A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

Defines images that teachers have of themselves within their teaching context. Employs a grounded theory approach and interviews to study how these images contribute to curricular decision making in six secondary school teachers. Analyzes the effectiveness of teacher images as tools for connecting teachers' past experiences to current curriculum…

This article describes data requirements in Public Law 99-457; discusses issues confronting states as they develop data systems, such as the problems of comprehensiveness, incompatibility, and confidentiality; examines data on numbers of infants and toddlers receiving early intervention services; and explores applications of a national database on…

Two approaches to measurement for instructional decision making (specific subskill mastery measurement and general outcome measurement) are described and illustrated with case studies. The paper concludes that measuring general outcome indicators can bridge traditional and contemporary assessment paradigms to form an innovative approach to…

Effective school principles can help provide successful programs for American Indians. Principles include a clear school mission, assessment of comprehensive needs and monitoring of student progress, appropriate curriculum and instruction, opportunity to learn, time spent on task, high expectations, safe and supportive school environment, good…

Reviews recommendations of the Carnegie report "Turning Points: Preparing American Youth for the 21st Century" with respect to the internal restructuring of middle schools and ways of integrating community and parental support. Discusses suggestions concerning small learning communities, core academic programs, ensuring student success,…

Reflects on Head Start's beginnings, its goal of enhancing children's social competence, and errors associated with the incorporation of evaluation measures and curricula that are cognitive in orientation into its programs. Concludes that such errors must not recur. Evaluation measures and curricula must reflect concern for the child's whole…

An interdisciplinary robotics project undertaken by students is described. The students acted as designers, innovators, and the engineers in designing a dancing robot. The origin of the problem, designing of the mechanical frame, pneumatics, digitized sound, and problems with the design are discussed. (KR)

Variables impacting on the communication skill development of the mainstreamed child with hearing impairments include physical and environmental factors, child/student factors, teacher/service provider factors, peer and classmate factors, classroom arrangement and environment, teacher and curriculum adaptations, student responsibilities and…

Discussion of visible models of training course organization covers uses for course designers, including clarifying course structure, planning lessons, communicating course requirements, and presenting a course overview; six steps to produce a visible model; and benefits for designers, instructors, and students. An example of a schematic diagram…

Examines the processes involved in building instructional systems that are based on artificial intelligence and hypermedia technologies. Traditional instructional systems design methodology is discussed; design issues including system architecture and learning strategies are addressed; and a new methodology for building knowledge-based…

Explains Total Quality Management (TQM), a participative management style, and examines its relationship to Instructional Systems Development (ISD) as it is used for curriculum development. Application of TQM principles to the ISD processes of analysis, design, development, implementation, and evaluation is suggested. (eight references) (LRW)

Describes the redesign of a CD-ROM database interface by the Congressional Information Service (CIS) that addressed the needs of novice, casual, and expert searchers in academic libraries. Topics discussed include the user profile, the task profile, redesign goals, interaction style, menu design and implementation, system structure and the search…
