A Microanalysis of Teachers' Verbalizations in Inclusive Classrooms

The present study examined the verbalizations of 16 teachers from inclusive preschool classrooms. Two hours of audiotaped verbalizations for each teacher were analyzed for one-on-one interactions between teachers and children and also for interactions between teachers and small groups of children. Results showed that teachers did not modify their question-asking behavior depending on the ability level of the children or the composition of small groups of children. Teachers asked primarily low-level questions to all children. In their statements, teachers used more logical directives and directives, and fewer supportive responses to children with disabilities than they did to typically developing children. The focus of teachers' verbalizations differed depending on whether children had disabilities or were typically developing. These results suggest that teachers need to be provided with information that will help them challenge children by varying the demand level of questions and matching their verbalizations to the child's ability level. Future research should address the bi-directionality of interactions and the implications for teacher preparation programs.     

Toward Integration: Education,Instructional Technology,and Semiotics

It has been asserted that the boundaries of instructional technology are unclear; so, too, this author claims, are the strategies that might make them clear. He believes the boundaries can be defined when the superstructure of which the boundaries are a part is identified. In this article he advances a theoretical perspective for analyzing education and instructional technology.     

Child-mother attachment and the self in six-year-olds

Bowlby has proposed that child-parent attachment is important in the child's representation of self. In this study, the child's representation of self was examined in connection with child-mother attachment in a sample of 52 white, middle-class 6-year-olds. Children were seen in 2 play sessions, 1 month apart. Quality of attachment was assessed in each session based on the child's behavior on reunion following a laboratory separation of approximately 1 hour, using a system devised by Main and Cassidy. Aggregated attachment ratings and classifications were assigned based on the child's behavior in both reunions. Assessments of the self consisted of (a) assessment of the self within the relationship with the attachment figure (an incomplete doll stories procedure), (b) assessment of the child's perceptions of how an unspecified "other" views him or her (a puppet interview), (c) direct assessment of global self-esteem independent of the attachment relationship (the subscale of global self-esteem from Harter's Perceived Competence Scale for Children), (d) a second direct assessment of global self-esteem (an interview with the child), and (e) assessment of feelings of competence and acceptance in specific domains that may be precursors of self-esteem (Harter's Scale of Perceived Competence and Social Acceptance for Young Children). Significant, albeit modest, connections between attachment and the self were established; furthermore, specific patterns of self-perceptions were related to particular patterns of attachment.     

The effect of body composition and BMI on 25(OH)D response in vitamin D-supplemented athletes

Fat mass is inversely associated with vitamin D status, and athletes with the most adipose tissue may have the greatest risk for insufficient (25(OH)D 20–32?ng?mL^?1) or deficient (25(OH)D??1) status. The effects of fat and lean mass on 25(OH)D change in response to vitamin D supplementation have yet to be elucidated in athletes. In addition, vitamin D has a known role in bone health yet a link between short-term changes in 25(OH)D and bone turnover in indoor athletes have not yet been described. Thirty-two collegiate swimmers and divers (19 male, 13 female; 19 (1) years) participated in a 6-month randomized controlled trial and consumed either 4000?IU?d^?1 of vitamin D₃ (n?=?19) or placebo (PLA; n?=?13). Anthropometry and blood collection of 25(OH)D, bone-specific alkaline phosphatase (B-ALP) and N-terminal telopeptide (NTx) occurred at three time points. Dual-energy X-ray absorptiometry measured body composition analysis at baseline and endpoint. In the vitamin D group, BMI was negatively correlated with 6-month 25(OH)D change (R?=??0.496; P?=?.03) and a stronger predictor of 25(OH)D change (P?=?.04) than ultraviolet B exposure and fat mass change. Athletes in the high bone turnover group showed significantly greater losses of 25(OH)D over 6-months compared to athletes in the low bone turnover group (P?=?.03). These results suggest athletes within the normal BMI category experience a diminished response to 4000?IU?d^?1 of vitamin D₃ supplementation, and periods of high bone turnover may be an additional risk factor for developing compromised vitamin D status in athletes.
