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 interactions and access to professional development (PD). Our reflections from redesigning a face-to-face PD program to one that is remotely delivered provide recommendations that advance PD accessibility and interactivity to mitigate isolation and other longstanding challenges teachers may face. In this article, we discuss how the cognitive learning model informed emergent teaching practices that guided the transformation of the PD’s implementation for 20 high school chemistry teachers.

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 such knowledge bases. However, lesson planning (defined as the transformation of subject matter knowledge to enacted pedagogical content knowledge) remains underexplored despite its central position in the RCM. We aim to address this gap by developing a conceptual framework known as Pedagogical Chemistry Sensemaking (PedChemSense).

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 the PD’s design, resources, and facilitation, there is less attention on extant factors that may negatively affect PD uptake and fidelity. Such factors encompass traditions of teaching chemistry or chemistry-related imprecisions within the NGSS themselves. If left unaddressed, these factors can act as anchors preventing advancements toward students’ particle-level explanations and their chemistry conceptual understanding. In this article, we investigate the uptake and fidelity of our own PD program known as the VisChem Institute.

Interview with Steve Roderick about helping teachers on the InquirySpace project bring more authentic science experiences to their classes.

A set of NGSS-aligned investigations for each discipline (physics, chemistry, biology) designed to introduce and scaffold engagement in science practices and build an understanding of the interplay between experimental design, data collection, analysis, and explanation. In the process of investigating their world, students generate data using traditional lab tools, sensors, and simulations, then bring their data into our Common Online Data Analysis Platform (CODAP), which was developed specifically to facilitate sensemaking with data.

In this paper, the relationship between high school chemistry teachers’ self-generated “best practices” for developing formative assessments and the assessments they implement in their courses are examined.
