TIMSS
The Trends in International Mathematics and Science Study is coordinated by the International Study Centre of the IEA (International Association for the Evaluation of Educational Achievement), located in Boston College, USA and it collects data on student achievement in mathematics and science for the 4th and 8th grades in over 60 countries. TIMSS follows a four year cycle.
In TIMSS 2003, cApStAn was asked to verify the translation of a selection of countries for which linguistic quality control had given rise to some problems in the past. In TIMSS 2007, the number of countries for which the verification of national versions was entrusted to cApStAn grew larger and, in TIMSS 2011, all national versions were verified by cApStAn.
The Translation and Adaptation Guidelines for TIMSS materials and the methodology used to document verifier interventions are carefully elaborated by IEA - and cApStAn trains its verifiers to use it in a standardized way. Each verification cycle consists of a Field Trial and a Main Survey, and includes checking identicalness of Trend items across cycles: these are to measure trends in student achievement over time and, as IEA puts it, "if you want to measure change, don't change the measure."
"If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart."
