Making broadcast television participative: Eliciting mathematical behavior throughSquare One TV

The current reform movement in mathematics education has called for new ways of teaching that encourage children to become active participants in mathematical problem solving. In this article, the potential of educational television to elicit such behavior is investigated by reviewing research on theSquare One TV television series. A sizable body of evidence indicates that, through viewer participation,Square One TV can promote mathematical behavior directly among its target audience of 8- to 12-year-olds. Described in the article are the types of viewer participation that have been observed, threeSquare One TV formats that have consistently been found to elicit participative behavior, and several characteristics of these formats that may have been responsible for increased viewer participation. If these characteristics are incorporated into future television-based materials, they may increase the potential of the materials to elicit active participation among viewers. The production ofSquare One TV and the research described here were supported by the National Science Foundation, the Corporation for Public Broadcasting, the Carnegie Corporation, and the U.S. Department of Education. Production of the first season was also supported by the Andrew W. Mellon Foundation and by the IBM Corporation. Additional funding for the fourth and fifth seasons was provided by the Intel Corporation. This article is based on a paper presented at the 1993 meeting of the American Educational Research Association in Atlanta, Georgia.     

Working and Playing Together: Prediction of Preschool Social-Emotional Competence from Mother-Child Interaction

The impact of mother-child interaction on preschoolers' social-emotional competence was evaluated. Twenty-five girls and 23 boys (mean age = 44 mos) and their mothers were videotaped performing four play/teaching tasks. Preschool teachers completed the Baumrind Preschool Behavior Q-Sort and the Behar Problem Behavior Questionnaire. Mother-child interaction aggregates represented task orientation, positive emotion, and allowance of autonomy/reliance on mother. Results indicated that specific maternal interaction aggregates coherently predicted the children's Positive Social Behavior, Assertiveness, and Sadness in the preschool setting. Child aggregates were less effective predictors of teachers' ratings. Several gender differences in the prediction of social-emotional competence were found (e.g., maternal allowance of autonomy predicted girls' sadness, but boys' sadness was predicted by their own negative emotion). These findings' contributions to the parent-child literature are discussed.     

Improbable or impossible? How children reason about the possibility of extraordinary events

The present study investigated the development of possibility-judgment strategies between the ages of 4 and 8. In Experiment 1, 48 children and 16 adults were asked whether a variety of extraordinary events could or could not occur in real life. Although children of all ages denied the possibility of events that adults also judged impossible, children frequently denied the possibility of events that adults judged improbable but not impossible. Three additional experiments varied the manner in which possibility judgments were elicited and confirmed the robustness of preschoolers' tendency to judge improbable events impossible. Overall, it is argued that children initially mistake their inability to imagine circumstances that would allow an event to occur for evidence that no such circumstances exist.     

Families Created by Egg Donation: Parent–Child Relationship Quality in Infancy

Increasing numbers of children are being born through egg donation and thus do not share a genetic relationship with their mother. Parent–infant relationship quality was examined in 85 egg donation families and a comparison group of 65 in vitro fertilization families (infant M = 11 months). Standardized interview and observational measures were used to assess mother–infant and father–infant relationship quality at the representational and behavioral levels. Few differences were found between family types in parents’ representations of the parent–infant relationship. Differences were found between family types in the observational assessment of mother–infant relationship quality, indicating less optimal interactions in egg donation families. Findings suggest that egg donation families function well in infancy overall, but there may be subtle yet meaningful differences in mother–infant interaction quality.     

Children's Developing Descriptions and Judgments of Pretending

Two studies investigated 4- to 7-year-olds’ knowledge about pretending. In Study 1, children (N = 66) defined pretending and described examples of own and others’ pretending. In Study 2, children (N = 52) defined pretending and then completed a battery of measures that examined their understanding that pretending involved mental states. In Study 1, older children articulated more defining features of pretending than younger children. When describing how they or others pretended, children focused on action or appearance, regardless of whether they had included more defining features in their definitions of pretending. In Study 2, the more defining features children articulated, the better their performance on the battery. We discuss the implications of these data for the role of pretending in children's developing theory of mind.

Nutrition for the young athlete

Athletics is a popular sport among young people. To maintain health and optimize growth and athletic performance, young athletes need to consume an appropriate diet. Unfortunately, the dietary intake of many young athletes follows population trends rather than public health or sports nutrition recommendations. To optimize performance in some disciplines, young athletes may strive to achieve a lower body weight or body fat content and this may increase their risk for delayed growth and maturation, amenorrhoea, reduced bone density, and eating disorders. Although many of the sports nutrition principles identified for adults are similar to those for young athletes, there are some important differences. These include a higher metabolic cost of locomotion and preferential fat oxidation in young athletes during exercise. Young athletes, particularity children, are at a thermoregulatory disadvantage due to a higher surface area to weight ratio, a slower acclimatization, and lower sweating rate. An appropriate dietary intake rather than use of supplements (except when clinically indicated) is recommended to ensure young athletes participate fully and safely in athletics.     

Interjudge agreement in classifying students as learning disabled

Eighteen judges with backgrounds in assessment, decision making, and learning disabilities were asked to use an array of information to differentiate learning disabled and nonlearning disabled students. Each judge was provided with forms containing information on 42 test or subtest scores of 50 school-identified LD students and 49 non-LD students. Judges were extremely inaccurate in their classifications and in little agreement with each other. Also, it appeared that different judges emphasized different factors when making their decisions. The results suggest that, given current definitions of the condition called “learning disabilities,” there is considerable doubt that school personnel can accurately and reliably identify such students.
