The impact of strategy instruction and timing of estimates on low and high working-memory capacity readers' absolute monitoring accuracy   总被引：2，自引：0，他引：2

Working-memory capacity, strategy instruction, and timing of estimates were investigated for their effects on absolute monitoring accuracy, which is the difference between estimated and actual reading comprehension test performance. Participants read two expository texts under one of two randomly assigned reading strategy instruction conditions (an explanation strategy versus no strategy). Next, readers estimated comprehension test performance both immediately and after a delay. Readers' estimations were followed by the completion of a comprehension test, a postdiction of test performance, and a working-memory capacity task. The results showed that low working-memory capacity readers were generally more accurate than high working-memory capacity readers but were not affected by strategy instruction or timing of estimates. In contrast, high working-memory capacity readers were most accurate when instructed to use an explanation strategy and when estimates were made immediately. These results are described in the context of the increased processing hypothesis, which contends that more effortful processing during reading augments the availability of text concepts and, in turn, enhances absolute monitoring accuracy.  相似文献   

现代远程教育中“自主”与“监控”的反思     

谢晓践 《电大教学》2008,(1):55-58

远程教育的教学模式需要学习者具有较强的自主学习能力,远程教育中的自主学习并非是孤立的,而是建立在交互与合作的基础之上的。事实上,在远程教学实践中,远程学习者自主学习能力和交互能力及水平并不理想,在坚持自主学习的同时,必须辅以适当的外在监控,才能保证远程学习的质量。  相似文献

Does visualization affect monitoring accuracy,restudy choice,and comprehension scores of students in primary education?     

《Contemporary educational psychology》2017

In the present study, we investigated how 116 fourth and fifth grade students’ monitoring skills were associated with restudy choices and explored whether drawing was a useful intervention to improve monitoring accuracy, restudy choice, and comprehension scores. During the first session, all students read a text, judged their learning of the information within that text, selected paragraphs to reread, reread those parts, and then made another judgment of learning (JOL) before doing a post-test. Several significant correlations were found between the various variables involved, such as higher JOLs before rereading related to fewer paragraphs being reread, and JOL-accuracy after rereading was positively correlated with the scores on the postreading questions. For the second session, students were split-up into three conditions: a control condition and two drawing conditions. In the long-drawing condition, students were allowed to draw throughout the whole second session, including post-test. In the brief-drawing condition participants only got to draw the first time they read the second text. We did not find significant differences on the postreading scores. The only differences we found were that the participants in the long drawing group were more accurate in their JOLs before rereading and selected more paragraphs to reread than the other two groups, and invested more mental effort in comparison to the other groups. Drawing more elements was positively correlated with the posttest scores and JOLs, whereas drawing more details was negatively correlated with posttest scores and did not correlate with JOLs. As students in the long drawing condition drew both more elements but also created more detail in those drawings compared to the short drawing condition, it is possible that the beneficial effects of creating drawings were cancelled out by the negative effects.  相似文献
