The Acs-Nsta Cooperative High School Chemistry Examinations, Albert J. Judge, Charles W. Hendrickson

Iowa Science Teachers Journal

Teachers of chemistry have available an evaluative tool used extensively throughout the nation to measure the end-of-year achievement of high school chemistry students. This instrument is the ACS-NSTA Cooperative High School Chemistry Examination. The National High School Testing Program under the direction of Professor Theodore A. Ashford has made available to high school teachers a series of widely used ACS-NSTA Cooperative Chemistry Examinations. It is estimated that over a million and a half high school students have been tested since the first ACS-NSTA High School Chemistry Examination appeared in the late 1950s.

Iowa Upstep: A New Program In Science Education, Louis Gatta

Iowa Science Teachers Journal

At a time when knowledge is exponentially increasing and advances in pure science are being incorporated into an ever accelerating technological society, there exists a trend toward fewer and fewer adequately prepared science teachers. At a time when total enrollment in junior and senior high schools is reaching record breaking numbers, the enrollment in elective science courses is on the decline.

Open Letter From The Editor, Robert E. Yager

Iowa Science Teachers Journal

As we prepare copy for Volume 9 of the Iowa Science Teachers' Journal, we are reminded that this volume represents the ninth year for the Journal in its present format and as a publication of the Iowa Academy of Science. Because no appropriation was made by the state legislature during 1971 for support of the Academy, the Journal will be issued only three times during 1971- 72.

Teaching Teaching, D. J. Moffatt, A. W. Jacobs, W. K. Metcalf

Iowa Science Teachers Journal

The role of a modern Anatomy department is threefold (Metcalf, 1970): 1. To teach anatomy and its sub-disciplines, gross anatomy, neuroanatomy, microscopic anatomy and embryology, to people who wish to learn it. 2. To advance the science of anatomy-the structural basis of function. 3. To train graduate students for a future role as anatomy faculty.

A Study Of The Nsf College Science Improvement Program, David E. Drew

CGU Faculty Publications and Research

The College Science Improvement Program was launched in 1966 and has as its stated goal "... to accelerate the development of the science capabilities of predominantly undergraduate institutions and to enhance their capacity for continuing self-renewal" (National Science Foundation, 1969, p. 90). Between the program's inception and the end of fiscal year 1969, COSIP made 105 grants representing a total amount of over $18,000,000 to such institutions

It's What We Tried To Tell Them Half A Century Ago

Iowa Science Teachers Journal

Transportation Secretary Volpe made headlines last month when he urged an international agreement for tighter controls to curb oil pollution by tankers that dump oily "ballast water" at sea.

Science Through Choice, Darrell G. Phillips

Iowa Science Teachers Journal

The young lady pictured on the front cover of this issue is deeply involved in structuring her own intellect. She is certainly finding out how particular things "work," but, more importantly she is using her own mind to plan next steps, to explore possibilities and to make decisions. Such intense involvement in learning is not at all uncommon, but this particular situation is highly unique-unique because it is taking place in a science classroom in a public school!

Using A Computer In High School Chemistry, Floyd F. Sturtevant, Kenneth A. Hartman

Iowa Science Teachers Journal

The advent of the computer is having a great influence on our society and the educational system. Many public school systems have contracted with institutions and organizations for use of their computer facility in class scheduling, pupil accounting, fiscal accounting, preparation of student grades and the like. The computer has not, with the exception of some experimental situations, been widely used in the public schools as an instructional tool. The advent of the time-sharing and multi-tasking computer provides the opportunity for public schools to avail themselves of an instructional computer at a reasonable cost without employing specialized computer scientists. It …

Statisticians earned the highest median salaries ($16,900) among 313,000 scientific and technical personnel in the United States in 1970, the National Science Foundation reports. Computer scientists were second highest on the list with $16,500 and economists third with $16,300.

Helping Children Learn Earth-Space Science

Iowa Science Teachers Journal

For teachers who are looking for more ideas and background in teaching earth and space science, this new publication should provide just the lift. Helping Children Learn Earth-Space Science is a compilation of outstanding articles which have been brought together from Science and Children, 1963-1971, by William B. Matthews III, Professor of Geology at Lamar State College of Technology, Texas.

Investigative Methods For The Science Teacher, Bernard D. Hermanson

Iowa Science Teachers Journal

The basis for this research project was the idea: Why tell or lecture students about an idea or fact when, if given the appropriate information, they would be able to figure it out for themselves? This does not mean that we hand the students a text and tell them to learn about the subject on their own, nor is this "investigative" approach to be used all the time. Because of the different levels of reasoning needed for various topics, one cannot expect a student to deduce the composition of an atom as easily as he can deduce the composition of …

Paramecia Affected By Leaf Extracts, M. Bley, B. Frenchick, K. Smith

Iowa Science Teachers Journal

Leaves and needles from deciduous and coniferous trees play a major role in the formation of soil in their respective forests and thus help to determine the type of life that can successfully live there. Because of the known effects of leaf and needle litter on larger invertebrate life, earthworms, millipedes, etc., it was decided to experiment with infusions of paramecia derived from both leaves and needles to see if they were similarly affected.
