Prospective primary teachers’ perceptions about the use of mathematics homework     

Sven Trenholm  Mohan Chinnappan 《Teacher Development》2019,23(1):50-63

The benefit of homework (HW) has been the subject of ongoing debate among various stakeholders. Within this debate, and in relation to teacher development, prospective teachers’ views of HW have received limited attention. In this study, we survey primary pre-service teachers’ (‘PSTs’) views of HW use (n = 45 teaching grades 2–5; n = 39 teaching grades 6 and 7) in a single discipline (mathematics) at one large Australian university.

The literature suggests students in upper primary and secondary grades will benefit from the use of mathematics HW. Results of the study, in contrast, suggest our PSTs teaching early primary grades planned to give proportionally (but not significantly) more mathematics HW than those teaching later grades. Reasons for this disparity are discussed. We argue there is a need in teacher development to equip PSTs with a better understanding of how classroom and home-based learning work together in the development of mathematical understanding.  相似文献

Continuous usage of e-participation: The role of the sense of virtual community     

Mijail Naranjo-Zolotov  Tiago Oliveira  Sven Casteleyn  Zahir Irani 《Government Information Quarterly》2019,36(3):536-545

Local governments around the world are increasingly implementing e-participation platforms to involve citizens in consultation and decision-making processes. E-participation platforms usually succeed and produce positive effects in the community when adopted in the long-term scenario. The adoption of those platforms is still a challenge for local governments. The understanding of the factors that influence the continuous intention to use e-participation over time is critical for the design of diffusion and promotion strategies that motivate the citizens to keep using e-participation. This article explores the drivers that predict the post-adoption of e-participation platforms from the perspective of the sense of virtual community theory, that is the degree of affective attachment to a given community mediated by information technology. Specifically, our research model evaluates the association between the sense of virtual community with use behaviour and the continuous intention to use e-participation. Structural equation modelling was used to evaluate the data collected from 370 citizens who experienced an e-participation platform hosted by a European capital city. We found out that the direct association between the sense of virtual community and use was significant. Even though the direct association between the sense of virtual community and the continuous intention was non-significant, the indirect association sense of virtual community to use to continuous intention was statistically significant. This finding may indicate that the use behaviour is triggered by the influence of other members of the community for a short period of time, but it does not persist to influence the continuous intention over time.  相似文献

‘My success as a teacher amazes me each and every day’ – perspectives of teachers with learning disabilities     

Sven Nilsen 《International Journal of Inclusive Education》2013,17(5):479-497

The purpose of the article is to study the development of educational policy in Norway in the field of the unitary school system and to analyse whether the development can be seen as a move towards increasing inclusion. The educational policy, when seen over a long time span, has progressively aimed towards the development of a common compulsory school that has embraced increasingly more groups, across social and geographical divides. At the same time, the development has been characterised by discord and tensions, e.g. between standardisation and differentiation, coordination and special arrangements and organisational and pedagogical differentiation. Gradually, it was stressed that as many pupils as possible should be allowed to live and grow up at home and that special education was to be coordinated with the ordinary school as much as possible. Later on, inclusive education has been clearly formulated as a principle of education. It did assume a broadening of responsibility for the ordinary schools in order to develop an educational programme that can accommodate the diverse learning needs of all pupils. It is pointed out that the policy of the unitary school has to deal with a lot of critical dilemmas for moving further towards inclusion.  相似文献   

CO₂-Einsparpotenziale des Energietr?gers Erdgas     

Michael Br?uninger  Sebastian Schr?er  Sven Schulze und Henning V?pel 《Zeitschrift für Erziehungswissenschaft》2008,32(1):37-45

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.
