Teacher enthusiasm is known to affect students' learning in traditional classroom environments, but it is unclear how displayed teacher enthusiasm can optimize learning of chemistry procedural knowledge in multimedia learning environments. In this context, the present study used eye-tracking technology and quantitative analysis to examine how…

Our goal was to understand how students' chemistry learning environments changed and how students responded to the wholesale transition to online learning. We deployed surveys to students enrolled in nine undergraduate chemistry courses at all levels. Survey 1 was deployed 2 weeks post-transition (N = 208); Survey 2, a week before semester's end…

London dispersion forces (LDFs) are the most fundamental of the noncovalent interactions in that they are interactions that act between all molecular species and require only that students can use the "electron cloud" model of atomic structure. In this longitudinal study we investigate how students respond to prompts, designed to elicit…

In the Just-in-Time Teaching approach, a faculty member assigns readings to students before every class. After the students have done the daily reading, they access a short reading quiz using a course management system (e.g., Moodle). The faculty member uses student responses to the quiz in the preparation of the day's class material and is able…

Molecular model kits have been used in chemistry classrooms for decades but have seen very little recent innovation. Using 3D printing, three sets of physical models were created for a first semester, introductory chemistry course. Students manipulated these interactive models during class activities as a supplement to existing teaching tools for…

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,…

Variable temperature NMR spectroscopy is used to determine the ?H° and ?S° of hydrogen bond formation in a simple diamide. In this two- or three-day experiment, students synthesize N,N'-dimethylmalonamide, dimethylsuccinamide, dimethylglutaramide, or dimethyladipamide from methylamine and the corresponding diester (typically in 50% recrystallized…

Organic chemistry problems that interrelate and integrate synthesis with spectroscopy are presented. These synthesis-spectroscopy roadmap (SSR) problems uniquely engage second-year undergraduate organic chemistry students in the personal discovery of organic chemistry. SSR problems counter the memorize-or-bust strategy that many students tend to…

Road map problems ask students to integrate their knowledge of organic reactions with pattern recognition skills to "fill in the blanks" in the synthesis of an organic compound. Students are asked to identify familiar organic reactions in unfamiliar contexts. A practical context, such as a medicinally useful target compound, helps…

Although the effectiveness of student response systems in improving student learning is inconclusive, clickers can be used to create a positive learning environment in the classroom, which can help increase student achievement. With the use of clickers, students showed modest improvements in their performance in conceptual summative assessments.…

Peer instruction is an active-learning pedagogy in which students answer short, conceptually based questions that are interspersed during instruction. A key element is the group discussion that occurs among students between their initial and final answers. This study analyzes student responses during a modified form of peer instruction in two…

As active members of the scientific community, graduate students make ethical judgments about the conduct and presentation of their research. Pressures in the research environment often influence these decisions. Because inappropriate decisions can lead to unethical behavior and scientific misconduct, it is important that students understand the…

An initial goal of chemistry laboratory courses is almost always the "proper" use of laboratory resources including glassware and instruments. The proper use of glassware encompasses many topics, such as laboratory safety, technical proficiency, and recognition of function. However, as many chemical educators can attest, at both the K-12 and…

Two complementary techniques to gauge student understanding and inspire interactive learning in the chemistry classroom are presented. Specifically, this article explores the use of student responses with their thumbs as an alternative to electronic-response systems and complementing these experiences with longer, task-based questions in an…

This paper describes an upper-level undergraduate and graduate-level course on computers in chemical education that was developed and offered for the first time in Fall 2007. The course provides future chemistry teachers with exposure to current software tools that can improve productivity in teaching, curriculum development, and education…
