The Open University Maths Dept University of Oxford Dept of Education Promoting Mathematical Thinking ProMath 2014 On Being Stuck Problem Solving Makes School Mathematics Enjoyable and Challenging John Mason Helsinki 2014
Outline • Forms of Being Stuck • Getting Unstuck: having-come-to-mind • Developing a Repertoire Come to mind: Tulkaa Mieleen Coming to mind: Tullen Mieleen Having come to mind: Tultua Mieleen
Conjectures and Assumptions • Everything said here is a conjecture … • to be tested in your experience! • Enjoyment (in mathematics) arises from acts … • the exercise of internalised skill • the use of natural powers • the development of those powers • What you get from this talk is most likely what you notice happening inside you as you seek for examples of your own which parallel mine in some way … • through which you can consider and interrogate my proposed distinctions and connections
Method of Enquiry • I prefer to be phenomenologically experiential • I shall offer some brief-but-(hopefully)-vivid account of incidents which may resonate your experience, making it available for inspection. • Theorising is an epiphenomenon, and will arise as and when it seems apppropriate
Incident • When my son was about 8 or 9, he asked where I was going that day, and I told him I was going to Liverpool to give a talk. He asked what it was about so I told him that it was about “What to do when you are stuck”. After a thoughtful silence he announced “Get out and push!”. • Being Stuck is an honourable state, yet we are usually in a hurry to ‘get out and push’. • ‘get out’ ––> withdraw from the action (or inaction!)‘push’––> invoke some other action
Reflection • Have you ever been stuck, but only realised it some time later? • Have you ever been stuck, with a vague sense of being stuck but without seeming to be able to do anything about it? Accounting-For Multiple selves which harness energies in characteristic ways, invoking characteristic actions, emotions and thoughts Different selves dominate at different times and under different conditions Spectrum of intensities suggests all aspects of psyche are involved: enaction, affect, cognition & will
What Keeps Me Stuck? • Immersed in action; oblivious to possibility • Awake to possibility but … • Insufficient energy available to withdraw from action • lack of desire (affect) • lack of sufficient will • lack of action • lack of insight, connection, narrative • Absence of possible action • blocked or obscured by prediliction/habit • unavailable
Incident • Linear functionals; dual of a vector space; dual of the dual … different in finite and infinite cases • Struggling over some hours to get to grips with expressions such as LV(f) = f(v) and its meaning. Perisitence; struggle over time; gradual realisation (literally) Things Take Time
Incident • I recall in my early years at the Open University being introduced to the function as an example of a function which is differentiable at 0 but which is not differentiable on any interval containing 0. Indeed it has arbitrarily large slope arbitrarily close to 0. • may be 1 in analysis, but not out on the street” Acting As If (William James) Things Take Time (Piet Hein) A solved problem is as useful to the mindas a broken sword on the battlefield (Idries Shah)
A Good Expanation Does Not Explain Everything Zen saying (Shigematsu) • In what sense is the same as ? • How do you know? Theorem-in-Action (Vergnaud) Is it sufficient to say “because they give the ame answer?”
Becoming Unstuck: Pushing & Pondering • 99 heuristics (?!?) • Learn from experience: • One thing we don’t seem to learn from experience,is that we don’t often learn from experience alone. • Develop an inner witness-monitor • Two birds, close-yoked companions, Cling to the self-same tree.Of these one eats of the sweet fruit, The other, nothing eating, looks on intent
Reflection Personal: meanings for person; emotions Russian School Intellectual: specifics of task Initiated through conflict/dissonance Maintain habits Reproductive & Productive Actions Emotions Thoughts Change of perspective Initiated through resonance? Spective In the moment In-action Paring Retro-spective On-action Post-paring Pro-spective Pre-paring imagining
Incident • Add 1234, 123.4, 12.34, 1.234, .1234 1234 123.4 12.34 1.234 .1234 6170 Where should I put the dot? When we don’t know what to do, we enact whatever action is available Bob Davis; Brown & van Lehn; …

Multiple Discourses • Piaget: Assimilation & Accommodation; Reflective Abstraction • Vygotsky: Internalising higher psychological functions through being in the presence of others • Gattegno: integration through subordination • Gattegno: Awareness • Only awareness is educable; Only behaviour is trainable; Only emotion is harnessable; Only attention is directable. • Reacting & Responding • Systems S1 and S2
Incident 6 • A baseball bat and ball cost together one dollar and 10 cents. The bat costs one dollar more than the ball. How much does the ball cost? S1 Automatic, Reactive, Mechanical, Habitual Temptation: $1.00 and $0.10 Parking Parking S2 Considered; Responsive; Cognised; Justifiable Considered: $1.05 and $0.05 Kahneman, Franklin, Leron
Incident 9 • Stuck on a problem I go down the corridor and ask a colleague if I can explain my problem. The colleague sits there, doing nothing beyond appearing to give me some attention. At the end, I thank them and return to my office with renewed vigour and a fresh view of my problem.
Incident: Stuck in a Rut • How to display a woven copy?

Where is the Pleasure? • In using your own powers • Not having them usurped by text or teacher • By meeting (appropriate challenge) • From a sense of freedom, of participating intentionally in choice of action, emotion, thought-pattern, and attention
How Can teachers Foster & Sustain Mathematical Thinking? • By using tasks in which many learners spontaneously use some power, some action which the teacher knows is a valuable contribution to learners’ repertoire • By allowing gestation time • By drawing attention to what was successful and providing a label • By Scaffolding & Fading (increasingly indirect prompts) • By promoting a re-flective & pro-flective stance • How do you know? • What actions were effective and why? • imagining oneself in the future, enacting a particular action
