ABSTRACT

We analyze whether non-native speakers in the classroom affect students' educational achievement and social integration. In contrast to previous studies, which mainly examine the effect of the share of immigrant pupils, we focus on language heterogeneity by using a novel measure of the degree of linguistic diversity in the classroom. Conditional on the concentration of non-native speakers in the class, the degree of linguistic diversity has no adverse effect on students' language and math skills, but worsens the social integration of non-native speakers. We demonstrate the robustness of these findings in a variety of sensitivity checks.

课堂上的语言多样性，学生的成就和社会融合

摘要

我们分析了课堂上的非母语使用者是否会影响学生的教育成就和社会融合。与以前的研究（主要研究移民学生所占份额的影响）相反，我们通过使用一种新颖的衡量教室语言多样性程度的方法来关注语言的异质性。以班级中非母语人士的集中度为条件，语言多样性的程度不会对学生的语言和数学技能产生不利影响，但会恶化非母语人士的社会融合。我们在各种敏感性检查中证明了这些发现的稳健性。
