The following survey study uses a quantitative research design to investigate motivational and affective aspects of students (aged 14-17) in a mathematical workshop on graph theory. Motivational and affective aspects are related to heart rate measurement (using the digital medium of a pulse watch) in mathematical knowledge development processes in…

Computer-based assessments is becoming more and more common in mathematics education, and because the digital media entails other demands than paper-based tests, potential threats against validity must be considered. In this study we investigate how preparatory instructions and digital familiarity, may be of importance for test validity. 77 lower…

Attention is increasingly being paid to integrated science, technology, engineering, and mathematics (STEM) education as a way to increase the workforce for STEM-related careers as well as to promote STEM literacy among citizens. This means that all students, including those who are educationally disadvantaged, are expected to not only acquire…

Science, Technology, Engineering and Mathematics or "STEM" focused pedagogy has been influenced changes in education for decades. Responding to the need for interdisciplinary skilled workforces, the STEM approach has been revised firstly to reflect the incorporation of Arts, (STEAM) and, more recently, to place stronger emphasis on…

Although one of key ideas behind the introduction of STEM (or STEAM) as a unifying concept, is to emphasize the interdisciplinary character of many real world problems, there is a non-trivial educational challenge in exceeding existing subject boundaries and implementing multidisciplinary activities into the classroom. The present case study…

The aim of this mixed research is to analyze the students' perception about the use of the collaborative wall in the educational process of global climate change considering data science. The collaborative wall is a web application that allows the active participation of students and discussion of ideas in the classroom. During the face-to-face…

Molecular genetics, a key concept in biology, is found to be very difficult for students at the senior high school level. A situation largely blamed on teachers' instructional approaches. Since the Relating, Experiencing, Applying, Cooperating and Transferring (REACT) strategy is reported to be an effective pedagogical approach for improving…

The study used experimental research design to randomly selected senior high school students in analysing their attitude and achievement in statistics when contextual teaching is implemented. In addition to structured questionnaires, semi-structured interviews with the students were also conducted to provide rich descriptions about learning…

This work presents the result of the application of a didactic sequence designed to understand the concept of the Cavalieri's Principle, supported by the GeoGebra application in its version for mobile phones -- 3D Calculator. For this study, the Theory of Categories of Intuitive Reasoning, by Efraim Fischbein, was used as a conceptual basis. The…

This study was conducted to analyse the influence of learning styles and teaching strategies on academic performance in mathematics. Surveys were conducted to 277 randomly selected grade 9 students and five purposively sample mathematics teachers. Findings reveal that most of the student-respondents have a combination of dependent, collaborative…

This article explores five educators' conceptions of the characteristics of mathematically gifted students and a social learning environment that supports their development in a school for mathematically gifted adolescents in Finland. We conducted this qualitative study through semi-structured interviews and participant observations in a Finnish…

This study focuses on a comparison of personal meanings that students from Finland (FIN) and Germany (GER) assign to (learning) mathematics. Participants are 256 Finnish and 276 German ninth graders. The survey consists of 18 scales that are based on the theory of personal meaning. The original German version was translated into Finnish. Using…
