Hill, Brent J. F.; Goodman, Ian; Moran, William M. – Bioscene: Journal of College Biology Teaching, 2011
Most undergraduate physiology texts describe veins simply as reservoirs for blood and conduits for return of blood to the heart. This article describes a laboratory exercise that can be performed by students to demonstrate that veins are much more than reservoirs and conduits for blood flow: they possess a dynamic rhythmic contraction. In this…

Burton, Rebecca S. – Bioscene: Journal of College Biology Teaching, 2011
When selecting a textbook, college instructors must weigh a variety of factors. One is whether the text is written at a level that is accessible to one's students. An important factor in this is how many technical words are used. I developed an index to calculate logodiversity, a term I coined that reflects the number of technical words and the…

Shanks, Ryan A.; Southard, E. Megan; Tarnowski, Laura; Bruster, Matthew; Wingate, Stacia W.; Dalman, Nancy; Lloyd, Steven A. – Bioscene: Journal of College Biology Teaching, 2011
This article describes a laboratory experience utilizing videos to engage students in hypothesis-driven experimentation in behavioral neuroscience. It provides students with an opportunity to investigate the effects of chronic methamphetamine exposure on aggression in adult mice using a resident-intruder paradigm. Instructors and students only…

Bee, Mary Tracy; Montante, James; Lanigan, Kate; Andrzejak, Michelle; Grabowski, Greg – Bioscene: Journal of College Biology Teaching, 2011
Alternative teaching styles provide a unique and rewarding approach to reinforcing student knowledge and developing social skills. An approach that we implemented required students from the ecology class to organize and present information at the university-wide Earth Day celebration and exposition. In addition to the informational and research…

Elliott, Shannon S.; Winter, Peggy A. – Bioscene: Journal of College Biology Teaching, 2011
The split-root technique produces a plant with two equal root masses. Traditionally, the two root masses of the single plant are cultivated in adjacent pots with or without roots from competitors for the purpose of elucidating habitat preferences. We have tailored this technology for the classroom, adjusting protocols to match resources and time…

Jensen, Jamie L. – Bioscene: Journal of College Biology Teaching, 2011
Higher education faculty are not held to the same standard of pedagogical preparation as primary and secondary teachers. This perspectives essay points out the difference in pedagogical preparations between higher education faculty and high school teachers. The essay highlights research indicating the importance of pedagogical training, offers…

Davis, Thomas A. – Bioscene: Journal of College Biology Teaching, 2011
Loras College senior biology and biology research majors are required to take a comprehensive exam, give an oral presentation, write this talk into their thesis and participate in an exit interview with a non-biology faculty member before they graduate. Details of these capstone experiences will be discussed further. Other capstone experiences…

Jones-Held, Susan; Paoletti, Robert; Glick, David; Held, Michael E. – Bioscene: Journal of College Biology Teaching, 2010
In this article we describe a multi-week investigative laboratory in microbial ecology/diversity and nitrogen cycling that we have used in our introductory biology course. This module encourages active student involvement in experimental design, using the scientific literature and quantitative analysis of large data sets. Students analyze soil…

Carlin, Joel L. – Bioscene: Journal of College Biology Teaching, 2010
Dissections of single species (e.g., fetal pig) are a common student learning activity in introductory biology courses. Such dissections demonstrate location of anatomical parts and provide dissection practice but provide less opportunity for student critical thinking, numeracy and demonstration of the scientific method. A comparative anatomy lab…

Parent, Beth A.; Marbach-Ad, Gili; Swanson, Karen V.; Smith, Ann C. – Bioscene: Journal of College Biology Teaching, 2010
Scientific literature was used to give a research oriented context to our immunology lab course. Immunology lab, a senior level course (60 students/year) was formerly taught in a traditional mode, with exercises aimed at learning lab protocols. To engage students in understanding we connected the protocols to their use as reported in research…

Shumate, Alice M.; Windsor, Aaron J. – Bioscene: Journal of College Biology Teaching, 2010
The increase in publications presenting molecular evolutionary analyses and the availability of comparative sequence data through resources such as NCBI's GenBank underscore the necessity of providing undergraduates with hands-on sequence analysis skills in an evolutionary context. This need is particularly acute given that students have been…

Palsule, Vrushalee; Coric, Dijana; Delancy, Russell; Dunham, Heather; Melancon, Caleb; Thompson, Dennis; Toms, Jamie; White, Ashley; Shultz, Jeffry – Bioscene: Journal of College Biology Teaching, 2010
A clear understanding of basic gene structure is critical when teaching molecular genetics, the central dogma and the biological sciences. We sought to create a gene-based teaching project to improve students' understanding of gene structure and to integrate this into a research project that can be implemented by instructors at the secondary level…

Yule, Jeffrey V.; Wolf, William C.; Young, Nolan L. – Bioscene: Journal of College Biology Teaching, 2010
Effectively integrating writing into biology classes gives students the opportunity to develop a better understanding of and engagement with course content. Yet many instructors remain reluctant to emphasize writing. Some are concerned about the time commitment writing assessment requires. Others shy away from emphasizing writing in their classes…
