Constructionism can be a powerful framework for teaching complex content to novices. At the core of constructionism is the suggestion that by enabling learners to build creative artifacts that require complex content to function, those learners will have opportunities to learn this content in contextualized, personally-meaningful ways. In this paper, we investigate the relevance of a set of app...

This paper focuses on the production of authoring tools that teachers may use to prototype interactive geographical web applications. We present some computational models and a toolset that we designed to address some needs of teachers trying to make use of particular localized documents called “travel stories”. Our research challenge is to enable teachers to design interaction scenarios for su...

This paper analyses the knowledge and software engineering aspects of educational applications that provide affective bi-modal human-computer interaction. For this purpose, a system that provides affective interaction based on evidence from two different modes has been developed. More specifically, the system’s inferences about students’ emotions are based on user input evidence from the keyboa...

In this chapter we present a network architecture and two field application examples involving the deployment of embedded systems for distributed applications in the educational environment. The main contribution intended for this chapter is the proposed network architecture, with emphasis in the specific distributed implementation of networked embedded systems. The contribution also includes t...

A software for the thermal and hydraulic design of shell and tube heat exchangers with flowinduced vibration checks has been developed in a Windows-based Delphi programming environment. Its user-friendly input format and excellent colour graphics features make it an excellent tool for the teaching, learning and preliminary design of shell and tube heat exchangers. Design methodology is based on...

Educational Adaptive Hypermedia Applications (EAHA) provide personalized views on the learning content to individual learners. They also offer adaptive sequencing (navigation) over the learning content based on rules that stem from the user model requirements and the instructional strategies. EAHA are gaining the focus of the research community as a means of alleviating a number of user problem...

This paper presents a UML profile for web–based educational applications. The definition of the profile is provided by applying a certain formalism which is based on the metamodeling architecture of the UML language. An example is given throughout the paper for the illustration of an instantiated model based on the profile.

In online educational systems we can easily collect and analyze extensive data about student learning. Current practice, however, focuses only on some aspects of these data, particularly on correctness of students answers. When a student answers incorrectly, the submitted wrong answer can give us valuable information. We provide an overview of possible applications of wrong answers and analyze ...

Recently, researchers from multiple disciplines have been showing their common interest in automatic question generation for educational purposes. In this paper, we review the state of the art of approaches to developing educational applications of question generation. We conclude that although a great variety of techniques on automatic question generation exists, just a small amount of educati...

For distance education utilizing shared Virtual or Augmented Reality (VR/AR) applications, reliable network distribution of educational content is of prime importance. In this paper we summarize the development of software components enabling stable and reliable distribution of an existing educational AR application for geometry education. Our efforts focus on three main areas: (1) For long dis...
