学业成绩影响儿童孤独感的中介变量分析

为考察、检验学业成绩影响儿童孤独感的中介变量,采用同伴提名问卷、依恋量表、儿童孤独感量表调查了4—6年级438名儿童。结果表明,在考察单一变量的中介作用时,亲子依恋、同伴拒绝分别在学业成绩与儿童孤独感之间起部分中介作用,教师接纳在二者之间起完全中介作用;当同时考察亲子依恋、同伴拒绝、教师接纳在学业成绩与孤独感之间的中介作用时,三种社会关系起完全中介作用。结论：教师接纳、同伴拒绝和亲子依恋是学业成绩与孤独感之间的中介变量。     

初中生社会比较在成就目标与学业自我效能感之间的中介效应

采用成就目标定向、社会比较和学业自我效能感三个量表,以724名初中生为被试,对社会比较在成就目标与学业自我效能感之间的中介作用进行了考察。结果表明：（1）除对学习能力自我效能感产生直接影响外,掌握接近目标会通过上行比较、成绩接近目标会通过上行/下行比较间接地影响学习能力自我效能感;（2）掌握接近目标、成绩接近目标和成绩回避目标不仅会对学习行为自我效能感产生直接影响,还会通过下行比较对其产生间接影响。说明成就目标可以通过直接和间接两种不同的方式影响学业自我效能感。     

An integrated theory of whole number and fractions development

This article proposes an integrated theory of acquisition of knowledge about whole numbers and fractions. Although whole numbers and fractions differ in many ways that influence their development, an important commonality is the centrality of knowledge of numerical magnitudes in overall understanding. The present findings with 11- and 13-year-olds indicate that, as with whole numbers, accuracy of fraction magnitude representations is closely related to both fractions arithmetic proficiency and overall mathematics achievement test scores, that fraction magnitude representations account for substantial variance in mathematics achievement test scores beyond that explained by fraction arithmetic proficiency, and that developing effective strategies plays a key role in improved knowledge of fractions. Theoretical and instructional implications are discussed.     

Does sensitivity to criticism mediate the relationship between theory of mind and academic achievement?

This study adds to the growing research on school outcomes associated with individual differences in preschoolers’ theory of mind skills by considering whether “costs” of theory of mind (e.g., sensitivity to criticism) actually help to foster children’s academic achievement. A group of 60 Italian children was tested during the last year of preschool (Time 1, mean age = 5 years 6 months) and in their first year (Time 2, mean age = 6 years 5 months) and second year (Time 3, mean age = 7 years 5 months) of primary school. Children’s theory of mind, verbal ability, and social skills were evaluated at each time point. In addition, children’s sensitivity to teacher criticism was assessed at Time 2 and teachers’ ratings of children’s academic achievement were gathered at Time 3. Mediation analyses showed that, independent of verbal ability and social skills, sensitivity to criticism at Time 2 mediated the association between theory of mind at Time 1 and academic achievement at Time 3. These findings highlight the importance of investigating the educational consequences of individual differences in preschoolers’ theory of mind.     

Jewish Identity and the Secular Achievements of American Jewish Men and Women

Three questions are addressed concerning the relationship of Jewish identity to secular achievements. Are the secular achievements of American Jews related at all to the strength of their Jewish identity? Which has a stronger relationship to secular achievement, a religious or an ethnic Jewish identity? Do communal aspects or private, personal aspects of Jewish identity have the stronger relationship to secular achievements? Using the 2000–2001 National Jewish Population Survey, we find that educational attainment, labor force participation, and occupational achievements are related to several expressions of Jewish identity, even after controlling for the traditional sources of variation (age, gender, education, family status). Jewish identity, as expressed in terms of religion, ethnicity, communal commitment, and private attitudes and practices, is related to contemporary Jewish secular achievement, albeit differently for men and women.     

Defective number module or impaired access? Numerical magnitude processing in first graders with mathematical difficulties

This study examined numerical magnitude processing in first graders with severe and mild forms of mathematical difficulties, children with mathematics learning disabilities (MLD) and children with low achievement (LA) in mathematics, respectively. In total, 20 children with MLD, 21 children with LA, and 41 regular achievers completed a numerical magnitude comparison task and an approximate addition task, which were presented in a symbolic and a nonsymbolic (dot arrays) format. Children with MLD and LA were impaired on tasks that involved the access of numerical magnitude information from symbolic representations, with the LA children showing a less severe performance pattern than children with MLD. They showed no deficits in accessing magnitude from underlying nonsymbolic magnitude representations. Our findings indicate that this performance pattern occurs in children from first grade onward and generalizes beyond numerical magnitude comparison tasks. These findings shed light on the types of intervention that may help children who struggle with learning mathematics.     

The Role of Childhood Neglect and Childhood Poverty in Predicting Mental Health, Academic Achievement and Crime in Adulthood

This study examines the roles of childhood neglect and childhood poverty (family and neighborhood) in predicting Posttraumatic Stress Disorder (PTSD), Major Depressive Disorder (MDD), academic achievement, and crime in young adulthood. Using existing data from a prospective cohort design study, 1,005 children with documented histories of neglect (N = 507) and matched controls (N = 497) were interviewed in young adulthood (mean age 29). Official criminal histories were also used to assess outcomes. Data were analyzed using logistic and ordinary least squares regressions and hierarchical linear modeling (HLM) to control for neighborhood clustering. Results from HLM revealed that childhood neglect and childhood family poverty uniquely predicted PTSD and adult arrest, MDD was predicted only by childhood family poverty, and a significant interaction between childhood family poverty and childhood neighborhood poverty predicted academic achievement for the control group only. Childhood neglect, childhood family poverty, and childhood neighborhood poverty each contribute to poor outcomes later in life. While interventions should be developed for neglected children to prevent negative outcomes, the current findings suggest that it is also important to consider the ecological context in which these children are growing up.     

Mental abilities and school achievement: A test of a mediation hypothesis

This study analyzes the interplay of four cognitive abilities - reasoning, divergent thinking, mental speed, and short-term memory - and their impact on academic achievement in school in a sample of adolescents in grades seven to 10 (N = 1135). Based on information processing approaches to intelligence, we tested a mediation hypothesis, which states that the complex cognitive abilities of reasoning and divergent thinking mediate the influence of the basic cognitive abilities of mental speed and short-term memory on achievement. We administered a comprehensive test battery and analyzed the data through structural equation modeling while controlling for the cluster structure of the data. Our findings support the notion that mental speed and short-term memory, as ability factors reflecting basic cognitive processes, exert an indirect influence on academic achievement by affecting reasoning and divergent thinking (total indirect effects: β = .22 and .24, respectively). Short-term memory also directly affects achievement (β = .22).     

The Big Five personality traits, learning styles, and academic achievement

Personality and learning styles are both likely to play significant roles in influencing academic achievement. College students (308 undergraduates) completed the Five Factor Inventory and the Inventory of Learning Processes and reported their grade point average. Two of the Big Five traits, conscientiousness and agreeableness, were positively related with all four learning styles (synthesis analysis, methodical study, fact retention, and elaborative processing), whereas neuroticism was negatively related with all four learning styles. In addition, extraversion and openness were positively related with elaborative processing. The Big Five together explained 14% of the variance in grade point average (GPA), and learning styles explained an additional 3%, suggesting that both personality traits and learning styles contribute to academic performance. Further, the relationship between openness and GPA was mediated by reflective learning styles (synthesis-analysis and elaborative processing). These latter results suggest that being intellectually curious fully enhances academic performance when students combine this scholarly interest with thoughtful information processing. Implications of these results are discussed in the context of teaching techniques and curriculum design.     

学校氛围与初中生学业成就:学业情绪的中介和未来取向的调节作用

采用问卷法对1243名初中生进行调查研究,考察了学业情绪在学校氛围与初中生学业成就间的中介效应,以及未来取向对这一中介过程的调节效应。结果发现,（1）在控制了性别、年级、社会经济地位后,学校氛围对学业成就具有正向预测作用;（2）积极低唤醒学业情绪和消极低唤醒学业情绪显著中介学校氛围与学业成就的关系;（3）未来取向显著调节学校氛围对初中生学业成绩的直接路径,以及通过积极低唤醒和消极低唤醒学业情绪影响学业成绩的间接路径;即学校氛围和积极低唤醒学业情绪对学业成绩的影响在低未来取向的青少年群体中更为强烈;而学校氛围对消极低唤醒学业情绪的影响在高未来取向的青少年群体中更为强烈。总之,在学校氛围影响初中生学业成就的过程中,既存在中介效应,又存在调节效应。实际干预时,可以通过改善初中生学业情绪提高初中生的学业成就,未来取向可以进一步调节该过程。
