Virtual and Real Geometry Learning Environments
Over the last years a lot of web-based courses in all disciplines had been developed and different kind of distance and e-learning had been introduced. There was an over assessment of e-learning possibilities like web-based learning. Still a face to face interaction between teacher and student has remained indispensable. The poor student/professor ratio of 200:1 in the lectures of de- scriptive geometry for students of architecture, civil engineering and education in building tech- niques at our university asks for an additional tutoring system. Therefore we introduced in the De- scriptive Geometry course in winter semester 2007/2008 the "Blackboard Learning System CE" through the Virtual Campus Rhineland-Palatinate as an e-tutoring tool. E-learning information and communication tools meet the students in their everyday habits. In this system we take advantage of multimedia technologies for communicating, sparking the interest of the students in geometry and supporting the...
Virtual Environments for Mathematics and Geometry Education
Since ancient times mathematicians and geometricians have used visualisations to describe, discuss, study and teach mathematics. In mathematics education, visualisations are still used whenever possible to support teaching, to inspire students and feed their need to actually see abstract mathematical facts. In our times, virtual reality presents a fascinating, extremely motivating new tool in teachers' hands which allows students to see mathematics in three dimensions. This article gives an overview of various, mainly immersive, virtual environments that have been developed in the previous 10 years to support mathematics and geometry education. The focus lies on one advanced application for geometry education that has been used and evaluated with over 500 students throughout the years. Findings and teaching experiences are described and discussed.
A new focus for teaching and learning with descriptive geometry's tutorials through the web.
The purpose of this paper is to implement a pedagogical proposal for teaching and learning of the descriptive geometry course through tutorials of three-dimensional animations cre-ated with 3D Studio Max software, to be seen in a web site, in an illustrative, detailed, and dynamic manner. A methodology is described to design a master class in a particular subject of descriptive geometry to be seen in an average time of 5 minutes, with constructive and visual process explained step by step. This visual aid can be used as pedagogical support for teachers and students; it can also be used as a bibliographic reference in the curricula that offer this course, and is very useful for e-learning; likewise, serves as a role model for teachers and professionals who want to develop sim-ilar projects in various topics and applications.
DESIGNING THE 3D GUI OF A VIRTUAL REALITY TOOL FOR TEACHING DESCRIPTIVE GEOMETRY
Today, the design of a suitable graphical user interface (GUI) is recognized by designers, researchers and developers as a vital part of the development of software and even of hardware. It must take into consideration both the application context and the interaction tasks to be carried out by the target users. Most current computer users are getting used to a standard set of user interface components and adapting to common interaction techniques for performing their tasks. In spite of this adjustment, it is known that generic interface components like buttons and menus are not always appropriate for use in non-traditional computer environments and in applications with modern interaction techniques, especially Virtual Reality (VR). In VR environments, the user manipulates and interacts with objects, in any orientation, positioned in space. Interaction in 3D space has been explored in several areas and, among them, for teaching Geometry. Some interesting results on learning and user satisfaction have been reported. Descriptive Geometry, although based on a planar (2D) representation, can also benefit from such kind of interface as it concerns 3D space. For this reason, VR tools could improve teaching of Descriptive Geometry in engineering and other courses when used as an enhanced technique for visualization and interaction. This paper presents the design of a new 3D user interface intended to be integrated in the traditional descriptive geometry class setting. The device selection, requirements and specification of interface behavior and components are covered here. The proposed system, still under development, will be a VR tool aiming to improve the spatial visualization abilities of engineering students, promoting comprehension of complex spatial geometric exercises, especially by low visualizers.
Application of Virtual Reality in a Learning Experience
The project is an application that allows users to interact in a virtual environment via a web interface, in which models are in three dimensions to simulate different activities. The application focuses on education with virtual reality technology, enriching the student's perception through the interaction with objects in an artificial world, facilitating their learning. A website was designed for this purpose, on which the application can be executed directly in the web browser with the help of a plugin or downloaded and run as a native application. The user navigates in the virtual environment containing a three-dimensional replica of one of the laboratories of the Polytechnic School N.U.E.. The tests consisted of running the model and laboratory simulations. The results obtained from forms show that the use of virtual reality is valid, accepted and helps understanding the context of the simulations.
Virtual reality technology applied in engineering education

The three-dimensional geometric models used to present architectural and engineering work, show only the final form, which does not allow progress in constructions to be observed. But, the visual simulation of the construction process of a building need models which are able to produce dynamic changes to their geometry. This paper reports how techniques of geometric modelling and virtual reality were used to obtain models that could show their physical evolution over time and which would be able to simulate construction processes visually. Two types of work, concerning the construction of a cavity wall and a bridge, were developed as virtual models for educational purposes. These models make it possible to view the physical evolution of the work, to follow the planned construction sequence, to visualize details of the form of every component of each work and to support the study of the type and method of operation of the equipment necessary in the construction process. These models have been used to distinct advantage as educational aids in first-degree courses in Civil Engineering. The use of virtual reality techniques in the development of educational applications brings new perspectives to the teaching of subjects related to the field of construction.
Virtual Labs and Geometrical Software as a Tool for more Effective Teaching
The International Journal of E-Learning and Educational Technologies in the Digital Media, 2016
Significant development of information and communication technologies and Internet boom brings new possibilities in teaching STEM subjects at all levels of the educational process. In first part we want to present some results of international ICILS study 2013 related to the digital competences of pupils related to the computer aided education, which use virtual reality and computer simulations. The virtual reality is distinguished by unique sorts of interaction, that responds to users' behaviours and actions. It is considered to be a new model of computer-based learning that provides the individual learner with a wider range of scientific vision. In mathematics education it is important to represent and visualize various mathematical concepts, relationships and practices including algorithms. Visualization is usually implemented through different models. It is possible to present these models using virtual and remote laboratories. These models may have the form of real mathematical devices, but may also be implemented in a suitable virtual software environment. Virtual modelling has particular importance in the stages of cognitive processes in STEM education.
Design and use of a multimedia trainer for the subject Descriptive Geometry
Computer Applications in Engineering Education, 2009
Less and less time is being dedicated to Descriptive Geometry in Technical Careers. For that reason, a multimedia application that allows us improve and optimize the teachingÀlearning process in the resolution of typical problems of this subject has been designed. Easy of use, interactiveness or efficiency are characteristics that can be related to this application. In this article, we describe the more important aspects of the developed Multimedia Trainer, as well as the results obtained in an experience with students with the purpose of evaluating its possibilities of use. ß2008 Wiley Periodicals, Inc.

ABSTRACT Due to the difficulty in understanding and learning descriptive geometry, combined with the lack of development of spatial abilities of most freshmen in engineering courses, an innovative tool based on virtual reality techniques was developed to support teaching the theme. The central hypothesis tested was whether the use of modern stereoscopic systems in the teaching-learning process facilitates visualization and understanding of complex spatial situations and therefore supports the development of spatial cognition of students, especially of those with less ability. In general, the three student groups analysed showed improvements in the development of their spatial skills (p<0·001). However, a statistically significant difference could not be detected by the analysis of average gains offered by the different treatments used in the experimental research.
This paper presents the concept of Virtual Laboratories (VL) within the context of Dynamic Geometry Systems (DGS). Despite the fact that a plethora of interactive constructions within DGS has been presented in the literature, the idea of forming virtual laboratories within DGS has not yet been reported. For the design of the proposed laboratories, a modelling methodology was developed. This methodology was based on the design of three models, namely: the learning model based on social and constructivist views regarding knowledge construction, the model of the knowledge domain based on the related specific literature and the student model describing his/her behavior while performing essential tasks for the learning of basic aspects of the previously mentioned knowledge domain. Various capabilities of DGS were also combined so as to assist the construction of the proposed laboratories, e.g. a) presentation of information in Multiple Representation Systems (MRS), b) direct manipulation of the geometrical constructions formed using the tools provided, and c) formation of appropriate buttons for illustrating/hiding the specific constructions viewed as appropriate/inappropriate for the learning of specific aspects of the concepts in focus. As a result of the modelling process, an architecture and a typical interface of the said labs were formed. The previously mentioned methodology and architecture were used for the design and implementation of specific VL for the learning of basic issues of Euclidean Geometry. To clarify the methodology and architecture proposed, a specific example regarding the design and implementation of a specific virtual laboratory for the learning of the mathematical concept of angle is also presented.
