Group work has been shown to increase grades by enhancing learning. Group work and collaborative learning encourage students to learn from each other and is based upon the learning theory of social constructivism. Because it is a more active form of learning it is also enjoyable for the students as well and meets different learning needs students might have. While not difficult using group work in your class does involve some planning on intervention on the part of the instructor.
You can use group-work with your class for one class period or for more. Group work techniques can involve technology or not involve technology. Moodle allows you to create groups and assign activities to the group. Four main techniques can be used: informal work by a group to answer a question in one class period, the think-pair-share technique, the peer collaboration technique, the jigsaw technique, or more formal groups that work on a project over several class periods. We traditionally think of group work in a face-to-face setting, but that does not have to be the case. Students can meet virtually and work as a group using simple tools such as Microsoft Teams, Zoom, etc. In the classroom, students can use whiteboards, laptops, and their phones as clickers with Poll Everywhere. Students start out answering questions individually, then turn to a neighbor or peer and then share their findings with the class.
