Pedagogical approaches for supporting students' argumentative writing in science laboratories have not been fully established. This article examines the development of argumentative abilities in undergraduate students enrolled in chemistry laboratory courses that employed two teaching sequences: (i) an argumentative writing workshop for conceptual…

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…

Redox reaction is a core concept in teaching and learning chemistry. This article explores a new method for balancing organic redox reactions that requires the balancing of both atoms and charges. The H+, O, H[subscript 2]O, and e- are used as balanced vehicles in two half reactions. A non-oxidation number approach can be applied to both molecular…

This article provides two additional mnemonics that can serve to help undergraduate students recall how to apply the rules of writing net ionic equations. These mnemonics were incorporated into dozens of lecture and laboratory class content, which includes hundreds of undergraduate (health professions and physical science major) students. As a…

Success for students majoring in STEM (science, technology, engineering, and mathematics) within undergraduate chemistry courses is crucial for retention in science degree programs, especially for students perceived as lacking content knowledge and skills. This study leveraged blended learning structures in a remedial chemistry course combined…

Passive, lecture-based forms of instruction are often ineffective in helping students develop deep conceptual understanding of scientific concepts. Student-centered forms of instruction based in a constructivist framework, where students are guided toward actively constructing their understanding, have been met with greater success. However,…

Recent calls for reform in K-16 science, technology, engineering, and mathematics (STEM) education not only emphasize mastery of content, but also call for students to engage in the scientific practice of making evidence-based claims, or scientific argumentation (National Research Council, 2012; NGSS Lead States, 2013). However, students often…

Introductory science courses serve a population of students in the major (i.e., chemistry) as well as those students outside the discipline (i.e., premed, biology, engineering). In an effort to help this diverse population of students connect personally with the content of the course, we sought ways to include student-centered activities, provide…

The intermolecular forces activity presented in this article is designed to foster concept-building through students' use of concrete, manipulative objects, and it was developed to be pedagogically sound. Data analysis via pre- and posttesting and subsequent exam questions indicated that students who had the opportunity to participate in the…

Preservice teachers enrolled in a modified introductory chemistry course used an instructional rubric to improve and evaluate their understanding of students' misconceptions in learning various chemistry concepts. A sample of 79 preservice teachers first explored the state science standards to identify chemistry misconceptions associated with the…

Access to state-of-the-art instrumentation, namely nuclear magnetic resonance (NMR) spectroscopy, early in the college curriculum was provided to undergraduate students in an effort to improve student perceptions of science. Proton NMR spectroscopy was introduced as part of an aspirin synthesis in a guided-inquiry approach to spectral…

Demonstrations are used in chemistry lectures to improve conceptual understanding by direct observation. The visual aid described here is designed to demonstrate the change in state of matter with the change of temperature and the change of pressure with temperature. Temperature is presented by the rate of airflow and pressure is presented by…

Diagrams and figures play a central role in science and science education. Research has indicated that, when presented and used properly in a classroom setting, these external representations can contribute to students' understanding of scientific concepts; however, it is apparent that students do not always use, understand, interpret, or value…

This case study uses a daily cooking scenario to demonstrate how the boiling point of water is directly related to the external pressures in order to reinforce the concepts of boiling and boiling point, apply ideal gas law, and relate chemical reaction rates with temperatures. It also extends its teaching to autoclaves used to destroy…

An interdisciplinary team of science and education faculty at the University of Illinois at Chicago and several Chicago-area community colleges developed and implemented a series of four integrated, inquiry-based science courses for preservice elementary school teachers. All four courses are based on guiding principles taken from the rich…
