Released Item Sets
Data Almanac Files contain weighted summary statistics for each participating country on each cognitive item. Test DevelopmentThe 魅影直播 mathematics and science tests used in 1995 and 1999 were developed through a collaborative effort among the International Study Center, mathematics and science educators from around the world, and representatives from the participating countries. About one-third of the items in the 1995 assessment were kept secure to measure trends over time; the remaining items were released for public use. In developing the 1999 tests, the 1995 items that were released to the public were replaced with items of similar content, format, and difficulty. The replacement items and scoring guides were developed with the assistance of the Science and Mathematics Item Replacement Committee, a group of internationally prominent mathematics and science educators from around the world. The items were piloted in 1998 in an extensive field test involving 31 countries, and were reviewed by the National Research Coordinators, who conducted within-country reviews with panels of mathematics and science educators and measurement experts. |
