“学案导学”教学法作为适应新课改理念而进行的一次积极有益的尝试，促进了学生自学和教师引导的紧密结合，在一定程度上利于学生自主学习能力的提高和教师教学效益的提升。但随着“学案导学”的逐步推广和发展，其最初提倡的以学生为主体的“导”学，却又逐渐演变为了教师起绝大部分主导作用的“教”学，与其最初的理想作用大相径庭。而在当今提倡学科核心素养的背景下，学案势必要成为师生教与学的助力而非束缚，因此进一步明确学案导学之“导”的核心概念、解析其陷入的误区，从而在学案设计中优化学案导学之“导”、增强导学在高中政治课堂的教育实效性，是高中政治学案改进中亟需解决的关键问题。

As a positive and beneficial attempt to adapt to the concept of the new curriculum reform, the teaching method of "learning plan guided learning" promotes the close combination of students' self-study and teachers' guidance, which is beneficial to the improvement of students' autonomous learning ability and teachers' teaching efficiency to a certain extent. However, with the gradual promotion and development of "guided learning with learning plan", the "guided learning" with students as the main body advocated at the beginning has gradually evolved into the "teaching" learning with teachers playing the dominant role, which is quite different from its original ideal role. And under the background of today's core literacy advocate discipline, study case will inevitably become the teachers and students in the aid of teaching and learning rather than the bondage, so further clear case of learning to learn "guide" of the core concepts, parsing it into the erroneous zone, and optimizing the "guide" of learning in the design of learning case, enhancing learning in high school politics classroom education effectiveness, is the key problem that needs to be solved in the improvement of high school political science case.
