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…

We present a comment on "Benefits of completing homework for students with different aptitudes in an introductory electricity and magnetism course", by F. J. Kontur, K. de La Harpe, and N. B. Terry PRST-PER 11, 010105 (2015). Our data show that the conclusions Kontur and coworkers draw from their data may not be generally applicable.

Linking IEA's international reading assessments across 40 years is an interesting endeavor from several perspectives. Being able to examine trends in reading achievement at the 4th grade over such a long period and relate these to policy changes during that time span is an attractive idea. However, this work brings to the fore many thorny issues…

Described are the results of a formal reasoning test taken by both Japanese and American students. The most likely reasons for the difference between test score results are discussed. Japan's "hands-on" and group inquiry-oriented curriculum approach is cited as one difference. (KR)

Describes the progress made in Northern Ireland toward the introduction of GCSE science curricula in postprimary schools. Documents the move from separate courses in chemistry, physics, and biology to integrated science courses. (DDR)

Discusses the limitations of crossnational comparisons of secondary student performance in the U.S. and selected European and Pacific industrial countries, using mathematics and science data from the International Assessment for the Evaluation of Educational Achievement (IEA). Suggests the most serious problem is the rise of a new educational…

Argues that test score rankings provide little information about educational quality because countries differ substantially in factors such as student selectivity, curriculum emphasis, and the proportion of low-income students in the test-taking population. (DDR)

Identifies the problems associated with the use of dry laboratories in science education, presents design considerations for the use of such practicals in science education, and presents examples of innovative nontraditional practicals. Contains 23 references. (DDR)

The investigation reported in this paper was prompted by discrepancies between the published outcomes from two international tests of science achievement: (1) the Second International Assessment of Educational Progress (IAEP2), administered in 1991; and (2) the Third International Mathematics and Science Study (TIMSS), administered in 1995. One…
