We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

Faculty members in STEM report numerous motivators and barriers to adopting evidence-based instructional practices (EBIPs), yet the degree to which these factors are associated with EBIP adoption in postsecondary chemistry courses is unclear. The role of departmental climate around teaching in driving or hindering EBIP adoption is particularly…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

Minoritized communities, including Black and African American, Hispanic and Indigenous populations have remained historically underrepresented in STEM careers due to persistent challenges in the STEM pipeline. The STEM pipeline has struggled to retain minoritized students in their journeys to pursue STEM degrees and careers due to systemic racism,…

Students' self-efficacy, interest, and perceived recognition from others in a given field have been shown to be very important for the development of their identity in that field, which is a critical predictor of students' major and career decisions. Prior research suggests that students' self-efficacy and interest play an important role in their…

Through this qualitative phenomenological I studied the lived experiences of online science instructors who teach online introductory science. The problem addressed in this study was the high failure and attrition rates in online introductory science courses among undergraduate students. The purpose of this study was to explore the lived…

The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

Underrepresentation of some populations in STEM fields occurs because these students experience achievement gaps with performance lower on average than their overrepresented peers. Interventions to reduce achievement gaps and increase the retention of underrepresented students in STEM courses include approaches found both inside and outside of…

During COVID-19 lockdowns, online learning activities had to be developed for the Undergraduate and Masters by Coursework Bioinformatics students at RMIT University. Therefore, we designed an integrative, industry-based research assignment, which guided the students through a drug discovery project from target identification to lead optimization.…

As a result of the worldwide dissemination of COVID-19, educational institutions across the globe, particularly those that serve students in the field of science, have been mandated to close their doors. Consequently, educators and students have increasingly relied on educational technology to obtain a diverse array of resources. This research…

We calculate the frequency of matter-wave of electrons orbiting the hydrogen nucleus at the ground state. It is the same as the value of light frequency corresponding to the ground state from the Rydberg's formula. The result will stimulate students' interest to further understand the mechanisms of quantum theory.

Science in Latin America has a rich, complicated history, but it is often ignored both by traditional historians of science, as well as Latin American historians. Latin American science is characterized by liminality, "nepantlismo," an in-between-ness, a hybridization, a "mestizaje" of multiple indigenous, Creole, imperial…

Nowadays, inquiry-based learning is getting a lot of attention as an effective education method. Therefore, it has been researched and implemented in various countries. Inquiry-based learning has been used in various subjects such as biology, mathematics, social studies, and others. In order to encourage a smooth implementation of inquiry-based…

A flexible and modular peptide modeling set was designed using freely available software tools. The set consists of space-filling models of all 20 naturally occurring amino acid side chains and a modular kit for constructing peptides employing C-alpha carbons and amide bond groups. Connectors that allow free rotation about phi and psi angles on…

Analogies are useful tools instructors can use to help make challenging concepts less abstract by drawing connections to familiar contexts. In this paper we provide an overview of the various analogies published in the education literature that are situated in the context of enzyme kinetics, including narrative-based analogies (analogies intended…
