Animal dissections are essential parts of anatomy/zoology courses, but their effectiveness is influenced by student attitudes and emotions. Here we examined attitudes toward dissections in 397 prospective biology teachers enrolling two Slovak universities. Perceived disgust of dissections negatively correlated with other attitudes toward…

Wedlich, Richard C.; Libera, Agata E.; Pires, Amanda; Tellarini, Cassandra – Journal of Chemical Education, 2013
A clear understanding of how "raw data" is defined, recorded, and retained in the laboratory record is essential to the chemist employed in the laboratory compliant with the Good Laboratory Practices regulations. This article is intended to provide an understanding by drawing upon examples taken from the modern pharmaceutical analysis…

Wilson, Karl A.; Tan-Wilson, Anna – Biochemistry and Molecular Biology Education, 2013
Mass spectrometry (MS) has become an important tool in studying biological systems. One application is the identification of proteins and peptides by the matching of peptide and peptide fragment masses to the sequences of proteins in protein sequence databases. Often prior protein separation of complex protein mixtures by 2D-PAGE is needed,…

Noel, Geoffroy P.J.C. – Anatomical Sciences Education, 2013
Anatomy teaching is seeing a decline in both lecture and laboratory hours across many medical schools in North America. New strategies are therefore needed to not only make anatomy teaching more clinically integrated, but also to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the…

Vargas, R.; Johannesdottir, I. P.; Sigurgeirsson, B.; Porsteinsson, H.; Karlsson, K. AE. – Advances in Physiology Education, 2011
Recently, the zebrafish ("Danio rerio") has been established as a key animal model in neuroscience. Behavioral, genetic, and immunohistochemical techniques have been used to describe the connectivity of diverse neural circuits. However, few studies have used zebrafish to understand the function of cerebral structures or to study neural circuits.…

Hahn, Tobias; Huuk, Thiemo; Heuveline, Vincent; Hubbuch, Ju¨rgen – Journal of Chemical Education, 2015
Industrial purification of biomolecules is commonly based on a sequence of chromatographic processes, which are adapted slightly to new target components, as the time to market is crucial. To improve time and material efficiency, modeling is increasingly used to determine optimal operating conditions, thus providing new challenges for current and…

Marshak, David W.; Oakes, Joanne; Hsieh, Pei-Hsuan; Chuang, Alice Z.; Cleary, Leonard J. – Anatomical Sciences Education, 2015
At the University of Texas Houston Medical School, a rotational dissection system was introduced to improve coordination between the Gross Anatomy and the Introduction to Clinical Medicine (ICM) courses. Six students were assigned to each cadaver and divided into two teams. For each laboratory, one team was assigned to dissect and the other to…

Dissections of human organs and animals are an important part of medical and science education but students usually express negative emotions towards dissections. Some studies show a negative influence of disgust and anxiety on motivation, interest and achievement. Therefore, reducing anxiety and disgust should be an important aim. As humor can…

Harman, Gonca; Cokelez, Aytekin; Dal, Burckin; Alper, Umut – Universal Journal of Educational Research, 2016
The aim of this study was to examine pre-service science teachers' views about laboratory applications in science education and how their views changed through laboratory applications that were carried out for two semesters. 63 (52 females, 11 males) pre-service teachers participated in the study. The study was carried out by using pre-test and…

Reardon, Ryan A.; Sharer, J. Daniel – American Biology Teacher, 2012
This report describes a novel, inquiry-based learning plan developed as part of the GENA educational outreach project. Focusing on mitochondrial genetics and disease, this interactive approach utilizes pedigree analysis and laboratory techniques to address non-Mendelian inheritance. The plan can be modified to fit a variety of educational goals…

Haspel, Carol; Motoike, Howard K.; Lenchner, Erez – Anatomical Sciences Education, 2014
After a considerable amount of research and experimentation, cat dissection was replaced with rat dissection and clay modeling in the human anatomy and physiology laboratory curricula at La Guardia Community College (LAGCC), a large urban community college of the City University of New York (CUNY). This article describes the challenges faculty…

Bott, Tina M.; Wan, Hayley – Journal of Chemical Education, 2013
Students sometimes have difficulty grasping the importance of when and how basic distillation techniques, column chromatography, TLC, and basic spectroscopy (IR and NMR) can be used to identify unknown compounds within a mixture. This two-part experiment uses mixtures of pleasant-smelling, readily available terpenoid compounds as unknowns to…

Skinner, Michelle D. – ProQuest LLC, 2013
Cadaver dissection has been a central part of the education of medical professionals for centuries. Throughout that time, anatomists have claimed that dissection is a learning experience rich with life lessons encompassing more than simply gross anatomy. Yet, no published empirical data exist of the long-term impact that dissection has on medical…

White, Harold B., III; Usher, David C. – Biochemistry and Molecular Biology Education, 2015
Undergraduates having their first research experience frequently have little idea of what to expect. Institutions offering summer research experiences attempt to address this issue through programs that introduce students to the process and culture of science. However, didactic approaches frequently bore students who prefer more interactive…

A multivitamin tablet and liquid are analyzed for the elements calcium, magnesium, iron, zinc, copper, and manganese using atomic absorption spectrometry. Linear calibration and standard addition are used for all elements except calcium, allowing for an estimate of the matrix effects encountered for this complex sample. Sample preparation using…
