Formative assessment can facilitate teachers’ abilities to elicit and notice the disciplinary substance of students’ thinking and to respond based on this. Following a design-based process, we developed principled practical knowledge to create resources that might guide experienced teachers in examining their formative assessment practice and provide researchers with tools to study formative assessment enactment.

Teachers face challenges when building the concept of substance with students because tensions of meanings emerge from students’ daily life and canonical ideas developed in classrooms. A powerful tool to address learning, pedagogical, and research challenges is the conceptual profile theory. According to this theory, people employ various ways of conceptualizing the world to signify experiences. Conceptual profiles are models of the heterogeneity of modes of thinking and speaking about a given scientific concept which are used in a variety of contexts.

A powerful tool to address learning, pedagogical, and research challenges is the conceptual profile theory. According to this theory, people employ various ways of conceptualizing the world to signify experiences. Conceptual profiles are models of the heterogeneity of modes of thinking and speaking about a given scientific concept which are used in a variety of contexts. To better understand the heterogeneity of thinking/speaking about substance, the present study aimed to answer: (1) What are the zones that constitute the conceptual profile of substance?; and (2) What ways of thinking and speaking about substance do teachers and students exhibit when engaged in a classroom formative assessment activity?
Learning and learning goals in undergraduate chemistry laboratory have been a popular research topic for the past three decades due to calls for curriculum reform, cost justification, and overall efficacy of necessary skill development. While much work has been done to assess curricular interventions on students’ learning and attitudes towards lab, few have discussed the increased difficulties of these non-traditional laboratory activities or the obstacles students must overcome in the laboratory setting.
The work presented here focuses on student struggles in undergraduate general chemistry laboratory activities, the source of these struggles, and the actions students take to overcome them. Using an activity theoretical lens and multiple domains (cognitive, epistemological, socioemotional, and psychomotor), we developed a domains-of-struggle framework which encompasses how struggles emerge through contradictions within the laboratory activity system.
Chemical scientists and engineers are interested in controlling chemical processes to attain specific goals, from synthesizing a desired substance to hindering a particular transformation. Nevertheless, students typically have few opportunities to develop the understandings and practices that are required to effectively engage in chemical control. In this study, we investigated similarities and differences among individuals with different levels of expertise in chemistry in the ways they think about how to control and act to control a chemical reaction.

Teaching chemistry as a practice rather than as a mere collection of facts demands that teachers modify their practices, particularly their approach to formative assessment (FA). In this study, we investigated how teachers’ FA practices changed as a result of their participation in a professional development program designed with a Chemical Thinking perspective. Four FA portfolio chapters were collected from 19 secondary school teachers over the course of a year.

The effective use of formative assessment (FA) has been demonstrated to confer positive impacts on student learning. To understand why and how FA works, it is necessary to characterize teachers’ FA practices, but because both teaching practice and learning depend on the nature of the discipline, there are disciplinary aspects to examining this. This study aimed to develop an analysis of chemistry teachers’ FA practices through the lens of the chemical thinking framework.
Formative assessment is an important component of teaching as it enables teachers to foster student learning by uncovering, interpreting, and advancing student thinking. In this work, we sought to characterize how experienced chemistry teachers notice and interpret student thinking shown in written work, and how they respond to what they learn about it. Drawing on qualitative methods from different educational fields, we analyzed data collected during focus groups of middle and high school teachers.

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).
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.

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).
