University of Nebraska State Museum: Mammalogy Papers
First paragraph:
On 30 March 2018, the science of mammalogy and the American Society of Mammalogists lost one of the most influential figures of the last half-century. Robert James Baker died quietly at his home in Lubbock, Texas (Fig. 1). He was born on 8 April 1942 to James Simeon Baker and Laura Cooper in Warren, Arkansas. His father was killed during World War II and his mother remarried, resulting in his growing up with six half-siblings. According to Robert’s autobiography in Going afield (330—number refers to specific publication in “Bibliography”), he spent a good deal of his youth with …

High Cognitive Demand Examples In Precalculus: Examining The Work And Knowledge Entailed In Enactment, Erica R. Miller
High Cognitive Demand Examples In Precalculus: Examining The Work And Knowledge Entailed In Enactment, Erica R. Miller
Department of Mathematics: Dissertations, Theses, and Student Research
Historically, pass rates in undergraduate precalculus courses have been dismally low and the teaching practices and knowledge of university instructors have been understudied. To help improve teaching effectiveness and student outcomes in undergraduate precalculus courses, I have studied the cognitive demand of enacted examples. The purpose of this dissertation is to examine the pedagogical work and mathematical knowledge entailed in the enactment of high cognitive demand examples in a three-part study. To answer my research questions, I conducted classroom observations as well as pre- and post-observation interviews with seven graduate student instructors at a large public R1 university in the …
The Impact Of Mentoring On Life Science Undergraduate Mentors, Kari Nelson
The Impact Of Mentoring On Life Science Undergraduate Mentors, Kari Nelson
Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research
Universities are increasingly encouraging their undergraduates to become mentors to others, yet relatively little research has been done to empirically understand the impact of this work on the mentors themselves. Therefore, the overall goals of this work were: (1) To evaluate the types of studies that have been conducted on the impacts of serving as an undergraduate mentor; (2) To examine the methodological rigor of recent studies and make recommendations for improvement; and (3) To asses if serving as an undergraduate mentor impacted the critical thinking of the mentors, using a valid and reliable instrument, the California Critical Thinking Skills …

The purpose of this study was to investigate implementation of an early intervention mastery activity during the first two weeks of college algebra and precalculus courses at a large U.S. public university. Statistical modeling of (N = 935) students’ performance in the courses, including a logistic regression model of pass/fail course achievement with students’ high school rank, ACT Mathematics scores, and performance on the intervention as explanatory variables, suggested significant independent differences in course performance across performance levels on the early mastery activity. An evaluation of diagnostic validity for the model yielded a 19% false negative rate (predicted to …
