Dynamical Patterns in the Development of Clapping

The development of a complex rhythmical behavior—clapping—is modeled using a formal, explicit model of coupled oscillator dynamics. Even though this behavior manifests a good deal of nonstationarity and high variability within and across subjects, results indicate that these properties may be dynamically modeled quantitatively as well as qualitatively. Results suggest that clapping goes through a less stable period of relative coordination between 3 and 7 years before more stable absolute coordination is achieved. Nevertheless, in that the clapping behavior is affected in highly predictable ways by inertial loading of the limbs, the same underlying dynamic seems responsible for the coordination of both the younger and older children. Developmentally, the behavior of the coordination variable (relative phase) changes from a nonconstant magnitude in younger clappers to a constant magnitude in older clappers. These results suggest that development of proficiency in rhythmic motor skills displays developmental changes that can be understood well in dynamical terms.     

The relationship between teachers’ emotional intelligence and classroom discipline management

One of the fundamental problems of educational systems in many countries is related to classroom discipline. This reflects one of the worst problems faced by teachers. Classroom discipline management strategies play an effective role in creating positive teacher‐student relationships. One of the factors that influence behavior management in a classroom is emotional intelligence. Therefore, this study analyzing how teachers emotional intelligence influences the management of discipline in a classroom and the relationship between gender, academic formation, and service time of teachers with their emotional intelligence. Its sample comprises 559 basic and secondary school teachers. An Emotional Competence Questionnaire, a Scale of Teacher Efficacy in Classroom Management, and a personal and professional data inquiry have been used as instruments. Results show that teachers who have more capacity to deal with emotion demonstrate a greater management of discipline in the classroom. Most of the relationships in the model are statistically significant.     

Toronto multiagency child abuse research project: The abused and the abuser

Information from 422 cases of child mistreatment in Toronto was gathered from the files of a child welfare agency and a children's hospital. These data were compared to patterns reported in previous studies and clinical writings on child mistreatment to investigate similarities and differences in families whose children have been abused in Canada, England, and the United States. Findings from the present study were similar to others in many respects. The differences were primarily in the area of lower incidences of such problems as perinatal difficulties in the children and intellectual limitations and social isolation in the parents; however, there was a higher incidence of single-parent families. The results suggest that clinicians should bear in mind that child mistreatment cannot be ruled out on the grounds that no serious problems have been noted for the child or the family.     

The social stratification of the German VET system

Germany is widely known for its vocational education and training (VET) system and its dual apprenticeship system in particular. What is often overlooked, however, is the vertical stratification within the German VET system. This is the focus of this study. Our analysis shows that the VET system, like the German school system, is highly stratified, resulting in large differences in labour market opportunities. We elaborate on three dimensions of vertical stratification: VET system vs. higher education, fully qualifying vs. prevocational VET programmes and segmentation of the fully qualifying VET programmes by educational attainment and career prospects. All three stratification dimensions are closely linked to school attainment and thereby to social origin.     

Students’ conscious unknowns about artefacts and natural objects

This study attempts to characterise what 7th- and 12th-grade students believe they do not know about artefacts and natural objects, as well as the dependence of what is unknown on a knowledge of these objects. The students were asked to make explicit through questioning what they did not know about a sample of objects. The unknowns generated were categorised according to a scheme based on lexical semantics theory. Two of the categories focused specifically on imprecise unknowns expressed through What is X? questions, and on unknowns concerning functions. The results showed, firstly, that a lower grade level and lower knowledge of a certain class of objects was associated with more imprecise unknowns. Secondly, unknowns about the functions of artefacts were significantly more frequent than unknowns about the functions of natural objects at any of the grade levels. Overall, the results were consistent with the hypothesis of a correspondence between knowledge and unknowns.     

The ADHD spectrum and everyday life: experience sampling of adolescent moods, activities, smoking, and drinking

Using an experience sampling methodology, the everyday lives of 153 adolescents with low, middle, or high levels of attention-deficit/hyperactivity disorder (ADHD) characteristics as assessed by either parent or teen were examined. Twice each hour, across two 4-day recording intervals, participants in a longitudinal study of stress and health risks logged their behaviors, moods, and social contexts. Those with high, in contrast to low, ADHD symptom levels recorded more negative and fewer positive moods, lower alertness, more entertaining activities relative to achievement-oriented pursuits, more time with friends and less time with family, and more tobacco and alcohol use. Fewer associations emerged with parent-defined than with teen-defined subgroups, although the differences in alertness, peer and family contexts, entertainment versus achievement activities, and substance use were consistent across sources. Even at subclinical levels, ADHD characteristics were associated with behavioral patterns and contexts that may promote peer deviancy training, unhealthy lifestyle behaviors, and vulnerability to nicotine dependence.     

Teachers' social class,professional dispositions and pedagogic practice

Through theoretically driven case studies, the research reported here considers the ways in which students in different social class settings are inducted into school knowledge. The paper brings to the centre the social class positioning of teachers in considering their role in schooling processes. The central question of the paper is whether we can establish a relationship between teachers' own social class backgrounds, their professional dispositions and their pedagogic practice. The interest emerges from a long-standing assumption that teachers are middle class, and reproduce the practices associated with that social location. The paper is exploratory and is not able to provide a definitive answer to the question of the relationship between class, professional disposition and pedagogic practice. Although it suggests a relationship between teachers' social class position and schooling practices, the main contribution of the paper is to offer a metric for exploring the issue further. That is, through a specifically selected sample, the paper provides a means for considering the implications of teachers social class background, professional dispositions and pedagogic practice for the processes of the reproduction of social inequality, and its interruption.     

Effortful Control, Surgency, and reading skills in middle childhood

We examined the associations between components of temperament and children’s word and pseudo-word reading skills, in a school-age sample using a within-family internal-replication design. We estimated the statistical prediction of word and pseudo-word reading in separate regression equations that included the main effects of, and two-way interaction between, Surgency and Effortful Control. Children with better Effortful Control scores showed better reading skills. Surgency was unrelated to reading skills, but moderated the effect of Effortful Control. The positive association between reading skills and Effortful Control was present only for children who were low in Surgency. Thus, reading achievement in school-age children is optimized by strong Effortful Control, but these processes may be disrupted for those children who are high in Surgency.     

Teacher-perceived temperament and educational competence as predictors of school grades

Associations between teacher-perceived temperament, educational competence (EC), and school grades in mother language (ML) and mathematics (Math) were assessed in 3212 students (1619 girls) in Secondary School (aged 13–19) taken from a nationally representative Finnish sample. Temperament was assessed with scales from the TABC-R and DOTS-R batteries. EC consists of cognitive ability, motivation, and maturity. Activity, persistence, distractibility, inhibition, and negative emotionality were significantly associated with both ML and Math grades. EC turned out to mediate the relationship between temperament and school performance and moderated the relationship of activity to Math. The findings show a high association between teacher-rated temperament and school performance and indicate a strong “halo effect” between temperament, EC, and school grades.
