An onto-semiotic analysis of the mathematical connections established by one in-service mathematics teachers and university students when solving a problem about launching a projectile using the derivative was carried out. Theoretically, this research was based on the articulation between the Extended Theory of Mathematical Connections and the…

The use of different registers to represent mathematical concepts enhances understanding. For example, rational numbers can assume pictorial, symbolic and natural language representations and this kind of change improves learning. Based on these assumptions, a teaching experiment for the learning of rational numbers by 2nd grade students was…

This action research examined the process of integrating students' out-of-school digital literacy into a second language composition class and the role of social mediation in developing learner agency. It involved EFL students with pre-basic and basic proficiency (pre-A1 to A1-A2 on the CEFR level) in a Saudi Arabian university. Using socially…
