Some National Trends In High School Science Education And Their Influence In Iowa, Jack Gerlovich Jan 1979

Some National Trends In High School Science Education And Their Influence In Iowa, Jack Gerlovich

Iowa Science Teachers Journal

In August, 1978, a NEW sponsored National Assessment of Educational Progress (NAEP) report was issued entitled, Three Assessments of Science: Changes in Achievement 1969-77. The report indicated a 4.7 percent decrease in science achievement scores for 17 year-old high school students since 1969. During the same time period, 2.5 percent and 1.4 percent declines were reported for 13 and 9 year olds in science, respectively. Declines were observed to be greater in the physical than the biological sciences.

Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta Jan 1979

Beyond The Metre (Part I), Richard S. Tompkins, Vincent N. Lunetta

Iowa Science Teachers Journal

This article is the first in a series discussing the wide spectrum of metric units. Metric education programs typically avoid measuring force, energy, and other physical quantities. Specialized units like the joule and pascal, however, will be appearing more and more frequently. How many Americans can confidently interpret a label rating a light bulb in lumens? This series of articles for the general reader will review the history of the metric units, the rationales behind their definitions and the fine points of their usage. Examples and exercises will relate the special units to every day experiences. This initial article will …

The Endangered And Uncommon Amphibians And Reptiles Of Iowa - Frogs, James L. Christiansen, Russell R. Burken Jan 1978

The Endangered And Uncommon Amphibians And Reptiles Of Iowa - Frogs, James L. Christiansen, Russell R. Burken

Iowa Science Teachers Journal

Iowa has 23 amphibian and reptilian species whose known populations or ranges within the state are so small as to justify their inclusion in the state's endangered or threatened list (Roosa, 1977). This paper is intended to inform the Iowa scientific teaching community of the plight of these species and to recruit help in gathering information relative to their distribution. Most of the information presented here has been accumulated by Christiansen and Bailey (manuscripts in preparation or in press) in their work on the amphibians and reptiles of Iowa.

Chameleons In The Classroom, David Fagle, Nancy Walden

Iowa Science Teachers Journal

What can you get at a pet shop that will change its color and your science teaching? You can get Anolis carolinensis, a unique and interesting reptile that has become a commonplace object of study in many progressive science classrooms. Anolis carolinensis, the American chameleon is not a "true" chameleon. "True" chameleons exhibit more dramatic color changes, but children are charmed and intrigued by the behavior and color changes exhibited by this American reptile.
