Academic workload: the silent barrier to the implementation of technology-enhanced learning strategies in higher education

The effect of technology-enhanced learning (TEL) strategies in higher education has arguably been transformative despite the not-insignificant barriers existing in this context. Throughout the discourse very little attention has been paid to those primarily responsible for this implementation—academic teaching staff. This paper aims to highlight the impact of academic workload allocations, an often silent barrier to the uptake of TEL strategies in higher education. We will discuss the effects of academic identity and culture, preferential time allocation to associative activities, academic technological capacity, university policies and workload and funding models on the uptake, and implementation on TEL in higher education. Our aim is to highlight the risks to staff, students and institutions should these concerns not be addressed and to propose a model for utilisation by all staff responsible for implementing flexible workload models supportive of further implementation of TEL strategies across the sector.

Talking Together,Learning Together: The Story of English PGCE Student Teachers’ Adventures in Classics

This article reports on the first two phases of a project to promote the classics through English at Key Stage 3, a scion of the Cambridge Schools Classics Project. We discuss the primary importance of speaking and listening in the English classroom both for the individual and the collective, and reflect on the power and importance of using classic tales in English as a means of promoting good-quality oracy. We comment on the precarious position of both oracy and story in the 2014 national curriculum. We report on the impact of a project during which student teachers were introduced to classical oral storytelling and encouraged to use it in their teaching. Findings suggest that the student teachers recognised oracy and storytelling as fundamental to their developing pedagogy and that they saw the need to promote oracy.     

Critical thinking as room for subjectification in Education for Sustainable Development

Issues of sustainability are complex and often steeped with ethical and political questions without predefined or general answers. This paper deals with how secondary and upper secondary teachers discuss these complex issues, by analysing their aims for Education for Sustainable Development. With inspiration from discourse theory, their articulations about students as political subjects are analysed. Critical thinking emerged as a nodal point in teachers’ discussions. In this study, critical thinking is articulated as having various qualitative meanings related to different epistemological views. On one hand, critical thinking is articulated to invite room for subjectification; but on the other hand, room for subjectification is challenged when critical thinking is articulated through the educational aims of qualification and socialisation. A consequence of changing epistemological view might be that political and ethical issues take a back seat.     

一种基于关系视频盲水印算法

针对视频水印的特征,提出一种利用视频帧采样点均值曲线相交性确定嵌入帧的方法：在水印信息嵌入时,利用嵌入帧三个亮度最大分块位置关系和DC值大小实现每帧2bit信息的嵌入。实验证明,该算法对常规攻击具有良好的鲁棒性。     

党政革新运动中的总清查运动

党政革新运动是国民党在抗战结束后,为解决政治、经济、军事等方面的问题,实现建国大业而进行的一场自救运动。总清查运动,作为党政革新运动在党务方面一项具体的实践活动,自1946年10月1日在全国范围内开展至1947年8月结束,其取得的效果差强人意。清除腐败分子,吸收新鲜血液,重整革命阵容,完成建国使命的目的没有实现;工作懈怠,党员腐化,组织涣散等党内问题,也没有因为总清查运动而有所改善。国民党这部庞大的官僚机器,在面临党内腐败,党外共产党的挑战时,失去了自我改造、自我更新的能力。     

几种碱改性ACF电极材料对电容性吸附处理RO浓水氨氮及其动力学研究

实验选用Na OH、KOH及氨水为电容性吸附电极材料活性碳纤维ACF的改性剂,通过比较原材料与几种改性材料去除盐分和氨氮效果,研究其电容性吸附氨氮动力学过程,实验结果表明:改性ACF相比未改性活性碳纤维电容性吸附污染物质发生变化,其中氨氮改性后ACF在盐分和氨氮去除上都表现出优越性,ACF-NH3除盐平均去除率达到9.69%,高于ACF-unmodified5.29%,氨氮平均去除率达到41.80%,高于改性前的27.33%;Na OH和KOH改性ACF在氨氮去除上均低于改性前,但其平均除盐率分别为6.53%、6.64%高于改性前;准一级、二级和Elovich经典动力学模拟其氨氮吸附动力学表明准一级和二级动力学具有更高的R2但其qe值误差较大,相比Elovich则能反应出其吸附趋势;另外,通过高斯多项式模拟结果和趋势均较经典动力学符合其吸附过程,R2均大于0.9557,一定程度上可以借鉴使用。

简析有效课堂教学

富有成效的英语堂教学是高校英语教育的关键。课堂教学中需要充分发挥教师与学生的主观能动性,使教师能够采用多种教学管理手段吸引学生的注意力,激发学生的学习积极性,从而使学生能够主动参与到课堂教学活动中,进而提高语言应用能力与自身素养。教师与学生的协作互动有利于课堂教学的开展。教师在课堂教学活动中应当及时辨识与合理把控学生的身心状态,使学生能够在教师的引导下积极有效开展课堂英语学习。
