The Mini-Patt Approach To Individualizing Instruction, Jimmy R. Jenkins, Gerald H. Krockover

Iowa Science Teachers Journal

In the past, the preparation of audio-tutorial tapes has been tedious and time-consuming. In order to produce a commercial quality audio-tutorial tape, the instructor had to outline the format of the presentation, gather the necessary materials, and prepare a rough tape. This tape was then transcribed into a script, the script was edited (usually by the instructor) and a final tape for instructional purposes was prepared from the edited script. Usually the above sequence of steps required approximately eight to ten hours, which would be spread over a two- or three-day period, with the end product being a 30-minute reel-to-reel …

A Model For Implementing Individualization In The Science Classroom, Barton Philipps

Iowa Science Teachers Journal

Teachers today find themselves in the middle of tremendous education changes and as teachers they will be expected to play an important part in implementing course revisions. Which part shall they play? Some have closed their eyes to the new directions and hope they will go away, but like the ostrich these teachers are just fooling themselves. The numbers of open classroom elementary schools are increasing and the traditional ways of presenting science in the high schools will encounter greater student resentment. It therefore behooves teachers to begin to look for a way to introduce change in their classroom. What …

Open Letter From The President, Ken Frazier

Over the past several years I have watched with special interest our appeal for increased membership from the ranks of our elementary teachers of the state. This appeal has been answered with increased numbers of elementary teachers taking active roles in the various science activities sponsored in whole or in part by the Iowa Science Teachers Section of the Iowa Academy.

What's A Kohoutek?, David Hurd

Iowa Science Teachers Journal

It was discovered in March of 1973 by Lubos Kohoutek, a German astronomer working at the Hamburg Observatory. The discovery images, on photographic plates taken during an asteroid search, did not indicate the impressive qualities of this travelling space iceberg. It was after 4 weeks of observation that the orbit of this new comet was calculated. The orbit turned out to classify Comet Kohoutek as a member of the "sun-grazers."

Proceedings of the Iowa Academy of Science

A new protoplasmodial species of the genus Licea is reported from dung of herbivorous animals. It is differentiated from all other species in the genus except one by a smooth shiny black peridium; from L. fimicola Dearness and Bisby it differs by sporangial shape and spore characters.

A Tribute To Professor Alexopoulos, Robert G. Franke

Proceedings of the Iowa Academy of Science

This issue of the Proceedings began to take form on June 17, 1973, at the University of Massachusetts when many of the former students of Professor Alexopoulos gathered to present him and Mrs. Alexopoulos with a "day of appreciation." The reading of scientific papers written by his students, the banquet that evening, and the preparation of this issue of the Proceedings which includes those papers was an honor for all of us because it provided an opportunity to express our appreciation to our warmly admired teacher. That the Board of the Iowa Academy of Science, especially the Editorial …

Age And Growth Of Shovelnose Sturgeon, Scaphirhynchus Platorynchus (Rafinesque), In The Mississippi River, Don R. Helms

Proceedings of the Iowa Academy of Science

Anterior pectoral fin rays and body measurements were collected from 110 shovelnose sturgeon captured from October 29 through November 5, 1971, in pool 13 of the Mississippi River. Fork length ranged from 7.4 to 23.7 inches and weight ranged from.06 to 2.02 lbs. The length-weight relationship was estimated as log₁₀W = -4.292 + 3.307 log₁₀FL with standard deviation for the regression coefficients ±.046 and ±.038, respectively. Condition factors (C) averaged 11.6 with a range from 9 to 17. Mean lengths at time of capture were 8.9, 13.7, 18.9 and 22.0 inches for age groups 0 through …

Sexism And The Newberry Medal, Jean Clingman Huckleberry

Graduate Research Papers

It is time now to think, time to become conscious and to delve into a sample of Newbery winners. Four Newbery books were chosen for this study in an effort to compare the earlier winners, when sexism was not such a popular issue, with two current winners to discern whether a change had taken place, if indeed a change was necessary. The two older books are Invincible Louisa by Cornelia Meigs, the 1934 winner, and Thimble Summer by Elizabeth Enright, the 1939 winner. The 1930's was chosen because it was a decade in which every Newbery book was written by …

What does it take to get a radio station on the air everyday? It takes careful organization of the records that have been listed to be played for the student's record program .... it means polishing the copy for the "research" programs that are assigned ….it means checking the teletype for the latest news and weather for a 5-minute summary ....it means searching for the correct pronunciation of the names of composers and their classical compositions ....it means preparing the board for that first button punch that signs the station on the air.

Some Temporal Factors In Visual Pattern Recognition. Ii, Lee S. Cohene, Harold P. Bechtoldt

Proceedings of the Iowa Academy of Science

Pairs of random dot patterns in which the patterns of each pair formed bigrams when superimposed were used to investigate the hypothesis that the temporal integration of visual patterns reported by Eriksen could he extended toward the longer time scale used in studies of eidetic imagery. An integration theory suggests that when the dot pattern stimuli are temporally separated, the neural trace arising from the first pattern must be combined with the second pattern for a verbal recognition to occur. However, the unexpected results of the present study indicated that a first dot pattern of 1, 3 or 5.4 sec. …

The Crinoid Genus Sygcaulocrinus From Iowa, Harrell L. Strimple

Proceedings of the Iowa Academy of Science

Attention is called to the synonomy of Ectenocrinus elongatus Thomas and Ladd, 1926, with Sygcaulocrinus typus Ulrich, 1924, both from the Ft. Atkinson Member, Maquoketa Formation (Ordovician), and to the probable bottom dwelling habitat of the species. Comparison is made with some Upper Paleozoic crinoids which are known to have been bottom dwellers. An accident in preparation of a specimen disclosed the solid base of the cup and the solid summit of the proximal columnal, both of which are illustrated.

Forest Communities In Woodman Hollow State Preserve, Iowa, David A. Niemann, Roger Q. Landers Jr.

Proceedings of the Iowa Academy of Science

The vegetation of this relatively undisturbed forest in central Iowa was sampled by a transect across a stream valley to determine species presence. The presence data were used in delineation of communities and in a computer ordination of the vegetation. Analysis revealed four distinct groupings, or communities, in the preserve: oak-hickory, prairie opening, floodplain and north-facing slope. The communities and their boundaries, determined through comparisons of species distribution diagrams, were also identified in the continuum of plots arrived at by an ordination technique. The communities showed a strong relationship to the topography of the preserve. Species composition of the communities …

Influence Of Blue-Green Algae On The Ph And Buffer Capacity Of Culture Media, Ruth B. Wildman, Barbara L. Benner, Douglas D. Held, Charles W. Schauberger

Proceedings of the Iowa Academy of Science

Three strains of the blue-green algae Anabaena cylindrica, Anacystis nidulans and Nostoc muscorum are able to adjust the pH of culture medium from stress levels (pH 4-6) to levels favorable for growth (pH 7-10). Over a period of one week, these strains increased the buffer capacity of their media with time. The pH of maximum buffer capacity after one week was very close to the pK₂ of phosphoric acid. Algae grown in a medium initially buffered with Na₂CO₃ shifted the pH of maximum buffer capacity from the pK of carbonic acid to that of phosphoric acid.

Utilization Of Educational Television In Iowa's Elementary Schools, Jane Barker

Graduate Research Papers

In today;'s fast-paced world where messages conveyed through many forms of media, television as a form of entertainment has enjoyed much popularity. It has grown in recent years as a method of instruction in the school. The success of "Sesame Street" has powerfully demonstrated the potential of instruction through entertainment.

Television can be used effectively for learning, especially if used regularly. Kelly (1964) has shown that when television is used regularly as a source of instruction in the form of lectures and demonstrations, students do as well and sometimes significantly better on tests than when it is not used regularly. …
