This is a study of the safety in the industrial arts laboratories in the Dallas Independent School System. A questionnaire was sent to each instructor of industrial arts metalworking, woodworking, electricity, and power mechanics, and included nine main areas of safety.

The purpose of this investigation was (1) to perform hearing screening tests on 100 youths who are classified as delinquent; (2) to evaluate more completely the hearing of those who fail the hearing screening tests in order to determine the nature and severity of the losses; and (3) to determine whether or not any significant number of the youths tested demonstrate nonorganic components in their reported audiometric thresholds.

The purpose of this study was to measure perseverance time as related to the individual's need for achievement, past success or failure, the difficulty of a task, and the experimenter's instructions regarding its difficulty. The subjects used in this study were twenty-eight children, fifteen males and thirteen females, who ranged in age from eight years, six months to nineteen years and nine months, with the mean chronological age being twelve years and ten months.
