“双减”政策背景下小学高年级数学个性化作业设计策略――以“多边形的面积”为例

国家发布“双减”政策,不仅为了减轻学生课业负担,更是一种长远的战略目标,其意义深远。小学高年级数学教学效率的提高,既指向课堂教学的艺术性,也指向课后练习的个性化设计。教师应理性分析作业设计中存在的诸多问题,遵循一定的设计原则,正视传统作业形式的优势和个性化作业设计的理想前景,充分利用传统作业形式,巩固基础知识,分层布置作业,拓展数学思维;利用个性化作业设计,培养学生动手能力,开阔学生思路,提升其数学素养。数学教师应该是一个设计师、引领者和实践者,要引领学生沿着个性化作业设计之路,走向数学学习新时空,汲取数学精华,收获别样的精彩。

高中生综合性作业初探

传统作业往往以操练的方式来加强学习效果 ,这既加深了学生的学习压力 ,又忽略了学生自悟习得的机会。在这种情况下根据知识的相通性而设计综合性作业是有助于学生知识结构的整体进步的。综合性作业的推行 ,使教师的教与学生的学取得了新的进步 。

Science and Sensibility： A Restudy of Snow＇s ＂The Two Cultures＂ in The Masters

Charles Percy Snow declared his influential Rede Lecture, ＂The Two Cultures＂, in 1959. In his famous lecture, he told us that the most powerful revolutionary force in the world today is science, science is essentially progressive, and the scientific culture is also a newer one. So Snow, after excluding scientific culture from the whole culture, calls the rest of the whole culture traditional culture. In his opinion, science is more important than humanities. All these ideas are faithfully reflected in his earlier literary work The Masters （1972b）. Snow＇s favor toward men of sciences in the novel is self-evident. ＂The Masters, therefore, may be considered as a political science novel rather than as a political novel＂. It was the Industrial Revolution which created our sensibility
