Özet |
This study aimed to propose a meta-classification for middle school students' selections of quadrilaterals in terms of trapezoid. Data were collected from thirteen seventh grade students via a trapezoid selection instrument and semi-structured interviews. Data analyses were executed by using thematic coding of qualitative research methods by synthesising past and current theories about teaching geometry (figural concepts, concept image-definition, prototypical phenomenon etc.). Meta-classification was characterized considering the types of students' selections, concept images, and errors through seven special categories. This meta-classification shaded light on how students conceive a shape as trapezoid, what they notice their selection procedure and what influences their selections for trapezoids. |
