Test motivation in the assessment of student skills: The effects of incentives on motivation and performance

Abstract

There is widespread concern that assessments which have no direct consequences for students, teachers or schools underestimate student ability, and that the extent of this underestimation increases as the students become ever more familiar with such tests. This issue is particularly relevant for international comparative studies such as the IEA’s Third International Mathematics and Science Study (TIMSS) and the OECD’s Programme for International Student Assessment (PISA). In the present experimental study, a short form of the PISA mathematical literacy test is used to explore whether the levels of test motivation and test performance observed in the context of the standard PISA assessment situation can be improved by raising the stakes of testing. The impact of (1) informational feedback, (2) grading, and (3) performance-contingent financial rewards on the personal value of performing well, perceived utility of participating in the test, intended and invested effort, task-irrelevant cognitions, and test performance are investigated. The central finding of the study is that the different treatment conditions make the various value components of test motivation equally salient. Consequently, no differences were found either with respect to intended and invested effort or to test performance.
