From surface to deep learning: The importance of knowledge

This article illustrates how the use of the SOLO Taxonomy allowed our students to progress from shallow to deep thinking.

Of the five essential elements in the PYP, is there one that often gets overlooked when planning units of inquiry?

The planner prompts us to think explicitly about attitudes, skills, action and concepts. But what about knowledge? It can sometimes be challenging for teachers to identify a body of knowledge for a particular unit; it can feel uncomfortable identifying specific knowledge to be learned because it can direct the inquiry in a way that takes control away from students. I would argue, however, that identifying some essential knowledge needed to understand a central idea gives more power to the students and encourages them to become self-directed, assessment capable learners.

In Making the PYP happen (2009), the section on whether it is possible to “identify a particular body of knowledge for PYP schools” is addressed by explaining that, although there are some “core commonalities” that represent shared human experiences (which led to the selection of the six transdisciplinary themes in the PYP framework), schools should develop their scope and sequences to reflect their unique circumstances. But do our scope and sequence documents always document the knowledge associated with units of inquiry?

Lynn Erickson’s Structure of Knowledge (2002) is often used in the PYP workshops to illustrate how concepts and knowledge interact to help students form a principal generalization (similar to the central ideas we all have in our programmes of inquiry). The foundations of being able to form these principal generalizations (or understand a PYP central idea) are based on identifying the essential facts that will interact with the chosen macro and micro concepts (or, as we call them in the PYP, key and related concepts).

John Hattie and Gregory Donoghue (2013) define learning as:

The process of [students] developing sufficient surface knowledge to then [enable them to] move to deeper understanding such that one can appropriately transfer this learning to new tasks and situations.

Hattie states that there is a right time for interventions and the use of deliberate learning strategies. Based on his 800+ meta-analyses of now over 50,000 research articles, Hattie has argued that allowing students to inquire without structure too early does not work, having an effect size of only 0.31, less than an acceptable year’s growth (the 0.4 ‘hinge point’ which defines a typical year’s growth).

This is where the SOLO Taxonomy can come in handy. Although it was developed by Biggs and Collis back in 1982 it seems to have had a resurgence of interest recently. Hattie (2012) describes it as “the most powerful model for understanding these three levels of understanding [surface, deep and conceptual]”.  In her new book entitled The Power of Inquiry (2015), Kath Murdoch writes that the SOLO Taxonomy “explicates the work of John Dewey, who wrote extensively about our understanding arising from our capacity to see connections”. And Pam Hook (2012), who has released a variety of publications to help schools implement the model across a whole range of subject areas, states that it offers solutions to “ensure cognitive stretch for all students, build interest for all students, build confidence for all students and share power amongst all students.”

In the SOLO model, there are four levels of thinking. At Seisen International School we have simplified the names of these levels for use with our students: unistructural (which we have renamed ‘one idea’), multistructural (which we have renamed ‘many ideas’), relational (which we have renamed ‘connecting ideas’) and extended abstract (which we have renamed ‘going further’). The first two levels are surface level learning and require students to find information and collect ideas. The last two require deeper thinking where students have to process the information they gathered in the first two levels. If students are not at a stage where they have an idea about the concept, topic or subject, they are said to be at the pre-structural stage (which we renamed ‘getting started’).

At Seisen we have had some success adopting the SOLO Taxonomy.  Students refer to the levels when reflecting on their progress and setting goals. It has become our language of learning, having aligned it with our own inquiry cycle (Getting Started – Investigating – Connecting Ideas – Going Further). Using a list of appropriate verbs at each level, learning engagements are designed across the continuum so that students can identify where they are and select their next steps. The students become evaluators of their own learning and teaching teams have a tool to use to answer the question posed in box 3 – What are the possible ways of assessing student learning in the context of the lines of inquiry? What evidence will we look for?

By the time the students approach their exhibition year, consistent use of the tool is enabling students to plot their own learning progressions using the SOLO verbs at each stage of their independent inquiry. Isn’t this our goal as teachers to structure inquiries in a way that encourages students to become independent, self-directed, assessment capable learners?
