The Objectives Of The Earth Science Curriculum Project: An Evaluation Of Their Achievement, Musa Y. Qutub, Keith M. Hussey

Iowa Science Teachers Journal

The textbook Investigating the Earth and its companion two-volume Teacher's Guide were conceived, written, and tested by a group of scientists and educators brought together for that specific purpose. A primary objective was to produce an earth science course that could replace the increasingly unsatisfactory and outdated general science program. The three main themes outlined for the program were behavioral, conceptual, and historical. Its major objective was to offer the ninth-grade students an interdisciplinary earth science course that would provide a view of our dynamic planet through the use of scientific concepts, such as space, time, energy, motion, and matter, …

Vertebrate Comparative Anatomy In Undergraduate Curricula 1969-70, Karl E. Goellner

Iowa Science Teachers Journal

In 1966 I presented a short paper describing some impressions of the status of vertebrate comparative anatomy (and embryology) in European universities (Goellner, 1968). Discussions which followed seemed to suggest that the status of these courses in the United States may be changing, and that a survey might elicit information on this matter. A basic assumption was implied, namely, that comparative anatomy had, indeed, been a traditional course in college offerings, particularly for zoology majors and for pre-medical and pre-dental students. This paper presents results of a modest survey conducted during the winter of 1969-70.

A Library Course Of Study - Investigation Outline, Mary Hantelman

Graduate Research Papers

I examined several course of study guides, textbooks, periodicals, and books on library curriculum as part of an investigation to determine what library skills were taught at each level. For each area I included the type or information found and then added my own conclusions for that section.

Following this, in outline form, is the library instructional program, 1 - 9, for the Oelwein Community Schools. The high school program is given in greater detail because I felt the outline form would not explain to the reader the rationale behind it. A.s a part. of the library program on the …

Environmental Education In The Environment, Michael J. Naylon

Iowa Science Teachers Journal

Man, the thinking animal, is an observer of events in the universe. He has conceded the obvious truth of his uniqueness on this planet and his religions charge him with its stewardship. However, the very quality which distinguishes him from other life forms has also proven to be his greatest weakness. Perception is a personal experience; its very nature mandates that it be point-centered in the universe. That point is the individual. Collective man is guilty of assuming that the universe "happens" around him. He has not effectively perceived that he is a happening in the universe. He has compounded …
