Neonatal Stepping in Relation to Terrestrial Optic Flow

This experiment examined whether newborn stepping, a primitive form of bipedal locomotion, could be modulated by optical flow. Forty-eight 3-day-old infants were exposed to optical flows that were projected onto a horizontal surface above which the infants were suspended. Significantly more air steps were elicited by exposure to a terrestrial optical flow specifying forward translation than by a rotating optical flow or a static optical pattern. Thus, a rudimentary coupling between optical flow and stepping is present at birth, suggesting a precocious capacity in the newborn to perceive and utilize visual information specifying self-motion. The findings may help the early diagnosis of infants with visual or visual-motor deficits and the development of visually based interventions for disabled infants.     

Response sequence learning as a function of primary versus conditioned reinforcement

Two groups of pigeons were required to generate a fixed sequence of responses on three keys, for example, middle-left-right. One group received a small food reward (S^Food) following each correct response except the terminal one, which was followed by a large food reward. The second group received conditioned reinforcement from an overhead light (S^Light) for each correct response, with the terminal correct response followed by both S^Light and the large food reward. We manipulated length of sequence (3 or 7 responses) and duration of required interresponse interval (IRI; 1 to 9 sec). S^Light contingencies generated more accurate performances than did S^Food when sequence length was 3 responses but not when it was 7 responses. IRI duration influenced accuracy under the S^Light contingencies but not under S^Food. These results show that conditioned reinforcers sometimes generate more accurate sequence learning than do primary reinforcers, and that schedule contigencies influence which type of feedback will optimize performance. The results parallel those from the matching-to-sample and conditional discrimination literature.     

Communities,networks and ICT professional development across schools in close physical proximity

ABSTRACT

Many studies have focused on professional development within schools, while this article focuses on ICT (information and communications technology) professional development across schools. The aim of this article is to explore how the encouragement of communities and networks might contribute to ICT professional development across schools in close physical proximity. The study is based on a two-year action research project and interviews with the participants of a lead teacher community across five schools. Although the lead teachers and school leaders played a central role, ICT professional development was dependent on a complex interplay of different types of communities and networks, both within, across and outside the schools. This study illustrates how ICT professional development occurred in both expected and unexpected ways and emphasises the need for professional development to take account of the complex needs of teachers, rather than being a ‘one size fits all’.     

Engaging Students in Science Across the Primary Secondary Interface: Listening to the Students’ Voice

Most studies indicate primary students’ attitudes towards and interest in science decline as they progress into the secondary years. Longitudinal qualitative research exploring this phenomenon is rare as is research which focuses on the students’ voice as they cross the interface. In this study multiple qualitative data sources, supported by a ‘science interest’ composite scale, followed 20 students over 2 years. In contrast to baseline data on their peers these students, in general, maintained their interest in science. Apart from identifying the teacher’s pedagogical approach and classroom environment as two key issues in understanding these students’ journeys, the importance of listening to and heeding the students’ voice may be an even more critical concern in addressing the decline in students’ attitudes and interest in science.     

Free‐choice worksheets increase students' exposure to curriculum during museum visits

The museum visit is an important part of elementary school science teaching. However, a divide exists between teachers, who require curricular accountability, and museums, who emphasize free‐choice exploration. Can a carefully constructed worksheet bridge this divide by providing free‐choice exploration of curricular topics during the museum visit? In the present study, a theoretical framework was constructed to inform the design of worksheets as free‐choice learning devices. This framework was used to analyze the design of an existing museum worksheet. Subsequently, curriculum‐related conversations among school groups visiting a museum were monitored in groups supplied with the worksheet and in control groups without. Overall, the worksheet complied well with design criteria synthesized from the free‐choice learning literature. Furthermore, the use of the worksheet increased the number and diversity of curriculum‐related conversations among school groups during the visit. This study documents that the use of carefully designed worksheets may increase students' exposure to curriculum during a museum visit, and thus may help build better bridges between teacher needs and museum free‐choice identities. © 2007 Wiley Periodicals, Inc.

Prenatal Predictors of Postnatal Quality of Caregiving Behavior in Mothers and Fathers

SYNOPSIS

Objective. The quality of parental caregiving has been shown to affect children’s development from birth onward. Therefore, it is important to detect parents at risk for low-quality caregiving as early as possible – preferably before birth. Design. Observations of expectant mothers’ and fathers’ behavior when exposed to infant crying were examined as predictors of the quality of caregiving toward their own infant 6 weeks postpartum. Eighty-eight expectant mothers and 57 of their male partners were tested during the third trimester of pregnancy. Parents were filmed individually while caring for a crying Simulator Infant for 15 min; the quality of their caregiving was rated on sensitivity and cooperation. Also, cognitive interference on a working memory task and the ability to regulate physical force when exposed to infant crying were assessed. When their baby was 6 weeks old, parents were filmed and rated for sensitivity and cooperation during a 15-min interaction with their own infant at home. Results. Prenatal quality of caregiving behavior toward a simulator infant predicted postnatal quality of caregiving toward the own infant in both mothers and fathers. Cognitive interference and the ability to regulate physical force did not predict postnatal quality of caregiving behavior. Conclusions. Expectant parents’ quality of caregiving behavior toward a crying simulator infant predicted both mothers’ and fathers’ postnatal quality of caregiving behavior. Future research is needed to determine whether the simulator infant may be a useful screening instrument and training tool for parenting skills in at risk groups of parents-to-be.     

Social Justice in Swedish Post-16 Education? New Preparatory Programmes

Under a recent national curriculum reform in Sweden within a highly decentralised, competitive, and marketised education system, access to post-16 education is restricted. In this study, we map and analyse the early onset of new preparatory programmes. We draw on interviews with local politicians and school staff in six different municipalities, along with documents and statistics. The study is positioned within a framework of analysis of policy ideas and theoretical perspectives on inclusive education, equal education opportunities, and marketisation. Bernstein’s theoretical concept of “pedagogic rights” serves as a lens for the interpretation of the findings. The study suggests that the preparatory programmes tend to have marginalising effects for vast numbers of 16 plus students, in contrast to wider policy aims of social and economic inclusion and employability.
