Types of Home Repairs and Improvements Made by People Who Maintain a Home and the Factors Influencing the Selection, Use, and Care of Tools and Equipment
Home repairs and maintenance are a necessary responsibility of any person who maintains a home. This responsibility can usually be met in one of two ways: first, someone can be hired to do the maintenance, or the person can do it himself. However, home repairs are costly and at times prohibitive to the average person who maintains a home. Then, too, there have been times in the past, especially during the war years, when it was next to impossible to secure the services of trained mechanics for home maintenance. During such time, and out of such necessity, many people began to make their own repairs and other improvements and, as a result, a gradual "do-it-yourself" movement has invaded all sections of the country. With the changing of times, with money a little more plentiful and manpower back in civilian life, do people who maintain their homes continue to make their own home repairs?
To Determine If the Industrial Arts Teachers of Texas Need Or Want State-Wide Industrial Arts Supervision
Industrial Arts today is included in a majority of the large high school curricula, and most school administrators do not consider the school program well rounded unless such work is offered. However, the Industrial Arts teachers of Texas do not have the advantage of a supervisor in their field of work. Each school is an entity in itself. There is no concerted state-wide program, no link between widely diversified needs and situations, no one to advise the young teacher beginning his work, and no one to aid the more experienced teachers in different situations. The State Department of Education recommends a uniform course of study, but each teacher is free to use his own interpretation of what he should teach and what he should not teach. Educators, mindful of the beneficial results of supervision in other fields, have asked for a State Supervision of Industrial Arts, and provision has been made in the next school budget for such an official if the Legislature approves. 1 The purpose of this investigation is to determine, if possible, whether a supervisory program is needed or wanted by the Industrial Arts teachers of Texas.
