Dynamic Web Tools For Trigonometry, Steven J. Wilson Jan 2008

Dynamic Web Tools For Trigonometry, Steven J. Wilson

Innovations in Math Technology

In the last 20 years, computer technology having mathematical capability has been developed, improved, and become widely available, but textbook presentations are still largely free of any discussion that might require technology. Technology could be used in mathematical instruction for student drill and practice, for instructor demonstrations that promote conceptual understanding, or for the exploration of mathematical ideas, but software is often designed to be pedagogically generic, leaving its use to the creativity of the instructor. Technological solutions for local machines can be quite extensive, but cost and time constraints then limit availability for student use. The internet has the …

Expanding The Database Curriculum, Meg Murray, Mario Guimaraes Jan 2008

Expanding The Database Curriculum, Meg Murray, Mario Guimaraes

Faculty Articles

As database concepts and technologies continue to evolve there exists a need to expand the topics included in database curricula. This is challenging given the restraints on the number of courses that can be included in a typical CS or IS program. While a set of commonly identified core concepts and principles exists, there is little consensus on what supplemental materials should be included in database courses. Through an NSF proof-of-concept grant, we designed and developed courseware incorporating the use of animations to deepen and enrich standard presentations of core database concepts and to complement database teachings as found in …

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major Jan 2008

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major

Journal of the Iowa Academy of Science: JIAS

Over one hundred and fifty years of Euro-American settlement has dramatically altered Midwestern landscapes, resulting in the widespread conversion of native habitat. Numerous opportunities to conduct ecological restoration exist within the Midwest, with the potential to increase habitat and landscape heterogeneity, secure critical ecosystem services, and provide opportunities for research and education. Site history is an important consideration for most restoration projects, and multiple sources of historical data may be required to unravel the complicated history of intensively used Midwestern landscapes. The collection of baseline data is another significant component of most restoration projects, allowing for an evaluation of community …

Pre-Settlement Vegetation At Casey's Paha State Preserve, Iowa, Reid J. Leichty, Steven H. Emerman, Lyndon R. Hawkins, Michael J. Tiano Jan 2008

Pre-Settlement Vegetation At Casey's Paha State Preserve, Iowa, Reid J. Leichty, Steven H. Emerman, Lyndon R. Hawkins, Michael J. Tiano

Journal of the Iowa Academy of Science: JIAS

Paha are loess-capped ridges standing 10-30 m above the surrounding plain of the Iowan Surface. Although Iowa was almost entirely covered with prairie and wetlands just prior to Euro-American settlement, the paha are believed to have been forested based on soil types and on early vegetation maps. The objective of this study was to find evidence that paha were forested by measuring the δ13C value of humin, the fraction of soil organic matter that is insoluble in acid and base. Previous work has shown that humin retains the δ13C signature of vegetation on a 1000-year time scale, as opposed to …
