The big-fish-little-pond effect (BFLPE) refers to the theoretical prediction that equally able students will have lower academic self-concepts in higher-achieving or selective schools or programs than in lower-achieving or less selective schools or programs, largely due to social comparison based on local norms. While negative consequences of being in a more competitive educational setting are highlighted by the BFLPE, the exact nature of the BFLPE has not been closely scrutinized. This article provides a critique of the BFLPE in terms of its conceptualization, methodology, and practical implications. Our main argument is that the BFLPE, while having added to our understanding of the origins of self-concepts, disproportionately emphasizes one aspect of social comparison to the exclusion of many other intervening factors. In light of our critique, we suggest a broader conception of social comparison effects on academic self-concept that emphasizes a more active role of individuals in regulating their social cognition and motivation, as well as a more distinct effect of social-contextual influences. We also suggest alternative research designs that would incorporate contextual, developmental, and individual differences as potential moderators or mediators of the BFLPE.
What is the BFLPE?The big-fish-little-pond effect (BFLPE) was proposed by Marsh and Parker (1984;Marsh 1984Marsh , 1987 based on the assumption that students use a local "frame of reference" to form their self-concepts on a relevant dimension of the self. Marsh and Parker operationalized the frame of reference or standard of comparison to be school-average ability level 1 . Thus, the general theoretical prediction based on the BFLPE is that equally able students will have lower academic self-concepts in higher average-ability schools but higher self-concepts in comparatively lower average-ability schools. In plain language, whether one perceives oneself as a big fish depends on the size of the other fish (more accurately, the average size of the other fish) in the pond. The stronger the peer group as a frame of reference, the lower one's academic self-concept. By the same token, weaker peer groups lead to higher academic self-concepts.Since Marsh and his colleagues proposed the BFLPE model, numerous studies have been conducted to date (see Marsh and Hau 2003;Marsh et al. 2005;Marsh et al. 2007, for most recent studies), and the areas where the BFLPE is investigated have also been extended from academic to artistic and athletic, among others (e.g., Chanal et al. 2005). The research interest generated by the BFLPE model is largely due to its practical implications. Marsh (1987;Marsh et al. 2004) has repeatedly warned that parents who are eager to send their children to selective schools should be aware of possible negative consequences associated with the BFLPE. Moreover, based on the fact that people are constantly working in social settings that potentially provide social comparative information and salient cues for social comparison, the BFLPE shoul...
