Nsta's Position On Inclusion Of Nonscience Theories In Science Instruction Jan 1981

Nsta's Position On Inclusion Of Nonscience Theories In Science Instruction

Iowa Science Teachers Journal

Throughout recorded history, man has been vitally concerned in finding out all that he can about his universe. He has explored it in many ways, raised questions about it, designed methods by which he could increase and organize his knowledge, and developed systems to aid him in understanding and explaining his origin, and nature, and his place in the universe. Among these systems are philosophy, religion, folklore, the arts, and science.

Some Ethical Considerations Concerning The Use Of Live Animals In Biology Experiments, David F. Treagust Jan 1981

Some Ethical Considerations Concerning The Use Of Live Animals In Biology Experiments, David F. Treagust

Iowa Science Teachers Journal

As biology teachers we are continually faced with decisions regarding the use of experiments in order to identify, investigate, clarify or illustrate a particular concept or concepts. If an experiment is to be performed we frequently have to decide whether to use live animals, preserved animal specimens, preserved animal organs, fresh animal organs (from, say, the butcher), tissue cultures, audio-visual simulations or even class members as the subjects. Many students, and indeed many teachers, have been reticent about their acceptance of experimenting with live, or freshly killed animals; frequently the issue is settled by reference to such work being in …

Statement Of The Position Of The Iowa Academy Of Science On The Status Of Creationism As A Scientific Explanation Of Natural Phenomena Jan 1981

Statement Of The Position Of The Iowa Academy Of Science On The Status Of Creationism As A Scientific Explanation Of Natural Phenomena

Iowa Science Teachers Journal

Current attempts to introduce 'scientific creationism' into the science classroom are strongly opposed by the Iowa Academy of Science on the grounds that creationism when called 'scientific' is a religious doctrine posed as science. It is contrary to the nature of science to propose supernatural explanations of natural events or their origins. With its appeal to the supernatural, creationism is outside the realm of science.


A Tool For Assessing, Implementing, And Evaluating Science Curriculum (K-12) For Iowa Schools, Jack Gerlovich, Gary Downs, George Magrane Jan 1981

A Tool For Assessing, Implementing, And Evaluating Science Curriculum (K-12) For Iowa Schools, Jack Gerlovich, Gary Downs, George Magrane

Iowa Science Teachers Journal

In the fall of 1977 the Iowa Department of Public Instruction (DPI) began to receive many requests for assistance in developing coordinated science programs. Local schools faced with aging science materials, economic constraints, increasing pressure from publishing companies, and decreasing student reading and computing skills needed guidelines for assessing, implementing and evaluating their science curriculum. The purpose of this tool is to provide such assistance.

A Method Of Evaluating Computer Programs For High School Physics, David Broadwater Jan 1981

A Method Of Evaluating Computer Programs For High School Physics, David Broadwater

Iowa Science Teachers Journal

Many high schools have access to computer terminals. Such terminals are of limited value if the computer library is not stocked with programs that are integrated into the educational program of the school. There is a need for the evaluation of computer programs with respect to their applicability to various levels of instruction. In this paper, a method of evaluating computer programs for high school physics is outlined.

Spotlighting Excellence, David Mccalley

Iowa Science Teachers Journal

Six Iowa teachers were honored by the Iowa Academy of Science during the annual meeting held at Coe College in Cedar Rapids last spring. They had been nominated by either administrators or by fellow teachers and selected by committees working with the director of the Academy's Excellence in Science Teaching Awards program. This issue will spotlight the biology and chemistry recipients. In subsequent issues, the earth science and elementary science recipients and the junior high science and physics recipients will be spotlighted.


The Paradox, James Hungerford Jan 1981

The Paradox, James Hungerford

Iowa Science Teachers Journal

Recent surveys indicate that many young adults blame science and technology for most of society's problems. On the other hand, an even larger number trust that science and technology will solve these same problems. Their expectations are for spectacular achievements from science and technology. Such expectations often stem from an unawareness of the fundamental nature and limitations of scientific inquiry.

The Natural Forest Communities Of Iowa: A Resource In Trouble, Gary Hightshoe Jan 1981

The Natural Forest Communities Of Iowa: A Resource In Trouble, Gary Hightshoe

Iowa Science Teachers Journal

Based on the original United States Land Office survey, it has been estimated that 18 percent of the total state land area was once covered by forest. Today, less than 4 percent of the Iowa landscape remains in forest. In essence, Iowa's forest lands have a value underrated and misunderstood by most of its citizens. Threatened with exhaustion of our natural forest heritage, it is imperative that the citizens of this state awaken at last to the necessity of protecting what is left. The appreciation, conservation, restoration and wise management of our remaining forest resource must play a critical role …

Iowa Science Teachers Journal

Most girls have intercourse before marriage and 96 percent of girls are sexually active before they seek contraceptive information. One girl in 10 is a mother before her 18th birthday, and the death rate of babies born to mothers under 15 years of age is more than twice the rate for babies born to mothers ages 20-24.


A Laboratory Excercise In Gas Chromatography For High School Students, Bernard Hermanson Jan 1981

A Laboratory Excercise In Gas Chromatography For High School Students, Bernard Hermanson

Iowa Science Teachers Journal

Gas chromatography is a sophisticated tool for the isolation, identification and quantification of chemical compounds. The purpose of this exercise is to introduce the principles of gas chromatography to first year chemistry students. For the exercise, students inject their own chemical samples, estimate the purity of these samples by counting the number of peaks on a print out, measure retention times for the materials observed, and compare the "r" values to those of known substances.

Comparison Of Perceptions Of Major Problems In Science Education, Jack Gerlovich, Robert Yager Jan 1981

Comparison Of Perceptions Of Major Problems In Science Education, Jack Gerlovich, Robert Yager

Iowa Science Teachers Journal

The National Science Foundation has stimulated much thought, analysis and assessment concerning the discipline of science education. The three status studies of K-12 science education have attracted national attention and study (Helgeson, 1978; Stake & Easley, 1978; Weiss, 1978). Nine professional groups have had committees analyze the results of these studies from the perspective of their respective memberships. The National Science Foundation also awarded another large research grant to the University of Colorado called Project Synthesis. This project, under the direction of Norris Harms, has attempted to synthesize the status study reports and the recent data from the National Assessment …
