Reforms in STEM education call for reframing teachers' pedagogical content knowledge (PCK) by focusing on development of students' knowledge and scientific literacy through socioscientific issues (Lee, 2016; Zeidler, 2016; Johnson et al., 2022). We developed a two-year professional development (PD) for 6-12th grade STEM teachers that embedded SSI…

Globally, fewer students are choosing careers in science. In developing countries like Bangladesh, this attrition is often attributed to limited access to laboratories, lack of qualified science teachers, and limited use of student-centered strategies (SCS). Educators are attempting to design professional development programs to empower teachers…

This paper explores the effect teachers' participation in a targeted inquiry-based/nature of science (NoS) continuing professional development programme had on Irish primary children's experiences of scientific inquiry and developing conceptions of NoS. Data were gathered from 459 children from 10 Dublin schools. The findings revealed that their…

The National Aeronautics and Space Administration (NASA) is one of the United States' leading federal science, technology, engineering, and mathematics (STEM) agencies and plays an important role in the landscape of STEM education. In 2015, NASA's Science Mission Directorate (SMD) created the Science Activation (SciAct) program to increase the…

The purpose of this study was to examine the design, implementation, and initial outcomes of a collaborative professional development program intended to prepare middle and high school educators to implement effectively the Next Generation Science Standards (NGSS) in classrooms with diverse learners. The professional development program discussed…

The newly adopted Next Generation Science Standards (NGSS) requires that California secondary science teachers integrate global climate change (GCC) content into their curriculum, but research reveals major inconsistencies in teaching GCC content across the nation. The teaching inconsistencies are due to factors such as the lack of scientific…

Despite the importance of the theory of evolution (TE) to scientific knowledge, a number of misconceptions continue to be found among biology teachers. In this context, the first objective of this study was to identify the impact of professional development programme (PDP) on teachers' understanding of nature of science (NOS) and evolution and on…

This study investigates the effect of a Framework-aligned professional development program at the PreK-3 level. The NSF funded program integrated science with literacy and mathematics learning and provided teacher professional development, along with materials and programming for parents to encourage science investigations and discourse around…

Reform efforts that are designed to increase student achievement often include in-service teacher professional development (PD) as a foundational component. However, the content and activities included in PD sessions varies greatly. Guided by Desimone's (2009) Core Features of Professional Development, this study sought to describe agriscience…

This dissertation serves as a call to geoscientists to share responsibility with K-12 educators for increasing Earth science literacy. When partnerships are created among K-12 educators and geoscientists, the synergy created can promote Earth science literacy in students, teachers, and the broader community. The research described here resulted in…

The goal of this study was to assess the effectiveness of an intervention--Quality English and Science Teaching 2--designed to help English language learners (ELLs) and their English proficient classmates develop academic language in science, as required by the Common Core State Standards. The intervention consisted of supplementary instructional…

This study examined the effects of professional development integrating academic literacy and biology instruction on science teachers' instructional practices and students' achievement in science and literacy. The intervention consisted of 10 days of professional development in Reading Apprenticeship, an instructional framework integrating…
