Many musicians have problems in keeping a regular rhythm or speed when playing their instrument. To help with this, most employ a metronome when practising. Metronomes produce a regularly emitted sound which can be altered in speed (between 40 beats per minute —largo, and 208 beats per minute —prestissimo) according to the speed of the music being played. They help discipline the musician into playing at the correct speed. For my GCSE electronics project earlier this year I decided to design and build an electronic metronome that also had the option of producing an accent every second, third or fourth beat — depending on the particular type of time signature — 2/4, 3/4 (waltz), or 4/4 ‘time’ of the music being played. This added option helps in disciplining the musician's mind into playing rhythmically.Therefore my design brief read: ‘I want to design a device that will give a regular ‘tick’ which can be varied in frequency to keep time for a musical instrument, i.e. a metronome. It will also have the option of giving emphasis on every second, third, or fourth beat.’

摘要:

In my GCSE courses I decided to use a unique approach for my GCSE Information Technology and Geography projects by using the school's weather satellite receiving station. This approach allowed me to link Information Technology and Geography but at the same time complete a separate project for each course. As well as saving valuable time, I found the projects more relevant.

摘要:

For many years the SATIS (Science and Technology in Society) project has supplied teachers of GCSE and A level science with excellent teaching support material. Initiated by the Association for Science Education, SATIS materials are sponsored and are aimed at putting science and technology into context. Many of these contents are social, industrial, agricultural or to do with Health and Safety.

摘要:

This is the second in a series of articles from the Dyfed Satellite Project, which examines how you can enhance your teaching by introducing satellite related work. An introduction to the work of the Dyfed Satellite Centre appeared in the Spring 1992 issue ofElectronics Education.‘The curriculum is already too crowded.’‘We can't afford the equipment.’‘We've got equipment but no-one on the staff knows how to use it.’

摘要:

This is the second part of an article examining how to design and build a simple digital thermometer and interface it to a BBC Microcomputer. The first part of the article, published in the Spring 1992 issue ofElectronics Education, examined the design stages of the project. This second part shows you how to assemble, test and calibrate your digital thermometer.

摘要:

Why bother linking a digicounter to a computer? The simple answer is that repeated measurements of the type in radiation experiments are more easily made using a datalogger or computer. The longer and probably more truthful answer is that I had read an article in the SSSERC Bulletin and a letter in Physics Education concerning a method of measuring airborne radon using a hoover and a piece of toilet roll and had been fascinated by the idea.

摘要:

National Curriculum Design and Technology will be formally assessed at GCSE level for the first time in 1995. However, many schools are looking to introduce their new courses for years 10 and 11 before 1993, either to link with new courses already operating for Key Stage 3 or as part of a revision of the whole curriculum initiated by the introduction of Key Stage 4 English, Mathematics and Science. As a response to these needs, Southern Examining Group has produced a syllabus for Design and Technology which reflects very closely the proposed requirements of National Curriculum Technology. This in turn has provided a framework for evaluating a number of aspects of the proposed new technology curriculum. One such aspect is the place of electronics in the school curriculum.
