Teaching prereading skills with a talking computer

The phonological awareness skills of nonreaders were trained using an oddity task (e.g., which word in the series sit, fit, cat has the odd sound in its middle position). As training progressed, the basis of the oddity decision was shifted from rhyming, to consonant onsets, to consonant and vowel phonemes. The words were spoken by a DECtalk speech synthesizer. One of the experimental groups was given printed as well as computer generated speech feedback while the other was given just computer speech feedback. The alternative training control group based their oddity decisions on meaning rather than sound and was also given just computer speech feedback. Only children with low letter-sound knowledge showed pre-test to post-test gains in performance on a rhyming task compared to the control group, and these gains were not influenced by print feedback. In contrast, only children with high letter-sound knowledge, who were given print feedback during learning, showed pre-test to post-test gains in performance on a phoneme deletion task compared to the control group. These results indicate that a combination of high letter-sound knowledge and print feedback facilitates awareness of phonemes among children who cannot yet read or spell, but awareness of rimes is not facilitated by either high letter-sound knowledge or print feedback. Although consistent with bi-directional, causal models of phonological awareness and literacy, these results indicate that the definition of literacy employed by such models may require expansion. This new definition should include proto-literacy — knowledge of letter-sound and other print-sound relationships that are learned before becoming literate and that may influence the acquisition of awareness of some sub-syllabic units of speech.Abbreviations WPPSI Wechsler preschool and primary scale of intelligence - WRAT-R Wide range achievement test, revised     

Advancements in instructional design theory: Contextual module analysis and integrated instructional strategies

In the past decade, research and theoretical advancements in both cognitive science and instructional technology have led to updates in instructional design theory. In this article, we review two areas in which the updates make important contributions: information analysis for higher-order cognition, and instructional strategies to improve acquisition of such higher-order processes. From our reviews of the literature, we propose procedures for conducting a contextual module analysis and designing integrated instructional strategies. An additional purpose of the article is to demonstrate the need for researchers in educational technology to lead in the discovery of theories contributing to acquisition of higher-order cognition.     

What characterizes a productive research department?

The correlates of average departmental annual research journal publication rates of faculty were examined in three disciplines: chemistry, history, and psychology. Variables studied included factual information about each department, faculty perceptions and ratings, and graduate students' perceptions and ratings. Content included academic programs, specific policies and practices, characteristics of students, faculty, facilities, etc., as well as the quality of teaching and human relations in the departments. Although the common results indicated the importance of able faculty and students, a strong emphasis on research and the provision of time and funds for faculty to pursue research, there were discipline-specific patterns of results. In chemistry the pattern of productive departments suggested large research laboratories, in history a scholarly apprenticeship approach, and in psychology an emphasis on research over practice. Discipline specific studies may be the best approach to understanding research productivity.     

Principles for the design of dynamic tracing environments for novice programmers

This paper describes the principled design of a computational environment which depicts an animated story of the execution of programs for novice programmers. The design principles are aimed at solving the problems that novice programmers face when learning new programming languages, and are embodied in an Animated Program Tracer (APT) for Prolog. The goal of this research is to develop a more systematic, if not yet scientific, basis for the design of animated tracing tools.     

Neurobehavioral factors associated with referral for learning problems in a community sample: evidence for an adaptational model for learning disorders

We evaluated community general education (CGE; n = 178), community special education (CSE; n = 30) and hospital-referred (HR, n = 145) children (ages 7-6 to 11-11) prospectively over a 2-year period. During this period, 17 CGE children were referred for evaluation (community referred; CR). Prior to referral, CR children performed more poorly than community-nonreferred (CNR) children on cognitive ability, academic achievement, attention problems, and information processing. CR group performance was equivalent to that of CSE and HR groups, but HR children showed poorer academic achievement. Referred children performed more poorly on all measures than nonreferred, whether they met formal diagnostic criteria for a learning disorder or not. Learning disorders may be better conceptualized as a context-dependent problem of functional adaptation than as a disability analogous to physical disabilities, raising questions about the validity of using psychometric test scores as the criterion for identification.     

Does the presentation style of questions inserted into text influence understanding and retention of science concepts?

The purpose of this research was to determine the relative effects of the presentation style of questions inserted into text materials for students in university introductory biology. The sample was randomly assigned to seven treatment groups of approximately equal size and read a 2,354-word passage on bacterial adaptations taken from a popular university general biology textbook. Experimental treatment groups read the same passage with (1) questions placed at the beginning of selected paragraphs and with the questions presented with (2) underlining, (3) in uppercase, (4) set above the paragraph, (5) underlined and set above, and (6) set above in uppercase respectively. The criterion variable was a 20-item multiple-choice exam with five possible answers per question given once to all students immediately after they read the passage and again exactly four weeks later. Presentation strategy groups were contrasted against the reading without questions groups. Four of the six groups reading with questions at the beginning of the paragraph scored significantly higher on the test given immediately after the reading than the group reading without questions. There were no significant differences between any of the group scores for the test given four weeks after reading. Other differences in results between these strategies and implications for text writers are discussed.     

Parental coping with children's negative emotions: relations with children's emotional and social responding

This study examined the relation between parents' reactions to children's negative emotions and social competence. Additionally, the role of parental emotional distress in children's emotional socialization was examined. The emotional reactions of 57 preschoolers (33 girls, 24 boys; M age = 59.2 months) were observed during their free-play interactions. Parents (mostly mothers) completed questionnaires about their reactions to children's negative emotions. An index of children's social competence was obtained from teachers. Results indicated that the relation between harsh parental coping strategies and children's emotional responding was moderated by parental distress. In addition, the relation of the interaction of parental coping and distress to children's social competence was mediated by children's level of emotional intensity. It was concluded that distressed parents who use harsh coping strategies in response to children's negative emotions have children who express emotion in relatively intense ways. In turn, these children find it relatively difficult to behave in a socially competent manner.
