Research shows that a student achievement gap still exists. Furthermore, the achievement gap in standardized test scores between economically disadvantaged, low socio-economic status students, especially African-American, Latino, Hispanic, Native American, and their white and Asian peers is very wide. Yet, the teacher retention rate is low, and teacher attrition rate is still high among new teachers. With proper support and resources for all teachers, especially the new ones, these rates will be improved. This book is compiling and offering model effective teaching strategies and techniques that might raise the teacher retention rate, reduce the teacher attrition rate, and ultimately narrow the student achievement gap. It is an attempt to provide research-based effective teaching strategies to give new teachers support and to narrow the student achievement gap. A collaborative and supportive staff, passion, effective classroom management and environment play important roles in student learning and success. The effective model teaching strategies that are proven to have a very positive impact on student academic achievement will be introduced to all newly acquired teachers.
