This rejoinder keeps the original focus on statistical computing pertaining to the correlation of student achievement between mathematics and science from the Trend in Mathematics and Science Study (TIMSS). Albeit the availability of student performance data in TIMSS and the emphasis of the inter-subject connection in the Next Generation Science…

Professional development for teachers has been a substantial issue in contemporary educational research and policy. Yet, opportunities for professional development activities have been very limited in Turkey. In this study, we examined Turkish teachers' involvement in professional development activities by comparing their participation with the…

The purpose of this study was to examine the impact of dimensionality, common-item set format, and different scale linking methods on preserving equity property with mixed-format test equating. Item response theory (IRT) true-score equating (TSE) and IRT observed-score equating (OSE) methods were used under common-item nonequivalent groups design.…

Since its inception, the National Center for Education Statistics (NCES) has been committed to the practice of documenting its statistical methods for its customers and of seeking to avoid misinterpretation of its published data. The reason for this policy is to assure customers that proper statistical standards and techniques have been observed,…

Students' attitude towards science (SAS) is often a subject of investigation in science education research. Survey of rating scale is commonly used in the study of SAS. The present study illustrates how Rasch analysis can be used to provide psychometric information of SAS rating scales. The analyses were conducted on a 20-item SAS scale used in an…

The 2012 edition of the "Digest of Education Statistics" is the 48th in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

This study comes at an opportune moment for Japanese and U.S. educators, policymakers, and researchers given the trends of global policy and equity-based reform. Discussions of academic achievement in both societies allow us to examine accessibility in mathematics education in order to best prepare teachers to serve the needs of students.…

The 2011 edition of the "Digest of Education Statistics" is the 47th in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

In this study, we investigated gender and minority achievement gaps on 8th-grade science items employing a multilevel item response methodology. Both gaps were wider on physics and earth science items than on biology and chemistry items. Larger gender gaps were found on items with specific topics favoring male students than other items, for…

U.S. students have consistently lagged behind their peers in other nations on international science assessments--a performance increasingly at odds with the challenge of being able to live and compete in a global environment, powered by innovations in science, engineering and technology. A strong foundation in science is clearly critical if…

The Government is committed to ensuring that the new National Curriculum compares favourably with the curricula in the highest performing jurisdictions, and sets rigorous requirements for pupil attainment which measure up to the highest standards set internationally. The Government is also committed to slimming the National Curriculum so that it…

Discusses how responses to multiple-choice items could be interpreted, demonstrates how responses on constructed-response items can be analyzed, and examines interactions between item characteristics and student responses. Uses information, specifically items and student responses, from the Third International Mathematics and Science Study…
