【摘 要】分层教学模式,包括分层自选学习、合作探究学习、自主设计作业、分层多元评价等四个步骤,在这四个步骤中,教师和学生都是主体。在分层自选学习中,教师为学生提供可供选择的资源,引导学生自主学习;在合作探究学习中,教师布置探究任务,引导学生在小组中合作逐层解决问题;在作业训练环节,教师为学生提供范例,组织学生依据能力自主地设计作业;在分层多元评价环节,教师以学生的分层为基础,引导学生对学习过程进行互评。

【Abstract】The hierarchical teaching model includes four steps: hierarchical self-selected learning, cooperative inquiry learning, self-designed homework, and hierarchical multiple evaluation. In these four steps, teachers and students are the main body. In hierarchical self-selected learning, teachers provide students with alternative resources to guide students to learn independently; in cooperative inquiry learning, teachers assign inquiry tasks to guide students to cooperate in groups to solve problems layer by layer; in homework training, teachers Provide examples for students and organize students to design homework independently according to their abilities; in the hierarchical and multi-evaluation link, teachers guide students to make mutual evaluations on the learning process based on students stratification.

分層教学是一个教学概念,近些年备受各学科教师的重视。要在教学中有效应用这一模式,教师就要结合所处的教育环境,充分利用拥有的教学资源,进行特色的教学计划设计。分层教学是循序推进的教学活动,包括学生自学、教师引导深入学习、习题训练与设计、总结反思与评价等环节。教师在这些环节中要为学生提供学习资源、范例资源,然后对学习秩序进行引导和维护,如此便可以让学生在激发主观能动性的情况下进行分层学习。
一、引入微课资源,开展分层自选学习活动
自主学习是分层教学模式的第一环节,也是教师引入微课资源、开展分层自选学习活动的环节。在将学生分成后进、提升、拓展三个层次后,教师可以为这三个层次的学生提供不同的资源,将微课划分成三个部分,第一部分供全体学生,第二部分供提升和后进层,第三部分供后进层。……
