In this study, H. Walberg's theory of educational productivity was used to guide a confirmatory examination of the relationship between student career aspiration and factors of educational productivity, using data from the National Education Longitudi . . .

An empirical approach is adopted in this article to explore a possible model for the prediction of students’ science achievement in China and the United States. The construction of the model was based on the ninth-grade data base from Phase 11 of the . . .

Parental influence has been identified as an important factor affecting student achievement, but the variables addressed by various parent-school partnership programs vary, and lack literature support. This deficiency was ameliorated in this study thr . . .

Student scores from the Third International Mathematics and Science Study (TIMSS) have been employed as a benchmark to measure school effectiveness in many districts across the United States. Bracey (2000) discussed the TIMSS results at the high schoo . . .

Middle school data from the Third International Mathematics and Science Study (TIMSS) are analyzed in this article to compare achievement difference between seventh and eighth grades. The statistical computing involves a selective subtraction of item . . .

Student career aspiration has been identified as the most important variable influencing students' later work experiences. The authors attempted to disentangle rela tionships among factors that influence career aspiration with in a science education c . . .

Chinese database collected from a random sample of more than 12,000 ninth-grade students in an SISS Extended Study (SES), a key project supported by the China State Commission of Education in the late 1980s, was used in this study to investigate gende . . .

The purpose of this study was to examine the effects of mathematics-related educational productivity on student career aspiration. We developed a structural model describing the relationship between educational productivity and career aspiration based . . .

The research community and American educators in general need to be aware of the methodological problems in the widely reported "learning gap" studies, Mr. Wang points out, because any misinterpretation of the results could seriously misinform the Ame . . .

A national data base from the Longitudinal Study of American Youth (LSAY) was employed to examine the effects of family commitment in education on student achievement in seventh grade science. The backward elimination procedure in the Statistical Anal . . .

School physics was transplanted from the west to China by the end of the 19th century. At the initial stage, traditional Chinese schools were filled with Confucian classics, and the classic Chinese language was too awkward to translate physics concept . . .

Hierarchical data analyses in different disciplines are reviewed to com pare statistical applications of the Hierarchical Linear Model (HLM) software and the SAS MIXED procedure. Similar features of the 2 programs are illustrated through use of the SA . . .

The test misgrading is treated in this paper as a stochastic process. Three characteristic values, the expected number of misgradings, the expected inter-occurence time of misgradings, and the expected waiting for the nth misgrading, are discussed bas . . .
