The cognitive reflection test (CRT) assesses an individual's capacity to restrain impulsive and intuitive responses and to engage in critical reflection on mathematical problems. The literature indicates that several factors influence students' performance on CRT, including gender, age, and prior knowledge of mathematics. In this study, our…

This study was conducted while 9th grade students learn to solve inequalities and seeks to understand their approach to solving problems with a real-life context. Specifically, the aim is to understand: (1) What are the main characteristics of the students' approaches to the proposed problems? (2) What is the impact of the real context on the…

Flipped learning is a constructivist methodology that uses various active learning strategies, drawing on the potential of digital technologies whenever possible. Several research studies have shown the many benefits that flipped learning can bring to students' learning process and their affective sphere, but studies in the specific area of…

Historically, college students who require remediation in mathematics have been placed into developmental mathematics courses. Accurate placement is important for student success; inaccurate placement in a low-level course could lengthen a students' time to degree completion. Placement policies have tended to focus on a high-stakes placement test,…

In our investigation of university students' knowledge about real numbers in relation to computer algebra systems (CAS) and how it could be developed in view of their future activity as teachers, we used a computer algorithm as a case to explore the relationship between CAS and the knowledge of real numbers as decimal representations. Our work was…

The article analyses teachers' learning on the use of multiple representations (MRs) in the teaching of Ohm's law, examining them in a lesson study, structured in 18 meetings of 2.5 hours each, that addressed this physics curricular topic for the 3rd grade of high school. The qualitative research involved four teachers who teach physics in…

The current study examined self-organized learning environments (SOLEs) pedagogy as a conduit to learners' metacognitive skills and conceptual understanding in physical sciences and science, technology, engineering, and mathematics (STEM) as a whole in Capricorn District of Limpopo Province of South Africa. The aim was based on ongoing debates…

This work intends to disseminate a didactic experience in mathematics, in times of pandemic, in an emergency remote teaching situation, at the Portuguese School of Cape Verde, using the Desmos digital platform. The topic addressed was the study of the volume of geometric solids. The main objective was to contribute to the learning of mathematical…

This paper focuses on the difficulties encountered by Italian students in performing geometry tasks. A quantitative analysis, aimed at understanding the extent of the phenomenon, is carried out using the results of district competitions from the year 2018 to 2020, comparing the scores obtained in geometry questions with those in other areas of…

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…

In a modern yet demanding society, scientific literacy (SL) is an essential skill that enables the individual to explain, understand and discuss issues related to science, health, and the environment. The purpose of this research study is to validate the Scientific Literacy Assessment (SLA) tool in the Greek language and investigate the level of…

The study covers the development and testing of the alternative mechanics survey (AMS), a modified force concept inventory (FCI), which used automatically marked free-response questions. Data were collected over a period of three academic years from 611 participants who were taking physics classes at high school and university level. A total of…

Teachers' knowledge plays a central role in technology integration. In this study we analyze situations, where there is some divergence between the mathematical results and the information offered by the graphing calculator (lack of mathematical fidelity), putting the focus in the teachers and in their approaches. The goal of this study is to…

Some research works have showed that Ghanaian teachers, teaching chemistry in the senior high school, have conceptual difficulties in organic chemistry. This research explored the factors contributing to teacher's conceptual difficulties on teaching organic chemistry to high school students. Through explanatory sequential mixed methods design…

A questionnaire was recently developed for the use with the Spanish-speaking, and evidence have been provided about the construct internal validity by means of structural equation modelling. In this paper, two research questions were considered: (i) What new evidence does application of the Rasch model provide regarding the validity of this…
