Marbach-Ad, Gili; Ribke, Melina; Gershoni, Jonathan M. – Bioscene: Journal of College Biology Teaching, 2006
This study aimed to facilitate students' entrance to an introductory cell biology course for biology majors. The most prominent difficulty in this introductory course, is students' poor background-knowledge, such as a lack of understanding of very basic concepts and terms, and the huge differences in students' background knowledge. In order to…

Preszler, Ralph W. – Bioscene: Journal of College Biology Teaching, 2006
Students who chose to enroll in a supplemental course associated with a large biology lecture performed better on lecture exams than those students who chose not to enroll in the supplemental course. Sections of the supplemental course were taught with instructor-centered methods prior to some exams, student-centered methods prior to other exams,…

Chemotti, Diana C.; Davis, Sarah N.; Cook, Leslie W.; Willoughby, Ian R.; Paradise, Christopher J.; Lom, Barbara – Bioscene: Journal of College Biology Teaching, 2006
Malathion is an organophosphorus insecticide, which is often sprayed to control mosquitoes. When applied to aquatic habitats, malathion can also influence the embryogenesis of non-target organisms such as frogs and fish. We modified the frog embryo teratogen assay in "Xenopus" (FETAX), a standard toxicological assay, into an investigative…

Wollard, Laura; Klein, Benjamin; Carlson, Darby J.; Carlson, Kimberly A. – Bioscene: Journal of College Biology Teaching, 2006
A major challenge in teaching the process of science to students is designing and implementing laboratory activities that emulate what is actually done in a research laboratory. To facilitate this effort, science educators have been encouraged to design exercises that span multiple laboratory periods, encourage independent thinking, promote…

Tessier, Jack T.; Penniman, Clayton A. – Bioscene: Journal of College Biology Teaching, 2006
There is a collective need to increase the use of inquiry-based instruction at the college level. This paper provides of an example of how inquiry was successfully used in the laboratory component of an undergraduate course in microbial ecology. Students were offered a collection of field and laboratory methods to choose from, and they developed a…

Lunsford, Eddie; Bolton, Kimberly – Bioscene: Journal of College Biology Teaching, 2006
This paper presents the course of action and outcome of a teacher-based action research project concerning development and evaluation of an online introductory biology course for non-majors. The research took place in a small community college and compared online and traditional instructional formats. A course was developed in an entirely…

Daempfle, Peter A. – Bioscene: Journal of College Biology Teaching, 2006
The majority of undergraduates lack advanced reasoning patterns, which are necessary for significant achievement in college science courses. The purpose of this paper is to review the studies of various instructional practices in introductory college biology courses that claim to develop reasoning. Most of these were non-traditional,…

Weihe, Paul – Bioscene: Journal of College Biology Teaching, 2006
A discussion of the Demographic Transition is included in many Environmental Biology or Environmental Science classes. The Demographic Transition occurs as a nation becomes more urban and wealthy, and was widely observed in the twentieth century. The phenomenon includes decreasing family size (fewer children) across generations. In this classroom…

Rutledge, Michael L.; Mathis, Philip M.; Seipelt, Rebecca L. – Bioscene: Journal of College Biology Teaching, 2005
As students apply their knowledge of scientific concepts and of science as a method of inquiry, learning becomes relevant. This laboratory exercise is designed to foster students' understanding of the genetics of quantitative traits and of the nature of science as a method of inquiry by engaging them in a real-world business scenario. During the…

Greene, Kathleen; Donovan, Sam – Bioscene: Journal of College Biology Teaching, 2005
In the process of designing and field-testing bioinformatics curriculum materials, we have adopted a three-stage, progressive model that emphasizes collaborative scientific inquiry. The elements of the model include: (1) context setting, (2) introduction to concepts, processes, and tools, and (3) development of competent use of technologically…

Brodl, Mark R. – Bioscene: Journal of College Biology Teaching, 2005
This project presents a model for the development of an innovative, highly-experimental teaching laboratory course that centers upon collaborative efforts between recent alumni currently enrolled in Ph. D. programs (consultants) and current faculty. Because these consultants are involved in cutting-edge research, their combined talents represent a…

Wallace, Robert L. – Bioscene: Journal of College Biology Teaching, 2005
A simple laboratory exercise is presented that follows the population growth of the common vinegar eel, "Turbatrix aceti" (Nematoda), in a microcosm using a simple culture medium. It lends itself to an exercise in a single semester course. (Contains 4 figures.)

Elwess, Nancy L.; Butterfield, Savanna R.; Charles, Amanda; DeVeaugh, Maxine C.; Lu, Gloria J.; Shafqat, Hira; Watts, Andrew – Bioscene: Journal of College Biology Teaching, 2005
The fictional case study presented here is not based on one case, but is actually based on several cases. College students enrolled in a bioethics course for non-majors wrote it. The case entails the thought processes and decision-making involved in order to save one child suffering from a genetic disorder by producing another child, a "designer…

Johnson, David; Brett, William – Bioscene: Journal of College Biology Teaching, 2005
Today, more than at any other time in human history, biologists are or should be concerned about the morality of biological research and newly developed technologies. Two questions confront any scientist or science student concerned about morality and the life sciences. Is there some theoretical framework that might be used to assist in deciding…
