This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…

This study concerns a framework for designing Teaching-Learning Sequences that aims to integrate the implementation of scientific practices in the context of daily problems. Said framework consists of three stages (formulation of the design principles, instructional design and design of the learning activities). It is based on four design…

Teaching and learning are time-dependant processes. It can be hypothesised that the content coherence during a teaching sequence is an important factor of learning. In this perspective, it is of great interest to follow the occurrences of a notion and the development of its meanings in the classroom discourse, all along the various sessions of a…

One notable line of inquiry, aspects of which date back to the early 1980s, involves the design and implementation not of long-term curricula, but of topic-oriented sequences for teaching science. One distinguishing characteristic of a teaching-learning sequence (TLS) is its inclusion in a gradual research-based volutionary process aiming at…

This paper reports upon a study addressing teaching and learning about solubility to Turkish first-year secondary school students (age 14-15). The principal aim of the research was to investigate the impact on students' understanding of solubility, of introducing a simple particle model of matter. A teaching intervention to fit within the existing…
