Fault Tree Analysis: An emerging methodology for instructional science

Fault Tree Analysis is a systematic approach to improving the probability of succes in any system. FTA was first developed as part of the U.S. Space Industry and was applied to such programs as the Minute Man Missile evaluations. Kent G. Stephens has successfully applied the technique to instructional and administrative programs, the latest program being the development of an FTA Institute for the Training Command of the United States Navy. More than a million dollars are being allocated to that program. R. Kent Wood has used the FTA methodology as a tool for a national needs assessment of teacher use of library media centers in the United States (NATUL Project). Bruce Barker has used the FTA methodology in religious education curriculum development. Because of the newness of the Fault Tree Analysis, coupled with its rapid acceptance as a tool for systems analysis and its very different approach of analyzing possible modes of failure in systems to increase the probability of success, this article is timely as the most complete coverage of FTA to date.     

Some Experiments in Man—Machine Interaction Relevant to Computer Assisted Instruction

Some experiments in man-machine interaction are briefly described in the context of their relevance to multi-media audio-visual instruction. Two important points emerge: the need for the development of appropriate data-base management systems and the necessity for a suitable author language capable of providing the instructor with a means of coordinating the use of instructional resources.     

Meanings within meanings: skilled readers activate irrelevant meanings of radicals in Chinese

Reading and Writing - Many characters in written Chinese incorporate components (radicals) that provide cues to meaning. These cues are often partial, and some are misleading because they are...     

Computer-Assisted Vocabulary Acquisition: The CSLU Vocabulary Tutor in Oral-Deaf Education

Deficits in vocabulary have a negative impact on literacy and interpersonal interaction for deaf children. As part of an evaluation, an outcomes assessment was conducted to determine the effectiveness of a computer-based vocabulary tutor in an elementary auditory/oral program. Participants were 19 children, 16 profoundly deaf and 3 hearing. The vocabulary tutor displays line drawings or photographs of the words to be learned while a computer-generated avatar of a "talking head" provides synthesized audiovisual speech driven from text. The computer system also generates printed words corresponding to the imaged items. Through audiovisual reception, children memorized up to 218 new words for everyday household items. After 4 weeks, their receptive vocabulary was tested, using the avatar to speak the name of each item. Most of the students retained more than half of the new words. The freely available vocabulary tutor, whose characteristics can be tailored to individual need, can provide a language-intensive, independent learning environment to supplement classroom teaching in content areas.     

A Practical Introduction to Authoring for Computer-Assisted Instruction. Part 5: PHILVAS

Interactive videodisc technology is likely to have a significant impact upon many aspects of education and training. However, before this medium can be effectively utilized considerable attention must be given to overcoming the present problems associated with courseware authoring. Solutions to these problems are to be found in the provision of suitable courseware development aids. In particular, there is a requirement for a powerful and easy-to-use author language. This paper describes the approach used by the PHILVAS authoring system.     

When group work leaves the classroom does group skills development also go out the window?

In moving towards what Lemke (1996) terms the ‘interactive learning paradigm’, higher education has adopted two key principles consistent with group learning technologies:

• ? learning is always mediated by and occurs through language ( Falk, 1997 ; Gee, 1997 ); and
• ? learning is distributed across a range of other people, sites, objects, technologies and time ( Gee, 1997 ).

A third and relatively recent principle to emerge on the higher education scene that seems to ‘contradict’ accepted views of group learning technologies is that:

• ? many universities now choose to offer ‘learning resources’ online.

This paper asks whether Information and Communication Technologies (ICTs) are ‘robust’ enough to support, sustain and address industry, employer and government calls for greater attention to group skills development in university graduates. Data features an examination of respondent feedback (n = 171) in an ‘ICT‐rich’ group work setting, and the subsequent ratings of group skills development over a 13‐week period. This discussion offers an account of learner outcomes by adopting Kirkpatrick's (1996) four levels of evaluation of learning as a classification scheme for determining learner satisfaction (Level One), the effectiveness of learning transfer (Level Two), its impact on practice (Level Three) and the appropriation of learning behaviours by participants (Level Four). The contrasting patterns of ICT use between female and male users in the data are discussed in relation to building social presence and producing social categories online. Differences reported here indicate that ICT group work is moving forward, but opportunities to challenge rather than reproduce existing learning relations and differences, remain largely unresolved.
