The American Statistical Association concluded recently that teachers account for about 1 per cent to 14 per cent of the variability in test scores, and that the majority of opportunities for quality improvement are found in system - level conditions.4 In other words, most of what explains student achievement is beyond the control of teachers or even schools, and therefore arguing that teachers are the most important factor in improving the quality of education is simply wrong.

Because of the improved estimation enabled by HLM, including the use of maximum likelihood and empirical Bayes estimates, interpretation of statistical results can be broadened to include a larger p - value associated with statistical tests.

The authors assess how different covariates contribute to improving the statistical power of a randomization design and examine differences between math and reading tests; differences between test types (curriculum - referenced tests versus norm - referenced tests); and differences between elementary school and secondary school, to see if the test subject, test type, or grade level makes a large difference in the crucial design parameters.

Specific provisions included scholarships and loans to students in higher education, with loans to students preparing to be teachers and to those who showed promise in the curricular areas of mathematics, science, engineering, and modern foreign languages; grants to states for programs in mathematics, science, and modern foreign languages in public schools; the establishment of centres to expand and improve the teaching of languages; help to graduate students, including fellowships for doctoral students to prepare them to be professors at institutions of higher learning; assistance for the improvement of guidance, counseling, and testing programs; provisions for research and experimentation in the use of television, radio, motion pictures, and related media for educational purposes; and the improvement of statistical services at the state level.
