A Revision on Group Work: Assign complex—rather than simple—tasks

pexels-photo-705674.jpeg

Paul Kirschner, John Sweller, Femke Kirschner, and Jimmy Zambrano published a recent paper in the International Journal of Computer-Supported Collaborative Learning titled, “From Cognitive Load Theory to Collaborative Cognitive Load Theory,” in which they make the case that cognitive load theory needs to be reconsidered from a different frame for group tasks.

I found it interesting because I had created a synthesis on group learning a while back (read all about it here), and much of Kirschner et al.’s synthesis aligns with much of what I found, such as that group work requires the development of collaborative skills, the importance of clear, accountable roles and expectations for group tasks, or that heterogenous grouping should be our default when creating groups.

However, there was one key piece that seemed to contradict a finding I had drawn from Doug Fisher and Nancy Frey’s book, “Guided Instruction,” which is that new concepts and information should not be introduced during group work, as this would overload students’ working memory.

Kirschner et al. instead suggest that working as a group creates a collective working memory, and that therefore group tasks should be more complex. They state, “… learning in a team is more effective than individual learning if the complexity of the to-be-learned material is so high that it exceeds the limits of each individual learner’s working memory.” They furthermore suggest that greater complexity will make the task more engaging for the group: “Collaboration will occur when the task is complex enough to justify the extra time and effort involved in collaborating with others.”

However, they also caution that “In terms of cognitive load, if learners have not acquired [task-specific collaboration] skills prior to beginning on the collaborative task, the load induced here could be so high as to hinder collaborative learning.” This agrees with what I also found in my synthesis, which is that fostering effective group work requires time and training, with explicit learning objectives for the skills practiced in group specific tasks. As Kirschner et al. puts it, “We may need to be taught how to communicate and coordinate carrying out complex tasks in order to optimize transactive activities and construct better knowledge and skill schemas (Zambrano et al. 2018).”

Kirschner et al. also highlight the different considerations we need to make for students based on what they already know. In fact, they seem to suggest that students with low levels of domain-specific knowledge can benefit the most from engaging in group tasks, whereas students with higher level of expertise may have their learning hindered by the additional elements introduced by collaboration. Here’s two relevant quotes on this:

“When teams are composed of learners with a low level of domain-specific knowledge, these novices need to be involved in cognitively demanding search-based problem solving, whereas when they are knowledgeable, this is not the case as the learners can probably deal with the problems using their available knowledge base. Also, when teams are composed of learners with a low level of domain-specific knowledge, there is a greater potential for a larger increase in collective WM than when individuals have high levels of domain-specific knowledge required by the task.”

“With respect to cognitive load, if learners have relevant knowledge to carry out a task, communication and coordination activities may be unnecessary or even detrimental to learning. When there is little domain-specific knowledge, the cognitive load incurred by transactions could positively impact learning but where there is a great degree of expertise, and thus where transactions are either unnecessary for or detrimental to learning (Zambrano et al. 2017b), the cognitive load incurred could negatively impact learning.”

I’m glad I reviewed this article, as it has helped me to clarify my thinking about assigning group work.

To summarize the key point I’m revising my thinking about group work on:

Fromnew concepts and information should not be introduced during group work. Group work should be used for reinforcing, consolidating, and applying information students have already been exposed to

to

When assigning group work, ensure that the task is complex enough to warrant collaborative effort.

I’ll provide an updated decision-tree and guiding document to reflect this learning soon.

Hysteresis and the Legacy of Industrialization

IMG_20151231_160803.jpg

I recently shared a fascinating study on the impact of the historical legacy of a place, which found that students living in neighborhoods with a legacy of economic and residential segregation had greater odds of dropping out of high school compared to their peers in other neighborhoods.

The existing social capital of a neighborhood, in other words, is associated with the historical legacy of that particular place.

This makes a lot of sense to those of us that work in communities with legacies of poverty and trauma. And it also relates to a concept that Will shared here back in 2012: hysteresis. As explained on Wikipedia, hysteresis refers to “the dependence of the state of a system on its history.” This concept can be applicable to a wide range of systems—in our case here, we are considering socio-ecological systems.

Another recent study presents further support for the impact of the legacy of a place on people. Researchers used online surveys of the “big five” personality traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism) and examined them in connection to a region’s historical legacy associated with industrialization during the 19th and 20th century.

Their results suggest “that the massive industrialization of the 19th and 20th centuries had long-term psychosocial effects that continue to shape the well-being, health, and behaviors of millions of people in these regions today.”

“. . . .Our research shows that a region’s historical industries leave a lasting imprint on the local psychology, which remains even when those industries are no longer dominant or have almost completely disappeared.”

The author concludes that “Without a strong orchestrated effort to improve economic circumstances and people’s well-being and health in these regions, this legacy is likely to persist.”

Granted that this study is based on data gathered from online surveys. But the “big five” survey has a fairly robust research base behind it and predicts academic achievement and parenting behavior (you can also take the survey yourself; I found my own results enlightening). But of course, further research into the impacts of the historical legacy of a place should continue to be pursued.

In the meantime, for those of us who work with children raised in communities that bear the legacies of injury, we need to be mindful not only of the individual needs of the children before us, but furthermore the history of the place within which they live.

Why do we ignore environmental design interventions in education?

IMG_20180217_060340.jpg

“Initially, medical audiences I spoke to in the 1980s listened politely, though probably some were dubious and did not really accept the findings [that views of nature improved patient outcomes]. But today, after so much progress in mind-body medical research, few would seriously question the notion that if an environmental design intervention is shown to reduce patient stress, then it could also foster better clinical outcomes. The idea that stress-reducing interventions improve clinical outcomes has become mainstream knowledge that medical students learn.”

—Researcher Roger Ulrich, in a 2010 interview by Healthcare Magazine

And yet, for those of us who work in public education, this understanding is not so widely embraced even still in 2018. Despite the clarity of research in our field around the impact of toxic stress on children’s learning, we pretend that the design of the physical environment of our classrooms and schools has little bearing.

We may be ignoring what may be one of the most direct and sustainable methods to improving outcomes for kids — designing our schools to foster and promote health and well-being.

The Symbiosis Between Scaffolding and Differentiation

A while back I wrote a long post redefining scaffolds and examining their connection to success criteria.

I then wrote a post drawing a distinction between scaffolds and differentiation, and I cast some shade on differentiation.

But I’m no longer quite as opposed to differentiation, and I can now see how there can be a strong symbiosis between scaffolding and differentiation.

I’ve been working with a school in the Bronx where we’ve been talking a lot about these concepts, and they’ve helped me to think a little more deeply. So I figured it would be worth sharing my updated learning.

Why it’s important

Teachers are often criticized by school and district leaders for not “differentiating” enough, yet rarely provided any clear guidance on how to do so. And there’s furthermore a lot of vagueness out there in the field on the distinctions between scaffolding and differentiation.

I want to share my revised thinking on the connection between the two concepts in the hope that I can help to clarify, rather than muddy, the use of these terms.

Here’s a visual model of how I now view scaffolds and differentiation:

Scaffolding = Steps

As students practice a skill or develop knowledge of a concept, their ability and understanding increases in complexity. A master teacher breaks down a skill or concept into smaller components, all the way down to the most basic and fundamental level, so that students can accelerate up the ladder towards mastery (just as jump school recruits do with a parachute landing fall).

Those sequential steps are the scaffolds.

Scaffolding, therefore, requires a teacher to be deeply knowledgeable of what is taught (content/skills).

Differentiation = Where each student is on those steps and what they need to progress

Differentiation, on the other hand, requires a teacher to know their individual students well enough to know what each student requires at every step on their trajectory towards mastery, and where they are on that trajectory.

Differentiation requires a teacher to be deeply aware of each of their individual student’s needs and current level of performance.

Distinguishing between Scaffolds and Differentiation

  • Scaffolding is aligned to a concept or skill.
  • Differentiation is aligned to the individual student.
  • Scaffolds are the sequential steps that lead to mastery of a skill or a deeper understanding of a concept.
  • Differentiation is in what manner and how much time a student may need to practice or review a step, as well as how much feedback may need to be provided.
  • Scaffolding requires a teacher to be deeply knowledgeable of what is taught.
  • Differentiation requires a teacher to be deeply aware of each individual student’s needs and current level of performance.

The two thus work in tandem.

A sidenote on how all this relates to personalized learning

This brings out something interesting about the edtech industry’s drive for “personalized learning.” The concept of personalized learning arguably aligns most strongly with differentiation.

What is not frequently discussed is that in order to personalize something, you must first define that “something” and break it into its component parts. How you do this and the decisions you make and the feedback you provide are just as important as matching that content to a student’s needs.

In other words, whenever you hear about personalized learning, ignore the inspirational student-centered rhetoric and home in on the content itself. What platform or curriculum is being used? What trajectory is presented by that content? Does this trajectory align with widely respected standards or guidance from national or international professional organizations.

Definitions and Characteristics

Scaffolding

Definition

A scaffold provides opportunities for performance and practice of the component content and skills that a student requires to achieve success in a unit of study.

Characteristics

  • Smaller, sequential components of a complex concept, task, or skill
  • Requires a teacher to be deeply knowledgeable of what is taught
  • At the right level of “desirable difficulty” for practice; in other words, a scaffold isn’t about making something “easier” for students
  • Must be mastered at each step along the way. Students shouldn’t move along or have a scaffold removed until they have demonstrated mastery of each component
  • Doubles as performance-based formative assessment

Differentiation

Definition

Differentiation provides an individual student with the targeted practice or thinking, and with the necessary feedback, in order to progress towards defined learning goals.

Characteristics

  • Adjustments in environment, content, process, or product to account for an individual student’s current level of knowledge, ability, or interest
  • Based on the trajectory of scaffolding for the current topic or unit of study
  • Requires the teacher to be deeply aware of an individual student’s needs and current level of performance
  • At the right level of “desirable difficulty” for practice; in other words, differentiation isn’t about making something “easier” for the student

You’ll notice that there is a key characteristic that is shared between these two: neither are about making something easier for a student — they are both about moving learners closer to mastery of whatever it is that they are practicing and studying.

This is important because unfortunately there is a strong tendency by educators to deem some students as incapable of achieving mastery of success in academic learning.

But what is most often the case is that the educator doesn’t know what they are teaching well enough in order to provide specific and targeted supports for their students.

There’s still a lot more to dig into on this topic — specifically how it relates to formal education plans (IEPs) for students with disabilities. But I think this is more than enough for one post!

Please push back on any of this to help me further clarify and refine my thinking on scaffolding and differentiation.

What is on your classroom walls? Why?

DSCN4327

A few weeks ago, a middle school in the Bronx that I work with had a visit from their superintendent. She blasted them for their disorganized learning environments, and for good reason: classrooms were cluttered with charts serving little purpose aside from demonstrating the residue of what was once taught.

I also happened to speak recently with a pre-K teacher of children with autism who emphasized the importance of a calm, uncluttered environment for her students. She kept her walls mostly bare. She said that the idea that classroom walls need to have something on them is “old-fashioned thinking”; such educators think that “if I have a lot on the walls, then kids are learning a lot. But it’s more about the teacher than the kids.”

This teacher thinks deeply about what her students need, and she has realized that having very little up on the walls is critical to creating an environment for learning for students sensitive to visual stimulus.

I think at some level most teachers recognize this, when they are asked. At that middle school I mentioned, the leadership and then staff discussed what an effective classroom environment looked like, and the importance of a lack of clutter was raised.

Yet in all too many classrooms, especially in struggling schools, walls are strewn with the bricolage of lessons past. How many of those charts are actively referred to by students?

A small study in 2014 by Carnegie Mellon, as reported by NBC News, backs up the idea that clutter on classroom walls can have a detrimental effect on learning. They found that:

In the sparse classroom, the kindergartners got distracted by other students or even themselves. But in the decorated one, children were more likely to be distracted by the visual environment and spent far more time “off task.”

In other words, young children are easily distractable. So putting a bunch of stuff up on the walls will distract them even more. In heavens name, why would we deliberately make it harder for our kids to focus and learn?

And yet in too many classrooms and schools, we do exactly that. We create environments that make it harder for students to focus, rather than easier.

And why do we do that? Because all too often, we put things up for other adults, rather than for our students.

Look at all we are learning!, our classroom walls scream.

The irony: all those artifacts make it harder for students to learn.

Teachers, take an honest look at your classroom walls, and ask yourself: What is on my classroom walls? Why? Who is it for? How often (if at all) do my students refer to what’s there?

Here’s a rule of thumb to combat distraction: If what is up on your wall will not be referred to by your students in the next week or two, then take it down.

Take a picture of it if you want a record of it, or do like one great teacher I worked with did and tape it to a wire hanger and hang it in a closet or on a clothes rack for past anchor charts that you can bring back out as needed.
