大学生的阅读理解监控,阅读理解成绩及其相关因素

该研究选取90名大学生为被试,探索了阅读理解监控,阅读理解成绩及其相关因素。结果发现:大学生的阅读广度,阅读理解效能感和对所阅读材料的熟悉程度对其理解监控水平具有直接的影响作用;大学生的阅读理解监控,阅读广度和阅读材料的难度对其阅读理解成绩具有直接的影响作用;阅读广度同时经由阅读理解监控进而对阅读理解成绩具有间接影响作用。     

背景音乐对中学生阅读理解的影响

以初一、初二、高一、高二72名中学生为研究对象,考察不同类型音乐对有无背景音乐偏好被试阅读理解成绩的影响。实验结果表明:(1)不同类型背景音乐对不同年级被试产生了不同的影响。古典乐对4个年级被试的阅读理解均有显著的促进作用;而流行乐对初中生的阅读理解产生了干扰作用,对高中生则没有产生干扰作用。(2)不同类型背景音乐对不同背景音乐偏好被试产生了不同的影响。对有背景音乐偏好被试来讲,古典乐对他们的阅读理解有显著的促进作用,流行乐对他们的阅读理解无显著的干扰作用;对无背景音乐偏好被试来讲,古典乐对他们的阅读理解既无显著的促进作用,也无显著的干扰作用,而流行乐对他们的阅读理解有显著的干扰作用。     

语文学困生与学优生阅读理解监控的发展研究

本研究采用错误检测法和理解自信度评价法,以错误觉察人数、错误觉察成绩、理解自信度评价成绩、阅读时间和阅读理解成绩为分析指标,探讨了不同年级语文学困生与学优生的阅读理解监控特征。结果发现:(1)语文学困生的阅读理解监控能力明显低于学优生;(2)学生对低难度错误信息的理解监控能力明显高于对高难度错误信息的理解监控;(3)随着年级的增长,学生的阅读理解监控能力也随之提高。     

文本阅读中的信息整合研究

文本阅读中的信息整合研究是当前文本阅读研究的热点问题,在这一问题上,虽然当前研究已经达成了一些基本共识,但仍然存在着建构主义理论、最低限度假设和记忆基础文本加工理论这三种理论争议。本文详细介绍了这三种理论争议的主要观点和实验证据,特别是重点分析了三种理论争议的最新发展,在此基础上对未来的研究趋势进行了展望。     

Effects of Self-Monitoring on On-Task Behaviors of At-Risk Middle School Students

The purposes of this study were to evaluate the effects of self-monitoring on increasing the on-task behaviors of four at-risk middle school students, and to examine its indirect effects on academic performance. Additionally, we attempted to develop and validate cost- and time-efficient procedures that typical classroom teachers could use. The data from a multiple baseline design across three academic settings, replicated with four students, revealed immediate increases in on-task behavior as each student began to self-monitor in each sequential setting. The data also revealed slightly higher levels of academic performance and, in most instances, gradually accelerating trends. These findings suggest that self-monitoring is a cost- and time-efficient procedure that classroom teachers can use to teach at-risk students to manage their own behaviors.     

Ethical issues in graduate education

Concern about the employment prospects of Ph.D.’s in the sciences and engineering has prompted overdue interest in the ethical aspects of graduate education. It is not possible to isolate an ethical inquiry that focuses solely on job-related issues. The ethical problems in graduate education are each related to employment, but none is related to employment only. We can illuminate potential ethical problems by considering conflicts of interest at each point from the decision to offer a graduate program through the treatment of its alumni. Such consideration prompts reassessment of program content, relations with students, and the objectives of graduate programs. This paper is a revised and expanded version of a presentation given at the American Association for the Advancement of Science meeting in Seattle, WA, February, 1997, during a program organized by the National Science Foundation (“Ethics, Employment, and Graduate Education in Science and Engineering,” Rachelle Hollander, Organizer).

USING NUMBER LINE PROCEDURES AND PEER TUTORING TO IMPROVE THE MATHEMATICS COMPUTATION OF LOW-PERFORMING FIRST GRADERS

Recommendations for mathematics instruction frequently include the use of manipulatives as a critical component. There are few experimental analyses of teaching strategies involving the use of manipulatives (e.g., the number line). This investigation used a multiple baseline design across three groups of students to examine the effectiveness of an experimental procedure for improving low-performing children's skills in solving missing addend arithmetic problems using the number line. To address concerns about inadequate time for instruction and insufficient practice in most mathematics instruction, trained peer tutors implemented the procedure. The results suggest that student performance improved when trained tutors taught the students number line procedures and gave them feedback on accuracy. Further, social validation data indicate that the students, their tutors, and their classroom teachers liked the procedures.     

Resurgence of derived stimulus relations.

Resurgence has been shown in human and nonhuman operant behavior, but not in derived relational responses. The present study examined this issue. Twenty-three undergraduates were trained to make conditional discriminations in a three-choice matching-to-sample paradigm. The training resulted in three equivalence classes, each consisting of four arbitrarily configured visual stimuli. The same 12 stimuli were then reorganized, and the conditional discrimination training was repeated such that three new classes were possible. In a subsequent test of derived relations, most subjects showed response patterns that were consistent with the altered conditional discriminations. Subjects were then exposed to conditional discrimination trials under extinction. Most subjects continued to respond consistently with the most recently reinforced conditional discrimination trials. During the next phase, subjects were exposed to symmetry and equivalence trials. Responses consistent with the most recent training produced feedback saying that the responses were incorrect, whereas other responses produced no feedback. Most subjects showed a resurgence of responding that was consistent with their earlier training. Finally, subjects were exposed to conditional discrimination trials carried out in extinction. Most subjects continued to show a resurgence of responding that was consistent with their early training.     

中小学生智力发展的脑电图研究

利用脑ET技术对认知功能正常的被试进行智力发展的脑电图研究。结果表明:(1)随着年龄的增长,小学生脑α波的平均频率呈明显的上升趋势,而中学生的变化幅度不大,但明显超过60年代的同期水平;(2)脑波平均频率的空间分布表现出额低枕高的前后梯度,在年龄低组被试有逆转现象,随年龄的增长,逆转现象减少,大脑的有序程度逐渐增强;(3)小学生的信息加工速度与脑α波的关系并不十分明显,而其脑波频率的分布和发展特点与计算速度有着根本的联系。中学生的表象能力与不同脑区平均频率的关系因年龄不同而有所差异,主要表现为在右顶叶、右前颞叶、右后颞叶和左后颞叶区域,表象能力好组频率大于差组。
