From The Editor's Desk

Iowa Science Teachers Journal

A recent study by the U.S. House-Senate Joint Economic Committee indicates that solar energy will be Iowa's cheapest way to warm homes and heat water by 1985, if Congress removes the federal price limits on natural gas.

The ISTJ Advisory Board is pleased to announce the selection of an Associate Editor in Chemistry Education. Don Murphy, of Hoover High School in Des Moines, has been selected and has accepted the position.

Large-Scale Industrial Applications Of Solar Energy, W. C. Dickinson

Iowa Science Teachers Journal

Research on solar energy sponsored by the U.S. Research and Development Administration (ERDA), at the Lawrence Livermore Laboratory, has concentrated on finding and developing techniques that can be made economically competitive with fossil fuels and can be applied by industry on a large scale. The difficulty lies in making solar energy competitive, not in identifying large-scale application. Table 1 suggests the widespread need for large-scale applications.

Can A College Level Biology Course For Majors Be Educationally Accountable?, Betty D. Allamong, Jon R. Hendrix

Iowa Science Teachers Journal

Have we, as educators, reached a point in our society where "Truth in Learning" has become as important as "Truth in Lending'? We have seen government agencies mandate controls over banks, as well as auto-mechanics, to become more accountable for their services. Now, it seems that these same controls are to be levied on those in the educational systems of this nation as well.

Parsimonious Education, Darrell D. Young

Iowa Science Teachers Journal

In science, the Law of Parsimony or Occam's Razor, is a statement of economy; it expresses the view that the simplest, adequate explanation of data is preferable to a more complex interpretation of equal adequacy. The Law of Parsimony may be applied to the area of education as well. It should be the ultimate goal of education to provide the simplest, adequate explanation in communicating to parents and students phenomenon occurring in the classroom.

Purebred?, Wilmer J. Miller

Iowa Science Teachers Journal

A notion of "purity" and connotations of cleanliness, neatness, stability, uniformity, worthiness and admirable values click through our mental processes. After all, that's what we learn in biology, especially the genetic section, don't we? Well, maybe it's colored a bit by the horticulturalists' and stock breeders' influence, and dog and cat fanciers who want pedigree papers and conformity to some arbitrary standard. Poultry and small pet fanciers have about the same attitude, but rely less on papers. But "purebred" is jargon--at worst meaningless in the context of conflicting usages, and contemptuous in use by a more sophisticated group--breeders or teachers …

More Snow Jobs, Paul Joslin

Iowa Science Teachers Journal

On the first day of snow, when the attention of children is obviously distracted from normal classroom procedures, have them bundle up and go outside. Once outside, have the students follow you in a line and form a circular path. You can then use the circle formed in the snow, to teach or review concepts associated with motion, time, direction, fractions and geometry.

Iowa Science Teachers Journal

The lead article in this issue suggests that, in the near future, computer outlets may be available in many more schools in Iowa. The utilization of computers in science classrooms has been well documented. The different ways that computers can be used in science classrooms are limited only by the creative imagination of science teachers. Computers are even being used to make out examinations.
