论文摘要
挑战与一个人在协作中推动活动的权威有关。我们研究合作小组成员具有不同专业知识的协作小组内的无偿变化。我们介绍了一组三名在高科科本科生实验室工作的学生的案例研究。他们中的一个人的任务专业知识少于她的同龄人，因为缺席了一天，这减少了她在两个故事情节中的相对挑战：“追赶”和“向前迈进”。
Inchargeness is associated with one's authority in driving the activity in collaboration. We study how inchargeness changes within a collaborative group when its members have differing expertise. We present a case study of a group of three students working in an upper division undergraduate physics laboratory. One of them has less on-task expertise than her peers due to missing a day, which reduces her relative inchargeness across two storylines: "catching up" and "moving forward".
