This conceptual analysis paper discusses the characteristics of teacher leadership (TL) in Science, Technology, Engineering, and Mathematics (STEM) education, presenting benefits for its development within the professional learning communities (PLCs). We describe our STEM education approach and argue that TL in STEM is different and more complex than leadership in any particular discipline. We compare two pathways for STEM learning and professional development (PD): engineering design approach and modeling approach. Then, we answer two research questions pertaining to the characteristics of STEM teacher leaders' (TLRs) knowledge, dispositions, and skill set; the support TLRs need to empower STEM educators; and consequently, we discuss how PLCs can become vehicles for growing STEM TLRs and empowering teachers. When promoting integrated STEM, educators likely find themselves in an out‐of‐field teaching situation, where communication with their PLC's leaders and peers is crucial in developing epistemological multiliteracy and confidence. We elaborate on the four main characteristics of STEM PLCs: (1) collaborative nature; (2) focus on boosting teachers' pedagogical content knowledge and confidence; (3) evidence‐based decision making; and (4) advocacy for high‐quality STEM education, teacher education, and PD. Each feature serves different but complementary goals, suitable for developing and utilizing the seven dimensions of TL discussed in the literature. [ABSTRACT FROM AUTHOR]

Increasing demand for high‐quality STEM education calls for the formation and retention of effective educators with STEM expertise; yet endeavors to meet this demand require organizational structures and supports that can overcome the lack of collective understanding around STEM education, limited STEM knowledge by leadership, and mounting teacher attrition. STEM teacher leadership is one mechanism for addressing this challenge by empowering excellent classroom teachers with opportunities to institutionally shape STEM learning, without extracting them from their instructional role. This paper offers a STEM teacher leadership framework that targets teachers' identity development toward an equity‐focused, transformational STEM teacher leader. First, we examine the field of teacher leadership (both STEM‐specific and generally) to provide a foundation for the areas of potential impact by STEM teacher leaders, as well as dispositions and stances that support their emergent leadership. Complementing the literature, we explore and elevate aspiring STEM teacher leaders' perspectives, drawn from baseline surveys and interviews of a multi‐year professional development program for middle grade teachers in STEM disciplines. The framework, iteratively informed by these sources, includes our stance on equity in STEM education, eight dispositions, and four domains of knowledge and practices that shape STEM teacher leadership in K‐8 school settings.

This paper details a literature review of mathematics vocabulary intervention studies for students with mathematics difficulty. The primary aim was to identify instructional practices that support mathematics vocabulary development. We conducted a database search to identify mathematics intervention studies either focused exclusively on vocabulary or with an embedded vocabulary component. Ultimately, 13 studies with participants from kindergarten to Grade 8 were included in the review. The majority of included studies had dual foci on vocabulary and other mathematics content, including whole number computation, word problem solving, fractions, algebra, or geometry. All studies that measured mathematics vocabulary performance indicated positive student outcomes. In addition, multiple studies indicated positive effects on measures of other mathematics content beyond mathematics vocabulary knowledge. We noted six instructional practices across studies that bolstered the mathematics vocabulary performance of students with mathematics difficulty. From most to least common, these practices included formal vocabulary use, explicit instruction, use of representations, repeated exposures, pre‐teaching, and graphic organizers. Implications are addressed for both researchers and practitioners. [ABSTRACT FROM AUTHOR]

Science teachers play a vital role in the education of students and their learning outcomes. Beyond academic performance and content knowledge, how one feels about science can influence how they teach and how students learn. It is important for educators, and teacher educators to reflect on their past experiences and decipher what experiences influence their overall perceptions about science. Mixed methods were used to analyze narrative papers from pre‐service teachers which focused on their science education experiences. Papers from one hundred undergraduate early‐childhood pre‐service educators were used to determine factors that influence pre‐service teachers' overall perceptions about science. Results indicated that negative experiences at all stages of students' k‐12 education diminished positive perceptions of science; meanwhile, corresponding effects related to positive experience were sourced only from high school. Similarly, negative teacher experiences resulted in diminished positive perceptions of science without corresponding effects of positive teacher experiences. Learning approach and informal learning experiences did not predict positive perceptions of science, but were relevant within the qualitative analysis. Implications are discussed for pre‐service teacher training programs. [ABSTRACT FROM AUTHOR]
