Evidence suggests that students exposed to authentic undergraduate research activities are more successful than those who are not. Not all students in an undergraduate program get an opportunity for mentored research, which is still the popular way to expose them to authentic research. However, involvement in undergraduate research can be…

Cell biology research methods and techniques is one of the training courses for graduate students before enter the laboratory in many universities. However, due to the limited time of experimental teaching while the teaching contents are increasing, choosing suitable teaching content has always been a challenge faced by experimental teaching.…

Ensuring that botany and plant sciences are being included in undergraduate life science curricula is necessary for developing a future global sustainability workforce. To gain a baseline understanding, we surveyed life science educators in the U.S. about current botanical education. We further evaluated these data to determine connections to the…

Academic misconduct, including plagiarism, collusion and contract cheating, is a growing concern in Higher Education, particularly with the rise of online assessments. This study examines staff and student perceptions of outsourcing behaviours at a research-intensive UK university, exploring their prevalence, acceptability and influencing factors.…

This study explores how public communication was meaningfully integrated into a third-year undergraduate science course at a Canadian university through a podcasting assignment. In this course, students collaboratively produced science audio podcasts for radio broadcast, engaging in authentic, public-facing communication. Drawing on a qualitative,…

The directional feature of Earth's geomagnetic field has been contributing to the technological development and prosperity of humankind since the invention of the magnetic compass navigation centuries ago. Today, for instance, magnetoresistance sensors are commonly used in nanosatellites and unmanned aerial vehicles for high accuracy geomagnetic…

Ion-selective electrodes are among the oldest and most important potentiometric sensing methods. In this experiment, students assemble their own reusable ion-selective electrode from glass tubes with an attached PTFE membrane, [(CH[subscript 3]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript…

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…

Nuclear magnetic resonance (NMR) spectroscopy is commonly introduced to students in the classroom, but its hands-on use in undergraduate laboratories is far less common. The significant costs to purchase and maintain a traditional high-field NMR spectrometer means that many institutions cannot offer this service to their students. Benchtop NMR…

Raman spectroscopy has become a popular analytical tool because of its ability to probe nondestructively and provide fingerprint information about materials. The advancements in the field of Raman spectroscopy and the expanding scope of applications warrant the introduction of the topic in the formal education curriculum. The introduction of Raman…

With the enormous reliance on plastics in the world today, bisphenol A, an additive used in the synthesis of many plastics, such as polycarbonate, has been found almost everywhere in our environment including in soil, in natural waters, and inside organisms including humans. A multidisciplinary experiment is presented that involves using flatworms…

One particular challenge in chemistry learning is developing students' atomic level understanding of chemical processes. It is necessary to help students learn how to critique atomic models rather than accept them as ''truth.'' In this study, we used a resources-based framework to examine how students made sense of macroscopic level information to…

Using polymerizable cholesteric liquid crystal (CLC) paints, we prepare circularly polarized freestanding films that enable students to acquire a basic understanding of circular polarization and molecular chirality. The polymerized helical structures of CLC films can exhibit brilliant structural colors by selective reflection of visible light…

The basic SIR (susceptible-infectious-removed) model of epidemiology is presented in chemical kinetic terms with a simple two-reaction mechanism. The conditions for the development of epidemics, the course of a simple closed epidemic, and the bases of several mitigation strategies are described in terms of the underlying first- and second-order…

X-rays are such an important and familiar part of the electromagnetic spectrum, but is there a way to safely bring x-rays into your lecture? The demo team at the University of California at Berkeley seems to have managed this. They have an x-ray safe box that they use to produce a live x-ray image on a fluorescent screen. In this article, we…
