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.

Scaffolding vs Differentiation

My recent post on scaffolds and success criteria seemed to be useful to folks, so I thought I should share something more on scaffolding that can help to further clarify the term.

Scaffolding and differentiation are both words frequently thrown around in schools, often interchangeably and without precision. But there’s a clear distinction between the two that must be made, most especially as teachers are increasingly pressured to “differentiate” their lessons by school and district leadership with little guidance and concrete models.

So what is differentiation?

Differentiation asks teachers to plan different tasks or learning experiences for different groups of students, with the idea being that we can better meet the needs of diverse learners.

So for example, if we had our “high” student, our “medium” student, and our “low” performing student, we might provide a different text for each one in order to ensure they would be reading something at their “level.”

But there’s a problem with this. If the so-called “low” students only ever receive less complex and challenging expectations, texts, and learning experiences, they will continue to perform at a lower level.

This is why too many of our kids end up in “remedial” classes if and when they make it to college. This is why too many students consigned to a segregated “self-contained” program rarely even make it to graduation.

There’s another problem with differentiation. It demands quite a bit from a teacher to design (at least) 3 separate tasks or resources for any given lesson — time and energy that could perhaps be more effectively spent elsewhere.

To acknowledge these problems is not to say that differentiation can’t be applied effectively nor that it is universally the wrong thing to do. Structures for guided reading, for example, draw from this model and can be very effective in a school and classroom that have developed the necessary systems and routines. But these problems are big enough that they should give us strong pause before mindlessly evaluating and chiding teachers about whether they are adequately “differentiating” their lessons.

What is scaffolding, and how is it different?

The concept of scaffolding shifts how we approach meeting the needs of diverse learners.

We may have students coming into a learning experience with differing levels of knowledge, ability, or background, but rather than providing them with something different, we instead consider how we can provide the scaffolding necessary to ensure they can work together in grappling with a common task or text.

This is a shift offered by common standards, which demand a shared set of expectations for all students. For our students who may struggle in meeting these more rigorous demands, we must consider how to scaffold the concepts, procedures, and environment to support their engagement in practice with the texts and learning experiences that can enable them to meet those expectations.

This is certainly not an easy thing to do, either. But if I had to take a pick about what is going to give me the most bang for my buck, designing access and practice with common vocabulary, tasks, and texts is where I would ask educators to more wisely invest their time and energy.

For more on what that scaffolding should look like, take a look at my prior post, Scaffolding and Success Criteria.

Student Grouping: What is Effective?

How do we leverage student grouping to best promote achievement?

This is a question teachers and administrators ask themselves almost daily. Unfortunately, there are few clear or easy answers. But we can draw out a few general principles from recent research and other sources of knowledge that may help to inform our instructional practice.

It’s important to acknowledge there’s often a steady pressure on teachers to utilize group work. And for some teachers, grouping students by ability can make serving a wide disparity of different levels of students more manageable.

But there’s an often unstated assumption: group work is inherently superior to whole class or independent learning. But is group work always better than other modes of learning?

Tom Bennett, a British behavioral specialist, argues in an article in American Educator, “Group Work for the Good,” that there is little research to suggest group work is better for academic learning. Bennett cautions teachers to only “use group work when you feel it is appropriate to the task you want your students to achieve, and at no other time.

OK, but what are the times when group work is appropriate? Douglas Fisher and Nancy Frey, in their book, Guided Instruction: How to Develop Confident and Successful Learners, offer some important insight. Here’s a short passage from their first chapter:

“. . . an understanding of memory systems has profound implications for instruction, which include creating systematic and intentional scaffolds of students’ understanding rather than leaving them alone to discover information independently. That’s not to say that students should not work together in collaborative learning; they should. We have argued for productive group work in which students interact with one another and generate ideas to produce individual works (Frey et al., 2009). But this work must center on the consolidation and application of content that students already know. It’s neither the time nor the place to introduce new information. Doing so would overload the working memory system and fail to ensure learning(Bold added).

In other words, new 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.

So now we’re only selectively and strategically using group work to reinforce content we’ve already introduced to our students. But how do we ensure students are productive during the times when they do work as a group? Here it can be instructive to look at some of the analysis coming out of the business sector. Fostering productive teams, after all, is critical to the success or failure of many modern businesses.

One finding from the business realm that will make immediate sense to educators is that creating a context that fosters shared identity promotes productivity. You can read more about this research in “Spaces the Signal Identity Improve Workplace Productivity,” in the Journal of Personnel Psychology. We know that giving our students a sense of belonging and recognizing who they are and what they bring is critical to fostering a positive school community. But it’s good to know that it also can improve group performance.

Another finding is that how a team communicates is what determines its effectiveness. As presented in an article, “The New Science of Building Great Teams” in Harvard Business Review, effective teams communicate more equitably and with higher engagement. And even more critically for consideration in a school context, socialization outside of formal meeting time has a huge influence on team effectiveness. What this means for educators is that fostering effective group work requires time and training. Furthermore, as described in a passage “Group Dynamics for Teams” by Daniel Levi, this training requires norming, socialization, and building cooperative skills. Educators know that many of our students struggle with social skills and working productively together. These skills must be taught and developed.

Similarly, moving into research from higher education, in “What makes a ‘good group’? Exploring the characteristics and performance of undergraduate student groups” the authors argue that if “team working skills” are “important as a learning outcome, they must be assessed directly alongside the task output.” In other words, if a teacher is going to utilize group work for a task, they must establish explicit learning objectives for the skills practiced in the group work itself, not only for the content of the task. This again reinforces the idea that when we do use group work, we must do so strategically.

This builds off of Robert Slavin’s review of educational research, as outlined in an ACSD article, “Cooperative Learning and Student Achievement,” which suggests that not only must effective group work have group goals and rewards, but also must hold each individual accountable for their contribution. Group work which incorporates only one aspect of those two critical components (group goals and individual accountability) demonstrates little benefit to learning, whereas group learning which incorporates both is far more effective.

Even adult research teams require training and practice to develop intrapersonal awareness, foster shared norms, and to understand that conflict is normal, as suggested by a paper “Creating and maintaining high-performing collaborative research teams: the importance of diversity and interpersonal skills.” The authors further suggest that fostering diverse teams is essential to productivity.

This latter insight, that diverse teams are more productive, may be one of the most useful within a classroom context. Various studies, as presented in an article on Harvard Business Review, “Why Diverse Teams Are Smarter” by David Rock and Heidi Grant, suggest that ethnic and racial diversity makes for more effective, deliberative, and innovative teams. This is an important consideration for teachers when forming groups.

However, it’s important to note that research on homogeneous vs. heterogeneous grouping is mostly unclear. Ultimately, how a teacher chooses to group students must be strategic and based on the task and learning outcomes. But the findings on diversity seem to suggest that our default should be mixing students of different backgrounds and ability.

A synthesis of findings on effective group work

Ok, so we’ve reviewed a fair amount of information on grouping. Let’s summarize what we have so far:

  • Use group work only when it is necessary to achieve the task you are planning
  • Use group work only to reinforce and apply content students are already familiar with
  • Create a classroom and school environment that fosters a shared identity
  • Provide norming, time for socialization, and training in the cooperative skills students will require to work productively as a team
  • Set explicit learning targets for group work skills when engaging in a group task, while holding each individual student accountable for their work within the group
  • Group students heterogeneously to promote greater critical thinking and creativity

“When teaching the course, I always imagined that one of my students would someday be US president. I would pause before entering the lecture room and ask myself, ‘Twenty years from now, when one of these students is the most powerful person on Earth, what will I regret not having taught? How will I consider today’s lecture a failure?’ Then I would think of the day’s message and make sure it was well understood by all.”

A Writing Method That Deepens Knowledge: The Hochman Method

paper

What if there was a method that could not only explicitly teach students core writing skills, but simultaneously deepen their domain-specific knowledge?

Turns out there is: it’s called the Hochman method.

I’d heard about Judith Hochman’s writing method for some time, but only finally got the opportunity to attend a workshop last month. In case you haven’t heard about the Hochman writing method, you can read more about it’s impact in Peg Tyre’s 2012 article in the Atlantic, and get an overview of the method on it’s website.

In a nutshell, Hochman’s method is a systematic, explicit approach to equipping students with the ability to recognize and construct clear and complex sentences, only then moving on to constructing paragraphs, and from there to composition. The vast majority of teachers (such as myself) go straight to composition, then use generalized rubrics that provide little specific guidance on revising for grammar and mechanics.

Students are thus passed on from grade to grade with little instruction on constructing well-written, fluent, grammatically accurate sentences beyond vague comments such as, “Make sure to reread your sentences out loud to check for grammar.”

But there’s even a deeper potential impact of Hochman’s method: it reinforces content knowledge in tandem to building writing knowledge and ability.

In a former post on ideas from cognitive psychologist Daniel Willingham, we explored just how critical–yet how very rare–it is to have a school-wide, systematic curriculum that reinforces knowledge coherently and sequentially across classrooms.

Furthermore, we know from research that one of the most powerful levers for building and reinforcing knowledge is “low-stakes quizzing.” When used to interleave and distribute practice across time, this is a highly effective form of transferring information into long-term memory.

Like many of the findings from the realm of cognitive science, this all sounds great in isolation, but when you try to translate it to a school and a classroom, it gets significantly more sticky, especially in a subject like ELA. Many things we cover don’t fit neatly into a multiple choice quiz.

And many teachers are highly allergic to anything that smells like a standardized test. And even when they aren’t, developing a well-designed and valid multiple choice question is surprisingly intensive.

Here’s where Hochman’s method comes in. Her method provides explicit and clear sentence construction activities that can be applied to any content and that can be used to assess comprehension of texts or topics. This sentence-level work serves the same function, in other words, that low-stakes quizzing would, while also explicitly teaching writing skills.

So imagine this: a school creates an initiative, after being trained in Hochman’s methods, to embed sentence-level activities into every text that is read in social studies, science, and ELA. These activities would serve as formative assessments of content. And once those activities for each text are developed, a resource packet is made that can be used again and again in the future, whether or not a teacher leaves the building. That’s an endeavor that could not only be high impact but furthermore sustainable.

For an example of one of Hochman’s sentence-level activities (Because, But, So), check out Doug Lemov’s post, Hochman’s ‘But, Because, So’ Sentence Expansion Activity. He also highlights Hochman’s distinction between editing and revision here.
