The effects of writing style upon mature older readers’ reading comprehension are considered. Two narrative historical selections, the first emotive and abstract and the second nonemotive and concrete, were employed. Miscue analysis was used to evaluate the efficiency with which each reader used reading strategies across the five systems that cue meaningful comprehension. Miscues were analyzed at the word, clause, sentence, and intersentence levels. In addition, interview schedules were employed to identify readers’ perceptions of preferred reading strategies and to permit a comparison with actual performance. The findings indicate that mature older readers are consistent in cue system utilization. A preference for the word cue system influenced both the use of cues from other systems and comprehension. Use of the word‐level cue system is inversely related to the use of the other available cue systems. Preference for cues within words also appears to be inversely related to comprehending effectiveness. The subjects’ perceptions of the reading process and their actual reading performance appeared to determine patterns of cue system use more clearly than did the differences in materials. As a result, those developing materials intended for use in programs with older persons should not only be concerned with the content and quality of those materials but also the skills and perceptions of those who will use the materials.  相似文献

Abstract

The Florida Teletraining Project tested the feasibility of using community colleges as providers of various types of military training to personnel in the Reserve Components (RC). Training was delivered via the Army's TNET system, which employs two‐way interactive video. Five courses were produced, delivered, and evaluated during the project. Results showed that effective military course reconfiguration can be accomplished by civilian institutions, that the delivery system was technically reliable, that students performed well using specially reconfigured courseware, and that students rated the video teletraining approach as effective. The project demonstrated the potential of two‐way video teletraining for a variety of military training applications for several different levels of military personnel.  相似文献

The paper provides (1) a teacher-administered rating instrument for inattention without confounding the rating with hyperactivity and conduct disorder, and (2) evidence that the ratings correlate with the scores obtained from cognitive tests of attention. In Study I, the first objective was to investigate the construct validity and the inter-rater reliability of the Attention Checklist (ACL) by factor analysing the teacher ratings of 110 Grade 4 children, obtained by using the ACL. The second objective was to investigate the predictive validity of the ACL by examining the relationship between the scores obtained for the participants from teachers' ratings using the ACL and the scores obtained by participants in the lab-type attention tests. The results of factor analysis showed that a single factor labelled ‘inattention’ underlies the 12 items in the ACL. Examining the differences in performance on attention tests, the ‘low attention’ children as rated by the teachers on the ACL scored lower than the ‘high attention’ children on the objective tests of attention. These findings were replicated in Study II, which was conducted to test further the construct validity and predictive validity of the ACL. This time, only those two tests (Auditory Attention and Visual Attention) that had shown relatively poor discrimination between the high and low attention groups in Study I were, again, administered to another cohort of 97 Grade 4 children, as it was our intention to further challenge the reliability of the ACL. Overall, the results of both studies suggest that comprehensive assessment of attention skills should include both ACL and objective measures of selective attention.  相似文献
