小学2-4年级儿童数学应用题表征策略对其解决不规则问题影响的研究

本研究运用实验法和临床访谈法对某普通小学的123名2-4年级学生进行了不规则数学应用题测验,以考察数学学优生和学差生在解决这些应用题时表征策略的差异。结果表明：（1）从2-4年级儿童解答条件多余和条件不足应用题上看,学优生的成绩要好于学差生,口头报告分析显示学优生较多地使用问题模型策略对问题进行表征,而学差生较多使用直接转换策略对问题进行表征;（2）在三年级时,条件多余和条件不足应用题的解题正确率有所提高,但到四年级时,正确率却有所下降;（3）在解决条件多余和条件不足应用题中,性别差异不显著。     

学校心理环境对小学4～6年级学生学业表现的作用及条件

本研究基于具有良好全国代表性的中国儿童青少年心理发育特征数据库,使用多水平建模,分析了来自全国100个区县421所学校的心理环境特征对10826名小学4~6年级学生学业表现的影响途径及其发挥作用的条件。研究结果表明:(1)小学4~6年级学生学习动机和态度及学业成绩中分别有10.0%和33.3%的变异来自学生个体以外的学校因素。(2)在控制学生年级、性别、家庭背景和学校所在地、师资、学校学生总体家庭社会经济地位(SES)等基本特征后,学校总体和学生个体知觉两个层次的学校心理环境对学生学习动机和态度的影响均显著大于其对学生学业成绩的影响;与个体知觉到的心理环境相比,学校总体心理环境对学生学业成绩的作用相对较强。(3)学校总体心理环境对学生学业表现的影响受到学校所在地、学校师资水平、学校学生总体社会经济地位的显著调节。学校总体心理环境对处于师资水平较低、平均家庭年收入较低学校学生的学习动机和态度具有相对更强的保护作用;对处于农村、师资水平较低、平均家长文化水平较低学校学生的学业成绩具有相对更强的保护性作用。上述结果表明,学校总体心理环境对学生学业表现具有重要影响,个体知觉到的心理环境仅部分中介其作用;且学校总体心理环境对学生学业表现的作用强度受到学校所在地、师资水平和学校学生总体社会经济地位的调节。     

Decomposition of a Rasch partial credit item into independent binary and indecomposable trinary items

For each Rasch (Masters) partial credit item, there exists a set of independent Rasch binary and indecomposable trinary items for which the sum of the scores and the partial credit score have identical probability density functions. If each indecomposable trinary item is further expressed as the sum of two binary items, then the binary items are positively dependent and cannot be both of the Rasch type. This paper was written while the author was working with Steve Ferrara and Hillary Michaels on some technical aspects of the Maryland School Performance Assessment Program. The author had been puzzled by the fact that most MSPAP assessment items have three or less score categories. With a psychometric justification now being apparent, this paper is dedicated to both of them.     

Effects of sequential 1-minute time trials with and without inter-trial feedback and self-correction on general and special education students' fluency with math facts

We measured the effects of two procedures for implementing 1-min time trials on the rate and accuracy with which elementary students wrote answers to single-digit math facts in two concurrent experiments in a first grade classroom and a special education classroom. On-task behavior of three students in each class was also measured. Baseline was a 10-min work period in which students were told to answer as many problems as you can. The two time trial conditions, each of which was also conducted within a 10-min period, consisted of: (1) a series of seven 1-min time trials with a 20-s rest period following each timing; and (2) two 1-min timings, each followed by a teacher-directed feedback and self-correction activity. Students in both classrooms answered correctly more problems per minute during both time trial conditions than they did during the 10-min work period, with the highest levels of fluency occurring during the two time trials with self-correction. The emphasis on going fast did not impair students' accuracy of performance. In both classrooms the percentage of attempted problems answered correctly was high during the initial baseline and increased slightly over the course of the study. On-task behavior was higher during both time trial conditions than during the 10-min work period. When asked at the study's conclusion which of the three methods for practicing math facts (1) helped you learn the most and (2) would you like to do again, the majority of the students in both classrooms chose the time trials followed by feedback and self-correction.     

Mentoring to prevent school drop outs

American businesses have established partnerships with schools in an effort to upgrade the quality of education and increase the number of skilled workers for the future. In these partnerships, business employees act as mentors to help develop human and social capital in at-risk children beginning at an early age so that they will graduate from high school and be prepared for post-secondary education. The purpose of this study was to examine mentoring policy in two elementary schools in an urban district. Participants in the study included central office administrators, principals from the two schools, 10 fourth-grade at-risk students in each school who had been mentored for at least one year, their mentors from local businesses, their teachers, and parents. Data were gathered from interviews, documents, and observations. The successes and limitations for mentoring programs in these two schools depended on policy, implementation, school governance, and support from central office. The study provided implications for improving these programs and providing a model for future mentoring programs.     

提高小学四年级学生情绪胜任力的干预研究

基于将情绪、认知和行为发展相整合的理念,试图通过团体干预活动,提高小学生的情绪胜任力。结果表明,6个系列干预活动能够有效提高小学四年级学生的情绪词汇量、情绪识别能力和情绪调节能力。团体内同伴提名和教师访谈显示,干预活动有助于促进学生的积极心境、自我控制能力和亲社会社交能力的发展,有助于减少攻击、同伴拒绝等适应不良行为。     

Maternal Perceptions of Competence and Children’s Academic Adjustment: Longitudinal Relations across Early Elementary School

Children’s perceptions of their academic ability play an important role in their academic adjustment, but relatively little research has examined the factors affecting academic self perceptions of young children, especially the role of parents. Seventy-seven children and their mothers were followed longitudinally from kindergarten to fourth grade to assess the association between mothers’ early perceptions of children’s academic abilities in reading and math and children’s later academic adjustment. Mothers’ perceptions of children’s reading ability in kindergarten were associated with children’s later self-perceptions of academic competence and later achievement, above and beyond kindergarten achievement. However, mothers’ perceptions of math ability in kindergarten were not significantly associated with later outcomes. In reading, mothers’ perceptions of children’s natural talent were positively associated with later self-perceptions and mothers’ perceptions of children’s difficulty in school were negatively associated with later self-perceptions. Additionally, mothers’ perceptions of children’s reading competence were positively associated with later reading achievement. This was the youngest sample in which these relations have been examined to date. Longer-term implications for early parental perceptions are discussed.     

Relations between different types of children's aggressive behavior and sociometric status among peers of the same and opposite gender

Croatian elementary school children in grades 4 to 6 (N= 151) reported on direct and indirect aggressive behaviors of their classmates. Acceptance and rejection by classmates were also assessed, employing the sociometric nomination technique. Correlational analyses revealed that both forms of aggression were related to peer rejection, but unrelated to peer acceptance. Girls' aggression was more strongly related to peer rejection than boys' aggression, independent of the type of aggression. Aggressive children of both genders tended to be more rejected by their same-gender classmates than by classmates of the opposite gender. Results were discussed in terms of children's attitudes towards aggression, and gender stereotyped perception of appropriateness of aggressive behavior. A need to examine developmental changes and cultural differences in relationships between aggression and peer status was emphasized.
