On Threshold Concepts and Experiences

dscn5282

In a recent post, “On Knowledge and Curriculum,” we reviewed a few disruptive ideas from cognitive psychologist Daniel Willingham, with the most incendiary implication being:

a school needs to come to a consensus on the topics, texts, vocabulary, and concepts that are most essential to know within and across each academic domain and carefully sequence and reinforce those concepts across classrooms and grades.

So how can a school embark upon this quest? In this post, I will attempt to provide some guiding ideas and protocols for this work.

How Do We Reinforce Knowledge?

First off, a few guiding documents to equip you with the cognitive principles of affirmative testing, which are essential to reinforcing knowledge over time:

—Annie Murphy Paul, “Affirmative Testing” (she has designed an entire e-course around these concepts!)

—Deans for Impact, “The Science of Learning

How Do We Determine the Knowledge that is ESSENTIAL?

Folks are going to disagree about this, including the “experts,” so ultimately, this determination should be made collaboratively within a school (and beyond). The key is that the school comes to a consensus on this essential knowledge, then teachers carefully sequence it across the curriculum and quiz it repeatedly in a low stakes manner.

There’s a useful frame, known as threshold concepts, for drilling down to this “essential knowledge” within a specific academic domain. Threshold concepts come out of higher ed academia, and it’s admittedly a bit esoteric in the literature, but I think it’s a useful lens with practical implications. Threshold concepts are very much related to Wiggins and McTighe’s “big ideas,” but with a few interesting twists.

I first stumbled over the threshold of these concepts in blogs from UK educators, to whom I’m indebted for starting me on this journey:

—Alex Quigley, “Designing a New Curriculum: What are your ‘Big Ideas?’

—Joe Kirby, “One scientific insight for curriculum design” (he also sums up research on affirmative testing really well here)

What we’re really trying to get here is that 20% of the knowledge that is most essential to understanding an academic domain in a specific grade. Here’s a frame for this:

How can threshold concepts help us to determine that 20% of essential knowledge within a specific academic domain? I decided to review some of the literature for further clues:

—Ray Land, Jan Meyer, and Jan Smith,”Threshold Concepts within the Disciplines” (Land and Meyer are the rockstars who originated the concept)

selection_012

—James Rhem, “Before and after students “get it”: threshold concepts” (a useful overview)

This idea of a transformation of understanding that is essential for progressing deeper into the academic content is really interesting.

selection_013

—James Atherton, “How do people ‘get it’?” (another useful overview)

There are many other characteristics that were identified, but they don’t all seem very useful in a practical sense for K-12. I think the three outlined above are the most relevant and applicable.

—Tracy Fortune, Priscilla Ennals, and Mary Kennedy-Jones, “The Hero’s Journey: Uncovering Threshold Barriers, Dispositions, and Practices Among Occupational Therapy Students

selection_014

I love this idea of viewing a student’s passage through a threshold concept as akin to a hero’s journey. In considering this journey, what are the troublesome obstacles and bottlenecks that student will face? The idea of “bottlenecks” comes thanks for the link immediately below. In thinking through this, I also think we need to acknowledge that bottlenecks may not be purely conceptual — they can also be procedural, in the form of skills required to complete academic tasks, as well as social-emotional (this can be a tremendous and often unaddressed barrier for many kids).

In this sense, then, we can expand the notion of crossing a threshold to not solely refer to concepts, but furthermore experiences. As educators, we seek to design experiences in which students engage in an academic form of a hero’s journey, learning to overcome barriers and gain the intellectual accomplishment of mastering skills and knowledge.

—Joan Middendorf & David Pace, “Decoding the Disciplines: A Model for Helping Students Learn Disciplinary Ways of Thinking” (they offer a useful protocol that I’ve drawn from below)

OK, So How Do We Discover These Threshold Concepts and Experiences?

But we still need some kind of process for distilling away all the cruft and getting down that 20% of the most essential knowledge within a content and grade.

Here in the US, we have a general list of skills we use as guidance in the form of state standards. And as I’ve done with the Common Core standards, we can do a deeper analysis to begin unpacking what that knowledge might be.

But this can still be at a pretty abstract level, and we want this to be relevant to classroom teaching. By focusing on the topics and texts that will be studied, we can make this more concrete.

Because English Language Arts is my specific area of expertise, I’ve focused my efforts in this area, especially since this content area is probably the most difficult to pin down in terms of a progression of knowledge.

There’s two ways we could utilize this protocol: 1) unit of study, or 2) over the entire school year.

1) Consider the topics and/or texts that will be taught.

2) What will be the product or products that students will be expected to create that can demonstrate their mastery of learning? (This product could also be a performance).

3) What are the primary modalities that this product is focused upon? In literacy, of course we’re focused on all modalities, but it helps for a department to focus upon the one they consider most essential.

4) Now consider the standards that your district adheres to. For the Common Core, they are helpfully broken up by modality, so turn to that modality. Then, narrow down which specific, few standards you will primarily be targeting.

5) What are the bottlenecks, most especially those that are conceptual and specific to this content, that students will encounter?

6) Evaluate the list of items you have generated. Do they fit the criteria of a threshold concept or experience? Are they transformative, integrative, and troublesome? If not, they may not be essential.

7) You don’t have to do this, but I find that at this step it can be useful to phrase the threshold concept in the form of a message or lesson, akin to a theme statement.

For example, for an upcoming professional learning session I’m working on about supporting struggling middle school readers, I’ve identified the following threshold concepts:

  • Students that struggle with reading comprehension also often struggle with a lack of academic and world knowledge. An English Language Learner can also be understood as native English speakers that do not understand the language of math, science, social studies – i.e. academic, formal, domain specific language.
  • A teacher must work through a task/text in order to identify key takeaways, key vocabulary, and potential barriers to learning, regardless of whether a curriculum is provided.
  • All learners can be engaged in reading and comprehending complex academic texts through well-designed activities, tasks, and resources.
  • An environment in which a student feels safe to take risks in front of peers is a prerequisite for learning — most especially for struggling readers.
  • Learners should be explicitly equipped with strategies and mindsets for when they encounter challenging vocabulary on their own.

It’s important to note that threshold concepts will vary completely depending on any teacher’s specific set of knowledge, perspectives, and interest, and I think that’s OK. What’s most important is that once these most essential concepts and experiences have been identified and voiced, they will not only help to focus that teacher’s instruction on what they feel is most important, they will serve as a basis for arriving at a consensus as a department and as a school.

Here’s a few really basic examples at a unit level of study:

Now that threshold concepts and experiences have been identified, here’s the really hard part:

This is where the rubber hits the road. This is the part that is so very contrary and disruptive to the norms of public education.

On Knowledge and Curriculum

500px-power_of_knowledge-svg

Forget the presidential debates, this is more important.

I attended a PD today that featured cognitive psychologist Daniel Willingham. It’s pretty rare that my employer, the NYCDOE, offers professional learning that has someone presenting from the academic research realm, so when I saw this was happening, I jumped on it.

I’ve been following Willingham’s articles in American Educator and have read Why Kids Don’t Like School, and I’ve been convinced of the importance of a strong curriculum and building knowledge for a while now, but it was nice to get a direct and clear reminder of what really matters in literacy, especially when that message is so very rare.

There were a lot of great ideas and takeaways on motivating children to read at home and on reading comprehension in general, but there were two main points that especially struck me during his presentation (the summary and phrasing is my own):

  1. Knowledge needs to be “in the mind” in order for reading comprehension to be effortless, rather than a problem-solving struggle to determine meaning.
  2. We can only build the broad, world knowledge required for literacy through a carefully sequenced and structured curriculum.

If you take these points to be accurate, then the implications are quite revolutionary in comparison to the regular practices of most schools and districts.

Let’s break down why this runs so counter to the norm.

Here’s what would need to happen:

  • If knowledge must be “in the mind” (rather than on Google) than that means the knowledge considered worth studying must be reinforced and revisited, tested, interleaved, sequenced, and spaced throughout a school’s curriculum.
  • That means across classrooms and across grades.
  • Therefore, a school needs to have come to a consensus on the topics, texts, vocabulary, and concepts that are most essential to know within and across each academic domain.
  • That means that each teacher (or at the very least, a department head or team) will have to have invested a substantial amount of time, both individually and collaboratively, into studying those texts and topics themselves in order to know how to design a learning environment, projects, activities, field trips, and interim assessments that will provide the access to and reinforce that knowledge for all students.
  • This would of course be accompanied by adjusting the curriculum periodically based on an analysis and reflection on interim assessment data and student work.

Sound pretty straightforward? No. Here’s the norm in most schools:

  • What most prioritizes a school’s focus are external assessments, such as state tests. ELA tests in this vein consist of random passages of text that are meant to focus on isolated reading skills devoid of knowledge. Therefore, what is taught and focused upon are the practice of skills devoid of knowledge.
  • That’s what constitutes an ELA curriculum for many schools.
  • A teacher is either not provided a curriculum, or is provided a curriculum but no support, or is provided a curriculum and support but the curriculum is not oriented around sequentially building knowledge.
  • Even when a curriculum might be provided and might be relatively well-crafted (this is a rarity, and if you know of such a curriculum, tell me. I can name two. Maybe three), I have yet to have seen any curriculum that still does not require a teacher to revise and adjust it substantially based on the needs of their students, the circumstances of their school or classroom, or their own particular style and knowledge.
  • Thus, in those rare schools where there is even a coherent curriculum “in place,” the point made above about investment of time still holds. A substantial amount of time needs to be spent in designing and continually molding the school around and in support of that knowledge embedded within the curriculum.
  • Most of what is taught in different classrooms in a school has little coherency across a school.
  • What is a taught in any given classroom is rarely reinforced via low stakes quizzing across an entire school year.

See the problem? From what I’ve seen in much of the professional development sessions and focus of schools and districts is a focus on individual teacher strategies and practices. But let’s get real. If a school does not come together to determine and design it’s mission around the knowledge and skills it will teach sequentially and systematically, then there will be little impact.

How My School is Designing Stealthy Interventions

I’ve written about the idea for “stealthy” interventions that I was introduced to at the ResearchED conference by Carl Hendrick. I recently was able to present some of that research, along with other ideas about growth mindset and WOOP goal-setting, to my staff last week. I’m sharing the presentation I used in the hopes that it might give you ideas for your school! Share and share-alike.

How a Lack of Natural Resources Can Affect a Child’s Education

By Matthew Hoelscher (Flickr) [CC-BY-SA-2.0 (http://creativecommons.org/licenses/by-sa/2.0)%5D, via Wikimedia Commons
An interesting article in the New Yorker, “Spare the Rod, School the Child” by Michelle Nijhuis, gives us urgent lessons with implications not only to our swiftly changing ecological environments, but also may bear lessons for our educational environments as well.

Possible lessons we can derive from the article:

In Ghana, it was discovered that a decline in fish populations could be directly correlated to a rise in children kept at home from school. Why? Because baboons were causing so much damage that “many Ghanaians were keeping their young children out of school to help guard family farms.”  Why were baboons destroying farms? Because their populations had grown since their competitors were becoming bushmeat. Why were people increasingly eating bushmeat? Because fish populations were declining.

The native Ghanians knew that fish were the cause of this. The researcher who ended up verifying their knowledge with his research at first dismissed their perceptions. “I thought, ‘Oh, that’s interesting, but these uninformed people aren’t aware of some bigger dynamic.’”

In the world of education, it’s very easy to get caught up in big idea debates at the level of policy, politics, and research. An important lesson from this article is the reminder that we always need to find a way to ground and center our discussions around those whose lives are impacted the most. In the case of education: students and their parents. How can we do that? By asking them!

As Melinda D. Anderson so very neatly put it on Twitter:

Scarcity of fish can be traced to other causes of social ills across the globe: “indentured servitude and child slavery” and “fishing militias” in Thailand, HIV positive women in Kenya exchanging sex for fish, and in West Africa, “child labor and child slavery are increasing.”

Yet “these linkages are rarely discussed in academic circles, or even in the popular press. ” Why is that?

“The science side is very focused on natural-resource trends and not really thinking about social consequences, while the policy side is looking at Somali pirates or elephant ivory, and totally disconnected from the root causes.

Again, there are obvious parallels to the world of education policy and research here. As biologist Justin Brashares puts it in the article, “Our whole research and policy response system is really poorly equipped for the future.”

Why are our institutions of education failing? Ask the students. Ask their parents. Take a walk in their communities. It might be something as starkly simple as a scarcity of a natural resource.
