Bildungserfolg von Kindern in Abhängigkeit von der Stellung in der Geschwisterreihe

Based on grades in school and on parental educational aspirations the article investigates the influence of siblings' birth order on educational opportunities and educational success of elementary school pupils. It is examined whether this influence varies by social strata, i.e., whether it is moderated by the socio-economic status of parental households. Theoretical background are the resource dilution model which focuses on siblings' rivalry for scarce family resources, the confluence model which refers to the intellectual environment within families, and the family niche model which postulates effects of siblings on personality traits of children. Furthermore, status maintenance motives of parents are used to explain birth order effects. Empirical analyses are based on a study of 1369 pupils--4th graders of elementary schools--in the city of Wiesbaden, Germany. It can be shown that the birth order has negative effects on the chosen educational indicators (grades in school, parental educational aspirations). In accordance with prior research, grades of children get worse with their position in the birth order, other things being equal. The birth order also affects educational aspirations which parents hold for their children. In this context, the crucial result of the article is: When older siblings already guarantee the social status of the family in an intergenerational perspective, parents with high SES reduce their educational aspirations for younger siblings (elimination of the status maintenance motive). In families with low SES, however, parental educational aspirations for younger siblings increase, when older siblings successfully have reached higher educational credentials (social learning from role models).[PUBLICATION ABSTRACT]
