Chile is home to most of the world's largest telescopes, and astronomy research is robust in the country. However, astronomy education in Chile is much less mature. As an effort to increase its quality and coverage, more astronomy K-12 teacher professional development (PD) has been offered in Chile in the last decade, but the results of these…

Teacher candidates kept journals for one semester, documenting the science content and practices they encountered in their daily lives, while their professor provided detailed written feedback. The objective of this study was to determine gaps in everyday science practices, and to eventually design interventions which might help teacher candidates…

Effective questioning and discussion are fundamental instructional skills for science teacher candidates to master. These skills are important for teacher competence that aids student achievement. Opportunities to practice these skills in traditional teacher preparation programs may be limited. This embedded single case study focused on an…

The purpose of this research is to examine the effect of a summer camp-based science methods course on elementary pre-service teachers' self-efficacy in teaching science as inquiry. The science camp was offered to K-6 students as part of the 4-week, 3-credit science teaching methods course over the summer. The pre-service teachers were asked to…

There is a growing need for science educators and communicators who can support public understanding of complex science issues. Furthermore, little is known about how to nurture career aspirations for teaching science. This study examined the influence of youth volunteer experiences on career aspirations through a lens of science identity.…

In rural, geographically dispersed school districts, access to high-quality face-to-face professional development (PD) is challenging. Our study developed and compared the effectiveness of an online PD for middle-school science teachers working in remote, rural areas of Kansas with an evidence-based traditional face-to-face PD with the goal of…

In the last 30 years, there has been an ongoing discussion about the effectiveness of Professional Development (PD) programs, which aims to promote reform-based Science Education (SE). Among the many, different trends of reform-based science teaching, inquiry-based approaches hold a dominant role. This study shows how teachers' practices were…

Research has highlighted the significant decline in teachers' implementation of newly acquired teaching practices following professional development (PD), primarily attributed to the absence of follow-up support. Even science teachers who have participated in intensive PD programs often encounter challenges in integrating new teaching practices…

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…

If the declines in interest and performance within school science are to be reversed, it is imperative that competent and confident teachers deliver quality science experiences. This paper reports on the long-term implementation of two complementary, student-centered tertiary science methods courses that integrated instruction in content with…

This article focuses on the impacts of a program designed to prepare elementary classroom teachers to mentor preservice teachers for effective science instruction. The mentor preparation program was grounded in research on effective science instruction and learning-focused mentoring. The goals of the mentoring professional development were to (a)…

The purpose of this phenomenological case study was to study how secondary school science teachers describe their lived experiences of professional development (PD) in Punjab (Pakistan). The study included 15 secondary public school science teachers using purposive sampling from Punjab. Semistructured, in-depth phenomenological interviews were…

Providers of K-12 in-service teacher science professional development programs (PDPs) in the United States are moving to address recent and unprecedented policymaker calls to close achievement gaps in K-12 science learning. Our systematic review of primary, peer-reviewed equity-focused PDP studies is intended to inform this movement. We structured…

This study investigated the impact of a summer institute with follow-up coaching (treatment) versus no professional development (control) on middle and high school teacher and student science practice outcomes. Treatment teachers participated in a 2-week summer institute that used evidence-based professional development practices followed by…

Prospective teachers perceive peer coaching as a supportive learning opportunity providing benefits in peers' engagement in active learning, communicative competences, and critical thinking about teaching. Little is known about whether peer coaching also promotes the development of pedagogical content knowledge (PCK) in teacher education, which is…
