to justify their reasoning, but this is usually seen as proofs in high…

We present a case study of proving by three 12-13-year-old students with different levels of mathematical giftedness. After analysing students' proofs, we conclude that: there was a relation on the consistency and the students' levels of mathematically giftedness, being the least consistent the student not mathematically gifted and the most…

Climate change in coastal areas is a complex problem that involves value systems and requires various scientific disciplines. Integration of Science, Technology, Engineering and Mathematics (STEM) approach is needed in learning so that it can train students to think holistically, structured and systematically. This research was carried out with…

This study focused on improving students' learning mathematical of proofs and proving by using combinations of proof strategies that span different levels of understanding of proof structure; we refer to these as 'level-spanning proof-production strategies'. We analysed the level-specific proof-production strategies evident in the lessons and…

In this study, the aim was to develop a measurement tool that would provide a valid and reliable assessment of secondary school students' mathematical resilience skills. The research was conducted with a sample of 229 students. To ensure the content and face validity of the scale, expert opinions were initially sought, and the scale was revised…

Understanding motivational beliefs such as expectancy and value that shape students' persistence and decision to pursue a STEM career, obtaining valid and reliable measures for these dimensions, and developing strategies using this data are critically important to ensure students' persistence in the STEM pipeline. Therefore, this study aims to…

The research aims to develop a valid and reliable scale to determine secondary school students' perceptions of role modeling. The survey design model, which is a quantitative research method, was used in the research. The study's sample comprised 500 students enrolled in three secondary schools in Turkey during the 2018 spring semester. Data for…
