HIGHLIGHTS
- who: Yi et al. from the College of Education, Texas Tech University, Lubbock, TX, USA have published the research work: Measuring pre-service elementary teachers’ geometry knowledge for teaching 2-dimensional shapes, in the Journal: (JOURNAL)
- what: Identifying specific kinds of mathematical knowledge teachers need to support student learning and measuring such knowledge reliably and This study examined the psychometric properties of the GKT-2D scale using modern test theory techniques. This study is developed to identify geometry content and pedagogical content knowledge for teaching 2dimensional (2D) shapes at the elementary level through a literature . . .
