CUE SYSTEM UTILIZATIONS AMONG OLDER READERS

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.

Educational change in Singapore and its ‘tinkering’ around the edges: A critical realist perspective

This article re-examines the contents of Singapore’s Thinking Schools Learning Nation (TSLN) and Teach Less Learn More (TLLM) educational initiatives, introduced and implemented to promote change and to prepare Singaporeans for a twenty-first century knowledge-based economy. Adopting a critical realist perspective that enables investigations into complex social systems, the paper highlights the concepts, change process and possible outcomes of change proposed by realist social theory. An explanatory critique responding to the question, ‘What social structural changes were implemented by the TSLN and TLLM initiatives, and why?’ is developed, tracing the programmes of change in TSLN and TLLM. Findings reported in 2013, by a local large-scale research project, has made claims about the ineffectiveness of the initiatives in bringing about desired changes in classroom instructional practices. The critique questions—given Singapore’s recent and consistent successful performances in international benchmarking tests—whether it is only in the classroom that educational change that matters, counts. It suggests that despite making strong statements about the limited effectiveness of the TSLN and TLLM initiatives, many programs introduced and adopted by primary, secondary and post-secondary institutions, especially under TLLM, were left unexamined by the research project. The explanatory critique theorises that two kinds of changes have taken place—the reorientation of pedagogical practices in post-secondary institutions and extensions of what already exists in the primary and secondary sections. The paper concludes by highlighting some implications the explanatory critique have for research into educational change in general, and for educational change in Singapore.

改变音乐节拍对脑电功率谱变异的影响及其心理意义

目的旨在探索音乐节拍对大脑活动主要区域信息加工过程中的脑电波谱变异.方法采用自编的音乐播放软件给被试分别播放(42、65、120 BPM)3种音乐节拍的65 dB音乐,每种节拍曲目播放5 min,并采集16脑区的脑电信号进行离线分析.结果 (1)与安静状态相比播放音乐时被试在7个波段的脑电波谱功率显著降低;播放音乐时脑电波谱重心频率向低频段移动,表明疲劳程度增加;(2)改变音乐节拍显著降低α1波频段的功率而增加α2波频段的功率;(3)从频段功率占比看,加快音乐节拍节奏增加高频段脑电波活动,降低节拍节奏增加低频段活动而降低高频段脑电波活动.结论音乐节拍显著影响脑电波谱功率变异,65 BPM的中等节奏音乐有利于注意力集中和放松休息,120 BPM快节奏音乐有利于激活唤醒水平,加快运动,改变音乐节拍增加注意负荷,消耗更多的心理加工资源,其意义有待于进一步探索.
