There is an increasing emphasis on the importance of social competence for children's development, well-being, and learning. Thus age- and context-appropriate measures are needed. This study addresses the structural validity of the Lamer Social Competence in Preschool (LSCIP) scale, developed to accommodate the Nordic model of early childhood pedagogy. The authors specify the theoretical basis for a bi-factor model of social competence. This model is tested in a large (n?=?1157), community based sample of Norwegian children, including teacher- (at age 2, 3, and 4), mother- (at age 4), and father- (at age 3) reports. A model with a main factor for social competence, and three bi-factors fit data across ages and reporters, with factorial, but not strong, invariance over time.  相似文献

During a 15‐year longitudinal study, 31 Finnish students (risk group) who had been identified as having deficiencies in reading and writing readiness at pre‐school through the German Breuer–Weuffen Differentiation Test were compared with their peers (n = 62) in order to study long‐term differences that emerged at the starting point of the study. In 1999, the students in the risk group were found to achieve significantly lower final school grades and they also had lower perceptions of their own scholastic competence. In 2005, students in the risk group perceived themselves as less competent than their peers in social acceptance, sense of global self‐worth areas and in the strength‐perceptions related to mathematical thinking, learning skills, and self‐regulation. Path analyses showed that verbo‐sensory motor status measured at pre‐school age had long‐term effects on participants’ educational life‐course and global self‐worth. Possible explanations of the findings and implications for early identification are discussed.  相似文献

Abstract

Pulmonary diffusing capacity (Dlco), together with spirometric variables, arterial oxygen tension (paO2) and cardiac output were determined before and at intervals after maximal arm cranking, treadmill running and erogmeter rowing. Independent of the type of exercise, Dlco increased immediately post‐exercise from a median 13.6 (range 7.3–16.3) to 15.1 (9.3–19.6) mmol min‐1 kPa‐1 (P <0.01). However, it decreased to 11.6 (6.9–15.5) mmol min‐1 kPa‐1 (P <0.01) after 24 h with cardiac output and paO2 at resting values, and Dlco normalized after 20 h. Thoracic electrical impedance at 2.5 and 100 kHz increased slightly post‐exercise, indicating a decrease in thoracic fluid balance, and there were no echocardiographic signs of left ventricular failure at the time of the decrease in Dlco. Also, active muscle (limb) circumference and volume, and an increase in haematocrit from 43.8 (38.0–47.0) to 47.1 (42.7–49.8) (P <0.01), had normalized at the time of the decrease in Dlco. Vital capacity, forced vital capacity, forced expiratory volume in 1 s, peak and peak mid‐expiratory flows did not change. However, total lung capacity increased from 6.8 (5.0–7.6) to 7.0 (5.1–7.8) litres (P <0.05) immediately after exercise and remained elevated at 6.9 (5.1–8.7) litres (P <0.05) when a decrease in Dlco was noted. The results demonstrate that independent of the type of maximal exercise, an approximate 15% reduction in Dlco takes place 2–3 h post‐exercise, which normalizes during the following day of recovery.  相似文献

The study investigates whether sport is an especially risky environment for sexual harassment to occur. It explores female students’ experiences of sexual harassment in organized sport and compares them with their experiences in formal education, by addressing the following research questions: (1) Are there any differences in female sport students’ experiences of sexual harassment in sport and education? (2) Are there any differences in female sport students’ experiences of sexual harassment from coaches and teachers? (3) Are there any differences in female sport students’ experiences from peer students and peer athletes? A total of 616 female students from three different European countries, Czech Republic, Greece and Norway, answered a questionnaire. The results revealed that the students had experienced more sexual harassment in an educational setting than in a sport setting. Further analysis showed that this was primarily due to sexual harassment from peers in school. In Greece and Norway, there was no difference between occurrences from teachers and coaches, yet in Czech Republic coaches appear to harass more than teachers. The difference between sexual harassment occurring from peers in sport and in education is discussed in relation to whether the sense of belonging/camaraderie that a sport club member may experience might function as a barrier for sexual harassment to occur—because it embarrasses or hurts a teammate. In addition, sport clubs and teams are governed by their respective sport rules and possibly by additional club/team rules, which may also establish extra inside-club/team boundaries for acceptable and nonacceptable/harassing behaviors. This article concludes that greater emphasis ought to be placed on education; not only toward shaping safer teacher/coach behaviors, but also toward the student/athlete behaviors.  相似文献

Phagocytosis and exocytosis are two cellular processes involving membrane dynamics. While it is easy to understand the purpose of these processes, it can be extremely difficult for students to comprehend the actual mechanisms. As membrane dynamics play a significant role in many cellular processes ranging from cell signaling to cell division to organelle renewal and maintenance, we felt that we needed to do a better job of teaching these types of processes. Thus, we developed a classroom-based protocol to simultaneously study phagocytosis and exocytosis in Tetrahymena pyriformis. In this paper, we present our results demonstrating that our undergraduate classroom experiment delivers results comparable with those acquired in a professional research laboratory. In addition, students performing the experiment do learn the mechanisms of phagocytosis and exocytosis. Finally, we demonstrate a mathematical exercise to help the students apply their data to the cell. Ultimately, this assay sets the stage for future inquiry-based experiments, in which the students develop their own experimental questions and delve deeper into the mechanisms of phagocytosis and exocytosis.  相似文献

Individuals in five European countries—Finland, France, Germany, Spain, and the United Kingdom (n = 1184)—completed a survey exploring the relationship between organizational dissent and workplace freedom of speech. Results revealed workplace freedom of speech is positively correlated with dissent among the entire sample in France and in Germany. Results in Spain were nonsignificant. In the United Kingdom, there was a negative relationship between workplace freedom of speech and dissent. There was a negative relationship between workplace freedom of speech and articulated dissent and a positive relationship with latent dissent in Finland. Moreover, MANCOVA testing showed nationality to have a significant effect on organizational dissent and workplace freedom of speech. Germans scored the highest on dissent and workplace freedom with Spain scoring the lowest.  相似文献

With the advent of e-journal preservation projects and publisher digitization of journal backfiles, academic libraries have begun to move their corresponding print volumes of these titles to storage to avoid duplication and save space. This article examines the supporting justifications, outreach mechanisms, and logistical procedures undertaken at American University Library to relocate the entire bound journal collection to offsite storage in order to address severe physical space constraints and to support patron use of and preference for electronic journal content. In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project.  相似文献

Abstract

In 2014, the Finnish National Board of Education launched a new core curriculum with the aim of meeting the skills and competence requirements of the 21st century. The purpose of this case study was to find out what transversal competencies Finnish eighth graders developed and how they experienced studying in a problem-based transdisciplinary course, which was arranged for the transitional stage between the former and the new curriculum. The qualitative data consisted of questionnaires and interviews. The analysis followed the methods of qualitative content analysis. When asked about their learning, the students commented on not having learnt much, referring to the discipline-based knowledge. Instead, they had learnt skills through teamwork, problem solving, and expression of their views and opinions, an aspect that they did not clearly connect with the things to be learnt at school. Many students felt that they acquired the competencies that they would need later in their lives. The students’ teamwork had a crucial impact on their learning experience. The timeframe for the integrative approach needs careful consideration; the learning process in this course was perceived as being successful because it was long enough. Our study highlights that focusing on students’ views is critical when reforming curriculum.  相似文献

We prospectively examined the role of physical activity involvement, weight status, and motor functioning capability in 1st grade for social status among other pupils in class in the 4th grade. Our sample included 80 Norwegian 1st grade pupils (Girls N = 44; Boys N = 36). 1st grade motor proficiency and objectively measured physical activity, but not weight status was predictive of 4th grade social standing among pupils in class as measured by socio‐metric status. Interaction findings also revealed that 1st grade healthy weight children being proficient in the motor domain benefit more in terms of their social standing among peers in 4th grade than do 1st grade overweight but equally motor proficient children. Being physically active in the 1st grade seems more important for social standing among peers in 4th grade for 1st grade girls than for boys. Results may inform early intervention efforts in school to enhance pupils' psychosocial development.  相似文献
