    Preservice primary teachers' three dimensional thinking skills
    (ELSEVIER SCIENCE BV, 2009) Delice, Ali; Ertekin, Erhan; Yazici, Ersen; Aydin, Emin
    This study investigates primary school preservice teachers' abilities in relation to figures, one of the basic concepts of geometry, and more specifically, to name figures; to draw solid figures from their given corresponding nets and the nets from the solids; and to sketch a three-dimensional structure on the plane from a given perspective. The sample consisted of 62 year 1 and 119 year 3 students registered in the Primary School Education programme at Selcuk University, Education Faculty, Department of Elementary Education in the 2007-2008 academic year. The study had a survey research design and a test consisting of open-ended items was administered for data collection. Descriptive statistics and t-tests were used in data analysis. The results indicated that preservice teachers encountered difficulties in naming rectangular prism-square prism and rectangular pyramid-rectangular prism as well as in drawing these three-dimensional solid figures from their corresponding nets. Moreover, first year students achieved a higher average success rate than third year students. In their undergraduate studies, preservice teachers were not provided with opportunities to take part in the process via a curriculum which involves activities, materials and projects that develop spatial skills.

    Teacher Trainees' Epistemological Beliefs: Effects of Gender, Institution, and Discipline (Mathematics/Social Sciences)
    (WYDAWNICTWO ADAM MARSZALEK, 2009) Ertekin, Erhan; Dilmac, Buelent; Delice, Ali; Aydin, Emin
    How knowledge is acquired in various disciplines or the existence of other knowledge sources have been the focus of more recent research. Three types of knowledge have been specified in relation to the teaching of a discipline content, pedagogical and pedagogical content knowledge. Teachers and teacher trainees are expected to have expertise on these three knowledge areas. Within the process individuals develop epistemological beliefs. Little research exists which studies how similar/different mathematics and social sciences students are in terms of their epistemological beliefs. Therefore, the aim of this research was to investigate whether mathematics and social sciences teacher trainees differed in terms of their epistemological beliefs and if they did to test these differences with regards to certain variables. The sample consisted of mathematics and social sciences teacher trainees registered at four departments of two education faculties at two universities in Turkey. The data was collected using an 'Epistemological Beliefs Scale and a background information schedule. The results indicated gender differences in all three sub-scales of the epistemological beliefs scale. A difference in terms of discipline was also observed in the 'belief that learning depends on ability' factor of the epistemological beliefs scale.
