Averaging And Set-Size Effects In Selecting Groups Of Movies For A Film Festival, Irwin P. Levin, Valerie S. Hensley

Proceedings of the Iowa Academy of Science

This paper deals with the set-size effect in information processing: the study of how subjective judgments and impressions based on sets of information vary as a function of the amount of information in the set. Subjects rated each of a series of popular old movies to be used in assembling a college film festival. They then rated intact groups of movies of various size and indicated how much money should be spent for each group. Group ratings and money allocations were examined as a function of group size. Group ratings were found to increase in polarity and money allocations were …

Learning Stations: One Method Of Individualization, Douglas Harrenstein

Graduate Research Papers

This research paper will attempt to answer the question: Learning stations: How do they work? Because of the current emphasis on individualization, learning stations offer one way of approaching individualization. The concept of learning stations hinges on the premise that the teacher can make better learning opportunities for more individual types.

On The Feasibility Of Coal-Driven Power Stations, O. R. Frisch

Iowa Science Teachers Journal

The recent discovery of coal (black, fossilized plant remains) in a number of places offers an interesting alternative to the production of power from fission. Some of the places where coal has been found show indeed signs of previous exploitation by prehistoric men, who, however, probably used it for jewels and to blacken their faces at religious ceremonies. The power potentials depend on the fact that coal can be readily oxidized, with the production of a high temperature and an energy of about 0.0000001 megawatt days per gram. That is, of course, very little, but large amounts of coal (perhaps …

Seeing Sound, Sondra Waltz

Iowa Science Teachers Journal

Making sound visible is a useful activity in teaching students the concepts that sound is caused by vibrating objects and that different sounds are caused by different types of vibration. This particular activity makes it possible to see the sounds produced by observing a vibrating, metal plate. As the plate produces sound it vibrates violently in some areas and not at all in other regions. If a small amount of very fine sand or poppy seed is sprinkled on the plate as it vibrates, the seeds will move to areas where vibration is minimal and form distinct distributional patterns on …

Food From Newspaper

Iowa Science Teachers Journal

Cellulose is the most abundant organic material which can be used as a source of food, fuel and chemicals. The net world-wide production of cellulose is estimated at one hundred billion tons per year. This is approximately 150 lbs. of cellulose per day for each and every one of the earth's 3.9 billion people. The energy to produce this vast quantity of cellulose comes from the sun and is fixed by photosynthesis.

Gas Phase Hydrogen Bonding Infrared Studies Of Four Simple Alcohols, Lawrence John Anderson

Dissertations and Theses @ UNI

The purpose of this study was to develop methods for studying gas phase hydrogen bonding and to obtain evidence of the gas phase self association of methanol, ethanol, 2-propanol and 1-propanol. A gas sample transfer manifold was designed and constructed. The gas -1 8 -1 phase infrared spectra from 3050 cm to 3800 cm of methanol, ethanol, 2-propanol and 1-propanol were examined at low and saturated pressures at approximately 4o0 c. The measured integrated absorption areas of the methanol spectra were compared to areas calculated from results found in the literature. The areas were found to be in reasonable agreement …

The Iowa Academy Of Science: 1875-1975, Robert W. Hanson

Proceedings of the Iowa Academy of Science

In tracing the beginnings of the Iowa Academy of Science, Jacob Swisher acknowledged in 1930 that the meeting of the American Association for the Advancement of Science in Dubuque in 1872 probably had much to do with the formation of the first Iowa Academy in 1875. The Dubuque meeting was the first meeting of the AAAS west of the Mississippi River, and it was at that meeting that many of the charter members of the first Academy began to develop a closer association with one another. An excursion across Iowa following the AAAS meeting touched various points of scientific interest …

A Study Of The Classification Systems For Curriculum Laboratories, Maxine M. Wegner

Graduate Research Papers

The State of Iowa, through a bill reorganizing the intermediate county education systems into fifteen intermediate area education agencies providing special education, media, and auxiliary services, has mandated that the media division shall provide a professional library and curriculum laboratory for the area that it serves.

The area media center is not a new concept in Iowa as there are presently sixteen such centers in the state

that provide a variety of services to the schools in their area with a few centers providing curriculum laboratories for the teachers in their area. These sixteen centers 4 became a part of …

Cognitive Profiles Of Blind Children: A Survey Of Intra-Child Differences, Linda L. Royster

Graduate Research Papers

"Since 1900, when the first public school class was organized in Chicago, special classes for blind children have been established in most larger and intermediate-sized communities as well. At the onset, all of the instruction for the blind was conducted in special classes. Gradually, however, blind children in these classes were reassigned for part of the day to regular classes." Today, this trend has turned into a movement to fully integrate blind children into the regular classroom. Within regular classrooms, teachers recognize the existence of individual differences; therefore, instructional methods and assignments are tailored to meet the divergent needs in …

Iowa Academy Of Science Celebrates Centennial Anniversary Of Founding, Robert W. Hanson

Iowa Science Teachers Journal

April 17-19, 1975, marks the observance of an important historical event in Iowa, for it was in 1875 that Charles E. Bessey and a handful of scientists and medical men conceived the original Iowa Academy of Science. One hundred years have produced fantastic changes in life in Iowa, and the Academy of today has almost forgotten its heritage. It has grown from a small fellowship of men dedicated to furthering scientific work in Iowa to 1,400 members-a sizable cross section of the entire scientific community representing pure and applied research, conservation activity, engineering, economics and all levels of education and …

As a science teacher I know that facts are vital parts of teaching chemistry or biology, and that the better students understand chemical and biological systems the better they will understand how organisms function. But more than facts seems to be needed to teach ecology.

Trends In Secondary Science Enrollments In Iowa, Gary Downs

Iowa Science Teachers Journal

Enrollment data were collected from the district administration for the five reported years starting with the 1968-69 school year. The data for the 1973-74 school year were collected at the school level. Collection at the school level should provide a more representative data bank for the academic programs. All the science offerings were grouped into the following seven categories: biology, chemistry, earth science, enrichment science, general science, physical science, and physics. It is interesting to note that in the 1968-69 data collection only 19 different courses were reported. In the succeeding years, 25, 56, 71, 74, and 96 were reported …

A Computer Assisted Environmental Education Resource Program, Sara K. Smerud, Gary Thomas, Tim Keenan, Dale Nimrod

Iowa Science Teachers Journal

Northeast Iowa is an exceptionally beautiful and unique region. Environmental education in the schools and communities of this area is a vital factor in enabling citizens to take a reasoned approach to the conservation and management of this region. Two observations precipitated the action which resulted in the project described in this paper. The first was that the local resources were vulnerable to being utilized in a potentially harmful manner and secondly, teachers did not seem to be taking full advantage of their local resources in their classroom instruction.
