Multilevel Structured Documentation
研究了不同经验水平的用户在使用文字处理程序时，全局概览、详细步骤及两者结合的文档形式对问题解决、信息记忆和主观反应的影响，发现结合型文档效果最佳。
This research examined the effects of different types of documentation on the performance of users with different levels of experience on a word-processing program. Three forms of documentation (global overview, detailed step-by-step, and combined global and detailed) were presented to undergraduates with high, medium, and low levels of computer experience. Dependent measures were problem-solving behavior using a word-processing program, the amount of information retained by the participants about the program, and subjective reactions to the documentation. The results indicated that (a) combined global and detailed documentation was, in general, superior to either type of documentation alone; (b) more experienced users were superior in reading documentation more quickly and solving problems more quickly, but they did not have significantly better recall or recognition of components of the program; and (c) the effects of type of documentation did not interact with the level of user's experience.
