Cognitive characteristics of children with mathematics learning disability (MLD) vary as a function of the cutoff criterion used to define MLD

Researchers of mathematics learning disability (MLD) commonly use cutoff scores to determine which participants have MLD. Some researchers apply more restrictive cutoffs than others (e.g., performance below the 10th vs. below the 35th percentile). Different cutoffs may lead to groups of children that differ in their profile of math and related skills, including reading, visual-spatial, and working memory skills. The present study assesses the characteristics of children with MLD based on varying MLD definitions of math performance either below the 10th percentile (n = 22) or between the 11th and 25th percentile (n = 42) on the Test of Early Math Ability, second edition (TEMA-2). Initial starting levels and growth rates for math and related skills were examined in these two MLD groups relative to a comparison group (n = 146) whose TEMA-2 performance exceeded the 25th percentile. Between kindergarten and third grade, differences emerged in the starting level and growth rate, suggesting qualitative differences among the three groups. Despite some similarities, qualitative group differences were also observed in the profiles of math-related skills across groups. These results highlight differences in student characteristics based on the definition of MLD and illustrate the value of examining skill areas associated with math performance in addition to math performance itself.     

Practicing What We Teach: A Self-Study in Implementing an Inquiry-Based Curriculum in a Middle Grades Classroom

A science teacher educator returned to teaching adolescents after more than 10 years in the professoriate. We studied his beliefs, practice and daily use of inquiry pedagogy while implementing a reform-based curriculum. Reflection on practice was evidenced by a weekly journal, classroom observations and debriefings, and extensive interviews. Newly developed practical knowledge from this experience shifted the science teacher educator’s beliefs away from the Piagetian structuralism espoused in prescribed curricula towards a more culturally responsive, student-driven approach to teaching science to middle grades students. The merits and limitations of curricula attempting to follow traditional scientific practices are discussed.     

Beyond the Black–White Test Score Gap: Latinos’ Early School Experiences and Literacy Outcomes

Data from the Early Childhood Longitudinal Survey–Birth Cohort are used to analyze the factors that lead to the reading readiness of children who participate in nonparental care the year prior to kindergarten (N = 4,550), with a specific focus on Latino children (N = 800). Stepwise multiple linear regression analysis demonstrates that reading scores are significantly influenced by the type of care provided the year prior to kindergarten, the caregiver’s education and beliefs about kindergarten readiness, as well as access to books and a computer in the home. Furthermore, mother’s level of education and marital status are important predictors of reading aptitude.     

The Improvement of Mothers’ and Children’s Emotional and Behavioral Reactions through the Modification of Attentional Bias in Mothers: A Micro-Trial Study

Objective. The aim of this study was to test whether and to what extent inducing attentional bias in mothers toward a child’s positive emotions using a micro-trial method would improve mothers’ emotional and behavioral reactions in parenting-related situations. Effects on children were also assessed. Design. Forty-two mothers of 4- to 5-year-old children participated. Half of the mothers were exposed to an attention bias modification task designed to elicit a transient bias toward positive stimuli. After the manipulation, they were observed during a free-play session and frustration laboratory tasks designed to elicit positive and negative emotions. Results. Mothers exposed to the attention bias modification task displayed more positive emotional and behavioral reactions toward their child during both free-play and frustration tasks. Their children also behaved better, especially during the free-play session. The influence of mothers’ attention allocation on children’s outcomes was mediated by mothers’ behavior. Conclusions. An attention bias modification program is useful in improving interactions between mothers and children.     

Examining Teachers' Hurdles to ‘Science for All’

The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed.     

Children's Understanding of Parental Differential Treatment

This study examined whether established associations between perceptions of parental differential treatment and sibling relationship quality are moderated by children's perceptions and attributions about parental behavior. Sixty-one children, aged 11–13 years, and their siblings were interviewed separately about parental differential treatment. Children did not perceive PDT in two-thirds of the instances they reported about, and 75% of the children who acknowledged that differential treatment was occurring in their homes did not find this to be " unfair." Children justified differential parental behaviors by identifying ways that they and their sibling differ from one another, that is, in terms of differences in their age, personal attributes, needs, relationship with parents, or strategic behaviors. Children who perceived their parents' differential behavior to be justified generally experienced more positive appraisals about their sibling relationship. Results reinforce the importance of examining how children construct their experiences in their families.
