Small-group instruction is when students are taught in small groups ranging from 2 to 6 students. Small-group teaching has many benefits. It is effective because teaching focuses on the needs of students, with the aim of increasing their academic skills. Small-group instruction provides students with more focused teacher attention and the opportunity to ask specific questions about what they learned.
Teachers can also use small group instruction to intervene with struggling students. In an effective and productive learning environment, small group teaching is where the essence of learning takes place. Small groups can be used for a variety of purposes and activities and can be divided into three subtypes. These are small teacher-led groups, small student-led groups, and independent small groups (which sounds like an oxymoron, but it's not, I promise).
It seems that there are a lot of concepts to consider with small groups and I think that only a lot of trial and error with greater experience will develop a great strategy for small groups.
