言语与空间任务指令对数字-空间联结编码的影响

以1～9除5外的阿拉伯数字和汉字标签“左”“右”为实验材料,采用数字奇偶判断任务,探讨任务指令对数字-空间联结编码的影响。结果发现：言语任务指令条件下,词语一致性与物理一致性的交互作用显著,且词语一致和不一致时均未发现空间-数字联合反应编码效应（SNARC）,表明言语-空间编码在数字-空间联结中更有优势;空间任务指令条件下,物理一致性主效应显著,且词语一致和不一致时均出现了SNARC效应,表明视觉空间编码更有优势。说明数字-空间联结编码受实验任务指令的影响,被试会根据任务指令设置的情景选择视觉空间编码或言语-空间编码对数字进行空间联结。     

师生之间的动机感染:基于社会认知的视角

师生之间的动机感染是指在课堂情境中动机定向由教师向学生传递的过程.学生对教师行为、情绪和课堂动机气氛等线索的社会知觉是动机感染发生的基础.当前研究中,期望形成模型和教学支持模型从不同角度解释了动机感染的潜在过程.基于社会认知的视角,推测出动机感染的发生机制包含学生无意识的自动的目标感染和有意识的满足基本心理需要两条路径.该机制需要进一步验证.未来研究应关注以下几点:(1)利用质的研究方法拓展研究思路;(2)注重文化和情境等变量在动机感染中的价值;(3)动机感染双向过程的系统研究.     

图式教学对阅读理解能力、推理能力与自我效能感的影响

本研究采用自然实验法对吉林省松原市逸夫实验小学160名四、五年级的学生进行了对比实验研究,探讨图式教学对阅读理解能力、推理能力和自我效能感的影响。结果表明:(1)四、五年级实验班学生的阅读理解能力普遍提高,五年级明显。(2)仅五年级实验班学生的推理能力有了显著提高,相对而言,图式教学对五年级学生推理能力的影响要优于四年级。(3)四、五年级实验班学生的自我效能感均明显增强。这说明图式教学比常规教学更能有效地提高学生的阅读理解能力和自我效能感。     

再探外显学习指导语的作用

本研究采用加工分离程序,对外显学习指导语的作用重新加以探讨.结果发现在外显学习指导语条件下,被试的作业成绩虽然较差,但并非由于外显指导语干扰了被试对规则的掌握.事实上,外显指导语促进了被试对规则的掌握.以往有关研究之所以出现不一致的结果,是由于它们采用任务分离范式,未能有效分离外显与内隐加工,以及记忆等因素的影响.     

Effects of high-probability requests on the latency to initiate academic tasks

The purpose of this study was to evaluate the effectiveness of a high-probability request sequence on the latency to and duration of compliance to a request for completion of an independent math assignment. The participant was an elementary-school student with learning disabilities who exhibited noncompliance during math instruction. The results showed that high-probability requests were effective in reducing the latency to compliance but only minimally affected duration of engagement.     

ESTABLISHING GENERATIVE YES/NO RESPONSES IN DEVELOPMENTALLY DISABLED CHILDREN

We evaluated the effects of two procedures for teaching four developmentally disabled children to respond yes/no appropriately. During baseline, tutoring was conducted in which five known items were individually presented with the question, “Is this a_____?”, followed either by access to requested items or by remedial prompting contingent on responding. When tutoring did not improve performance, instruction was embedded in the regular classroom activities. In this condition, items requested by students were either presented or withheld on the basis of their response to the question, “Do you want ______?”. Increases in correa responding were confirmed by a multiple-baseline design across all four students and were maintained with the introduction of new items. However, generalization to “Is this a_____?” questions did not occur in the tutoring setting until specifically programmed. Subsequently, students also demonstrated appropriate yes/no responding to questions involving actions, possession, and spatial relations.     

Classroom applications of stimulus equivalence technology

We review basic concepts and methods of stimulus equivalence research and suggest applications in teaching rudimentary language arts skills in the classroom. We describe methods of establishing equivalence-based networks of matching-to-sample, writing, and naming performances. The methods may be used as a supplement to classroom instruction to assess whether standard curriculum-based approaches establish such integrated networks. Methods derived from equivalence research may be useful for remediation when traditional teaching approaches fail. Recent research suggests that direct focus on spelling performances may be required if entire networks of language arts skills are to be acquired. In addition, the equivalence relations themselves may require concentrated teaching in some children.     

知识教学中认知策略与原有知识间关系的实验研究

模拟课堂教学情境,探讨知识教学中学习者的认知策略与原有知识间的相互关系。研究表明,二者存在明显的相互作用,策略学习只有在学习者具备适当原有知识的基础上才能有效地促进学习;当原有知识缺乏时,策略教学对学习成绩没有显著性影响;原有知识水平的高低可直接影响学生的学习成绩。该结论对于实际教学工作具有一定的指导意义。     

Corrective Feedback in Oral Reading

We examined 24 studies to determine the effects on word recognition and reading comprehension of correcting errors during oral reading. Corrective feedback improved students' word reading accuracy on words in lists, and accuracy in reading words in passages. Some correction procedures had greater benefits than others. Successful error correction procedures share common characteristics, leading to recommendations about instruction: Teachers should (a) correct errors immediately; (b) require students to repeat the correct response; and (c) match correction procedure to the instructional situation and the learner. Several research recommendations are outlined.
