Course-based undergraduate research experiences (CUREs) integrate authentic research into undergraduate chemistry laboratories, introducing students to research while simultaneously reinforcing fundamental concepts. Despite their ubiquitous nature in bioanalytical research, few CUREs have been published applying the fundamental techniques of…

Take-home examinations were utilized during the COVID-19 pandemic for upper-level analytical chemistry lecture courses. The questions were often scenarios which required the students to determine the best type of instrument to use and how to go about the experiment. Answers submitted were well thought out and detailed, showing that the students…

The manuscripts in this dissertation enhance the research on the psychology of the undergraduate student experience in laboratory courses, those that typify collaborative practical work. For science and engineering fields in higher education, persistence of students who identify as female and/or as a member of an underrepresented ethnic minority…

Laboratory experimentation providing students with hands-on experiences can greatly enhance the teaching and learning of physics. However, traditional hands-on laboratories are very expensive, limiting the possibilities for practical activities. In addition, limited time for laboratory practices prevents teachers and students from conducting…

We redesigned our undergraduate laboratories to create a structured sequence that continuously improves the learning experience of students. We utilized a PBL and PjBL approach in which students are progressively introduced to ill-structured open-ended problems, the development of projects, and the creation of research products. We dynamically…

This study examines the impact of constructivist physics lessons and laboratory activities on middle and high school students' academic success. Utilizing the constructivist learning model, which emphasizes active student engagement, the research was conducted at Hyperion Theoretical High School in Chi?inau, Moldova, involving 195 students across…

The importance of utilizing spectroscopic techniques for unraveling structural and compositional changes in nonreacting and reacting systems is unquestionable. Nowadays, efforts are directed towards the introduction of relevant spectroscopic techniques to undergraduate students in order to prepare them for future careers in industry and academia,…

Thermodynamic characterization of micelle formation from an ionic surfactant in aqueous solutions is a classic experiment in physical chemistry. The critical micelle concentration (CMC) and the degree of micelle ionization ([alpha)] can be directly obtained by conductimetry, then thermodynamic parameters ([delta]G[subscript m][superscript o],…

The Physics Laboratory of the Hellenic Open University has constructed a small scale and low cost air shower detector suitable for operation inside the classroom or school laboratory ([mu]Cosmics detector). In this work we present some of the educational activities foreseen with the [mu]Cosmics air shower detector, as well as the assessment of a…

The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…

Even though small talk has been investigated in a variety of business contexts and service encounters, it is understudied in instructional settings. This paper explores the occurrence of small talk in a university chemistry lab between a Chinese international teaching assistant (ITA) and American students. Drawing on naturally occurring…

Keto-enol tautomerism is a special example of structural isomerism. In this experiment, 6-chlorofulvene is predominantly yielded during the chlorination reaction of 6'-hydroxyfulvene with POCl[subscript 3] in the presence of DMF. The high regioselectivity of this reaction is dominated by intramolecular hydrogen-bonding and steric hindrance,…

The COVID-19 pandemic has resulted in a need for social distancing measures in public spaces and will have an important impact on university level teaching going forward. Remote methods to complete laboratory related activities are a potential means of students achieving practical credit while still isolating or social distancing. We outline the…

Since the sudden emergence of COVID-19 global pandemic, all educational institutions have looked to move resources and delivery online. Some institutions had already embraced delivering instruction in this way; however, broader adaptation to this teaching style is new to many educators. While the teaching of theoretical concepts is more easily…

The rapid transition in teaching format due to COVID-19 gives rise to many challenges, especially for research and lab activities since they may require a different approach with more constrained resources compared with lecture-based courses, in which various virtual communication platforms have now been employed. As essential parts for student's…
