This article is a report on the findings of three case studies that focused on elementary teachers' in-the-moment noticing across a month of instruction. Extending Jacobs and her colleagues' framework (Jacobs, Lamb, and Philipp, 2010), this articles categorizes the mediums (i.e., written accounts, verbal interactions, physical strategies) by which…

In this paper we focus on variation of the design and the implementation of a specific task during three mathematics lessons in the 8th grade in a learning study (Marton & Tsui, 2004; Runesson, 2008). The theme of the lesson was division, with a denominator between 0 and 1. The teachers wanted their students to understand that when dividing…

Collaborative teaching is an option worth exploring at the elementary school level. The problem is many teachers lack the knowledge to effectively make these co-teaching relationships work. The purpose of this study is to identify effective co-teaching strategies to enhance collaborative teaching relationships. The study documents 1st through 4th…

This paper focuses on eight teachers nominated as effective in teaching reading to 11-13-year-old students. Data consisted of interviews and unstructured and structured observations of the guided reading lessons. The qualitative data and their analysis explored the research participants' views to give more detail and filter the quantitative…
