Brewing science is an interdisciplinary course taught at many universities in both lecture- and lab-based modalities. The laboratory component of this class typically focuses on the brewing process from malted barley to beer. However, this ignores the malting process--an essential step in making beer, although one typically performed by maltsters…

Dilute guarana´ ("Paullinia cupana") powder aqueous extract is a soft drink that contains three structurally related methylxanthines (MXs), caffeine (CF), theobromine (TB), and theophylline (TP); CF is present in a large excess. Literature data show that values of [lambda][subscript max] and [epsilon][subscript max] of these three MXs…

Despite extensive conceptualization of ions as hard spheres in most textbooks, solid-state structures are more accurately modeled as overlapping soft spheres that better reflect the size of the ions. The corresponding soft-sphere ionic radii of alkali and halide ions can be empirically established from the partial molar volume of the ions in…

The inhibition of porcine pancreatic lipase by the drug orlistat was studied through a series of activities that combine experimental and computational procedures. The enzymatic activity of the lipase was determined by measuring enzyme kinetics and calculating parameters such as K[subscript m] and V[subscript max] from experimental data. Assays of…

Additive manufacturing (AM) is projected to require 60,000 jobs in the UK by 2025, but there are a series of barriers to the industrial application. One of the most problematic is non-comprehensive knowledge in design for AM (DfAM). This study aims to test the effect of two undergraduate DfAM teaching approaches. A visual and audial approach…

Immersive learning technologies such as virtual reality (VR), augmented reality (AR) and educational digital games offer many benefits to teaching and learning. With their potential to immerse learners in realistic environments and facilitate higher-order cognitive learning, these technologies could be used to complement current classroom…

Concepts relating to enzymes and energy are central to understanding chemical and biological processes at the molecular level. Student learning of these crosscutting concepts can be challenging, so it is important to identify misconceptions and remediate them early, especially in introductory classes. Here we describe an activity in which…

The purpose of this study, grounded in the Achievement Goal Perspective Theory (AGPT) and a Caring framework, was to effectively adapt previously validated measures of caring, task-involving (CTI), and ego-involving (EI) climates for college exercise classes to the college biology laboratory setting. The items' measurement quality was assessed…

Project-based learning (PBL) research is shown to improve students' higher-order thinking skills. In this article, we describe an adaptation of the PBL model that is suitable for colleges with limited science, technology, engineering, and mathematics research capabilities. Our objective was to design a meaningful research project requiring minimal…

While several studies have investigated gender inequities in the social learning environment of biology lecture courses, that same phenomenon remains largely unexplored in biology laboratory contexts. We conducted a mixed methods study to understand the influence of gender on student perceptions of their peers' research aptitude in introductory…

We developed a remote lab experience where freshmen grew and analyzed the activity of sourdough starters as a means of engaging with chemical engineering concepts. This six-week hands-on activity was targeted due to its low-cost, non-hazardous materials, and ability to be conducted safely in a non-laboratory setting. By designing the lab to be…

Indirect and direct assessment methods have a long standing history in college learning centers. Being more resource-intensive and time-consuming, direct assessment methods are often underrepresented in the literature and in practice. This paper presents a case study of how a pretest-posttest assessment initiative was designed to measure student…

Medical laboratories across the United States have been experiencing a workforce shortage for the past several decades. While the causes of this shortage are numerous, one of the contributing factors is high turnover and attrition rates due to low workplace satisfaction. Research has shown that higher levels of self-efficacy lead to increased job…

Lab activities are a vital part of physics courses, providing students with hands-on experiences of classroom topics. At the same time, building self-efficacy is vital to student learning and retention; however, females traditionally have lower self-efficacy in STEM fields. This research explores the role of gender and the changes in interest in…

This Doctor of Arts dissertation addresses the use of drawing as a tool to facilitate life science education and research. The literature review addresses frameworks of drawing-to-learn and Professional Vision which guided the design and implementation of the research and education experiences. A result of this dissertation work is a manuscript…
