This paper aims to discuss the use of Brousseau's Theory of Didactical Situations in mathematics (TDS) for eighth-graders to explore the concept of triangle inequality in Euclidean geometry. Data sources included observation notes, video recordings of lessons, and students' written work. Data analysis was done through a deductive content analysis…

A sociocultural perspective considers science textbooks as 'cultural supportive tools' with significant cultural missions. By juxtaposing symbolic, mathematical, and visual-graphical text, textbooks present the intertexts deployed by the scientific community to convey conceptual understandings in a way that no one form can. Intertextuality entails…

Flexibility in transforming algebraic expressions is recognized as fundamental for a rich procedural knowledge. Here, flexibility in-depth is proposed as the ability to apply one strategy to a wide range of unfamiliar expressions. In this study, design experiments with four groups of students were conducted to support students' flexibility…

This is a mix methods follow-up study in which we reconfirm the findings from an earlier study [Vedder-Weiss & Fortus [2011] "Journal of Research in Science Teaching, 48(2)", 199-216]. The findings indicate that adolescents' declining motivation to learn science, which was found in many previous studies [Galton [2009] "Moving to…
