Education statistics are rarely neutral; those who collect and analyze them have different purposes. In this article, Bracey discusses several principles of data interpretation to help educators avoid falling into statistical traps. For example, because such reports as A Nation At Risk contain many "selected, spun, distorted, and even manufactured…

Continues the discussion about the Third International Mathematics and Science Study results. American eighth-grade students are on a par with science students in New Zealand, China, Iceland, and Bulgaria. Meanwhile, one researcher found that all of the top six countries in TIMSS math had centralized curricula. None relies heavily on tests. (MLH)

When critiquing a 1992 IEA study of reading in 31 nations, Herbert Walberg unfairly panned U.S. reading instruction, considering that American 9-year-olds finished second and 14-year-olds tied for eighth place. Apparently, "progress" was down for high-scoring countries. Two UCLA researchers discovered that the Los Angeles student…

Alan Krueger's reanalyses of Eric Hanushek's school-productivity data show that Hanushek's "money doesn't matter" conclusions (influential in several states' education-finance hearings) have no factual basis. Hanushek excluded Tennessee's student/teacher ratio study (Project STAR). Also, class size is influencing students' success in…

Productivity growth (and its connections with schools) may be mysterious, but experts continue to document an expanding U.S. economy. A University of Wisconsin study described in the Fall 1999 "ERS Spectrum" found a mismatch between teachers' actual and recommended grading practices. Maybe the literature is unreasonable. (MLH)

A research psychologist and education consultant offers school board members some principles for appraising statistics: (1) distinguish between rates and numbers; (2) distinguish between ranks and scores; (3) try to "look through" the pictorial representation of data; (4) double check the data for accuracy; and (5) consider the source of the data.…

Given only correlation coefficient, one cannot infer causality. This lesson has been lost on Secretary of Education Richard Riley, who recently intoned that "taking rigorous mathematics courses ... early in secondary schools is a gateway to college and future employment." Students taking such classes have probably already been identified…

A University of Michigan study that surveyed students about sexual harassment behaviors discovered that 83% of girls and 60% of boys have experienced harassment. Also, 75% of the victims had also been perpetrators. Another study examined how cultural influences may affect high-achieving Japanese students' use of will power and memorization…

Disagrees with research showing that socioeconomic status has little impact on parental involvement in children's education. From the author's own experience, working-class parents are as concerned as affluent ones about children's progress, but have less energy/time for participation. In other research, a new assessment instrument may help…

Two researchers who re-examined a North Carolina district's exemplary SAT performance discovered that this district's gains paralleled those in the rest of the state. The dropout rate also remained high. Most investigations of music, art, and academic learning show positive correlations, but no causal effects. (MLH)

Two University of Missouri researchers say much econometric research on the money/achievement connection is deeply flawed. Data from the "School District Data Book" and Second International Mathematics Study show that money's impact is enormous. In other research, principals' high expectations are pivotal, and children's drawings are…

Eric Hanushek's conclusion that money does not matter in public education is debatable. His latest meta-analysis reviews many articles from economics journals, while omitting several published in education journals. He finds no relationship between test results and spending, yet labels schools inefficient. In other research, the Annie Casey…

International comparisons of academic achievement are faulted by methodological problems. U.S. schools are doing better in international comparisons than we have been led to believe. However, there are shortcomings. An education reform agenda needs to treat poor urban and rural schools as patients in an intensive-care ward. (MLF)

Reviews research conducted to determine if learning to program in Logo has a positive effect on other aspects of thinking, based on Seymour Papert's findings on Logo. The appropriateness of research on Logo and programming is discussed, and research studies involving elementary and secondary school children are briefly described. (LRW)

Reviews results of studies concerned with the effects of computer-assisted instruction on secondary students in the areas of academic achievement, motivation, and social development. Discusses a report on such findings which employs the research technique of meta analysis to translate measured research findings into standard units of effect. (JJD)
