Can a Class Be Too Small?

In his book, David and Goliath: Underdogs, Misfits, and the Art of Battling Giants, Malcolm Gladwell opens a can of worms when he asks the question, "Can a class be too small?" When it comes to the number of students in a classroom, most of us assume smaller is better. I know I do. The low student-to-teacher ratio makes sense to me intuitively: the fewer students a teacher has in his or her class, the more individualized attention each student would receive.

And yet, Gladwell argues that "The small class is potentially as difficult for a teacher to manage as the very large class size." To test his theory, Gladwell polled a large number of teachers in the United States and Canada. In David and Goliath, he quotes some of those teachers as they offer plausible explanations for why small class sizes are problematic:

• Interactions are too intense. While there are, presumably, fewer interactions in a small class for a teacher to manage, the interactions that do occur are more difficult to handle. "There is simply no way for the cantankerous kids to get away from one another." There's no place for students to hide. According to one teacher, "the students start acting 'like siblings in the backseat of a car.'" 
• Insufficient "critical mass" for discussions and group activities. As a middle school teacher explains, "students are awkward and self-conscious and anxious about seeming too smart. Getting them to engage . . . can be 'like pulling teeth.'" Also, as one teacher states, "It's difficult to play games . . . the  momentum just isn't there." 
• Lack of peers at a similar academic level within a class.  In a really small class, it is harder to find others who are just like you. There are no subgroups. Complains one teacher, "The chances that children are surrounded by a critical mass of other people like them start to get really low." As one teacher explains: "What you need [as a student] is to have people around you asking the same questions, wrestling with the same issues, and worrying about the same things as you are, so that you feel a little less isolated and a little more normal." 
• Lack of diversity in discussions. Fewer students means fewer (if any!) participants in a discussion. If the group is too small, "it's like they have a muzzle on." 

The magic number for class size, according to the teachers Gladwell polled, seems to be between 18 and 30 students. Since I have trouble understanding why a teacher would actually prefer to work with so many students at one time, I would like to contrast my experiences as a homeschooler with the experiences of the teachers Gladwell interviewed. The main question I'm attempting to answer is this:

Exactly what is it about certain settings—in particular, the various discussion-based classes that are taught by homeschooling parents like myself—that makes small class sizes desirable?  

(Although my response is necessarily based on my experiences as a home educator, I imagine there are many other situations where small class sizes are preferable, too.)

Not Close Enough: Using Google Hangouts for Group Discussions

As I type this, my son and his friends are using Skype to rehearse lines for their production of Shakespeare's "King Lear." This afternoon's practice was cancelled due to icy roads, and given how difficult it usually is to reschedule, an alternative was sought. While the kids can't do anything about the vagaries of New Hampshire weather, new technologies provide a reasonable alternative to meeting in person.

For those who are new to Skype and similar video-chat tools: video chat is faster than email, more personal than instant messaging, and cheaper than long-distance phone calls. Note: "video chat" refers to a one-on-one conversation; video conferencing is conducted with a group.

Google Hangouts uses a multi-user video chat room viewed through a browser. A few weeks ago, I made my first attempt at using Google Hangouts. According to the website, you can "video chat with up to nine friends." Perhaps I was naive, but I thought I would be able to see video images of all the people with whom I would be chatting (as this Google+ video implies). As it turns it, "your 'mileage' may vary."

Getting Started with Google Hangouts, April 2013

My goal was to hold a dynamic class discussion, where everyone would have a chance to talk and contribute, as they do during our usual face-to-face meetings. Of the seven people who participated in our Google Hangout, two were in the same building and five joined from remote locations. We quickly discovered that having two computers in close proximity distorted the audio significantly. To stop the annoying feedback and reverberations, we turned off the audio on one of the computers. That seemed to solve the problem.

Social Learning: Deciding to Host a Study Group

We all have a basic human need to connect with others. Spending too much time alone is detrimental to our emotional, spiritual and psychological well-being. We're all aware of this, and so we make an effort to get out and meet people. As parents, we arrange "play dates" for our children and take them to social gatherings. As homeschoolers, we actively pursue opportunities for meeting and keeping in touch with other homeschooling families. Usually, friendship and a sense of community are the main goals, but there's an added benefit: "social learning," or learning through collaboration and discussion within a group. Studies have shown that learning with others is good for our intellectual development. As John Seely Brown and Richard Adler write in their article, "Minds on Fire" (Educause, 2008):

". . . our understanding of content is socially constructed through conversations about that content and through grounded interactions, especially with others, around problems or actions. The focus is not so much on what we are learning but on how we are learning."

What does this mean to us, as educators? It means we need to remember that studying and socializing are not necessarily separate things to be done at separate times. Like chocolate and peanut butter, they go better together. It isn't enough for kids to get together to play after all their studies are done. They also need opportunities to learn with, and from, each other.

Social Learning: From Play Dates to Study Groups

"What about socialization?" is a question every homeschooler is asked, usually more than once. The question is so ubiquitous, books about homeschooling typically include a section devoted to the topic (as one example, see Addressing Homeschool Socialization in Homeschooling for Dummies). Homeschoolers soon learn to ask for clarification: Is the questioner asking whether their homeschooled children have any friends? Or are they worried that their children will become social misfits? By now, enough research has been done to put both of these questions to rest (see Socialization: A Great Reason Not to Go to School by Karl M. Bunday), and my own experience during the past two decades supports the prevailing research: homeschooled kids enjoy a reasonable social life and possess decent social skills.

By the time they are three or four years old, kids show an interest in making friends. So, when my kids reached that age, I found or formed playgroups and arranged "play dates" for them. As they got older, I drove them to social activities: dance, music and art classes; book groups; scout meetings; science workshops; homeschool group "field trips" and science fairs; special days at nature centers, science museums, and historical landmarks. There was rarely a shortage of things to do or people to meet, and socialization wasn't a big concern.

I noticed a change, though, at around the age of 10 or 12. There were three new developments:

1. My kids began to crave meaningful, lasting relationships with a group of their peers. It wasn't enough for them to participate in large group activities with kids of all ages. Although those activities were fun, opportunities to make friends and "really talk," one-on-one, tended to be limited. 
2. They became more selective about their friendships. Unlike younger children, who seem willing to play with almost anyone they meet, my preteens wanted to spend time with people who were special to them in one way or another. They needed to find their "tribe." As they connected with a handful of friends who shared similar interests and a passion for life and learning, they favored time with those friends over other opportunities for "socializing." 
3. They wanted company during the long hours their more in-depth studies now required. They wanted to engage in serious conversations about what they were studying, and it was more interesting to learn with friends.

It was at this point that a handful of parents and preteens got together to brainstorm ways to combine academics with socializing. Without ever having heard of "social learning," we helped our kids form various study groups (book clubs and poetry workshops; cooking, sewing, science, and history classes). Most groups met once a week. The format usually included an adult mentor (one of the parents or an outside tutor) and four to eight kids whose ages were within a few years of each other. When it came to participating, maturity level mattered more than chronological age. From one year to the next, the group would change slightly as a few kids moved, went back to school, or graduated, and new members joined.
