Addresses the implementation and evaluation of a constructivist course and extends the argument toward the induction of teachers into critical constructivism through their own action-research projects. Data is taken from a single case study illustrating the changes in the professional life and reflective practice of one teacher in Brazil. (AIM)

The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…

Evaluated the PREG conceptual model of human question asking. Found the model was sufficient as it accounted for nearly all of the questions produced by students, and was discriminating in that it could identify the conditions in which particular classes of questions are or are not generated.

Personal responsibility has long been considered an important component in self-directed learning. And yet, a theoretical understanding of personal responsibility that could lead to meaningful instrumentation has eluded the field. The present study considers the merits of the Triangle Model of Responsibility (TMR) (Schlenker, Britt, Pennington,…

The purpose of this study was to investigate the effects of a Computer-Assisted Instruction Material (CAIM) related to "photosynthesis" topic on student cognitive development, misconceptions and attitudes. The study conducted in 2002-2003 academic year and was carried out in two different classes taught by the same teacher, in which…

In this article, we draw from research on cognitive development, sociocultural learning, and organizational development to examine the key factors in teachers' professional learning. Our review of this literature suggests that looking at teachers' prior knowledge, the nature of their interactions, the representations they produce and use, and the…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

Audio-based virtual environments have been increasingly used to foster cognitive and learning skills. A number of studies have also highlighted that the use of technology can help learners to develop effective skills such as motivation and self-esteem. This study presents the design and usability of 3D interactive environments for children with…

An instrument to measure teachers' instructional practices, the Instructional Practice Questionnaire, was developed and validated in three phases. The questionnaires focused on three domains of instructional practices: cognitive, interpersonal, and interpersonal. First, an initial questionnaire was developed for a pilot study, and data were…

Over the course of development, the ability to switch between different tasks on the basis of feedback cues increases profoundly, but the role of performance monitoring remains unclear. Heart rate indexes can provide critical information about how individuals monitor feedback cues indicating that performance should be adjusted. In this study,…

The study examined scaffolding interactions between deaf children and hearing mothers in which story reading was used as a tool to aid in the development of narrative comprehension and linguistic reasoning. The dyadic interactions were examined from the perspective of the theoretical works of Vygotsky (1934/1962, 1978, 1929/1981, 1960/1981). The…

This study estimated separately the unique effects of three dimensions of good practice and the global effects of a composite measure of good practices on the cognitive development, orientations to learning, and educational aspirations of students during their first year of college. Analyses of longitudinal data from a representative sample of…

There is considerable interest in the potential non-musical cognitive and academic benefits of music listening and instruction to children. This report describes three lines of research relevant to this issue, namely, the effects of: (1) focused music listening on subsequent task performance (the Mozart effect); (2) music instruction; and (3)…

This study investigates the role of basic elements of a learning context namely: the given tasks, the nature of the provided tools, and the pupils' gender in their choice of tools provided by an open problem-solving computer environment. Pupils' choice of tools is discussed through the description of an experiment involving the interaction of (30)…

Theory of mind (ToM) was examined in late-signing deaf children in two studies by using standard tests and measures of spontaneous talk about inner states of perception, affect and cognition during storytelling. In Study 1, there were 21 deaf children aged 6 to 11 years and 13 typical-hearing children matched with the deaf by chronological age. In…
