The design of algorithms is one of the hardest topics of high school computer science. This is mainly due to the universality of algorithms as solution methods that guarantee the calculation of a correct solution for all potentially infinitely many instances of an algorithmic problem. The goal of this paper is to present a comprehensible and…

This study investigates the characteristics of Japanese primary school mathematics lessons that adopt a problem-solving approach. We argue that these characteristics are reflected in three key aspects: collective teaching and learning, the lesson as a "drama" (i.e., its structured flow), and the focus on mathematical knowledge. In this…

This action research aims to develop the ability to solve mathematical problems, particularly in polygons, through open-approach learning management for sixth-grade students, with the goal of achieving an average score exceeding 70% of the total possible score. The target group consisted of eight students in the second semester of the academic…

The purpose of this qualitative study was to examine the use of ChatGPT as a lesson-planning assistant with preservice teachers (PSTs) of secondary mathematics. PSTs asked ChatGPT to solve a mathematics problem and to assist with lesson planning in a microteaching context in a methods course. The PSTs first developed parts of their microteaching…

The aim of this study is to develop a descriptive framework for teacher educators to assist teachers to plan and realize modelling implementations in their classrooms and for researchers to describe and analyse how modelling is implemented. The planning process and implementations of 12 middle and high school mathematics teachers who conducted…

In the face of the global sustainability crisis, schools and teachers are called on to transform education and implement educational innovations to strengthen sustainability education. One of these innovations is 'open schooling': educational practices that involve students in identifying, exploring, and tackling real-world sustainability problems…

This study aimed to design, implement, and evaluate the feasibility of an activity titled "Space Adventure for Little Explorers", integrating the engineering and entrepreneurship design model within the STEM education framework into preschool education. The activity was structured in four stages: (1) Discovery with the Family, (2)…

Academic literacy has evolved significantly over the past two decades, expanding beyond basic reading and writing skills to include a broad range of competencies essential for successful modern education. These competencies - skilled communication, critical thinking, collaboration, and digital literacy - are crucial for preparing students to…

The purpose of this article is to describe the learnings of primary school teachers in rural Guatemala as a result of an action research experience. This experience took place in the context of the "Basic Education Quality and Transitions" activity, or BEQT, funded by the United States Agency for International Development (USAID) and…
