摘  要：文章系统分析了相比于传统线下教学，两种常见的混合式教学模式各自的优缺点，并以环境类专业课清洁生产与循环经济作为案例，具体探讨了其在实施中的学情与效果。其中两种混合式教学模式分别是线上为主线下为辅和线下为主SPOC为辅的两种模式。结果表明，混合式教学在大多数情况下优于传统线下教学，而线下为主SPOC为辅的教学模式效果更好。但对于理解、推演、计算等高阶内容，混合式教学中的线下部分和传统的线下教学都有一定的优势。从文章的学情分析可以看出，未来高校课程的教学改革中应注意针对性地分析特定的学习内容，选择不同的教学策略。

Abstract： The strengths and weakness of two common blended teaching modes were analyzed， comparing with traditional face to face teaching. Cleaner Production and Circular Economy， which is professional course of environmental specialties， was used to practice these different teaching modes. The learning situation and study effect were collected and discussed. One blended mode is based on online teaching and attached with offline teaching and discussing， while another blended mode is based on face to face teaching and attached with SPOC online teaching. The result showed that blended modes are better than face to face mode in general， while offline plus SPOC mode is even better. But in specific to high order contents， such as understanding， deducing， and calculating， face to face teaching has more advantages， which is used in traditional mode and offline plus SPOC mode. Based on this learning situation analysis， the future teaching reform in college courses need to focus on teaching strategy selection， on account of the learning contents analysis.

一、課程教学改革的背景及难点分析

在高校教学改革逐渐深化的大背景下，随着互联网的普及与相关技术的发展，以学生为主体，以问题为导向，增加多种媒介在专业课教学中的应用逐渐成为高校课程改革的大方向[1]。特别是2020年新冠肺炎疫情大爆发后，为避免人群聚集，线上教学、混合教学在高校专业课上的应用取得了爆发式增长。

随着严格管控期间的大规模线上教学，和部分城市间歇式隔离的短期线上教学，以及后疫情时期的混合式教学，积累了大量线上教学经验，同时也暴露出一些实际应用中的问题[2]。特别是学生群体在这样的教学过程中，软硬件条件和心理上的接受度，以及教学效果，有待于分析总结。……
