Project Excel: Web-Based Scanning Electron Microscopy For K-12 Education, L. Scott Chumbley, Connie P. Hargrave, Kristen P. Constant, Brian Hand, Thomas Andre, E. Ann Thompson

Materials Science and Engineering Publications

Project ExCEL (Extended Classroom for Enhanced Learning) brings the capabilities of scanning electron microscopy (SEM) into classrooms. University and industry personnel, working together, have developed a web-based interface to allow schools to control a modern SEM. The interface allows a user control of the operating parameters of the microscope, stage movement, and chemical analysis. Such total control is not available on any other system. Since Iowa State University (ISU) pioneered the idea of remote SEM for education, researchers have learned that providing teachers access to sophisticated equipment does not ensure that it will be used. Teachers are busy, and structured ...

Exploring The Natural Connection Of Mathematical And Musical Concepts Using Mathematica, Joe Hayter, Sarah Cobb

Mathematics, Engineering and Computer Science Undergraduate Theses

Math and music share one very common property; they are both universal languages of the world. Their scientific relationship represents another powerful tie. The harmonious, unique, and enjoyable tunes we hear are surrounded by scientific and mathematical concepts that make music possible. Exploring this natural connection between math and music allows for a more complete understanding of both these subjects. By analyzing the formulas used to create musical notes, examining how to apply matrices to music, and implementing an inter-disciplinary unit of math and music into the classroom, the reader of this thesis will discover the multitude of similarities that ...


Mathematica Outside The Lab: Transferring Classroom Material Onto The World Wide Web, Rebecca Baker Apr 2002

Mathematica Outside The Lab: Transferring Classroom Material Onto The World Wide Web, Rebecca Baker

Mathematics, Engineering and Computer Science Undergraduate Theses

The Internet has greatly expanded over the last decade, yet there are few options for people wishing to create interactive Web pages that can perform computations and neatly format mathematical expressions. Many educators wish to make classroom labs and exercises available online, without hindering students with more code than necessary. In addition to educators, many companies (such as Analytic Cycling) have a need to include interactive calculators on their Web pages. However, current mathematical tools are lacking in one or more areas. Common problems with current mathematical tools include the following: • Verbose and non-intuitive code • Lack of supporting software • Little ...

Museum Educators' Workshop Study: Attracting And Retaining Teachers In Museum-Sponsored Professional Development Programs, Steven R. Rogg Mar 2002

Museum Educators' Workshop Study: Attracting And Retaining Teachers In Museum-Sponsored Professional Development Programs, Steven R. Rogg

Steven R Rogg

In preparation for the Museum Educator’s Workshop, the Planning Team saw that a necessary first step would be to honor the perspectives of Chicago Public School (CPS) teachers and principals. Changes in Illinois Teacher Recertification requirements, changes within the CPS itself, and nation-wide developments in the teaching profession suggested that a fresh look at Chicago’s professional development landscape would be necessary. Indeed, many relevant questions about the role(s) of museums in teacher professional development were raised during initial Planning Team discussions. Here are just a few examples: Which organizations are the foremost providers of professional development for ...

Animal Dissection And Evidence-Based Life-Science And Health-Professions Education, Nathan Nobis Jan 2002

Animal Dissection And Evidence-Based Life-Science And Health-Professions Education, Nathan Nobis

EDUCATION

Balcombe’s (2000, 2001) case for replacing learning methods that require pain, suffering, and death for animals with methods that do not (computer-assisted learning, three-dimensional models, videotapes, and other alternatives) can be seen as motivated by this evidentialist perspective. Balcombe provided a wealth of empirical evidence from educational studies to show that in most contexts animal dissection is not necessary—and even counterproductive—to achieve valid educational goals, especially higher order goals (concept learning and problem solving). He demonstrated that no sound defense of dissection has been given.

How Elementary School Teachers Learn To Teach Mathematics, Phyllis Schneider Kirschner Jan 2002

How Elementary School Teachers Learn To Teach Mathematics, Phyllis Schneider Kirschner

Educational Studies Dissertations

This study examines how elementary school teachers learned to teach mathematics during their pre-service education and during their first few years of teaching. The study identifies those experiences teachers found to be most significant in their development as mathematics teachers. All seven teachers in this study had been taught using procedural methods and each had to find a way to integrate conceptual mathematics education into their own understanding. The study examines the teachers' motivations for pursuing this understanding and the circumstances that provided opportunities to do so.


Investigation Of The Relationship Between Middle School Science Teachers' Knowledge And Beliefs Regarding The Coherence And Connections Among Science Concepts And Their Classroom Practices, Francis Eberle Jan 2002

Investigation Of The Relationship Between Middle School Science Teachers' Knowledge And Beliefs Regarding The Coherence And Connections Among Science Concepts And Their Classroom Practices, Francis Eberle

Educational Studies Dissertations

This phenomenological investigation used an inductive qualitative research approach with multiple instruments and processes including a survey, interviews, classroom observations, concept maps, and classroom materials for data. The results suggest that middle school science teachers' ability to teach science in a connected and coherent fashion may be tied to their mental schema for organizing science ideas, curriculum materials, and their reflections on what they are teaching and why.

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland Jan 2002

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland

Journal of the Iowa Academy of Science: JIAS

Many species of grassland birds have been shown to avoid smaller fields. The avoidance of smaller fields, however, has not been consistently reported; avoidance may occur in one study, but not in another. To examine one possible reason for these inconsistencies, we examined how landscape composition influenced the relations between occurrence or abundance and field size. The study took place during the 1998 breeding season on 44 Conservation Reserve Program (CRP) fields located in Adair, Ringgold, and Union counties. The relations between occurrence, abundance, and field size were not influenced by landscape composition for any species.

Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis Jan 2002

Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis

Journal of the Iowa Academy of Science: JIAS

Since its inception in 1984, data from the annual Iowa "Winter Bird Feeder Survey" have provided valuable information about birds that use feeders in Iowa such as spatial and temporal population trends. Using data from the 1988 and 1994 Surveys, we examined how the occurrence of bird species that use feeders was influenced by geographic location, the habitat surrounding a house, and the types of seeds offered at a house. Of the 23 species examined, the occurrence of 8 species was influenced by latitude, 22 species were influenced by the habitat surrounding the house, and 22 species were influenced by ...


Identification And Distribution Of Masked And Hayden's Shrews (Genus Sorex) In Iowa, Howard P. Whidden, Alison W. Ray, John B. Bowles Jan 2002

Identification And Distribution Of Masked And Hayden's Shrews (Genus Sorex) In Iowa, Howard P. Whidden, Alison W. Ray, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

Masked shrews (Sorex cinereus) and Hayden's shrews (S. haydeni) are both reported from Iowa, but the two species are difficult to tell apart and their relative distributions in Iowa have been unclear. We took 13 skull measurements and examined 2 qualitative features on more than 300 specimens of Sorex from Iowa. The vast majority of our specimens could be identified easily by cranial measurements, and more than half could be identified by the relative position of the maxillary plate. We found no evidence for intergradation between the two species. Masked shrews are present throughout most of Iowa, whereas Hayden ...


Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson Jan 2002

Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson

Journal of the Iowa Academy of Science: JIAS

Gray leaf spot disease, caused by Cercospora zeae-maydis Tehon and Daniels, has become a significant disease in Iowa corn (Zea mays L.) production. Incidence of gray leaf spot has increased with the increased use of conservation tillage practices. The inheritance of resistance to gray leaf spot was studied via use of generation mean analyses for five crosses and via use of 100 S1 progenies developed from an F2 population. Experiments were conducted at two locations that included either natural or artificial inoculation with C. zeae-maydis spores. Additive and dominance effects were significant in nearly all instances. Heritability for ...


Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold Jan 2002

Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Switchgrass (Panicum virgatum L.) is a native perennial prairie grass that is now cultivated as a forage crop and a biomass crop for renewable energy. Biomass yields of switchgrass in southern Iowa have recently dropped significantly in some fields and the reduction has been attributed to disease. A disease survey was conducted in 1999 to assess the prevalence of major diseases in Chariton Valley switchgrass production. There were disease symptoms present on switchgrass plants in each field and thirteen fungal species were identified from leaf, stem, and root samples. Two pathogenic fungi, Tilletia maclaganii and Colletotrichum graminicola, were present in ...


Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves Jan 2002

Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves

Journal of the Iowa Academy of Science: JIAS

Pisoids (concentrically laminated carbonate grains, > 2 mm in diameter) are abundant in the upper Humboldt Oolite Member of the Gilmore City Formation (Mississippian). Their cortices are isopachous and nuclei include both intraclasts and fragments of preexisting

pisoids. They occur both as floating grams m a fine grainstone matrix and concentrated at the bases of distinct layers that may be crudely graded beds. Sorting characteristics and the presence of broken and abraded pisoids suggest not only their origin as primary free grams, but also storm influence in the deposition of local pisolite layers. Regionally, the upper Humboldt Oolite is characterized by ...
