In recent years, Bill Gates has given financial support to improve American education.

Late last year, the Bill and Melinda Gates Foundation1 launched2 the Measures of Effective Teaching3 project. The project tests new ways to recognize what makes a good teacher.

Its goal is to help educators and policymakers identify and support good teaching.

The study is being carried out in public school systems in seven American cities. Thousands of teachers volunteered to take part. They agreed to have their classes recorded on video, but only for observation4 by expert researchers.

Last spring, the project collected digital5 videos of thirteen thousand lessons in the classrooms taught by the teachers. They were in grades four through nine.

Researchers also collected information from students. They asked students to report their opinions of each teacher’s classroom. Students were also tested in mathematics6, English and biology.

Officials recently released7 early results of the project study. The report says teachers’ past success in raising student scores on state tests is one of the strongest signs of their ability to do so again. This is known8 as a teacher’s “value-added.”

The teachers with the highest value-added scores on state tests also help students understand math or show reading ability.

The results also say students know effective teaching when they experience it. The students gave comments on whether or not their teachers cared about them. They also gave opinions on how much teachers controlled or managed student behavior in the classroom.

The report found that classrooms where students reported positive experiences were more likely to show greater learning9 gains.

Another finding10 shows that combining different sources11 of information helps administrators12 provide better comments and suggestions to teachers. In many cases, administrators had been basing their comments on student test scores only.

The Measures of Effective Teaching project continues through twenty twelve when final results will be released. Researchers plan to test a new measure that examines what a teacher knows about how to teach a subject. Experts say these findings13 could also help create better training and development for teachers.
