Thinking About Thinking Skills, Alice Krueger

Iowa Science Teachers Journal

Thinking skill instruction for school-age children is a significant topic for today's educators to consider. A coalition of 27 educational groups, including the National Education Association and the Association for Supervision and Curriculum Development, has been formed to promote thinking skill instruction in the nation's classrooms (Lytle, 1986). A poll of ASCD members shows that about 90 percent want better thinking skill instruction to be a major priority in the coming year (Beyer, 1984). Educators taking the Graduate Student Examinations now have to think through a section on reasoning.

Research Opportunities For Teachers, Donald J. Perschau

Iowa Science Teachers Journal

Somewhere during undergraduate days, all students encounter a fork in the science education road. One way leads to teaching, along a path festooned with education, psychology and "general" courses. This road leads into a people oriented, less specialized and very demanding form of science activity. The other fork in that road leads toward specialization and the "publish or perish" life of a university or industrial scientist. College students who take this other fork become non-teaching scientists, researchers, authors and those who are invited to speak at symposia. They lead a different sort of professional life.

Student Research - Inhibition Of Microorganisms By Citrus Peel Oils, Patrick Teague

Iowa Science Teachers Journal

Oils of citrus peels contain a chemical which has exhibited insecticide properties. Citrus oils might also have natural antibiotic or antifungicide properties which could prove beneficial to mankind. The purpose of this project was to analyze the possible inhibition of microorganisms by oils of citrus peels. Five citrus fruit peels were tested for bacterial or fungal inhibition on Escherichia coli, Bacillus cereus and Aspergillus niger. Oils of lemon peel showed an inhibition zone on the A. niger in the first trial. In the second experiment, all of the citrus peel oils showed an inhibition zone on the A. …

A Case For Geology, Lynn A. Brant

Iowa Science Teachers Journal

Geology suffers from two enduring stereotypes. The first stereotype is that geology is "about rocks and minerals," period. It is true that the materials, the configurations of matter, studied in geology are largely rocks and minerals, but the study of geology goes much further than this simple intention. It has a lot more to say about the world in which we live than just a study of earth materials. The second stereotype concerns the reasons one should study geology. Many persons, including not a few professional geologists, regard geology's role in society as limited to the finding and producing of …

Teaching Thinking Skills: Can We? Do We?, Edward L. Pizzini

Iowa Science Teachers Journal

In virtually every journal related to education, one can find an article pertaining to "thinking skills." To say the least, the term is on the forefront in education. Likewise, its continued emergence in science education is not coincidental. After all, science is closely associated with logic and reasoning and should be a focal point for enhancing the development of the basic skills of thinking. The basic questions raised in this manuscript are "Can we and do we teach thinking skills in the science classroom?"

I Cloned A Gene With The Vector Team, Stephen Streff

Iowa Science Teachers Journal

There were no elephants with two trunks, no corn plants with four ears and no humans turned into Frankensteins, but there was evidence of recombinant DNA, transformation and cloned organisms. During the first week in August, 26 high school instructors from across the state and two college instructors received training in the laboratory skills of recombinant DNA at Drake University. The course, "A First Laboratory Course in Recombinant DNA Technology," was presented by David Micklos, the program director for the DNA Literacy Program at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, and sponsored by Pioneer Hi-Bred International …

Ultrastructure Of Extrafloral Nectaries In Aphelandra Spp. (Acanthaceae), Lenore T. Durkee

Proceedings of the Iowa Academy of Science

Light and electron microscopy was employed to study the morphology and development of the bracteal nectaries of several species of Aphelandra (Acanthaceae). Special emphasis was given to the sub-secretory cells that show striking differences in wall structure and cytoplasmic detail when compared to the cells of the adjacent secretory layer. The appearance and location of these cells in the nectary are considered in the over-all functioning of this gland.

Vegetation Communities And Flora Of Dolliver State Park, Webster County, Iowa, Cindy L. Johnson-Groh, Deborah Q. Lewis, Judy F. Shearer

Proceedings of the Iowa Academy of Science

Dolliver State Park flora includes 408 species of vascular plants, several of which are uncommon for central Iowa. Sixteen vegetation types were identified including four new vegetation types: Quercus macrocarpa type, Populus grandidentata type, Populus tremuloides type and calcareous seep type. The flora and vegetation of Dolliver are found to be similar to Ledges State Park and Woodman Hollow State Preserve. Hill prairies and savanna-like areas are much more abundant in Dolliver than these other areas along the Des Moines River.

Life History Of Elsinoe Panici, A. W. Gabel, L. H. Tiffany

Proceedings of the Iowa Academy of Science

Elsinoe panici Tiffany and Mathre is widespread on native Panicum virgatum L. in Iowa. In June Sphaceloma (imperfect stage) conidia develop from acervuli on overwintered stromata of wind-dispersed leaf litter and culms. Germ cubes penetrate between epidermal cells of young leaves, and 2 wk later tiny yellowish, subepidermal stromata are visible. Secondary conidia develop from acervuli on these stromata within 2 wk and are spread to adjacent leaves. Stromata become black, raised, shiny, ovoid-elongate patches, composed of thick-walled pseudoparenchymatous cells. Chlorosis or necrosis does not develop around the stromata. Stromata are visible on all leaves throughout the season. Acervuli, appearing …
