一、模式目标教师围绕“三个维度”设计教学目标,优化课堂教学结构,提高课堂教学实效。树立学生主体意识,教师在引导学生建构知识的过程中要先学后教,少教多学,教师在具体操作时则要少讲多学,少告诉多点拨,少单维互动多立体互动。教师要尊重和欣赏每一个学生,努力使学生在课堂中人人被尊 First, the model of the target Teachers around the “three dimensions” design teaching objectives, optimize the classroom teaching structure, improve classroom teaching effectiveness.

Teachers should talk less and learn less in concrete operation, less tell multi-point dial and less single-dimension interaction. Teachers should respect and appreciate each student and strive to ensure that all students are respected in the classroom
