Race,school choice and transfers to opportunity: implications for educational stratification in South Africa

This study investigates the links between race, school choice and educational stratification in South Africa. It focuses on racial differences in families’ efforts to take advantage of choice by transferring to opportunity (i.e., transferring to a school perceived to offer students better access to educational opportunity than their current school) and explores the implications of those transfers for emerging patterns of racial stratification in access to high quality schools. Findings reveal significant racial variation in transfers to opportunity and suggest a complex link between race and the ways in which historically disadvantaged groups have engaged with the post-apartheid educational opportunity structure.     

Technology affordances: the 'real story' in research with K-12 and undergraduate learners

Computer technologies for learning environments have been introduced with great expectations for improved learning outcomes. However, the great improvements have not materialised; some of these extant studies are examined. Of all the explanations for these disappointing results, the least examined are the affordances of the computer tools. This paper provides a rationale for studying affordances and presents two studies in K‐12 and undergraduate settings showing how powerful affordances are in affecting outcomes. Finally, the paper presents guidelines on how to gradually move students from a game affordance of a computer to a learning mode.

Will Teachers Create Opportunities for Discussion when Teaching Proof in a Geometry Classroom?

This study presents an analysis of whether geometry teachers create opportunities for student discussion when engaging students in proving as revealed through the use of a multimedia survey instrument. We presented 42 secondary mathematics teachers with 8 multimedia narratives set in the situation of doing proofs in high school geometry and asked them to choose what they would do next, presenting options that included a normative instructional action which closed off discussion and less typical actions that encouraged student discussion. Our analysis provides insight into the professional obligations that teachers use to justify their departure from the norm in order to encourage student talk as well as the background variables that are associated with such decisions. We found that while secondary mathematics teachers frequently chose to promote discussion in their classrooms, the rationale that they chose for this decision and the reasons they might choose not to immediately encourage discussion differed according to the amount of experience they had teaching geometry. We use these differences to illustrate how the professional obligations can be used to better understand how teacher decisions are rationalized at the level of the instructional situation.     

New Orleans Early Intervention Study of Children with Visual Impairments

There is widespread agreement that early intervention for children with visual impairments and their families is important and beneficial. However, few con- trolled prospective studies of the effectiveness of various types of early intervention have been completed with these children. This randomized study evaluated the immediate and long-term effects of a comprehensive, weekly homebased intervention for infants and toddlers with visual impairments, compared with a low-intensity treatment through parent group meetings offered approximately 12 times per year. In annual assessments conducted for t h e years after the intervention was begun, there were negligible statistically significant or practical differences between groups based on a variety of measures of child and family functioning. In light of the cost-effectiveness analyses reported, questions are raised about the type of early intervention that should be provided to children with visual impairments.     

The role of social comparison in students’ perceptions of ability: An enriched view of academic motivation in middle school students

This study addressed notions derived from a model by [Tesser et al., 1984] of self-concept and how it is influenced by social relationships. We were interested in whether the self-evaluation maintenance model (SEM) would allow us to investigate more directly the value component in expectancy–value models of achievement motivation. Using distinctions often made about different motivational orientations, we discovered a three-way interaction between level of mastery orientation (high or low), relevance of math (high or low), and target of rating (self or 7th grade friend) on students’ perception of ability in math. Thus, the SEM model was supported but only for students reporting a low mastery orientation. For them, those who reported math as highly relevant estimated their own ability as significantly higher than their friend’s, whereas those reporting math as less relevant showed no difference in estimates of ability between self or friend. For high mastery oriented students, no differences were found.     

Trait Understanding or Evaluative Reasoning? An Analysis of Children''s Behavioral Predictions

This study tested the hypothesis that in predicting the future behavior of an actor, older children rely on trait inferences, whereas younger children rely on global, evaluative inferences. Vignettes depicting actors engaging in trait-relevant behaviors were presented to 5- and 6-year-olds (N = 67) and 9- and 10-year-olds (N = 71). For each actor, children made predictions of future behavior, evaluated the goodness and badness of the actor, and rated each actor on a relevant trait. A mediational analysis found that the behavioral predictions of older children were mediated solely by trait ratings, whereas those of younger children were mediated by evaluative ratings. Furthermore, unlike older children, younger children made trait-like predictions only when they made an evaluation of the actor. These results suggest that young children utilize evaluative reasoning when making behavioral predictions, and therefore rely on an inferential process that is distinct from that of older children.
