Using Slack in the Classroom

If you aren’t already using it, chances are you have probably heard of the online communication platform known as Slack. Slack is a cloud-based software program that is used for project management, information sharing, individual and group communication, as well as synchronous and asynchronous collaboration.  There are free and paid plans available; the main difference between the plans is the number of messages that are accessible (10,000 with the free plan) and how many third-party tools are supported (10 with the free plan).  What began in 2013 as a mode for inter-office conversation between two business offices has quickly expanded to hundreds of workplaces worldwide as well as many classrooms.

With the number of existing communication tools already available, you may be wondering how this one differs and why you might consider using it. Slack is organized into ‘channels’ which are like chat rooms dedicated to specific conversations. Messages posted to a channel can be seen by everyone who subscribes to that channel or directed to specific individuals and kept private. Unlike traditional chat rooms which may be hard to follow, Slack supports threading, which allows participants to respond directly to posts within a channel without interrupting the overall flow of conversation. Slack integrates with several third-party services, such as Box, Google Drive, and Dropbox, as well as developer platforms such as GitHub and Bitbucket. It also has a powerful search feature, making it easy to find files and specific topics in cross-channel conversations.

Slack was designed with efficiency in mind, therefore communication tends to be succinct and streamlined. Generally speaking, participants write short, direct messages closer in style to a messaging app without the ‘formality’ often used when composing an email. While this lack of formality may take some getting used to, many students are already accustomed to this style which they frequently use in various social media apps and when texting. Also unlike email, Slack follows more of an ‘opt-in’ model, where users can join in on conversations they feel are relevant and ignore those that are not.  Settings are available to determine how often users are notified of messages being posted.

The following is a list of possible ways instructors can use Slack in the classroom:

  • Share information – Create channels for posting announcements, sharing articles, links, relevant content, etc. Students can immediately ask questions or comment on the post which could lead to a dialogue around a specific topic. This may help to engage students in the topic as well as build a sense of community in the class.
  • Manage group projects – Each group can have its own channel to collaborate, share files, and communicate with each other. Instructors can post resources for groups in their specific channels and periodically check in and offer assistance as needed.
  • Crowdsource class notes – Create a channel for students to contribute main ideas from notes taken in class. This could eventually be used to create a study guide.
  • Poll the class – Slack includes a free polling tool which can be used to survey students for a variety of reasons in real-time, during class, or asynchronously, outside of class. Polls are optionally anonymous.
  • Include experts ‘in the field’ – Invite subject matter experts and/or those working ‘in the field’ to Slack so they can participate in conversations and answer student questions. JHU instructor Jennifer Bernstein invites former students to stay involved in her Slack channels so that current students can benefit from the perspective of someone who has recently graduated and is now working in the medical profession.
  • Monitor student engagement – Slack provides an optional weekly summary of usage statistics, including charts and graphs showing how many messages were posted, files uploaded, etc.

If you decide to use Slack in a classroom environment, there are some considerations to keep in mind. For example, there is no FERPA compliance in Slack. Sensitive data such as grades and personal information should not be shared in Slack spaces. Instructors should be clear with students about what types of conversations are appropriate for Slack, and what might be better served in an email or face-to-face. Another thing to consider is the capability available to members (students) that are invited to a Slack space. Instructors may be surprised with the permissions and features available to students (i.e. the ability to create their own channels). Therefore, it is recommended that instructors familiarize themselves with the established permissions of Slack before getting started.  Finally, it may be worth noting that Slack is not a course management system (Blackboard, Canvas, etc.), and does not contain many of the features available in those systems, such as a gradebook, assignment creator, rubrics tool, etc. It may, however, provide an interesting, alternative means of communication in relevant situations as determined by the instructor.

Scaffolding for Successful Learning

The Innovative Instructor likes the concept of scaffolding. Not the architectural structure,Construction workers climbing a scaffold. but the support faculty can provide for students in the classroom. Two previous posts, Scaffolding Part 2: Build Your Students’ Notetaking Skills (March 29, 2017) and Scaffolding: Teach your students how to read a journal article (February 28, 2017) looked at ways in which instructors can give students a framework to improve their skills and help them succeed. In an article in the Chronicle of Higher Education, Traditional Teaching May Deepen Inequality. Can a Different Approach Fix It?  (Beckie Supiano, May 6, 2018) instructor Kelly A. Hogan asks, “Doesn’t everybody like some structure or guidance? Why do we treat learning as something different or special?”

Ten years ago, Hogan, now STEM-Teaching Associate Professor and Assistant Dean of Instructional Innovation at the University of North Carolina at Chapel Hill, was presented with data on students’ grades in her introductory level biology class and grasped the impact that inequities in K-12 education have. “About one in 14 white students earned a D or F in the course. About one in seven Latino/a students received those grades. For black students, it was one in three.” She was directly contributing to the leaky STEM pipeline—students who failed her course were unlikely to continue in a STEM field.

Faculty may recognize the racial gaps in education that first year college students bring to the classroom. They may see these as “inevitable inequities” revealing problems that are too vast for them, as instructors, to overcome. Hogan saw it differently. The gap was her problem and she became convinced that traditional undergraduate teaching—lectures, reading assignments, high-stakes assessments—was making it worse. Specifically, students whose high schools had not prepared them for college-level work were failing, not because they weren’t capable of doing that work, “…but because no one has taught them how to navigate the system.” That includes knowing how to take notes in lectures and on reading assignments, how to prepare for writing papers and taking tests, and how (and where) to ask for help when needed.

Hogan taught courses with 300 or more students and had a lot of student data, so she could see patterns and trends. And because she also ran study-skills workshops, she had strategies that would help students succeed. She now uses a pedagogical approach called inclusive teaching. “Inclusive teaching has two main components: putting more structure into a course, giving clear instructions so that all students know what to do before, during, and after class; and thoughtfully facilitating class discussion, so that everyone can participate.”

Hogan flipped her course so that students spend class time doing active learning exercises rather than listing to her lecture. She was explicit about her motives and how students would benefit. “She emphasized the habits of a successful student and focused on the importance of practice. She broke down the things students could do before, during, and after class to give themselves the best chances of performing well. Then she made those tasks mandatory, and a factor in students’ grades.” The article details some of the practices. Her course syllabus illustrates how she communicates these to her students.

Even in a class with a 300 plus enrollment, held in an auditorium designed for lecturing, Hogan has students working in assigned groups on projects. She moves around the room to oversee their work. Students use smart phones as classroom polling devices to answer questions, opening an opportunity for discussion. Hogan facilitates class discussions in ways to equalize participation.

The article goes on to detail how two of Hogan’s “converts” have implemented inclusive teaching in their own classrooms. Hogan runs workshops on inclusive teaching that include an unusual startup activity that clearly illustrates the educational inequity gap for incoming college students. At one workshop after completing the initial task, attendees turned to what might be done to remedy the problem. “Inequity, Hogan suggested, is not intractable. Even small changes in teaching can help counteract it. ‘Adding structure to the learning environment,’ Hogan said, ‘can mitigate unfairness, build feelings of inclusion, and promote student success.’”

Changing demographics mean that many students arrive at colleges and universities lacking high school preparation that used to be taken for granted. We can’t afford to shrug off responsibility for ensuring that all of our students can succeed. As Hogan points out, the impact on our society going forward is too great. Rather, instructors must consider how to level the field and provide guidance and scaffolding to support their students in successful learning.
