小组活动通常是以学生为中心的教学法的一个关键组成部分，但关于什么类型的小组对本科生最有益，存在相互矛盾的证据。我们调查了学生的学习成果和态度，以小组工作时，学生被分配到组使用不同的方法在一个大的招生，以学生为中心的类。我们特别感兴趣的是，如何进入类的学生在生物学能力的不同水平表现在同质或异质群体，以及什么类型的组组成形成使用不同的方法组形成。我们发现，低能力的学生有较高的学习成绩时，他们在异质组，白色中等和高能力的学生表现同样好，在这两个组类型。不同能力类型的学生在异质性小组中对小组工作的态度都较好。使用学生的人口统计学变量，先发制人地形成团体，并允许学生自我选择他们的组伙伴都产生异质能力组。与允许自我选择的学生相比，由教师组成的人口统计组的学生有更高的学习成果。因此，异质分组为我们的非专业，大招生班的学生提供了最大的好处。
Group work is often a key component of student-centered pedagogies, but there is conflicting evidence about what types of groups provide the most benefit for undergraduate students. We investigated student learning outcomes and attitudes toward working in groups when students were assigned to groups using different methods in a large-enrollment, student-centered class. We were particularly interested in how students entering the class with different levels of competence in biology performed in homogeneous or heterogeneous groups, and what types of group compositions were formed using different methods of group formation. We found that low-competence students had higher learning outcomes when they were in heterogeneous groups, white mid- and high-competence students performed equally well in both group types. Students of all competence types had better attitudes toward group work in heterogeneous groups. The use of student demographic variables to preemptively form groups and allowing students to self-select their group mates both yielded heterogeneous competence groups. Students in the instructor-formed, demographic groups had higher learning outcomes compared with students allowed to self-select. Thus, heterogeneous groupings provided the most benefit for students in our nonmajors, large-enrollment class.
