执教七年级上册“大洲和大洋”一节,我再次研究《义务教育地理课程标准》(以下简称《标准》),它要求学生能够“运用世界地图说出七大洲、四大洋的地理分布和概况”。根据《标准》以及七年级学生的生理心理特点,我把“让学生形成七大洲和四大洋地理分布的空间观念”确定为本节课的重点和难点。形成大洲大洋分布的空间观念不仅是这节课的重点与难点,也是以后学习世界地理的基础,是学生必须掌握的基本知识和技能。回忆自己以往对于该课的教学,大致如下:教师首先引导学生 Coaching the seventh grade, “Continents and the oceans,” I once again studied the “Compulsory Education Geography Curriculum Standard” (hereinafter referred to as “the standard”), which requires students to “use the world map to illustrate the geography of the seven continents and the four oceans Distribution and Overview ”. Based on the “standards” and the physiological and psychological characteristics of the seventh grade students, I identified “the students’ concept of spatial distribution geographically distributed across seven continents and the four oceans” as the focus and difficulty of this lesson. The concept of space that forms the distribution of oceans in the continent is not only the focus and difficulty of this lesson, but also the basis for studying world geography in the future and the basic knowledge and skills students must master. Memories of their previous teaching for the class, roughly as follows: Teachers first guide students
