A Philosophy For Present-Day Education, James L. Kelly
A Philosophy For Present-Day Education, James L. Kelly
Iowa Science Teachers Journal
It seems that public education is being attacked more and more concerning the lack of quality education. In part, what is being challenged are the methods of teaching children, governed by an established and practiced philosophy. Many school systems don't operate with a stated philosophy and therefore cannot implement such. Moreover, it would seem unlikely that one could find two teachers, in such a system, who would be teaching with the same philosophical objectives in mind. In short, there is no consistent "practice what you preach" format for teachers to follow in many school systems.

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

Help Keep Hawks In Hawkeye Land, Steve Duecker
Help Keep Hawks In Hawkeye Land, Steve Duecker
Iowa Science Teachers Journal
Many people have watched a hawk soar on a warm spring day. As the hawk turns lazy circles in the sky, he is riding currents of air that push him up. Not much hunting is done from this soar. Hawks are equipped with strong feet and sharp claws called talons. These are for capturing and killing their food. Their hooked beak is used to tear the food up for swallowing. Hawks have ear openings and can hear fairly well. The eyes of the hawk are about eight times more powerful than a human's and are especially built to detect movement …
Self-Pacing, Individualized Instruction: An Overview, James L. Kelly, Richard Strub
Self-Pacing, Individualized Instruction: An Overview, James L. Kelly, Richard Strub
Iowa Science Teachers Journal
During the last fifty years, education has been in a flux due to continuous technological changes and greater interaction on the societal scene. As a result, developmental education practices have been the subject of controversy. Schools have been called upon to maintain their conservative, traditional role, yet, they are expected to continue with innovative ideas which will provide a quality education for all students regardless of their academic or socio-economic level. The stability of education at the local, state and national level is dependent on the maintenance of long-established customs; whereas, the progress of an industrial society demands constant experimentation …

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.

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

Student Construction Of A Working Solar Collector, Edward Jones, David Roberts
Student Construction Of A Working Solar Collector, Edward Jones, David Roberts
Iowa Science Teachers Journal
Student constructed projects may serve as the basis for studies of the advantages and limitations of solar energy. An eighth grade science class at Miami University's McGuffey Laboratory School completed a study of solar energy with the construction of a window unit solar collector. The collector was installed in a south window of the science room in time for use and testing during the winter of 1980. The class activity developed after numerous individual projects allowed students to test variables that would be important in the design, construction and use of such a unit. Students performed a variety of individual …
Do Reading Ability And Sex Differences Make A Difference In Science Achievement?, Sharon Wadsworth, Lynn Glass
Do Reading Ability And Sex Differences Make A Difference In Science Achievement?, Sharon Wadsworth, Lynn Glass
Iowa Science Teachers Journal
Educators, parents and politicians of late have all been concerned with test scores, especially declining test scores. Much debate has taken place concerning whether, in fact, there has been a decline in the level of student performance or, rather, whether there has been a change in the population of students taking a given test. Many explanations have been tendered concerning reasons for the possible decline in test scores. This study was concerned with science scores from one Iowa high school. Specifically, this study sought to determine if there was a decline in science test scores and to determine what variables …
