Abstract:

Based on the online and offline teaching of chemical engineering principles course, we carried out the teaching exploration combined with online preview, flipped classroom and home exploration on the basis of cooperative group learning. This work shows the teaching mode by taking the simple calculation of the tray number of distillation column as an example. On the basis of class grouping and pre-class thinking questions, the teacher guides students to online preview and cooperative group discussion with questions, by which students' learning initiative is ignited, and the teaching effect and efficiency of offline flipped classroom are greatly improved. Through flipped classroom and cooperative group learning, students master the ideas and methods to solve the complex engineering problems in chemical engineering, and can solve the corresponding complex engineering problems. Through extending problems and post-class group cooperation, students are guided to study and explore after class, by which students' scientific research and innovation ability is cultivated. Our teaching experiences indicated that "online preview-flipped classroom-home exploration" on the basis of cooperative group learning can be used as a general teaching mode in higher engineering education with high efficiency.
