Active learning environments are ideal settings to help students develop process skills such as teamwork, critical thinking, and problem solving. However, implementing active learning pedagogies where students have the opportunity to develop these skills can be challenging in large enrollment courses. With the assistance of undergraduate teaching…

The demand for sustainable synthetic methods has motivated the development of a myriad of strategies for substrate oxidation chemistry that reflect the goals of green chemistry. Here we present a two-part laboratory module that provides undergraduate chemistry students hands-on experience with the concepts of sustainable chemistry in the context…

A virtual reality (VR) session was introduced to an advanced inorganic chemistry class, a class available to junior and senior undergraduate students at the University of California, Los Angeles. The VR session helped the students to learn complicated aspects of metal coordination chemistry and molecular orbitals via an immersive three-dimensional…

A classic undergraduate introductory experiment is to measure the diffraction and interference pattern from single and double slits to determine slit width and separation. Studies show that Course-based Undergraduate Research Experiences (CUREs) can make science more inclusive when offered at the undergraduate level. Additionally, CUREs help…

Communicating the flow of genetic information (DNA ? RNA ? protein) is not only a basis of biochemical education, but also is the essential foundation for understanding the complexity of biological processes. The described laboratory exercise demonstrates that the information encoded into different DNA sequences can be transformed into various…

A laboratory exercise for the synthesis of a sulfonated styrene-"co"-maleic anhydride polymer and its application as a stain blocker on nylon-6,10, is described. The effectiveness of the sulfonated polymer to prevent the conjugate base of an acid dye from staining the polyamide is demonstrated. This experiment is designed for…

In this article, we use a simple lattice model to illustrate the concepts of entropy, free energy, and thermodynamic equilibrium from a microscopic perspective. These physical concepts are based on elementary knowledge of discrete probability distribution and weighted average. Calculations about this model involve basic algebra and counting, which…

This article describes a workshop to develop students' understanding of how to investigate a cross-disciplinary question that bridges science and history. The question 'Why did the "Titanic" sink?' is interpreted scientifically and then historically to help students to better appreciate the strengths and limitations of each discipline's…

Defining what is meant by 'life' seems, on the face of it, straightforward. But, as this article explores, once you delve below the surface you find that providing a definition that everyone agrees upon is nearly impossible. By first considering how biologists and philosophers of science debate the issue of defining life, the article then goes…

Principles of conservation are essential to the physical understanding of the universe. When thinking about its teaching, especially aimed at basic education, experimental activities can be great allies for its understanding. In this article, we present a demonstrative model using a fidget spinner arranged in a structure constructed using 3D…

To study the absorption of ultrasound in plexiglas we propose to use gadgets that are available to each student: an ultrasound humidifier, a liquid crystal display of a pad, a polaroid analyzer, a digital camera, a multimeter with thermocouple, and a stopwatch. These devices allow us to visualize a region in plexiglas where ultrasound is absorbed…

Although 20 states have adopted Next Generation Science Standards (NGSS), 24 other states have developed their own K-12 science standards based on the same National Research Council (NRC) Framework. Understanding what influences content standards developers, realizing the supports and impediments to implementation they foresee, and knowing their…

Spatial abilities have been correlated to anatomy knowledge assessment and spatial training has been found to improve spatial abilities in previous systematic reviews. The objective of this systematic review was to evaluate spatial abilities training in anatomy education. A literature search was done from inception to 3 August 2017 in Scopus® and…

Practical work is widely seen as an important element of the science curriculum. However, there is a long-standing debate about the educational aims of practical work and about why it is important. Aims suggested include the contributions that practical work can make to understanding, to the acquisition of professional and personal skills, and to…

Although teaching laboratories offer students the opportunity to act and think like chemists, in many cases students simply follow written procedures to generate predetermined outcomes. In recent years, there has been a movement toward inquiry-, problem-, and discovery-based learning. In a similar vein, the first-semester introductory organic…
