Daisuke Kajiya – Journal of Chemical Education, 2023
The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

Janet L. Shaw – Journal of Chemical Education, 2023
Assessments that are open-ended and student-centered may be used to encourage formation of networks between prerequisite material and new course content thereby promoting meaningful learning. Creative Exercises (CEs) are assessments that allow multiple correct answers and do not penalize for incorrect statements thereby inspiring creativity. CEs…

Anne de Poulpiquet; Neso Sojic; Laurent Bouffier; Alexander Kuhn; Dodzi Zigah – Journal of Chemical Education, 2023
Electrochemistry is taught in most undergraduate chemistry programs. Although this topic is important for students due to its broad interest in industry (energy, diagnostics, car industry, etc.), they often find it difficult, because it is based on a combination of various physical concepts such as electric fields, interfacial processes or charge…

Steven M. Drew; Tristan Belzer – Journal of Chemical Education, 2023
The construction and characterization of a glucose biosensor has been implemented in an instrumental chemical analysis course to provide students experience with chemical sensing, electroanalytical methods, and flow injection analysis (FIA). The glucose biosensor was assembled on a glassy carbon electrode by depositing a layer of Prussian blue…

Kurt Bodenstedt; Jacob L. Fripp; Shan Li; Zhou Lu; Mohammad A. Omary; Molly B. Atkinson – Journal of Chemical Education, 2023
An advanced research discovery laboratory course in inorganic chemistry has been developed to engage undergraduate students in authentic research experiences directly related to concepts and theory taught in the lecture portion of the course. The 12-week laboratory involves an initial 4 weeks of training experiments on inorganic/organometallic…

Yada Nolvachai; Junaida Shezmin Zavahir; Riley Herron; Philip John Marriott – Journal of Chemical Education, 2023
An approach to online laboratory exercises for analytical chemistry students with demonstrated practical exercises through the use of remote-controlled gas chromatography (GC) instrumentation is discussed. The approach allows for a practical-based learning activity to be carried out by students who are unable to attend in-person laboratory…

Plastic waste is a growing concern in recent years due to the massive increase in single-use plastic applications. Despite the ever-increasing amount of waste, recycling plastics is not a simple process due to difficulties in sorting, which results in significantly downgraded material properties. This hands-on lab experiment showcases the…

Celia Maya – Journal of Chemical Education, 2023
Chemistry and biochemistry instructors must help students to develop the ability to visualize and manipulate 3D biomolecular structures and critically analyze them and their relationship to their functions. To do this, representative systems must be strategically selected to stimulate students' motivation. Since the World Health Organization…

Ross Andrew Shalliker; Corey Manwaring – Journal of Chemical Education, 2023
Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

Applications of machine learning in chemistry are many and varied, from prediction of structure-property relationships, to modeling of potential energy surfaces for large scale atomistic simulations. We describe a generalized approach for the application of machine learning to the classification of spectra which can be used as the basis for a wide…

Shannon L. W. Accettone; Cassandra DeFrancesco; Cole Alexander King; Monique K. Lariviere – Journal of Chemical Education, 2023
Laboratory skills assignments were developed as a novel approach to providing students with the opportunity to engage in hands-on laboratory skills development outside of the lab during the COVID-19 pandemic. Initially, the assignments were implemented within a second-year forensic chemistry course of 48 students and redesigned and modified to be…

Jakub A. Konkol; George Tsilomelekis – Journal of Chemical Education, 2023
Preprocessing is a critical step in the analysis pipeline of spectroscopic data. However, students are rarely introduced to preprocessing when learning spectral techniques in laboratory courses which in turn may affect and delay their progress in the field. Despite its undoubtable importance, students will be mainly performing spectroscopic…

Amber M. Hupp – Journal of Chemical Education, 2023
In this paper, a problem set activity focused on understanding and applying unsupervised and supervised chemometric methods for the analysis of biodiesel-diesel blended fuels is described. This problem set was utilized in two upper-level analytical elective courses aimed for junior and senior level students. The data set consists of peak areas…

Rajesh Viswanathan; Nirmala Krishnamurthy – Journal of Chemical Education, 2023
Active learning strategies engage students productively in the process of learning through problem-solving activities and discussions, over and above the routine method of listening passively to the instructor. This work highlights the redesign of a medicinal chemistry course by augmenting traditional lectures with active learning sessions in…

Muhammad Rais Zulfianto; Muhammad Abduh – Elementary School Forum (Mimbar Sekolah Dasar), 2023
Misconceptions are understandings of concepts that are not in accordance with scientific concepts. Teachers have the potential to experience misconceptions and misconceptions that occur in teachers can result in students also experiencing misconceptions. Research that examines science misconceptions in elementary school teachers is still rare, so…
