This study investigated the cognitive, attitudinal and behavioural aspects of the career maturity of 1380 secondary school and junior college students.

The findings reveal a general weakness in career exploration and in the students' development of career decision-making skills. While no significant gender differences can be observed, there is strong evidence to indicate that career development does mature with age. The findings also suggest a positive association between career maturity and academic performance and between career maturity and parental involvement. Among the resource persons identified, teachers are the least consulted. They are also rated as the least helpful source of career information.

In the light of these findings, implications for the planning and implementation of career guidance in schools to enhance the career maturity of the students are discussed and suggestions made.  相似文献

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).  相似文献

Es gibt einige Hinweise darauf, dass Vorstellungen vom Lehren und Lernen sowohl für das Handeln der Lehrkr?fte im Unterricht als auch für Zielkriterien auf der Ebene der Schüler eine Rolle spielen. Dabei gelten konstruktivistisch orientierte Sichtweisen als besonders günstig. Empirische Untersuchungen dazu gibt es jedoch bislang nur auf einzelne fachdidaktische Inhaltsbereiche bezogen. In der vorliegenden Studie werden konstruktivistisch orientierte Lehrereinstellungen mit Merkmalen des Unterrichts (?ffnung des Unterrichts im Hinblick auf Entscheidungsm?glichkeiten für Schüler/-innen und Strukturierung des Unterrichts) sowie mit Einsch?tzungen der Schüler/-innen (Selbstbestimmungsempfinden und Interessantheit des Unterrichts) in Beziehung gesetzt. Die Ergebnisse best?tigen die Theorie: In den Klassen der Lehrer/-innen mit überwiegend konstruktivistischen Vorstellungen von Lernen und Lehren gibt es mehr Freir?ume, ohne dass der Unterricht weniger strukturiert abl?uft. Zudem empfinden sich die Schüler/-innen als selbstbestimmter und sch?tzen den Unterricht als interes-santer ein.  相似文献

ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, Mage?=?13.2 y, SDage?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献

In a joint project involving European association staff and sports scientists, basic structural data were collected on British, Swedish, Spanish and German athletics clubs to be used for analysis of hypotheses concerning conditions of participation in sports clubs, particularly by children and adolescents. The results showed clear differences in organizational level as well as membership and activity structures in comparisons between European countries and within Germany. The findings revealed the differential functions and significance of sports clubs in the context of the respective institutions and cultures.  相似文献

The comments in this article are designed to survey productive fields of a contemporary directed history of sport in a heuristic way. These comments represent a resolute plea for an in-depth interdisciplinary access to sport whereby in particular a hermeneutic perspective is seen as being productive. The main question on the meaning which reaches out beyond the performative completion of a sport activity contains an interdisciplinary cultural scientific programme, which must pay equal attention to the historical prerequisites of the narrative form and the medial constitution of such a generation of importance. Historians have also recently turned their attention to the cultural powers of sport. Classical questions on the functionalisation of sport by politics still attract the attention of contemporary history.  相似文献

On 1 August 1929 the Prussian Minister of Education enacted a regulation establishing“exercise and physical education” as an academic field of study to be offered at all universities and institutes of technology under his jurisdiction. This action served to successfully complete the process that had been evolving since the middle of the nineteenth century to recognize the discipline as a university level specialty in the face of considerable longstanding opposition. The gravest forms of opposition emanated from the universities themselves and starting in the middle of the 1920s were ultimately overcome by proceedings and argumentation. These circumstances are described in this contribution based on accessing and evaluating new sources. The central focus is on a memorandum written in February 1929 by the Göttingen University physical education lecturer Bernhard Zimmermann. The article concludes by classifying and assessing the act of 1929 with a view to the further development of the academic education of sports instructors in the ensuing era of National Socialism and the postwar period in West Germany and the Federal Republic of Germany.  相似文献
