An undergraduate practical exercise has been designed to provide hands-on, instrument-based experience of advanced characterization techniques. A research experience approach is taken, centered around the concept of solid-state polymorphism, which requires a detailed knowledge of molecular and crystal structure to be gained by advanced analytical…

The author discusses an Introduction to Biology course they created. The course was designed by following the recommendations from the Vision and Change in Undergraduate Biology Education: A Call to Action report, which stresses the need for engaging students through hands-on and student-centered activities. In the course, students perform…

Saccharin (1,2-benzisothiazole-3-one 1,1-dioxide) is an artificial sweetener used in the food industry. It is a cheap and easily available organic compound that may be used in organic chemistry laboratory classes for the synthesis of related heterocyclic compounds and as a derivatizing agent. In this work, saccharin is used as a starting material…

This article presents a large-scale evaluation study of over 3000 9-14-year-old students who participated in an engineering workshop during their school fieldtrips. Student perceptions right before and after, as well as two weeks after the workshop were captured and examined. Before the workshop, younger students and boys, generally exhibited…

This study's goal was to understand the extent to which providing access to media resources focused on critical science and engineering concepts can help children living in low-income households learn. The resources examined were from the PBS KIDS multi-platform property "The Cat in the Hat Knows a Lot About That!" Researchers found that…

The National Institutes of Health and the National Science Foundation have made a compelling call to action not only to strengthen the pipeline of available STEM-trained talent, but in addition to foster students who are members of populations currently under-represented in science. furthermore, the scientific community must not only increase the…

The concept of wave-particle duality in quantum theory is difficult to grasp because it attributes particle-like properties to classical waves and wave-like properties to classical particles. There seems to be an inconsistency involved with the notion that particle-like or wave-like attributes depend on how you look at an entity. The concept comes…

Students who are blind or visually impaired (BVI), like all students, need to conduct scientific investigations that involve measurements and reading experimental procedures. Best instructional practices for BVI students include touch and hearing experiences. Related strategies and tools include electronic textbooks, assistive technologies such as…

Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and…

This research study describes the correlations between student performance and examination format in a higher education teaching and research institution. The researchers employed a quantitative, correlational methodology utilizing linear regression analysis. The data was obtained from undergraduate student test scores over a three-year time span.…

We describe a 3-hour session that provides students with the opportunity to review basic lab concepts and important techniques using real life scenarios. We began with two separate student-engaged discussions to remind/reinforce some basic concepts in physiology and review calculations with respect to chemical compounds. This was followed by…

Children act as emergent scientists through active involvement with their environment and adults. Science forms an important component of early childhood education curriculum in Mauritius. Since 2015, The Rajiv Gandhi Science Centre (RGSC), has initiated a new project: empowering educators to teach science in pre-primary schools. One-day workshop…

This column provides ideas and techniques to enhance your science teaching. This month's issue discusses using the 5E learning cycle to create coherent storylines. The 5E learning cycle provides an important framework to help teachers organize activities. To realize the full potential of the 5E framework for student learning, lessons must also…

A synthetic procedure is outlined where upper-level undergraduate organic chemistry students perform a two-week, semimicroscale "aza"-Baylis-Hillman reaction to generate an allylic sulfonamide product. Students evaluate several green chemistry reaction metrics of industrial importance (process mass intensity (PMI), E factor, and reaction…

Marble tracks are a very popular toy and big ones can be found in science centres in many countries. If children want to make a marble track themselves it is quite a job. It takes a long time, they can take up a lot of space and most structures are quite fragile, as the materials used can very quickly prove unfit for the task and do not last very…
