Constructing explanations is an essential skill for all science learners. The goal of this project was to model the key components of expert explanation of molecular and cellular mechanisms. As such, we asked: What is an appropriate model of the components of explanation used by biology experts to explain molecular and cellular mechanisms? Do explanations made by experts from different biology subdisciplines at a university support the validity of this model? Guided by the modeling framework of R. S. Justi and J. K. Gilbert, the validity of an initial model was tested by asking seven biologists to explain a molecular …
The Role Of Entomology In Environmental And Science Education: Comparing Outreach Methods For Their Impact On Student And Teacher Content Knowledge And Motivation, Faith J. Weeks
Open Access Dissertations
Outreach programming can be an important way for local students and teachers to be exposed to new fields while enhancing classroom learning. University-based outreach programs are offered throughout the country, including most entomology departments as few individuals learn about insects in school and these programs can be excellent sources of entomological education, as well as models to teach environmental and science education. Each department utilizes different instructional delivery methods for teaching about insects, which may impact the way in which students and teachers understand the insect concepts presented. To determine the impact of using entomology to enhance science and environmental …
Physical Actvity In Pregnant Rat Dams Reduces Mammary Tumor Formation In Offspring, Leon Clah
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 …
Mach: A Model For Explaining Molecular And Cellular Mechanisms, Caleb M. Trujillo
Mach: A Model For Explaining Molecular And Cellular Mechanisms, Caleb M. Trujillo
Open Access Dissertations
Biologists use mechanistic explanations to understand behaviors of the immense complexity of molecular and cellular systems. In undergraduate biology courses, students are expected to explain molecular and cellular mechanisms, but teaching this skill presents many challenges due to the highly abstract, intangible nature of the cellular world, the influence of everyday language, and the tendency of students to overestimate how much they can explain. Therefore, across three studies this dissertation addresses these obstacles to teach undergraduate biology students to explain molecular and cellular mechanisms. ^ The first step was to model how biology experts explain molecular and cellular mechanisms, and …
