The authors outline the application of latent class analysis (LCA) to classroom observational instruments. LCA offers diagnostic information about teachers' instructional strengths and weaknesses, along with estimates of measurement error for individual teachers, while remaining relatively straightforward to implement and interpret. It is…

To ensure accurate interpretation of research findings, researchers should report details about their research design, data collection method, and response rates when presenting findings from survey research. A review of 100 peer-reviewed articles reporting the results of survey research on K-12 schools with principals as the designated…

Argues that IQ tests work only for some people some of the time. Offers a theory that emphasizes the roles in intelligence of information-processing, the environmental context, and coping with novelty and automatization of task performance, as a possibility for improving levels of prediction. (CMG)

The authors of this article examine the analytic and reporting features of research articles cited in "Studying Teacher Education: The Report of the AERA Panel on Research and Teacher Education" (Cochran-Smith & Zeichner, 2005b) that used quantitative reporting practices. Their purpose was to help to identify reporting practices that can be…

The National Assessment of Educational Progress (NAEP) must use sampling techniques that produce data which are representative on national, state, and local levels. The validity of findings is enhanced when state and district comparisons are made. Multiple measures will allow the diagnosis of strengths and weaknesses. The data should be…

Questions the adequacy with which the giftedness construct is defined in applied educational settings, and the adequacy of the validation data available for these gifted identification procedures. (Author/BJV)

Summarizes and challenges criticism that the behavioral sciences have failed to produce long-lasting generalizations due to cultural and historical relativism and interaction effects. Using findings from meta-analysis, the author argues that considerable consistency and validity across contexts of many generalizations exists, as well as promising…

Discusses issues involved in the construction, validity, and use of tests that evaluate educational progress, especially those that assess higher-order cognitive functioning. Reviews the four articles in this special issue. (FMW)

Argues that the clinical trial paradigm is the wrong model for educational research. Interpretive case study research suggests that the best thing policymakers can do for educational improvement is to give local educators and school communities more freedom and funding to work out their own ways to improve practice. (SLD)

Educational researchers are not engaged in discovering mechanistic universal truths sought by positivists or tidy prescriptions about what works. Instead, they provide guidelines and interpretive material to liberate the teacher's intelligence so that the teacher can use whatever ability he or she can achieve. (SLD)

Because of the importance of standardized test scores in current definitions of educational achievement, pressure to raise test scores has affected their accuracy. Examines the causes of two major sources of test score pollution and their impact on education. Discusses the ethical status of documented test-preparation activities. (CJS)

Explores the cumulative impact of repeated standardized testing on student attitudes and motivation. By high school, a large number of students, especially low achievers, become disillusioned about tests, are less motivated to give genuine efforts, and increasingly use inappropriate test-taking strategies, undermining test validity and genuine…
