语文教师肩负着传授传统文化的重要任务。传统文化的学习分为了解、掌握、内化三个阶段,每个阶段的教学重点与方法都不同。在了解阶段,教师要带领学生初步感受传统文化的形式与内容;在掌握阶段,学生要学会自主鉴赏文章,领会文化精神;在内化阶段,学生要将自己了解和领悟到的精神真正吸收,形成正确的三观,以更好地指导学习与生活。 相似文献

为厘清我国体育教师培养研究的整体态势、研究现状与前沿演进,本文运用CiteSpace软件以关键词、作者、机构为节点对1705篇相关文献进行可视化分析和共性研究,并对关键词进行类聚分析、时间演化分析,绘制相应的可视化图谱,梳理该领域研究趋势,探寻体育教师培养规律。结果表明:(1)我国体育教师培养相关领域研究的发文量呈波动状态;(2)我国相关领域作者之间合作关系结构总体较为松散;(3)大学研究机构仍然是体育教师培育研究的主阵地;(4)体育教师培养相关研究领域的前沿研究方向集中于“课程体系”“学校体育”“幼儿体育”“专业发展”“健康中国”“专业标准”。建议:今后体育教师培养研究应注重核心学者领衔,强化学术团队的使命,构建相关多元比较研究,以此促进研究经验相互融合与借鉴。 相似文献

The joining of aluminum alloy sheets with thickness less than 2.0 mm is difficult via conventional frictionstir welding owing to the defects in the joint, such as root flaw, keyhole and lazy S. In the present research, a newlydesigned pinless tool with involute grooves on its shoulder surface was applied to weld 1.5 mm thick AA2024-T3. Theeffects of the rotating speed and welding speed on the microstructure and mechanical properties of the joints were analyzed.The experimental results showed that the root flaw and keyhole were successfully eliminated. The lazy S wasalso eliminated under the optimized welding parameters. The maximum tensile strength of the joints was 326 MPa,which is about 74.1% that of the base material. Moreover, all the tensile samples fractured from the retreating side.Two fracture modes were observed during the tensile tests, which are related with the lazy S. 相似文献
