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

The Paradox, James Hungerford
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
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 …
