We developed a hands-on course in molecular biology for undergraduate underrepresented in medicine (URM) students. To incentivize student preparation for team-based learning (TBL) activities, we implemented a novel grading schema that requires a minimum individual readiness assurance test (iRAT) score to share the team group readiness assurance…

This study examined laboratory experiments and traditional lecturing as an introductory teaching method in physics. In this participatory action research study, a qualitative and quantitative method were used to examine the level of achievement and the levels of engagement of high school students in introductory physics. The qualitative data was…

Students in the Didactic Program in Dietetics (DPD) at the University of Maine were exposed to the cheese-making process, within a lab setting of two hours, utilizing an accelerated recipe for a Queso Fresco-style cheese. The purpose of this project was to provide students with a novel, hands-on learning experience, which covered concepts of…

In this article, a low-cost, simple, and rapid fabrication of paper-based analytical devices (PADs) using a wax screen-printing method is reported here. The acid-base reaction is implemented in the simple PADs to demonstrate to students the chemistry concept of a limiting reagent. When a fixed concentration of base reacts with a gradually…

This paper presents a set of laboratory classes to be taught as a part of a 1 year calculus-based physics class. It is composed of 7 modules designed to bring together experiments and computer simulations. Each module uses both simulations and experiments to address a phenomenon under study, and lasts for 3 weeks (21 weeks total for the whole…

Background: Engineering programs must equip students to solve open-ended workplace problems. However, the literature points to actual or potential difficulties faced by students in solving open-ended or complex problems. During Fall 2014, the authors' students experienced difficulties in solving open-ended bio-signals laboratory problems of…

This work describes an effective, low cost method to anodize small aluminum objects. The use of a PVC spacer between the anode and cathode significantly reduces the size of the electrochemical cell and electrolyte required for its operation. Students will explore the physical and chemical properties of aluminum and anodized aluminum. They will…

Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…

Service-learning (SL) is an active learning approach that connects the knowledge a student acquires in the classroom to an application that benefits the community. Increasingly popular in the chemistry curriculum, service-learning is reported to provide student benefits including improved cognitive goals; increased academic, interpersonal, and…

The ability to think critically and creatively are essential graduate attributes for science students yet many science graduates lack these skills and may struggle to gain employment. As undergraduate science educators, we are aiming to improve critical thinking, creativity and the promotion of deeper learning in our students. We have designed and…

In classroom science laboratories, unlike a real science laboratory, the teacher can guide students away from potential dead ends and toward data that are most likely to result in accurate conclusions. Sometimes, though, allowing students to pursue dead ends and to collect "bad" data can provide especially rich learning opportunities.…

This paper presents a method to design high-quality 3D equipment for virtual laboratories. A virtual control laboratory is designed on large-scale educational purpose with merits of saving expenses for universities and can provide more opportunities for students. The proposed laboratory with more than 30 virtual instruments aims at offering…

The correct labeling of seafood is important to protect nature and the rights of consumers. Given the certainty that the resources of the sea are not inexhaustible, only strict regulations and the implementation of sustainable fishing systems and reliable and traceable marketing systems can help ensure the long-term sustainability of fishery…

Near-peer teaching, in which students one or more years removed from a student within the same academic program, is utilized broadly in medical school curricula and increasingly in undergraduate anatomy and physiology courses. While the literature on near-peer teaching suggests that the practice is overwhelmingly positive, it is primarily from…

While orthoesters are often used by chemists as alkylating, acylating, and formylating agents, they are rarely encountered in introductory organic chemistry curricula. We describe a second-semester organic chemistry laboratory experiment in which students acetylate unknown amine hydrochloride salts with trimethyl orthoacetate (TMOA) in the absence…
