Effective K-12 integrated STEM education should reflect an intentional effort to adequately represent and facilitate each of its component disciplines in a meaningful way. However, most research in this space has been conducted within the context of science classrooms, ignoring mathematics. Also missing from the literature is research that examines the level of cognitive demand required from mathematical tasks present within integrated STEM lessons. In order to seek insight pertaining to this gap in the literature, we sought to better understand how science teachers use mathematics within K-12 integrated STEM instruction.

To address the lack of a classroom observation protocol aligned with integrated STEM, the author team developed one to measure the degree of integrated STEM instruction implemented in K-12 science and engineering classrooms. This study demonstrates how our instrument can be used to uncover the dimensions of integrated STEM instruction practiced in K-12 classrooms and to determine which protocol items are associated with each of these dimensions.

K- 12 Computer Science (CS) education is developing rapidly but still lacks a comprehensive measure for CS teachers’ pedagogical content knowledge (PCK). We respond to this need by describing the design of a CS-PCK instrument for ‘Algorithms and Programming’ that measures three broad constructs: (a) teachers’ understanding of standards and standards-alignment, (b) teachers’ formative assessment practices, and (c) teachers’ self-efficacy for teaching and assessing CS.

This position paper advocates supporting CS teacher professional learning by supplementing existing curriculum-specific teacher PD with standards-aligned PD that focuses on teachers' conceptual understanding of CS standards and ability to adapt instruction based on student understanding of concepts underlying the CS standards.

Research on geometric transformations suggests that early learners possess intuitive understandings grounded in motion metaphors, transitioning to mappings. The processes through which students transition between these two conceptions are not fully understood. We propose that Vygotskian hybridizing (related to Vygotsky’s articulation of everyday and scientific concepts) may provide a lens for thinking about the relationship between these conceptions.

It is essential for items in assessments of mathematics’ teacher knowledge to evoke the desired response processes – to be interpreted and responded to by teachers as intended by item developers. In this study, we sought to unpack evidence that middle school mathematics teachers were not consistently interacting as intended with constructed response (i.e. open-ended) items designed to assess their pedagogical content knowledge (PCK).

Science teacher leaders have been identified as an important lever for the implementation of science education reform. However, science reform implementation is locally controlled and not uniform across districts; therefore, the work of STLs within a reform context can vary. In this descriptive case study, we explore the work of 11 science teacher leaders who support science education reform in a variety of organizational contexts. Through the analysis of multiple data sources, we describe the roles that these science teacher leaders take up in their work and identified how variation in these roles related to localized contexts and priorities for science education.
