Ekunsanmi, Toye J. – Bioscene: Journal of College Biology Teaching, 2005
The Kirby-Bauer method is regularly used to test bacterial susceptibility to antibiotics, and is often employed in the classroom for teaching this concept. In this exercise, additional materials and instructions were given to students for the preparation of garlic extract and loading on blank BBL paper discs. They were further instructed to test…

Dick, Timothy T.; Watson, Jason – Bioscene: Journal of College Biology Teaching, 2005
Introductory biology laboratory experiences frequently rely on preserved chordates for anatomical study. Unfortunately, these preserved organisms rarely reflect the appearance of a living creature. Since community colleges are generally prohibited the use of live chordates, this paper describes the autopsy of a "road kill" squirrel to facilitate…

Lefebvre, Daniel D.; Chenaux, Peter; Edwards, Maureen – Bioscene: Journal of College Biology Teaching, 2005
An easily implemented practical exercise in applied science for biology students is presented that uses fungi to degrade an azo-dye. This is an example of bioremediation, the employment of living organisms to detoxify or contain pollutants. Its interdisciplinary nature widens students' perspectives of biology by exposing them to a chemical…

Slish, Donald F. – Bioscene: Journal of College Biology Teaching, 2005
This project involved the use of two small, closely matched non-majors introductory biology classes to test the use of the Jigsaw method of teaching vs. a passive, instructor-oriented model of teaching. In this study, the Jigsaw method was used as a jumping off point for the teaching-learning of the material. Students were to learn the concepts of…

Curto, Karen; Bayer, Trudy – Bioscene: Journal of College Biology Teaching, 2005
A collaborative effort between biology and communication instructors to facilitate speaking skills for senior biology majors resulted in improved organization, clarity and confidence in delivering an oral scientific presentation. But this instruction also favorably impacted students' scientific writing. This benefit seems best attributed to…

Elwess, Nancy L.; Vogt, F. Daniel – Bioscene: Journal of College Biology Teaching, 2005
Conditions producing stress are present in all colleges and universities. In this paper we report on an investigation utilizing heart rate as an indicator of stress in students when participating in activities encountered in a college classroom or laboratory. The activities included presenting an oral report, taking an exam, and participating in a…

Phillips, Gregory W. – Bioscene: Journal of College Biology Teaching, 2005
This study examined the breakfast eating habits of 1,259 college students over an eleven year period to determine if eating breakfast had an impact upon their grade on a General Biology exam. The study determined that there was a significant difference in the performance on the exam with a higher percent of the participants, who had eaten…

Marbach-Ad, Gili; Arviv-Elyashiv, Rinat – Bioscene: Journal of College Biology Teaching, 2005
What should an undergraduate student in a specific discipline gain in the course of his/her studies? All too often, the answer to this question is not formally defined, and answers differ, sometimes largely, even between members of the same academic faculty. In our study we focused on the life sciences faculty and explored both undergraduate…

Shingles, Richard; Feist, Theron; Brosnan, Rae – Bioscene: Journal of College Biology Teaching, 2005
To build a learning community, the General Biology faculty at Johns Hopkins University conducted collaborative, problem-based learning assignments outside of class in which students are assigned to specific areas on campus, and gather and report data about their area. To overcome the logistics challenges presented by conducting such assignments in…

Vondrasek, Joanna R.; Antonovics, Janis; Taylor, Douglas R. – Bioscene: Journal of College Biology Teaching, 2004
We have developed a laboratory course that demonstrates how evolution can be taught as a participatory, investigative science at the undergraduate college or advanced secondary high school level. The course emphasizes the applied importance of evolution to areas such as medicine and agriculture. Because many instructors face budgetary or other…

Stover, Shawn K.; Mabry, Michelle L. – Bioscene: Journal of College Biology Teaching, 2004
Program-level assessment of the biology curriculum at a small liberal arts college indicates progress in the development of communication skills and content knowledge. The authors propose a mechanism to provide more research opportunities for students, giving them all the tools necessary to do science. (Contains 5 figures.)

Fitch, Greg K. – Bioscene: Journal of College Biology Teaching, 2004
The mechanism by which air enters the mammalian lung is difficult for many students of physiology. In particular, some students have trouble seeing how pressure can be transmitted through a fluid such as the intrapleural fluid and how the magnitude of that pressure can change. A Cartesian diver, an old-time child's toy, may be used as a visual aid…

Brett, William J.; Mulkey, Timothy – Bioscene: Journal of College Biology Teaching, 2004
The paper presents a teaching regime and evaluation criteria for a general education course in biology. The purpose of the course is to provide students with biological information to help them understand problems facing humans and some of the social and ethical aspects of these problems. Using input from students concerning what constitutes a…

Yarden, Hagit; Marbach-Ad, Gili; Gershoni, Jonathan M. – Bioscene: Journal of College Biology Teaching, 2004
In our study, we focused on the conceptual understanding of the concepts and processes presented in the first lectures of an introductory course in cellular biology for biology majors. The study topic we considered was, "the structure of DNA and the functions of nucleotides". One hundred and eighteen students were asked to prepare concept maps…

Egan, Todd P.; Meekins, J. Forrest; Maluso, Diane – Bioscene: Journal of College Biology Teaching, 2004
This laboratory exercise affords students a hands-on experience learning about traditional dyes, fiber strength, and paper making. It is economical, simple to prepare, provides satisfactory results, and is student friendly. Dyes were extracted from plant leaves, stems, roots, and fruits. Hard-boiled eggs were place in the dyes for 15 minutes to…
