In this article, we explore the relationship between the heterogeneity of secondary school classes and juvenile delinquency. The heterogeneity of school classes was measured by calculating the Herfindahl index of variety in students’ immigration background. The index was composed of three groups: natives, first-generation immigrants, and second-generation immigrants. Involvement in 13 forms of juvenile delinquency, committed during the last 12 months, was our independent variable. The offenses were grouped into minor, violent, and property offenses. The data analyzed the national class-based sample of seventh-, eighth-, and ninth-grade students in Switzerland (n = 4,158) and were collected in 2013 within the framework of the Third International Self-Report Delinquency Study (ISRD3). In general, it was found that juveniles are more likely to commit offenses when they attend school classes with higher heterogeneity, regardless of the nature of the heterogeneity (i.e., mixture of natives, first-generation immigrants, or second-generation immigrants). Within the bivariate analysis, the heterogeneity of school classes relates significantly to involvement in graffiti, vandalism, shoplifting, group fight, robbery, burglary, bicycle theft, vehicle theft, and personal theft. After statistically controlling for gender and school grade, effects of class heterogeneity persist for selected offenses.

瑞士的课堂异质性、移民背景和青少年犯罪：一项探索性研究

在本文中，我们探讨了中学班级的异质性与青少年犯罪之间的关系。学校班级的异质性是通过计算学生移民背景多样性的赫芬达尔指数来衡量的。该指数由三组组成：本地人、第一代移民和第二代移民。在过去 12 个月内发生的 13 种形式的青少年犯罪是我们的自变量。这些犯罪行为分为轻微犯罪、暴力犯罪和财产犯罪。数据分析了瑞士七、八和九年级学生的全国班级样本（n = 4,158），并于 2013 年在第三次国际自我报告犯罪研究 (ISRD3) 的框架内收集。一般来说，研究发现，无论异质性的性质如何（即本地人、第一代移民或第二代移民的混合），青少年在上异质性较高的学校课程时更容易犯罪。在双变量分析中，学校课程的异质性与参与涂鸦、故意破坏、入店行窃、群殴、抢劫、入室盗窃、自行车盗窃、车辆盗窃和个人盗窃显着相关。在对性别和学校年级进行统计控制后，班级异质性的影响对选定的罪行仍然存在。学校课程的异质性与参与涂鸦、故意破坏、入店行窃、群殴、抢劫、入室盗窃、自行车盗窃、车辆盗窃和个人盗窃有很大关系。在对性别和学校年级进行统计控制后，班级异质性的影响对选定的罪行仍然存在。学校课程的异质性与参与涂鸦、故意破坏、入店行窃、群殴、抢劫、入室盗窃、自行车盗窃、车辆盗窃和个人盗窃有很大关系。在对性别和学校年级进行统计控制后，班级异质性的影响对选定的罪行仍然存在。
