A New Dimension in Teaching Experimental Science
Authors:A A  Aikman
Abstract:An instrument is now available that can combine the benefits of educational television with data obtained from carrying out an experiment. All students are able to see clearly what is happening, all can receive experimental results and some involvement in the experiment, and the lecturer knows in advance the details and results of that actual experiment, presenting the commentary as he or she chooses. The Bio Videograph B V2 allows analogue data to be encoded directly on to a videotape in perfect synchrony with the audio and video tracks. During replay of the tape, picture and sound are reproduced on a TV monitor and the data are decoded back on to the appropriate instrumentation, recreating the original data recordings. In areas of science‐based education where experiments and demonstrations are difficult to set up and carry out, long or tedious, expensive to perform, often repeated, or involve the controversial use of animals, this instrument could provide a solution. The savings in time and money from heavily committed budgets could be significant at the same time as providing an innovative and possibly improved method of teaching.
