Pre-service Teachers Use of Visual Representation

Abstract: The purpose of this research is to evaluate the type and accuracy of the visual representations that the pre-service teachers generate in the pedagogical solution of the word problems. The data on participants' spatial competence levels were obtained through Purdue Spatial Visualization Test and the data on the type of visual representations were obtained by coding the data obtained from the solution of a word problem given to the participants. In the analysis of the data, descriptive analysis and content anal… Show more

“…Meanwhile, prospective teachers in the high ability category can correctly represent right triangles, unit circles, tables, and angular relations. The results of this study are in accordance with the results of previous studies which show that representation can help students solve math problems (Byers, 2010;Cooper & Alibali, 2012;Özsoy, 2018). However, the results of this study expand on the results of previous studies by explaining the representations used by prospective teachers in solving special angle trigonometric function problems based on ability categories.…”

“…Students' difficulties also relate to the division of geometric figures, the representation of fractions using the natural language register, the consideration of the part corresponding to the fraction of a figure, the change from one register to another, the representation of fractions using the graphical register and the interpretation of task instructions. These difficulties are evident because students make mistakes when responding, which must be discussed in order to overcome future difficulties, as pointed out by several authors (Kara & Incikabi, 2018;Canavarro & Pinto, 2012;Özsoy, 2018).…”

“…Mathematics learning depends on several factors (e.g., cognitive, social, cultural, and contextual) and on the different actors involved in the educational process, among which the role of the teacher is to be emphasized. Currently, recommendations for mathematics education indicate that students should be able to master the use of the different representations of rational numbers and not just memorize concepts (Barnett-Clarke et al, 2010;Canavarro & Pinto, 2012;Hodges et al, 2008;Kara & Incikabi, 2018;Özsoy, 2018;Scaptura et al, 2007). In order to enable familiarization with rational numbers, we need to represent them.…”

“…In this process, pictorial representations were the most helpful representations in constructing meanings of the mathematical objects under study, allowing them to express their reasoning more confidently and clearly, as they provided visual support that attenuated the abstract nature of the mathematical concepts and gave them meaning (Ozsoy, 2018).…”
