Science education and research for technological progress

It is very important for science education to have perfectly prepared aids that could show invisible phenomena and could foster deeper motivation. Also, visualization as a learning and teaching tool could stimulate the perception. This leads to the opinion that represented objects could be shown in the classroom as essential part of education and its organization. Visualization in science as an essential teaching/learning tool has become of great importance nowadays because the technological progress is raising high require-ments for education. Problem question – whether computer based visualization stimulates cognitive process-es and what exact processes it activate? Research methods: analysis of information resources, questioning, qualitative method. Research methodology: model of genetic structural intellect, the theory of dual code, vis-ual thinking theory. Participants of the research. 209 schoolchildren from secondary schools participated in the research. Random sampling was chosen when schoolchildren in grades 9 and 10 had a possibility to par-ticipate in the research. The research instrument, a questionnaire with open-ended and closed questions, was designed. There were 209 schoolchildren (92 schoolchildren from grade 9, 107 – from grade 10) in the sam-ple. The respondents were about 14–17 years of age (2 schoolchildren–14 years old, 73 schoolchildren–15 years old, 111 schoolchildren–16 years old and 23 schoolchildren–17 years old). The respondents’ distribu-tion by gender: 72 girls and 45 boys of grade 10, 45 girls and 47 boys of grade 9. The results. Computer based visualization makes easier perception processes because it activates perception operations. Views in the screen help to compare details in visual form and to distinguish the main features. Also it helps to see objects in the whole objects and other things connected with them. All these facts help students to perceive visual information and to understand verbal one too. The results of the re-search enclose that computer based visualization help to memorize information. It is already known that it is easier to remember visual information and computer screen makes qualitative effect to the memory. At least, students reflect that computer based visualization helps to imagine things that are very abstract or difficult. According to students they are able to create images and mental models about phenomena when they see some similar analogs in the screen. To sum up, there could be done a prediction that computer based visuali-zation could foster deeper work of perception, memory and imagination. Key words: visualization, science education, cognitive processes.

Technology Trend

The technologies are expanding their possibilities in the global information age. The scholars aim to explicate perspectives of human power practice. Haptics technology is one of the ultimate technological trends. Visual culture and technological progress had speeded up the researches in this area. When possibilities to organize constructs of virtual reality have sprung up, the scholars had started discussion about the integration of haptic sense into information reception, conveyance and soak processes. It can be as the facility of studying and some performance of actions, to speed up technological progress. There are analyzing explorations in haptics technology trend (medicine, science education, robotic researches, computer science and experimental brain researches) in this article. The author is searching for connections between haptics technology ranges trends and technology adaptation for educational quality development. The subject of the research – researches in haptics technology trend. Aim of the research – to explore researches of haptics technology. The tasks of research are to single out the ranges, where haptics technology is generating in practice, to single out education range, where explorations and achievements of haptics technology is the most relevant, to ascertain the importance of haptics technology on the international ground aspect in science education context. Methods of research: metaanalysis, systemic structural analysis, comparative analysis. Results and conclusion: • Accomplished analysis shows that haptics technologies are generating practically in 5 ranges: medicine, science education, robotic researches, computer science and experimental brain researches. • It is ascertained, that the most achievements of haptics technology researches are in science education range. It is important to make more qualitative science education. The researches from Lithuania in this range are one of the leaders in the world (together with JAV, Korea). • Tactile is very important to visual-spatial perception development, this conditions haptics technology to give and to activate modulations in the human mental structure. The information and mental models are memorizing for longer period. Keywords: haptics technology, cyber researches, human brain researches, medicine, computer, science education.
