| Abstract: | This is the second of two articles that describe the development and evaluation of three component-specific instructional systems for improving critical reading skills. The skill components that were the focus of training have been shown in prior research to represent particular sources of processing difficulty for young adult, poor readers and, based on a model of component interaction, were predicted to have a potentially strong impact on the performance of other component processes. Part 1 presented the evaluation of SPEED, a system designed to develop automaticity in the ability to perceptually encode multiletter units that appear in words. Part 2 describes the evaluation of the RACER and SKI JUMP systems, which focus respectively on developing automaticity in phonological decoding of orthographic information in words and the use of context frames in retrieving and integrating word meanings. In both the RACER and SKI JUMP training studies, all subjects achieved highly accurate and efficient levels of performance in the skill that was the focus of training. Furthermore, SKI JUMP training had an impact on word analysis components and on a measure of inferential comprehension. An analysis of the patterns of transfer of skills acquired in training is presented, and conditions for optimizing skill integration are discussed. |
