Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

The integration of Virtual Laboratories (VLs) into blended learning environments in science education offers a multifaceted educational experience that bridges the gap between theoretical knowledge and practical application. This approach provides dynamic, interactive learning opportunities that can be customized to meet various educational needs…

The problem addressed through this study was the absence of a critical examination of laboratory exercises used with first-year nonbiology majors and the deployment of virtual laboratories in the biology department at the project site university without critical analyses associated with the efficacy of virtual labs. Grounded in Mayer's cognitive…

A virtual microscope resource was created when face-to-face labs were halted due to the COVID-19 pandemic in March 2020 to replicate the learning goals of an introductory petrology course on microscopy. This virtual microscope resource utilized images and videos of thin sections, as well as 3D rock models to allow students to complete labs online.…

Basic Human Anatomy at Indiana University is a large undergraduate anatomy class with nearly five hundred students in twelve lab sections. In the fall of 2018, we added the Virtual Human Dissector software on an interactive Sectra table to our lab to help students fill the gap between idealized anatomical models and fully prosected cadavers. We…

Virtual laboratories are transformative tools in science education, yet comprehensive reviews of their prospects are limited. This study addresses this gap through a bibliometric analysis of 218 articles published between 2013 and 2023. Key findings included: (1) research has evolved from initial exploration to rapid expansion; (2) virtual labs…

Fluency in both the construction and interpretation of molecular structures is a critical learning objective in the second-year organic chemistry curriculum. With the introduction of PerkinElmer's ChemDraw structure drawing tool into undergraduate laboratory courses, students are challenged to develop fundamental molecular drawing skills using…

Campus shutdowns during the SARS-CoV-2 pandemic posed unique challenges to faculty and students engaged in laboratory courses. Formerly hands-on experiments had to be quickly pivoted to emergency remote learning. While some resources existed prior to this period, many currently available online modules and/or simulations focus on a single…

A chemical engineering student's knowledge of theory, experimental design, and real-world processes is tested and enforced in the Unit Operations laboratory courses. However, instructors are facing challenges of delivering high-quality, hands-on laboratory content with limited resources and increasingly large class sizes. Limited in-lab time is…

The analysis of spontaneous tail coiling (STC) in zebrafish embryos is a functional parameter that allows the study of motor development. It has recently gained relevance as a biomarker to assess the neurotoxicity of environmental substances. Its practicability in the laboratory makes it an excellent pedagogical tool for promoting students'…

Integrating virtual laboratories (VLs) with science education promotes inquiry-based learning by providing an interactive, dynamic environment in which students actively engage with scientific concepts. While previous research highlights the effectiveness of VLs as tools in the IBL process, few studies have embedded the entire inquiry process…

A bioinformatics laboratory experiment was designed to help undergraduate students learn RNA structure and function in biochemistry courses. In this laboratory experiment, students used 5S rRNAs as material to predict secondary structure and visualize three-dimensional (3D) structure. Students first downloaded molecular information from the 5S…

Virtual Chemistry Laboratories (VCLs) are used as an alternative to the physical laboratories, where users can enhance their performance for hands-on chemistry experiments. However, cognitive load and other issues make the VCLs impractical. The issue of cognitive load arises due to the complexity of the environment by displaying a number of…
