A simple one-dimensional [superscript 1]H NMR experiment that quantifies protein bound to gold nanoparticles has been developed for upper-division biochemistry and physical chemistry students. This laboratory experiment teaches the basics of NMR techniques, which is a highly effective tool in protein studies and supports students to understand the…

A comprehensive experiment for third-year undergraduate students in pharmaceutical engineering is described. Students had previously completed courses in analytical chemistry, chemistry of natural products, and bioseparation engineering and had background knowledge in purification, quantitative analysis, packed column chromatography,…

Infrared (IR) thermography renders invisible infrared radiation with intuitive coloration in images and videos taken of objects, reactions, and processes. Educators can take advantage of this technology to extend students' sensory perception of chemical reactions or processes that absorb or release heat in rich detail. In theory, IR thermography…

General chemistry and introductory chemistry students were presented with a laboratory exploration for the determination of the mass percent of copper in rock and mineral samples. They worked independently in the laboratory, which involved multiple lab (pipetting, preparing standard solutions by quantitative dilution, recording visible spectra…

The development of novel, high-yielding, and selective methodologies for the asymmetric synthesis of stereocenters is at the forefront of modern synthetic chemistry research. Organocatalysis can now be viewed as a viable alternative to the use of the sometimes toxic transition-metal catalysts. In this experiment, the simple synthesis of an achiral…

In this article, a bomb calorimeter experiment and subsequent calculations aimed at determining the strain energy of the cyclobutane backbone are described. Students use several butanol isomers instead of the parent hydrocarbons, and they manipulate liquids instead of gases, which makes the experiment much easier to perform. Experiments show that…

The generation of secondary colors in digital devices by means of the additive red, green, and blue color model (RGB) can be a valuable way to introduce students to the basics of spectroscopy. This work has been focused on the spectral separation of secondary colors of light emitted by a computer screen into red, green, and blue bands, and how the…

Experimental skills should be acquired by learners at school and university alike. To promote experimental skills, various approaches exist within a spectrum between implicit and explicit instruction. Regarding these instructional approaches, numerous findings are available which predominantly relate to pupils. It is an open question whether it is…

Multiple pedagogical approaches, such as experimental experiences or computer-based activities, have been shown to increase student learning and engagement. We have developed a laboratory module that includes both a traditional "live" experimental component and a student-designed "virtual" computer simulation component. This…

When conducting biological investigations, experts constantly integrate their conceptual and quantitative understanding of variation with the design and analysis of the investigation. This process is difficult for students, because curricula often treat these concepts as separate components. This study describes the effect of a curricular…

In this study that aims to motivate struggling students and helping them to improve their learning achievement, we designed and tested an E7-based approach in a virtual laboratory environment. We rely on cognitive load theory and self-determination theory to enable our approach to meet the cognitive and noncognitive needs of struggling students.…

This article provides an overview of a summer professional development (PD) for teachers working within an urban alternative educational school district. Engaging with a lab classroom with intensive coaching support, teacher participants observed and participated in 20 days of literacy instruction that centered culturally responsive-sustaining…

We present data displaying course-based undergraduate research experiences (CUREs) effectiveness in providing authentic cutting-edge research experiences to undergraduates, which both private and government organizations recognize as essential. A total of 68 students were enrolled in this research with 50 students being in a traditional laboratory…

With the relatively recent technological advances, Multi-User Virtual Environments (MUVEs) have become a promising venue for education; however, little is known about their effective implementation in the classroom. This paper addresses this gap by investigating the creation, implementation, product and evaluation of an instructional design using…

An essential goal for physics and optical science instructors is to encourage students to find excitement and beauty in physical and optical phenomena while helping them learn the theoretical concepts and conducting experiments that can test the validity of the concepts. Such motivation largely relies on realistic hands-on lab opportunities where…
