A group discussion involves more than two participants and helps develop important skills like communication, leadership, and presentation. A group is defined as three or more people working together to accomplish a task. There are different types of group members and groups, including primary, social, learning, service, and public groups. Preparing, being confident, forming debates while addressing misunderstandings, finding balance in opinions, and making decisions are some steps to being good at group discussions. Group discussions have advantages like improving knowledge, overcoming fears of public speaking, and considering different perspectives, as well as disadvantages like some participants not contributing or conflicts arising.
