In the current age of academic rigor, standards and accountability, the fostering of caring relationships in the classroom
may not always be a priority. Expressing care for another person is a skill that can be taught and nurtured through a supportive
educational environment. Sociodrama encourages each of its participants to develop self-confidence and self-expression through
risk-taking and exploration in activities that explore real life personal feelings and situations. By using sociodrama as
a means for exploring issues in the classroom it is possible to celebrate participants’ individuality and to create caring
and nurturing relationships among educators and students. This article examines the research describing the benefits of including
sociodrama in the elementary curriculum. 相似文献

This study reflects a naturalistic, interpretive 5-month study in a public school morning kindergarten regarding the children’s
social development and creation of a peer culture during the transitional months into public education. The main focus of
the research was the children’s perspectives on these transitions and their evolving classroom community and peer culture
in response to the teacher, classroom and school environment. This study captures the dynamic and complex flow of activity
that occurs in classrooms, the give and take of relationships, and the agency that children take in developing peer culture
as one piece of community. Elements of the peer culture that are foregrounded include secondary adjustments as realized in
clean-up strategies, protecting play materials over time, and hypothetical competition with the afternoon kindergarten class. 相似文献

Zusammenfassung Angesichts der staatlichen Klimaschutzziele stellt sich die Frage, wie diese mit m?glichst geringer Beeintr?chtigung einer
sicheren Versorgung zu günstigen Preisen erreichbar sind. Erdgas, das im Vergleich zu anderen fossilen Energietr?gern deutlich
kohlenstoff?rmer ist und darüber hinaus bei der Verbrennung auch keine weiteren Schadstoffe emittiert, kann hier einen Beitrag
leisten. Gegenw?rtig hat Erdgas für die Versorgung mit W?rme sowie bei der Erzeugung von Strom eine erhebliche Bedeutung,
die zukünftig weiter wachsen wird. Anhand verschiedener Szenarien werden Prognosen zur weiteren Entwicklung von Erdgas und
die Auswirkungen auf die CO2-Emissionen angestellt. Es zeigt sich, dass der Anteil von Erdgas im Bereich der W?rmeversorgung von 46 % auf 56 % steigen
wird. Durch ?nderung des Energiemix und Effizienzsteigerungen kann der CO2-Aussto? für Raumw?rme daher bis 2020 um 8,3 % gesenkt werden. Für die Stromerzeugung werden alternative Szenarien berechnet.
Beim derzeitigen Energiemix k?me es zu einer j?hrlichen Steigerung des CO2-Aussto?es um 0,8 %. Würde Kohle komplett durch Gas ersetzt, k?nnte der CO2-Aussto? j?hrlich um 1,9 % gesenkt werden.

Given the governmental climate targets, the question arises how these targets can be achieved without affecting a secure and cheap energy supply. As natural gas causes less carbon emissions than any other fossil fuel it might be able to make a contribution in this regard. Currently, in the generation of heat and power natural gas plays a significant role, which will further increase in the future. Using several scenarios, we predict the development of the importance of natural gas and the consequences for carbon emissions. The calculations show that the share of natural gas for the supply of heat will increase from 46 % to 56 %. Efficiency increases together with changes in the structure of power generation can reduce heating-related carbon emissions by 8.3 % until 2020. For power generation, we calculate alternative scenarios. If the current structure of power generation is held constant, carbon emissions will increase by 0.8 % p.a. If instead natural gas completely replaces coal and lignite, the carbon emissions will be reduced by 1.9 % per year.

In order to develop successful teaching approaches to transformations of matter, we need to know more about how young students
develop an understanding of these processes. In this longitudinal study, we followed 25 students from 7 to 13 years of age
in their reasoning about transformations of matter. The questions addressed included how the students’ understanding of transformations
of matter changed and how we can make sense of individual learning pathways. In interviews performed once or twice every year
the students described and explained three situations: fading leaves left on the ground, a burning candle, and a glass of
water covered with a glass plate on which some mist had formed. When analysing the interviews, we found a common pathway of
how the students’ ideas changed over the years in each one of the situations. When analysing individual student’s interviews
with Ausubel’s assimilation theory we could discern subordinate, superordinate and combinatorial learning. How these findings
can contribute to an improvement of teaching about transformations of matter is discussed. 相似文献

This study was designed to analyze the effects of the support programs provided in education welfare action zones. Education
welfare action zone policy came into effect by government from 2003 to guarantee actual educational opportunity to disadvantaged
children in urban areas by providing educational, cultural, and welfare service. Education welfare action zones were selected
in low-income group area in the metropolis. In this regard, both quantitative and qualitative analytical methods were used
to ascertain the effects of the program. The qualitative analysis included a preliminary examination of conditions prior to
the actual commencement of the program, which was then followed by an investigation of specific schools used, as case studies
in order to identify the changes that had taken place during the program’s implementation process, and the program’s effect.
Meanwhile, a quantitative analysis was employed to verify the actual changes that took place in several different aspects,
changes that were revealed by the case studies. 相似文献

This paper examines differences in mathematics achievement among eighth-grade students using a secondary analysis of the data.
The students, who are from Malaysia, had participated in the Trend International Mathematics and Science Study (TIMSS) 1999.
A series of school, home, demographic and socio-economic variables were used to investigate the differences in the mean student
mathematics scores. Evidence from the data shows that gender, the language spoken at home, expected educational level, family
background, and home educational resources and aids have a significant influence on the students’ level of mathematics achievement. 相似文献
