Developing Mathematical Practices In A Social Context:An Instructional Sequence To Support Prospective Elementary Teachers', Debra Wheeldon
Developing Mathematical Practices In A Social Context:An Instructional Sequence To Support Prospective Elementary Teachers', Debra Wheeldon
Electronic Theses and Dissertations
This teaching experiment used design-based research (DBR) to document the norms and practices that were established with respect to fractions in a mathematics content course for prospective elementary teachers. The teaching experiment resulted in an instructional theory for teaching fractions to prospective elementary teachers. The focus was on the social perspective, using an emergent framework which coordinates social and individual perspectives of development. Social norms, sociomathematical norms, and classroom mathematical practices were considered. A hypothetical learning trajectory (HLT) including learning goals, instructional tasks, tools and imagery, and possible discourse, was conjectured and implemented in the mathematics class.

A Study Of An Attempt To Improve The Reliability Of Teachers' Holistic Scores Of Elementary Writing Through In-House Profess, Lisa Farmer
Electronic Theses and Dissertations
This study evaluated the effectiveness of a school-based training that attempted to improve the reliability of holistic scores teachers assigned to the writings of elementary school students. Seventeen teachers at one suburban elementary school located in the Southeastern United States participated in three training sessions that allowed for scoring practice and group discussions. The trainers, or presenters, were "faculty-experts." A comparison of scores the participants assigned to students' writings before and after the training was conducted. The analyses included t-tests that compared the participants' mean scores to the scores assigned by raters from the state, a within-group analysis of reliability …
