[more] Since most edutainment applications are designed to support learning in a more enjoyable way taking advance of multimedia, our approach in this project follow a different route. We propose PlayLogo3D which is a LOGO like environment especially designed to be a videogame. Its educational effectiveness is expected to be shown after Elementary school students get involved in formal programming lessons using LOGO or other languages. We concentrate on initial spatial and programming abilities and emphasize that Elementary School students need an introductory level for programming based on their Intuitive knowledge before getting involved with algorithmic concepts. This paper outlines an approach for: A) Use a subset of LOGO language in a 3D environment, B) Design a serious games application for pre-programming education and C) Do all of the above without sticking at the typical educational criteria of ‘right and wrong’.

[more] Παρατίθενται μια σειρά από προβληματισμοί σχετικά με το Γνωστικό Φόρτο (Cognitive Load) κατά την μάθηση της σχεδίασης με βάση τον υπολογιστή (Computer Aided Design-CAD) σε προπτυχιακό επίπεδο. Με δεδομένο ότι οι φοιτητές της Τριτοβάθμιας Εκπαίδευσης παρουσιάζουν αρχικά σημαντική ανομοιομορφία ως προς τις γνώσεις και τις ικανότητες σχεδίασης με CAD, παρουσιάζονται συγκεκριμένες διδακτικές παρεμβάσεις που μπορούν να βοηθήσουν στη διαχείριση του Γνωστικού Φόρτου κατά τη διάρκεια των μαθημάτων και να διατηρήσουν υψηλό το κίνητρο συμμετοχής σε εργαστηριακής φύσεως σχεδιαστικά πονήματα. Σκοπός είναι η γεφύρωση της διαδικασίας σχεδίασης 3Δ μοντέλων και φωτορεαλιστικών σκηνών με τη δημιουργική διάθεση και την ουσία της απόδοσης νέων ιδεών. Οι κοινωνικές αλληλεπιδράσεις και ο έντονα συμμετοχικός χαρακτήρας της εκπαίδευσης σε CAD είναι παράγοντες που οφείλει να διαχειρίζεται ο ακαδημαϊκός δάσκαλος για να οδηγήσει τους φοιτητές στην ανακάλυψη των πιο ενεργητικών στοιχείων της παρουσίας τους στο εργαστήριο.

[more] In this paper the attitudes, expectations and aspirations of students of Professional Schools (EPAS-OAED, formerly TEE) on the use of Virtual Reality applications are extracted to estimate the degree of familiarity (in matter of interaction) with those applications for future educational use. The results were formed using a questionnaire on a small sample of students under laboratory conditions. The analysis of the results highlights some points regarding the benefits that may arise from the use of Virtual Reality applications in educational processes. The responses clearly show the high expectation of using educational software that is technical sound and human-centric. At the same time students show critical thinking about technical and morphological characteristics of Virtual Reality applications.

Designers from various academic disciplines (architects, engineers, graphics designers, etc.) who are more or less familiar with CAD technology seek more creative ways of expression. Since these technologies are in the midst of a rather rapid evolution, tailoring instruction to meet these potential challenges calls for an ongoing modernization as well as a constant adaptation of our teaching methods in order to satisfy the fluctuating needs, not only of the business world, but also of the contemporary teaching practices of adult education. In this paper, an attempt is made to provide an overview of various teaching practices geared toward the creation of a sound learning environment within the CAD laboratory while managing existing concept maps. The goal here is to help reinforce students’ metacognitive abilities since they have been proven paramount in their learning journey. One of the most promising teaching practices illustrated herein is the use of videotutorials as well as the use of video-recordings from student’s screens in the monitoring and improvement of metacognition in individual students.

In this paper we discover how the functional requirements of the VLEs affect and are being affected by the educational, ethnographic and social spaces. It is supported that educational effectiveness of VLE is not proportional only to the quality of learning material, but also to the general educational context of the VLE regarding social characteristics that should be in line with the normal school life. In order to eliminate certain negative issues related to empty and boring VLEs we study the mapping of educational, mental and social spaces into modern virtual environment’s philosophy of use.

[more] The communicative nature of Art is adapted to each society based on the renewal of used media and methods. Today the Plastic Arts have adopted the Information and Communications Technologies (ICT) and a global environment of remarkable extraversion has been created. This environment is reinforced by computer networks, digital collections and virtual art communities over the Internet. Today, ICT constitute a creative environment, a platform for Art-education and a field of wide social attendance in new cognitive and recreational topics. Reversely, the visual nature of multimedia applications is also recognized. Thus, we are led to the acceptance of the term ‘aesthetic computing’ (Fishwick, 2008). The way we interact with the figurative content of software applications is adapted to the characteristics of new media while it follows the theoretical speculations of modern art communities. We lead to the conclusion that the relation of computer with Art is not forcing, nor parasitic. It is a relation of living together with reciprocal utility.

[more] For the complete understanding of concepts of Operating Systems courses, students need practical experience with related algorithms. In order to avoid the high learning effort of writing concurrent programs for experimentation, the development of ready to use programs simulating the algorithms of the kernel is an effective alternative. In this paper, a learning tool has been successfully developed to demonstrate CPU scheduling algorithms and principles through graphical representation of the processes and the CPU workflow. By this approach students can conceptualize the life-cycle of processes and at the same time make modifications of OS algorithms, factors and variables with limited complexity.

[more] Lately, Virtual Reality has offered new presentation methods for exhibitions in museums and galleries. Although the school use of virtual museums can offer a lot to Art educators, the inadmissible cost for creating such an application and the time consuming management of the content, prevent this technology from everyday school life. Our approach aims to offer to Art educators of Primary and Middle school a software platform to create and publish their own virtual museums on the Internet. Before presenting our approach, a review of the international presence of sample of virtual museums in the Internet is considered necessary. Also an attempt to categorize them according to their potential, structure, and contents has to be made. The architectural design, collections creation and content management of our Virtual Reality Learning Environments (VRLE) prototype will be briefly presented.

[more] Virtual Reality (VR) technology offers new options for the study, assessment and rehabilitation of cognitive/functional processes. The capacity of VR to create dynamic three-dimensional environment in which users’ behavioral responses can be recorded, offers assessment and rehabilitation options that are not available using traditional methods. Bearing in mind that the activities of students in school laboratories determine learning goals and methods, the aim of the study is the basic actions which comprise user behavior within the virtual environment. Within the scenario, students are assessed for using the interface in achieving user objectives during visits in selected virtual environments while behavior of student's Avatars are collected in video files. Video analysis of high priority characteristics leads to useful conclusions with regard to student's virtual world behavior and gender differences as well.

[more] The advantage of information technology in “traditional” curriculum areas has created a motive for the introduction of Virtual Reality into the curriculum of Medical Education. We focus on adaptive instruction and learning models, in order to accommodate learners’ individual needs and offer medical-educators an instructional authoring tool. The learning tool is based on a database containing medical slides, video, etc. The software produces an interface easy in use for educators and learners and has a lot of features to make interactive presentations. These can be searching and retrieving via keywords, zooming of slides, an outliner to help the organization of the presentation and the data entry of a usual database. The output of the system consists of multimedia interactive autonomous presentations. The educational activities are also supported by virtual environments, questionnaires and why not educational games.
