Using Bruno Latour's framework of a "collective of humans and nonhumans", this paper presents an analysis of chemistry instruction in a high school curriculum and professional development setting to present the chemistry education community with a new way to think about reality and knowledge construction and, at the same time, to…

With the introduction of the Australian National Curriculum containing the "Aboriginal and Torres Strait Islander Histories and Cultures" Cross-Curriculum Priority (CCP) and "Intercultural Understanding" General Capability, there has been a renewed push to embed Indigenous content into secondary school subjects. This paper…

The authors describe a Modeling Instruction program that places an emphasis on the construction and application of conceptual models of physical phenomena as a central aspect of learning and doing science. (Contains 1 table.)

Learners become at-risk of failure for myriad reasons. Absenteeism and the resulting missed learning is one major reason students become at-risk of failure. Learners consistently in the classroom often participate in conversations about the relevance and/or application of the lessons but high absenteeism, coupled with frequent moves, means losing…

Determined were (1) the effectiveness of a series of Biological Science Curriculum Study (BSCS) Single Topic Film Loops to improve, in five periods of instruction, the ability of high school biology students to construct hypotheses relevant to selected questions on the investigator's test, and (2) whether a relationship existed between students'…

The basic dynamics of high speeds in one frame of reference is proposed as an approach to relativity. Students could use the methods of generalizing used with Snells law and thermal expansions. (DS)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)

Reports an attempt to infer from official statements and from course materials some of the assumptions and theoretical positions which underlie four high school physics courses: Nuffield Physics, ECCP's "The Man Made World," Harvard Project Physics, and PSSC Physics. (PEB)

MANY IDEAS TAUGHT IN ELEMENTARY PHYSICS TODAY ARE EITHER FALSE IN FACT OR ABSURD IN LOGIC, AND HAVING BEEN CARRIED ALONG BY TRADITIONAL PRACTICE, THESE ERRORS AND MISCONCEPTIONS CONTINUE TO BE PROMULGATED. MANY MISCONCEPTIONS AND ERRORS COMMONLY FOUND IN CURRENT TEXTBOOKS ARE EXAMINED. AREAS DEALT WITH ARE (1) FORCES, (2) GRAVITATION, (3) ENERGY,…

Describes alternate methods of schematically representing genetic lines of descent, and illustrates the different patterns obtained with random mating, line breeding, parthanogentic males, cloning, and grafting. (AL)

Uses photomicrographs to illustrate the advantages of simple phase optics for microscopy in school biology teaching. (AL)

Provides a list of birth dates of scientists born in January. Describes the use of these dates, displayed with the birthdays of students, to stimulate interest. (AL)
