Popular Cultural Portrayals Of Those Who Do Mathematics, Carmen M. Latterell, Janelle L. Wilson

Humanistic Mathematics Network Journal

This article examines the popular cultural portrayals of mathematicians, but also anyone who does mathematics. Themes occurring in comic strips, television programs, literature, and, especially, in the movies are examined. Implications discussed include that secondary students are not going to be willing to do mathematics, if doing mathematics is not presented as a cultural activity.

Nebraska Tractor Tests

ABOUT THE TEST REPORT AND USE OF THE DATA The test data contained in this report are a tabulation of the results of a series of tests. Due to the restricted format of these pages, only a limited amount of data and not all of the tractor specifications are included. The full OECD report contains usually about 30 pages of data and specifications. The test data were obtained for each tractor under similar conditions and therefore, provide a means of comparison of performance based on a limited set of reported data. EXPLANATION OF THE TEST PROCEDURES Purpose The purpose of …

Teaching Engineering Courses With Workbooks, Yaşar Demirel

Department of Chemical and Biomolecular Engineering: News Releases

Society expects that a modem college education will turn out students who are analytical. intellectually curious, culturally aware, employable, and capable of leadership. Some important skills needed for all degree programs are problem solving, communication (written and oral), team or group work, learning and information processing, and technology. Instructors feel rewarded and satisfied when they sense that they have made a difference in the life of a student.

Flow Cytometry Used To Assess Genetic Damage In Frogs From Farm Ponds, Bartholomew L. Bly, Melinda G. Knutson, Mark B. Sandheinrich, Brian R. Gray, Dean A. Jobe

Journal of the Iowa Academy of Science: JIAS

Flow cytometry (FC) is a laboratory method used to detect genetic damage induced by environmental contaminants and other stressors in animals, including amphibians. We tested FC methods on three species of ranid frogs collected from farm ponds and natural wetlands in southeastern Minnesota. We compared FC metrics for Rana clamitans between ponds with direct exposure to agricultural contaminants and reference (unexposed) ponds. Concentrations of atrazine in water from our farm ponds ranged from 0.04 to 0.55 ppb. We found that R. clamitans from exposed ponds had DNA content similar to frogs from unexposed ponds. Pond-averaged C-values (a measure of DNA …

Move To Component Based Architectures: Introducing Microsoft's .Net Platform Into The College Classroom, Meg C. Murray

Faculty Articles

A transformation has been occurring in the architectural model for computer-based application intense software systems. This new model, software-as-a-service, will have a profound impact on the design and development of software for many years to come and as such college level computing curriculums will need to incorporate the concepts and methodologies associated with this new architecture. The platform is built upon a view of interrelated, distributed peer-level software modules and components that work in tandem to achieve specified functional goals. From Microsoft's viewpoint, migration to the new platform requires a radical shift in the software development lifecycle. It is becoming …

Water Quality Assessment: A Hands-On Approach To Environmental Education, Tracy Lynn Royse

All Graduate Projects

A water quality assessment lab manual has been created to assist secondary educators using the HACH water quality testing kits. It consists of ten chemical tests, a geological survey and a biological assessment largely based upon Washington State University's lab format and the Walla Walla County Conservation District's water study protocol. The lab manual also contains safety guidelines, a scoring rubric and an action plan research project. The environmental approach to science education used in the lab manual meets the Essential Academic Learning Requirements adopted by the Washington State Commission on Student Learning as well as the National Science Education …

Proposal For An Elemenatry Science Curriculum Outline To Help K-4 Teachers Prepare Students To Take The 5th Grade Science Wasl, Cindy D. Williams

All Graduate Projects

With a statewide pilot of the 5th grade science Washington Assessment of Student Leaming (WASL) in the spring of 2003, all elementary schools were tiying to prepare their students to meet the standards. At this time, the only resources schools had for preparation was a glimpse of the first criterion-referenced assessment, the Essential Academic Learning Requirements (EALRs), Grade level Expectations (GLEs) and a "release booklet" of sample items distributed to 5th grade science teachers. Educators knew that the best curriculum built on the previous year's knowledge which spiraled throughout the curriculum. At this time there were no curriculums designed starting …

An Advanced Mathematics Program For Middle School Teachers, D. Carothers

Journal of Mathematics and Science: Collaborative Explorations

The Conference Board of the Mathematical Sciences (CBMS), National Council of Teachers of Mathematics, and other organizations recommend twenty-one credits of mathematics coursework for prospective middle school teachers, beginning with a foundation based on mathematics for the elementary school curriculum, and followed by advanced courses directly addressing middle school mathematics. Three simultaneous factors—the emergence of the Interdisciplinary Liberal Studies Program at James Madison University, the release of CBMS guidelines, and a statewide focus on a critical shortage of qualified middle school teachers—provided an immediate audience for new upper-division courses built around the guidelines in probability/statistics, algebra, geometry, and calculus/analysis. We …

Scholarship and Professional Work - LAS

An article for Skeptic Magazine investigating the effect of science literacy on pseudoscientific belief. Authors found no significant relationship between science literacy scores and pseudoscientific belief. Students observed were significantly skeptical of psuedoscientific belief overall.

Plant Parasitic Fungi Of Ten Tallgrass Prairies Of Iowa: Distribution And Prevalence, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

During the 1980s and 1990s, collections of fungal parasites on above ground parts of prairie plants in Iowa were made throughout the growing seasons. This report presents the fungi recorded from three groups of Iowa tallgrass prairies. The western group was composed of Dinesen, Steele and Stinson Prairie State Preserves, a Loess Hills group of collecting sites in Five Ridge and Runkel Prairie State Preserves and prairies at Waubonsie State Park. 180 species of fungi were collected on 116 hosts from these prairies. A central Iowa group of prairies associated with the Des Moines Lobe landform, Anderson, Doolittle, Kalsow and …

A Comparison Of Drinking Water Contamination In Buried Slab Wells, Other Large-Diameter Wells, And Drilled Wells, Rita M. Gergely

Journal of the Iowa Academy of Science: JIAS

This study presents the results of a statewide water well survey conducted by the Iowa Department of Public Health from 1993 to 1995 to determine whether there were statistically significant differences between well water contamination in buried slab wells, other large-diameter wells, and drilled wells. Wells were sampled for total coliform bacteria, fecal coliform bacteria, nitrate, and atrazine. Staff collected water samples and completed a site survey at each well, which included an interview with the occupant or owner and actual observations of the wellhead and surrounding area.

The study included 293 buried slab wells, 287 other large-diameter wells, and …

Biomass Yield Stability In Alfalfa, Joseph G. Robins, Heathcliffe Riday, Sara J. Helland, E. Charles Brummer

Journal of the Iowa Academy of Science: JIAS

In addition to biomass production, alfalfa (Medicago sativa) cultivars also need to express yield stability across diverse environments. The objective of this experiment was to analyze the nature of biomass yield stability in ten commercial alfalfa cultivars by evaluating performance of individual genotypes. Biomass yield was measured in each of five environments across two years, and the yield stability computed for the overall cultivar mean performance and the mean performance of each of the genotypes comprising the cultivars using the genotype x environment variance statistic of Shukla and the superiority statistic of Lin and Binns'. The GxE variance of the …
