This January marked the 52nd anniversary of the Apollo 1 fire. On Jan. 27, 1967, the interior of NASA's AS-204 command module (CM), occupied by American astronauts Roger Chaffee, Virgil "Gus" Grissom, and Ed White, caught fire during a rehearsal of its scheduled Feb. 21 launch. By the time the ground crew was able to open the hatch, the…

Exposure to nature can improve mental health and cognitive abilities, while creating enhanced engagement with biological course material through interactions with organisms and ecosystems. Remote biology education was suddenly implemented during the COVID-19 pandemic at many universities, and such distance education continues to provide broadened…

While light microscopy (LM) and virtual microscopy (VM) are valuable pedagogical approaches in histology education, studies comparing their effectiveness have primarily emanated from North America. This research aimed to compare the performance, satisfaction, and perception of Chinese undergraduate dental students enrolled in a histology…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Over the past half century, computational chemistry has evolved from a niche field to a ubiquitous pillar of modern chemical research. Driven by the increased demand for computational chemistry in research settings, the undergraduate curriculum has evolved alongside to ensure that students are well-equipped for modern research. Toward this end,…

Teaching laboratories are a highly complex environment that require students to master the following: technical skills, application of theory, safe working conditions, and teamwork. Often, students have had very little prior experience to prepare them for this alien and pressured environment. Prelaboratory tasks are typically considered key to…

This experiment introduces undergraduate organic chemistry students to analysis and interpretation of Fourier transform infrared (FTIR) spectra through characterization of postconsumer plastics. Students use FTIR spectra to identify and differentiate the common recyclable polymer resins #1-6: polyethylene terephthalate (PETE), polyethylene (HDPE…

Undergraduate laboratory courses are essential to teaching core principles in STEM. This course, Quantitative Biological Methods, provides a unique approach to teaching molecular biology research techniques to students, in a laboratory that is delivered in a sequence that parallels standard biomedical research laboratory protocols. Students attend…

The Poisson distribution describes the probability of a certain number of events occurring in an interval of time when the occurrence of the individual events is independent of one another and the events occur with a fixed mean rate. Probably the best-known example of the Poisson distribution in the physics curriculum is the temporal distribution…

Students sometimes learn about a model of the "scientific method" that is linear and clear cut. While this approach may have pedagogical advantages, it does not reflect how science is often done in practice. The Experimental Modeling Framework (EMF) describes the complex and iterative process of experimentation in the domain of physics,…

Special Relativity introduces students to Modern Physics, whose importance in the high school is increasing. Nevertheless its teaching and learning is a critical issue. Different solutions have been developed to overcome the encountered difficulties. In this paper we describe the spacetime globe, a mechanical instrument that allows to experience…

The article introduces a low-cost Arduino sensor into the Young's modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass's frequency…

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…

Growth in the biomedical and biotechnology sectors requires a highly trained and highly skilled workforce to answer the next great scientific questions. Undergraduate laboratory courses incorporating hands-on training based in authentic research position soon-to-be graduates to learn in environments that mirror those of academic, industrial, and…

Nanotechnology has been recognized as an important driver of the future economy, and so nanoscience is increasingly being incorporated into the undergraduate chemistry curriculum. This experiment includes the chemical synthesis, optical and chemical testing, and microscopic imaging of gold nanoparticles. Since nanoparticles are too small to…
