Abstract, Value orientations are believed to influence learning in school. We assume that this influence is mediated by the valences attached to specific school subjects. In a questionnaire study (704 students from 36 classes) achievement and well-being value orientations were measured. Students also rated valence scales for the school subjects German and Mathematics and reported their respective grades. In order to take into consideration the nested data structure, the mediation hypotheses were tested using the Hierarchical Linear Model in a series of intercept only models. School grades were significantly predicted by value orientation. A mediation analysis indicated that this relation was completely mediated by the valences of the different school subjects.

Les orientations valeurs sont supposées influencer l'apprentissage. Nous croyons que cette influence est médiate par les valences des disciplines scolaires. Dans un sondage (704 étudiants de 36 classes) les orientations des valeurs de réussite et de bien-être ont été mesurées. En outre, les étudiants ont indiqué leur valence pour les disciplines d'allemand et de mathématique et communiqué leurs notes respectives. Pour tenir compte de la structure imbriquée des dates, les hypothèses médiatiques ont été analysées en utilisant le Modèle Hiérarchique Linéaire avec des models intercept-only. Les notes ont été prédites de façon significative par les orientations valeur. L'analyse de médiation indique une dépendance strictement médiate par les valences des différentes disciplines scolaires.

Key words: Academic achievement, Hierarchical linear model, Mediation analysis, Valence, Value orientation.
