An “Active Learning” Kit: Rationale, Methods, Models, Research, Bibliography

Overview: This post compiles two previous blogs from (originally published in June 2015 and October 2017) and concludes with a bibliography of scholarship on active learning (or “radical pedagogy”).

The first blog post focuses on basic engaged pedagogy methods, some of which go back to the Freedom Schools, some extend as far back as Maria Montessori. Some come from the Occupy Wall Street movement, others from K-12 teachers, still others from medical school practices. All are based on the premise that simply asking people to “contribute” to a conversation (in a faculty meeting or in a classroom) seems open and fair but, as much sociological research shows, typically ends up replicating the values of the person in charge or privileges those from elite backgrounds who have been well-schooled in (often unspoken) social and cultural clues and capital.

The second blog post answers the question posed to me by a friend: “But how do I teach a difficult text, such as Heidegger, using activist pedagogy?”  (The good news is that Heidegger, in What Is Called Thinking?, answered this question, falling down on the side of engaged pedagogy, what he called “letting-learn.”)

Why try these methods?  (1) If your personal goal is equality in a world where inequality is structural and violent and pervasive, engaged learning allows you to restructure your classroom with equality at the core. (Here’s the adage: You cannot counter structural inequality with good will; you need to create structures designed for equality.) You cannot structure all the rest of education or society–but you can at least start with your classroom as a place in which to model a better way. 

(2) Engaged learning methods work. We’ve known at least since Ebbinghaus’s memory experiments of the 1880s that students (like all of us) forget up to 75% of the tested or “testable” content learned in a course within six days after taking a summative, high-stakes exam in a course.  Active learning–peer-to-peer explanation, exchange, individual research on the topic, and methods described below–increase retention, understanding, and applicability well beyond the test.

Structuring Equality

You cannot counter structural inequality with good will. You have to structure equality. Transforming your classroom to a more equitable, engaged space is a great way to begin–for your students and for you.

I’m often asked why I start with pedagogy, given the larger, far-reaching institutional reforms and social ambitions that The New Education, HASTAC, and the new Futures Initiative program all advocate. My answer is simple and pragmatic: If your personal goal is equality in a world where inequality is structural and violent and pervasive, you can at least start with your classroom as a place in which to model a better way.

You can do this without in any way diminishing the quality or the standards of your subject area. In fact, the research on active learning strongly suggests your students will learn more by learning how to engage the subject matter through their own research, in projects they define, and even in the very simple techniques (described here) that you can use tomorrow. The American Psychological Association calls these methods “Total Participation” not only because they are designed so that each and every student has a way to contribute but also because they strive to give students agency in their own learning. These techniques work whether you have a seminar of 16 students or a lecture hall with 600.

The professor’s role in the engaged classroom is crucial. Not only do you “scaffold” learning opportunities, but you provide expertise (not infallible but invaluable) as needed. At the end of each exercise, you can also make sure to conclude with “meta-cognition,” reflection on why and what you have just done and on what it means. You can engage students in this reflective exercise too, asking what it feels like, how the temperature in the room changes even, when power relations are reversed and the participants take a leadership role. Without reflection, students might not understand what just happened (and you might miss some of it too). Ask them what it felt like to talk through an answer with another student, not just to sit there and hear the same four classmates dominate every class “discussion” (we have the stats on how a few students dominate even in small seminars).

If you are a faculty member of color or a woman of any race, there are additional reasons why to take the lead in the meta-cognition/reflection exercise. Students (and not only white students) might assume you are not an authority rather than that you are so much of an authority that you know the best way for them to learn. (We have research on students’ different responses to faculty of different races and genders.)

Sometimes students resist active learning. Remember: they have had at least twelve years of practice/indoctrination in mastering the formal education methods where hierarchy and control displace all the complex, experience-based, interactive learning methods (i.e. the kind we all use in our lives outside of formal education when we really want to learn how to do something). Because they have been rewarded for credential-centered and teacher-centered learning in school, some will think you are trying to get out of work or pulling a fast one by having them do the thinking and taking responsibility for their own learning. Some, conversely, will feel as if they just want to know what’s on the test so they can study for it the night before and get their passing grade. They are after the credential and don’t care about the learning.

I typically note that these are extensively researched theories, practices, and methods designed to help students learn not for the test or the grade but for the best possible retention and application of complex ideas that they will use in this class, in other classes, and in their lives beyond school. And I expect some resistance. All of this is true and it is useful to state it up front.

If you are untenured, it is even useful to put some reflection on methodology into a syllabus and to cite sources. As you will see at the bottom of this blog, you can even quote Martin Heidegger to support your pedagogy. In his 1951-52 essay, “What Is Called Thinking,” the famously difficult philosopher underscored the importance of the professor being always, forever a learner rather than simply someone with the answers. He argued that “letting learn” was the true goal of higher education.

I.  Why start with pedagogy?

Four Good Reasons to Start with Pedagogy

1.    It is in your control. There are so many huge and pressing and overwhelming issues facing higher education and our society, most of which require significant changes in funding, policy, priority, reward systems, and accreditation structures–not to mention major social realignments of race, gender, sexuality, income, citizenship, and on and on. No one can accomplish all that needs to be accomplished. We all need to be working (and are working) to change structural inequalities at every level. While we’re working on transforming the world and higher education, we are not off the hook in our individual lives and in our professional practice.

The classroom is one of the least egalitarian spaces on the planet. Freire and hooks insist that it is in the traditional classroom that students “learn their place.” There is abundant research on who gets into college, who gets out, what kind of college you go to, and how all relates to income inequality, racism, and gender issues. There is also plenty of research on how little it takes (roughly 20% participation) for a teacher to believe there is “full participation” and to believe it is a “good class” where “everyone is participating.” There is also extensive research on the prejudicial ways that race and gender factor into who talks in class, gets the professor attention, is given leeway on grades, responses to queries, and more.

A professor who does not structure a classroom for equal participation replicates social inequalities (again lots of research on this), especially if the professor is white in a mixed race classroom or male with a class of men and women. Who gets to talk? Where is the teacher? Who has the knowledge? Even in seminars with “discussion,” who hogs the floor, who is the boss, who is too ashamed to speak?

Learning inside formal education is different than successful learning almost anywhere else—and it is almost universally effective at implicitly and sometimes explicitly inculcating social values: who has knowledge, who has power, what counts as knowledge, what makes “our tradition” and how does that tradition include or exclude “us.”  Epistemology, curriculum, and pedagogy are all different aspects of the same social lesson plan.

2.    It is free. You don’t need any technology to transform your classroom from a credential-centered or professor-centered environment (information and ideas emanating from you to your students) to a student-centered, interactive, engaged, research-based, goal driven, egalitarian classroom. You can use as much or as little technology as you want.  (Personally, I start with index cards. I could end there. But I also want my students to know they have something valuable to contribute to one another and to society. For that purpose, I use google docs for collaborative exercises among the students. And I use a WordPress site–such as this one–or create a Group on HASTAC, both of which are free. I show students how to write their publication into their resumes or CV’s.)

3.    It works. Soliciting what the American Psychological Association calls “Total Participation,” structuring a way where everyone in the room has a voice and has an opportunity to register an idea, is by far the most effective way to avoid “group think.” In the traditional seminar room, one person shoots a hand up first and then others either agree or dissent but that first comment directly or indirectly sets the parameters of a conversation. With inventory or Total Participation methods, everyone writes out an idea, speaks the idea, and everyone then has a full array of possible responses. There’s always an intriguing surprise that, in a traditional seminar, might never be articulated.

In the worst traditional environments (such as Board rooms with the CEO present or in community meetings with a culture of one person claiming to be the “most radical” in the room), once the most powerful person speaks there is little chance of other perspectives emerging. Structuring total participation is the best way to counter these tendencies (in classrooms, in department meetings, in civic organizations, and in corporate boardrooms; I’ve seen the techniques used with equal success at #Occupy and with groups of Fortune 100 CEOs–and in dozens of classrooms, of all sizes, in all fields).

All of the methods below are useful and there are many more in the books and articles appended in the bibliography. I’ve personally used these techniques in a group of five coworkers, in a community meeting with a dozen people, in class of 20 students, in a class of 200 students, in a lecture hall with 500 people, and in the Philadelphia 76’ers stadium with 6000+ IB high school teachers.

Also, the more you think about how giving power to others enriches everyone’s learning, lightens your own load, and makes everyone less alienated, the more you see why democracy is preferable to oligarchy. You are not just modeling a classroom practice but a social ideal. That gives meaning and affect to all the other conditions of social inequality you may want to address. However, even if you have no interest in social equality, just putting student inquiry at the center of a classroom helps everyone learn better, deeper, and more. The research of Harvard physicist Eric Mazur has demonstrated that in some stunning ways. Active learning is just better, in the short run, and models a better social role for higher education, in the long run.

4.    It is gratifying and gives you energy and inspiration for the bigger institutional battles. Social activism and institutional change are difficult. Victories should be celebrated because we need to keep our spirit up to fight against legislators cutting funding and programs and tenure; the horrific adjunct crisis that must be reversed immediately; the soaring cost of tuition and the immoral tuition debt with which we saddle the next generation; the irrelevant curriculum designed for the Taylorist era of the assembly line and not for the world we live in now; the standardized metrics that test only how well prepared you are to take standardized tests (in itself largely income based);  the soaring educational inequality that exacerbates income inequality. Etc.

There is so much work to do. So why not see your students thrive, see them enjoying their learning, see them becoming engaged in ways they were not before, see them learning and designing learning that is far more ambitious and thoughtful and deep than you had thought possible. All that is gratifying and inspiring. It is joyful. We need joy and positive energy to fight all the battles ahead.

II. Five “Inventory” Methods

The American Psychological Association calls these Total Participation methodologies:  “Teaching techniques that solicit participation and higher-order thinking from all students at the same time.”


1.    Think-Pair-Share. Approximately 5 minutes of class time; can be done at any point in a class. At some point in every class and every lecture, I use this technique I learned from a second grade teacher but have also seen in medical schools (it’s analogue is the intern surgeon’s method of “See One. Do One. Teach One.”  And then I add:  Share one.)

In Think-Pair-Share, you hand out index cards and pencils (this is not necessary but it somehow sets the mood fast and fast is impottant in TPS).

THINK: You set a timer for 90 seconds (really, 90 seconds). And you pose a question. For example, if this were a class on “Why Start With Pedagogy?” I would ask everyone to take 90 seconds to jot down three things (there are no right or wrong answers) they do in their classrooms to engage students.

PAIR: When the timer sounds, I then have students work in pairs for another 90 seconds in a very specific, ritualized way. One reads their card out loud; the other listens without interrupting. They they switch roles. Each class member then has one opportunity to speak uninterrupted and one opportunity to listen uninterrupted (an underdeveloped skill). Hearing your own voice in a classroom—and witnessing being heard—is the beginning of taking responsibility for your own learning. There is also something about the ritual of writing down, then reading to someone else, that allows the introvert to speak up in a way that avoids the panic of being called on and having to speak extemp before a group

After the pair has listened to one another, they then (still within the 90 seconds) work quickly together to edit, merge, or choose one thing they will “share,” together, with the group.

SHARE: If the group is small, I go around and have each pair read rapidly what they came up with, sticking to what is on the card, and listening to all the responses without interruption until we’ve heard from everyone. I often take notes as students read and build discussion around those points. There is always something beyond what I would have come up with on my own, always a curve ball, a surprise. In a very large lecture class, I often have a Google Doc ready and “Share” means every pair writing out their one thing on the Doc. (For more details, read Single Best Way to Transform Classrooms of Any Size.)

2.    Everyone Raise Your Hand. No extra time needed. This is an exercise developed by the great science fiction writer Samuel Delany. He never went to college and had a romantic idea of what it must be like. He was shocked when, having achieved eminence as a writer and been asked to teach his first college class, he asked a question and saw shame and fear in the faces of some of his students. As a queer African American writer, he especially felt dismay when queer and Black students shied away from answering.

His eloquent response to this failure of pedagogy is unforgettable. Delany says: “Don’t you realize that every time you don’t answer a question, you’re learning something? You’re learning how to make do with what you got, and you’re learning how not to ask for a raise…you’re learning how to take it. That’s not good! That’s not good! So, from now on, whenever I ask a question, everybody’s got to put their hand up. I don’t care whether you know the answer or not. You have to put your hand up…I’m going to call on you and if you don’t know the answer, I want you to say nice and clear: ‘I don’t know the answer to that, Professor Delany, but I would like to hear what that person has to say. And we’ll pass it on. And so this is what we started doing. And I said, whenever I ask a question, everybody put their hand up. I don’t care whether you know or not…You need to teach people they are important enough to say what they have to say.’   So now I do that, I ask everyone to raise their hand.”

So that is the “Delany method.” You ask a question and everyone raises a hand. Cognitive science tells us that even this physical gesture is a way of saying “I am here.” It changes how people feel about their worth and their right to have a place in higher education. The method works. It’s funny, it’s embarrassing, and it is also a training, a practice, in participation, in being present. It means people prepare better because they know they cannot hide behind their own shame or indifference. (A doctoral student taught me this method. A great thing about inventory pedagogy is you learn things from your students all the time, including about learning.)

NOTE:  If you are concerned about students who don’t want to participate, you can follow a practice we use of letting students take Red, Yellow, or Green dots to put on name badges before class.  “Red” means “not today” and “yellow” means “well, okay” and “green” means “I’m ready to go!”    This also gives you the chance to talk to the student who chooses “red” and find out why.   ASKING is the best active learning method of all!

3.    Question Stacking No extra time needed. I learned this method from a student, too, and she learned it from the Occupy movement. It’s an alternate way of structuring equality in the classroom to the Delany method above—and it works great in department meetings, too. To ensure no one hogs the discussion, when someone has a comment to make, you write their name down on a sheet. You go through the sheet and ask for comments. No one asks a second question or makes a second comment until everyone else whose name is on the sheet has gone first. (You can also have a sign up sheet and have students come up to the podium to sign up. Or you can have a line and answer each person in order.) Also, set a time limit of one minute per question and have a timer set. People will adjust to the time quickly. It makes a difference, sets a practice of consideration, respect, and egalitarianism in a structural way.

4.    The Exit Ticket. Three minutes of class time. End every class three minutes early—set a timer if you need to. It’s an important practice in itself, reminding oneself to end on time. On those index cards, have every student write the one question that is still on their minds at the end of the class. After a particularly vibrant or controversial class, I like to ask: “What topic did we raise today that is going to keep you up tonight? If nothing, what should we have asked that would keep you thinking into the night?” Ask that the card be full sentences. Have them sign the card. Everyone leaves with a parting thought written out carefully; it makes for deeper reading for the next class. (If you do this with a Google Doc, everyone sees the questions that remain and that causes a different kind of post-class introspection.) You as a professor can read all their questions and use that to help shape the next class period—perhaps tomorrow’s Think-Pair-Share. A friend who teaches lectures of 200-400, does this to take role and he and his TA’s use the questions to guide their smaller discussion sessions and he uses them to shape his next lecture. It is efficient, engaged, and useful on many levels.

5.    The Entry Ticket. Of course, you can also begin your next class with an Entry Ticket on which each student writes the one idea that sticks with them most from the reading assignment. Last term, a student taught me an eloquent and surprisingly moving way to do this. She has students transcribe one sentence or quote from the reading that sticks with them, either because they love it, hate it, or are confused by it. She then goes around the room and has each student read their sentence. This shows many things, including how we may think we are all reading the same text, but our attention and interests actually shape and select what we read, what we remember. It’s a fascinating way to begin a class and students tend to come much more prepared when they know they will be asked to contribute in a meaningful way.

In Freedom and Culture, John Dewey famously wrote: “The serious threat to our democracy is not the existence of foreign totalitarian states. It is the existence within our own personal attitudes and within our own institutions of conditions which have given a victory to external authority, discipline, uniformity and dependence upon The Leader in foreign countries. The battlefield is also accordingly here – within ourselves and our institutions.”

Turning the classroom from a site in which authority is modeled and rewarded to one in which there is Total Participation—where each student has a voice, agency, active participation—is an important step to turning your classroom into a site of equality and activism, not passivity.

As is the case with all democratic action, you have as much to learn from this experience as your students do.

III. Bonus:  Yes, You Can Use Inventory Methods To Teach Heidegger  (“Letting-Learn” from What Is Called Thinking?)

Adapted from How To Make #NewEducation Work In Your Classroom Today,”, October 11, 2017.

At dinner the other night, a dear friend who has read The New Education: How to Revolutionize the University to Prepare Students for a World in Flux, said, “I loved the book–but it really didn’t tell me how to teach Martin Heidegger tomorrow.” Actually, any of the methods above work to teach even the most difficult philosophical and theoretical texts. Here’s another method that would be particularly effective in this context:

KEYWORDS: Assign a Heidegger essay. Along with the essay, give students a worksheet with, say, twenty complex concepts that Heidegger uses in the essay–say, Being, Time, Temporality, Authenticity, Enframing, Being-Towards-Death, etc.; in other words, key concepts or “keywords” that philosophers of Heidegger’s work have spent time debating.

My friend has 40 students in his class. If you come up with 20 words for 40 students, have two students each work independently on coming up with a definition for the same keyword. Keep the assignment low stakes, perhaps require 100-200 word definitions at most. For the next class, have students bring in their definition of their “keyword.”

During the next class, instead of beginning with a lecture on Heidegger, have the students with the same word pair up, work on their definition in a fixed amount of time (no more than 5 minutes), and then go around the room and have each pair read their definition of the keyword out loud. Use those definitions as a point of departure for discussion. I promise, you will never have a more alert, engaged, livelier class on Heidegger.

At the end of this class, have both students sign the final definition they’ve co-authored and hand it in to you. You will be able to use these student-defined keywords as an excellent jumping off point for your next lecture on Heidegger (if you must lecture).

All of this supports (“scaffolds”) their learning. Learning (even someone as difficult as Heidegger, especially someone as difficult as Heidegger) is a process. Heidegger called this “letting-learn” in his important book, “What is Called Thinking?” (1951).

Heidegger himself noted: “The teacher must be capable of being more teachable than the students. The teacher is far less assured of his [or her] ground than those who learn are of theirs.” And this: “Teaching is more difficult than learning because what teaching calls for is this: to let learn. The real teacher, in fact, lets nothing else be learned than—learning.”
