高效课堂是有效课堂的最高境界,高效课堂基于高效教学,只有教学效率最大化且效益最优化,高效课堂才能得以实现。由此可见,要想课堂高效必须立足于课堂教学,笔者以人教版初中历史八年级上册第13课"红军不怕远征难"的教学案例为例来谈谈构建初中历史高效课堂的策略。 相似文献

正高效的课堂是和谐的课堂,而和谐的课堂是"静"与"动"辩证统一的。所谓"静",指的是倾听,包括师生间的相互倾听、学生间的相互倾听;所谓"动",指的是善于表达,包括教师的精确表达和学生的积极表达。传统教育模式导致学生养成的学而不思、思而不疑、疑而不问的陋习一时还难以根除,笔者认为这主要由于我们课堂教学中对倾听、表达、质疑的处理还不合理。前不久,笔者担任县初中历史优课评比活动的评委,听了几位教师的比赛课,课题为人教版 相似文献

Particle image velocimetry (PIV) experimental results of wake flow structure of a NACA0012 airfoil with small attack angle mounted above water surface are introduced.The experiment was carried out in a small-scale wind-wave tunnel.The diameter of wind-wave tunnel test section is 1.7 m (long) × 0.4 m (width) × 0.4 m (height).The flow fields around the airfoil were measured under four diffierent conditions by varying the distance between the airfoil and the water surface.The attack angle of the airfoil was kept 10- during the experiment.For each experimental condition,the time series of particle images was captured to calculate continuous evolution of the velocity fields.The velocity fields were ensemble averaged to get the statistic parameters such as mean velocity and vorticity.Typical instantaneous velocity fields for each case are introduced to show the basic flow structure of wind surface flow separation.The aerodynamic loads acting on the airfoil are analyzed qualitatively according to the mean vorticity distribution in the flow field based on the theory of vorticity aerodynamics.The results indicate that the flow structures and drag/lift force of the airfoil alter remarkably with the changing distance between the airfoil and water surface. 相似文献

课堂提问是师生课堂平等交流和对话的主要方式。历史课堂的有效提问能引起学生学习兴趣,能激发学生对历史知识主动探究的情感,能引领学生广涉博览,产生追究历史成因的动机,从而提高教学质量。笔者尝试从历史课堂教学的角度寻求有效提问的策略。一、设置问题新颖,注重趣味性课堂有效提问首先需要注意内容的新颖别致。新颖别致的问题会使学生产生浓厚的探索兴趣,积极思考,主动探 相似文献
