New Learning

Applying new learning methodologies in education, such as visual learning based on virtual reality and three-dimensional (3D) environments, is an important aspect in education, since it offers possibilities that can remarkably improve the current education system. Technological advances, along with the chance to create and represent the varying contents offered by information technologies, make the new learning methodologies the focus of attention in the future. Currently, 3D methodologies are only used in Computer Science to improve physical characteristics (virtual laboratories, virtual worlds, etc.), but they are not used to improve the internal mental processes by which human beings understand and retain abstract concepts. In these cases, the use of visual learning helps to clarify them. In Computer Science, particularly in Software measurement courses, the complexity of the concepts is possibly greater than in other courses because there is a lot of learning material that is based on abstract concepts that students find hard to recognize in the real world. In this paper, we present a visual environment that can be used to learn software measurement concepts like the IFPUG functional size measurement method. To validate the new learning model, an experiment was carried out.

В данной статье анализируются процессы адекватного решения вопросов об организованном и неорганизованном обучении и так называемом наглядном обучении, а также о воспитательном пространстве и о соотношении воспитания и визуализации в образовании, а точнее о процессе представления графической информации визуально и кинестетическим способом с помощью инновационно-информационных технологий. Проведенный нами анализ показал, что умение моделировать в среде трехмерной компьютерной графики позволяет ученику рассмотреть все фигуры при обучении пространственным фигурам в школе. This article analyzes the processes of adequate solution of questions about organized and unorganized learning and the so-called visual learning, as well as about the educational space and the relationship of education and visualization in education, or rather about the process of presenting graphic information visually and kinesthetically using innovative information technologies. Our analysis showed that the ability to model in the environment of three-dimensional computer graphics allows the student to consider all the figures when teaching spatial figures at school.

The cognitive, developing, illustrative potential of three-dimensional computer graphics actualizes the training of future teachers in its technologies. The future teacher of computer science should be able to develop three-dimensional models and animations of the studied objects (phenomena and processes) in computer science, physics, mathematics and other academic disciplines, create copyright electronic educational resources with three-dimensional illustrations, apply augmented reality and 3D printing in professional activities.The article describes the features of teaching three-dimensional computer modeling and visualization of future informatics teachers, identified on the basis of an analysis of the training system for students studying in specialty 1–02 05 02 Physics and Informatics at the Maxim Tank Belarusian State Pedagogical University.The main directions for improving the learning process of three-dimensional computer graphics of future informatics teachers are indicated. Questions on three-dimensional computer modeling and visualization will pass through the content line through the content of six academic disciplines («Computer graphics and multimedia», «Computational methods and computer modeling», «Programming Technologies and Algorithmization Methods», «Information Technologies in Education», «Methods teaching informatics» and «Architecture and software of computer systems»). This will ensure consistency in the introduction and study of concepts, the choice of forms and methods of teaching, the development of teaching and methodical support. For the implementation of interdisciplinarity, it is proposed to carry out practice-oriented interdisciplinary educational projects in the framework of the study of academic disciplines in three subject areas «Computer Science», «Physics» and «Mathematics». The development of a methodical system of interdisciplinary education will ensure the formation of readiness to teach three-dimensional graphics at the stage of general secondary education and to realize its didactic possibilities in organizing educational and research activities of students.

From 2007 and now on, it is a common premise for scholars and educators to use multi-user virtual worlds (VWs) in order to enhance students' technological literacy with contemporary learning strategies. The corollary of interactivity and social formalization of modeling processes in an open source, server-based (standalone) virtual environment is a unique dimension that allows all users (students and instructor) to design a plethora learning activities in conjunction with the most contemporary pedagogical approaches. Accordingly to these provisions, this study focused on the implementation of a collaborative project-based course in computer science by taking advantage of the open source virtual world Open Simulator (Open Sim). The current case study seeks to present preliminary findings from collaborative experiences of an effort that thirty-five (35) postgraduate and undergraduate students participated with the hybrid instructional format in order to investigate the value of this effort for learning introductory programming lessons. This effort tries to articulate initial perceptions of students' assessments based on an inquiry-based collaborative learning (IB[C]L) script that they involved, and secondarily to demonstrate the multisensory-multimodal potential perspectives or educational implications that are being emerged from the exploitation of three-dimensional (3D) technologically-advanced environments.

AbstractHistorical costumes are part of cultural heritage. Unlike architectural monuments, they are very fragile, which exacerbates the problems of their protection and popularisation. A big help in this can be the digitisation of their appearance, preferably using modern techniques of three-dimensional representation (3D). The article presents the results of the search for examples and methodologies of implementing 3D scanning of exhibited historical clothes as well as the attendant problems. From a review of scientific literature it turns out that so far practically no one in the world has made any methodical attempts at scanning historical clothes using structured-light 3D scanners (SLS) and developing an appropriate methodology. The vast majority of methods for creating 3D models of clothes used photogrammetry and 3D modelling software. Therefore, an innovative approach was proposed to the problem of creating 3D models of exhibited historical clothes through their digitalisation by means of a 3D scanner using structural light technology. A proposal for the methodology of this process and concrete examples of its implementation and results are presented. The problems related to the scanning of 3D historical clothes are also described, as well as a proposal how to solve them or minimise their impact. The implementation of the methodology is presented on the example of scanning elements of the Emir of Bukhara's costume (Uzbekistan) from the end of the nineteenth century, consisting of the gown, turban and shoes. Moreover, the way of using 3D models and information technologies to popularise cultural heritage in the space of digital resources is also discussed.

This paper presents a template-based solution to overcome technical barriers non-technical computer end users face when developing functional learning environments in three-dimensional virtual worlds (3DVW). iVirtualWorld, a prototype of a platform-independent 3DVW creation tool that implements the proposed solution, facilitates 3DVW learning environment creation through semantics-based abstract 3DVW representation and template-based 3DVW instantiation. iVirtualWorld provides a wizard to guide the 3DVW creation process, and hide low-level programming and 3D design details through higher-level abstracts supported by pre-defined templates. Preliminary evaluation of the effectiveness of iVirtualWorld showed positive results. The contribution of this study is threefold: 1) It provides a paradigm for investigating and developing 3DVW building tools from end users’ perspective; 2) It develops a prototype of a 3DVW building tool, which gives educators a framework to easily create educational virtual worlds using domain-specific concepts; 3) It conducts empirical research and collected preliminary experimental data for evaluation.

The existing structures of the steel sinking headgear and permanent headframe do not meet the requirements of resource saving (metal consumption and manpower input at installation), and the present methods of the headframe designing do not fully reflect recent possibilities of applying of the advanced information technologies. Technical level of the modern software makes it possible for designers to set up multiple numerical experiments to create a computer simulation that allows solving the problem without field and laboratory experiments, and therefore without special costs. In this regard, a mathematical simulation has been developed and based on it, software to select cross-sections of multi- purpose steel headframe elements and to calculate proper weight of its metal structures depending on the characteristics and hoisting equipment. A headframe drawing is displayed, as the results of the software work, including list of elements, obtained optimal hoisting equipment in accordance with the initial data. The software allows speeding up graphic work and reducing manpower input on calculations and paper work. The software allows developing a three-dimensional image of the structure and its functional blocks, based on the obtained initial parameters, as well as developing control software for units with numerical control (NC) in order to manufacture multi-purpose headframes.

Purpose – This study aims to examine the nature and the potential use of avatar-based focus groups (AFGs) (i.e. focus groups conducted in three-dimensional [3D] virtual worlds [VWs]) as compared to face-to-face and online focus groups (OFGs), motivated by the ability of VWs to stimulate the realism of physical places. Over the past decade, there has been a rapid increase in using 3D VWs as a research tool. Design/methodology/approach – Using a two-phase reflective approach, data were collected first by using traditional face-to-face focus groups, followed by AFGs. In Phase 2, an online, semi-structured survey provided comparison data and experiences in AFGs, two-dimensional OFGs and traditional face-to-face focus groups. Findings – The findings identify the advantages and disadvantages of AFGs for marketing research. There is no evident difference in data quality between the results of AFGs and face-to-face focus groups. AFG compensates for some of the serious limitations associated with OFGs. Practical implications – The paper reflects on three issues, data quality, conduct of AFGs (including the moderator reflection) and participant experience, that together inform one’s understanding of the characteristics, advantages and limitations of AFG. Originality/value – This is the first paper to compare between AFGs, traditional face-to-face focus groups and OFGs. AFG holds many advantages over OFGs and even, sometimes, over face-to-face focus groups, providing a suitable environment for researchers to collect data.

The thermography as a methodology to quantitative data acquisition is not usually addressed in the degrees of university programs. The present manuscript proposes a novel approach for the acquisition of advanced competences in engineering courses associated with the use of thermographic images via free/open-source software solutions. This strategy is established from a research based on the statistical and three-dimensional visualization techniques over thermographic imagery to improve the interpretation and comprehension of the different sources of error affecting the measurements and, thereby, the conclusions and analysis arising from them. The novelty is focused on the detection of non-normalities in thermographic images, which is illustrates in the experimental section. Additionally, the specific workflow for the generation of learning material related with this aim is raised for asynchronous and e-learning programs. These virtual materials can be easily deployed in an institutional learning management system, allowing the students to work with the models by means of free/open-source solutions easily. Subsequently, the present approach will give new tools to improve the application of professional techniques, will improve the students’ critical sense to know how to interpret the uncertainties in thermography using a single thermographic image, therefore they will be better prepared to face future challenges with more critical thinking.
