Öğe The Analysis of the Effects of Olfactive Stimulus in Learning in Context of Educational Technology(Elsevier Science Bv, 2013) Akpinar, Burhan; Ozdas, Faysal; Yildirim, Bilal; Batdi, VeliWhen the educational Technologies, which are used in the process of learning-teaching process, are associated with sensory organs, the least used one becomes the olfactive stimuli. Nowadays, because of being foreground of visual-audio Technologies, Positivism is based on vision and audition but it ignores the other senses. Although seeing and hearing play important roles, the ineffectiveness of other senses is delusion in this process. In this delusion the impact of visual-audio Technologic devices from telescope to television, internet, mobile phones is inevitable. However sensation and learning is wholistic and based on togetherness of five senses. Thus, with the delusion olfactive stimulus which is rejected from the educational field is effective on senses, attention, concentration and memory in learning. The purpose of this study, which is in form literature review, is to discuss the nature of olfactive stimulus the effectiveness in education, areas of usage in context of educational technology, to deduce and to make suggestions.

The data used in the study, which was carried out using survey model, was obtained through a questionnaire applied to 420 pre-service teachers studying pedagogical formation at Firat University. The data were analyzed using descriptive statistics techniques. In the study, it was discovered that teacher candidates had views similar to those defended by quantum and post-modern paradigm regarding the three basic dimensions of epistemological belief: source, certainty, and simplicity of knowledge. As for the dimension of the source of information, it was observed that male teacher candidates and Mathematics Department teacher candidates had more positivist views compared to others. Regarding the dimension of complexity of knowledge, female teacher candidates were closer to positivism, and as for the certainty of knowledge, teacher candidates from the departments of physics, chemistry and biology had views closer to quantum and post-modern epistemology.

This study has been carried out with 228 pre-service teachers. The participants were divided into three different experiment groups. Each experiment group was based on argumentation, problem or laboratory. The results of this work indicated that the argumentation-based learning method has advantages over its counterpart methods, although the laboratory-based learning method is more effective in comparison to the problem-based learning method.
