Gamification has a strong track record of improving student engagement and learning in the chemical sciences. Meta-analyses of different approaches to gamification have highlighted that providing a game fiction, encouraging students to work in teams, and breaking games into smaller "quests" are particularly effective. Here, we aimed to…

With many universities now admitting students into their science programs with little or no prior knowledge of the relevant field, significant challenges arise in the way these fields are introduced. Challenges mount with various preconceived ideas regarding the levels of difficulty, thus necessitating introductory concepts be presented in…

Hands-on experiences in analytical chemistry laboratories are essential to improve students' technical skills on handling analytical glassware and instruments, but the coronavirus pandemic in 2020-2021 disrupted such learning activities. Thus, alternative remote activities are required to supplement practical skills. In this work, a new portable…

General chemistry II is often a challenging course for first-year STEM students, and many students rely on partial credit to achieve success in the course. However, assigning liberal partial credit to students' work can also disincentivize developing proficiency with the material. Here, we present an alternative specifications-based grading scheme…

Student performance on open-response calculations involving acid and base solutions before and after instruction in general chemistry and analytical chemistry courses was compared with the output from the artificial intelligence chatbot ChatGPT. Applying a theoretical model of expertise for problem solving that includes problem conceptualization,…

Transforming the chemistry curriculum to an interdisciplinary perspective is essential for preparing students to meet interdisciplinary career demands and to brace themselves for the challenges of complex environmental and health issues. The study introduces four interdisciplinary electrochemistry STEM-lab activities as an alternative to the…

Over the last decade, the demands on secondary science teachers have shifted to encompass a new range of objectives. Science teachers need support in their efforts to be responsive as they navigate shifting demands in the teaching profession: new state standards, an ever-diversifying student body, and a drive to integrate social justice into…

In the laboratory, data acquisition systems are important, as they allow us to easily and precisely collect data. In this sense, Arduino emerges as an automatic data acquisition device with great potential, due to its low cost and high versatility. In this work, we describe the development of an experimental apparatus, with automatic data…

During the time of the COVID-19 pandemic, online teaching was implemented by teachers in almost all education areas, and various technological tools were also employed to improve teachers' online teaching effectiveness. Based on this, the current qualitative case study aims to explore chemistry teachers' experience during online teaching in…

In addressing the need for safer and more accessible chemistry lab procedures, this work integrates green chemistry and small-scale chemistry concepts to serve as a laboratory model for both qualitative and quantitative analyses of iron(III). An aqueous extract of Indian gooseberry is utilized as a natural reagent to form a complex with iron(III),…

This study used a three-phase design to explore how teachers' views and practices of scientific inquiry can be reconciled with early graders' ability to engage in scientific inquiry. First, 19 early years teachers were interviewed to explore their views and practices of scientific inquiry. Second, six standard two students were exposed to a…

Improving students' STEM competencies is important and relies on fine-grained assessments, however, assessing scientific inquiry in an authentic, automated way is challenging for a number of reasons. Here, we provide an overview of how the learning sciences and computational sciences were used in the design and development of Inq-ITS and its…

BrainPOP Science is a research-based program that has been shown to be effective in improving and quickly developing students' scientific reasoning skills. This white paper presents a comprehensive case study conducted in school districts in the Southeastern United States. BrainPOP Science is one of the leading supplemental middle school programs.…

This dissertation asks how to improve science education and science communication, and suggests that digital storytelling techniques can be used to better engage learners in the process of knowledge making. Digital storytelling refers to both the use of high-quality digital media content as learning materials, and also to the use of social…

The frequently used analogy of a massive ball distorting an elastic sheet, which is used to illustrate why mass causes spacetime curvature and gravitational attraction, is criticized in this article. A different analogy that draws on the students' previous knowledge of spacetime diagrams in special relativity is suggested.
