In this study we extend our prior exploration focused on the extent to which middle school teachers appropriately identified proportional situations and whether there were relationships between attributes of the teachers and their ability to identify proportional situations. For this study, we analyzed both a larger dataset (n = 32) and two…

This report provides a description of a cognitive interview study investigating validity of assessments designed to measure "content knowledge for teaching" (CKT). The report is intended both to provide information on the validity of the CKT measures and to provide guidance to researchers interested in replicating the design. The study…

Researchers have recently used traditional item response theory (IRT) models to measure mathematical knowledge for teaching (MKT). Some studies (e.g., Hill, 2007; Izsak, Orrill, Cohen, & Brown, 2010), however, have reported subgroups when measuring middle-grades teachers' MKT, and such groups violate a key assumption of IRT models. This study…

Profile analyses were used to investigate differences in the self-efficacy growth of teachers with more and less mathematics background as the teachers participated in professional development across two summers. Professional development activities were associated with increases in teachers' self-efficacy; however, without considering mathematics…

Teacher preparation programs face great challenges in ensuring their graduates are prepared for the demands of today's classrooms. The authors explore how teacher accountability has evolved based upon federal legislation leading to adoption of the Common Core State Standards (CCSS). Recognizing that future teachers will be held accountable for…

The purpose of this study was to explore one Indiana elementary teacher's perceptions of her Latino immigrant students as they become English-language proficient by providing an in-depth analysis of a 4th and 5th grade teacher at a local school. Findings are based on interviews with the focus teacher and with the personnel she works with such as…

The research article in this article is part of a larger study that examines an initiative to expand teacher expertise in facilitating mathematical problem solving within the framework of developing and field-testing pedagogical resources. We focus on one year of the study and report on the complex process of professional development as teachers…

The purpose of this study was to investigate and describe how middle school mathematics teachers "make meaning" of proofs and the process of proving in the context of their classroom practices. A framework of "making meaning," created by the researcher, guided the data collection and analysis phases of the study. This framework…

In a paper published in "The Language Learning Journal" in 2005, Eric Hawkins describes his vision of language education as an apprenticeship comprising two stages. In stage one (ages 5-14), the purpose is "educational" and the focus is on language awareness; in stage two (14-19), the purpose is "instrumental" and…

An evaluation mosaic brings together different methods and forms to present an overall picture of the impact this professional learning experience had on teachers' practices and on student achievement. Using this framework, professional developers were able to determine whether they were getting the results they wanted--and they did.
