Direct linkVarberg, Thomas D.; Pearlman, Bradley W.; Wyse, Ian A.; Gleason, Samuel P.; Kellett, Dalir H. P.; Moffett, Kenneth L. – Journal of Chemical Education, 2017
In this paper, we describe an experiment for the undergraduate physical chemistry laboratory in which students determine the speed of sound in the gases He, N[subscript 2], CO[subscript 2], and CF[subscript 3]CH[subscript 2]F. The experimental apparatus consists of a closed acrylic tube containing the gas under study. White audio noise is injected…

Knutson, Cassandra M.; Schneiderman, Deborah K.; Yu, Ming; Javner, Cassidy H.; Distefano, Mark D.; Wissinger, Jane E. – Journal of Chemical Education, 2017
With new K-12 national science standards emerging, there is an increased need for experiments that integrate engineering into the context of society. Here we describe a chemistry experiment that combines science and engineering principles while introducing basic polymer and green chemistry concepts. Using medical sutures as a platform for…

Reck, Rebecca M. – IEEE Transactions on Education, 2017
Course objectives, like research objectives and product requirements, help provide clarity and direction for faculty and students. Unfortunately, course and laboratory objectives are not always clearly stated. Without a clear set of objectives, it can be hard to design a learning experience and determine whether students are achieving the intended…

Marble, Jacob Earl – ProQuest LLC, 2017
This study investigated whether or not lab type, traditional lab or virtual lab, influenced students' engagement. To measure student engagement six students were videoed over the course of an 18-week semester while conducting 10 lab experiments. To analyze student engagement, a systematic visual comparison in the tradition of single case research…

Garduño-Aparicio, Mariano; Rodríguez-Reséndiz, Juvenal; Macias-Bobadilla, Gonzalo; Thenozhi, Suresh – IEEE Transactions on Education, 2018
This paper presents a robot prototype for an undergraduate laboratory program designed to fulfill the criteria laid out by ABET. The main objective of the program is for students to learn some basic concepts of embedded systems and robotics, and apply them in practice. For that purpose, various practical laboratory exercises were prepared to teach…

Novick, Laura R.; Catley, Kefyn M. – Journal of Biological Education, 2018
The ability to interpret and reason from Tree of Life diagrams is a key component of twenty-first century science literacy. This article reports on the authors' continued development of a multifaceted research-based curriculum--including an instructional booklet, lectures, laboratories and a field activity--to teach such tree thinking to biology…

Hill, Cynthia F. C. – ProQuest LLC, 2018
The science education literature documents the benefits of student engagement with scientific practices. Lab reports could be an opportunity for developing student reasoning, but often prioritize learning terminology and genre-specific writing. There is potential for instructors to give students feedback that helps them to engage with scientific…

Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with "business as usual." The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that…

Gomez-Sacristan, Angel; Sempere-Paya, Victor M.; Rodriguez-Hernandez, Miguel A. – IEEE Transactions on Education, 2016
Teaching in university engineering departments is currently facing a number of challenges, especially for those involved in the most innovative and dynamic areas of information and communication technology. Learning model developments that place greater weight on laboratory activities require investment in specific equipment that is often very…

Hendel, Samuel J.; Young, Elizabeth R. – Journal of Chemical Education, 2016
Electrochemical analysis is an important skill to teach in chemistry curricula because it is a critical tool in current high-impact chemical research. Electrochemistry enables researchers to analyze a variety of systems extending from molecules to materials that encompass research themes ranging from clean energy to substrate activation in…

Fonseca, Custódia S. C. – Journal of Chemical Education, 2016
Saccharin (1,2-benzisothiazole-3-one 1,1-dioxide) is an artificial sweetener used in the food industry. It is a cheap and easily available organic compound that may be used in organic chemistry laboratory classes for the synthesis of related heterocyclic compounds and as a derivatizing agent. In this work, saccharin is used as a starting material…

Borrell, Y. J.; Muñoz-Colmenero, A. M.; Dopico, E.; Miralles, L.; Garcia-Vazquez, E. – Biochemistry and Molecular Biology Education, 2016
A Citizen Science approach was implemented in the laboratory practices of Genetics at the University of Oviedo, related with the engaging topic of Food Control. Real samples of food products consumed by students at home ("students as samplers") were employed as teaching material in three different courses of Genetics during the academic…

Rossi, M.; Gratton, L. M.; Oss, S. – Physics Teacher, 2013
We discuss how compressed images created by modern digital cameras can lead to even severe problems in the quantitative analysis of experiments based on such images. Difficulties result from the nonlinear treatment of lighting intensity values stored in compressed files. To overcome such troubles, one has to adopt noncompressed, native formats, as…

Brom, Joseph M. – Journal of Chemical Education, 2017
The concept of wave-particle duality in quantum theory is difficult to grasp because it attributes particle-like properties to classical waves and wave-like properties to classical particles. There seems to be an inconsistency involved with the notion that particle-like or wave-like attributes depend on how you look at an entity. The concept comes…

Kimaru, Irene; Koether, Marina; Chichester, Kimberly; Eaton, Lafayette – Journal of Chemical Education, 2017
Analytical method transfer (AMT) and dissolution testing are important topics required in industry that should be taught in analytical chemistry courses. Undergraduate students in senior level analytical chemistry laboratory courses at Kennesaw State University (KSU) and St. John Fisher College (SJFC) participated in development, validation, and…
