Focuses on the advice and support from science inspectors or advisers with respect to the use of living organisms in schools. Reports that advice, support, and encouragement in the use of living organisms in teaching was widely available at the time of this study and schools have a great deal to lose from the shrinkage in the advisory service.…

Focuses on the provision of meaningful counterintuitive experimental evidence for students while taking into account the relations of theory, instruments, and experimental data. Discusses the use of experiments designed to test pupils' conceptual framework during the teaching of introductory electricity. (JRH)

Examines the general philosophical nature of models in science and the relationship between models and analogies. Applies these ideas to molecular models in particular. (Author/JRH)

Describes a convenient and economical questionnaire that science teachers can use to assess their students' perceptions of classroom environment and reports a case study of a science teacher's successful use of this questionnaire in guiding improvements in his classroom environment.

Presents research into the quality of data analysis in practical activity in science using information technology. (Author)

Author states environmental archaeology involves reconstructing past environmental conditions from archaeological evidence, allowing development of earlier human societies to be understood in relation to factors such as their food supplies, state of health, etc. This article illustrates links between archeological and environmental evidence, and…

The author explains that randomlike serial data of different provenance are shown to contain a hidden common pattern which is governed by a simple law--the "Law of Statistical Relaxation." A model is introduced for illustrating how to interpret this law, and some applications are considered. (PR)

Investigates students' ideas, conceptions, and misconceptions about acids and alkalis before and after a teaching sequence in a small-scale research project. Concludes that student understanding of acids and alkalis is lacking. (DDR)

Discusses the explosive growth of the Internet, the World Wide Web in particular, and how it presents enormous opportunities for learners to access information; to communicate with peers, teachers, and other experts worldwide; and to collaborate on projects. Considers the real challenges the Internet provides to teachers and to the formal…

Describes a project in which a group of primary school students tried out a range of IT activities using Xemplar Pocket Book computers. Demonstrates that they improved the quality and range of pupils' learning and supported literacy in science. Explains that pocket computers do not replace but complement the classroom PC. (Author/ASK)

Demonstrates the possible confusion arising from the terms 'weak acid' and 'weakly acidic' in different contexts. Suggests some reasons and possible approaches for overcoming these confusions. (Author/ASK)

Uses alkaline phosphate to remove the phosphate group from phenolphthalein diphosphate. Discusses problems which include the interference of ambient light and temperature variation. Provides detailed information about the apparatus and the experimental procedure. (ASK)
