Instructors in STEM classrooms often frame students' interactions with technologies to help them learn content. For instance, in many STEM domains, instructors commonly help students translate physical 3D models into 2D drawings by prompting them to focus on (a) orienting physical 3D models and (b) generating 2D drawings. We investigate whether…

The plan view is used in crystallography and materials science to show the positions of atoms in crystal structures. However, it is not widely used in teaching general chemistry. In this contribution, we introduce the plan view, and show these views for the simple cubic, body-centered cubic, face-centered cubic, hexagonal close packed, CsCl, NaCl,…

This commentary summarizes the authors' basic disagreements with the paper, "Rabbit-Ears, VSEPR Sterics, and Other Orbital Anachronisms," which criticizes the authors' usage of the hybrid orbitals for H[subscript 2]O in their book, "A Chemist's Guide to Valence Bond Theory" (Shaik and Hiberty, 2008). The current article shows…

In this study, secondary school students' (N?=?617; grades 7 to 10) understanding of models and modeling was assessed using tasks which explicitly refer to the scientific disciplines of biology, chemistry, and physics and, as a control, to no scientific discipline. The students' responses are interpreted as their biology-, chemistry-, and…

Learning model in Kazakhstani Universities is being focused on transforming education from teacher-centered to student-centered approach. This transformation requires academic staff retraining and a significant modernization of educational process. In this article we discuss issues of methodological readiness of academic staff for student-centered…

This paper investigates the frequency and contextual uses of the metadiscoursal devices of evidentials, code glosses, hedges and boosters in four academic disciplines, namely, linguistics, literature, chemistry and medicine. Hyland and Hinkel's taxonomies of metadiscourse provided the search items. The data analyzed consisted of a corpus of forty…

This qualitative study sought to explore Malaysian novice chemistry teachers' experiences in teaching mixed-ability students during their teaching practicum, focusing on their instructional strategies for dealing with those learners in the class. The researchers employed purposive sampling to select 12 trainee teachers to be involved in…

To help ESP college instructors improve the English curriculum taught at polytechnic institutes, colleges and universities, the current study proposes a model for designing English for Polytechnic Purposes (EPP) courses for undergraduate students majoring in mechanical engineering, chemistry, technology, economics, textile industry and other…

This book has been prepared to introduce common technological tools that can be used in science education in the distance education process. Although most of the applications introduced in the book are used in face-to-face education, this book focuses on their use in the distance science education process. In the Introduction part of the book, the…

Cheminformatics is a widely used interdisciplinary field that is important for many chemistry areas. Cheminformatics skills are necessary for dealing with a large amount of chemical information and are considered essential for various tasks such as data analysis, visualization, storage, etc. This paper presents the basic cheminformatics chemistry…

We present a case study of the transition from a face-to-face course to an emergency remote course to a successful online course at the University of Puerto Rico, a Hispanic Serving Institution that has faced economic and natural disaster hardships during the past few years. We discuss the selection of free-of-cost and accessible technology…

This article reports the results of a curriculum survey of 322 analytical chemistry instructors (92% U.S.-based) conducted during Spring 2021. This snapshot of current course formats, topics, and pedagogical methods will be useful to both seasoned and novice teachers of analytical chemistry. The majority of respondents reported that their major…

Teaching chemistry to nonscience majors is challenging because most students come to class with negative beliefs about chemistry. Those mindsets stem from their inaccurate prior knowledge of how chemistry relates to their daily lives. To address the issues and promote students' engagement in chemistry courses, we implemented ubiquitous biodiesel…

The mass shift to Open-Book, Open-Web (OBOW) assessments during the pandemic highlighted new opportunities in Higher Education for developing accessible, authentic assessments that can reduce administrative load. Despite a plethora of research emerging on the effectiveness of OBOW assessments within disciplines, few currently evaluate their…

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…
