This Communication summarizes one of the invited papers to the Select 2016 BCCE Presentations ACS CHED Committee on Computers in Chemical Education online ConfChem held from October 30 to November 22, 2016. The supplemental instruction (SI) model has come a long way from being a peer-assisted study sessions geared toward improving student retention and success. Students now have 24/7 access to handouts, professional tutoring by an SI leader, and group collaboration outlets; several of these services are offered via social media sites. How well these outlets are incorporated into the classroom is now a key component of what makes an SI session successful. With the advent of these innovations, the limits to what the SI leader can provide to their students are far fewer. Some of these innovations include (but are not limited to): video lectures, practice exams, and promotion of group collaboration among students. Through the use of platforms including Facebook, Twitter, Piapp, and Slack, the SI session can be held almost exclusively online and provide just as much if not more benefit to the students involved.

ConfChem会议（2016年精选BCCE演讲）：不断变化的角色，应对时代的变化—社交媒体和辅助讲师的发展

本交流总结了2016年10月30日至11月22日在ConfChem网上举行的Select 2016 BCCE Presentations ACS CHED计算机化学教育计算机委员会邀请论文之一。补充教学（SI）模型与同行相比已经走了很长一段路协助的学习课程，旨在提高学生的保留率和成功率。现在，学生可以24/7全天候获得讲义，由SI负责人提供的专业辅导以及小组协作的渠道。其中一些服务是通过社交媒体网站提供的。现在，如何将这些渠道整合到课堂中成为确保SI课程成功的关键因素。随着这些创新的到来，SI领导者可以提供给学生的东西的限制越来越少。其中一些创新包括（但不限于）：视频讲座，练习考试，促进学生之间的小组合作。通过使用包括Facebook，Twitter，Piapp和Slack在内的平台，SI课程几乎可以完全在线进行，并为所涉及的学生提供甚至更多的好处。
