The Comparative Effects Of Individualized And Group Instruction In Bscs Biology On The Ability Of Students To Think Critically, Harry F. Fulton Jan 1971

The Comparative Effects Of Individualized And Group Instruction In Bscs Biology On The Ability Of Students To Think Critically, Harry F. Fulton

Iowa Science Teachers Journal

Research in the area of critical thinking ability many times involves the use of the Watson and Glaser Critical Thinking Appraisal (WGCTA). These abilities involve inference or drawing conclusions from facts or premises, recognition of assumptions or hypotheses, deduction or working from basic premises to conclusions, interpretation of data to derive or explain its meaning, and the evaluation of arguments or evidence. The items on this instrument are not specifically limited to science. As a result, when researching the effect of an instructional procedure in science, the teachers and all other subjects the students are exposed to need to be …

Conrad E. Ronneberg, professor of chemistry at Dennison University, Granville, Ohio, states in the June issue of Chemical and Engineering News that the first generation of NSF-sponsored texts such as CEA chemistry, CHEM Study chemistry, and PSSC physics, as well as BSCS biology, are totally inadequate and will probably be ignored by the new generation of science teachers.

The Acs-Nsta Cooperative High School Chemistry Examinations, Albert J. Judge, Charles W. Hendrickson Jan 1971

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.


Using A Computer In High School Chemistry, Floyd F. Sturtevant, Kennth A. Hartman Jan 1971

Using A Computer In High School Chemistry, Floyd F. Sturtevant, Kennth 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 …

Anatomy: Its Role Today And In The Future, W. K. Metcalf

Iowa Science Teachers Journal

Modern anatomy can be divided into three stages. The first stage, the dawn of modern anatomy, came in the late 15th and early 16th centuries, largely as a result of the work of two men, Leonardo da Vinci and Vesalius.


Investigative Methods For The Science Teacher, Bernard D. Hermanson Jan 1971

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.

How We Raise Paramecium, Easily, In Large Numbers, Eugene C. Bovee, Sandra C. Thompson, Mercedes L. Acuña

Iowa Science Teachers Journal

We use more Paramecium spp. in our Physiological Protozoology course at the University of Kansas than any other cells, and use them in great numbers each week, so that we wish to avoid the cost of buying them commercially. Therefore, we raise our own cultures. For over twenty years the senior author has used the easy method described here to raise large numbers of Paramecium aurelia, P. cauclatum, or P. multimicronucleatum, with consistent success.
