Sociomathematical and mathematical norms related to definition in pre-service primary teachers’ discourse

This study is part of a wider research program, which seeks to investigate the existence (or not) of relationships between sociomathematical and mathematical norms at different academic levels. Here, we consider the norms that arise in the interaction between primary student teachers when they solve a mathematical task related to the mathematical definition. We hypothesize that in the colloquial mathematical discourse between these students coexist two types of discourse as follows: sociomathematical and mathematical, each one with its specific norms. This coexistence can originate commognitive conflicts. We have been able to identify different commognitive conflicts that arose from the simultaneous existence of sociomathematical norms and mathematical norms linked to defining, approaching their generation.     

Behavioral problems among children whose mothers are abused by an intimate partner

OBJECTIVES: To determine the association between children's exposure to maternal intimate partner violence (IPV) and behavior problems as measured by the parent report version of the Child Behavior Checklist (CBCL). METHODS: The study population was comprised of 167 2- to 17-year-old children of Seattle women with police-reported or court-reported intimate partner abuse. The CBCL normative population served as the comparison group. Risk of behavior problems was calculated among the exposed children, in the presence and absence of a history of reported child maltreatment, relative to the normative population. Multiple logistic regression served as the primary method of analysis. RESULTS: Children exposed to maternal IPV were more likely to have borderline to clinical level scores on externalizing (i.e., aggressive, delinquent) behavior (RR=1.6, 95% CI: 1.2, 2.1) and total behavioral problems (RR=1.4, 95% CI: 1.1, 1.9) compared to the CBCL normative sample after adjusting for age and sex. Children who were exposed to maternal IPV and were victims of child maltreatment were more likely to receive borderline to clinical level scores on internalizing (i.e., anxious, depressed) behaviors (RR=2.6, 95% CI: 1.5, 3.6), externalizing (i.e., aggressive, delinquent) behaviors (RR=3.0, 95% CI: 1.9, 4.0) and total behavioral problems (RR=2.1, 95% CI: 1.2, 3.2) compared to the CBCL normative sample after adjusting for age and sex. CONCLUSIONS: Exposure to maternal IPV is significantly associated with child behavioral problems both in the presence and absence of co-occurring child maltreatment. Appropriate attention to the mental health of children living in households with IPV is needed.     

Cost Effective Approaches to Identifying Developmental Delay in 4- to 7-Year-Old Children

Recent enactment of public laws have mandated early identification of children at risk for delayed development. Several complex assessment batteries have demonstrated satisfactory predictive and classificatory accuracy when biomedical and social-environmental measures obtained in infancy are used as predictors of later IQ scores. Yet, these complex batteries are too costly for wide- spread adoption. The present study examined the effectiveness of smaller sets of predictor variables for correctly identifying children as developmentally delayed at four through seven years of age. The results show that a combination of six biomedical risk items, maternal education level, and four subscale scores from the HOME scale are effective when used as a screening battery across a four year period. The practical implications are for this battery to be used to screen children in the preschool period for developmental delay in the early primary grades.     

Adolescents' perceptions of their fathers' involvement: Significance to school attitudes

Based on data from 2,722 British adolescents aged 14–18 years, this study explored whether perceived father involvement can be associated with school attitudes even after controlling for perceived mother involvement. Multiple regression analysis showed that both father involvement and mother involvement contributed significantly and independently to positive school attitudes. Furthermore, the association between father involvement and school attitudes was the same for sons and daughters. We did not find evidence to support the notion that being in a non‐intact family weakens the association between perceived father involvement and school attitudes. Finally, there was no evidence suggesting that the impact of perceived father involvement on school attitudes depends on the level of perceived mother involvement. © 2002, Wiley Periodicals, Inc.     

Strategies to Encourage Mathematics Learning in Early Childhood: Discussions and Brainstorming Promote Stronger Performance

This longitudinal study examined the influence of prekindergarten teacher characteristics and classroom instructional processes during mathematical activities on the growth of mathematics learning scores in prekindergarten, kindergarten, and first grade. Participants attended state-funded and Head Start prekindergarten programs. Mathematical performance was measured in fall and spring in prekindergarten and spring in kindergarten and first grade using the Test of Early Mathematics Ability–3 (TEMA-3; Ginsburg & Baroody, 2003). Two dimensions of the Classroom Assessment Scoring System (CLASS; i.e., instructional learning formats and concept development; Pianta, La Paro, & Hamre, 2008) were scored based on observed classroom mathematics activities. Teachers provided information about their education and years of prekindergarten teaching experience. Research Findings: Instructional processes that included elements of the CLASS concept development dimension, such as discussions and brainstorming to encourage children’s understanding, were related to growth of mathematics scores. Neither teacher characteristics nor instructional processes of the CLASS instructional learning formats dimension, such as using different modalities and materials, and learning objectives, were related to growth of mathematics scores. Practice or Policy: The findings extend our understandings of how instructional processes impact children’s early mathematical performance. These findings may be helpful in increasing our understanding of the types of instructional processes that might be emphasized in teacher professional development specifically related mathematical activities. Professional development that focuses on the CLASS concept development dimension may be easier for teachers to remember and implement in their classrooms and, consequently, have a greater impact on mathematics learning.     

Attitudes of high-school students taught using traditional and reform mathematics curricula in middle school: a retrospective analysis

This paper presents findings from a larger research project that provides insight into the attitudes of high-school students who were taught using different types of mathematics curricula when they were in middle school. A total of 44 12th-grade students from 10 high schools in the same urban school district were interviewed. Eighteen (41%) of them had been taught using a reform curriculum in middle school and 26 (59%) had been taught using a more traditional curriculum. Using Di Martino and Zan’s three-dimensional model for attitude, we found that the high-school seniors who had been taught using the reform curriculum in middle school harbored attitudes toward mathematics that differed significantly from the attitudes of those who had been taught using a traditional curriculum in middle school. Our analysis of the student interviews culled seven themes that provide fine-grained information about the students’ attitudes toward mathematics. Significantly greater percentages of reform students than traditional students had a relational Vision of mathematics as opposed to an instrumental Vision; however, there was no significant difference between the proportions of reform and traditional students who had a positive Emotional Disposition toward mathematics or a positive Perceived Competence in mathematics.     

Effects of tactile stimulation and gross motor movement on cognitive learning: A test of Montessori's muscular movement theory in the college classroom

Research investigating the management styles of male and female supervisors is mixed. In an effort to clarify this research, the present study examined the interaction effect of gender of supervisor and gender of subordinate on perceived mentoring. Results revealed the least amount of mentoring occurred between female supervisors and female subordinates, but the greatest mentoring took place between female supervisors and male subordinates. Results were explained in terms of managerial experience and the double‐bind of female managers. These findings challenge the traditional advice that female subordinates should seek female supervisors.
