A Survey Of Physics Textbooks Used In Iowa Secondary Schools (Preliminary Report), Jerry Schmidt

Iowa Science Teachers Journal

On December 5, 1969, 475 questionnaires were mailed to the public high school physics teachers of Iowa concerning the basic physics textbook(s) used in the classes they teach and the extent to which students are encouraged to answer the questions contained in the textbook(s). The questionnaire was a preliminary step of a doctoral dissertation which the author is presently working on at the University of Arkansas.

The Determination Of Stability Constants For Some Metal Chelates Of O-Phenylene-Dinitrilo-Tetraacetic Acid, Charles E. Faraci

Dissertations and Theses @ UNI

The chelating agent, o-phenylene-dinitrilo-tetraacetic acid, has been synthesized, by a method previously reported, and characterized. The formation constants for the reactions between a group of divalent metal ions and the chelon, o-phenylene-dinitrilo-tetraacetic acid, have been determined potentiometrically with a mercury electrode. The stability constants for the metal ions Hg2+, Mg2+, Mn2+, Zn2+, Co2+, Cd2+, and Pb2+ were determined. Log K values of 18.6, 7.2, 11.8, 13.3, 13.4, 13.7, and 14.1, respectively, were found at an ionic strength of 0.1 and 25°C. These stability constants were compared to those of ethylene-dinitrilo-tetraacetic acid chelate. Some of the effects of ligand structure on …

The Static And Dynamic Balance Of Rotating Mechanisms In The Automobile, Joel E. Tjelmeland

Graduate Research Papers

What are the physics and mechanics involved in the static and dynamic balance of rotating mechanisms in the automobile? To what degree is balance necessary in the various mechanisms? What machines are available for balancing the various mechanisms? What are the skills involved in the balance of these mechanisms? How can the materials available best be organized into a unit which can be used in the industrial arts power and automotive programs?

A Comparison Of The Attainment Of The Common Objectives Of The Cba, Shems, And Modern Chemistry Courses As Reflected In Student Performance On Various Objective Measures, Verne A. Troxel

Iowa Science Teachers Journal

In the February, 1968, Iowa Science Teachers' Journal the writer outlined a study in which students in Iowa and Illinois who were utilizing the CBA, CHEMS, and Modern Chemistry (MC) chemistry materials were to be studied to determine if these courses were meeting their common objectives equally.

A Study In Philosophy And Goals Of Science Education, Dale Bunsen

Iowa Science Teachers Journal

An inquiry into the philosophical area of any human endeavor results in the framing of "why" questions. Why study science at all?, naturally becomes one of these questions which has great relevance to the field of science education. "How" and "what" questions generally use up most of the science educator's time and efforts. This is not an attempt to negate the importance of "how" and "what" questions (they are the stuff of science); rather, it is an attempt to determine what the case for science is in our educational process.

Concerns Of The Articulation Committee, R. J. Vanden Branden, Robert Franke

Iowa Science Teachers Journal

Communications between the various educational institutions in Iowa is and should be the primary need which is satisfied by Articulation Committee activity. A panel, composed of Paul Tweeton of the State Department of Public Instruction, Robert Franke, and Tom Hendricksen representing two-year and four-year colleges, respectively, presented various views related to better communications and other concerns of articulation. The panel discussion was designed to provide an opportunity for dissemination of information by the panel and reception of ideas and suggestions from the audience.

Science For Students Today And Tomorrow, Robert E. Yager

Iowa Science Teachers Journal

Teaching science as a body of peculiar knowledge which exists for students to learn is still a common approach in American secondary schools. This is true today even with the so-called "new" science programs and their added impetus to the idea of teaching and emphasizing the processes of science in addition to the traditional content of a given discipline. The last ten years have seen great advances. However, much more is needed before we can talk of science in in our schools that is relevant for students both presently and in the future. We have too often accepted new ideas …

The Imbalance Of Nature, Chalmer J. Roy

Iowa Science Teachers Journal

On this fantastically dynamic planet, what can be the meaning of the balance of nature? The dynamics of the atmosphere, of the oceans, and of the solid earth show no signs of reaching an equilibrium, a condition of no change. Nature does not obey laws. The so-called laws of nature are human constructs, designed to explain observed relationships and phenomena.
