It was hypothesized that distinct conceptual relationships are better displayed in a unitary complex science diagram relative to a text description. A second hypothesis stated that the placement of a textual description adjacent to a unitary complex science diagram generally will divert the learners' attention to the theoretically less effective…

A description of the Nuffield approach to biology for students 11-16 years of age, a discussion of the possible entry points to the materials provided for the five years of British secondary schools before the "O"-Level examination, an account of the type of examination to be expected, and estimates of the cost of introducing the program…

The purpose of this study was to determine if teachers who have a more humanistic pupil control ideology exhibit to a greater extent the classroom teacher practices recommended by the Biological Sciences Curriculum Study (BSCS) program as measured by the Biology Classroom Activity Checklist (BCAC) than do teachers who have a more custodial pupil…

Teaching notes for each of the 15 sections of the Scottish Integrated Science course, based upon the report of the Working Party on Secondary School Science (SE 015 432), have been written by teachers who taught the course in pilot stages. For each section there is a general introduction to the intent of the unit, a list of specific objectives, a…

If oxygen is attracted to a magnet, is there more oxygen in the air near the north magnetic pole? Explains why the answer to this question (posed by a high school physics student) is "no." (JN)

Investigated the claims made by science teachers as to how they write and use worksheets, validating these claims against an analysis of worksheets collected from these teachers. Some weakness of readability theory in terms of validity and reliability when applied to these materials are discussed. (JN)

Presents the theoretical advantages of banks of test items from which tests with pre-determined characteristics can be constructed, with particular emphasis on the possibility of providing comparable achievement data concerning students from different schools without forcing all to take exactly the same test. Reviews some related literature. (AL)

A survey of the life of a physics teacher who has been successful in making changes in curriculum. Describes work on an Australian adaptation of Project Physics. (DF)

Short articles describe the use of a lever to transfer energy between pucks on a frictionless surface, a demonstration of the principle of conservation of linear momentum, the construction of an inexpensive joulemeter, the design and construction of a simple logic demonstration board using integrated circuits, mounting of Geiger-counters to…

Short articles present ideas for demonstration equipment useful for the junior high school science: three-dimensional magnetic fields, model clocks, and smoke-ring puffers." (AL)

Describes the role of South Australian schools in the testing of units prepared by a national science curriculum development project preparing materials for grades 7-10 and answers questions concerning the nature of the materials. (AL)
