The Development Of Instruments For Assessment Of Instructional Practices In Standards-Based Teaching, C. L. Wainwright, L. Flick, P. Morrell

Journal of Mathematics and Science: Collaborative Explorations

We provide a description and rationale for the development of two instruments: 1) a classroom observation protocol; and, 2) a teacher interview protocol—designed to document the impact of reform-based professional development with undergraduate mathematics and science faculty, and its impact on the resultant preparation of teachers. Constructed upon review of the research on teaching and standards documents in mathematics and science, these instruments form the basis for data collection in a three-year longitudinal study of teaching practice among early career teachers as well as undergraduate college faculty. In addition, we suggest further applications of the observation protocol beyond the original …

Journal of Mathematics and Science: Collaborative Explorations

As one part of a multifaceted evaluation of the Oregon Collaborative for Excellence in the Preparation of Teachers (OCEPT), a case study approach was used to enable a deeper understanding of how a diverse group of six institutions attempted to achieve OCEPT goals and to learn more about factors that facilitated or hindered their efforts. Multiple sources of data were used, with heavy reliance on a series of on-site interviews. The analytical framework included a "depth" and "pervasiveness" typology of institutional change and a view of change as encompassing "meaning," "organization," and "effects." While goals and accomplishment levels, as well …

The Perfect Perspective: A Mathematical Analysis Of Perspective Using Tools Available To Middle School Students, W. Griffin Jan 2003

The Perfect Perspective: A Mathematical Analysis Of Perspective Using Tools Available To Middle School Students, W. Griffin

Journal of Mathematics and Science: Collaborative Explorations

This paper examines the basic properties of perspective drawings, the history of perspective drawings, and the basic mathematics of perspective. Using a side view and a top view of a three-dimensional projection, similar triangles can be used to find distances from the axes and vanishing point in a projection. By breaking the three-dimensional projection into two, two-dimensional planes, one can recreate projections based on actual figures, or create placements of figures in real space based on a projection. Using this method, one 'can change a projection based on the changing position of the vanishing point. This simple approach to perspective …

Visualizing Basic Nuclear Reactions, D. Allen, M. T. Oliver-Hoyo Jan 2003

Visualizing Basic Nuclear Reactions, D. Allen, M. T. Oliver-Hoyo

Journal of Mathematics and Science: Collaborative Explorations

There are few instructional tools available to teach basic nuclear reactions to beginning students. The activity described in this paper can be used to help students visualize and write basic nuclear reactions such as alpha, beta, and positron decay, as well as electron capture. These reactions are represented using the technology of thermochromic paints, which either change color or turn colorless depending upon the temperature. By using a special thermochromic paint that turns colorless upon heating, students are able to visualize nuclear interactions. For instance, when positron decay occurs, the object depicting a proton will "decay" into a neutron by …

A Framework For Reproductive Models Of Mourning Doves, David L. Otis Jan 2003

A Framework For Reproductive Models Of Mourning Doves, David L. Otis

Journal of the Iowa Academy of Science: JIAS

Population models can be used to aid in development and evaluation of harvest management strategies for game species. No current models are available for the Mourning Dove (Zenaida macroura), which is considered a migratory game bird in 37 states. A predictive model for annual reproduction is a necessary component of such a model. I used a simple construct based on parameters of the Mourning Dove breeding cycle to develop probability distributions of annual per capita reproduction for each of five geographical regions in the U.S. Confidence intervals for model predictions included average estimates from published studies in all regions except …

An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts Jan 2003

An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts

Journal of the Iowa Academy of Science: JIAS

Water quality and benthic invertebrates in the Ensign Hollow watershed, southwestern Clayton County and southeastern Fayette County, Iowa, were monitored from 2000 to 2001. Measurements of physical and chemical parameters of water quality, as well as analysis of benthic invertebrates, all indicated that streams of the Ensign Hollow watershed were exposed to slight organic pollution. Furthermore, the greatest threat to this watershed appeared to be sedimentation introduced through runoff.

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 Jan 2003

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 Jan 2003

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 …

Recent Observations Of The Distribution And Status Of Freckled Madtom And First Record Of Spotted Gar In Iowa, Melvin C. Bowler

Journal of the Iowa Academy of Science: JIAS

The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. In this paper, I describe recent collections of freckled mad tom (Noturus nocturnus) and spotted gar (Lepisosteus oculatus) from the Upper Mississippi. River (UMR). Six specimens of N. nocturnus were collected from Pool 13 of the UMR in 2001. Although the first documented specimens of N. nocturnus in Iowa were collected in the English River in 1984, few collections have been made throughout the …
