Number sense or working memory? The effect of two computer-based trainings on mathematical skills in elementary school

Research on the improvement of elementary school mathematics has shown that computer-based training of number sense (e.g., processing magnitudes or locating numbers on the number line) can lead to substantial achievement gains in arithmetic skills. Recent studies, however, have highlighted that training domain-general cognitive abilities (e.g., working memory [WM]) may also improve mathematical achievement. This study addressed the question of whether a training of domain-specific number sense skills or domain-general WM abilities is more appropriate for improving mathematical abilities in elementary school. Fifty-nine children (M_age = 9 years, 32 girls and 27 boys) received either a computer-based, adaptive training of number sense (n = 20), WM skills (n = 19), or served as a control group (n = 20). The training duration was 20 min per day for 15 days. Before and after training, we measured mathematical ability using a curriculum-based math test, as well as spatial WM. For both training groups, we observed substantial increases in the math posttest compared to the control group (d = .54 for number sense skills training, d = .57 for WM training, respectively). Whereas the number sense group showed significant gains in arithmetical skills, the WM training group exhibited marginally significant gains in word problem solving. However, no training group showed significant posttest gains on the spatial WM task. Results indicate that a short training of either domain-specific or domain-general skills may result in reliable short-term training gains in math performance, although no stable training effects were found in the spatial WM task.     

Breakdown in the metacognitive chain: Good intentions aren’t enough in high school

Two experiments examined the effects of a metacognitive betting implementation in high school Biology students. The results showed that people were generally good at monitoring their own knowledge in that students performed better on items judged with high bets than items judged with low bets. We also found that those who were required to make bets, as compared to those who did not, had higher intentions of studying for longer periods of time, prior to the test. However, there were no differences in actual study time. Nor was there a difference in final performance, as one would expect, between the betters and the non-betters. In summary, we found indication of (1) good intentions when using the betting procedure, but (2) breakdown in the metacognitive chain during control. That is, while requiring students to make deliberate judgments improves their intentions to study, they, unfortunately, fail to carry out those intentions.     

初中流动儿童的内隐群体偏爱、社会支持及其对学校适应的影响

以群体偏爱的IAT测验为实验材料,结合社会支持和学校适应问卷,考察初中流动儿童在内隐群体偏爱、社会支持上与本地儿童之间的差异,并探讨这两种变量对流动儿童学校适应的影响.结果表明：（1）流动儿童存在内隐外群体偏爱,对自身所属群体表现出内隐的消极认同;本地儿童存在内隐内群体偏爱,对流动儿童具有内隐的消极认知;（2）流动儿童在父亲、教师以及同性朋友的社会支持上显著差于本地儿童;（3）在对流动儿童学校适应的影响上,社会支持的主效应显著,内隐群体偏爱和社会支持的交互作用显著;高内隐群体偏爱组中,高社会支持流动儿童的学校适应优于低社会支持儿童.     

信任倾向和面孔可信度对小学儿童信任判断的影响

该研究考察了7、9、11岁小学儿童对陌生人信任判断的发展特点,以及信任方的信任倾向和被信任方的面孔可信度在儿童信任判断中的作用特点及其发展特征。结果发现：（1）7、9、11岁小学儿童基于面孔对陌生他人进行的信任判断中,9、11岁儿童的信任水平要高于7岁儿童;（2）在信任判断中,陌生交往者的面孔可信度对7、9和11岁儿童的信任判断都具有显著的影响作用,即相对于具有不可信面孔的陌生人,儿童更愿意相信具有可信面孔的陌生人;此外,信任倾向对于信任判断的影响作用则存在一定的年龄间差异,7岁儿童的信任倾向对信任判断无影响,9和11岁儿童的信任倾向正向预测儿童对陌生人的信任水平,即相对于信任倾向低的儿童,信任倾向高的儿童对陌生人的信任水平也越高;（3）被信任方的面孔可信度在小学儿童信任判断中的影响作用要大于儿童自身的信任倾向的影响作用。这些结果表明儿童对他人的信任水平随着年龄的增长而提高;对于陌生人,小学儿童主要依据被信任方相关的可信特征线索做出相应的信任判断。     

Turning a Blind Eye: A Study of Peer Reporting in a Business School Setting

This article examines student peer reporting by extending the findings from the business ethics and higher education literature. In the conceptual model we propose that reflective moral attentiveness, subjective knowledge of the code of ethics, and academic dishonesty beliefs antecede ethical judgment of peer reporting, which impacts intentions to report peers’ unethical behavior. The relationships are tested using structural equation modeling. The findings indicate that moral attentiveness significantly influences ethical judgment, which in turn affects intention. The relationship between beliefs about academic dishonesty and ethical judgment is partially supported. Based on these results, suggestions for higher education institutions are provided.     

Contingent Resistances Methodology: Analyzing Resistance in Parents' and Daughters' Choice of an All‐Girl Middle School

Contemporary perspectives on dominance and resistance as multifaceted and dialogical call for a similarly dialogical methodology, as reflected in Saukko's concept of contingent resistances. Compared to much of the past resistance research, contingent resistances sets forth an expanded vision of dialogicality in research design and in the interpretation of actor's meanings. Our purpose is to illustrate three implications of this methodology: (i) polyvocality—a comparison of perspectives of two groups of actors; (ii) consideration of the full range of meanings relevant to the action with particular attention to reactions from the local context; and (iii) interpretations of resistance that are firmly grounded in narrators' meanings. The analysis is based on interviews with parents and their young adolescent daughters about their decision to attend a new all‐girl college‐preparatory public school located in southwestern USA. Expanding on past studies of girls' school choice, we show how parents and daughters create different meanings of this decision, largely based on interactions with their peers. Although both parents and daughters emphasized academic opportunity as their main reason for the school choice, daughters, unlike parents, were confronted with violating peer femininity/heteronormativity norms. Thus, the decision required resistance on the part of daughters in a way that it did not for parents. We view contingent resistances as a useful methodological framework in a range of areas where questions of resistance are at stake. Copyright © 2013 John Wiley & Sons, Ltd.     

Personality traits measured at baseline can predict academic performance in upper secondary school three years late

The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three‐year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, 1992 ) – particularly Conscientiousness and Neuroticism – were found to predict overall academic performance, after controlling for general intelligence. Results suggest that Conscientiousness, as measured at the age of 16, can explain change in academic performance at the age of 19. The effect of Neuroticism on Conscientiousness indicates that, as regarding getting good grades, it is better to be a bit neurotic than to be stable. The study extends previous work by assessing the relationship between the Big Five and academic performance over a three‐year period. The results offer educators avenues for improving educational achievement.     

Daily Behavior Report Cards with and without Home-Based Consequences: Improving Classroom Behavior in Low Income,African American Children with ADHD

Daily Behavior Report Cards (DBRC), which typically require teachers to evaluate students' daily behavior and parents to provide contingent consequences, are an effective and acceptable method for improving children's classroom behavior. The current study evaluated whether parent involvement is an essential treatment component or whether teacher feedback alone would be sufficient to produce children's behavior changes. The effectiveness of DBRC with teacher feedback to students and parent delivered consequences (PC) was compared to teacher feedback to students only (no parent delivered consequences, NPC) for increasing appropriate classroom behavior and academic productivity in African American, low income, elementary school children with Attention-Deficit/Hyperactivity Disorder (ADHD). Both treatments led to increased on-task behavior, although PC was superior to NPC. Academic productivity outcomes are less clear. Treatment implications and future directions for research on teacher feedback interventions are discussed.     

Comparative Effects and Social Validation of Support Strategies to Promote Mindfulness Practices Among High School Students

Abstract

We compared the effects of support strategies for promoting formal mindfulness practices of 9th grade high school students who participated in a 10-week school-based mindfulness education program. The students also completed social validity ratings of the support strategies they selected and the formal mindfulness practices they learned. All of the support strategies were associated with increased average minutes of formal mindfulness practices. Students who did not select an extra support strategy also had increased minutes of formal mindfulness practices but of less magnitude in contrast to the two most effective strategies. The social validity ratings of the support strategies ranged from equivocal to good approval, and the students gave positive ratings to the majority of formal mindfulness practices. We discuss the implications of these findings for designing mindfulness education programs, implementing practice-promoting support strategies, and conducting mindfulness research with school children and youth.
