Laboratory experiments provide students a tangible means of understanding dry, abstract concepts. A simple and engaging introductory wet chemistry laboratory has been developed relating quantum mechanics to color, which has been implemented for a class of about 600 students per academic year for over three years at Brown University. Color is an…

"Cannabis sativa" is a species of plant with a rich, yet controversial history. Although the utility of cannabis has been documented for thousands of years; during the last century, research has led to a more advanced understanding of its mechanism of action and therapeutic potential. Accordingly, there has been an explosion of interest…

Physics lab courses are integral parts of an undergraduate physics education, and offer a variety of opportunities for learning. Many of these opportunities center around a common learning goal in introductory physics lab courses: measurement uncertainty. Accordingly, when the stand-alone introductory lab course at the University of Colorado…

Herein, we present an experience-based learning approach that uses the COVID-19 pandemics knowledge about virus spread and epidemics to establish an analogy between a simple epidemics model--the SIR model (susceptible--infected--removed), and a second-order autocatalytic reaction with subsequent catalyst deactivation. Our approach provides a…

On March 19, 2020, Argentina's government decided to close academic institutions for an indefinite time in an attempt to contain the spread of the COVID-19 pandemic. Since the University established that, when the quarantine ends, 5 weeks will be reserved for face-to-face activities that could not be carried out virtually (laboratory lessons and…

The need to develop clean-energy storage systems, harvesting technologies, and new functional materials are but a few of the many contemporary challenges in the domain of science today. To address these challenges, problem solving has become a key skill of the 21st century. It is generally documented, however, that experts and students differ in…

Poster presentations to communicate scientific knowledge/understanding are a commonly used assessment tool. It can be a challenge for students (and staff!) to deliver clear information with minimal text on the poster. We have found that this format did not encourage imaginative project topics or posters. To enhance communication skills,…

Ensuring undergraduate students become proficient in relating protein structure to biological function has important implications. With current two-dimensional (2D) methods of teaching, students frequently develop misconceptions, including that proteins contain a lot of empty space, that bond angles for different amino acids can rotate equally,…

The theory of evolution is the backbone of the biological sciences. Arguably, this is the reason why evolution education is an extensively investigated issue in several countries around the world. Little is known, however, about the views of university students in Colombia. Here, we report on 7 years of data generated by a three-question anonymous…

The comprehension of the reactivity of the elements is an important goal to be achieved in undergraduate courses in inorganic chemistry. Therefore, at Universidade Federal de São Carlos (UFSCar), the B.Sc. in chemistry has a laboratory course dedicated to the chemistry of the elements. However, we have noticed a decrease in students' interest in…

The aim of this study was to investigate whether and how engaging with a computer-supported collaborative knowledge-building environment helps students to develop a more sophisticated approach to scientific inquiry. A total of 52 undergraduate students took a course entitled "Introduction to Natural Sciences" that was based on…

Novel assessment tools are more often used in class especially after the Bologna Process (Pereira, D.; Flores, M. A.; Niklasson, I. Assess. "Eval. Higher Educ." 2016, 41, (7), 1008-1032, DOI: 10.1080/02602938.2015.1055233) in Europe. "Kahoot" has emerged as an attractive and interactive gaming platform, and considerable…

English language learners are increasingly entering classrooms using student-centered instruction that places a greater emphasis on spoken language. While active learning is beneficial for a range of student outcomes, these practices force language learners to carry a heavy cognitive load in a complex and challenging environment. This experiment…

Authenticity is a term that has become ubiquitous within the field of science education, particularly when it relates to the practices of science. These practices are a key feature of science education reform documents in the US. However, a common definition of just what makes for the authentic doing of science is hard to come by and certainly…

Online formative assessment is still challenging although it is getting an increased attention as a significant tool for diagnosing and analysing students' motivation and achievement in various education domains. This research examines the effects of an online formative assessment tool (OFAT) about science motivation and achievement in second-year…
