An Analysis Of The Influence Of Lesson Study On Preservice Secondary Mathematics Teachers' View Of Self-As Mathematics Expert, Julie Stafford

Theses and Dissertations

This research seeks to investigate the influence of lesson study on preservice secondary mathematics teachers' view of self as mathematics expert. The study acknowledges the commonly held belief that prospective mathematics teachers have that they know and understand secondary mathematics. The purpose in engaging the preservice teachers in lesson study is to dislodge this belief. In particular, this research report focuses on one preservice teacher and her experiences during lesson study. Using the data collected, the researcher reports on the baseline beliefs that the preservice teacher held toward her knowledge of secondary mathematics, her mathematical experiences during the actual lesson …

University Technology Transfer And Economic Development: Proposed Cooperative Economic Development Agreements Under The Bayh Dole Act, Clovia Hamilton

Winthrop Faculty and Staff Publications

Technology transfer enables private industry and academia to make practical use of advanced research, development, and technical expertise. Indeed, universities are a rich source of science and technology that can support local government and business development as well as economic growth. Thus, it is essential for research universities to transfer their wisdom to the public for its use and benefit. Today, universities operate in an economic climate that requires both capital and knowledge; takes advantage of government technology initiatives (namely the Bayh- Dole Act);' and serves as a catalyst for the creation of a large number of new, incubated companies. …

A Christian Perspective On Mathematics – History Of Mathematics And Study Guides, Johan Deklerk

ACMS Journal 2004

This paper addresses two questions: (1) Will a study of the history of the subject serve any purpose in promoting a Christian perspective on mathematics? (2) Can the "science in context" approach be of further help in promoting such a perspective? The author answers both positively and provides specific examples of how he has done this in his own classes.

Creationism – A Viable Philosophy Of Mathematics, Jonathan Zderad

ACMS Journal 2004

In this paper, the author addresses two classical questions of the philosophy of mathematics: What, if any, of mathematics exists in the objective sense? How do humans know that our knowledge of mathematics is correct? He argues that the Christian doctrine of God as creator provides a basis for answering these questions. He also provides a critique of eight widely discussed philosophies of mathematics.

Restoration And Monitoring Of The River Otter Population In Iowa, J. A. Pitt, W. R. Clark, R. D. Andrews, K. P. Schlarbaum, D. D. Hoffman, S. W. Pitt

Journal of the Iowa Academy of Science: JIAS

Northern river otters (Lontra canadensis) were widespread in North America at the time of European settlement. However, river otters were extirpated from most of Iowa in the early 1900s due to habitat degradation and unregulated harvest. In 1985, the Iowa Department of Natural Resources began an effort to restore the river otter population throughout the state, including a pilot study of survival to determine if establishment was feasible. Annual survival was estimated to be 86% during the pilot study. River otters dispersed an average of about 11 km from the point of release and exhibited habitat use typical for the …

Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt

Journal of the Iowa Academy of Science: JIAS

Since the early 1990s, endocrine disrupting compounds have been recognized as an important environmental threat. Male fish exposed to effluent from large, metropolitan municipal wastewater treatment facilities (WWTFs) have developed reproductive abnormalities including ovotestes and elevated levels of plasma vitellogenin (Vtg), a plasma protein typically produced by egg-laying females. In the summer of 2000, gonads and plasma Vtg concentrations were examined in feral male fathead minnows (Pimephales promelas) collected from lagoons of 11 small, rural municipal WWTFs and a reference site (a national wildlife refuge) in Iowa. Fathead minnows were captured in traps from five of the 33 lagoons (three …

Cathodoluminescence As A Means For Distinguishing Hydrothermal From Pre-Hydrothermal Quartz In Sulfide-Bearing Mineral Deposits On The Northern Fringe Of The Upper Mississippi Valley Zinc-Lead District, Ne Iowa And Sw Wisconsin, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Sulfide-bearing mineral deposits, located on the northern fringe of the Upper Mississippi Valley Zinc-Lead District, are contained in early Ordovician carbonate rocks that are extensively silicified and dolomitized. Some silica and dolomite appear to be products of the hydrothermal processes that also formed fracture-filling and cavity-lining sulfides and other cogenetic minerals; other silica and dolomite appear to result from low-temperature, pre-hydrothermal regional diagenesis. Distinguishing hydrothermal quartz (jasperoid) from pre-hydrothermal quartz (chert) solely by hand specimen and thin section petrography is difficult because these two types of mineralization are often intimately associated with each other. Polished slabs from several of these …

Salt Tolerance Of Sunflower And Lettuce In Cultivated And Uncultivated Grass Soil, Steven H. Emerman, Emily M. Kinsinger

Journal of the Iowa Academy of Science: JIAS

We tested two hypotheses: 1) whether a vegetable crop will show greater growth under a given salinity treatment in an uncultivated grass soil than a cultivated soil and 2), if so, whether the greater growth is due to the occasional presence of relatively fresh water in macropores or the interaction between salinity and hypoxia in a soil without significant macropores. A previous study suggested uptake from. macropores was significant only for crops with high root water potential (Emerman and Dawson 1997). Hence, in this study, 21 miniature crops were grown in a greenhouse, and the ratio of root dry weight …

A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee

Journal of the Iowa Academy of Science: JIAS

Biologists often need to identify destroyed turtle nests where a predator has excavated and eaten the eggs. We present a dichotomous key to the eggs and nests of Iowa's turtles based on egg or nest morphology and known range of the species. Egg and nest morphology clearly separated most nests of the families Chelydridae and Kinosternidae and many of the Emydidae. However, egg morphology must be combined with known range to distinguish wood turtles (Glyptemys insculpta) from other emydids. These factors will also separate most false map turtles (Graptemys pseudogeographica) from other species. Similarities among egg morphologies, nest morphologies, and …
