The following standards are offered as a basis for evaluating the various possibilities for such laboratory problems: 1. _Time._--This is probably the most important factor because, in the first place, many laboratory problems are far too time consuming, and, in the second place, the total time allotment for an art course is usually limited in the vocational program in homemaking. _Every article which can be justified for a school problem should require a relatively small amount of time and few repetitive practices._ 2. _Ultimate use of the article._--This is a factor which is often lost sight of and as a result girls make ruffled organdy or embroidered or quilted silk pillows for which they have no real use. _Every article should be evaluated in terms of its relation to use and surroundings and be chosen for a specific place._ 3. _Structural quality of the article._--"Structural design is the design made by the size and shape of the object."[24] Laboratory problems involving structural design afford opportunity to make use of several art principles, but to bring about structural beauty the pupil must have achieved real ability to use these principles. _Every article should meet the fundamental requirements of good design._ 4. _Suitable decoration for the article._--"Decorative design is the surface enrichment of a structural design." Too often decoration has failed to contribute to the appearance or to the utility of the article. _Decoration, if any is used, should make a lasting contribution rather than a temporary appeal._ 5. _Good technique._--An article may be well planned, with good design and pleasing decoration, and may be one that would not require too much time in the making, but the finished product may not be acceptable because of poor technique. _Laboratory problems should require only that type of technique which can be achieved successfully by the pupil._ The ultimate purpose of this particular part of the training in art related to the home is to enable girls and women to make selections for their homes that will contribute to their attractiveness rather than to produce artisans in the various crafts. Therefore the selection of class laboratory problems must be made most carefully. The teacher will need to emphasize repeatedly the importance of structural value, as well as the utility of articles if the pupils are to appreciate these qualities as more fundamental than decoration.
