Its greatest advantage over classical technical drawing and 2D drawing software lies in the fact students are able to observe the object they are designing from all the viewpoints of a virtual three-dimensional space. Since thinking and visualization in the process of object design also appear in three dimensions, the mental manipulation and guesswork required from students in order to add another dimension to an object pictured on a level plane are no longer necessary. Additionally, 3D modeling has a range of contributions to the cognitive development of children, which was also the subject of this research. The central question raised was whether students are able to improve their spatial ability by using modeling tools. The research included 196 students aged between 11– 15 years, of which 95 were placed in the experimental group and 101 in the control group. Spatial ability was measured using pre-test and post-test. </style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">113-120</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ledesma-Perez, F.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE GRAPHICAL REPRESENTATION REGISTER AS SUPPORT IN UNDERSTANDING CONCEPTS OF CALCULUS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">graphical representation register</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">November/2011</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://journals.indexcopernicus.com/abstract.php?icid=968806</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">35</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Students taking a calculus course for the very first time have generally had an intuitive approach to infinity, which has likely had to do with “real life” events, such as the infinite nature of the Universe. The students have not usually reflected upon any of the mathematics aspects of infinity and to a certain extent this hampers their understanding within a mathematical context. When learning about the concept of limit (essential in order to adequately build calculus concepts) knowledge of infinite processes is required. Moreover if the task of teaching calculus is restricted to its algebraic aspects without paying attention to the use of non-algebraic representations, it is very difficult for students to arrive at a deep understanding of calculus. It is even difficult to conceive of a student being able to comprehend calculus without having first developed visual skills tied in to building calculus concepts, for example.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">97-103</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Celeste  Ferreira</style></author><author><style face="normal" font="default" size="100%">Mónica Baptista</style></author><author><style face="normal" font="default" size="100%">Agnaldo Arroio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">VISUAL TOOLS IN TEACHING LEARNING SEQUENCES FOR SCIENCE EDUCATION</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">teacher education</style></keyword><keyword><style  face="normal" font="default" size="100%">visual tools</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2011</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://oaji.net/articles/2014/457-1408435793.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">37</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The accelerated development of information and communication technologies followed by several studies in the cognitive theory area, have promoted the use and the construction of many visual tools (3D concrete models, statics or dynamics virtual 2D and 3D images, simulations, animations, interactive software, etc) that have been available to educators. With this research it was aimed to investigate how in-service teachers (n=14) enrolled in a teachers’ training course of 40h, understand the nature and the role of visualizations in science teaching as well as the impact of this training. It was also discussed the nature and role of models in science. During the training teachers were invited to build in group teaching learning sequences (TLS) about some science content using visualizations. At the beginning a questionnaire to identify some previous conceptions on this issue have been applied and analyzed. On a later stage it was analyzed the TLS made by them and the audiovisual record of their oral communications to the class. It was also analyzed the final semi-structured interview with these teachers’ groups. As main results we highlight a development of the knowledge about these tools, especially on the impact of the visual language on apprenticeship and on the notion of scientific model. We could also observe a change on the reasons and criteria to use these tools. According to the findings it can be said that this training has expanded the teachers’ initial notion of models and the theoretical background that support the use of this visual resources which was reflected on theirs TLS.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">48-58</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Todar   Lakhvich</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">BEAUTYLITY OF CHEMISTRY VISUALIZATION: WHETHER USEFUL CAN BE AESTHETIC</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century </style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry education</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">March/2010</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1399917218.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">19</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The analysis of aesthetic potential of Chemistry visualization is carried out, taking in account philosophical, didactic, psychological and socio-cultural aspects. The issue is discussed in terms of the concurrent existence of two different subsystems referred both to Beauty and Utility which can be found in presentations of chemistry knowledge. To be aesthetic means the need to be accepted as attractive one, and thus Chemistry ought to change its paradigm to form new attitude to Chemistry knowledge. The concept can be regarded as for valuable acquisition (and thus very useful!) to learning process. To be useful means the need to be accepted as utile. The latter have been the main intention for the last centuries which turned the Chemistry into generator of the most unexpendable resources for industrial development. And it looks very attractive when people gained the highest plane of intelligence to admire the Beauty both natural and man-made objects. Finally both Beauty and Utility potentials derived from Chemistry visualization can be effectively elaborated within the integrated Philosophical Concept of Beautility. Theoretical study based on profound concepts from Science and Chemistry philosophy as well on few empiric researches carried out by author in the field of Chemistry Didactics.</style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">46-54</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Claudia  Ayres</style></author><author><style face="normal" font="default" size="100%">Celeste  Ferreira</style></author><author><style face="normal" font="default" size="100%">Agnaldo Arroio</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE USAGE OF A SIMULATION TO STUDY INTERMOLECULAR FORCES: SOME FINDINGS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century </style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">simulation</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2010</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://journals.indexcopernicus.com/search/article?articleId=2594528</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">24</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The purpose of this research was to discuss and reflect about the use of a computer simulation in the learning of intermolecular forces. Simulations are dynamic representations of chemical processes or systems, and allow users to select values for input variables from within suitable ranges and observe the results on output variables. In this study we used free software named “Ligações Intermoleculares”, from http://nautilus.fis.uc.pt/molecularium/pt/ligintermol/index.html. The goal of this activity was to help students build internal representations (mental models) for course content. The research is qualitative. We applied a pre-test and a post-test to a class of students (n=30) from a secondary school trying to find what these internal representations are like. The research indicates that students’ pictographic representations of intermolecular forces improved substantially. These findings suggest that the use of this visual tool helped students to make a better connection between the chemical representations and the macroscopic phenomena presented during a mini-course about solubility. </style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">19-29</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Renata Bilbokaitė</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">USE OF VISUALIZATION TO MOTIVATE SCIENCE AND GEOGRAPHY EDUCATION OF FEMALE SCHOOLCHILDREN</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century </style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">comprehensive school</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2010</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://journals.indexcopernicus.com/search/article?articleId=2594533</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">24</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">ICT progress and invasion in education started in post-modern age. The majority of schoolchildren tend to learn science and geography at a low level, there is a lack of specialists in scientific areas in the entire world. This research was done with the aim to identify whether visualization could stimulate female schoolchildren’s motivation in learning geography and science. A survey of 1934 schoolchildren, grades 9 and 10, from general and secondary schools was carried out. This paper focuses on data of female population. Obtained results suggest that visualization as a tool in general could be highly motivating for female schoolchildren, especially for those in grade 9, learning geography: they would like to learn new topics and be more active in lessons. It was also found out that visualization stimulates science learning by girls much more than their learning of geography. </style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">49-57</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Renata Bilbokaitė</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">STUDENTS’ SEARCH FOR VISUAL SCIENTIFIC INFORMATION: SITUATION ANALYSIS</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century </style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">science education</style></keyword><keyword><style  face="normal" font="default" size="100%">visualization</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">November/2009</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1396706598.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">16</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The modern visualization is created to help in education processes and it is oriented to the evaluation of knowledge. It is very important for science education to have perfectly prepared aids that could show invisible phenomena and could foster deeper motivation. This research encloses that students like to use internet for their purposes. The most important purpose is to use search for visualizations because students have aspiration for deeper knowledge. Also, results enclose negative aspects in this field. Students do not search for visual information in the internet because they feel lack of need; there are bad conditions in the classroom. The last reason could be identified as highlighted prominence of pedagogues’ role. All this could improve that students who have low interest to search in the internet could be called as unmotivated. </style></abstract><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">16-22</style></section></record></records></xml>
