Teacher Evaluation
Further to my earlier post about long-term trends in education, this article that appeared in the Houston Chronicle piqued my interest. Seems that the Houston Independent School District is ready to approve a plan to use their Texas state testing to evaluate teacher effectiveness based on their “value-added score.” Teachers could be fired for failing to improve student learning over a three- to four-year period, although every effort would be made to help teachers improve their teaching.
As you would expect, the local teachers’ union is not a happy camper. The paper quotes Steve Antley, president of the Congress of Houston Teachers: “There are so many factors that influence scores—school climate and leadership, not to mention how students woke up feeling on test day.” Oh please! Enough of the excuses. What about the most important factor in learning—the actual teaching?
The Tennessee Value-Added study showed that of all the factors affecting learning, the quality of the teaching was the most crucial:
Research conclusions utilizing data from the TVAAS database have shown that race, socioeconomic level, class size, and classroom heterogeneity are poor predictors of student academic growth. Rather, the effectiveness of the teacher is the major determinant of student academic progress.
By the way, the same “value-added score” is used to determine performance bonuses for Houston teachers. Mr. Antley doesn’t like that either. The concept of value-added is new one for Canadian educators and one that ensures better accountability so that ALL children can be expected to learn.




I guess Houston is headed for a teacher shortage since they simply don’t understand the complexity of this situation.
This is the policy you get when people just don’t understand education.
