The Third International Mathematics and Science Study (TIMSS) involved 47 countries, thousands of students, and their teachers and schools. Included in the battery of tests and other instruments was a Student Questionnaire that was concerned with the personal and school contexts of the students in relation to their mathematics and science learning. Quite late in the planning of this very expensive study, it transpired that no country had considered gathering data on the students' sense of the relevance of the science topics in the achievement tests, of their science learning, or, their metacognitive awareness of this learning. This paper reports one last minute attempt to collect these data from one group of student in Population 3 - the students in the final year of schooling. Like many other aspects of TIMSS, the psychometric dominance in its design meant that this study was logistically very difficult, but some interesting findings are reported.
