The benefits of active learning have been supported time and again in the literature. By comparing student learning gains in introductory physics courses, Richard Hake was able to show that interactive courses were over two times as effective in promoting conceptual understanding as compared to traditional ones (Hake, 1998). A more recent meta-analysis by Freeman et al. reported results from 225 studies across STEM disciplines, comparing traditional lecture to active learning (Freeman, 2014). In general, students’ average exam scores were shown to improve by around 6% in active learning classes. Additionally, students involved in traditional lecture were found to be 1.5 times more likely to fail as compared to those in classes with significant active learning.
It takes time and creativity to effectively incorporate active learning strategies into teaching and achieve the full benefits across instructional settings and disciplines. But as many of the faculty members we profile demonstrate, active learning can easily and effectively be incorporated into existing courses and materials without the need for a dramatic overhauling of the course.
Benefits of Active Learning
1.Four slave screens on the master screen
Through the drag function of the main screen, the teacher can display multiple group screens on the main screen at the same time. The main screen can display the screen images of 4 groups at the same time.
2.Screen broadcasting
The teacher can push the main screen to each group screen in the form of broadcast.
3.Multi-screen interaction
The teacher can drag the screen of a group on the main screen, and at the same time, broadcast the main screen to other groups for sharing the same screen.
