Outreach initiatives are typically framed as informal learning environments that provide an opportunity to increase the participants' interest in science. Research on chemistry outreach has primarily focused on designing and implementing demonstrations for outreach. Recent studies indicate student organizations are at the forefront of chemistry…

The unit factor method, a generic strategy for solving any proportion-related problem, is known to be effective at reducing cognitive load through unit-cancellation providing step-by-step guidance. However, concerns have been raised that it can be applied mindlessly. This primarily quantitative prepost study investigates the efficacy of…

Teachers' responses to student contributions in science classroom influence the resulting classroom interaction. To establish a heightened interaction, teachers need to use specific discursive moves. Using the notion of noticing as a lens, in this qualitative case study, I report on how the notion of noticing and responding with a suitable…

Integration of computational data science (CDS) into the university curriculum offers several advantages for students, faculty and the institution. This article discusses the benefits to students of introducing CDS into the university curriculum with a focus on developing skills in cheminformatics, data analysis, structure--activity relationships,…

During the pandemic, the use of question pools for online testing was recommended to mitigate cheating, exposing multitudes of science, technology, engineering, and mathematics (STEM) students across the globe to this practice. Yet instructors may be unfamiliar with the ways that seemingly small changes between questions in a pool can expose…

Can online learning strategies in general chemistry work as well as learning in an on-site classroom? As the COVID-19 pandemic restrictions eased in 2022, a cohort of first-year Chemistry majors took a general chemistry lecture course in hybrid mode: learning activities were undertaken online using a flipped classroom approach, while formal…

To enhance students' learning and help them understand the whole picture of the field of inorganic chemistry, an inorganic laboratory technique course was designed that uses scaffolded, inquiry-based lab experiments and project-based learning. The scaffolded, inquiry-based laboratories taught in the first 8 weeks of the course helped students…

The redesign of the first year basic chemistry course is described at the Rotterdam University of Applied Sciences Chemical Engineer educational course. This was done with the aim to reduce student drop-out during the first year of the educational program. On one hand, it was chosen to teach the basic chemistry course in the laboratory where…

Chemish - the scientific language of chemistry - is crucial for learning chemistry. To help students acquire the competencies to understand and use Chemish, chemistry teachers need to have a sound knowledge of teaching and learning Chemish: Pedagogical Scientific Language Knowledge (PSLK). But still, despite the importance of this knowledge, the…

Student giftedness is a complex, developmentally dynamic and contextual phenomenon that teachers confront every day. In the classroom, teachers often meet students who have exceptional potential or achieve very high learning goals. The aim of this study is to illustrate the evaluation of inquiry-based learning activities in a specific context…

The joint virtual global learning activity brought together college students from Jordan and New York City to learn about United Nations Sustainable Development Goal (UN SDG) #6 and explore the issues of water pollution and drinking water quality in both regions. The activity involved undergraduate students from Guttman Community College and…

The ACS CHED Committee on Computers in Chemical Education (CCCE) ran the first intercollegiate OnLine Chemistry Course (OLCC) on Environmental and Industrial Chemistry in 1996, and is offering the seventh OLCC on Cheminformatics and Public Compound Databases: An Introduction to Big Data in Chemistry in 2017. This Communication summarizes the past,…

Making optimal pedagogical and predictive use of the radius ratio rule to distinguish between solid state structures that feature tetrahedral, octahedral and cubic holes requires several updated insights. A comparative analysis of the Born-Landé equation for lattice energy is developed to show that the rock salt structure is a suitable choice for…

Iron metabolism is an important subject of study for undergraduate students of chemistry and biochemistry. Relevant laboratory exercises are scarce in the literature but would be very helpful in assisting students grasp key concepts. The experiment described here deals with different iron release mechanisms of two protagonists in iron metabolism:…

On the basis of the model of the interactive relationship between teachers and curriculum materials, this research proposed the four dimensions of the interaction of chemistry teachers with curriculum materials: 'routine use', 'scientific inquiry', 'STSE' and 'teacher learning'. An instrument with good validity and reliability was developed.…
