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…

The aim of this research was to assess students' ability to explain scientific phenomena by means of a POE pedagogical tool. To achieve this aim, we conducted home experiments in a digital environment. In this qualitative and transversal ex-post-facto research, 775 pupils (aged 13-18 years) enrolled in compulsory secondary education from the…

Physiology is an integrative science that requires an understanding of the organism as a whole to acquire a deep comprehension of its functions and avoid misconceptions that may impair further learning. Thus it is necessary to develop resources that promote the integrative vision that Physiology requires. Chronobiology is a challenging discipline…

Considering students' increasing lack of interest and motivation for science subjects, it becomes almost imperative to introduce different methodology approaches in classrooms. Besides, decontextualized science teaching, where hands on activities are not sufficiently taken into account, can make the students attitude toward science-learning even…

National governments are concerned about the disconnection of young people from science, which hampers the development of a scientifically literate society promoting sustainable development, wellbeing, equity, and a green economy. Introduced in 2015 alongside Agenda 2030, the "open schooling" approach aims at enhancing students' science…

Modelling-based teaching activities have been designed and analysed from distinct theoretical perspectives. In this paper, we use one of them--the model of modelling diagram (MMD)--as an analytical tool in a regular classroom context. This paper examines the challenges that arise when the MMD is used as an analytical tool to characterise the…

We hereby present the main conclusions and perspectives obtained by the Group of Teaching Innovation in Electronics (Grupo de Innovación Docente en Electrónica, GIDEN) of the University of Valladolid (UVa) with regard to its main areas of work. This group comprises teachers of the "Specialty in Industrial Electronics" degree, and the…

Two commercial self-heating food products have been used to apply chemical concepts such as stoichiometry, enthalpies of reactions and solutions, and heat transfer in a classroom activity. These products are the self-heating beverages sold in Europe and the Meals, Ready to Eat or MREs used primarily by the military in the United States. The main…

During the last few years, the number of university students choosing to follow engineering degrees has decreased dramatically in Spain. For that reason, several university departments, in collaboration with some high schools, have developed a range of activities in order to promote a higher enrollment rate, to improve the level of mathematics and…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
