A collaborative effort by policymakers and researchers designed an experiential learning program to empower preuniversity chemistry teachers to integrate Sustainability and Green Chemistry principles into their curricula using case-based learning (CBL) strategies. Eighteen teachers from 17 schools participated in a workshop and a site visit to…

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…

Boston teachers boost their skills and student proficiency through peer observation and collaboration. The observation is the anchor activity for a learning site, a professional learning series designed to support teachers in making instructional improvements aligned with self-identified needs and districtwide instructional goals. Learning sites…

In the United States, the Next Generation Science Standards advocate for the integration of computational thinking (CT) as a science and engineering practice. Additionally, there is agreement among some educational researchers that increasing opportunities for engaging in computational thinking can lend authenticity to classroom activities. This…

There is an overwhelming consensus that sustained opportunities for teachers' professional learning is critical for student success, but due to the COVID-19 pandemic, the nature, substance, and format of K-12 teachers' opportunities for professional learning necessarily shifted. District administrators, focused on maintaining the safest possible…

The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these…

Although most teachers recognize the importance of taking investigative, open-ended approaches to students' learning experiences, implementing them in high school classes can be challenging for teachers. In this work, we analyzed data from multiple sources from a teaching Community of Practice (CoP) to investigate (a) barriers to taking an…

Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

Teaching green chemistry within the K-12 classroom has a positive impact on attitudes and perceptions of chemistry in society for future scientists and professionals, resulting in safer, less hazardous chemistry experiments and demonstrations. The state of New York has taken advantage of the benefits that green chemistry provide in the classroom…

Purpose: The authors are developing a model for rural science teacher professional development, building teacher expertise and collaboration and creating high-quality science lessons: technology-mediated lesson study (TMLS). Design/methodology/approach: TMLS provided the means for geographically distributed teachers to collaborate, develop,…

International science education reforms seek to support teachers in using everyday assessment to draw out and work with student ideas; however, developing these instructional practices requires time and support. This paper investigates how a professional development program supported high school chemistry teachers to learn about formative…

High school science teachers are a unique subset of teachers with distinctive PD needs in content, pedagogy, and technology, yet there is scant research about PD from the perspective of secondary science teachers. This qualitative research study used narrative research methods with grounded theory to explore how a group of seven high school…

In science education, educators frequently encounter the challenges of inadequate resources, equipment, and pedagogical strategies when planning and executing science projects in classrooms. To address this pervasive issue, forty-one science teachers participated in a training workshop to acquire expertise using Arduino microcontrollers and…

The article analyses teachers' learning on the use of multiple representations (MRs) in the teaching of Ohm's law, examining them in a lesson study, structured in 18 meetings of 2.5 hours each, that addressed this physics curricular topic for the 3rd grade of high school. The qualitative research involved four teachers who teach physics in…

Teachers' goals and orientations underlie their instructional decision making and can make the difference between "talking the talk" and "walking the walk" when trying to change lab instruction. Schoenfeld's "Resources, Orientations, and Goals" (ROG) framework was employed to shed light on the challenges involved in a…
