Elementary Extensions of External Classes in a Nonstandard Universe

In continuation of our study of HST, Hrbaek set theory (a nonstandard set theory which includes, in particular, the ZFC Replacement and Separation schemata in the st--language, and Saturation for well-orderable families of internal sets), we consider the problem of existence of elementary extensions of inner "external" subclasses of the HST universe.We show that, given a standard cardinal , any set R * generates an "internal" class S(R) of all sets standard relatively to elements of R, and an "external" class L[S(R)] of all sets constructible (in a sense close to the Gödel constructibility) from sets in S(R). We prove that under some mild saturation-like requirements for R the class L[S(R)] models a certain -version of HST including the principle of +-saturation; moreover, in this case L[S(R)] is an elementary extension of L[S(R)] in the st--language whenever sets R R satisfy the requirements.     

Effects of Self-Monitoring on the On-Task Behavior and Written Language Performance of Elementary Students with Learning Disabilities

The present study was conducted to determine the effects of self-monitoring and a changing criterion with public posting phase on student on-task behavior and written language performance. Four elementary school boys participated and were enrolled in an urban-based, elementary-level resource room for students with learning disabilities. Self-monitoring procedures for on-task behavior included the students listening to a tone recorded at 60-s intervals and responding to the question, “Am I on-task?” Written language performance involved the students writing for a 10-min. session and counting and graphing the number of words written. During baseline conditions, student on-task behavior and written language performance were collected. During the self-monitoring conditions, the students monitored their on-task behavior and written language performance simultaneously. In the changing criterion with public posting condition, the students received their goal for the day's session prior to writing, wrote, and recorded whether they met their goal. While the results show a functional relationship between self-monitoring and on-task behavior, the data for the relationship between self-monitoring and written language performance were less compelling. A greater increase occurred when the changing criterion with public posting condition was introduced. Results suggest that self-monitoring changed on-task behavior; however, further research needs to be conducted to determine the conditions that would produce comparable effects for written language performance. Several implications for students and teachers and parent training were discussed.     

Social disadvantage and neglectful parenting as precursors to the development of antisocial and aggressive child behavior: Testing a theoretical model

The present study tested a theoretical model advanced to understand the direct and mediated effects of social disadvantage, neglectful parenting, and punitive parenting in the developmental trajectory of aggressive and antisocial behavior in young school‐aged children. To test the model, families of 310 first grade children and 361 fifth grade children, participating in a universal prevention trial in high‐risk areas of a medium‐sized metropolitan area, provided data. Multi‐method and multi‐source indices of the four predictive constructs (Social Disadvantage, Denial of Care Neglect, Supervisory Neglect, and Punitive Discipline) were obtained at the time of enrollment. Multi‐method and multi‐source indices of the criterion construct (Aggression and Antisocial Behavior) were obtained at the time of enrollment and at a five year follow‐up. Based on structural equation modeling, the results established care neglect as a mediator of social disadvantage, and the importance of care neglect to both punitive discipline and antisocial outcomes in the first‐ and fifth‐grade cohorts. Supervisory neglect, however, was important in the antisocial outcome of the fifth‐grade cohort only. Overall, the results established the importance of distinguishing between two subtypes of neglect and the need to consider the role of discipline in concert with neglect when attempting to understand the impact of parenting on the development of antisocial behavior.

家长投入对中小学生学业投入的影响:有中介的调节模型

以北京市12所中小学的4160名学生为调查对象,采用层次回归方法考察了家长投入对子女学业投入的影响以及家长自主支持/控制的教养风格和子女的学业心理需要满足在其中的作用。结果发现:(1)中小学生的家长投入程度随学段升高而降低;(2)家长注重在家辅导方面的投入,在参与社区及学校活动等方面的投入较为欠缺;(3)家长投入对子女的学业投入具有显著的正向预测作用;(4)家长自主支持/控制的教养风格在家长投入与子女学业投入的关系中起调节作用,且该调节效应部分地通过子女的学业心理需要满足这一中介变量产生作用。     

小学生创造性科学问题提出能力的发展研究

运用实验的方法,对371名小学生创造性科学问题提出能力的发展进行了研究。结果表明:(1)小学生创造性科学问题提出能力整体呈上升趋势;(2)男女生的创造性科学问题提出能力发展趋势基本相同,男生整体上要略高于女生,差异不显著;(3)小学生创造性科学问题提出能力的学校类型差异主要表现在发展趋势上,城市小学二到三年级停滞不前,乡村小学则迅速发展,之后发展趋势相同;(4)三到四年级是小学生创造性科学问题提出能力发展的“关键期”。     

Development of the Japanese Version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES-J)1,2

The purpose of this study was to develop and validate a Japanese version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES), which assesses enjoyment, anxiety, and boredom experienced by elementary school students within the settings of attending class, doing homework, and taking tests. Japanese elementary school students (n = 863 for the first survey; n = 332 for the second survey) participated in the questionnaire survey. The results showed that the psychometric properties of the Japanese AEQ-ES were comparable to those of the original version. Moreover, the results showed that students' achievement emotions were associated with their control and value appraisals, as well as their academic motivation, learning strategies, academic performance, and support from teachers. These results indicated that the Japanese version of the AEQ-ES was a good measure of elementary school students' emotions and supported the propositions of the control–value theory of achievement emotions.     

四川地震灾后中小学教师心理创伤评估报告

课题研究组对四川地震灾后重灾区和极重灾区的631名中小学教师创伤后应激障碍（PTSD）进行了调查,调查后对统计结果分析表明：（1）有PTSD重度症状表现的教师为18.7%;（2）极重灾区教师创伤显著高于重灾区教师;（3）青年教师的创伤要高于年长教师;（4）地震后部分教师感到内疚,无助,压抑,无信心,生命无意义,他们成为PTSD症状的易感人群     

简算策略教学提高小学四年级儿童的计算水平及延迟效应

采用3组平衡组实验设计对小学四年级171名学生进行教学实验,两组实验班学生分别采用讲授式和探究式教学方法进行简算策略计算教学,对照班教师自主进行计算教学。结果揭示：通过专门开设简算策略教学训练课,实验班学生的的计算成绩、计算速度和计算兴趣显著高于对照班学生;实验班的延迟提示与不提示测验无显著差异,未出现策略“利用性缺陷”现象;讲授式和探究式教学方法进行策略教学的效果无明显差异。本研究表明：专门开设策略训练课能提高学生的计算水平和学习兴趣,是有效的和必要的;只要教学方法得当,策略“利用性缺陷”可以避免     

中小学生的情绪表达方式认知及其与同伴接纳的关系

本研究采用D.Matsumoto等编制的情绪表达规则评估问卷,探讨了237名中小学生情绪表达方式的认知发展,并通过同伴提名法选择了192名同伴关系良好和同伴关系不良的中学生为被试,探讨了情绪表达方式认知与同伴接纳的关系。结果表明:情绪类型与情境类型对中小学生多种情绪表达方式的认知具有主效应;中小学生的情绪表达向更具有社会效益方向发展,对自我和他人情绪表达存在认识分化,并随年龄而增加;同伴关系不良的中学生在情绪表达的认知上存在发展滞后。     

小学儿童假设检验思维策略的发展

采用自创的“固定样例”程序,利用自行设计的两种不同任务的图形推理材料,研究了小学儿童假设检验策略的发展。550名不同年级的被试参加了本研究：结果发现,在该研究条件下：(1)答案存在多种可能性的任务Ⅰ明显难于答案确定的任务Ⅱ;(2)小学儿童假设检验能力随年级提高而增长,但增长的速度因任务不同而不同;(3)随着年级的提高,小学儿童使用的不成功策略逐步下降,成功策略显著上升,但这也受任务不同的影响;(4)固定样例程序较好地克服了变化样例程序所带来的假设检验研究的缺陷。
