Research in astronomy education has uncovered that many learners possess limited and fragmented understanding of stars. The corresponding misconceptions manifest in various areas such as star formation, size, the relationship between stars and planets, and their position in space and have been shown to persist across different age groups and…

Online laboratories can be an effective way to introduce students to lab concepts while providing flexibility, increased access, and reduced costs. However, online labs might lack the authentic research experience that can be gained by doing hands-on lab work. This study explores student perceptions of an online, inquiry-based introductory biology…

This study employed a word association test to determine middle school students' cognitive perceptions and misconceptions of the key concepts regarding "cycles of matter and environmental problems." The study adopted descriptive research in survey model. The sample consisted of 457 eighth-grade students from four middle schools…

Although much research exists of students' alternative conceptions about evolution and natural selection, the way in which these vary in time and how scientific explanations change during instruction remains to be described and understood. Therefore, the main objective of this research is to characterise the nature of the change in student…

This report describes a laboratory experiment for an undergraduate-level inorganic chemistry or biochemistry course involving the study of the kinetics of the catecholase activity of a synthetic nickel­(II)-oximate complex. A model substrate, 3,5-di-tert-butylcatechol(DBC), undergoes aerobic oxidation to 3,5-di-tert-butylbenzoquinone (DBQ) in the…

The eChem project features an e-book published as a web page (10.30746/978-91-988114-0-7), collecting a repository of Jupyter notebooks developed for the dual purpose of explaining and exploring the theory underlying computational chemistry in a highly interactive manner as well as providing a tutorial-based presentation of the complex workflows…

This article reports the development of Chem'Sc@pe, an escape game activity for first- and second-year undergraduate students, covering various topics from an introductory organic chemistry course. The objective was to encourage them to review notions learned in class in a fun and collaborative environment. The set comprises a game board…

An increased reliance on nanotechnology and recent developments in materials fabrication coincide with a greater prevalence of 3D printers in high schools. We developed this lesson to foster an exploration of interdisciplinary fields and to increase access to recent advances in materials chemistry through two different learning modules. The lab…

The chemical experiment is designed for undergraduates majoring in chemistry, energy, and environment. The intended purpose is that the students will comprehend the reaction mechanism of photocatalytic reduction of CO[subscript 2] through hands-on experiments and deepen their understanding of sustainable energy technologies. More importantly, the…

Discussion is a vital component of the scientific process and dialogic learning opportunities support student learning gains and scientific epistemic learning. Discussions can improve connections between concepts and support student engagement which can increase retention in STEM programs. It has also been reported that a correlation exists…

The essential component of expanding an undergraduate curriculum is the inclusion of lab experiments in nanoscience and nanomaterials, which significantly impact health and the environment through their use in food, cosmetics, agriculture, and medicine. We designed a laboratory experiment based on the atomic force microscopy (AFM) analysis of the…

Students in an animal physiology course are required to have completed prerequisite cell biology and genetics courses that include discussion of basic properties and functions of the cell membrane. However, while many students remember basic information about membrane structure, they often have difficulty relating that structure to membrane…

In both general chemistry and analytical chemistry courses, students are introduced to the concept of predominant species in solution when discussing acid/base chemistry. Speciation diagrams are often used to illustrate the concept and predict the relative abundance of species in solution. Herein, we describe a laboratory experiment for an…

A Fourier transform infrared (FTIR) experiment appropriate for an upper-level undergraduate laboratory such as chemical instrumentation is described. Students collect FTIR spectra of four protio-solvents and their deuterated analogues. In addition to qualitatively observing C-H and O-H peaks shift to lower energy upon deuteration, students apply a…

Organic reaction trajectories show atomic motion and molecular reorganization of reactants during a single product-forming collision. iORA is a free (available from the Apple App Store), easy to use, highly interactive iPhone application that provides on-the-fly 3Drendering of organic reaction trajectories calculated with density functional theory…
