This paper reports on CodeOrama, a visualization tool that displays the entire source code in a two-dimensional representation created to support the representation of a complex code in block-based programming environments, like Scratch, by using a two-dimension table. CodeOrama can be used by the students for the development of their programs as…

A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was…

In this work, we describe an educational approach based on augmented reality (AR) and mobile technology that has been developed with the aim to engage students in a learning procedure regarding the electric forces as well as Coulomb's Law. Initially, we present the AR learning environment and we explain its design principles with respect to the…

Thirty 6-year-olds from two public schools located in a small provincial town in Greece were used as a sample in an explorative study into the mental models young children hold concerning forest destruction and waste. The study also explored how these mental models might be interrelated either within each issue or between issues. The analysis of…

The University of Patras' Library Services designed and offered to primary and secondary schools the pilot educational program "From the Ancient to the Modern Tablets," featuring immersive multimedia learning experiences about the book history. The pilot program consisted of three stages: a playful library tour, followed by an…

This study explores American and Greek primary pupils' visual images of scientists by means of two nonverbal data collection tasks to identify possible convergences and divergences. Specifically, it aims to investigate whether their images of scientists vary according to the data collection instrument used and to gender. To this end, 91…

Children's mental representations about physical concepts and phenomena play a vital role in the learning process. This is confirmed by the data derived from relevant researches which demonstrate that the students formulate incompatible ideas compared with the scientific ones. In this research we investigate the representations of 14-15 years old…

Background: The study investigated a small range of cognitive abilities, related to visual-spatial intelligence, in adolescents. This specific range of cognitive abilities was termed "graphic abilities" and defined as a range of abilities to visualise and think in three dimensions, originating in the domain of visual-spatial…

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…
