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.     

Improving SET Response Rates: Synchronous Online Administration as a Tool to Improve Evaluation Quality

Institutions of higher education continue to migrate student evaluations of teaching (SET) from traditional, in-class paper forms to online SETs. Online SETs would favorably compare to paper-and-pencil evaluations were it not for widely reported response rate decreases that cause SET validity concerns stemming from possible nonresponse bias. To combat low response rates, one institution introduced a SET application for mobile devices and piloted formal synchronous classroom time for SET completion. This paper uses the Leverage Salience Theory to estimate the impact of these SET process changes on overall response rates, open-ended question response rates, and open end response word counts. Synchronous class time best improves SET responses when faculty encourage completion on keyboarded devices and provide students SET completion time in the first 15 min of a class meeting. Full support from administrators requires sufficient wireless signal strength, IT infrastructure, and assuring student access to devices for responses clustering around meeting times.     

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.     

Can You Go Home Again? A Phenomenological Investigation of Cypriot Students Returning Home After Studying Abroad

The goal of the present study was to describe the structure of the experience of young Cypriot students who have returned home after studying abroad. Phenomenological interviews were conducted with participants who responded to the statement: ‘`Please describe your experiences of returning home after your study abroad’’. Interviews were audio-taped, transcribed, and analyzed within the context of a research group. The emerging bipolar themes of ‘Shock/Adjustment’, ‘Freedom/Restriction’, and ‘Changing/Static’ were grounded in the theme of cultural comparison. Implications for counselling are examined.     

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.     

Constructing a Sense of Purpose and a Professional Teaching Identity: Experiences of Teacher Candidates with Disabilities

Abstract

Using grounded theory, we examined the ways in which undergraduate teacher candidates with disabilities developed a sense of purpose and constructed professional identities. Our findings suggest K-12 experiences with advocacy as well as exclusionary school experiences influenced their emerging professional identities. Resistance to a deficit view of disability was central to teachers’ professional identities and influenced their desire to become “change agents” in their future professions. We describe collegiate experiences that affirmed or presented roadblocks to their career path.     

Nonlinear Growth Mixture Models With Fractional Polynomials: An Illustration With Early Childhood Mathematics Ability

Applications of growth mixture modeling have become widespread in the fields of medicine, public health, and the social sciences for modeling linear and nonlinear patterns of change in longitudinal data with presumed heterogeneity with respect to latent group membership. However, in contrast to linear approaches, there has been relatively less focus on methods for modeling nonlinear change. We introduce a nonlinear mixture modeling approach for estimating change trajectories that rely on the use of fractional polynomials within a growth mixture modeling framework. Fractional polynomials allow for more parsimonious and flexible models in comparison to conventional polynomial models. The procedures are illustrated through the use of math ability scores obtained from 499 children over a period of 3 years, with 4 measurement occasions. Techniques for identifying the best empirically derived growth mixture model solution are also described and illustrated by way of substantive example and a simulation.     

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.
