The Use Of Short-Count Methods On Field Collected Diatom Communities To Determine Water Quality Of Small Streams, James A. Slock

Proceedings of the Iowa Academy of Science

This study was undertaken to determine if short-count methods for calculation of diatom species diversity could be used to determine the water quality of small streams. Two small streams, located in North Central Iowa, were selected for study; one was chosen because it appeared to be in a relatively healthy condition and the other because it appeared to be highly polluted. Diatom samples were collected by direct field collection of the predominant diatom growths in each stream. Short-counts of 50, 100, 200, 500, and 1000 diatom valves were made and species diversity computed by 2 methods, the Shannon Index of …

Iowa Tornadoes: Motivators For Science Teaching, John Stanford

Iowa Science Teachers Journal

Iowa is located in the northern portion of the Midwestern "tornado belt." Students' natural interest in tornadoes and thunderstorms provide the alert teacher a ready-made introduction to science and the environment. The new paperback TORNADO -Accounts of Tornadoes in Iowa provides a wealth of information for the teacher, as well as reading material appropriate for students from upper-elementary through college.

Utilization Of Wave Energy, Walter R. Schmitt

Iowa Science Teachers Journal

When looking upon an aroused sea, many wonder how this seemingly large energy resource could be used. Inventive minds have gone to work on devices of all kinds - pumps and bellows, buoys, barges, and ramps, surface and subsurface siting, using alloys and plastics, etc. -generally based on mechanical or hydraulic principles. They would probably all work (if somebody would build them), but none thus far have been shown to do so profitably.

Acetate Peels From Iowa Carbonate Rocks, Wayne I. Anderson, Mary Hogan

Iowa Science Teachers Journal

Iowa's rock record is noted for its abundance of carbonate rocks. These carbonate rocks, limestones and dolomites, contain interesting textural features and an abundance of fossils. The fossils can often be removed from the rock matrix and studied. The fossils can also be studied in cut and polished slabs of rock or by making thin sections of the rock. Thin sections are prepared by cutting a thin slice from the rock and gluing the slice on a glass slide. The rock slice is then ground-down with abrasives to a thickness of .030 mm., covered with a coverslip, and studied with …

Elementary Science Teaching With Little Or No Equipment, Claison Groff

Iowa Science Teachers Journal

Elementary teachers seem to be ill at ease in the classroom when teaching science. Most elementary teachers tell me that they feel insecure when dealing with the laboratory aspects because they have had little training in the subject area. Most problems seem to center around activities which take time to prepare and equipment which most elementary classrooms lack or need to borrow from the Science Department. Most equipment and supplies are too expensive for any elementary curriculum to have on hand for use once or twice a year. Many elementary teachers teach strictly from the book and do not get …

A Comparison Of The Responses Of Uni Students Direct From High School, Fall Semester 1979, And Their Parents To Statements Pertaining To Selected Educational And Social Issues, Paul C. Kelso

History of Education Book Gallery

This paper summarizes the results of the student-parent survey conducted on the University of Northern Iowa during pre-orientation session for new students and their parents in June and July 1979.

The purposes of the survey were to:

1. Secure the opinions of new students and their parents regarding selected current educational and social issues.

2. Compare the opinions of the students and parents.

3. Present the findings as a part of the orientation program.

4. Utilize the opinions of the students and parents in developing future programs in the various student: services areas at the University of Northern Iowa.

An Information Processing Approach To Group Performance Of Poetry: Implications For Adaptation And Audience Research, Sandra Highnam

Dissertations and Theses @ UNI

This investigation explores the relationship between a neurological model of information processing and a group performance of poetry. It focuses upon three considerations: construction of a neurological model of information processing, application of this model to group performance of poetry, and implications for adaptation of poetry and audience research.

A neurological model of information processing is constructed which explains perception in terms of the specialized functions of the left and right hemispheres. According to this model, certain aspects of the environment (stimuli) are more efficiently processed by each hemisphere: the left dealing largely with verbal material and the right with …

Fixed Versus Random Scheduling Of Classroom Activities In A Resource Room Setting, Joanne Marie Fegley Broadston

Dissertations and Theses @ UNI

There has been a dramatic upswing in the number of resource classrooms and students in the last decade. There has also been a lack of research regarding resource students in the resource setting. While teachers have assured that regular classroom practices or methods used with other specialized populations were also appropriate for this new kind of student and setting little research has been done to either support or reject these practices or methods. The purpose of this study was to determine the effect which assigning class takes in a fixed order, rather than a random order, had on the numbers …

The Relationship Between Reading Levels And Self-Concept Of Disabled Readers, Marilyn Ann Cox

Dissertations and Theses @ UNI

It has been noted that emotional factors are an integral part of a child's success in learning to read. Research indicates that one of the most important personality factors is self-concept. Because the disabled reader has met with repeated failures his self-concept appears to be significantly affected. However, the fact that each person's self-concept is private, personal, and not directly observable makes it difficult to measure. A complication in self-concept measurement is that there have been almost as many measuring devices as there have been studies. Two types of self-concept measures are discussed in the review of literature. The purpose …

Preferences And Practices In High School Chemistry In Iowa, Robert W. Hanson

Proceedings of the Iowa Academy of Science

A simple questionnaire was sent to Iowa's 474 teachers of high school chemistry in 1978 to determine textbook preference, degree of acceptance of self-paced instruction, popularity of the modular approach, and amount of time spent in the laboratory. The responses combined with information provided by the Department of Public Instruction revealed that the traditional approach to teaching chemistry appears to predominate in Iowa and that one particular textbook is the preference of a third of the teachers.

The Ethics Of Business And Herbert Hoover’S Internationalism, Robin L. Hamilton

Dissertations and Theses @ UNI

Is it possible that someone possessed the attributes of a humanitarian and yet acted in such a way that those same characteristics were lost? Could an administrator deal with the plight of the unfortunate members of society and fail to recognize the causational factors of that plight? It would appear illogical to reason that the correct responses to the above questions could be in the affirmative, and yet the affirmative answers seemed to be applicable to the life and career of Herbert Hoover. The time-line ran from West Branch, Iowa, in 1874, ending in that same village in 1964.

Is There A Greater Role For Insects As Food?, G. R. Defoliart

Iowa Science Teachers Journal

The world food deficit has resulted in an expanded effort to find new sources of protein. With significant research efforts directed toward development of oilseed, leaf, fish and single cell concentrates, it is surprising that insects have been almost totally overlooked. They are a natural food for many kinds of animals and they are used widely as food by some human populations, especially in the tropics where they help compensate for the general deficiency in animal proteins, fats and calories. The few biochemical studies done to date indicate that insect protein is of high quality.
