Some blog followers might be interested in discussion-list post “Is the ‘Teacher Effect’ the Dominant Factor in Students’ Academic Gain?” [Hake (2011)].
The abstract reads:
ABSTRACT: In his PhysLrnR post Rob Spencer pointed out that Sanders & Rivers (1996) in “Cumulative and Residual Effects of Teachers on Future Student Academic Achievement” concluded that “Within grade levels, the single most dominant factor affecting student academic gain is teacher effect.” This post considers four items relevant to Spencer's post:
I . VALUE-ADDED ASSESSMENT (VAA) criticized earlier in (a) “First, Let's Fire All the Teachers!” [Hake (2010a,b)], and (b) “Value-Added Inequities: Should Value-Added Measures Be Used to Evaluate Teachers?” [Hake (2011a,b)]; and in this post by reference to (c) “Using Student Progress To Evaluate Teachers: A Primer on Value-Added Models” [Braun (2005) http://bit.ly/gZiJdH], (d) “Challenges of Value-Added Assessment” [Doran & Fleischman (2005) http://bit.ly/dF6CuB], (e) “Problems with the use of student test scores to evaluate teachers” [Baker, Barton, Darling-Hammond, Haertel, Ladd, Linn, Ravitch, Rothstein, Shavelson, & Shepard (2010) http://bit.ly/h8k5Fw], (f) The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education [Ravitch (2010) http://amzn.to/faJ9JZ].
II. SOCIOECONOMIC STATUS (SES) stressed by Bernard Ricca, who pointed to Toni Feder's 2009 Physics Today report on Marder & Bansal (2009). Their statistical-mechanics study of “Flow and diffusion of high-stakes test scores” http://bit.ly/hYbbLe indicated that: Poverty is a more powerful influence on test scores than value added by teachers and schools. The case that poverty is an overriding influence on students' classroom achievement has been forcefully argued by David Berliner in “Our Impoverished View of Educational Reform” [Berliner (2009) <http://bit.ly/ff8BVj>], and “Poverty and Potential: Out-of-School Factors and School Success” [Berliner (2010) <http://bit.ly/fqiCUA>].
III. LESSONS FROM THE PHYSICS EDUCATION REFORM EFFORT suggest that: (a) high school, college, and university courses employing “Interactive Engagement" (IE) methods result in average normalized gains g(ave)
IV. IS THE 'TEACHER EFFECT' THE DOMINANT FACTOR IN STUDENTS' ACADEMIC GAIN?" Judging from the all above:
(a) if “academic gain” means “gain in higher-level learning for U.S. K-12 students,” then the answer is: “NO! POVERTY is the dominant factor” - see ‘I’ and ‘II’ above, and the next most important factor is the degree to which ‘Interactive Engagement’ is provided by courses and teachers - see III above”;
(b) if “academic gain” means “gain in higher-level learning for students in higher education” then the answer is: “The dominant factor in promoting academic gain is the degree to which ‘Interactive Engagement’ in provided by courses and teachers - see III above.”
