This study investigates whether lesson structure (LS) matters and which components are important for academic engagement during the first grade of secondary education. Data from videoed lessons of 10 Dutch and 12 Indonesian teachers analyzed using an observation protocol show that six LS components are found, that between class and over measurement variability in LS is evident, and that on average LS change is not a linear function of time. Class differences over time do exist and several personal and contextual characteristics affect LS. Links between LS (student work time, reviewing and introducing new content) and academic engagement are evident. 相似文献

Do non-science, technology, engineering, and mathematics (STEM) students’ views about STEM studies correspond with how STEM students actually perceive these studies? This paper deals with this issue by comparing higher education students’ attitudes towards STEM studies between those who actually did a STEM study and those who did not. The attitudes of the first category of students have been referred to as perceptions and the attitudes of the second category as preconceptions. The study included 1,935 students in higher education. The results confirm both small and large differences between the preconceptions and perceptions, and show significant differences between suitably qualified students (i.e. eligible for STEM studies) and other students. At the end of this paper, we will discuss the implications of this study for future research and offer some suggestions for practice. 相似文献

This paper deals with the relation between children's home literacy environments (HLE) and their literacy development in the first phase of primary school. On the basis of a broad conceptualisation of the HLE, we identified three home literacy profiles (rich, child‐directed and poor HLE). Firstly, we related these profiles to socio‐cultural factors (more specifically, ethnicity and socio‐economic status [SES]). We found an association between the HLE and ethnicity/SES, indicating that (Dutch) majority children and children from high SES families had, in general, the most stimulating HLEs. On the other hand, we observed considerable variability in HLEs within ethnic minority and low SES groups. Subsequently, we related the HLE profiles to literacy outcomes in kindergarten, first and second grade. We found that, after controlling for relevant background characteristics, the HLE had an effect on children's vocabulary scores in first grade, and their general reading comprehension both in first and second grade. 相似文献

Abstract Longitudinal research provides valuable information about change and progress towards elite performance. Unfortunately, there is a lack of longitudinal research in handball. In this study, 94 youth handball players (oldest group: n = 41; age 15–17 and youngest group: n = 53; age 13–15) were followed over a three-year period. Repeated Measures ANCOVA was conducted to reveal longitudinal changes in anthropometry and physical performance between elite and non-elite players, controlling for maturation. Maturation effects were found for anthropometry (P < 0.01) and some physical performance measures in strength and speed (P < 0.05). The lack of significant interaction effects revealed that during the three years of the study the elite players did not improve their physical performance more rapidly than the non-elites. Furthermore, they had a similar anthropometric profile to the non-elites. Elite players performed better on the Yo-Yo Intermittent Recovery test (P < 0.01; on average 24.0 in the youngest group and 25.2% in the oldest group over the three years) and on the speed and coordination items (P < 0.05; shuttle run: 3.6 and 5.1%; cross hopping: 11.0 and 14.8%, handball-specific shuttle run: 7.6 and 7.7%; slalom dribble test: 10.7 and 8.9%; sprint 30 m: 4.9 and 3.9%). Additionally, Yo-Yo performance and coordination with and without a ball were the most discriminating factors between the playing levels. In conclusion, youth coaches and scouts within team handball should recognise the importance of good skills and an excellent endurance for talent identification purposes. 相似文献

To investigate the effect of innovations in the teaching–learning environment, researchers often compare study results from different cohorts across years. However, variance in scores can be attributed to both random fluctuation and systematic changes due to the innovation, complicating cohort comparisons. In the present study, we illustrate how using information about the variation in course grades over time can help researchers and practitioners better compare the grades and pass rates of different cohorts of students. To this end, all 375,093 grades from all 40,087 first‐year students at a Dutch university during a period of six consecutive years were examined. Overall, about 17% of the variation in grades could be attributed to random variation between years and courses. With respect to passing courses, this percentage was almost 40%. Nonsignificant improvements in grades could be flagged as highly significant when this is ignored, thus leading to an overrepresentation of significant effects in educational literature. As a consequence, too many educational innovations are claimed to be effective. 相似文献

The Developmental Model of Sports Participation proposes two pathways towards expertise in sports between 6 and 12 years of age: early specialization and early diversification. This study investigated the effect of sampling various sports and of spending many or few hours in sports on fitness and gross motor coordination. Altogether, 735 boys in three age groups (6-8, 8-10, and 10-12 years) were profiled using a fitness test battery. A computerized physical activity questionnaire was used to obtain data on sports participation. In the eldest group, (M)ANCOVA showed a positive effect of sampling various sports on strength, speed, endurance, and gross motor coordination (P < 0.05). A positive effect of many hours per week spent in sports was apparent in every age group. These data suggest an acute positive effect of many hours in sports and a latent positive effect of early sampling on fitness and gross motor coordination. Multiple comparisons revealed that boys aged 10-12 years, who spent many hours in various sports, performed better on standing broad jump (P < 0.05) and gross motor coordination (P < 0.05) than boys specializing in a single sport. Therefore, our results highlight the importance of spending many hours in sports and sampling various sports in the development of fitness and gross motor coordination. 相似文献

This study was designed to investigate the distribution of interpersonal profiles based on students' and teachers' perceptions and to examine the associations between students' perceptions of teacher interpersonal behaviour and learning motivation in Indonesia. Participants were 1900 secondary school students (grades 7 to 9) across 66 (Mathematics and EFL) classes from 11 public schools in Indonesia. The results show that a variety of interpersonal profiles could be distinguished, that teachers perceive themselves more favourably than their students do, and that students' perceptions of teacher interpersonal behaviour and their learning motivation are associated. Influence and Proximity were found to be important determinants of student motivation; both dimensions are related to a more autonomous motivation, while Influence is also associated with a more controlled motivation. Contrary to the existing knowledge base, this study reveals that the relationship between teacher interpersonal behaviour and student motivation is more strongly connected to Influence than to Proximity. 相似文献

This study investigated the role of maturity timing in selection procedures and in the specialisation of playing positions in youth male basketball. Forty-three talented Dutch players (14.66 ± 1.09 years) participated in this study. Maturity timing (age at peak height velocity), anthropometric, physiological, and technical characteristics were measured. Maturity timing and height of the basketball players were compared with a matched Dutch population. One-sample t-tests showed that basketball players were taller and experienced their peak height velocity at an earlier age compared to their peers, which indicates the relation between maturity timing and selection procedures. Multivariate analysis of variance (MANOVA) showed that guards experienced their peak height velocity at a later age compared to forwards and centres (P < .01). In addition, positional differences were found for height, sitting height, leg length, body mass, lean body mass, sprint, lower body explosive strength, and dribble (P < .05). Multivariate analysis of covariance (MANCOVA) (age and age at peak height velocity as covariate) showed only a significant difference regarding the technical characteristic dribbling (P < .05). Coaches and trainers should be aware of the inter-individual differences between boys related to their maturity timing. Since technical characteristics appeared to be least influenced by maturity timing, it is recommended to focus more on technical characteristics rather than anthropometric and physiological characteristics. 相似文献
