The purpose of this study is to develop and demonstrate the use of a conceptual framework for assessing the potential of "world view" as a concept for understanding important issues in science education. The framework is based on Stephen C. Pepper's treatment of six world hypotheses (animism, mysticism, formism, mechansim, contextualism, and…

The purpose of this interdisciplinary instructional design is three-fold. At its basic level it serves as an activity-based program guide for developing in students and instructors, grades 4-12, the ability to observe, assimilate and interpret the world around them. On another level it provides the "hands-on" experiences that open the bounds of…

The PLATO IV system of computer-based education developed at the University of Illinois is discussed. A brief description of the PLATO system operation is given, and lesson examples are provided for the areas of biology, geometry, chemistry, and physics. Basic problems in the field of computer-based education are discussed, along with possible…

Students investigated the salinity of tide pools at different levels in the intertidal zone. Data are analyzed collectively. Students graphed and discussed data. Included are suggestions for evaluation and further study. (Author)

This newsletter reviews declines in achievement test scores. American College Testing (ACT) program, Scholastic Aptitude Test (SAT), and National Assessment results are reviewed by geographic regions, age groups, sex, race, community type, and order of birth. Results in subject matter areas for 1965-66 and 1975-76 are also reviewed. Conclusions…

Cognitive preferences of 177 able, science-oriented high school students who participated in a secondary science training program at the University of Iowa in the summer were studied. A Biology Cognitive Preference Test (BCPT) was administered, in which 20 items required ranking and 20 items required rating on a four-point scale. The items were…

The reading level of selected marine science texts was ascertained using Fry's Readability Formula (Maginnis, 1969). Attached, with an annotated list of twenty texts, is a table that lists the reading levels for each text. (CS)

This booklet, one of a series developed by the Frederick County Board of Education, Frederick, Maryland, provides an instruction module for an individualized or flexible approach to 7th, 8th, and 9th grade science teaching. Subjects and activities in this series of booklets are designed to supplement a basic curriculum or to form a total…

Sample multiple-choice questions are examined for testing for three levels of knowledge in general biology: background or factual, operational, and analytic-synthetic. (ND)

Suggests that preservice teachers who develop an active interest in project work will continue to exploit it and feel self-confident to master new approaches to biology and to the techniques of teaching. (LS)

A field trip for identifying and collecting wild edible plants is described. (BB)

Discusses the use of a programed multi-image lecture approach for teaching a botany course to nonmajor students at the University of California, Berkeley. Also considers the advantages, production, method of presentation, and design of the multimedia lectures. (HM)

The demonstrations and experiments described in this article are appropriate for junior high school and older students, including beginning students in college biology or botany. Included are culture and observation of zoospores, zoospore attraction to plant roots, and other topics. (BB)

The river was investigated at six stations from source to estuary. Modifications of water quality and aquatic communities are related to man's activities in the river basin. The organization of the exercise and the method employed are described. (Author/BB)

A first-year university biology course with explicit prerequisites, made known to students a few weeks prior to the course, is described. Analysis of students' responses to a post-course questionnaire showed that most were satisfied with the high level of instruction. Certain preferences resulting from different high school preparation are noted.…
