The issue of students' difficulties in processing operations with percentages has been addressed in several international research studies from a qualitative perspective. In this study, we analyze students' difficulties on this topic, focusing on the transition from middle school to high school with a mixed methods research design. We focus on…

Transdisciplinary thinking is crucial for addressing global challenges, yet standardized assessment tools for high school students are lacking. This study addresses this gap by developing and validating a transdisciplinary thinking scale (TTS) tailored for this demographic. Following established methodologies, the TTS was crafted through expert…

There has been a strong narrative in Australia of falling attainment in high school science, with much of the campaign informed by results from international standardised tests such as Programme for International Student Assessment (PISA), which shows a year-on-year decline in scientific literacy of Australian 15-year-old students. These results…

Given the large differences in educational attainment observed across non-Indigenous population groups in Canada, understanding when these differences emerge and what may explain them is an important first step in informing policy discussions on the issue. Using the British Columbia kindergarten to Grade 12 dataset, the Postsecondary Student…

The use of a computer and internet connection allows high school and university students to access more relevant information. However, there is no consensus on the effects of the use of these tools on academic results. This work evaluates the impact of computers and the internet at home on the results of the Saber 11 test, a national exam taken by…

Assessing student mathematical knowledge is an important factor in the mathematics learning process because students obtain important feedback to improve their knowledge and learning. Despite the importance of student assessment, several researchers have shown that student grades comprise noncognitive and metacognitive factors and teachers'…

In this study, the evaluation of mathematical proficiency (MP) in one NSW Year 12 standardised exam paper was investigated. By considering the multi-strand model of MP, a literature-based criteria for scoring the assessment of MP in individual exam questions was first developed. The criteria were then applied to quantitatively evaluate the 2023…

The study investigated the effects of a combination of Peer Discussion and Isomorphic Problems (PD-IPs) on high school students' graph understanding and conceptual learning. The study was conducted on kinematics and Newton's Laws of Motion with 67 high school students from two groups. The experimental group (EG) consisted of 34 students, while the…

We examined developmental trajectories of attention-deficit/hyperactivity disorder (ADHD) symptoms, standardized achievement, and school performance for adolescents with and without ADHD who did and did not enroll in postsecondary education (PSE; N = 749; 79% boys; 63% White, 17% non-Hispanic Black, 10% Hispanic, and 10% other ethnicities). In a…

This study set out to examine the effectiveness of Robotics and Weblog models in improving English as a foreign language (EFL) proficiency of terminal middle and secondary school graders. Another purpose is to suggest pedagogies required to integrate Robotics and Weblog models in the EFL curriculum and instruction. We collected data using the…

National and international large-scale assessments of mathematics show that, in most nations, males achieve better results than females and Italy is one of the countries with a greater gap. Many research studies in mathematics education have analysed this issue, using both quantitative and qualitative methods to understand the sources and…

Albeit college success predictors such as hs-GPA, SAT I, and SAT II have been widely addressed in the literature, most of the studies have covered total scores and cognitive factors while barely investigating the potential interaction of demographic factors (e.g., STEM versus Non-STEM) and specific academic domains that might drive academic…

This paper focuses on the perspectives of minority/racialized students in urban high schools. It is based on findings of interviews with 85 students in six secondary schools in Toronto and Vancouver, Canada, and in Melbourne, Australia, during 2016-2019. While there has been increasing attention to closing the racial achievement gap and some…

This article presents a didactic situation focused on geometric reasoning using 3D GeoGebra, using the concepts Theory of Didactical Situations (TDS). The objective of this work is to bring a didactic proposal for the teaching of Spatial Geometry, working with the students' geometric perception, oriented and elaborated based on the dialectic of…

This study describes the characteristics of the test and its items used in the national-standardized school examination by applying classical test theory and focusing on the item difficulty, item discrimination, test reliability, and distractor analysis. We analyzed response data of 191 12th graders from one of public senior high schools in…
