One of the unique advantages of electrochemistry is that the relationship between thermodynamics and kinetics is quantitative, which is the basis of voltammetry. Mathematical models of electrochemical systems take advantage of this relationship to predict the effect of changing a system property (e.g., concentration, scan rate, or rate constant)…

This laboratory experiment showcases electroless deposition, an autocatalytic reduction process performed in aqueous solution containing a metal ion in the presence of a reducing agent yielding a coherent metal film. One set of experiments has been performed by second-semester general chemistry students in a 3 h lab session. After preparing an…

Integrating knowledge across disciplines has been shown to be a challenging, and yet it is a necessary skill that university students need to develop. Students who are able to connect different concepts, perspectives, and angles of a given topic are generally more engaged and have better understanding. However, designing lesson plans or…

A robust laboratory protocol for the three-step synthesis of "p"-tolyl 2,3,4,6-tetra-"O"-benzoyl-1-thio-[beta]-d-glucopyranoside from commercial glucose pentaacetate is reported. The previously reported procedures have been modified to accommodate laboratories and students without proper training or equipment needed to conduct…

Constructing and critiquing evidence-based claims is centrally important to aspiring medical professionals and to scientists more generally. Accordingly, The National Academy of Science's "Framework for K-12 Science Education" describes engaging in argument from evidence as one of the practices that characterize work in science. However,…

Researchers have shown students develop misconceptions in projectile motion for various reasons. A common misunderstanding among first-year high school physics students is the notion that the horizontal and vertical components are interchangeable in projectile motion. The students' incorrect reasoning is connected to their personal experiences…

This article investigated the influence of age and gender on class attendance as well as Chemistry Education students' academic achievement in SED 281, at the University of Calabar. Descriptive survey research design was employed for the study. The target population was two hundred and twenty Chemistry Education students in the Department of…

Anatomical education is very important in understanding the internal structure of the body and the mechanism of life, especially for the medical profession, including nursing. However, in Japan, students have a few opportunities of getting anatomical education using animals before they enter university. The different step-by-step anatomical…

Wetlands are defined as areas of soil saturated with standing water. These areas are rich in biodiversity, containing numerous plants, animals and microorganisms. Wetlands act as natural filtering systems for runoff and can improve the water quality in an area. To demonstrate the importance of wetlands to a nonscience major introductory…

Spatial understanding of molecules in molecular biology provides a better understanding of molecules in isolation and relation to their next elements. Augmented reality (AR) has recently been developed as a computer interface that enables the users to see the real world with virtual objects superimposed on it. We report a method that shows the use…

Chemistry-specific informal science education (chemistry outreach) is widely practiced across all levels of the chemistry community. College students associated with American Chemical Society and Alpha Chi Sigma collegiate chapters are one population of chemistry outreach practitioners who reach upward of 1 million people every year. Previous…

A laboratory experiment has been developed to illustrate the transformation of silver nanoparticles (Ag NPs) in water containing phosphate anions. The experiment, conducted by high school students, involved hands-on learning to synthesize and characterize Ag NPs via ultraviolet-visible (UV-vis) spectroscopy. This was followed by a UV-vis probe of…

In a two-step synthesis starting with Ni(CH[subscript 3]COO)[subscript 2] ·4H[subscript 2]O and salicylaldehyde, students prepare Nethyl and N-isopropyl Ni(II) Schiff base (imine) complexes. After isolation and recrystallization, the products are characterized by room-temperature magnetic susceptibility measurements, FTIR spectroscopy, and…

Two-stage collaborative testing is an assessment strategy that involves students initially writing a test individually and then immediately afterward writing the same (or similar) test again in groups. Current evidence shows that two-stage testing improves performance on multiple-choice tests as well as short-term retention of material, but little…

The VSEPR model has well-established limitations in its ability to represent accurate molecular and electronic geometries of simple molecules, which can create a significant need for students to relearn structure and bonding concepts in organic chemistry. We present an alternate method for describing molecular geometries and electronic structures…
