A Comparison Of The Hutchings’ Low-Stress, Factor Analysis, Hand-Held Calculator, And Conventional Addition Algorithms For Speed, Accuracy, And Preference With Regular Education Students, John C. Hampel

Masters Theses

Three repeated measures experiments were conducted to determine the efficiency with which medium and low math-achieving, fourth- and fifth-grade students computed two sizes of addition problems using each of four different algorithms. The experimenter selected the conventional algorithm and the hand-held calculator because they are currently in popular use. The experimenter selected the Hutchings' low-stress and factor analysis algorithms because of their demonstrated performance enhancing characteristics and unique design features. The three written algorithms represented a design continuum that facilitated a powerful deductive analysis.

In all conditions the Hutchings' low-stress algorithm produced incrementally superior performance consistent with its unique features. …

Geological Field Guide To The Cedar Point Biological Station, Keith County, Nebraska, Robert F. Diffendal Jr., Roger K. Pabian

School of Natural Resources: Faculty Publications

This field guide was produced by staff members of the Conservation and Survey Division of the University of Nebraska originally in 1979 at the request of Dr. Brent Nickol, former Director of the Cedar Point Biological Station. It is an introduction to the geologic history and paleoecology of the Cedar Point area intended for students, staff, and other persons using the camp. This revision has been made some 15 years after the first version to reflect changes in ideas resulting from new data collected during that time.

Users of this guide should take care when studying the rock exposures described …

1992-93 Annual Report, Illinois' Investment, Illinois Mathematics And Science Academy

Annual Reports

As you read this report—the seventh annual report of the Illinois Mathematics and Science Academy—we hope you will share our pride in the continuing growth and development of Academy programs and services, for much of this growth and development was made possible by your outstanding commitment and support.

The 1992-93 year introduced a new chapter in Academy history, one characterized by expanded partnership initiatives with schools, teachers and students throughout Illinois. As a laboratory for the advancement of teaching and learning in mathematics and science, the Academy embraced an even bolder mission in 1992-93—one of transformation. Transforming teaching and learning …

Mathematics / Science Demonstration Classrooms In Iowa

Iowa Science Teachers Journal

Last fall, about 200 mathematics and science educators participated in the Governor's II Conference on Mathematics and Science Reform. The conference focused on achieving integration of math and science in Iowa by using model classrooms. Five months later, Iowa teachers, administrators and staff continue to develop model classrooms.

A New Perspective For Science Inservice: Problem Solving Demonstration Classrooms, Julie L. Wilson, Edward L. Pizzini

Iowa Science Teachers Journal

"Project: Problem Solving in the Model Classroom" was begun one year before the Governor's II Conference as a cooperative effort between the University of Iowa and a number of Iowa school districts. The Dwight D. Eisenhower funded program was intended to develop model classrooms that used problem solving with math/science, Science/Technology /Society (STS) or technology as effective classroom practice. The project has become an integration of inservice strategies, demonstration classrooms and reform initiatives that improve science education in Iowa. At the Governor's II Conference, we recognized that future model classrooms could benefit from our experience, specifically our rationale, development of …

Demonstration Classrooms: A Thematic Approach To Science/Mathematics Integration, Carl W. Bollwinkel, Barbara A. Bonnett, Rosalie J. Cochran

Iowa Science Teachers Journal

A fundamental principle of ecology is that "everything is interconnected." This observation holds true in the academic as well as the natural world; if we study an environmental issue in depth, we find that it cannot be resolved by means of any single discipline. Environmental studies transcend all disciplines so as to include the sciences, mathematics, technology, social studies, language arts and the practical and fine arts. The science component, ecology, is itself an integrating rather than a splintering science. It draws together the traditionally separate disciplines of biology, chemistry, physics and earth science. Mathematics provides a tool for quantifying …

Model Demonstration Elementary Classrooms In Northeast Iowa: The Luther College Project, Darrel Hoff, Joyce Becker, Nanette Eklund, Wendy Stevens

Iowa Science Teachers Journal

Luther College has a tradition of elementary teacher preparation stretching back to the tum of the century. It was therefore fitting that Luther College receive the only Eisenhower model demonstration program grant given to an Iowa four-year college. Built on outreaches and contacts developed by a teacher enhancement summer workshop held on the Luther Campus in 1993, the new program extends its outreach to the entire Northeast Iowa region.

Editor's Corner - Preserving Biodiversity: Notes To A Korean Grandson, Carl W. Bollwinkel

Iowa Science Teachers Journal

One of the things that makes this world such a wonderful place is the variety of living things. There are thousands and thousands kinds of plants and animals. Some are so tiny we cannot see them without a magnifying glass. Some are bigger than elephants. Some, like parrots, have bright colors. Some, like orchids, have very strange shapes. Some, like people, come in different sizes, shapes and colors and do very interesting things. There are many differences in all these living things and we call this "diversity."

Estimation Of Percent Body Fat By Hydrostatic Weighing In High Schools, Fred W. Kolkhorst

Iowa Science Teachers Journal

Concerns with fitness have increased interest in body composition and ideal body weight. Although anthropometric (e.g. skinfold) measurements can quickly determine general body composition, hydrostatic weighings are more accurate. While most exercise physiology laboratories on university campuses have a specialized tank for performing hydrostatic weighings, adequate stations can be set up in any swimming pool for a minimal initial cost. Several scientific concepts can be demonstrated during this exercise: measurement of lung volumes, determination of body density and calculation of percent body fat.

Using Science Fiction To Teach Science Fact

Iowa Science Teachers Journal

Naola Van Orden at Sacramento City College in California has her students write science fiction stories to demonstrate their understanding of various scientific concepts. While the assignments made by Van Orden and the responses she received from her students may be too advanced for lower grades, the idea can be used from the elementary level up.

Science Notes - The Future Of Eisenhower Funds

Iowa Science Teachers Journal

Many local educators may be unaware that passage of the national "GOALS 2000" legislation will have a direct and perhaps dramatic effect on the Dwight D. Eisenhower Mathematics and Science Education Program (IKE), the Department of Education's largest program for professional development. GOALS 2000 will permit the Secretary of Education to waive the regulatory and statutory requirements of the original IKE legislation when a state files an application to implement its statewide planning for education reform.
