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…

Microorganisms are ubiquitous in nature and are central to human, animal, environmental, and planetary health. They play a particularly important role in the food chain and the production of high-quality, safe, and health-promoting foods, especially fermented foods. This important role is not always apparent to members of the public. Here, we…

Science education is crucial for fostering knowledge across academic disciplines. Past efforts to enhance science achievement at the elementary level have explored various instructional strategies. Among these, the Understanding by Design (UbD) model has shown notable potential in improving science achievement outcomes compared to traditional…

The greenhouse effect is a complex scientific phenomenon that plays a crucial role in understanding climate change. Grasping students' understanding of this phenomenon on the content-specific level but also how students' conceptions are organized is vital for effective climate change education. This study addresses both levels and delves into the…

Researchers and educators have been exploring systems thinking (ST) in chemistry education to better equip citizens for 21st century challenges; however, little is known about students' perspectives and experiences. In this study, we investigated students' perspectives of ST and their experiences with ST activities. We designed and implemented a…

This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

A large number of students across the globe each year enroll in general chemistry courses as an academic requirement to obtain their degree. Although many take chemistry courses, it is not a subject sought out by many as a potential career. In some instances, chemistry hinders students from achieving their career goals. A plethora of chemical…

Citizen science has proven to be a useful paradigm both to contribute to science and to increase the public understanding of science. Thus the connection between citizen science and schools offers an interesting approach to explore. However, a lot of questions and challenges remain unclear, such as the balance between scientific and educational…

Using smartphones in experimental physics teaching offers many advantages in terms of engagement, pedagogy and flexibility. But it presents drawbacks such as possibly endangering the device and also facing the heterogeneity of available sensors on different smartphones. We present a low-cost alternative that preserves the advantages of…

Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

The 2019 "Minnesota Academic Standards in Science (Standards)" set the expectations for achievement in science for grades K-12 students in Minnesota. The standards are grounded in the belief that all students can and should be scientifically literate. Graduates should be prepared for career and college opportunities. The…

The 2019 "Minnesota Academic Standards in Science" (Standards) set the expectations for achievement in science for grades K-12 students in Minnesota. The standards are grounded in the belief that all students can and should be scientifically literate. The "Standards" describe a connected body of science and engineering…

We share a case study on our use of three reflective questions to demonstrate ways in which simple questions can be coded to reveal rich evidence of impact and engagement. At the end of a three-hour inclusive teaching practices workshop for 23 faculty and administrators from a single science department, 22 participants completed an anonymous…

Understanding why teachers teach the way they do is important especially in a time of curriculum reforms. Hence, the aim of this research is to unpack the secondary school physical science teachers' beliefs on the purposes and goals of science teaching (PGST) and to check the alignment of their beliefs on PGST with constructivism. A convergent…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…
