This study determined the effect of written persuasive communication on changing the attitudes of Egyptian preservice biology teachers toward teaching the topic of organic evolution. Attitude change was measured by administering an instrument (the Attitude Toward Teaching Evolution Scale) developed for the study. This 22-item, Likert-type scale…

The world is a dynamic environment driven by technology that challenges each individual in a unique way. No longer is the ability to read and write sufficient because technological change affects nearly every aspect of one's life from "enabling citizens to perform routine tasks to requiring that they are able to make responsible, informed…

Mathematics and Living Things (MALT) is designed for grade eight to enrich and supplement the usual courses of instruction. MALT utilizes exercises in biological science to derive data through which mathematical concepts and principles may be introduced and expanded. The Teacher's Commentary includes suggestions for instruction, a list of needed…

This article focuses on the paradoxes and developmental injustices in the socialization of women's sexuality. It traces these paradoxes to an historical concern with female sexuality which centers on the reproductive cycle; sketches the processes of socialization which create a developmental injustice in the expression of sexuality in the older…

This paper argues that understanding women requires attention to four large classes of variables: biology, socialization, life chances, and personality. The implications of these variables are discussed. Emphasis is placed on intrasex variability, and on the need to study women as women, not in contrast to men. It is pointed out that female…

Five packets comprise the marine science component of an enrichment program for gifted elementary students. Considered in the introductory section are identification (pre/post measure) procedures. Remaining packets address the following topics (subtopics in parentheses): basic marine science laboratory techniques (microscope techniques and metric…

Describes a six week summer course for junior high school students designed to acquaint them with one of the many branches of oceanographic studies. (PB)

Designed for quick, easy identification of some of the most commonly encountered organisms found in and around the school ground, this illustrated guide identifies by a picture and a short biological description the common animals and plants found in and around school lawns, house lawns, parks, fence rows, flower gardens, vacant lots, and…

Suggesting that headings provide useful cues for input/output processing, this investigation examined the utility of intact (topic outline format) and embedded (appropriately positioned within text) headings as processing aids with non-narrative text material under conditions of immediate and delayed recall. Passages were selected from biology…

Radiation has been a serious concern to individuals for over 100 years. A process by which an atomic nucleus emits particles to reach a more stable energy state, radiation harms living cells (usually by inhalation and absorption into the lungs) by causing abnormal cell function and structure. Man is constantly exposed to background radiation, both…

Defining a "misconception" as an error of translation (transformation, correspondence, interpolation, interpretation) between two different kinds of information which causes students to have incorrect expectations, a Taxonomy of Errors has been developed to examine student misconceptions in an introductory biology course for science…

The relationship between high school sophomores' (N=214) self concepts in science and their science achievement, mental ability, and sex were investigated. The Self Concept in Science Scale was used as a measure of students' self concepts. Science achievement was measured by the students' tenth-grade final examination in biology. The measure of…

Presented in this unit are three activities concerning the causes and effects of oil spills and methods used to clean up these spills in the oceans and Great Lakes. Students construct and interpret a graph showing oil pollution sources. The students create and try to clean up a small-scale oil spill in a pan, and they compare the water quality of…
