Science teacher candidates’ perceptions about roles and nature of scientific models

Background: Scientific models have important roles in science and science education. For scientists, they provide a means for generating new knowledge or function as an accessible summary of scientific studies. In science education, on the other hand, they are accessible representations of abstract concepts, and are also organizational frameworks to teach and learn inaccessible facts. As being indispensable parts of learning and doing science, use of scientific models in science classes should be reinforced. At this point, uncovering pre-service science teachers’ (PSTs) understandings of scientific models are of great importance since they will design and conduct teaching situations for their students. Purpose: The study aimed to provide an answer to the research question: What understandings do PSTs possess about scientific models? Sample: The sample of the study consisted of 14 PSTs enrolled in an Elementary Science Education program in a public university in Ankara, Turkey. Design and methods: Data were collected by using an open-item instrument and semi-structured interviews, and were analyzed by using qualitative data analysis methods. Results: Findings showed that PSTs held fragmented views of models by having informed views in some aspects while having naïve views on others. That is, although they displayed a constructivist orientation by acknowledging the presence of multiple models for the same phenomenon depending on scientists’ perspectives or creativity involved in the production of scientific knowledge, PSTs also expressed logical positivist views by believing that models should be close to the real phenomena that they represent. Findings further revealed that PSTs generally conceptualized models’ materialistic uses, yet they did not think much about their theoretical and conceptual uses. It was observed that roles like reifying and visualizing were overestimated and models were dominantly characterized as three-dimensional representations. Conclusions: It is clear that PSTs, having difficulties in grasping the concept of models, would possibly have problems in planning their lessons effectively and would not develop accurate concepts in their students. These findings apparently support the need for appropriate pedagogic training of PSTs to scientifically reflect on and professionally make use of models in science classes.     

Educating Turkish Primary School Teachers in Visual Arts: the Past and the Future

Every educational system should meet certain criteria that establish quality in teaching and learning. These criteria are often provided by aims and objectives listed in school curricula. After describing and commenting on the history of school education in Turkey, the main question posed in this research is how to change the Turkish primary school education in visual arts so that its quality will improve. After analysing the situation, this work provides an outline of how this may be achieved. In the future, the insights gained may be very useful for an incorporation of European standards into the Turkish educational system.     

Reinforcing contingencies for sex-role behaviors in preschool children

Two groups of disadvantaged Afro-American children, a total of 30 boys and 25 girls, mean age about 42 months; and two groups of middle- and upper-middle-class children, most of them white, 35 boys and 31 girls, mean age about 44.5 months, were observed for patterns of sex-role-characteristic behavior and peer and teacher response to such behavior. At all times, the children in the two experimental groups were being taught by seven women and seven or eight men, about half of whom were Afro-American, half white-Anglo, and who were mixed in the two schools by race but evenly divided by sex. Boys engaged in 16% sex-characteristic behavior, 5.7% cross-sex behavior. The same figures for girls were 18 and 6%. There were no pattern or percentage differences by race or social status of children. Women teachers gave most of their sex-role connected rewards for feminine behavior to both boys and girls. Men teachers rewarded more equably, masculine behaviors for boys, feminine behaviors for girls. Children rewarded mainly their own sex, and gave rewards for sex characteristic behavior. The pattern was even clearer for boys than for girls. In Discussion, comparisons are made with other somewhat similar studies.     

Discourse as Representation of Design Thinking and Beyond: Considering the Tripod of Architecture–Media,Education, & Practice

Discourse is often considered as a taken-for-granted notion, however, it is already a representational genre of design thinking whether written/ unwritten, spoken/unspoken, designed/ undesigned, realised/unrealised. This article explores current architectural discourse to understand its relations with the design thinking transmitted through various modes of representations in media, education and practice, and to find out how such discourse might implicitly influence design ideas. The article argues that discourse, in this context, will stand as a product in itself in architectural culture. Moreover, a cross-view of today's architectural discourses will inform us about the present state of architecture, how contemporary architects express themselves or communicate from such points of view, and what might be the emergent issues and possibilities in architecture and design representation.
