Void Ratio And Shear Strength Of Two Compacted Crushed Stones, Fernando H. Tinoco, Richard L. Handy, James M. Hoover Jan 1966

Void Ratio And Shear Strength Of Two Compacted Crushed Stones, Fernando H. Tinoco, Richard L. Handy, James M. Hoover

Proceedings of the Iowa Academy of Science

Triaxial compression tests of two crushed limestones of differing highway service records indicate a fundamental difference in their shear strength-void ratio relationship. Analyses were based on stress parameters at minimum sample volume, i.e., before there was significant sample dilation due to shear. The better service record sample compacted to higher density, and had a high effective angle of internal friction and zero effective cohesion. The other sample compacted to lower density and had a lower friction angle, but gained significant stability from effective cohesion. Repeated loading-unloading cycles reduced the cohesion, apparently due to modification of the sample structure. Extrapolations of …


An Analysis Of The Outcomes Of Special Summer Programs For Secondary Students Of High Ability, Robert E, Yager, Gerald Krockover Jan 1966

An Analysis Of The Outcomes Of Special Summer Programs For Secondary Students Of High Ability, Robert E, Yager, Gerald Krockover

Proceedings of the Iowa Academy of Science

The National Science Foundation has supported special training programs for secondary students of high ability since 1959. This is the report of a study of the outcome of such programs upon the participants. Specific values of the programs were reported to be: 1) renewed interest in the remaining year of high school, 2) development of better study habits, 3) better oriented for college, 4) development of confidence, 5) verification and depending of vocational plans, and 6) general stimulation from a superior academic experience.


A Study Of The Laboratory Method Versus The Lecture Method Of Teaching Biology, Curtis E. Mcmallum Jan 1966

A Study Of The Laboratory Method Versus The Lecture Method Of Teaching Biology, Curtis E. Mcmallum

Proceedings of the Iowa Academy of Science

Two sections of biology students at the eighth grade level were taught a unit concerned with the cell with two different methods. One group experienced only lectures and discussions. The other group experienced only laboratory sessions. Although there were certain limitations to the study, the general results tended to favor the laboratory approach. This was particularly apparent in the case of the upper one-third of the classes.

Notes On The Status And Teaching Of Vertebrate Comparative Anatomy And Embryology In European Universities, Karl E. Goellner Jan 1966

Notes On The Status And Teaching Of Vertebrate Comparative Anatomy And Embryology In European Universities, Karl E. Goellner

Proceedings of the Iowa Academy of Science

During six months in Europe and Great Britain inquiry was made at 35 universities as to the status of vertebrate comparative anatomy and embryology in undergraduate curricula. People directly involved in teaching these courses were interviewed. Wide variation in programs was found, with evidence of a de-emphasis of morphology in many institutions.

Help! Help Your Substitute Teach Science, David V. Mccalley, Frank W. Starr, O. W. Eason

Iowa Science Teachers Journal

The science teacher often finds that to miss a day of school most frequently means to have lost a day of instruction. School administrators are experiencing serious difficulty in finding substitutes for teachers of the new B.S.C.S., C.B.A., CHEMS and P.S.S.C., programs.

Simple Radiation Studies In Biology, C. L. Christensen, D. J. Schmidt Jan 1966

Simple Radiation Studies In Biology, C. L. Christensen, D. J. Schmidt

Iowa Science Teachers Journal

Radioisotopes are a part of modern biological science. Radiation studies can be carried out without great expense. Thus they are available for the secondary level. Projects are easy to develop and can be adapted to any area of biological science. We would like to encourage all biology teachers to incorporate the use of radioisotopes into their programs.


Junior High Science As A Foundation, Leona K. Adler Jan 1966

Junior High Science As A Foundation, Leona K. Adler

Iowa Science Teachers Journal

Science programs designed for junior high school are usually based upon the assumption that this level includes grades 7, 8 and 9 - although, of course other types of groupings have been explored. We must also recognize the assumption that junior high school science is neither the first nor the last exposure of students to science.
