The first of the three papers in this symposium, "Performance- and Learning Support with On-line Help Systems: An Effectiveness Study" (Theo J. Bastiaens, Jan N. Streumer, Yvette Krul) is a study of a method to cut training expenditures for production, planning, engineering, and inventory employees by implementing an online help system for questions and training needs. After 3 months, the employees still were below needed competence because of lack of training in using the online help system, the unsuitability of such a system to answer all training needs, and the lack of integration of the system with general training. The second study, "Readiness of HRD [Human Resources Development] Instructors to Engage in On-line Instruction" (Chanidprapa Suriya, Tim L. Wentling), which investigated the readiness of two groups of HRD professionals to engage in online instruction and use computer-mediated communication, found that respondents seem to have a positive attitude regarding their use of computers and new technologies, although they are not certain about the effectiveness of computer-based training in comparison to a traditional classroom. In the third paper, "Motivating Community College Instructors to Teach On-line: An Exploration of Selected Motivators" (James J. Kirk, Harold Shoemaker), the investigation explored differences in motivators for teaching courses online as reported by 405 instructors at 38 community colleges. The study concluded that selected motivators (making courses more accessible to students, receiving extrinsic rewards, challenges, and interest in computers) may motivate instructors to teach a course online, but that the motivators vary with the personal characteristics and demographics of the instructors.
