The educational potential of agriculture stems from the diversity and tangibility of its components. As a science based human activity, it may provide the educator with a unique combination of educational opportunities in a context which is authentic and accessible to the pupil and to the teacher.

Surveys British people over age 15 with the purpose of assessing the level of scientific knowledge among the public. Discusses the relationships between highest level of formal education, sex, and the answers given to questions. Illustrates how little school science instruction is remembered into adulthood. (CW)

Discusses the history of scientific thought in terms of the theories of inertia and absolute space, relativity and gravitation. Describes how Sir Isaac Newton used the work of earlier scholars in his theories and how Albert Einstein used Newton's theories in his. (CW)

The purpose of this study was to investigate the relationships between students' conceptions of the nature of science and their reactions to evidence that challenged their beliefs about socio-scientific issues. The study used 248 students from 9th and 10th grade general science classes, 11th and 12th grade honors biology, honors science, and…

This paper reports on a study that examined the effects of formative experiences on the attitudes of preservice elementary teachers towards science and science teaching. Students in the science sequence of an elementary teacher preparation program wrote autobiographical essays about their experiences in science. These essays (n=56) were analyzed…

This document presents the framework and rationale for assessing the science achievement of students throughout the United States in 1996 and 2000. A general overview of the National Assessment of Educational Progress (NAEP) and the NAEP Science Framework adopted by the National Assessment Governing Board (NAGB) is provided. The process by which…

The teacher's guide of "Assessing Toxic Risk" aims to help students conduct scientific research on relevant environmental topics. Using the research protocols in this book, students learn to carry out experiments known as bioassays. In this way, the toxicity of substances is evaluated by measuring its effect on living things. The text is…

Models are used in everyday life and in school to predict and understand reality. In science classes, models should not be taught as absolute truths but used instead to promote reasoning. Exercises, strategies, and games are suggested to help students better learn about and use models. (DC)

Criticizes "On What Basis Hope? Modern Progress and Postmodern Possibility" (Danforth), which discusses the difficulty educators and special educators have in making arguments that do not conform to the language and conventions of science. The article cites Danforth's failure to acknowledge that people with disabilities themselves have challenged…

Discusses the early recognition of chaos as seen in Poincar's work solving dynamical problems. Proposes five examples from which an inventory of the manifestation of chaos can be inferred. Discusses some instructional consequences of the development of ideas of chaos. (MDH)

Examines how students use evidence, determines when they add further ideas and claims, and measures progress in understanding light propagation. Uses the Scaffolded Knowledge Integration (SKI) instructional framework for design decisions. Discusses design studies that test and elaborate on the instructional framework. (Contains 33 references.)…

This study investigates the proximal and distal images of the nature of science (NOS) that A-level students develop from their participation in chemistry laboratory work. We also explored the nature of the interactions among the students' proximal and distal images of the NOS and students' participation in laboratory work. Students' views of the…

Historical perspectives on science serve to humanize the sciences, increase student motivation, communicate academic content, and convey the nature of science. This paper briefly reviews pertinent literature regarding the history of science and narrates the author's experiences of incorporating historical perspectives in high school biology…

The paper describes a discussion strategy for secondary school students. The strategy focus the various dimensions of Science, especially the internal sociological and philosophical dimensions. Students are expected to learn more about Science, namely the role of controversy for scientific progress. The article contains key questions for the…

The investigators sought to design an instructional unit to enhance an understanding of the nature of science (NOS) by taking into account both instructional best practices and suggestions made by noted science philosopher Thomas Kuhn. Preservice secondary science teachers enrolled in a course, "Laboratory Techniques in the Teaching of Science,"…
