In a nationwide initiative to increase computer science Education in K-12, many teachers were recruited to CS teaching positions but without adequate preparation, which can lead to lack of confidence and feelings of isolation [35, 54]. In response to these issues, the purpose of this study was to determine the effectiveness of a newly developed…

This study aimed to explore the relationship between science teachers' pedagogical content knowledge (PCK) of argumentation, epistemological beliefs, and classroom practices. Participants were three urban science teachers who were selected among 12 teachers from a professional development (PD) program focusing on Argument-Driven Inquiry (ADI)…

Teacher professional development (PD) is seen as a promising intervention to improve teacher knowledge, instructional practice, and ultimately student learning. While research finds instances of significant program effects on teacher knowledge, little is known about how long these effects last. If teachers forget what is learned, the contribution…

This national study of 1858 teachers participating in professional development(PD) summer programs in the United States encompasses a wide range of science subjects and grades. It was conducted to identify program features associated with increases in two types of teacher knowledge that are goals for most professional development programs: teacher…

The field of computer science continues to lack diverse representation from women and racially minoritized individuals. One way to address the discrepancies in representation is through systematic changes in computer science education from a young age. Pedagogical and instructional changes are needed to promote meaningful and equitable learning…

We present results from a meta-analysis of 95 experimental and quasi-experimental pre-K-12 science, technology, engineering, and mathematics (STEM) professional development and curriculum programs, seeking to understand what content, activities, and formats relate to stronger student outcomes. Across rigorously conducted studies, we found an…

How should teachers spend their STEM-focused professional learning time? To answer this question, Heather Hill, Kathleen Lynch, Kathryn Gonzalez, and Cynthia Pollard analyzed a recent wave of rigorous new studies of STEM instructional improvement programs. They found that programs work best when focused on building knowledge teachers can use…

Reflecting growing emphasis on data analysis and statistical thinking in the information age, mathematics curriculum standards in the U.S. have recently increased expectations for student learning in the domain of statistics and probability. More than 180 teachers in 36 public school districts in Florida applied for a two-week summer institute…

This article presents an in-depth study supporting the Scientist in the Classroom Partnership (SCP) program as a model of effective professional development (PD) for K-12 teachers. The goal of this study was to determine the core and structural features of the SCP program necessary for effective teacher PD. The SCP partners a classroom teacher…

In an effort to address K-8 teacher confidence in STEM and increase basic genetics knowledge to a level consistent with its importance in society, we have developed, implemented, and evaluated a 7-day teacher professional development workshop. The overarching goal of our workshop is to facilitate the implementation of innovative DNA-based…

The Teacher Academy in the Natural Sciences (TANS) provided middle school (U.S. Grades 6-8) teachers (N = 81) with intensive professional development in chemistry, geosciences, and physics through 13 days of face-to-face instruction that was extended with 2 online science modules per discipline. Because we administered online module assessments…

Over a decade ago, Borko (2004) raised the awareness of the education research community to the critical need for studies of teacher professional development (PD) programs. She states on page 13: "My challenge to the educational research community is this: We have much work to do and many questions to answer in order to provide high-quality…

Drawing from the historical lens of cultural memory, I examined the development of three social studies pre-service teachers' African American history knowledge. The participants were engaged in a rigorous summer reading program dedicated to learning African American history. This qualitative case study examined both pre and post interpretations…

This article explores a two-year professional development initiative with four state geographic alliances. Professional development planners, whether planning for a large- or small-scale initiative or one with unlimited or limited funding, will benefit from learning about this successful professional development activity and how the impact in the…

An Earth science professional-development program for in-service middle- and high-school teachers increased participants' content knowledge about weather, climate, and climate change in addition to increasing their confidence in their assessment and teaching skills. The curriculum and funding gave them time, funding, and the help of content and…
