Research has shown that there is no greater influence on a student's success than the quality of his or her teacher. This book presents the research findings which demonstrate the connection between teacher effectiveness and student achievement. We've always known, at least intuitively, that teachers matter, but this book proves that teachers are the most powerful factors ensuring student success. Author James Stronge describes and explains the value-added teacher-assessment research that has emerged in the past decade and demystifies the power and practices of effective teachers.
