The history and meaning of the term "microelectronics" is reviewed, followed by a discussion of the key inventions of the Intel microprocessor in 1971 and the Texas Instruments electronic pocket calculator in 1975. The six characteristic features of microelectronic components are then defined. The UK prime minister Jim Callaghan's…

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.

Reports on the experience of teachers from 10 different secondary schools using information and communication technology (ICT) in science instruction. Discusses the teachers' thoughts on the materials they used, problems and advantages of using different applications, and necessary conditions for successful teaching outcomes. (Author/NB)

Outlines some of the developments in the use of information technology in education from the BBC Model A computer to CD-ROM and the Internet. Some examples of use are touched upon as are possibilities for the future. Emphasizes the effects of these examples on teaching and learning. (Author/ASK)

Presents examples of the types of investigations which exploit the tools now commonly featured in data-logging software. Emphasizes the importance of designing tasks that encourage pupils to think about the data and the principles which underpin worthwhile data-logging tasks. (Author/ASK)

Investigates pupils' abilities to interpret graphical information using a comparative study involving data-logging, conventional practical work, and a nonpractical equivalent. Concludes that the computer-based approach seemed to be particularly effective for younger and less-abled pupils. (Author/ASK)

Discusses reasons for using spreadsheets in science teaching. Presents a list of possible applications together with examples of these from very simple to more complex uses including animation of dynamic systems. Also provides a list of references for materials for beginners and more advanced users. Contains 12 references. (Author/ASK)

Reviews selected post-1989 research findings on the impact of computer-based technology in science teaching and learning. Provides brief insights into the use of various applications and describes some of the strategies that have been shown to be successful in terms of either promoting conceptual development in science or enhancing higher-order…

States that constructive thinking about variables seems to be a key to accelerated learning in science and that computer modeling can enable this. A taped sequence of a group in the exploratory use of a model reveals the potential of such activity. (Author/ASK)
