The collection opens with John W. Loeser’s overview of classroom management techniques as they apply to common practices, such as setting clear expectations and enforcing rules and theoretical approaches, like choice theory, congruent communication, class meetings, and respectful classrooms. Loeser goes on to describe multiage classroom, a system of classroom organization in which students of varying ages and grade levels are grouped together within the same class. While this environment has been shown to have positive effects on students’ self-esteem, social interaction, and confidence levels, there is a lack of definitive research that demonstrates any specific academic benefits. Another form of collaborative learning is peer interaction, which Tricia Smith describes as a valuable way for students to help one another learn the curricular content. This method of educational organization has proven to be effective for all age groups and across all areas of education. Other peer-assistance models also exist, including student mentoring, which can improve academic outcomes for at-risk students. Team-teaching models can also drastically impact the success of a classroom, as there are two or more teachers who instruct and supervise a group of students, allowing for the enhancement of “professional growth for teachers and learning outcomes for students.”
