Self-Paced Experiences: A Participant's Daily Log, Jay B. Thorniley
Self-Paced Experiences: A Participant's Daily Log, Jay B. Thorniley
Iowa Science Teachers Journal
As part of my educational requirements, prior to student teaching, at the University of Northern Iowa, I was required to participate in a self-paced classroom. The following is a daily log of my experiences in a class of 18 students in the course, Self-Pacing Biology Experiences (SPBE), at the Malcolm Price Laboratory School. These notes, taken over six weeks, should prove helpful to those teachers considering adoption of self-pacing programs.

The Potential Of Wild Plants As Food Resources, J. R. K. Robson
The Potential Of Wild Plants As Food Resources, J. R. K. Robson
Iowa Science Teachers Journal
The modern world is so full of scientific wonders that we often forget to look back in history and recognize landmarks that were just as significant as the discovery of the transistor, penicillin, or the laser beam. The history of our present day food is a prime example of a phenomenon that is considered to be too mundane to be taken seriously. Yet, thousands of years ago man made a scientific discovery concerning food that made possible the growth of settlements that became our cities.

Investigating Iowa's Weeds, Paul G. Jantzen
Investigating Iowa's Weeds, Paul G. Jantzen
Iowa Science Teachers Journal
The term "weed" is often defined as a plant out of place. A. C. Martin has complained that this definition reflects human bias and that pest plants are out of place only with respect to man's immediate purpose. In nature's scheme, they often serve useful functions such as providing food for wildlife throughout the growing season and covering barren soil, thus preventing soil erosion. Judging from their competitive success with many so-called desirable species, they are anything but out of place.

Implications Of Piaget For The Everyday Laboratory Experiences Of Children, Thomas E. Allen
Implications Of Piaget For The Everyday Laboratory Experiences Of Children, Thomas E. Allen
Iowa Science Teachers Journal
In recent years, we have seen a great increase of interest in the work of Jean Piaget. Educational psychology courses and magazines for teachers feature frequent discussions about the Swiss psychologist and his research. Such discussions, however, often dwell on his descriptions of the stages of intellectual development and the cognitive abilities characteristic of each stage. Such an emphasis on classification is unfortunate because it encourages categorization of children while diverting our attention from the more important aspects of Piaget's discoveries - Piaget has analyzed the learning difficulties of many children and how children learn and, by implication, has shown …

Intelligent Zinc
Iowa Science Teachers Journal
Recently, Professor Adon A. Gordus of the University of Michigan has been directing a study of more than 800 well-documented hair samples. Using atomic absorption spectroscopy and neutron activation, his study has uncovered some interesting correlations between academic performance and trace metal content of hair.

Annual Baby Booms : A Chi-Square Investigation, David R. Duncan, Bonnie H. Litwiller
Iowa Science Teachers Journal
Scientists frequently wish to determine whether an observed distribution of data is consistent with some theoretical distribution. For example, is a given set of data normally distributed, or is a given set of data "uniformly" distributed among various categories? A statistical tool for investigating these questions is the Chi-Square statistic.

Iowa Science Teachers Journal
The average person will be reluctant to admit that a work of art is beyond his level of comprehension; but he will, in the same breath and with certain pride, confess his complete ignorance of the principles which make his radio work.

Will It Work In Iowa?
Iowa Science Teachers Journal
The embankments of many Austrian highways today show on both sides of the road a new installation: game-warning reflectors which are designed to divert beams from car headlamps into the adjoining countryside. The basic idea for the installation of the reflectors has been derived from the studies of the Institute of Comparative Behavior Research in the Austrian Academy of Sciences, which concentrated on the effect on animals of "eyes" and "eye dummies."

Large-Scale Industrial Applications Of Solar Energy, W. C. Dickinson
Large-Scale Industrial Applications Of Solar Energy, W. C. Dickinson
Iowa Science Teachers Journal
Research on solar energy sponsored by the U.S. Research and Development Administration (ERDA), at the Lawrence Livermore Laboratory, has concentrated on finding and developing techniques that can be made economically competitive with fossil fuels and can be applied by industry on a large scale. The difficulty lies in making solar energy competitive, not in identifying large-scale application. Table 1 suggests the widespread need for large-scale applications.

Some High School Biology Electives, James H. Meyer, Robert Nelson
Iowa Science Teachers Journal
Cedar Falls High School, for many years, offered a science curriculum composed of traditional biology, chemistry, and physics courses. The percentage of students taking science courses began declining in the late 1960's, reaching a low of 573 students (out of approximately 1,500 students) in the 1972-73 school year. Since all science courses offered at the school were elective.it was concluded that some adjustment in course offerings was in order if a greater percentage of the student body was to be reached. As a result of the efforts of the science staff, five new biology courses were developed and subsequently introduced …
