Kudish, Philip; Schlag, Erin; Kaplinsky, Nicholas J. – Bioscene: Journal of College Biology Teaching, 2015
We developed a multi-week laboratory in which college-level introductory biology students investigate Mendel's stem length phenotype in peas. Students collect, analyze and interpret convergent evidence from molecular and physiological techniques. In weeks 1 and 2, students treat control and experimental plants with Gibberellic Acid (GA) to…

Darling, Randi – Bioscene: Journal of College Biology Teaching, 2014
Evolution is a unifying concept within biology. In fact, Dobzhansky, a noted evolutionary biologist, argued, "Nothing in biology makes sense except in the light of evolution" (Dobzhansky, 1973). However, often students have misconceptions about evolution. There are a number of available activities where students use tools (representing…

Nogaj, Luiza A. – Bioscene: Journal of College Biology Teaching, 2014
A nine-week laboratory project designed for a sophomore level molecular biology course is described. Small groups of students (3-4 per group) choose a tumor suppressor gene (TSG) or an oncogene for this project. Each group researches the role of their TSG/oncogene from primary literature articles and uses bioinformatics engines to find the gene…

Weatherred, Wayland; Carlson, Darby J.; Carlson, Kimberly A. – Bioscene: Journal of College Biology Teaching, 2014
Proper hand hygiene accompanied with environmental surface disinfection provides a comprehensive approach to control and prevent respiratory and gastrointestinal illness in schools, hospitals, work environments, and the home. The persistent non-pathogenic Nora virus common in "Drosophila melanogaster" provides a horizontally transmitted…

Infanti, Lynn M.; Wiles, Jason R. – Bioscene: Journal of College Biology Teaching, 2014
This investigation evaluated the effects of exposure to the "Evo in the News" section of the "Understanding Evolution" website on students' attitudes toward biological evolution in undergraduates in a mixed-majors introductory biology course at Syracuse University. Students' attitudes toward evolution and changes therein were…

Hilvano, Nestor T.; Mathis, Karen M.; Schauer, Daniel P. – Bioscene: Journal of College Biology Teaching, 2014
Engaging students in discussion and creating high impact teaching and learning practices are a challenge in every classroom. Small group discussion and poster presentations were used to solve case-based problems to highlight issues for the learner and to allow each student to demonstrate understanding and application of theory to real life…

Basey, John M.; Maines, Anastasia P.; Francis, Clinton D.; Melbourne, Brett – Bioscene: Journal of College Biology Teaching, 2014
We examined the effects of documenting observations with digital imaging versus hand drawing in inquiry-based college biodiversity labs. Plant biodiversity labs were divided into two treatments, digital imaging (N = 221) and hand drawing (N = 238). Graduate-student teaching assistants (N = 24) taught one class in each treatment. Assessments…

Clark, Jordan M.; Rollins, Adam W.; Smith, Philip – Bioscene: Journal of College Biology Teaching, 2014
Journal clubs have been used to advance students' scientific skills beyond basic knowledge and comprehension, but students often view the traditional format of analyzing reported data and experimental design as laborious and intimidating. As such, the traditional approach can diminish student engagement and enthusiasm for the value of scientific…

Burton, Rebecca S. – Bioscene: Journal of College Biology Teaching, 2014
Textbooks are required in most introductory college science courses, but students may not be benefitting from the textbooks as much as their instructors might hope. Word use in the textbooks may influence textbook effectiveness. I tested whether either the amount of technical vocabulary or the readability had a significant effect on students'…

Pearce, Amy R.; Sale, Amanda Lovelace; Srivatsan, Malathi; Beck, Christopher W.; Blumer, Lawrence S.; Grippo, Anne A. – Bioscene: Journal of College Biology Teaching, 2013
We developed an inquiry-based biology laboratory exercise in which undergraduate students designed experiments addressing whether material from the neem tree ("Azadirachta indica") altered bean beetle ("Callosobruchus maculatus") movements and oviposition. Students were introduced to the bean beetle life cycle, experimental…

Belanger, Rachelle M.; Conant, Stephanie B.; Grabowski, Gregory M. – Bioscene: Journal of College Biology Teaching, 2013
Rats can be used as a model organism to teach physiological concepts in a laboratory setting. This article describes a two-part laboratory that introduces students to hypothesis testing, experimental design, the appropriate use of controls and surgical techniques. Students perform both a castration and sham-control surgery on male rats and test…

Davis, Thomas A. – Bioscene: Journal of College Biology Teaching, 2013
Students learn best by being actively engaged in the learning process. This essay describes a teaching technique where students generate their own questions about a course topic. This occurs at the beginning of each new section of a course. The instructor works with the class to answer the students' own questions throughout that section of…

Flannery, Maura C. – Bioscene: Journal of College Biology Teaching, 2013
Herbaria are collections of preserved plants specimens, some of which date back to the 16th century. They are essential to botanical research, especially in systematics. They can also be important historical documents. The collections of Lewis and Clark, Carolus Linnaeus, and Charles Darwin, to name a few, are primary sources for the study of…

Roy, Nicole M. – Bioscene: Journal of College Biology Teaching, 2013
RNA interference (RNAi) is a powerful technology used to knock down genes in basic research and medicine. In 2006 RNAi technology using "Caenorhabditis elegans" ("C. elegans") was awarded the Nobel Prize in medicine and thus students graduating in the biological sciences should have experience with this technology. However,…

Hallyburton, Chad L.; Lunsford, Eddie – Bioscene: Journal of College Biology Teaching, 2013
The history of learning biology through distance education is documented. A review of terminology and unique problems associated with biology instruction is presented. Using published research and their own teaching experience, the authors present recommendations and best practices for managing biology in distance-based formats. They offer ideas…
