Meaning of the Term “Device”
Another term which has been used in educational discussions to distinguish between the more general modes of procedure and certain details of classroom work is the term “device.” A classroom device is some special piece of equipment or some particular way of dealing with a class that can be described as appropriate to a single classroom situation or to some topic of a given subject. For example, if a teacher of Latin has verb forms printed on cards for the purpose of drilling his classes in the recognition of such forms, his cards are spoken of as devices. Again, if one calls the roll by assigning a number to each member of the class and then requiring each number to be given in its order, it is said that one has a time-saving device.
