The authors express their concerns about attempts (completed and anticipated) to censor science content in textbooks and provide examples of censorship of material on evolution in biology textbooks. (PEB)

Provides directions for construction of a working model of the eye and specifies some experiments using this model. (PEB)

Provides a condensed report of a study of variables related to conservation knowledge. (PEB)

Described is a study of two types of individualized instruction, using two BSCS Green Version biology classes in a Minnesota high school, to determine what effect freedom for the student to develop or select his learning experiences had upon (a) his academic achievement, (b) how well he perceived he could achieve academically, and (c) how much…

The application of physical principles in solving mathematics problems have often been neglected in the teaching of physics or mathematics, especially at the secondary school level. This paper discusses how to apply the mechanical principles to geometry problems via concrete examples, which aims at providing insight and inspirations to physics or…

Discussed and questioned is the credibility of the widely-held view concerning the role of impartiality and crucial experiments in science as exemplified by the 18th century controversy between Spallanzani and Needham. Science teachers are cautioned to remember that performing investigations and conducting experiments are tasks not entirely devoid…

Three elementary school science curriculum projects, Elementary Science Study (ESS), Science - A Process Approach (S-APA), and Science Curriculum Improvement Study (SCIS), are compared concerning the biologic content each project contains. The reviewer found a lack of activities designed to represent functions at the cellular level. Two projects…

Examined are the rationale, methods and results of using social issues in high school biology as exemplified in the biology program at Parkway West Senior High School, Ballwin, Missouri. Criteria for selecting content to be used in the course are given. (PEB)

One of a series (see SE 511 542 - 544) of articles dealing with views of individual science educators concerning the future of secondary science education as exemplified by developments at the individual's college or university. Discussed in this article are implications arising from competency based teacher education programs. (PEB)

One of a series (see SE 511 541, 543, and 544) of articles dealing with views of individual science educators concerning the future of secondary science education as exemplified by developments at the individual's college or university. Briefly described in this paper are some developments at Governors State University which serves an urban,…

Presents one educator's opinion concerning the need to think carefully before deciding to teach science to streamed groups of students (Sectioned on the basis of intelligence test scores) or to individualize science content for students in schools in the United Kingdom. (PEB)

Outlines simple statistical procedures that may be effectively used in several ecology exercises suitable for secondary school science classes. (JR)

Describes current experiments that help to explain chemical processes which probably existed prior to the first living cells. Some experiments suggest that a significant portion of a major metabolic pathway, the Krebs cycle, may have developed in the earth's primitive atmosphere to be later incorporated into living organisms.
