This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

Climate change in coastal areas is a complex problem that involves value systems and requires various scientific disciplines. Integration of Science, Technology, Engineering and Mathematics (STEM) approach is needed in learning so that it can train students to think holistically, structured and systematically. This research was carried out with…

This paper introduces a model built upon the Method of Varying Inquiry, offering a didactical approach to problem posing and solving activities that stimulates inquiry-based learning in mathematics classrooms. The model combines the inquiry-based framework with the variation theory and with specific didactical and theoretical elements (the…

Mathematical and computational thinking (CT) are closely interrelated, yet CT integration into mathematics instruction remains limited. This study aims to analyze the effectiveness of the teaching process for straight-line equations in enhancing students' CT skills and to propose improvements based on the findings. A qualitative case study…

Students need to be actively engaged to learn--intellectually curious, physically active, and emotionally involved in collaborative work that builds their capacity for empathy. What can teachers do to instill these elements in the classroom? "Active Learning: 40 Teaching Methods to Engage Students in Every Class and Every Subject" is the…

This study examines the development of learning designs based on Realistic Mathematics Education (RME) on the probability topic at the eighth-grade junior high school level. Probability abounds in everyday life, and the RME approach is believed to develop students' mathematical communication skills. This learning design development used the Plomp…

In this paper we introduce a theoretical framework concerned with fostering functional thinking in Grade 8 students by utilizing digital technologies. This framework is meant to be used to guide the systematic variation of tasks for implementation in the classroom while using digital technologies. Examples of problems and tasks illustrate this…

In this paper, we explore how students' algebraic noticing's and explanations changed across a two-year period with the introduction of designed instructional material. The data in this report is drawn from n=53 Year 7-8 students' responses to a free-response assessment task across two different years. Analysis focused on how students noticed and…

This study aimed at designing instructional material named Biotechnology Instruction Module (BIM) which is enriched with active learning methods to enhance the 8th grade students' learning of the topic. The development of the teaching materials proceeded within the stages of the ADDIE instructional design model. The final form of the instructional…

This article describes the design and implementation of a project from a translanguaging pedagogical stance. The research presented seeks to understand how translanguaging as a multimodal practice shapes the experiences of students in a traditional English Language Arts 8th-grade classroom and how students leveraged their multimodal semiotic…

Many students do not experience usefulness in mathematics. To address this problem, we offered them a mathematical tool, Sankey diagrams, which is a flow chart appearing in news media to visualize social, industrial or environmental processes. We carried out an Educational Design Research (EDR) to develop and evaluate lesson materials about…

Given the concern of presenting physical education environments that promote equity, it is appropriate to study innovations that can achieve that goal. In this study, that innovation took the form of student-designed games (SDG). SDG is the process in which students create, practice, and refine their own games and in which the teacher acts more as…

This study focuses on how the combined use of graphic calculators with connectivity software promotes the social construction of mathematical knowledge. Particular emphasis is placed on the aspects related to design, development, implementation, and evaluation of didactic activities that integrate these technologies. We use Didactical Engineering…

When eighth-grade students tire of writing, their history teacher must get creative to keep their attention for the next project. By applying a multimodal design to an old project, the teacher creates a new one that appeals to various learners and creative minds. The result is not only historical learning but also an opportunity to see how…

Project-Based Learning (PBL) serves as an instructional approach to classroom teaching and learning that is designed to engage students in the investigation of real-world problems to create meaningful and relevant educational experiences. The causal-comparative study compared 7th and 8th students who had utilized the PBL with a comparison group in…
