#1: labor begins on its own

In this position paper-one of six care practice papers published by Lamaze International and reprinted here with permission-the benefit of allowing labor to begin on its own is discussed and presented as an evidence-based practice that helps promote, protect, and support normal birth. The paper is written for childbearing women and their families. The accompanying commentary-written by a leading home-birth midwife and prominent national and international speaker on maternity care-describes further evidence of the disadvantages of inducing labor. The indications for and risks of induction are also explored. Lamaze International recommends that, unless there is a medical indication for induction, labor should be allowed to begin on its own.     

The Development of Implicit Memory From Infancy to Childhood: On Average Performance Levels and Interindividual Differences

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues.     

Open feedback in gymnastic judging causes conformity bias based on informational influencing

Abstract

The aims of this study were twofold: (1) to determine whether open feedback (i.e. the ability to hear or see the scores of colleague judges after each performance) would lead judges in gymnastics to conform with their colleagues, and (2) to identify the underlying process on which this conformity is based. Twenty-three certified Flemish judges in women's gymnastics were randomly divided into panels of a maximum of five judges. These panels had to rate the same 30 videotaped individual vaults: 15 in phase 1 and 15 in phase 2. Two independent variables were orthogonally manipulated: feedback (or no feedback) during phase 1 and feedback (or no feedback) during phase 2. The results of phase 1 revealed that the variation between the judges' scores was less within panels that had received feedback than within panels that had not received feedback. We therefore conclude that the availability of feedback elicits conformity among gymnastic judges. The results of phase 2 indicated that this conformity continued even when feedback was no longer provided, suggesting that the observed conformity was based on informational influencing (i.e. because of uncertainty about the correct responses) and not on normative influencing (i.e. out of fear of standing out in the group).     

The impact of concept mapping and visualization on the learning of secondary school chemistry students

The aim of this study was to examine whether the construction of integrated knowledge structures by students can be stimulated by concept mapping and by better visualization of concepts and their interrelationships. The investigation was carried out in regular teaching settings: chemistry courses in secondary schools in Flanders, in the domain of electrochemistry. A significant positive effect of extra attention to visualization on the learning achievement of students was found. However, significant effects of concept mapping as an instruction method could not be detected under the given research conditions.     

Developing the NAEP Content-Area Frameworks and Innovative Assessment Methods in the 1992 Assessments of Mathematics, Reading, and Writing

This article provides an overview of the consensus processes for the development of the frameworks underlying the NAEP assessments, with emphasis on those for the 1990 and 1992 assessments of mathematics, the 1992 assessment of reading, and the 1994 assessment of science. In addition, innovative assessment techniques included in the 1992 assessments of mathematics, reading, and writing are described, including use of mathematics tools, oral interviews, and portfolio assessment.
