Causal Connections Between Mathematical Language and Mathematical Knowledge: A Dialogic Reading Intervention

The acquisition of early mathematical knowledge is critical for successful long-term academic development. Mathematical language is one of the strongest predictors of children's early mathematical success. Findings from previous studies have provided correlational evidence supporting the importance of mathematical language to the development of children's mathematics skills, but there is limited causal evidence supporting this link. To address this research gap, 47 Head Start children were randomly assigned to a mathematical language intervention group or a business-as-usual group. Over the course of eight weeks, interventionists implemented a dialogic reading intervention focused on quantitative and spatial mathematical language. At posttest, students in the intervention group significantly outperformed the students in the comparison group not only on a mathematical language assessment, but on a mathematical knowledge assessment as well. These findings indicate that increasing children's exposure to mathematical language can positively affect their general mathematics skills. This study is an important first step in providing causal evidence of the importance of early mathematical language for children's general mathematical knowledge and the potential for mathematical language interventions to increase children's overall mathematics abilities.     

Using computer-delivered natural speech to assist in the teaching of reading

The findings of a pilot study designed to evaluate a computer system developed to assist in the teaching of reading to beginners are presented. The system uses digitised speech and the content is based upon a reading scheme already in use in the schools. Twenty children, ten in the intervention group and ten in the control group, in two schools were involved over a four-week period. Subjects were tested on a standardised reading test, a list of the 30 most frequently occurring words in written English, and on words from the published scheme. The experimental group improved their scores significantly more than the control group only on the standardised reading test. The results suggest the system can be helpful and that its effect goes beyond the words being practised.     

Supporting Communication of Girls with Rett Syndrome and their Mothers in Storybook Reading

In this study mother-child storybook reading was explored as a context within which to support early symbolic communication of girls with Rett syndrome. Baseline measures of mother-daughter interaction were gathered as mothers read familiar and unfamiliar storybooks with their daughters. Then three experimental interventions were studied in the homes of four girls: (a) resting hand splints, (b) light tech augmentative communication systems such as voice-output devices and symbols, and (c) very basic parent training. Access to devices, symbols, and training increased the frequency of each of the four girls, labeling and symbolic communication during storybook reading. Parent training was particularly useful in increasing the percentage of appropriate switch use by three of the four girls. The study suggests that parents can provide substantial support to early communication development in girls with Rett syndrome, if they are provided with basic information and materials.     

Dynamic Assessment of Young Children: Educational and Intervention Perspectives

Dynamic/interactive assessment (DA) has been motivated by the inadequacy of conventional static tests to provide accurate information about the individual's learning ability, specific deficient functions, change processes, and mediational strategies that are responsible for cognitive modifiability. A growing need for DA with young children has emerged recently because decisions about treatment should be made as early as possible. The objectives of this paper are to review the major criticism of the standardized static testing approach, present the theoretical basis of the DA approach, describe current research on DA of young children within educational and intervention perspectives, and suggest some directions for future research. The theoretical foundations of the presented research derive from Vygotsky's sociocultural theory, specifically the zone of proximal development concept, and Feuerstein's mediated learning experience theory. DA has been applied with different clinical and educational groups and was found to be more accurate in reflecting children's learning potential than static tests, especially with minority and learning disabled children. The mediational strategy is also reported as more effective than other intervention approaches (e.g., graduated prompt). The DA approach was found useful in assessing outcome effects of cognitive education programs aimed at enhancing learning how to learn skills. Crucial issues of cost-effectiveness, training, reliability and validity, and generalization are discussed.     

Perceptions and experiences of annual report preparers

Between 1986 and 1993, tertiary education institutions, [TEIs] in New Zealand have transformed their annual reports from being uninformative, untimely and unobtainable documents, to ones that are well-presented, comprehensive and readily available in a timely fashion (Coy, Tower & Dixon, 1994). This paper reports a study of the events and experiences according to report preparers in bringing about this change, including the incentives and difficulties that they have been facing.The study uses data collected from 48 staff involved in report preparation at 15 of the 37 TEIs that are in New Zealand. These data are qualitative, and are analysed from a realist perspective mixing causal analysis and interpretive understanding (Silverman 1985).The study suggests that the mandated changes to reporting are seen as one facet of several recent public sector reforms in New Zealand. Interviewees felt that the changes to reporting were driven externally by legislation, and internally by the stances taken by some chief executive officers and by the professional ardour of some accountants. Moreover, the Audit Office was seen as a prominent agent of change.The general reactions of preparers of reports to the reforms range from strong support to resentment and scepticism. A major concern voiced was the potential for data reported by TEIs to be used for political purposes. On the other hand, improved staff motivation was noted in many institutions as well as greater cost consciousness and awareness of student, needs. However, these positive attributes were probably derived from the reforms in general, and not just from the changes to reporting.     

Defending the Boundaries: Identifying and Countering Threats in a Usenet Newsgroup

This article is an account of a Usenet newsgroup whose participants, in response to a perceived 'invasion' of 'barbarians,' explored and articulated the value of the group, the nature of the crisis facing it, and the strategies available to meet the crisis. The newsgroup facilitated political and personal support for some gay, lesbian, or bisexual men and women. The primary threat to the group was the increasing number of newcomers who were oblivious to established norms, who tended to view access to the group as a commodity, and who attempted to impose 'outside' paradigms on the operations of the group. Defensive strategies involved calling on rhetorical devices (such as flaming or ostracism) or structural resources (such as employers, network operators, or lawsuits). All strategies had the potential to backfire, but rhetorical strategies were less risky, more available, and more community affirming than strategies requiring access to structural resources. Through this account, the article addresses the mutual linkages and dependencies between the social and technical organization of computer-mediated communication (CMC) networks, the community-building activities taking place through those networks, and the social, legal, and economic structures in which those networks are embedded.
