This is a study of the drafting curriculum in the Fort Worth public high schools, Fort Worth, Texas.The specific purposes or the study were as follows: 1. To review and compare the courses and content of the drafting curriculums listed in the bulletins of the TEA and the Fort Worth Public Schools. 2. To study drafting scheduling procedures in each of the Fort Worth public high schools. 3. To study the courses and contents of the drafting curriculums offered in each of the Fort Worth public high schools. 4. To determine if there are variations from school to school in curriculum content of the drafting courses in each of the Fort Worth public high schools. 5. To offer suggestions and recommendations for improving the program, if weaknesses were evident, when the program was evaluated by acceptable criteria (12, 13, and 14).

The purpose of this study was to develop a course of study on Plane Geometry for the 8th grade, based upon the Instructional Systems Analysis technique. The systems model used was that developed by Bartel.The entire study involved identifying, selecting, and sequencing learning tasks. An elaborate review of resource materials on Plane Geometry yielded one hundred and fifty-five related tasks.The instrument developed to gather pertinent data had two parts to it. Part one contained seventeen items relating to the personal profile of the respondent. Part two consisted of the one hundred and fifty-five identified, verified, and correctly stated manipulative tasks. The tasks were grouped into two broad divisions. Each respondent rated each task on a 3-point scale according to the level of instructional importance he/she judged the task(s) should receive. A rating of 3 represented the highest level of importance; 2, average; and 1, least.The survey utilized the services of sixty-eight Nigerians currently on the Technical Teachers Training Program (TTTP) in the U.S. Information regarding the institutions and population of Nigerians on the program was obtained from the Training and Development Program (TDP) office in Washington, D.C. From the list of thirty-two possible institutions, twelve institutions met the criterion for participation.A Five-Interval Sampling Technique (FIST) was used to select subjects from the participating institutions. This gave the researcher a possible seventy subjects. Each subject's participation was purely voluntary. Thus the 73.6 percent return was considered satisfactory.The interpretation of data involved two analyses. Analysis one dealt with biographical information on each participant. The second analysis computed the summary of task ratings on the one hundred and fifty-five instrument items.Selection of tasks for inclusion in the course of study reported in this study was based on the judgments of the subjects. Higher mean values were used as the basis for selection. Overall, thirty top tasks were selected and sequenced for the purpose of the course of study under investigation.

The study addresses the automated translation of architectural drawings from 2D Computer Aided Drafting (CAD) data into a Building Information Model (BIM), with emphasis on the nature, possible role, and limitations of a drafting language Knowledge Representation (KR) on the problem and process. The central idea is that CAD to BIM translation is a complex diagrammatic interpretation problem requiring a domain (drafting language) KR to render it tractable and that such a KR can take the form of an information model. Formal notions of drawing-as-language have been advanced and studied quite extensively for close to 25 years. The analogy implicitly encourages comparison between problem structures in both domains, revealing important similarities and offering guidance from the more mature field of Natural Language Understanding (NLU). The primary insight we derive from NLU involves the central role that a formal language description plays in guiding the process of interpretation (inferential reasoning), and the notable absence of a comparable specification for architectural drafting. We adopt a modified version of Engelhard's approach which expresses drawing structure in terms of a symbol set, a set of relationships, and a set of compositional frameworks in which they are composed. We further define an approach for establishing the features of this KR, drawing upon related work on conceptual frameworks for diagrammatic reasoning systems. We augment this with observation of human subjects performing a number of drafting interpretation exercises and derive some understanding of its inferential nature therefrom. We consider this indicative of the potential range of inferential processes a computational drafting model should ideally support. The KR is implemented as an information model using the EXPRESS language because it is in the public domain and is the implementation language of the target Industry Foundation Classes (IFC) model. We draw extensively from the IFC library to demonstrate that it can be applied in this manner, and apply the MVD methodology in defining the scope and interface of the DOM and IFC. This simplifies the IFC translation process significantly and minimizes the need for mapping. We conclude on the basis of selective implementations that a model reflecting the principles and features we define can indeed provide needed and otherwise unavailable support in drafting interpretation and other problems involving reasoning with this class of diagrammatic representations.

D.Ed. / Currently, the passrate for Engineering Drawing presented at Technical Colleges is unacceptably low. This study is an extension of an earlier study done in the same studyfield, by the same writer. A need has thus arisen not only to investigate the problem areas responsible for the high drop-out rate in Engineering Drawing, but also to investigate the possibility of the early identification of the potential riskstudent in Engineering Drawing. In an attempt to address this problein further, the aim of this study therefore is to develop an appropriate measuring instrument which may be used to identify the potential riskstudent in Engineering Drawing. Five Technical Colleges on the Eastrand in the Gauteng Province - catering mainly for black students - were included in the investigation. For the research study the "Trade Aptitude Test Battery" (TRAT), compiled by the Human Sciences Research Counil, was used. The results of this study, clearly showed three-dimensional spatial perception (subtest 16 of the TRAT) as the only factor to be used when identifying the potential riskstudent in Engineering Drawing. Subtest 16 of the TRAT could then be used as an "criterion" to identify the potential riskstudent in Engineering Drawing. Lastly this study showed that to master Engineering Drawing requires a great deal of spatial ability. Lecturers presenting this subject will therefore have to take into account the recommendations of this study as set out in chapter 9 when enrolling students for Engineering Drawing. Subject specific remedial programmes should be utilized to improve the successrate in Engeneering Drawing of the identified potential riskstudent in Engineering Drawing.

M.Ed. (Curriculum Studies) / The future economic development of South Africa largely depends on the training of a career-skilled corps of workers. The current conventional educational system cannot provide in the demand for a career-skilled corps of workers on a large scale. Distance education in its different variations is gaining ground in increasing measure and can be regarded as a possible solution for the educational problem. Because of the distance between the lecturer and the student intensive attention needs to be given to the study material - especially the arrangement of the learning content to make the learning experience more effective. The design of a modular training program is a possible method to ensure effective self-study material. Modular training is aimed at accompa- nying the student meaningfully through objective-directed learning content. The Technical College of South Africa (Technisa) is one of South.Africa's distance education institutions. Currently a movement is taking place in the direction of a type of modular training which is known as the Technisa Modular Training (TMT) programme. One of the career-orientated subjects offered is Technical Drawing. In order to offer the training of Technical Drawing more effectively the subject contents are ordered according to the Technisa Modular Training programme. In this study a literature study has been done to define the concept distance education; to list the advantages and disadvantages; to scrutinise the total modular system as teaching strategy; to determine the components of a subject curriculum and adjust it according to the Technisa Modular Training programme.

Visual media are of great importance to designers. Understanding a new design, for example, often means understanding a drawing. From the perspective of artificial intelligence, this implies that automated knowledge acquisition in computer-aided design can productively occur using drawings as a knowledge source. However, this requires machines that are able to interpret design drawings. I view the task of interpreting drawings as one of constructing a teleological model of the design depicted in the drawings, where the model enables causal and functional inferences about the depicted design. I have developed a novel analogical method for constructing a teleological model of a mechanical device from an unlabelled 2D line drawing. The source case is organized in a Drawing Shape Structure Behavior Function (DSSBF) abstraction hierarchy. This knowledge organization enables the analogical mapping and transfer to occur at multiple levels of abstraction. Given a target drawing and a relevant source case, my method of compositional analogy first constructs a graphical representation of the lines and the intersections in the target drawing, then uses the mappings at the level of line intersections to transfer the shape representations from the source case to the target. It next uses the mappings at the level of shapes to transfer the structural model of the device from the source to the target. Finally, the mappings from the source to the target structural model enable the transfer of behaviors and the functional specification from source to target, completing the analogy and yielding a complete DSSBF model of the input drawing. The Archytas system implements this method of compositional analogy and evaluates it in the domain of kinematic devices such as piston and crankshaft devices, door latches, and pulley systems.
