A Consideration Of Student Understanding Of Science In Two Approaches To Bscs Biology, Harry F. Fulton
A Consideration Of Student Understanding Of Science In Two Approaches To Bscs Biology, Harry F. Fulton
Iowa Science Teachers Journal
The understanding of science by students is considered by science educators to be a worthwhile goal in the teaching of science. Attempts have been made to achieve this goal in the various curricula that have been developed, and the Biological Sciences Curriculum Study is one of these curricula. Several studies have been attempted to measure the understanding of science as a student outcome in a particular course such as BSCS Biology. In most studies the Test On Understanding Science (TOUS) (1) was the most common instrument used.
Batteries And Bulbs With An Average Class Of Ninth Graders, Richard D. Mcvey
Batteries And Bulbs With An Average Class Of Ninth Graders, Richard D. Mcvey
Iowa Science Teachers Journal
During the fall semester of 1969 I had occasion to try some elementary science units with a low group of ninth graders. Of the units tried, the E.S.S. "Batteries and Bulbs" had such interesting results that it instilled in me the idea of trying the unit with my regular ninth grade class.

A False Sense Of "Discovery", Darrell G. Phillips
A False Sense Of "Discovery", Darrell G. Phillips
Iowa Science Teachers Journal
Within the past few years the terms "discovery" and "inquiry" have come into vogue in educational circles. These terms, and those of similar connotation, are found in science curriculum programs, magazine and journal articles, and papers presented at professional meetings. It has also become apparent that certain textbook publishers are extremely sensitive to the "in" terms; one finds that such words have been carefully inserted into the introduction or preface of some outdated science textbooks.
Study Of Science Facilities
Iowa Science Teachers Journal
The National Science Teachers Association is embarking on a nationwide study of facilities for the teaching of science at the secondary school level. The study will cover in-school facilities-laboratories, classrooms, and special-purpose rooms, such as greenhouses and planetariums-and facilities outside the school, such as outdoor education centers that are used for science programs.
The Oregon Science Teacher
Iowa Science Teachers Journal
The May, 1970, issue of TOST will be devoted to science humor, and will feature in excess of a hundred 'bits' of the bizarre, witty, irreverent, burlesqued, parodied, and off-beat side of science.

Science Tomorrow, Robert S. Hansen
Science Tomorrow, Robert S. Hansen
Iowa Science Teachers Journal
A few years ago the rate of production of scientists and (not too surprisingly) the rate of production of scientific articles was doubling every ten years. Really new science was coming out at a tremendous rate, generating major new areas such as solid state physics, molecular biology, radio-astronomy, and major breakthroughs such as the cracking of the genetic code, the discoveries of the transistor effect, of pulsars, and quasars, of techniques of stereospecific syntheses, of ultrasensitive methods of compound detection, identification, analysis, and structure determination, and of new fundamental particles in profusion.
How Much Does It Cost To Synthesize A Gene?
How Much Does It Cost To Synthesize A Gene?

Open Letter To Science Teachers: Before You Lock The Door, Delma E. Harding
Open Letter To Science Teachers: Before You Lock The Door, Delma E. Harding
Iowa Science Teachers Journal
Before closing textbooks and locking classroom doors for the summer, check on several things to help make your teaching more coordinated and meaningful when fall comes. Make out a tentative schedule for next year's classes. Decide what units to teach and approximately what length each is to be. Include a list of materials you plan to use for each unit. This means chemicals, slides, demonstrations, experiments, models, audiovisual aids, tape recordings, glassware, and anything else you expect to use. Have everything ordered or available for use, so there are no disappointments or holdups when you start teaching again.
Innovation In Science Education In Australia, Richard P. Tisher
Innovation In Science Education In Australia, Richard P. Tisher
Iowa Science Teachers Journal
There are many similarities in the type of science education provided in Australia and in the United States. Teaching methods, for example, range from the traditional textbook-oriented approach to a laboratory, inquiry-oriented one. Also similar issues related to science education are being debated. Two areas of concern are the preservice education of science teachers and curriculum development. It is in this last mentioned area that the greatest innovation has occurred.
On The Trail Of The Decadent Polyglot, W. F. Hollander
On The Trail Of The Decadent Polyglot, W. F. Hollander
Iowa Science Teachers Journal
At the risk of beating a dead horse to death, I desire to add my lick. Students are not adequately trained to communicate in science, and the objective-type test is not helping. When linguistic fluency is equated with drooling in one's beard, and semantics is some sort of erotic deviation, one must not be surprised to learn that etymology is the study of incests. Most of the kids have become aware that mini means small, and that lunar means moon, and we should be grateful for such small advances, but the slippage in other areas is less cause for a …
Into The Crystal Ball For The 1970s, Joe R. Moore
Into The Crystal Ball For The 1970s, Joe R. Moore
Iowa Science Teachers Journal
The beginning of a new decade is always an ideal time to reflect upon the past-and the future. Looking back, the decade of the sixties can be characterized as the decade of tumult, the decade of change, the decade of progress-and depending upon one's past experiences-many other adjectives will probably be equally descriptive.

U.S. Army-Iowa Science, Engineering, and Humanities Symposium - In September, 1969, letters announcing this year's symposium and preliminary applications were sent to high school principals in Iowa and western Illinois. This year through the cooperation of the Iowa Academy of Science, initial letters and applications were also sent directly to the science teachers whose names were on the academy's mailing list. Included in the letter was a brief sketch of symposium activities and goals. The science teacher applications included nominations for student research papers and nominations for student symposium participants other than those applying to give papers.
Far-Nix And Lar-Nix Diesected, Charles J. Ellis
Far-Nix And Lar-Nix Diesected, Charles J. Ellis
Iowa Science Teachers Journal
High school teachers do a wonderful job. This observation is of long standing and particularly true when one considers the "handicaps" under which these teachers operate. They not only must give of themselves and of their time, but each must be the disciplinarian, father-confessor, and big-buddy of the students. They must cope with school boards and parents, take tickets and usher! For all their expertise in these many areas, we on the "outside" thank these teachers.
