The Next Generation Science Standards (NGSS) have been imperative for informing many facets of the chemistry education research field, one of which includes the professional development (PD) of high school teachers. While many researchers and practitioners have responded to the NGSS' calls for reform by attending to internal factors that influence…

Despite years of research and practice inspired by chemistry education research, a recent report shows that US secondary instruction is not aligned with current national reform-based efforts. One means to mitigate this discrepancy is focusing on pedagogical conceptual change, its precursors (higher selfefficacy and pedagogical discontentment), and…

COVID-19 has thrust educators into a period of uncertainty, complicating conventional ways of teaching and learning. We suspect that the pandemic has magnified the challenges that some high school teachers already experience, particularly when they are the sole chemistry teacher at their school. The pandemic has likely inhibited collegial…

Researchers have typically identified and characterized teachers' knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of…

Specific to the topic of oxidation-reduction (redox), teachers are obligated by the discipline to prioritise symbolic traditions such as writing equations, documenting oxidation states, and describing changes (e.g., what undergoes oxidation/reduction). Although the chemistry education research community endorses connecting the vertices of…

College students associated with the American Chemical Society and Alpha Chi Sigma student/collegiate chapters reach almost 1 million people every year through their informal chemistry education events (chemistry outreach). Previous work has characterized their goals for chemistry outreach, with the most prevalent goal being audience learning.…

High school chemistry teachers will often establish goals that guide assessment design and interpretation of assessment results. However, little is known about how these goals and the assessment design collectively guide the interpretation of results. This study seeks to better understand what teachers notice when interpreting assessment results…

Even when chemistry teachers' beliefs about assessment design align with literature-cited best practices, barriers can prevent teachers from enacting those beliefs when developing day-to-day assessments. In this paper, the relationship between high school chemistry teachers' self-generated "best practices" for developing formative…

Designing high school chemistry assessments is a complex and difficult task. Although prior studies about assessment have offered teachers guidelines and standards as support to generate quality assessment items, little is known about how teachers engage these supports or enact their own beliefs into practice while developing assessments.…

Chemistry-specific informal science education (chemistry outreach) is widely practiced across all levels of the chemistry community. College students associated with American Chemical Society and Alpha Chi Sigma collegiate chapters are one population of chemistry outreach practitioners who reach upward of 1 million people every year. Previous…

Visualizations are useful tools for helping students to understand chemistry concepts at the particulate level. A classroom activity was developed based on learning theory and evidence-based practices, combining protein visualization with thermodynamic parameters from differential scanning fluorimetry (DSF) data analysis. Coding of student…

Implementation of the flipped classroom approach into STEM courses has been popularized in the last decade and has generally been reported to improve student performance outcomes. In a flipped classroom setting, students typically first encounter course content in the online format and subsequently engage in some form of active learning during the…

High school chemistry teachers struggle to use assessment results to inform instruction. In the absence of expert assistance, teachers often look to their peers for guidance and support; however, little is known about the assessment beliefs and practices of high school chemistry teachers or the discourse mechanisms used as teachers support one…

With the introduction of the Next Generation Science Standards (NGSS), curriculum and professional development have had to change rapidly to fit the new standards. To aid with those changes, the EQuIP rubric was released as a guide for NGSS alignment. This study aims to evaluate lesson plans developed through the Target Inquiry project to…

Informal chemistry education/chemistry outreach is ubiquitous with the chemical enterprise. However, little research has focused on the planning, implementation, or evaluation of these events. Results from a previous study suggest that college students involved with collegiate chapters of the American Chemical Society and Alpha Chi Sigma are…
