Undergraduate Elementary Education Students’ Concepts Of Light, Deborah Lynn Orr Jan 1990

Undergraduate Elementary Education Students’ Concepts Of Light, Deborah Lynn Orr

Dissertations and Theses @ UNI

The purpose of the study was to describe some ideas that future elementary school teachers have about light and shadows. Twenty-five freshmen and sophomores in elementary education were interviewed using the Interview-About-Instances technique developed by Osborne and Gilbert. Students were asked to explain specific instances of sources and non-sources of light, the distance light travels, and the role of light in vision. Students defined the word "shadow" and predicted where shadows could be in particular situations. The results of this study indicate that many students lack factual information or have misconceptions concerning light propagation. Fifty-six percent of the students in …

Visualization, Ed Harris Jan 1989

Visualization, Ed Harris

Iowa Science Teachers Journal

In pockets of deep prehistory, humans made the first marks on their world. Those marks were completely new images, images that had not existed before. The painting and tooling on stone walls recorded and attempted to explain human interaction with the world. Languages, alphabets, systems of numbers and physical structures came much later. Each new tool eventually became interconnected with the others to produce more complex means of studying, recording and building the human-world relationship. These pockets of activity moved, merged, divided or died. The accumulations of perceptions, knowledge and technology continued to mix and reconnect.

Creative Cooperation Through Competition, Gail B. Wortmann, Peggy L. Steffen, Theodore L. Buttel Jan 1989

Creative Cooperation Through Competition, Gail B. Wortmann, Peggy L. Steffen, Theodore L. Buttel

Iowa Science Teachers Journal

The competition includes a division for fourth through sixth grades and a division for seventh and eighth grades. Our district contains nine elementary schools and one junior high. With such a large district, we have over 400 contestants. The competition takes place in the afternoons of two school days, which releases teachers to help in supervision and allows students to be dismissed at the regular time. This helps ensure large attendance and avoids after-school transportation problems.

The Breakfast Food Challenge: Helping To Meet Personal Needs In The Science Classroom, Harold R. Hungerford, Kevin C. Wise Jan 1989

The Breakfast Food Challenge: Helping To Meet Personal Needs In The Science Classroom, Harold R. Hungerford, Kevin C. Wise

Iowa Science Teachers Journal

One of the four Project Synthesis goal clusters for science education focuses on meeting the personal needs of students who are maturing in a scientific/technological society. Many existing science programs fall short in this regard, particularly if teachers are seriously interested in changing learner behavior for the better. One component of learner behavior that is highly consistent with the personal needs goal cluster of Project Synthesis is helping students become more intelligent consumers in a scientific society.

Woodrow Wilson National Science Leadership Program: Princeton, 1989, Paul D. Jones Jan 1989

Woodrow Wilson National Science Leadership Program: Princeton, 1989, Paul D. Jones

Iowa Science Teachers Journal

"Gee, Dad, Princeton! Do you realize that Einstein was at Princeton?" This is what my son said as I read my acceptance letter from the Woodrow Wilson Institute. I thought of his words as I turned off the highway onto Nassau Avenue in the heart of the Princeton campus. The old ivy-covered buildings interspersed with new modern research facilities are my idea of what a college campus should look like. After finding my dorm and getting settled in, I began to explore and to learn about my colleagues. The group consisted of people from all over the United States, truly …

A Message From Your New State Science Consultant, W. Tony Heiting

Iowa Science Teachers Journal

This opportunity to introduce myself through the pages of the Iowa Science Teachers Journal causes me to feel a bit of nostalgia. Years ago, I was editor of this journal. Approximately one month ago, I filled the position of State Science Consultant, replacing Jack Gerlovich, who is now on the faculty at Drake University. For the past 12 years, I was on contract from the University of Iowa to the Iowa Energy Policy Council (now the Energy Bureau of the Department of Natural Resources).

Editor's Corner - On The Importance Of High School Biology: A Note From The Assistant Editor For Biology, Norris M. Durham Jan 1989

Editor's Corner - On The Importance Of High School Biology: A Note From The Assistant Editor For Biology, Norris M. Durham

Iowa Science Teachers Journal

Biology is life: human life, animal life, plant life, protozoan life. Its importance should never be underestimated! Why, then, are there so many students entering my university courses with no knowledge of high school biology whatsoever? It is unthinkable that a person can complete high school without having had a course in the life science.

Improving Science Teacher Preparation: Perspective On Standards, Robert L. Fisher Jan 1989

Improving Science Teacher Preparation: Perspective On Standards, Robert L. Fisher

Iowa Science Teachers Journal

They are all telling you how to educate your future teachers of science: Legislators are passing mandates; professional committees publish report after report; state bureaucrats are holding the line on regulations that have been around for years; the National Council for the Accreditation of Teacher Education (NCATE) is adopting new standards; and the guys down the hall have suddenly become experts on what you are doing to educate teachers. Too much! But, if you are a college science instructor involved with the preparation of science teachers for the K-12 schools, there are developments from the National Science Teachers Association (NSTA) …

A National Computer Conferencing Network For Science Education, Jack A. Gerlovich Jan 1989

A National Computer Conferencing Network For Science Education, Jack A. Gerlovich

Iowa Science Teachers Journal

If science educators -- curriculum planners, supervisors and teachers -- were linked by telecommunications networks, all could experience the advantages of a conference without the usual disadvantages, such as travel costs or loss of valuable work hours. And these experiences could be frequent, regular and on-going. Motivated by such possibilities, the Council of State Science Supervisors began setting up a national telecommunications network for science education in 1986. Support for the idea came in the form of a grant from the National Science Foundation, the cooperation of state and federal government agencies and equipment and technical aid from the IBM …

Plant-Parasitic Nematodes In Iowa, Don C. Norton Jan 1989

Plant-Parasitic Nematodes In Iowa, Don C. Norton

Journal of the Iowa Academy of Science: JIAS

Ninety-nine species of plant-parasitic nematodes are recorded from Iowa. Twenty-seven are new state records. Most samples were collected from around maize or from prairies or woodlands. Similarity (Sorensen's index) of species was highest for the maize-prairie habitats (0.49), compared with maize-woodlands (0. 23), or prairie-woodland (0. 3 7) habitats. Nematode communities were most diverse in prairies with a Shannon-Weiner index (H') of 2.74, compared with 1.65 and 1.07 for woodlands and maize habitats, respectively. Evenness of species (J') was 0.41, 0.78, and 0.48 for maize, prairies, and woodlands, respectively.
