FRET (Fo¨rster resonance energy transfer) involves the transfer of energy from an excited donor fluorophore to an acceptor molecule in a manner that is dependent on the distance between the two. A biochemistry laboratory experiment is described that teaches students how to use FRET to evaluate distance changes in biological molecules. Students…

A green organic-inorganic laboratory experiment has been developed in which students prepare a self-assembling iron cage in D[subscript 2]O at room temperature. The tetrahedral cage captures a small, neutral molecule such as cyclohexane or tetrahydrofuran. [Superscript 1]H NMR analysis distinguishes captured and free guests through diagnostic…

A laboratory exercise was devised that allows students to rapidly and fairly accurately determine the iodine value of oleic acid. This method utilizes the addition of elemental bromine to the unsaturated bonds in oleic acid, due to bromine's relatively fast reaction rate compared to that of the traditional Wijs solution method. This method also…

The synthesis of alkenes using the Wittig reaction is a traditional part of many undergraduate organic chemistry teaching laboratory curricula. The aqueous medium version of the Wittig reaction presented is a reliable adaptation of this alkene formation reaction as a very safe alternative in the introductory organic chemistry laboratory. The…

We present a novel guided inquiry second semester organic chemistry laboratory rearrangement experiment. Students performed the Favorskii Rearrangement to obtain methyl cyclopentanecarboxylate in good yields. The students learned about the individual steps of the Favorskii mechanism and were required to propose a complete reaction mechanism and…

With the advancement in technology over the past decades, networks have become increasingly large and complex. In the meantime, cyberattacks have become highly sophisticated making them difficult to detect. These changes make securing a network more challenging than ever before. Hence, it is critical to prepare a comprehensive guide of network…

Three-dimensional virtual technology (3DVT) educational tools and peer-tutoring have proven to be effective teaching strategies in improving student learning outcomes. The purpose of this study was threefold: (1) compare the anatomy academic performance between underrepresented minority (URM) and non-minority (non-URM) students, (2) compare the…

Faculty at all types of colleges and universities struggle with how smartphone use may enhance or diminish their pedagogy, in part because evidence-based data is lacking for most types of classrooms. Thus, we conducted a thorough investigation in an introductory biology lab course to determine how smartphones affected myriad aspects of student…

This study focused on exploring and evaluating students' views of the Nature of Science in the context of undergraduate chemistry laboratory. Thirty-six undergraduate students doing a laboratory course in upper division physical chemistry were assessed using an open-ended instrument and assessment criteria that categorise them in three levels of…

Microplastic contamination of the environment is a major concern but detecting such contamination presents a challenge, particularly for particles <0.1 mm in size. Community scientists and students who participated in a plankton monitoring program and routinely examined samples of seawater using brightfield microscopy, often found fragments and…

Providing effective feedback is a skill preservice teachers develop through practice. According to Hattie (2012), feedback is essential in the learning process, is prevalent in effective teaching, and its purpose is to help students determine current level of performance, so adjustments can be made to enhance performance to desired level. This…

Traditional oral examination (TOE) is criticized for the shortage of objectivity, standardization, and reliability. These perceived limitations can be mitigated by the introduction of structured oral examination (SOE). There is little evidence of the implementation of SOE in physiology laboratory courses. The purpose of this study was to…

This study was conducted in order to better understand how, if at all, language centers (LCs) are relevant in current technological and methodological contexts of second language education. Five language centers housed by four different institutions of higher education in the western United States were examined. Two representatives from each of…

This paper discusses the experience of online studio activities for a second year project project-oriented design-based learning (PODBL) unit. The experience of delivering campus-based studio activities through an online platform, to a design a small power system, is shared due to COVID-19 restrictions. The student experience is benchmarked with…

Given student familiarity with electronic cigarettes (e-cigs), this lab uses a student-built smoke collection apparatus to collect e-cig vapors to teach students about gas chromatography-mass spectrometry (GC-MS). Students in a second semester, introductory organic chemistry course spent 1 week collecting e-cig vapors and 1 week qualitatively…
