New Biology Book For Teachers

Iowa Science Teachers Journal

A new book, Creative Biology Teaching, by Delma Harding, Roger Volker, and David Fagle is just off the Iowa State University Press. The book was designed to help teachers solve the everyday problems they meet in the classroom and in the field, and to make them aware of the exciting challenges that exist in teaching modem biology.

Growth Of The White-Mouse Gastrocnemius Muscle I. In Terrestrial Gravity, Charles C. Wunder, John W. C. Bird

Proceedings of the Iowa Academy of Science

The gastrocnemius muscle from white mice (Swiss Webster, female; NLW, male and female; varying in age from 6 to 13 weeks and in body mass from 8 to 36 gm) were analyzed by means of Huxley's Equation for Heterauxic Growth where double logarithmic plots were performed of muscle size as a function of body mass. These mice had been grown in normal gravity. Relative wet mass, relative dry mass, and percent dry mass did not display significant changes with body mass. Percent noncollagen nitrogen [NCN] in the dry muscle, however, did show an effect which was not significantly different from …

High School And College Physics - Can We Match Impedances?, Herbert Priestley

Iowa Science Teachers Journal

Enrollments in high school and college physics have been declining in a serious fashion over the past few years. As a result, it is estimated that probably less than 10 per cent of the present national population has any experience in physics.

Supreme Court Voids "Anti-Evolution" Law

Iowa Science Teachers Journal

The United States Supreme Court has handed down a decision declaring unconstitutional the Arkansas statute prohibiting the teaching of evolution in the state's public schools. The National Science Teachers Association and the National Education Association filed a brief as amici curiae in support of the appellants, Mrs. Susan Epperson and H. H. Blanchard.

A Different Approach To The Study Of Pressure-Volume Relationship Of Gases, Harold Wengert

Iowa Science Teachers Journal

One of the problems in teaching science for general education is that all too often the ideas and concepts are given to the prospective learner before he has had an opportunity to wrestle with them himself.

Open Letter To Science Teachers: Let's Reflect For A Moment . . . ., Lynn W. Glass

A Summary Of A Survey Of Science Taught In Hampton Elementary Schools, Kenneth E. Moeller

Iowa Science Teachers Journal

In 1957 the Russians put an artificial satellite into orbit. Since that time science education in the United States has been experiencing a steady change. This change has not only been in course name and content but also in new methods of science teaching. The role of the science teacher is most important in the teaching of the new science materials. The instructor must be able to guide and direct the activities of the students, not just spew forth information. Often in the past, the instructor has taught as he had been taught. Most courses now are developed along these …

An Accurate Method For The Determination Of Surface Area, Larry L. Schenken

Iowa Science Teachers Journal

Many times it is necessary for teachers or students to determine the surface area of irregular objects (e.g., leaves) during laboratory investigations. The usual procedure involves laboriously tracing the outline of the object on graph paper, counting the number of square units on the paper, and then adding some "fudge factor" to estimate partially encircled squares.

Open Letter To Science Teachers, Clifford G. Mccollum

Iowa Science Teachers Journal

Our responsibilities as science educators have never been greater than they are today." I know personally that such a statement has been made regularly since the 1930s, and I suspect it was commonplace some before that. These responsibilities have had various emphases identified as the reason for their being. The emphases have included such applications as those made to industry, engineering, medicine, warfare, and space exploration.

Understanding Of Science By Elementary Teachers, Daryl D. Smith

Proceedings of the Iowa Academy of Science

This paper reviews some studies relating to the subject matter competency of pre-service elementary teachers. Attention is called to the importance of an understanding of the nature of science by the elementary major, and the need to measure this understanding. A study designed to test the understanding of and attitude toward science in elementary majors is discussed. The scores of elementary majors on the understanding of science measure are compared with those of other prospective teachers (both secondary and elementary). It is suggested that a measure of this type could be used as a basis for evaluation of innovations in …

Differences In Campus Attitudes, Academic Achievement And Socio-Economic Background Between Student Leaders, The Students For A Democratic Society And The Student Body At-Large At The University Of Northern Iowa, Oral M. Custer Jr.

Dissertations and Theses @ UNI

The purpose of this study was to identify similarities and differences between three groups of students, the Student Senate, the Youth for a Better Society (Students for a Democratic Society when the study was initiated), and a sample of students representative of the student body at-large at the University of Northern Iowa. These groups were objectively and subjectively evaluated to identify any similarities and differences in (1) their attitudes toward the University, (2) their academic achievement and aptitude, and (3) their socio-economic background. Objective measures of these variables included the College and University Environment Scales (CUES), cumulative grade point averages, …

Curriculum Evaluation Study And Recommended Revision For Dakota Christian High School, Martin Dekkenga

Dissertations and Theses @ UNI

The purpose of this study was to determine whether the curriculum at Dakota Christian High School (DCHS) was meeting the needs of its graduates. An auxiliary purpose_ was to share with the National Union of Christian Schools the findings of the study so that all member schools could have access to the information and thereby improve their own program or interest them in such an evaluation. The data was gathered by use of a questionnaire. Copies of the questionnaire were sent to most of the graduates of the ten graduating classes of DCHS. One hundred seventy-nine graduates were contacted and …

Measurement Of Physical And Chemical Changes Induced During Weathering Of A Carbonate Rock Unit, D. E. Simon, J. H. Elwell, L. V. A. Sendlein, J. Lemish

Proceedings of the Iowa Academy of Science

Changes which occurred during weathering of the Iowa Falls Member of the Mississippian Hampton Formation at Iowa Falls, Iowa were investigated quantitatively. The physical properties measured were: a) compressive strength, b) pore sized distribution, c) porosity and d) permeability. Chemically determined calcite and dolomite contents are related to the physical changes by utilization of an extensive sample sequence. The following changes are shown to be associated with the weathering process: 1) pore space and the degree of its interconnectedness increases with weathering, 2) calcite and dolomite are leached out during weathering, and 3) the rate of removal of calcite is …

An Analysis Of Student Outcomes In An Nsf Summer Institute For High-Ability Science Students, Glenn A. Isserstedt

Iowa Science Teachers Journal

After standardized testing of high-ability science students who were participants in a National Science Foundation Summer Science Institute, there is evidence to indicate that their understanding of science intangibles is dependent upon the section of the program in which they were enrolled. The participants in the mathematics and biochemistry sections demonstrated significantly better understanding of science.

Etymology: A Plea For Its Use In Early Education, Charles J. Ellis

Iowa Science Teachers Journal

My belief, based upon watching numerous students mature at Iowa State University, is, if etymology were stressed in primary and secondary schools, more older students would feel less burdened with so-called big, scientific names as well as nonscientific terms.

Open Letter To Science Teachers, Frank W. Starr
