刍议"以德治国"

江泽民同志提出的“以德治国”思想是指把道德作为管理国家、调控社会的手段,来指导国家各项方针、政策的创制、实施和执行。它的提出,是对历史上“德治”思想的总结与提升,并有其丰富的理论和现实基础;民主的道德性理论、政治社会化理论、治国方略理论和德法辩证关系等。当然,在实施“以德治国”的过程中,我们还必须处理好以下几个方面的问题;坚持邓小平理论的指导、营造舆论文化环境、加强道德教育和加强党的领导等。     

幕末、明治时代日本侵华思想检证

幕末、明治时代,日本已经开始侵略中国,各种各样的侵华思想不断问世,成为其侵略行动的战略指导和精神支柱。这时的侵华思想以大陆政策为核心和主线,以“神国”理念和民族优越论为特征,是封建扩张主义、殖民主义和民族狂妄主义的混合物,对后来日本大规模的侵华思想理论的泛滥和行动的推进产生了深远的影响。

Consensus among stakeholders about success factors and indicators for quality of online and blended learning in adult education: a Delphi study

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met.     

Assessment,Grade Level and Learning

Researchers have identified assessment as a very crucial influence on the learning strategies adopted by students. The present study carried out on Secondary 2, Secondary 4, and Junior College 2/Pre-University 3 students shows that the Singapore students did not favour the Surface Approach in their learning of English and Mathematics. The nature of the discipline and the cognitive demands of the examinations carried considerable importance for students in their choice of learning strategies. Despite the heavy emphasis on excelling in examinations, students did not rely solely on surface and achieving strategies to attain their goals.
