针对传统课堂教学中学生综合实践不足，从而影响知识的有效内化与解决复杂工程问题能力培养的问题，提出一种“双向延伸式”翻转课堂教学新模式，具体阐述如何将自主学习延伸至课前实践，将课程考核延伸至后续综合实训，形成课前实践驱动—课堂互动教学—课后综合实训考核的闭环教学模式，详细介绍该模式在软件工程课程中的具体应用实践，并通过教学反馈与分析，验证其在提升学生综合能力及课堂教学效果方面的有效性。

To address the limitations of traditional classroom teaching, where a lack of comprehensive practical engagement often undermines the internalization of knowledge and the development of students' ability to solve complex engineering problems, this paper introduces a bidirectional extended flipped classroom teaching model. This model systematically extends autonomous learning to include pre-class practical activities and expands course assessment to encompass post-class comprehensive project-based training, thereby establishing a closed-loop teaching framework comprising pre-class practice-driven learning, interactive classroom instruction, and post-class comprehensive project evaluation. The practical implementation of this model within the context of a software engineering course is presented in detail. Furthermore, based on teaching feedback and outcome analysis, the paper demonstrates the model's effectiveness in enhancing students' practical competence, problem-solving abilities, and overall learning performance.
