The focus of the present study is the learning processes of concepts related to hydrogen bonds, which were developed using a didactic sequence (DS). Based on the perspective of Imre Lakatos, it was observed whether the explanatory models created by upper-secondary students form progressive transition sequences, which are similar to what Lakatos,…

Students' understanding of the electronic structure of the atom has been investigated by many authors. This study outlines students' conceptual and representational understanding of quantum concepts explored in lower and upper level chemistry courses, in three different chemistry majors, identifying learning obstacles and monitoring student…

Learning the physiology of the cardiovascular system can be difficult for students, but the use of active teaching methodologies can help and enhance learning. To facilitate the understanding of how the cardiovascular system works, we built a functional model for Veterinary Medicine students attending a cardiovascular physiology lecture and…

Use of mobile devices and widespread adoption of wireless networks have enabled the emergence of Ubiquitous Computing. Application of this technology to improving education strategies gave rise to Ubiquitous e-Learning, also known as Ubiquitous Learning. There are several approaches to organizing ubiquitous learning environments, but most of them…

Research in the learning sciences is often motivated by the goal of shaping a better future through design. Architects and urban planners share this goal, and the history of their more ambitious designs provides clear examples of how attempts to build the future can turn out. After discussing similarities and differences between design in the…

This paper presents and discusses students' learning process of chemical equilibrium from a modelling-based approach developed from the use of the "Model of Modelling" diagram. The investigation was conducted in a regular classroom (students 14-15 years old) and aimed at discussing how modelling-based teaching can contribute to students…

Learning cycles were developed in Brazil as an innovative project in order to address the needs and characteristics of the country's growing heterogeneous urban population. This new school model aims at reducing dropout rates and student failure as well as providing a non-interrupted school experience for diverse learners. In this article, the…

These proceedings contain the papers of the IADIS International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2013), October 22-24, 2013, which has been organized by the International Association for Development of the Information Society (IADIS), co-organized by The University of North Texas (UNT), sponsored by the…

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…
