Random Number Simulations Reveal How Random Noise Affects The Measurements And Graphical Portrayals Of Self-Assessed Competency, Edward Nuhfer, Christopher Cogan, Steven Fleisher, Eric Gaze, Karl Wirth

Numeracy

Self-assessment measures of competency are blends of an authentic self-assessment signal that researchers seek to measure and random disorder or "noise" that accompanies that signal. In this study, we use random number simulations to explore how random noise affects critical aspects of self-assessment investigations: reliability, correlation, critical sample size, and the graphical representations of self-assessment data. We show that graphical conventions common in the self-assessment literature introduce artifacts that invite misinterpretation. Troublesome conventions include: (y minus x) vs. (x) scatterplots; (y minus x) vs. (x) column graphs aggregated as quantiles; line …

1. "Investigating The Impact Of Changes In Carbon Dioxide Concentration On Ecosystems", Sarah O'Leary-Driscoll, Crystal Randall

Ecosystem Disruption & Climate Change

Question: Does the concentration of carbon dioxide affect air temperature in a closed environment?

2a: "Illinois Carbon Dioxide Emissions Activity", Sarah O'Leary-Driscoll, Crystal Randall

Ecosystem Disruption & Climate Change

Your goal for this activity is to compare the different sources of carbon dioxide emissions, stemming from the consumption of fossil fuels, in Illinois. To do this you will be working with data spanning from 1980 to 2012.

Ecosystem Disruption & Climate Change

Information taken from: Dirzo, R. et al (2014). Defaunation in the Anthropocene. Science, 345(401).

Scientists estimate, conservatively, that there are 5 to 9 million different animal species on the planet. But that number is continually changing, and unfortunately, dropping, as we are likely losing 11,000- 58,000 species annually, and evidence suggests that on average, there has been a decline of about 28% in terms of numbers of individuals within a species over the last four decades. Both of these statistics are vitally important. The critical nature of the first is perhaps more obvious, as total loss of a species is …

The Greenhouse Effect: Does The Concentration Of Carbon Dioxide Affect The Air Temperature In A Closed Environment?, Climate Science Investigations - Nasa

Ecosystem Disruption & Climate Change

The purpose of this lesson is to investigate the effect of carbon dioxide (CO2) concentration on air temperature in a closed environment.

Zur Erinnerung An Den Mongolischen Säugetierforscher Namshil Chotolchuu (1935-1990) – Im Gedenken An Die Wiederkehr Seines 80. Geburtstages 2015, Michael Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Namshil Chotolchuu wurde am 20.01.1935 in Ulaanbaatar geboren. Sein Vater war in den 60er und 70er Jahren ein bekannter Schachmeister der Mongolei. Mit Chotolchuu verbinden uns sehr erfolgreiche und prägende gemeinsame Mongolisch-Deutsche Biologische Expeditionen und daraus resultierende Publikationen sowie eine lange Freundschaft.

Mit diesem Nachruf wollen wir an ein langes Kapitel der deutsch-mongolischen Zusammenarbeit mit Kollegen der Mongolischen Akademie der Wissenschaften und an einen Pionier der eigenständigen mongolischen Säugetierforschung erinnern, der in der internationalen Kooperation, im Team der Mongolisch-Deutschen Biologischen Expeditionen und im Schrifttum sowie ganz persönlich unvergessen bleibt.

What’S In A Gene: Undergraduates’ Ideas And Misconceptions About Gene Function, Justin M. Levaughn

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

The purpose of this study was to field test a two-tiered instrument including multiple-choice and short answer tasks to assess college students’ ideas and level of understanding in genetics. The instrument was constructed from previously tested assessment tasks and findings from the current research literature. Ninety-seven freshmen enrolled in a biology lab course were surveyed. Test validity and reliability were measured using Chronbach coefficients. Multiple-choice and short answer responses were analyzed using descriptive statistics to identify frequencies of answer selections. Written responses were independently evaluated using a five-point scoring rubric by three researchers to identify common misconceptions revealed in students’ …

Addendum To Encomia And Reflections, Clyde Jones (1935-2015): Encomium, Robert J. Baker, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

This is the authors' collective attempt to provide an encomium (an honest song of praise) for Clyde Jones. After some urging from the editors of this volume, the authors conspired to share some memories of Clyde.

Editors’ note: Due to various factors, this encomium was submitted too late to be included in the published memorial volume. However, in consideration of the relationship of the authors to Clyde Jones, we agreed to make this encomium available via electronic format as a supplement to the printed volume.

Enhancing The Stem Ecosystem Through Teacher-Researcher Partnerships, William E. Tapprich, Neal Grandgenett, Heather Leas, Steven N. Rodie, Robert Duncan Shuster, Chris Schaben, Christine E. Cutucache

Biology Faculty Publications

STEM faculty at the University of Nebraska at Omaha (UNO) have partnered with teachers and administrators in the Omaha Public Schools (OPS) to implement a Teacher-Researcher Partnership Program. This program establishes resources and infrastructure that engage K-12 science teachers in scientific research experiences. In the first implementation of this program, eleven UNO faculty mentors, drawn from several STEM disciplines, were matched with eleven OPS teachers to conduct genuine research projects in support of their teaching.
