Explores the reactions of third-year pupils to their science lessons. Discusses the extent to which these boys' and girls' reactions can be used to predict enrollment in the different branches of science in their fourth year. Describes ways to encourage students to continue in science. (CW)

Describes a study of students' ability to balance equations. Answers to a test on this topic were analyzed to determine the level of understanding and processes used by the students. Presented is a method to teach this skill to high school chemistry students. (CW)

Describes the characteristics of task-centered explorations. Provides definitions and examples of types of task-centered activities. Analyzes factors which produce an uneven distribution pattern in the type of explorations that pupils experience. Discusses the implication of these analyses for classroom teachers. (CW)

This article presents the teaching materials developed by the Science and Technology in Society Project (SATIS). Discusses how to demonstrate and assess the relevance of science. (CW)

Contains three articles designed to help practitioners with practical assessment for the GCSE. Articles include: "GCSE Biology Practical Assessment--Can the End Justify the Means?"; "Investigating the Effect of Catalase: GCSE Assessment Practical"; and "An Experimental Design for GCSE Physics." (CW)

Offers perspectives on the need for secondary science curriculum reform. Discusses curriculum issues in terms of four stages which include: the nature of science; principles of curriculum design; pupils needs and entitlements; and practical proposals for exploring curriculum models. (ML)

Provides descriptions and background information on: the use of workcards; Piaget and science curriculum analysis; a case for integrated science; the mechanism of aqueous bromination; integrating science/mathematics with language arts; and energy education. (ML)

Presents 23 experiments, demonstrations, activities, and computer programs in biology, chemistry, and physics. Topics include lead in petrol, production of organic chemicals, reduction of water, enthalpy, X-ray diffraction model, nuclear magnetic resonance spectroscopy, computer simulation for additive mixing of colors, Archimedes Principle, and…

Provides suggestions on how science teachers can, and should, deal with the nuclear weapons debate in a balanced and critical way. Includes a table outlining points for and against deterrence and disarmament. (JN)

Presents (1) suggestions on teaching volume and density in the elementary school; (2) ideas for teaching about floating and sinking; (3) a simple computer program on color addition; and (4) an illustration of Newton's second law of motion. (JN)

Discusses problems in using multiple-choice items on criterion-referenced tests, offering alternative methods to determine if objectives have been met. These include batteries of true-false items, structural communication grids, concept linkages, and a scoring system which takes partial knowledge into consideration. (JN)

Provided are reviews of science equipment/apparatus. Items reviewed include: Harris Micro-ecology tubes; Harris chromosome investigation kit; Harris trycult slides; a pressure cooker with thermometer; digital pH meter; digital scaler timer; electrical compensation calorimeter; and Mains alternating current ammeter. (JN)

Presents procedures, exercises, demonstrations, and information on a variety of biology topics including labeling systems, biological indicators of stream pollution, growth of lichens, reproductive capacity of bulbous buttercups, a straw balance to measure transpiration, interaction of fungi, osmosis, and nitrogen fixation and crop production. (DC)

Discusses an international conference which focused on the problem of "Girls and Science and Technology". Summarizes efforts by different countries to increase the numbers of women in science and technology, and lists recommendations from the conference. Conference proceedings are available from the author. (DC)

Presents observations of 30 high ability students participating in a three-day summer science course. Includes results of tests measuring divergent thinking given to students and student comments on the ideal science teacher, ideal science classroom, and cities of the future. (Author/JN)
