Computer‐based learning in psychology using interactive laboratories

Traditional approaches to computer‐based learning often focus on the delivery of information. Such applications usually provide large stores of information which can be accessed in a wide variety of ways. Typical access facilities provided within such applications include Boolean search engines and hypermedia (non‐linear) browsing. These types of approach often centre on providing human‐computer dialogues which are relatively low on interaction. The interactive‐laboratory approach, however, aims to limit the quantity of information presented, and instead to provide a highly interactive learning environment. In the field of psychology, users are able interactively to design and deliver a broad range of psychological experiments. This paper details the approach, and describes how it can be used to teach psychology within a university environment. The way in which its effectiveness as a learning tool can be evaluated is also discussed

Educational software design: Applying models of learning

Numerous psychological models exist which aim to explain how people learn, but the knowledge from educational theory is often missing from the design of computer‐based learning applications. This may stem from the abstract and complex nature of many learning models. In order to address this problem, there is a need for simplified models of learning which include guidelines indicating how such models can be implemented in courseware design. This paper identifies such a model, and presents a series of guidelines intended to enable courseware designers to apply educational theory to the practical design of quality computer‐based learning materials

Analysis of Issues for Project Scheduling by Multiple, Dispersed Schedulers (distributed Scheduling) and Requirements for Manual Protocols and Computer-based Support

Although computerized operations have significant gains realized in many areas, one area, scheduling, has enjoyed few benefits from automation. The traditional methods of industrial engineering and operations research have not proven robust enough to handle the complexities associated with the scheduling of realistic problems. To address this need, NASA has developed the computer-aided scheduling system (COMPASS), a sophisticated, interactive scheduling tool that is in wide-spread use within NASA and the contractor community. Therefore, COMPASS provides no explicit support for the large class of problems in which several people, perhaps at various locations, build separate schedules that share a common pool of resources. This research examines the issue of distributing scheduling, as applied to application domains characterized by the partial ordering of tasks, limited resources, and time restrictions. The focus of this research is on identifying issues related to distributed scheduling, locating applicable problem domains within NASA, and suggesting areas for ongoing research. The issues that this research identifies are goals, rescheduling requirements, database support, the need for communication and coordination among individual schedulers, the potential for expert system support for scheduling, and the possibility of integrating artificially intelligent schedulers into a network of human schedulers

Distributed project scheduling at NASA: Requirements for manual protocols and computer-based support

The increasing complexity of space operations and the inclusion of interorganizational and international groups in the planning and control of space missions lead to requirements for greater communication, coordination, and cooperation among mission schedulers. These schedulers must jointly allocate scarce shared resources among the various operational and mission oriented activities while adhering to all constraints. This scheduling environment is complicated by such factors as the presence of varying perspectives and conflicting objectives among the schedulers, the need for different schedulers to work in parallel, and limited communication among schedulers. Smooth interaction among schedulers requires the use of protocols that govern such issues as resource sharing, authority to update the schedule, and communication of updates. This paper addresses the development and characteristics of such protocols and their use in a distributed scheduling environment that incorporates computer-aided scheduling tools. An example problem is drawn from the domain of Space Shuttle mission planning

Intelligent approaches to performance support

Electronic performance support systems provide an important method of meeting on‐demand educational and training requirements. They also provide efficient and effective ways of enabling the knowledge and expertise within an organization to be shared. This paper discusses the design of a distributed electronic performance support system and the ways in which ‘intelligent agents’ based on expert systems and neural networks can be used to locate and share distributed expertise. A case study illustrating our approach to the implementation and use of intelligent agents is presented

Written Reference Services Policies for Public patrons in Public Law School Libraries

Public law school libraries are often the only or one of the few sources of legal information that the general public can access for free or low-cost. One of the main methods for a member of the general public to obtain the information is by using the help of reference or research services at the public law school law library. However, given the use of the library by the public law school community, a member of the general public is often guided to a written reference services policy. This paper explores what is contained in those reference services policies and suggests recommendations for future studies and methods to improve them for the general public
