    Tutoring electronic troubleshooting in a simulated maintenance work environment

    A series of intelligent tutoring systems, or intelligent maintenance simulators, is being developed based on expert and novice problem solving data. A graded series of authentic troubleshooting problems provides the curriculum, and adaptive instructional treatments foster active learning in trainees who engage in extensive fault isolation practice and thus in conditionalizing what they know. A proof of concept training study involving human tutoring was conducted as a precursor to the computer tutors to assess this integrated, problem based approach to task analysis and instruction. Statistically significant improvements in apprentice technicians' troubleshooting efficiency were achieved after approximately six hours of training

    Smokeless Tobacco Use in Military Personnel

    Military personnel are more than twice as likely as civilians to use smokeless tobacco (ST), and recent studies indicate that military prevalence rates are rising. However, few studies have examined factors related to ST use in the military. The present study evaluated the characteristics of ST use in 785 active duty military personnel. The results indicated that the average age of initiation was 17.7 years, participants had used ST for 12.3 years, and they used approximately four tins or pouches of tobacco per week. Army personnel were more likely than Air Force personnel to be older, to have used ST longer, and to be heavier users. Officers had used ST longer than enlisted personnel and were more likely to have had a recent quit attempt. Enlisted personnel were more than three times as likely to report concurrent cigarette smoking. These results indicate that there are significant differences in ST use patterns in military personnel, and cessation programs should be tailored to meet these differences

    Content Preparation and Management for Web Design: Eliciting, Structuring, Searching, and Displaying Information

    No full text
    The vast amount of information available through the Web has made it difficult to retrieve information relevant to a specific task. To help ensure that users\u27 interactions with a system are successful, preparation of content and its presentation to users must take into account (a) what information needs to be extracted, (b) the way in which this information should be stored and organized, (c) the methods for retrieving the information, and (d) how the information should be displayed. The goal of this article is to discuss the generic problems facing content preparation and evaluate the current methods available to help remedy them, as well as identify areas in which more research is needed. The material presented in this article was a result of the collective efforts of the participants of a special white paper session that was part of the 9th International Conference on Human-Computer Interaction (HCI International 2001)
