The contamination of wastewater with metals and the use of biotechnologies to remove them is commonly discussed in theoretical biology, microbiology and biotechnology classes aimed at undergraduate students. This work introduces an easy, economical and safe practical laboratory class related to this topic. The practice consists in performing batch…

This study is a comparison of ground-based versus online student performance using a combination of common final examination scores and associated demographic data in a biological science college course taught by a single instructor. Multivariate and standard statistical analyses are used to examine data from five semesters of ground and online…

The laboratory experiment regarding esterification of ethylene glycol with acetic acid to ethylene glycol diacetate using resin catalysts in a continuous flow was designed to carry out the reaction in a flow through an inquiry-guided approach. Incorporating the burgeoning field of continuous flow chemistry into the educational infrastructure, the…

As green chemistry and engineering are being integrated into chemical processes in academia and industry, it becomes equally important to equip students with the relevant tools in the fields of sustainable chemistry and processes. In this context, continuous flow technology has been identified as one of the promising strategies. Herein, we…

In a chemistry course for students not majoring in science, there is more to learn than some memorized facts: the student can find, in most non-major chemistry texts, the definition of atomic number, something about chemical bonding, and names of some classes of chemical compounds. Where facts come from and how accurately they are known are often…

Recent trends toward engaging undergraduate biology students in scientific investigations have shifted focus toward helping students understand and use scientific evidence. Instructors must promote students' evidentiary reasoning as they generate, use, and evaluate scientific evidence during the investigations. However, explicit guidance is needed…

The gap between the number of available STEM workers and employers' needs in the workforce is projected to be about two million by 2025. One way to reduce the magnitude of this gap is to increase the number of entry-level STEM workers joining the workforce, however the attrition rate for college STEM majors is about 33%. Research has indicated…

This study investigates the efficacy of incorporating neuropedagogical elements into virtual simulators for advanced chemistry education in universities. Utilizing a mixed-method approach, it uses questionnaires completed by 50 organic chemistry students. These questionnaires included both general and Likert scale questions, focusing on students'…

Movies have long been used for teaching in undergraduate science courses. However, embedding movie references (EMR) in science videos is a new trend. This study explored how EMR in YouTube science videos might affect the nature of comments and the process of learning science. Using constructivist grounded theory, we compared comments on two…

Scientific literacy is an increasingly important skill for today and tomorrow's citizens. Encapsulated in the definition of being scientifically literate, one must be knowledgeable about science and technology in context and be able to interpret and communicate the information well. Introductory science courses, like general chemistry, are key…

Science is often portrayed as a meritocratic endeavor, but university biology programs exhibit high rates of student attrition, particularly among students of Color, despite similar interest and aptitude for science, technology, engineering, and mathematics (STEM) as White students. Culturally relevant pedagogy is associated with student…

The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

The COVID-19 pandemic was highly disruptive and Institutions of Higher Education struggled to effectively educate undergraduate Science, Technology, Engineering, and Mathematics (STEM) students, who were facing unique challenges in their modified learning environments. While some research has focused on educational challenges encountered in…

Authentication of the Vinland map manuscript, supposedly from the 15th century, was used as a case study in an undergraduate upper-level instrumental-analysis class. The case provides a review of spectroscopic techniques and data analysis from several nondestructive techniques. Assessment of the case shows it to be particularly beneficial for…

A large-enrollment, introductory physics laboratory course at the University of Colorado Boulder has undergone a recent transformation to help students' develop lab skills and better align students' views and beliefs about experimental physics with those of expert experimental physicists through engagement with authentic scientific practices. We…
