Instructional patterns for the teaching and learning of argumentative writing in high school English language arts classrooms

Reading and Writing - Argumentative writing has long been considered an essential skill for disciplinary learning. For researchers and curriculum developers to develop ecologically valid...     

Teaching Hypertext Composition

Composing hypertext documents can be an enriching path into the world of technical communication. In learning to produce hypertext, students are introduced to an important form of written composition that encompasses not only text generation, but also visual communication and information architecture. In this article, I provide a rationale for teaching hypertext composition and then some specific curricular suggestions in two parts, one for teaching beginners, and one for teaching more advanced students.     

Are Insecure-Avoidant Infants with Extensive Day-Care Experience Less Stressed by and More Independent in the Strange Situation?

In order to test the hypothesis that elevated ratings of avoidance and classifications of insecure-avoidant attachments of infants with extensive infant day-care histories may be the result of the fact that children with routine experiences of separation are less stressed by, and more independent in, the Strange Situation than more traditionally reared infants, 2 groups of 12-month-old infants with insecure-avoidant attachments were compared on 2 behavioral indices in each reunion-with-mother episode of the Strange Situation. 9 infants experienced less than 20 hours per week of nonparental care in their first year, and 11 infants experienced 20 or more hours of care. Contrary to propositions advanced by Clarke-Stewart, Thompson, and others, insecure-avoidant infants with extensive nonparental care experience whimpered, fussed, and cried more and engaged in object play less in each reunion episode than their insecure-avoidant counterparts with less nonparental care experience. These results are discussed in terms of the recent controversy surrounding infant day-care in the United States.     

Attachment and attention: protection in relation to gender and cumulative social-contextual adversity

Data from 918 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were examined to test the interrelation of attachment and attentional performance and 2 known risks for poor attentional performance: male gender and social-contextual adversity. Attachment was measured using the Strange Situation at 15 months, attentional performance by a Continuous Performance Test (CPT) and maternal questionnaires at 54 months, and social-contextual adversity by a variety of measures from birth to 54 months. Findings indicated (a) that children with secure attachment were less susceptible to the effects of cumulative risk and gender on CPT attentional performance than their insecure counterparts and that (b) no such differential risk susceptibility was evident for maternal reports of attention-related behavior problems.     

Predictive text entry with PAL and children with learning difficulties

Nine case studies were conducted to evaluate the usefulness of a predictive text entry program within a classroom environment. The program, PAL, was found to be very successful in eight of the cases. For children with poor motor control, the key-saving aspects speeded up text creation. Of even greater significance was the extent to which children with severe spelling problems were helped. They were able to produce much higher quality written work with a substantial reduction in the number of spelling errors. This provided great motivation for the children, and teaching staff commented on their improved confidence and attention span, as well as stimulation of language and vocabulary development. One of the children was on the verge of being classified as a non-reader and, although progress was slow, a significant improvement in the child's work was observed.     

Strategies for the Curiosity‐Driven Museum Visitor

Tracking studies show that museum visitors typically view only 20 to 40 percent of an exhibition. Current literature states that this partial use sub‐optimizes the educational benefit gained by the visitor, and that skilled visitors view an exhibition comprehensively and systematically. Contrary to that viewpoint, this paper argues that partial use of exhibitions is an intelligent and effective strategy for the visitor whose goal is to have curiosity piqued and satisfied. By using analytical approaches derived from “optimal foraging theory” in ecology, this paper demonstrates that the curiosity‐driven visitor seeks to maximize the Total Interest Value of his or her museum visit. Such visitors use a set of simple heuristics to find and focus attention only on exhibit elements with high interest value and low search costs. Their selective use of exhibit elements results in greater achievement of their own goals than would be gained by using the exhibition comprehensively.
