A Model Of The Use Of Evolutionary Trees (Muet) To Inform K-14 Biology Education, Yi Kong, Ankita Thawani, Trevor R. Anderson, Nancy Pelaez

PIBERG Publications

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 …


Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez Aug 2016

Effects Of Soil Erosion Barriers On Percent Cover And Sediment Size, Michael Perez

STAR Program Research Presentations

Ranching began on Santa Rosa Island in the 1840’s, introducing nonnative megafauna that put selective grazing pressures on endemic species. Dense groves of island oak (Q. tomentella) are aid in sediment deposition and retention. A current restoration effort, involved installing soil erosion barriers, known as wattles, to prevent sediment from being lost upslope and recruit plant growth whose root systems could further stabilize the slope. This experiment was designed to compare percent cover of vegetation growth in areas with and without soil erosion barriers. This was done using the line intercept method (n=42) on three meter transects, measuring …


Student Perceptions Of Interactive Whiteboards In A Biology Classroom, Christina Schut Jan 2007

Student Perceptions Of Interactive Whiteboards In A Biology Classroom, Christina Schut

Master of Education Research Theses

This qualitative study provides student perceptions of interactive whiteboard (IWB) use in a secondary biology classroom. The use of the IWB was alternated with the overhead on an ABAB and BABA design in two classrooms. The study was based on semi-structured interviews of thirty-six individuals, representing a sample of rural, high school students. Interview questions focused on three constructs: benefits, limitations, and suggestions for improvement. Analyzing the results ascertained that students found the IWB to be interesting because it was engaging and offered multimedia aspects. Students also reported the IWB to improve instruction through enhanced visuals and notes. Limitations and …
