Stimulating Interest In Iowa Secondary School Science, Jack Gerlovich, Joe Moore Jan 1979

Stimulating Interest In Iowa Secondary School Science, Jack Gerlovich, Joe Moore

Iowa Science Teachers Journal

America, today, is a highly technological society, based heavily upon knowledge of scientific concepts and principles. Without knowledge in basic science, and its processes, living with and understanding technology cannot be accomplished. More specifically, alienation of the lay public from the scientific community and scientific endeavors may result.

A Classroom Savonius Windmill, William G. Hoffman Jan 1979

A Classroom Savonius Windmill, William G. Hoffman

Iowa Science Teachers Journal

The Savonius or S-rotor windmill was introduced to the United States in 1924. The powershaft is located in the vertical plane rather than horizontally as in the traditional bladed Stuart windmill. This has several benefits. The windmill does not need a wind direction seeking vane since it doesn't matter from which direction the wind is blowing. Also, power is available at the base of the mill rather than at the top of the tower. The Savonius mill is also less easily damaged by high winds than the traditional windmill.

Building Rapport And Changing Attitudes, Owen Primavera Jan 1979

Building Rapport And Changing Attitudes, Owen Primavera

Iowa Science Teachers Journal

During the past few years there seems to be a growing apathy on the part of high school students towards education. It seems that many are weaker in the basic skills of reading, writing and mathematics and could care less about their progress. Why do students feel this way about education and what can educators do to improve the situation?

What Is The Universe, And Why Is It Doing These Strange Things?, George L. Murphy

Iowa Science Teachers Journal

1979 marks the fiftieth anniversary of a major advance in man's attempt to understand the overall structure of the physical universe. It was in 1929 that Hubble announced his discovery of the expansion of the universe. Ever since that time, astronomers have been finding evidence that the entire universe has been evolving, and have been attempting to adjust their view of the world accordingly.

Society, Science, And The Scientific Enterprise, Henry Veldhuis

Iowa Science Teachers Journal

Numerous developments in science and technology have moved man to the interfaces between science and government, science and religion, science and economics, and others. The necessity of functioning along these interfaces suggests that science education should include a commitment to the development of the scientific literacy necessary to understand the relationships between science and society.

The Need For A Philosophical Approach In The Teaching Of Science, Everett F. Morris Jan 1979

The Need For A Philosophical Approach In The Teaching Of Science, Everett F. Morris

Iowa Science Teachers Journal

In his paper, Slock (1977) commented upon a different view of what science is and how it operates. It has been my experience that prospective secondary science teachers are extremely deficient in this area. Perhaps, it is not a different view that is needed as much as a definite viewpoint that is needed.

Iowa Basic Skills Test, William Coffman

Iowa Science Teachers Journal

'"As a professional in this business of testmaking, I am much more aware of the limitations of testing than most laymen. Achievement tests such as ours are designed as tools to help teachers do their jobs. Scores from them cannot be used as final judgments on anything - not children, not teachers, not schools and certainly not American education in general."
