Summer Soil Temperatures On Algific Talus Slopes In Northeast Iowa, Tom R. Cottrell, Kyle S. Strode

Journal of the Iowa Academy of Science: JIAS

Soil temperatures at 15 cm depth were recorded on a single occasion at multiple grid points on two algific talus slopes during the summer of 1999. To represent and compare soil temperatures over a wider area, soil temperatures were measured (less intensively) at five other algific slopes and three non-algific forested slopes. Algific slopes appear to have greater variation in soil temperatures than non-algific sites. Spatial variation in algific slope soil temperatures ranged from 4-25°C. During the 10 day sample period temporal variation in air temperature at a nearby weather station had a similar range. Isotherm plots reveal a heterogeneous …

Discordant Harmonies In Fingernail Clam Populations (Musculium Transversum) Of Mississippi River Backwater Lakes, Jim Eckblad

Journal of the Iowa Academy of Science: JIAS

The populations of Musculium transversum from 8 backwater lakes have been studied over a 29-year period based upon over 440 grab samples. These lakes in Navigation Pool 9 of the Upper Mississippi River (UMR) range in size from 2 to 255 hectare surface area, mean depths from 0.2 to 0.9 meters, with mean water exchange times from 0.5 to almost 57 hours. Samples from the 1989-91 period suggested summer Muscu!ium populations had declined to about 9 percent of their mid-1970 levels. Deterministic models have attempted to explain this decline. More recent sampling suggests a substantial recovery of Musculium populations (mid-summer …

Threatened By Industry, Saved By Science: Mussel Propagation At The Fairport Biological Laboratory, James Pritchard

Journal of the Iowa Academy of Science: JIAS

During the 1890s, people on the Mississippi River exploited mussel populations to support a thriving button industry. Within a brief time, they noticed significant declines in mussel populations, and called on the U.S. Bureau of Fisheries to save the resource. This paper discusses mussel propagation studies, techniques, and activities carried on in association with the Fairport Biological Laboratory (Iowa) from about 1908 to 1932. While scientists developed sophisticated techniques and had success in mussel propagation, changing habitat conditions in the river (caused mainly by pollution and dam construction) meant limited success in rescuing mussel stocks, while the introduction of plastic …

Teacher-In-Residence Program At California State University, Chico, W. Fisher

Journal of Mathematics and Science: Collaborative Explorations

California State University, Chico has incorporated a Teacher-in-Residence program within the Department of Mathematics and Statistics. The purpose of this program is to have an elementary school teacher take a leave of absence from his or her classroom in order to work half—time in the Department of Mathematics at the University and half-time for the Chico Unified School District as a Mathematics Resource Specialist.

Active Facilitation: What Do Specialists Need To Know And How Might They Learn It?, D. Schifter, J. B. Lester

Journal of Mathematics and Science: Collaborative Explorations

Sustained, innovative professional development is now widely acknowledged as essential to the improvement of mathematics instruction in the nation’s schools. In recent years, this recognition has prompted the production of a variety of materials designed to support new teacher development programs. However, with the availability of such materials, serious concerns arise as to the kinds of knowledge required of professional development providers, often teachers who have been assigned Mathematics Specialist roles, and the means by which this knowledge is to be acquired. The authors of this paper address such questions in the context of one professional development seminar, Developing Mathematical …

Integrating Award Winning Literature Into A Constructivist Based Middle School Mathematics Curriculum, Michael Douglas Martone

All Graduate Projects

The purpose of this project was to design three independent units that integrate award winning literature and mathematics to be used in middle school mathematics classrooms. Numerous educators have been linking mathematics and literature in their classrooms. Children's literature gives students context in mathematics that can lead to an increase in students understanding of concepts. This project includes three independent units that are aligned with the national standards set forth by the National Council of Teachers of Mathematics. Suggestions for further study on the connection between literature and mathematics are discussed.
