This study investigates the influence of inquiry-based laboratory activities on the understanding of heat concepts and the self-efficacy beliefs of pre-service primary teachers. Recognizing that both scientific literacy and teaching efficacy are critical for effective science education, this research aims to determine how inquiry-based laboratory…

Lab-on-a-chip devices are a critical and emerging chemical technology. New pedagogical tactics that effectively capture both analytical chemistry concepts along with the design elements unique to these devices are necessary for effective integration in the undergraduate chemistry curriculum. This article develops a design-based learning laboratory…

An inquiry-based learning approach was implemented into comprehensive organic chemistry experiments focusing on the formation process of N-phenylbenzamide from the reaction between N-benzylideneaniline and benzoyl peroxide in commercial dimethyl sulfoxide. Students conducted comparative experiments using alternative reagents or reaction conditions…

The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

We designed and evaluated a student laboratory workshop on plant-based vaccines against the SARS-CoV-2 virus. The workshop focused on hands-on laboratory techniques, including DNA extraction from rice seeds, where the recombinant protein was produced, detection of the transgene, and basic concepts on how vaccines work in the human body to offer…

Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…

Hands-on, inquiry-based laboratory activities are excellent opportunities to introduce first-year undergraduate students to the lab environment and to catalyze new interest in topics they may not yet know or be as enthusiastic about studying. We describe a multisession introductory laboratory activity that couples the research areas of medicinal…

Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

In this guided-inquiry lesson, students were tasked with determining the efficacy of an at-home drinking water filter at removing lead (Pb) from tap water using graphite furnace atomic absorption spectroscopy by determining the concentration of lead before and after filtration. The lesson was structured to allow students to choose and perform…

The integration of scientific modeling into science teaching is key to the development of students' understanding of complex scientific phenomena, such as genetics. With this in mind, we conducted an introductory hands-on module during an outreach gene technology laboratory on the structure of DNA. Our module examined the influence of two model…

NMR is a fundamental part of any undergraduate chemistry degree, and training students how to measure and interpret NMR spectra is essential for postgraduate research or chemistry-based careers. Traditionally, the undergraduate laboratory experience with NMR is restricted to sample submission for NMR analysis, which is typically conducted by a…

Scientific laboratories are among the most challenging course components to integrate into online instruction. Available technology restricts the design and nature of experiments, and it can be hard to replicate the collaborative lab environment where frequent and immediate instructor feedback is the norm. Here we report on technological and…

The content and design scheme for a readily adaptable, research-based laboratory course in chemical biology are presented. In this course, students interrogate protein structure and function using the site-specific incorporation of noncanonical amino acids by genetic code expansion. The relatively new field of genetic code expansion enables…

This high school-level, place-based, inquiry-driven laboratory module familiarises students with techniques used to analyse animal behaviour while facilitating the development of the observational skills highlighted by the Next Generation Science Standards (NGSS). Throughout the module, students observe, quantify, and discuss local invertebrate…
