Audience‐perceived anxiety patterns of public speakers

Gray's neurological theory of anxiety (1982, 1990; Gray & McNaughton, 2000) predicts that state anxiety will decrease with continuous exposure to a fear arousing stimulus. Previous studies of psychological and physiological state anxiety patterns during public speaking have reported a pattern of progressively decreasing anxiety levels consistent with this phenomenon, known as habituation. In the current report, the extent to which the state anxiety behaviors of speakers conform to the habituation pattern is examined. In the first of two studies, 30 novice speakers presented informative speeches to audiences of 18 to 20 fellow students. These speeches were videotaped and replayed in their entirety for observers (N=30) who rated the severity of each performer's speech anxiety behaviors. In the second study, each videotaped presentation was divided into one‐minute segments and presented in random order to a new set of observers (N=25). Procedures in the second study were designed to control for rater expectations that state anxiety would decline over time. Overall, behavioral measures of public speaking state anxiety displayed a continually declining pattern associated with habituation.     

ComPratica: A Virtual Community of Practice for Promoting Biology Teachers’ Professional Development in Brazil

Teachers’ professional development is a key factor in improving science education, but it shows limited impact when only a small number of teachers is reached, or when it focuses on only one aspect of teachers’ development, such as learning science content, and is disconnected from teachers’ practice. In order to increase the impact of our work on teachers’ professional development, we implemented in 2007 ComPratica, an online network intended to establish a virtual community of practice involving biology teachers and biological education researchers. We present here the results of the first 2 years of this project, obtained through an analysis of the number and distribution of actions performed by the participants in the community, the kinds of activities in which they are engaged, and the themes addressed in their messages. From these data, we conclude that ComPratica is effectively functioning as a community of practice and is leading to changes related to both teachers’ and researchers’ professional development, which seem capable of reducing the research–practice gap in science education.     

Curriculum as Experienced by Students: How Teacher Identity Shapes Science Notebook Use

This mixed-methods case study examined the notebook entries of one class of 22 second graders as a way of examining how teacher identity shaped the way students experienced their science curriculum. These notebook entries were created during lessons with three different teachers over the course of one school year, using similar kit-based materials to teach science. The entries were coded for inquiry phase, percent missing or incomplete entries, and driving force (teacher-driven, student-driven, or balanced); chi-squared analyses revealed significant differences among the notebook entries created by the same students during lessons taught by each of the three teachers. Qualitative observations of each teachers' instruction around notebook use supported these quantitative differences, and suggested that the differences in curriculum as experienced by students could be attributed to differences in teacher identity, both who the teacher is and what they do in the classroom. These findings indicate that students' notebooks are useful tools for examining how teachers' identities might shape how elementary students experience science curriculum, and that they can be used to help structure more effective professional development plans for each teacher.     

The Monster Within: How Male Serial Killers Discursively Manage Their Stigmatized Identities

Investigations of identity management regarding serial killers are sparse and rarely account for the communal discourse surrounding serial homicide. Such studies are essential to understanding the intersections of stigma and identity, particularly for the exploration of reframing that is severely limited for deviant populations. This interpretive study examined 13 interviews with serial killers to explore stigmatized identity management. The analysis revealed that male serial killers rejected their stigmatized identity by indicating a lack of control over their non-normal behavior or by justifying their actions. They also indicated that societal influences, such as previous traumatic experiences and communal discourse surrounding serial killing, influenced their identity management.     

Grade level, study time, and grade retention and their effects on motivation, self-regulated learning strategies, and mathematics achievement: a structural equation model

The present study complements previous research findings with new data to improve our understanding of the relationship between motivational variables and academic performance in math mediated by self-regulated learning (SRL). A structural equation model with predictor (i.e., grade retention, grade level, and study time), process (i.e., perceived usefulness of SRL strategies, self-efficacy for the use of SRL strategies, and reported use of SRL), and product variables (i.e., academic achievement in mathematics) is proposed. The model was analyzed in two samples of data (calibration and validation samples). The first sample served to fit and respecify the model, and the second one was used to analyze the consistency of the findings of the first sample. A sample of 756 middle school Portuguese students participated in the current study. The results indicate that SRL is positively and significantly related to academic achievement and that the latter is, in turn, powerfully determined by perceived usefulness and self-efficacy, although students’ reported use of SRL strategies decreases from 7th to 9th grades. Self-efficacy and perceived usefulness of SRL strategies were also found to decrease as grade retention increased. These results are discussed with regard to the relevance of self-efficacy and perceived usefulness of SRL strategies in increasing academic achievement.     

The future of HRD

What organizational, technological and training developments will become crucial in the coming years, and what consequences will they have for human resource development? These questions have led to a study carried out by the faculty of Educational Science and Technology at the University of Twente, in the Netherlands. The ultimate aim of the study was to create an inventory of trends and developments which professionals deem to be influential with regard to the future HRD field. One direct catalyst for the study was the report of a similar study in the United States, involving HRD executives, carried out by the American Society for Training & Development. Following a brief explanation of the research plan and methods, this article describes the findings of the Dutch study an compares these with the results of the American research. It concludes with comments regarding the implications of the information obtained through this investigation.     

Measuring Beliefs in Centimeters: Private Knowledge Biases Preschoolers' and Adults' Representation of Others' Beliefs

A novel task, using a continuous spatial layout, was created to investigate the degree to which (in centimeters) 3‐year‐old children's (N = 63), 5‐year‐old children's (N = 60), and adults' (N = 60) own privileged knowledge of the location of an object biased their representation of a protagonist's false belief about the object's location. At all ages, participants' knowledge of the object's actual location biased their search estimates, independent of the attentional or memory demands of the task. Children's degree of bias correlated with their performance on a classic change‐of‐location false belief task, controlling for age. This task is a novel tool for providing a quantitative measurement of the degree to which self‐knowledge can bias estimates of others' beliefs.
