Erk, Kendra A.; Rhein, Morgan; Krafcik, Matthew J.; Ydstie, Sophie – Journal of Chemical Education, 2015
An educational activity is described in which the structure and physical properties of disposable plastic cups were directly related to the method of processing. The mechanical properties of specimens cut from the walls of poly(ethylene terephthalate) (PETE) cups, oriented parallel and perpendicular to the thermoforming direction, were measured in…

Nahra, Fady; Riant, Olivier – Journal of Chemical Education, 2015
A modified total synthesis of (S)-goniothalamin is described for an advanced course in organic chemistry. This experiment gives students an opportunity to handle organometallic reagents and perform an enzymatic kinetic resolution and a metathesis reaction, all in the same synthesis. Furthermore, students learn flame-drying techniques for the…

Hodgson, Jay Y. S.; Mateer, Scott C. – American Biology Teacher, 2015
The compound microscope is an important tool in biology, and mastering it requires repetition. Unfortunately, introductory activities for students can be formulaic, and consequently, students are often unengaged and fail to develop the required experience to become proficient in microscopy. To engage students, increase repetition, and develop…

Sidebottom, David – Physics Teacher, 2015
The general physics course that is taught in most departments as a service course for pre-med or pre-health students is undergoing a large shift in course content to better appeal to this group of learners. This revision also extends to the laboratory component, where more emphasis is being placed on teaching physics through biological examples.…

Puah, Yann-Yann; Ting, Su-Hie – Journal of Multilingual and Multicultural Development, 2015
The study examines the influence of gender, age and socio-economic status on attitudes of Foochow and Hokkien towards their ethnic language and Mandarin. The matched guise test results of 120 Foochow and 120 Hokkien participants in Kuching, Malaysia, showed positive attitudes towards Mandarin on all the 15 traits. The Hokkien participants were…

Yau, Hon Man; Haines, Ronald S.; Harper, Jason B. – Journal of Chemical Education, 2015
A "one-pot" method for acquiring kinetic data for the reactions of a series of substituted aromatic esters with potassium hydroxide using [supserscript 13]C NMR spectroscopy is described, which provides an efficient way to obtain sufficient data to demonstrate the Hammett equation in undergraduate laboratories. The method is…

Cai, Qijie; Lewis, Carrie L.; Higdon, Jude – Learning Assistance Review, 2015
An early-alert system (MavCLASS) was developed and piloted in a large gateway math class with 611 freshman students to identify academically at-risk students and provide alert messages. It was found that there was significant association between the alert messages students received and their visits to the university's tutor center. Further, the…

Williamson, Ben – Journal of Educational Administration and History, 2015
Policy innovation labs are emerging knowledge actors and technical experts in the governing of education. The article offers a historical and conceptual account of the organisational form of the policy innovation lab. Policy innovation labs are characterised by specific methods and techniques of design, data science, and digitisation in public…

Daniel Dante Anastasio – ProQuest LLC, 2015
The laboratory course is one of the most critical classes in any engineering program. Engineering by its very nature is a practical discipline, and the laboratory course is usually the first and only class where students are given the opportunity to apply the knowledge they are gaining in lecture courses to real-world equipment. As chemical…

Gorospe, Kelvin D.; Fox, Bradley K.; Haverkort-Yeh, Roxanne D.; Tamaru, Clyde S.; Rivera, Malia Ana J. – Journal of Geoscience Education, 2013
We present a hands-on, inquiry-based activity exploring how CO[subscript 2] input to seawater affects the skeletons of several species of reef-building corals and other marine organisms by testing for changes in pH and calcium ion concentrations. Originally developed to inspire and recruit high school students in the state of Hawai'i into the…

Wedlich, Richard C.; Libera, Agata E.; Pires, Amanda; Therrien, Matthew T. – Journal of Chemical Education, 2013
The Good Laboratory Practice (GLP) regulations were put into place in 1978. They establish a standard of practice to ensure that results from the nonclinical laboratory study reported to the U.S. Food and Drug Administration (FDA) are valid and that the study report accurately reflects the conduct of the study. While the GLP regulations promulgate…

Malkawi, Salaheddin; Al-Araidah, Omar – European Journal of Engineering Education, 2013
Laboratory experiments develop students' skills in dealing with laboratory instruments and physical processes with the objective of reinforcing the understanding of the investigated subject. In nuclear engineering, where research reactors play a vital role in the practical education of students, the high cost and long construction time of research…

Hayes, David; Widanski, Bozena – Journal of Chemical Education, 2013
A laboratory experiment is described that introduces students to "real-world" hazardous waste management issues chemists face. The students are required to define an analytical problem, choose a laboratory analysis method, investigate cost factors, consider quality-control issues, interpret the meaning of results, and provide management…

Bakhtiar, Ray – Journal of Chemical Education, 2013
Surface plasmon resonance (SPR) spectroscopy is a powerful, label-free technique to monitor noncovalent molecular interactions in real time and in a noninvasive fashion. As a label-free assay, SPR does not require tags, dyes, or specialized reagents (e.g., enzymes-substrate complexes) to elicit a visible or a fluorescence signal. During the last…

Hardee, John R.; Delgado, Bryan; Jones, Wray – Journal of Chemical Education, 2011
The kinetic parameters for the conversion of alpha-D-glucose to beta-D-glucose were measured using a blood glucometer. The reaction order, rate constant, and Arrhenius activation energy are reported for the noncatalyzed reaction and turnover number and Michaelis constant are reported for the reaction catalyzed by porcine kidney mutarotase. The…
