Evolutionary trees are powerful tools used in modern biological research, and also commonly used in textbooks and classroom instruction. Studies have shown that K-14 students have difficulties interpreting evolutionary trees. To improve student learning about this topic, it is essential to teach them how to understand and use trees like professional biologists. Unfortunately, few currently used teaching frameworks for evolution instruction are designed for this purpose. In this study we developed the Model of the Use of Evolutionary Trees (MUET), a conceptual model that characterizes how evolutionary trees were used by professional biologists as represented in their research publications. The …

Guidelines To Avoid Typical Difficulties According To The Rubric For Experimental Design (Red), Annwesa Dasgupta, Nancy Pelaez
PIBERG Publications
Experimental design is an important component of undergraduate biology education as it generates knowledge of biology. Despite its importance, there is limited information about what students actually learn from designing experiments. Dasgupta et al (2014) reported on the development and validation of a Rubric for Experimental Design (RED), informed by a literature review and empirical analysis of thousands of undergraduate biology students’ responses to three published assessments. The RED is a useful probe for five major areas of experimental design abilities: the variable properties of an experimental subject; the manipulated variables; measurement of outcomes; accounting for variability; and the scope …

Physical Actvity In Pregnant Rat Dams Reduces Mammary Tumor Formation In Offspring, Leon Clah
Open Access Theses
Breast cancer is the most frequently diagnosed cancer and a leading cause of cancer death among women. Lifestyle factors such as physical activity and diet play a role in attenuating the incidence of breast cancer. Current research is beginning to show that exercise during pregnancy can convey long term health benefits to offspring. In light of these studies, the goal of this project was to determine if maternal physical activity during pregnancy could lead to reduced mammary tumor development in female offspring. Towards this goal, female Sprague Dawley rats were divided into two groups, sedentary and exercise, with the exercise …

This study follows the evolution of a single biology course designed for non-science majors. In its original design, the course used only traditional pedagogical techniques, such as lecture and textbook homework assignments. Over several iterations of the course, the class combined problem-based learning (PBL) and service learning to better support student knowledge. For this study, our goal was for students to learn biology concepts as they engaged in a lake cleanup project within the greater Chicago metropolitan area. Data sources consisted of pretest, posttest, and final exam scores to assess learning. The results suggest the combination of PBL and service …
