The primary purpose of this study is to give simple and detailed instructions for building a log cabin by the post-and-beam method. The data were gathered from three sources: (1) library research, (2) interviews with experienced builders of cabins, and (3) personal experience in cabin construction. A step-by-step guide for building a cabin is given in Chapters II and III, which explain in depth how to construct each section of the cabin, from laying the foundation to putting on the finishing touches. It is believed that any serious builder can follow the directions and construct his own log cabin for less than one-third the cost of a similar commercially built cabin.

This study was made to gather data and information to aid the Burleson Independent School District in initiating an industrial arts general shop program in the Pauline G. Hughes Middle School. The data and information were obtained from the Texas Education Agency, the Burleson Independent School District records, the vocational director, the assistant superintendent, a questionnaire, and the Brodhead-Garrett 1976-1977 Catalog. The majority of the general shop programs in the north Texas area conduct classes five days a week for fifty-five minutes a day and accommodate twenty-four students per class. Furthermore, the majority of the general shop programs offer three units of instruction per year and teach one unit of instruction each quarter.

This history is designed to study the Industrial Arts Department at North Texas State University, The study is broken down into the areas of enrollment trends, the faculty, the curriculum, and the physical facilities. This study found that the Industrial Arts Department's class card enrollment remained relatively stable from 1955 to 1975. There was little fluctuation in semester credit hours in the Industrial Arts Department from 1955 to 1975. This study also found that the curriculum of the department is designed mainly for undergraduate students, The number of female students is increasing in the department and the number of degrees awarded by the Industrial Arts Department is declining,

This study seeks to provide a descriptive analysis of the role of industrial arts in career education. The criteria used as a basis for comparison of industrial arts and career education are (1) clarification of terminology, (2) historical trends in the development of both programs, (3) basic program philosophies, (4) curriculum content, (5) objectives and goals sought by each curriculum, and (6) legislation affecting industrial arts and career education. Career education is more extensive than industrial arts. Industrial arts cannot assume full responsibility for a comprehensive program of career education; however, industrial arts can be involved in activities which will help the student select a meaningful occupation related to industry.

The problem with which this investigation was concerned was that of determining the use of modern automotive tune-up equipment as used by the automotive garages in the Fort Worth area. The data for this study were provided by fifteen garages of the Fort Worth area. Of the Fort Worth garages using electronic equipment to perform a tune-up, few appear to have the adequate equipment and few appear to make more use of the equipment. In addition, a deficiency seems evident in the use of the electronic computer in performing tune-ups.

The problem of this study was to determine the type of metals used in the foundries in the high schools of Texas and the treatment of these metals. The data for this study were provided by thirty metalworking instructors of Texas high schools. Of the Texas high schools offering foundry as part of their metalworking curriculum, all included aluminum as a basic metal. In addition, the amount of metals used and their treatment varied from school to school.

The problem of this study was to determine to what extent industry was making use of closed circuit television as an implement of industrial security. The data for this study were provided by a group of thirty-two security chiefs of industry, and by another group of fifteen law enforcement officials in the Dallas and Fort Worth Metropolitan area. Of those industrial concerns making use of closed circuit television as an aid to security, a majority use the medium for surveillance of controlled access areas, with theft control and control of plant access following closely behind. For the most part, all surveyed thought that closed circuit television was very efficient.

The problem was to design and construct the necessary equipment to cut and fasten short stock end to end using finger-joints. The study was divided into five chapters: I contained the introduction to the problem; II was concerned with the design and construction of the equipment; III detailed the operation of the equipment; IV contained the presentation of the data; and V covered the summary and findings. The study concluded that the equipment could be constructed inexpensively, and would perform a useful service. Also, a student using waste wood salvaged through use of this equipment could expect a smaller bill for materials than if he purchased new wood.

This study was made to find the effects of noise on the human body, to measure sound levels that exist in school power laboratories, and to design and evaluate the effectiveness of two noise control devices. An accurately calibrated testing device was used to measure sound levels in an attempt to determine if excessive noise exists in school power laboratories and to find the extent to which such noise can be reduced by shielding or enclosing the engine test area. It was found that noise has undesirable physical and psychological effects on the human organism. Sixty-two and one-half per cent of the engines tested registered sound levels above 90 dBA; even so, simple, inexpensive noise control devices do control the noise levels generated in the school power laboratories.

This study was conducted in order to determine what safety practices and procedures were employed in the industrial plastics laboratories in the secondary schools of the Fort Worth Independent School District. Data were obtained from literature in the field of safety education in industrial arts and from an information form mailed to the teachers of industrial plastics in the Fort Worth Independent School District. Hazardous conditions were found to exist in a majority of the laboratories due to a lack of sufficient floor space and work stations and the absence of proper guards on machines, proper storage facilities for flammable liquids, painted danger zones and nonskid surfaces on floors around machines.

The problem of this study was to determine how much foundry equipment exists in the high schools of Texas and to determine to what extent it is being utilized. The data for this study were provided by thirty-seven metalworking instructors of Texas high schools. Of the Texas high schools offering metalworking as a part of the industrial arts curriculum, few appear to have adequate foundry facilities. In addition, a deficiency seems evident in the background and training in foundry of the metalworking instructors.

Information was gathered from the written works of industrial arts, general education, sociology, and psychology. The study offers a survey of work and leisure values which have evolved in the twentieth century. Also, it presents a historical perspective of industrial arts objectives relating to work and leisure values as they are influenced by the vocational, social, and general education movements. Finally, the study presents specific strategies and tactics which develop work and leisure values through industrial arts.

This study was designed to determine the employment opportunities in the steel fabrication industry of the Greater Fort Worth Metropolitan Area, and to ascertain what skills and knowledge were required of the prospective employee and which of these skills were being taught in the Industrial Arts metalworking laboratories. The Machine Metalworking I & II curriculum was established and related to information gained through a questionnaire sent to participating steel fabrication firms. The study was used to determine present and anticipated employment opportunities in the steel fabrication industry and aid in evaluating the curriculum of Machine Metalworking I & II as it relates to the employment requirements of the steel fabrication industry.

This was a comparative study in which Texas teachers of industrial plastics and the employers of Texas plastic industries were surveyed in order to evaluate the need for various knowledge and skills of the plastics industry. The respondents believed that basic knowledge of plastics was much needed, and knowledge of the thermoplastic family is of more importance than of the thermoset family. It was also concluded that knowledge of demonstration skills is of only average or lesser importance than knowledge of other areas.

The problem was to identify the technical competencies necessary for beginning industrial arts woodworking teachers in Texas public secondary schools. Twenty-seven clusters of competencies were listed on a questionnaire sent to ninety-one supervisors of industrial arts in eighty-six Texas school districts requesting that these supervisors evaluate each cluster as "Essential," "Desirable," or "Unnecessary." Sixty-six questionnaires were returned (72.53 percent). A weighted rating scale was used to determine an overall evaluation for each cluster, with the result that twenty-five of the clusters were judged to be "Essential" and the two remaining clusters were judged to be "Desirable." It was concluded that the clusters judged to be "Essential" should be part of the required curriculum and that more training in tool maintenance be given.

The purpose of this study was to determine topics being taught by power technology instructors in Texas and to develop a curriculum from these topics. This curriculum was meant to be a guide for a power technology course for the ninth grade. Questionnaires were distributed to power technology instructors in Texas. The topics from these questionnaires which instructors indicated they were teaching or they believed should be included in instructional content were made a part of the power technology curriculum. It was concluded most topics mentioned were in use or were indicated important to a comprehensive curriculum.

The purpose of this study was to identify the essential furniture and equipment needed for instructional programs in industrial arts in grades seven and eight in Texas public schools. The study includes a brief history of federal and state legislation affecting industrial arts and vocational education. A checklist containing items of furniture and equipment applicable to each of the twelve approved areas of Introductory General Shop in grades seven and eight was sent to industrial arts teachers, supervisors of industrial arts in the pilot programs, and industrial arts teacher educators in Texas. Over 51 per cent of the respondents agreed that a majority of the items listed in the checklist were essential or desirable for instructional programs in industrial arts in grades seven and eight.

The problem of this study was to determine the suitability of available industrial arts textbooks for classroom use in the subject area of power mechanics. Criteria used in determining the subject matter content and format suitability of the textbooks were selected from previous research and applied to the textbooks by five jurors. Only one of the eight textbooks evaluated for subject matter content was found suitable for use in courses in power mechanics, while all of the textbooks were found suitable when evaluated for format. In order to conduct a comprehensive industrial arts power mechanics program, teachers must rely on supplementary materials in classroom instruction because of the low levels of subject matter suitability of the textbooks.

This study surveyed teachers of industrial plastics and personnel of the plastics industry to evaluate an industrial-plastics curriculum guide. The respondents felt that there was no unnecessary material in the guide, that additional information should be added to several of the plastics processes in the curriculum guide, and that most of the subject areas in the guide should be studied for no less than an hour and no more than five hours.

The purpose of this study is to determine the public image of industrial arts education in Dallas, Texas. Information sought is obtained from interview schedules using random sampling techniques. The results of the study indicate that the public is not generally informed about industrial arts education. It is recommended that the public be informed as to the difference between industrial arts and vocational education. It is also recommended that more girls be introduced to industrial arts. It is further recommended that the world of construction and world of manufacturing be expanded.

The purpose of this study was to ascertain which assignments from the course outline for The World of Construction should be deleted, retained, or combined with each other to form the curriculum for an eighteen-week construction technology curriculum. The study contains a brief descriptive account of the development of the Industrial Arts Curriculum Project. Questionnaires asking for the opinions of experienced teachers of The World of Construction were distributed in the Dallas and Fort Worth, Texas school districts. Respondents indicated that the majority did not agree upon which assignments should be deleted, shortened and combined, and that all of the assignments were considered to be important and essential.

This study measures technical preparation and job demands among North Texas State University industrial arts graduates teaching in high schools. In addition to data from professional literature and the NTSU Bulletin, questionnaire mailings reveal that most graduates consider themselves qualified although recommending more semester hours of industrial arts for certification. They also affirm the practical value to the teacher of experience in industry. The study recommends narrowing the number of areas in industrial arts preparation and providing a more specialized teacher-training program with greater uniformity of semester hours.

This study of the feasibility of introducing certain economic concepts into secondary school industrial arts curricula reveals that most Americans understand economics poorly. The study divides economic concepts into seven major categories with which the responsible adult should be familiar. The study examines trends toward involving economics in contemporary industrial arts projects and presents selected such activities with an economic emphasis. The study concludes by distinguishing between suitable and unsuitable economic concepts for integration into industrial arts curricula.
