师生交流的传播学分析

师生交流是一个贯穿教育全过程的重要概念,对它的研究不能仅仅停留在师生之间教学内容的传达上。该文以传播学的理论来分析师生交流的形式、手段、主要内容及不同定位产生不同的效果等,意在使师生交流在更宽的领域得到更深入的研究。     

"情感"在声乐演唱艺术中的体现与研究

声乐演唱中的情感处理表现在音色的变化、歌曲动态的变化,以及歌曲速度和力度的变化。而歌曲演唱的情感还体现注重歌曲词意内涵的理解和歌曲所表达的风格和韵味上。

论教师的职业法律素质

教师职业法律素质是一种后天获得的素质，具有社会性，习得性特征，由教育法规知识，教育法律意识和教育法规的实践操作能力所构成。教师应具有法律知识包括公民基本法律常识，职业法律知识和青少年儿童法律知识三个部分，教师具有一定的法律素质教育是正确行使职业权力的基础。

是褒扬“十六大”还是包装“生产力价值论”——再与胡义成先生商榷

我党提出要深入研究和探讨马克思的价值理论,是强调谱写新的理论篇章,是强调要用发展着的马克思主义指导当前的改革开放;十六大报告强调尊重劳动、知识、人才和创造,旨在调动一切积极因素,绝不是对劳动创造价值这一根本观点的否定;社会财富的源泉不等于就是价值的源泉,在价值源泉问题上劳动具有排他性,但在价值形成和价值分配问题上则不然;马克思《资本论》的学术价值以及它对全世界工人阶级解放事业的伟大作用,不容贬低和诋毁;地球上所有的财富和一切商品的价值,从古至今只能靠劳动来创造,非劳动主体创造使用价值和非一般人类劳动成为价值源泉的说教,纯属天方夜谭。     

Co-benefit of hazardous trace elements capture in dust removal devices of ultra-low emission coal-fired power plants

The co-benefit of hazardous trace elements such as mercury (Hg), arsenic (As), and selenium (Se) capture in dust removal devices of ultra-low emission coal-fired power plants was investigated. Feed fuel and ash samples collected from 15 different coal-fired power units equipped with ultra-low emission systems were characterized to determine the concentrations and distribution characteristics of trace elements. It was found that the low-low temperature electrostatic precipitator (LLT-ESP) and the electrostatic fabric filter (EFF) had greater abatement capacity for Hg than normal cold-side ESP (CS-ESP). Only 0.8%–36.1% of Hg escaped from LLT-ESP and EFF, whereas 42.1%–90.6% of Hg escaped from CS-ESP. With the employment of EFF and ESP (inlet temperature<125 °C), 72.3%–99.1% of As and 70.7%–100% of Se could be captured before the wet flue gas desulfurization (WFGD) system. The significance level of the effects on the abatement capacity for Hg, As, and Se in ESP were analyzed by the Pearson correlation analysis and grey relational analysis. The results indicated that the low inlet temperature of LLT-ESP had significant promotional effect on the simultaneous removal of Hg, As, and Se. The smaller particle size of fly ash can be conducive to the adsorption of hazardous trace elements. The inhibitory effect of sulfur content in coal was significant for the enrichment of Hg and Se in fly ash.

Chinese award-winning tutors’ perceptions and practices of classroom-based assessment

This study examines Chinese tertiary award-winning tutors’ perceptions and reported practices of classroom-based assessment. Seventeen tutors in the final stage of a national university teaching contest were individually interviewed. An interview framework was developed using three process dimensions of assessment for learning (AfL). A sequential and iterative analysis of resulting data was conducted based on Miles and Huberman’s protocols for qualitative analysis. Participants demonstrated a complex set of connections between perceptions and practices around issues of sharing standards, delivering feedback and response to external assessments. Results deviate from widely promoted principles of AfL and classroom-based assessment espoused in the international literature; in doing so, they challenge existing research and assumptions about the standardised and international nature of award-winning instructors’ assessment practices. Findings are discussed in relationship to understanding best practices in tertiary assessment, given emerging tertiary education markets. Practical implications for the further development of learning and assessment practices and theoretical implications for the AfL theory are also discussed.
