Developing mathematical practices in a social context: a hypothetical learning trajectory to support preservice middle school mathematics teachers’ learning of triangles
Uygun, Tuğba; Akyüz, Didem; Department of Elementary Education (2015)
The purpose of the current study was to document preservice middle school mathematics teachers’ (PMSMT) classroom mathematical practices emerged through six-week instructional sequence about triangles. In this respect, the research question of “What are the classroom mathematical practices that are developed within design research environment using problem-based learning for teaching triangles to preservice middle school mathematics teachers?” guided the present study. In order to answer this research quest...
Developing prospective teachers’ covariational reasoning through a model development sequence
Kertil, Mahmut; Erbaş, Ayhan Kürşat; Çetinkaya, Bülent (Informa UK Limited, 2019-2-8)
Forming part of a wider research study, the current study investigated prospective middle school mathematics teachers' ways of covariational reasoning on tasks involving simultaneously changing quantities. As the introductory theme of a larger unit on derivative, a model development sequence on covariational reasoning was designed and experimented with 20 participants in a mathematical modeling course offered to prospective teachers. The participants' developing abilities of covariational reasoning were doc...
Developing teacher learning progressions for K-12 engineering education: teachers’ attitudes and their understanding of the engineering design
Mesutoğlu, Canan; Baran Jovanovic, Evrim; Department of Educational Sciences (2017)
Teachers at the K-12 level have a critical role in including engineering in their instruction. More teachers who are equipped with the knowledge and skills necessary to teach science using the engineering design process are needed. Aiming to build tools to measure and track the progress in teacher’ attitudes and their understanding of the engineering design process suggested the use of learning progressions approach. The purpose of the study was to develop two teacher learning progressions for K-12 engineer...
