Some clever analytical work that links short term tactical teacher impact with long term student outcomes. Their recommendations are perhaps less well grounded than their research. The research leaves unaddressed the debate about the balance of impact of teacher versus home environment but I would suspect that if the teacher impact value is as high as this research suggests, then the home environment impact must be even greater. The analysis still leads to the conclusion that the best results are achieved by a combination of great teaching with great parenting. The results of this study probably support the following conclusion (graphically presented; VA – value added; SD – standard deviation).
