Social interactions profoundly impact the learning processes of learners in traditional societies. The rapid rise of the Internet using population has been the establishment of numerous different styles of network communities. Network societies form when more Internet communities are established, but the basic form of a network society, especially…

This article discusses the use of propensity scoring in experimental program evaluations to estimate impacts for subgroups defined by program features and participants' program experiences. The authors discuss estimation issues and provide specification tests. They also discuss the use of an overlooked data collection design--obtaining predictions…

Business communication courses are ideal for teaching visual communication principles and techniques. Many assignments lend themselves to graphic enrichment, such as flyers, handouts, slide shows, Web sites, and newsletters. Microsoft Publisher and Microsoft PowerPoint are excellent tools for these assignments, with Publisher being best for…

The authors stress the role of the multidisciplinary team in vocational rehabilitation, particularly the industrial engineer, in performing job analysis and workplace design to accommodate disabled persons in industry. Steps to effective job adaptation are charted, and methods of job analysis are discussed. (Author/MC)

This four-part manual assists child care providers working in day care centers, Head Start Centers, or nursery schools to design the physical space of both indoor and outdoor settings for infants, toddlers, preschoolers, and younger school-aged children. Part 1 stresses the importance of the physical environment in the child care setting. Part 2…

Discusses the various problems encountered when scheduling examination timetables and a means for overcoming them using a computer-based examination management system to provide the registrar with an analysis and feedback to eliminate conflicts. The system uses color-coding to produce blocks of nonconflicting examinations. (EAO)

Discusses the redesign of educational systems and presents a designing matrix to help select boundaries of a new system. A conceptual framework for exploring educational system boundaries is described, systems models are discussed, and the three cells of the matrix are explained. (LRW)

Discusses the new classroom acoustics standard, ANSI Standard S12.60, which specifies maximum sound level limits that are significantly lower than currently typical for classrooms. Addresses guidelines for unducted HVAC systems, ducted single-zone systems, and central VAV or multizone systems. (EV)

Discusses the role of algorithms in the design of computer-assisted instruction (CAI). Structural and processing characteristics of algorithms are analyzed, instructional algorithms are explained, empirically based design rules are presented, and the use of instructional algorithms in artificial intelligence is described. (44 references) (LRW)

Addresses the importance of research and development in the field of educational technology, based on reflections of previous articles and a symposium. Highlights include the centrality of design; the enabling capabilities of technology; collaboration; scaling up of projects; the use of alternative research methodologies; and instructional systems…

Describes Project DL whose goal was to provide a Web site where diverse information sources on digital libraries are available. Discusses the Web site design at the University of Missouri-Columbia that includes three sections: digital library collections, digital library resources, and digital library Web sites. (Author/LRW)

Describes the upgraded design of Canisius College's Lyons Hall, Buffalo, New York, from an academic building to a more inclusive facility containing necessary administrative functions. Before and after photos are included. (GR)

Sophomore year is an intense introduction into the theories and skills germane to the profession of Industrial Design. Design projects will address one to three design elements at a time to promote understanding and manipulation of concepts, such as: (a) theories of two and three dimensional form development are practiced and presented; (b)…

The events that led to the spectacular destruction of the Space Shuttle "Challenger" in 1986 are detailed here. They show how NASA should have heeded engineers' worries over materials problems resulting from a launch in cold weather. Suggestions are made of how pupils could also learn from this tragedy. (Contains 4 figures and 2 footnotes.)

Drafters must be detail-oriented people. The objects they draw are interpreted and then built with the extreme precision required by today's manufacturers. Now that computer-aided drafting (CAD) has taken over the drafting profession, anything less than exact precision is unacceptable. In her drafting classes, the author expects her students to…
