The Choice of Response Probability in Bookmark Standard Setting: An Experimental Study

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the resulting judgments. This article presents the results of an experiment in which content experts were randomly assigned to one of two response probability conditions: .67 and .80. If the standard-setting judgments collected with the bookmark procedure are internally consistent, both conditions should produce highly similar cut scores. The results showed substantially different cut scores for the two conditions; this calls into question whether content experts can produce the type of internally consistent judgments that are required using the bookmark procedure.     

Data in Motion: Sports as a site for expansive learning

ABSTRACT

Background and Context

Sports and technology are often pitted as being at odds with one another. While there are several educational activities that make reference to sports we seldom see sports used as an authentic context for learning computing.     

Improving the reading skills of young people with Duchenne muscular dystrophy in preparation for adulthood

Duchenne muscular dystrophy (DMD) is a progressive genetic condition that affects both muscle and brain. Children with DMD are at risk of psycho‐social difficulties such as poor academic achievement and behavioural and socio‐emotional problems. This article by Janet Hoskin and Angela Fawcett, both from the University of Swansea, describes how 34 participants with DMD took part in a 36‐week online literacy intervention which was delivered in partnership between home and school. The key objective was to improve reading skill. Participants were re‐tested at 36 weeks for single word and text level reading, comprehension, fluency, processing and timed single word reading. Pre and post results indicated that children who followed the intervention for 36 weeks made significant improvement in their single word reading (p = <0.0001), timed single word reading (p = <0.0001) and text level reading (p = <0.004). They also made significant improvement in their fluency and comprehension scores. The results showed that children with DMD and related literacy difficulties benefit from a regular, structured and systematic synthetic phonics programme. With young people with DMD increasingly living into adulthood, early literacy intervention is particularly important to ensure optimum career and training opportunities.     

Depression and Anxiety in the Postnatal Period: An Examination of Infants’ Home Language Environment,Vocalizations, and Expressive Language Abilities

This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability.     

College Drinkers’ Privacy Management of Alcohol Content on Social-Networking Sites

Alcohol-related posts on social-networking sites (SNS) can damage college students’ reputations and relationships and contribute to risky behavior. However, little is known about how college drinkers engage in privacy management involving alcohol content. Through 48 interviews and a Communication Privacy Management lens, this study uncovered criteria on which students relied to develop relatively impermeable boundaries around alcohol posts, the ways they collectively negotiated privacy with peers, and how participants implicitly and explicitly communicatively negotiated privacy turbulence. Findings suggest important connections between the co-occurrence of online privacy management and identity management, including how facework is involved in remediating privacy breaches and the co-opting of privacy. Findings also inform efforts to educate college drinkers about on-and-offline strategies to manage alcohol-related SNS content.     

The Fallacy of Misplaced Concreteness: Its Importance for Critical and Creative Inquiry

In Science and the Modern World, Alfred North Whitehead (1925/1953) critically discusses the historical development of science and its larger impact on our civilization and culture today. The fallacy of misplaced concreteness (FMC) is a notion central to his analysis, both of the process of inquiry and to the general sustainability of quality of life. This paper is part of a panel of four presentations relevant to the theory, practice, and teaching of science. In this paper I identify the FMC as a set of variations on the central theme of misplacing concreteness, by mistaking the abstract for the concrete, and I define the component notions involved. More than half of the paper involves a representative range of concrete examples of the FMC. The realm of the aesthetic, of patient and sensitive attention, the full range of immediate bodily feeling, and the variety of real values revealed therein, turns out to be both the victim of and the remedy for the FMC. As Whitehead says: "Sensitiveness without impulse spells decadence, and impulse without sensitiveness spells brutality" (1925/1953, p. 200).     

The “Wicked Problem” of Neutral Description: Toward a Documentation Approach to Metadata Standards

Increasingly, metadata standards have been recognized as constructed rather than neutral. In this article, we argue for the importance of a documentation approach to metadata standards creation as a codification of this growing recognition. By making design decisions explicit, the documentation approach dispels presumptions of neutrality and, drawing on the “wicked problems” theoretical framework, acknowledges the constructed nature of standards as “clumsy solutions.”     

Family Reading Behavior and Early Literacy Skills in Preschool Children From Low-Income Backgrounds

This study investigated the family reading behavior of 233 preschool children from low-income backgrounds who were attending Head Start. Parents completed a survey of their family reading behavior, including Child Reading, Parent Reading Interest, and Parent-Child Reading Interaction, and provided demographic data on their educational level, parent and child age, and family size. Children's receptive vocabulary, story and print concepts, letter knowledge, and general emergent literacy skills were assessed in the fall of their preschool year. Analyses focused on the variation in family reading behavior, the relationship between different dimensions of family reading behavior, and the contribution of family reading behavior to early literacy skills. Results indicated that Parent-Child Reading Interaction and Child Reading Interest were significantly related to children's early literacy skills. In addition, multiple regression analyses indicated that Parent-Child Reading Interaction was a small yet significant predictor of children's receptive vocabulary, story and print concepts, and general emergent literacy skills, above and beyond the influence of demographic variables. Child Reading Interest was a significant, albeit small, predictor of letter knowledge above and beyond these demographic controls. Implications of these results for the early literacy education of children of low-income families are discussed.     

Curriculum continuity and school to university transition: science and technology programmes in Malawi

This paper reports on a study that explored issues of curriculum continuity at the school to university level transition in Malawi. It bases its analysis on the school integrated science curriculum and university science and technology programmes. Data were collected through interviews, documentation and classroom observations. The findings show that gaps do exist, with both the ‘intended’ and the ‘experienced’ curriculum, between integrated science and the requirements of university science and technology programmes in the three categories of the knowledge of science, science as a way of knowing and general knowledge and skills. With respect to the investigative nature of science, gaps exist only with the delivered curriculum. Implications for both the integrated science curriculum and the university science and technology programmes are discussed.
