由我主持的一个省级教育科研课题活动形式之一:磨课。研讨主题:读懂教材。研讨内容:数与代数领域。想带领课题组教师重新审视课改背景下计算教学中的一些问题。磨课内容是北师大版三年级下册第三单元“乘法”的第二课时“住新房”一课即两位数乘两位数的不进位乘法。为了督促执教教师自己提升读懂教材的能力我和课题组其他成员没做任何的指导和帮扶工作。执教教师独立备课,有疑问可反复研读教材及教学用书,可与同事探讨,可上网查阅相关课例及计算教学方面 I chaired by a provincial education and scientific research topics one of the activities: grinding class. Seminar topics: reading materials. Discuss content: Number and algebra field. I would like to lead the task force teachers to re-examine some of the problems in the calculation of teaching under the background of curriculum reform. Grind class content is the third unit of Beijing Normal University version of the third unit of the third unit “multiplication ” the second class “live in a new house, ” a class that is two-digit by two-digit non-carry multiplication. In order to urge the teaching staff to improve their ability to read the materials themselves, I did not provide any guidance and assistance to other members of the research team. Coaching teachers prepare their lessons independently. In case of doubt, they can study the teaching materials and teaching books repeatedly. They can discuss with their colleagues and have access to the related lessons and teaching methods
