The study advances the instrumental approach to mathematics education (Drijvers et al., 2013; Trouche, 2003), aiming to elucidate the interplay between students' reasoning competency, conceptual knowledge and tool utilisation in dynamic digital geometry and algebra environments. The dynamic properties of these environments pose a nuanced…

GeoGebra, a dynamic mathematics software, was used to study high school students' perceptions and achievements in learning trigonometric ratios. The study addresses a critical gap in the literature concerning the use of GeoGebra for understanding trigonometric concepts, particularly in fostering conceptual clarity and problem-solving skills.…

The objectives of this research were to: 1) develop online lessons with the Google Classroom application on computer system operation for secondary 2 (Grade 8) students; 2) study pre-test and post-test academic achievement; and 3) study the students' satisfaction with the online lessons with the Google Classroom application on computer system…

Classrooms are operating differently during the COVID-19 pandemic, especially in lab-based courses. Virtual classrooms utilizing Zoom, Google Meet, or other conferencing software can create challenges for hands-on, lab-based classes. These virtual methods also pose problems for pre-service teacher education students attempting to gain much needed…

This case study investigates prospective middle school mathematics teachers' use of the Angle tool in GeoGebra, focusing on reflex angles in a geometric construction task. They constructed a parallelogram with individual heights for any two consecutive sides. We analyzed their screencasts to identify the ways in which they used reflex angles in…

This study examines modelling with machine learning. In the context of a yearlong data science course, the study explores how upper secondary students apply machine learning with Jupyter Notebooks and document the modelling process as a computational essay incorporating the different steps of the CRISP-DM cycle. The students' work is based on a…

In the era of Industry 5.0, education is evolving with automation and immersive technologies like Augmented Reality (AR). This study explores the need for an AR-based e-module in Senior High School biology by assessing students' understanding, interest, confidence, and perceived usefulness of AR in learning. Using a descriptive quantitative…

The purpose of this study was to investigate the possible effects of conducting regular collaborative activities via Google Docs on English academic writing skills. Utilising a mixed methods design, this study was conducted with 24 Vietnamese high school students who participated in a fully online English as a foreign language (EFL) course in…

The present study investigated the type of influence teachers' technological knowledge, technological pedagogical knowledge, anxiety, age, and years of experience have on their time spent on the MS Teams platform. 171 high-school EFL teachers from the public sector in the city of El Jadida, Morocco, were given a questionnaire adapted from Heinssen…

Purpose: The purpose of this paper is to investigate the impact of personality traits on the perceived usability evaluation of e-learning platforms. In specific, perceived usability levels of the educational platforms and tools used in primary and secondary education in Greece are demonstrated. The impact which personality traits and other…

This paper introduces a system that supports student-centered online one-to-one tutoring and evaluates the practical value of the system by running an experiment with 64 experienced mathematics teachers and 810 students in Grade 7. The experiment lasted for 50 days. A comprehensive evaluation was performed using students' academic performance…

The COVID-19 pandemic has caused an increase in the use of e-learning software. From the perspective of the decision-makers (school/university administration), it is crucial to understand what characteristics of the software are perceived by the users (teachers) as necessary for a task (e-learning). A popular method of determining these…

The home confinement that was imposed to reduce and control the spread of COVID-19 pandemic led educational systems to implement changes in many school activities. Teachers moved to remote teaching and relied on digital apps to present and discuss learning activities with their students. Likewise, they looked for new routes and means to follow up…

Technology needs to be integrated with every learning process. Moreover, the COVID-19 pandemic situation does not allow face-to-face learning in class. Therefore, online education has become the primary choice. However, online learning itself comes with challenges from the perspective of the teachers and their students. This study aims to analyze…

This study investigates the quality of tasks containing the use of dynamic geometry software (DGS) in the middle (5th-8th grade) and secondary school (9th-12th grade) mathematics textbooks in terms of mathematical and technological aspects. The DGS-related tasks in twenty-seven Turkish mathematics textbooks, approved by the Ministry of National…
