高校教师职称评审工作现存问题及对策研究

高校职称评审工作关系到能否充分激发广大教师工作的积极性及创新性,关系到我国高等教育事业的持续、稳定、健康发展。现行的高校教师职称工作中出现了比如高校管理机制中职称评审分工不明确、评审标准异化、评审材料弄虚作假、评审过程失范等问题。在此基础上提出相应的对策,这对新时期完善高校教师职称评审工作、提高教师水平和教学质量具有重要的理论和实践意义。     

多维教育在大学和职高中的应用对比研究

随着中国与世界其他国家的交流越来越频繁,英语作为一种重要的交流工具,彰显的作用越来越明显。在语言知识的教学过程中,英语教学取得了举世瞩目的成就。但是,也有很多多维。在传统的英语教学过程中,以考试为中心的教学模式的弊端主要体现在学生英语水平的实际应用和学生自身能力的提高上。因此,在英语教学过程中,如何改变教学观念,深入探索课堂教学,以提高英语教学效率,从而全面发展学生的自主性、主体性和英语能力已经成为当代英语教学改革过程中的一个主要多维。这项研究的目的是为职高英语课程构建一个多维互动式教学模型。通过改变教学方法,我们努力提高学生的英语学习能力,培养学生对语言技能的综合利用,并促进深度学习。     

Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing

Complex oxides with tunable structures have many fascinating properties, though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach. Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic (1-x)BiTi_(1-y)/2Fe_yMg_(1-y)/2O₃–(x)CaTiO₃ (BTFM–CTO) solid solution in large area, confirming its ferroelectricity at the atomic scale with strong spontaneous polarization. Careful compositional tuning leads to a bulk magnetization of 0.07 ± 0.035 μ_B/Fe at room temperature, enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0 × 10⁻⁷ s/m. This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film, making it possible to explore a much wider space of composition, phase, and structure that can be easily scaled up for industrial applications.     

Research ethics: a safeguard for advanced technologies

With the fast development of cutting-edge technologies and their greater integration into human life, more ethical challenges emerge. The problem became more salient when the world''s first genetically edited babies were born in China in violation of existing ethical rules. Although the responsible researcher He Jiankui was sentenced for imprisonment for three years last December, it is still necessary to examine the current status of research ethics and the challenges in China. Has China set up a sophisticated research ethics system? For research ethics and their implementation in China, are there unique national characteristics? Can the dominant ethics principles primarily developed from life science research be equally adopted in the emerging artificial intelligence research and development? At an online forum organized by National Science Review (NSR) and through subsequent correspondences among forum participants, NSR Executive Editor-in-Chief Mu-ming Poo and guest moderator Hepeng Jia asked three scientists and three bioethicists or philosophers of science and technology in the field to examine the dynamic development of research ethics in China.

顺应与重塑:我国校园体操发展的生态适应与主动转型

新中国成立以来我国校园体操发展的价值理念、存在样态与治理实践发生了重大变革与结构转型。价值理念从工具理性的健康诉求上升到了价值理性的生命育化,践行了从强体卫国到重技荣国,身心之育到生命之育的目标转向与效用升级,内蕴有对学校体育崇高使命与体操事业发展的不懈追求。存在样态践履了技术传承到活动育人的过程延伸,既有前期继承发展到本土创新的结构异化,亦有期待从内容分散到系统规划的量质协调发展,大致表现为外部引入为拓展,本土适应为创新的总体特征。治理实践历经了高度集权的行政依附到参与分权的责能转移,推动了治理主体由“同构”多元向“自主”多元的关系转变。长远来看,我国校园体操的发展要走出狭隘理论认知与实践表达的误区,基于对个体健康成长与全面发展的理念,系统规划校园体操的学—练—赛,以及平衡治理主体之间的契约合作关系,以推动校园大众性体操之扩基与竞技性体操之强基的量质协调与融合发展。
