This paper presents Irish-medium immersion (IMI) teachers' perceptions of their development of content knowledge of language (CK-L) and pedagogical content knowledge of language (PCK-L) as a result of engaging in form-focused professional development (PD) which combined both content knowledge and pedagogical learning outcomes. An intervention,…

As young children increasingly use the Internet, the children need to learn and apply cybersecurity fundamentals to protect personal data. Teaching young students the basics of strong passwords and data protection in a K-12 classroom setting is an obvious starting point. The literature shows an absence of approved cybersecurity curriculums for use…

This study provided a springboard for teacher preparation evaluation studies by examining what content and pedagogical content knowledge mathematics pre-service teachers demonstrated in the 4-8 mathematics teacher preparation program at an urban research university. Twenty nine pre-service students participated in an assessment called Diagnostic…

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…

This study sought to identify components of an asynchronous online teacher professional development program, "Prime Online," that potentially affected participants' mathematical knowledge for teaching (MKT). Twenty-three third- through fifth-grade general education and special education teachers completed a yearlong online teacher…

This study explores the relationships between teacher knowledge, teaching practice, and student learning in mathematics. It extends previous work that developed and evaluated an innovative approach to assessing teacher knowledge based on teachers' analyses of classroom video clips. Teachers watched and commented on 13 fraction clips. These written…

This study examines the impact of a nationally disseminated professional development program, Developing Mathematical Ideas (DMI), on teachers' specialized knowledge for teaching mathematics and illustrates how such research could be conducted. Participants completing 2 DMI modules were compared with similar colleagues who had not taken DMI.…

There is considerable research on teachers' beliefs and teachers' knowledge, but little empirical evidence exists as to the interplay between them. This article reports a study of 356 Norwegian teachers who answered a questionnaire and a multiple-choice test. Based on this study, the connections between two knowledge constructs and two beliefs…

This report contains resources to help researchers and policymakers review measures used in NCEE evaluations of educational interventions. The measures included in the Compendium are applicable to settings for preschool through grade 12. The Compendium discusses criteria and their importance in selecting measures for assessing intervention impacts…

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 determine the competence of beginning California K-6 teachers in basic algebra topics, and to investigate their level of math anxiety and attitudes toward math. The sample for this study was beginning California elementary teachers in the Bay Area of California. An algebra content assessment and a self-report…

The Compendium discusses criteria and their importance in selecting measures for assessing intervention impacts…

This article begins to unravel the question, "What curricular materials work best under what kinds of conditions?" The authors address this question from the point of view of teachers and their ability to implement mathematics curricula that place varying demands and provide varying levels of support for their learning. Specifically, the…

The middle grades are in crisis. By state and national measures, student achievement gains realized in the elementary grades all too often diminish by grade 8. In most states, the considerable policy focus on high schools in recent years has not trickled down to a focus on the middle grades --yet preparation for "college- and work-ready standards"…

Sixty-five fourth-grade, fifth-grade and sixth-grade teachers in the Midwestern United States participated in professional development opportunities designed to increase their mathematics content knowledge and pedagogical knowledge over a two-year series of workshops. Through the use of pre-tests and post-tests assessing content knowledge and…
