Self‐selection of Simple Computer Activities by Infant School Pupils

Abstract Many activities from the infant class curriculum may be enhanced by realising them in the interactive context of a computer environment. This raises the question of whether young children can make choices among such activities that would reflect an awareness of their difficulty and a motivation to master them. In this research, infant class pupils were provided with software that offered unconstrained opportunities to select a range of related activities and the level of difficulty at which they would be tackled. Choices and response times were automatically recorded over a period of three weeks. These choices remained stable throughout that time and were biased towards the easiest options. There was some improvement in performance although little evidence of choice strategies that could be effective in driving such improvement. There was no evidence of sex differences in frequency of using the computer.     

K–12 Blended Teaching Readiness: Model and Instrument Development

Abstract

An increasing number of K–12 schools have adopted blended learning approaches. Current empirical research has been sparse regarding preparing teachers for blended teaching, including the skills they must develop to teach in blended contexts. This research is focused on that weakness, with the purposes of systematically identifying the skills needed for teaching in a blended learning context and of developing and testing an instrument that can be used to determine individual and school-wide readiness for blended teaching. In this study we present a measurement model used to develop items for measuring K–12 blended learning readiness. Specifically the instrument contained the following top-level areas: (a) foundational knowledge, skills, and dispositions, (b) instructional planning, (c) instructional methods and strategies, (d) assessment and evaluation, and (e) management. Each top-level construct also had two to four subconstructs. Through confirmatory factor analysis using survey responses from 2,290?K–12 teachers we found that the data met all four fit statistics cutoffs set forth in the literature (root mean square error of approximation [RMSEA]= 0.041, comparative fit index [CFI]?=?0.926, Tucker–Lewis index [TLI]?=?0.923, standardized root mean square residual [SRMR]?=?0.041, X2?=?978.934, df?=?1992).     

Child Development and Neuroscience

Although developmental psychology and developmental neuroscience share interests in common problems (e.g., the nature of thought, emotion, consciousness), there has been little cross-fertilization between these disciplines. To facilitate such communication, we discuss 2 major advances in the developmental brain sciences that have potentially profound implications for under standing behavioral development. The first concerns neuroimaging, and the second concerns the molecular and cellular events that give rise to the developing brain and the myriad ways in which the brain is modified by both positive and negative life experiences. Recurring themes are that (1) critical, new knowledge of behavioral development can be achieved by considering the neurobiological mechanisms that guide and influence child development, and (2) these neurobiological mechanisms are in turn influenced by behavior.     

Connectionism and learning to read: Steps towards a psychologically plausible model

We consider the prospects and need for a psychologically plausible connectionist model of the development of word recognition skills. We present an outline of the Seidenberg and McClelland (1989) distributed, developmental model of word recognition and naming. We emphasize certain incompatibilities between this model and the assumptions underlying it and psychological evidence from studies of children learning to read. In particular, we emphasize the importance of phonological skills as precursors and facilitators of learning to read. We argue that it may be possible to develop a connectionist model of the development of word recognition skills which, by having a built in knowledge of phonology, will be more consistent with evidence from studies of both normal and dyslexic children.     

An Empirical Investigation of Impact Moderation in Test Construction

This investigation constructed four different kinds of test sections using three methods of test assembly that incorporate the goals of simultaneous moderation of three kinds of impact-gender impact, African-American impact, and Hispanic- American impact. The test sections were administered undetectably to random samples from the appropriate population. The results were evaluated by comparison of the characteristics of moderated sections with those of parallel operational sections. Almost all methods of test assembly produced either moderation of impact in the appropriate direction or no change in impact. Taking impact into account in test assembly tended to lower reliability slightly, raise concurrent validity slightly, and maintain the construct measured by the parallel operational section. It also reduced the relative efficiency for test takers in the middle score range while increasing efficiency for those with more extreme scores.
