数学学科是抽象、概括、凝练的,它蕴涵着简约之美,理性之美。在追求课堂教学简约化的进程中,还存在着理念认同、实践跟进、模式构建等方面需要研究的课题。且以课堂观察分析诊断为途径,进一步明晰简约化课堂的特质及改进方面;以提高教师研读能力、选用教学素材能力、教学设计能力为抓手,推进课堂教学目标、教学内容、教学环节的简约化;同时以构建“学讲练三位一体”课堂模式为重点,明晰简约化课堂中学讲练三要素的核心价值取向及相互间关系,构建“先学后讲式”、“精讲精练式”、“学讲练结合式”、“操作探究式”等“学讲练三位一体”课堂教学模式。关注学生课堂学习样态,提高课堂教学实效,减轻学生课业负担,使课堂教学由简约走向优化。 Mathematical discipline is abstract, generalized, concise, it contains a simple beauty, rational beauty. In the process of pursuing the simplification of classroom teaching, there are still some topics that need to be studied in terms of ideological identity, practice follow-up and pattern construction. And to observe and analyze the classroom as a pathway to further clarify the characteristics of simplified classroom and improvement aspects; to improve the ability of teachers to study, selection of teaching material ability, teaching design ability as the starting point to promote the classroom teaching objectives, teaching content, teaching simple At the same time, we should focus on the construction of “class teaching trinity” classroom model, clarify the core value orientation and mutual relations of the three elements of classroom teaching in high school, and establish “the first lecture after class”, “fine” Speaking refined style “, ” learning to practice combined “, ” operating inquiry “and so on ” learning to practice trinity "classroom teaching mode. Pay attention to students ’classroom learning patterns, improve the effectiveness of classroom teaching, reduce the burden on students’ homework and make classroom teaching proceed from simplicity to optimization.
