Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system. 相似文献

Zusammenfassung.
Die Beweisentwicklungsumgebung -Mkrpsoll
Mathematiker bei einer ihrer
Hauptt?tigkeiten, n?mlich dem Beweisen mathematischer Theoreme
unterstützen. Diese Unterstützung mu? so komfortabel sein,
da? die
rechnergestützte Suche nach formalen Beweisen leichter und insbesondere
weniger aufwendig ist, als ohne das System. Dazu mu? die verwendete
Objektsprache ausdrucksstark sein, man mu? die M?glichkeit haben, abstrakt
über Beweispl?ne zu reden, die gefundenen Beweise müssen in einer am
Menschen orientierte Form pr?sentiert werden und vor allem mu? eine
effiziente Unterstützung beim Füllen von Beweislücken zur Verfügung
stehen. Das im folgenden vorgestellte $\Omega$-Mkrp-System ist
der Versuch einer
Synthese der Ans?tze des vollautomatischen, des interaktiven und des
planbasierten Beweisens. Dieser Artikel soll eine übersicht über unsere
Arbeit an diesem System geben.

This study addressed recruiting principals into low performing schools. A sample (N = 619) of principals, assistant principals, central office administrators, school counselors, and teacher-leaders from the
29th largest school district in the United States role-played as applicants for principal vacancies at schools classified
as low-performing based on results of standardized student achievement tests. The study had an experimental design and involved
use of a recruitment simulation. Rating jobs depicted on simulated principal recruitment announcements, principals and assistant
principals rated the job highest while school counselors rated the jobs lowest. Among the teacher-leaders, teacher-administrative
interns rated the job higher than did highly skilled educators or resource teachers. Implications for recruitment practice
and future evaluation research are discussed. 相似文献

In recent years significant international focus has highlighted the critical importance of managing life, learning and work in a constantly changing labour market. This changing world and the corresponding need for individuals to engage in repeated decision-making about learning and work has raised the importance of and necessity for the provision of career development services across the lifespan. This challenge is being addressed by many countries across the globe. Within this context, this paper discusses the initiatives enhancing the status of career service provision in Australia. 相似文献

This paper examines Brazil’s Sector Funds, an emerging research and development policy that seeks to increase public-private research collaboration. The first section sets the context of the ‘policy problem’. The second section discusses the policy’s implementation, and discusses its likely implications for Brazil and beyond. 相似文献

During the Cold War, Franco’s dictatorship attempted to use technological transfer and nuclear technology to strengthen the geopolitical influence of his Government in Spain. This paper studies this process, with particular reference to the role played by German scientists as advisers to the Spanish nuclear project. 相似文献

Two basic approaches have been used by the literature focusing on the return to holding artistic works: the hedonic price model and the repeat-sales model. This paper provides a procedure for jointly estimating the two models in a way that take advantages of the unique information contained in each. A semiannual price index for Picasso prints is estimated by using a model derived from the basic framework of the hybrid models. The empirical results suggest that the hybrid model provides the most precisely estimated price index by reducing the level of price volatility.JEL Classification: C5, Z1p 相似文献
