Virtually all modern chemical instrumentation is controlled by computers. While software packages are continually becoming easier to use, allowing for more researchers to utilize more complex instruments, conveying some level of understanding as to how computers and instruments communicate is still an important part of the undergraduate…

A laboratory experiment is described for beginning, nonmajor chemistry students, which allows students to examine the phenomena of fluorescence and chemiluminescence, as well as gain experience in basic organic synthesis. Students synthesize fluorescein and bis(2,4,6-trichlorophenyl) oxalate (TCPO) to explore fluorescence and chemiluminescence by…

A series of Microsoft Excel spreadsheets were developed to simulate the process of separation optimization under isocratic and simple gradient conditions. The optimization procedure is performed in a stepwise fashion using simple macros for an automatic application of this approach. The proposed optimization approach involves modeling of the peak…

This letter comments on the paper "Analysis of Citric Acid in Beverages: Use of an Indicator Displacement Assay" ["J. Chem. Educ." 2010, 87 (8), 832-835 (EJ918557)]. Discrepancies in figures and host:indicator complex behavior are discussed and an alternative experimental protocol presented.

An organic chemistry experiment is described that is based on recent research to elucidate a novel cation-pi interaction between tetraalkammonium cations and propargyl hydrazines. This nonbonded interaction is a key component of the mechanism of ammonium-catalyzed intramolecular cycloaddition of nitrogen to the terminal carbon of a C-C triple bond…

A straightforward synthesis of 2-phenylimidazo[1,2-a]pyridine is described. The reaction is designed to demonstrate to students the preparation of a bridged N-heterocycle, in which the heteroatom occupies a bridgehead position. The product is obtained in moderate to high yield and is highly crystalline. The compound can be purified either by…

The Research PackTrack (RP) Program provides authentic research experiences to biology undergraduates in a modified studio environment. In semester 1, students are introduced to the process of scientific inquiry and discourse in a student-centered active learning environment with upside-down pedagogies. In semester 2, students work in a dedicated…

Studio-style course delivery involves the integration of laboratory activities with lecture elements of the course, with the goal of increasing student learning and satisfaction through directly linking laboratory and lecture concepts while focusing on active learning. In order to evaluate the effectiveness of studio delivery of an introductory…

Apart from the evident tragedy that the COVID-19 outbreak has meant regarding both personal and economic costs, the normal functioning of the academic year has been drastically altered at all educational levels. Regarding Spain, the state of alert implemented by the government from mid-March to June has affected traditional face-to-face sessions…

Social communication deficits associated with Autism Spectrum Disorder are often exacerbated during adolescence. Group based approaches are effective intervention techniques for facilitating improved social communication skills in people with ASD; however, science, technology, engineering, and math activities, while highly preferred areas of…

Studying quantum physics in upper secondary school is now a standard practice (Stadermann et al., 2019). But given the context of science education, with low recruitment numbers in higher education and poor attitudes towards science, it remains a question whether students find the learning of quantum physics relevant. In this study, we explore how…

This study examines the interest, motivation, and behavioral engagement of college students in an introductory course relative to three instructional formats used in the course: hands-on, problem-based laboratory stations; problem-based written case studies; and video lectures. Groups of five to seven students were assigned learning activities as…

This research presents the investigation of physics students' and physics faculty members' professional development and a design methodology via which we could best support them in their professional development. In particular, the first part of this dissertation will focus on undergraduate upper-division physics students' conceptual learning and…

As effective methods to foster students' understanding of scientific models in science education are needed, increased reflection on thinking about models is regarded as a relevant competence associated with scientific literacy. Our study focuses on the influence of model-based approaches (modeling vs. model viewing) in an out-of-school laboratory…

In education, the use of information, computers, and the Internet as a form of blended technology has been receiving increased attention and consideration. Additionally, increasing attention is being paid toward a scaffolding mechanism that can be integrated into science classrooms in order to solve technological challenges. This work describes a…
