Effects Of Historical Story Telling On Student Understanding Of Nos And Mendelian Genetics, Cody Tyler Williams
Dissertations
Science education researchers have long advocated the central role of the nature of science (NOS) for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological claims associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. Many teachers are uncomfortable with taking time away from traditional science content instruction. One promising method for teaching NOS and science content involves an explicit and reflective approach …

Using Concept Maps To Monitor Knowledge Structure Changes In A Science Classroom, Leah J. Cook
Dissertations
The aim of this research is to determine what differences may exist in students’ structural knowledge while using a variety of concept mapping assessments. A concept map can be used as an assessment which connects concepts in a knowledge domain. A single assessment may not be powerful enough to establish how students’ new knowledge relates to prior knowledge. More research is needed to establish how various aspects of the concept mapping task influence the output of map creation by students. Using multiple concept maps and pre-instruction and postinstruction VNOS instruments during a 16-week semester, this study was designed to investigate …
