摘要：如何避免在课堂教学中重复学生的已知知识浪费时间？如何快速发现学生前期知识？如何快速发现、填平信息差，且步步推进、推陈出新，使得学生快速地见齐于师？兹分享笔者长期揣摩出来的一套教学法——耗竭式教学法，它暗合教育的导出性特征，开放性高、实战性强、挑战性高、互动性强、效果显著，适合每天操作或公开课。本文以译林牛津版高中英语一册中的Looking Good, Feeling Good 改版前后的两课中“瘦”字的表达法为例来演示如何在教学过程中进行三层推进、两重跟进。首先，我们先以互动式挑战式耗竭学生的前期知识，然后逐一耗竭教师层面的新知、学术共同体层面的三层新知，最后通过被动记忆和主动运用两层跟进强化，形成一个完美闭环，可确保教学中的信息差和教学效度。

Title: Efficient Classrooms Driven by Information Gap: Theorizing and Implementing the Exhaustive Teaching Method
Abstract: How can teachers avoid wasting classroom time by reiterating what students already know? How can instructors quickly identify students’ prior knowledge and pinpoint existing information gaps, then efficiently bridge those gaps while continuously advancing and innovating—thereby enabling students to rapidly reach the teacher’s level of understanding? This paper presents the “Exhaustive Teaching Method,” a pedagogical approach the author has refined through years of practice. Aligned with the elicitive nature of education, this method is highly open-ended, practice-oriented, challenging, and interactive, yielding remarkable results in both daily instruction and public demonstration lessons. Using the treatment of the concept of “thinness” in the pre- and post-revised versions of the unit Looking Good, Feeling Good from the Yilin Oxford High School English textbook (Book 1) as a case study, the paper illustrates a three-tiered instructional progression coupled with dual reinforcement strategies. First, through interactive and challenging activities, students’ existing knowledge is deliberately “exhausted.” Next, new knowledge is introduced and exhausted at three successive levels: the teacher’s perspective, disciplinary insights, and scholarly consensus. Finally, learning is consolidated through two layers of follow-up—passive retention and active application—creating a closed-loop system that ensures both effective gap-filling and high instructional efficacy.
