It is under debate whether the neural representation of numbers and letters might rely on distinct neural correlates, or on a mostly shared neural network. In the present study, a total of 47 children in fifth grade (Experiment 1) and sixth grade (Experiment 2) simply copied numbers and letters on a touch screen while brain activation changes were recorded by means of functional near‐infrared spectroscopy (fNIRS). fNIRS data of both experiments and a joint analysis revealed that a shared neural network, particularly in the left hemisphere, was activated in response to both number and letter copying. Interestingly, no difference was observed in brain activation patterns between these two stimuli, as revealed by Bayesian analysis. Our findings indicate that both number and letter copying lead to similar brain activation in children. We further suggest methodological and applied applications of these findings in the frame of educational neuroscience. 相似文献

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning. 相似文献

Our pre-university chemistry students face problems achieving sufficient quality in chemical inquiry. To try to enhance the quality of student performance in chemical inquiry, Dutch pre-university chemistry students (age 17) carried out an authentic research project on Diffusion of ions in distilled water. The learning materials for this student inquiry project, the teaching scenario and the website were designed in cooperation with five chemistry teachers. Three teachers from this network and two other teachers also implemented the project with 80 students to find out whether the emphasis on relevant concepts of evidence (CoE) improves the quality of student inquiry outcomes. This part – with its emphasis on the CoE – in the student inquiry task is based on four key features: the students feel motivated to explore, focus their attention on, give meaning to and reflect upon CoE. In teams students conducted a guide experiment, analysed a scientific article, did an inquiry and wrote a report, discussed CoE with peers on the Internet and rewrote their reports. All lessons were observed, field notes were made and analysed on whether the intended student activities had been realised. The Internet discussion was recorded in a database and analysed. The first and final reports of all teams were coded and analysed. Also the students appreciation of the activities was assessed. The teaching and learning activities were realized to a very large extent as planned in the design. The emphasis on CoE resulted in 65% of the students achieving a sufficient level of quality in their final reports. 相似文献

Developmental trajectories of externalizing behaviors in childhood and adolescence 总被引:11,自引:0,他引:11
This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and semiparametric mixture models. Overall, males showed higher levels of externalizing behavior than did females. Aggression, opposition, and property violations decreased on average, whereas status violations increased over time. Group-based trajectories followed the shape of the average curves at different levels and were similar for males and females. The trajectories found in this study provide a basis against which deviations from the expected developmental course can be identified and classified as deviant or nondeviant. 相似文献

A nine‐country survey of the life orientations, values and institutional trust of 8948 young people at the upper end of the secondary school age range was set up at the University of Würzburg in the year 2000. Key findings demonstrate that these young people value personal autonomy and are orientated to success in their professional lives and that they especially trust human rights and environmental groups. Religion is associated positively with humanitarianism and in some countries negatively with modernity. These findings provide an indication of the typical life stances of future opinion‐formers and illustrate methodological issues thrown up by international research. 相似文献

Children learning the basic multiplications, use knowledge which they acquired in former stages. Certain additions, for instance the doubles, known by heart, can support the learning process for multiplication. It makes a great difference in cognitive achievement whether children know multiplication facts by heart or whether they are able to figure out basic multiplications. If education supports the development of informal thinking strategies, children become so skilled at this, that the border between figuring out and knowing by heart will gradually disappear. By using informal strategies children will acquire a flexible mental structure of multiplication facts instead of a collection of rules. 相似文献

Higher education policy-making may attempt far-reaching reform of the post-secondary system and its inherited institutions. It may be oriented towards the replacement of distinctions between the academic and the non-academic as well as the transformation of the traditional university concept by means of a new conception of the organization of the post-secondary sector, the comprehensive university. Higher education policy-making may display not only great ambition but also policy extravagance. Maybe the Swedish 1977 higher education reform is the most ambitious attempt so far to implement the notions inherent in the comprehensive university. Maybe the element of policy extravagance was at times most conspicuous in the extended period of policy-making in Sweden culminating in the 1977 reform bill as it was even suggested that the universities of Uppsala (1477) and Lund (1668) were to be officially designated Högskolan i Uppsala and Högskolan i Lund-Malmö respectively. It may be interesting to find out the attitudes of those responsible for the day-to-day operations of the universities and colleges. This article presents the results of the first national survey of Swedish teachers and researchers in so far as they pertain to the evaluation of the 1977 reform. 相似文献
