Achievement Goals in Social Interactions: Learning with Mastery vs. Performance Goals

Little work has studied achievement goals in social interaction situations. The present experiment aimed at contributing to this matter by showing the potential of social interaction (in particular disagreement) to moderate the effects of achievement goals on learning. Participants were led to think they interacted with a partner, sharing opinions about a text that they were studying. Mastery and performance goals were manipulated. During the "interaction,” they received either disagreement or agreement from this bogus partner. Results showed that a condition in which mastery goals were induced led to better learning than a performance goal condition only when the partner disagreed. No differences between goal conditions were observed when the partner agreed. Implications for achievement goal research are discusse

Individual differences in perceived social desirability of Openness to experience: A new framework for social desirability responding in personality research

The extent to which response distortion – such as social desirability responding (SDR) – is present in self–report measures is an issue of concern and debate in personality research, as it may seriously impact such measures' psychometric indices. The present research aimed at using the social value framework to shed new light on SDR in self–report personality tests. Two studies tested the moderating role of individual differences in perceived social desirability of the Openness to Experience dimension for test–retest reliability and predictive validity of a typical Openness measure. Results support the hypothesized moderating role of perceived social desirability for improving test–retest reliability, providing the testing condition guarantees full anonymity (Study 1), and for predictive validity (Study 2). Findings are discussed with regards to SDR in personality research and the social value framework

To confirm or to conform ? Performance goals as a regulator of conflict with more competent others

International audienceDespite the fact that most competence-relevant settings are socially relevant settings,the interpersonal effects of achievement goals have been understudied. This is all the more surprising in the case of performance goals, for which self-competence is assessed using an other-referenced standard. In the present research, performance-goals are conceived as a social tool for regulating interpersonal behaviors with more competent others. In the confrontation with a more (vs. equally) competent disagreeing partner, performance-approach goals (focus on approaching normative competence) should be associated with more dominant behavior, i.e., competitive conflict regulation, whereas performance-avoidance goals (focus on avoiding normative incompetence) should be associated with more submissive behavior, i.e., protective conflict regulation. Four studies give support to these predictions with self-reported conflict regulation measures (Study 1 and 3), evaluation of models associated to self-confirmation and compliance (Study 2) and conflict regulation behaviors (Study 4). Theoretical contributions to both the literature on achievement goals and that on socio-cognitive conflict, as well as practical implications for the issue of competence asymmetry in educational settings, are discussed

Structured Cooperative Learning as a Means for Improving Average Achievers' Mathematical Learning in Fractions

International audienceIn primary school, learning fractions is a central mathematical objective. However, the mastery of basic procedures involving fractions presents a difficulty for many students. The aim of the current intervention is to introduce structured cooperative learning as means to improve students' learning, particularly for average achievers. Previous research has underscored that heterogeneous groups might be deleterious for average achievers because they are excluded by the teacher learner relationships that is likely to take place between low and high achievers students. This intervention proposes structuring interactions in order to boost the learning of average achievers in heterogeneous groups. We hypothesize that highly structured cooperative learning should improve average achievers' understanding of the content-targeted in group work as well as progress in terms of fractions learning, when compared to low-structured cooperative learning. In this intervention, 108 fifth graders worked cooperatively in heterogeneous triads (a low, average, and high achiever). The triads had to express the length of one segment using three rulers with different sub-units and respecting three mathematical skills regarding fractions. Triads were randomly assigned to a low-structured or high-structured cooperative learning condition. In the low-structured condition, no specific structure was provided. (i.e., they organized their cooperative work as they wished). In the high-structured condition, each student became an expert for one part before working in the triad and endorsed different responsibilities. The results indicated that highly structured cooperative learning favors the understanding of the targeted task, especially for average-ability students. Moreover, students at all levels progressed from the baseline test to the post-test. Indeed, low and high achievers had the same progression in both conditions, whereas average achievers progressed more in the highly structured condition. Results are discussed in terms of new teaching methods that could efficiently increase average achievers’ performances

The motivation to learn as a self-presentation tool among Swiss high school students : The moderating role of mastery goals' perceived social value on learning

Although it has been assumed that the motivation to learn - or mastery goal endorsement - positively predicts learning achievement, most empirical findings fail to demonstrate this relationship. In the present research, conducted in a Swiss high school, we adopted a social value approach to test the hypothesis that adolescent students' mastery goals do in fact predict learning, but only if these goals are perceived as highly useful for scholarly success (high social utility), and are not endorsed as a means to be appreciated by the teachers (low social desirability), a finding that has previously been observed among college students and on teacher-graded achievement measures only. Results demonstrate that in spite of potential peculiarities of an adolescent population, individual differences in mastery goals' perceived social utility and desirability moderate the mastery goal endorsement-learning achievement relation. Findings are discussed with regard to both theory development and educational practice

Improving low achievers' academic performance at university by changing the social value of mastery goals

Recent research has shown that, in a University context, mastery goals are highly valued, and that students may endorse these goals either because they believe in their utility (i.e., social utility), in which case mastery goals are positively linked to achievement, or to create a positive image of themselves (i.e., social desirability), in which case mastery goals do not predict academic achievement. The present two experiments induced high vs. neutral levels of mastery goals' social utility and social desirability. Results confirmed that mastery goals predicted performance only when these goals were presented as socially useful but not socially desirable, especially among low achievers, those who need mastery goals the most to succeed

Belief in School Meritocracy and the Legitimization of Social and Income Inequality

Educational institutions are imbued with an institutional meritocratic discourse: only merit counts for academic success. In this article, we study whether this institutional belief has an impact beyond its primary function of encouraging students to study. We propose that belief in school meritocracy has broader societal impact by legitimizing the social class hierarchy it produces and encouraging the maintenance of inequalities. The results of four studies (one correlational study, Ntotal = 198; one experiment, Ntotal = 198; and two international data surveys, Ntotal = 88,421 in 40+countries) indicate that belief in school meritocracy reduces the perceived unfairness of social class inequality in society, support for affirmative action policies at university and support for policies aimed at reducing income inequality. Together, these studies show that the belief that schools are meritocratic carries consequences beyond the school context as it is associated with attitudes that maintain social class and economic inequality
