Effects of Social Metacognition on Micro-Creativity: Statistical Discourse Analyses of Group Problem Solving Ming Ming Chiu State University of New York – Buffalo [email protected] I appreciate the research assistance of Choi Yik Ting and Kuo Sze Wing Solving problems & Micro-creativity Under the Universal Texting plan, each text message costs $.10. Budget Texting costs $.01 per text message, but charges a monthly fee, $18. 1) How many text messages do you send each month? 2) Which company costs less for you? 3) How many texts should you send for the Universal plan and the Budget plan to cost the same? Solving problems & Micro-creativity • Difficult problem for students learning algebra • To solve this problem, novice students create new ideas and check/justify their utility (micro-creativity processes). • More micro-creativity processes Solve problem • What group processes micro-creativity processes? Micro-Creativity Processes • Creativity processes – Generate ideas – Identify/Justify utility ( Sternberg & Lubart, 1999 ) • Big “C” creativity affects society • Small “c” creativity affects person ( Gruber & Wallace, 1999 ) • Micro-c creativity processes occur at a moment in time ( Chiu, 2008 ) What Affects Micro-creativity? • Social Metacognition? • Face / Rudeness? Social Metacognition Metacognition Monitoring and control of one’s knowledge and actions ( Flavell, 1971; Hacker, 1998 ) Social Metacognition Group members’ monitoring and control of one another’s knowledge and actions ( Chiu, in press) Most individuals have poor metacognition. ( Hacker & Bol, 2004 ) Social Metacognition Questions indicate knowledge gaps Identifies gap in someone’s understanding Motivates and points out a way to fill the gap to create a new idea (+) Use old or new info to explain/justify (+) (Coleman, 1998; Webb, Troper & Fall, 1995; DeLisi & Goldbeck, 1999 ) Disagree Identify obstacles Overcome via new ideas and/or justifications (+) (Doise, Mugny & Perret-Clermont, 1975; Piaget, 1985) Face / Rude • Disagree Rudely • Excessive Agreement • Command ! Face / Rude Face = Public Self-image Disagree rudely (attack face) vs. Disagree politely (save face) ( Brown & Levinson, 1987 ) “Ten times two hundred.” Disagree Rudely “No, you’re wrong, it’s one tenth times two hundred.” Previous speaker more likely to retaliate Emotional argument Reduce new ideas & justifications () End cooperation ( Chiu & Khoo, 2003; Gottman & Krokoff, 1989 ) Face / Rude Disagree politely “if we want it in dollars, we can multiply two hundred by one tenth.” • “if” – Hypothetical distances error away • No “you” – No direct blame • “we” – Shared positioning & common cause Save previous speaker’s face Listen & understand obstacle Overcome via new ideas & justifications (+) ( Chiu & Khoo, 2003 ) Face / Rude Agree too much Concern for social relationship Reluctant to disagree with wrong ideas Fewer new ideas & justifications (–) ( Person, Kreuz, Zwaan, & Graesser, 1995; Tann, 1979; Tudge,1989 ) Face / Rude Command ! Demand implementation of an old idea Suggest that speaker has higher status than audience Ruder than question Threaten face Distract from problem solving Fewer new ideas & justifications (–) (Brown & Levinson, 1987; Chiu,2008 ) Social Metacognition Ask Questions (+) Disagree (+) Micro-creativity processes New ideas Face / Rudeness Politely Disagree (+) Rudely Disagree (–) Excessively Agree (–) Command (–) Control variables Math grade Peer Friendship Gender, ethnicity, … Group mean grade, Group gender variance … Justifications Videotape Group Problem Solving • 84 9th grade, average ability students in US city – Work in 21 groups of 4 • Not friends • Introducing 2 variable algebraic equations – 1st day of group work – No group work preparation – Work on problem for 30 minutes • Videotape & Transcripts – Two RAs coded each student turn – Krippendorf’s Content analysis Jay: A hundred eighty dollars. Ben: If we multiply by ten cents, don’t we get a hundred and eighty cents? • Ben – – – – – Disagrees politely New information Correct Justifies Question Multi-dimensional Coding Evaluation of the previous action – Agree ( + ), Neutral ( n ), Ignore/New topic ( * ), Disagree rudely (––), Disagree politely (–) Knowledge content regarding problem – New idea, Old idea, Null-content ( {} ) Validity – Correct ( ), Wrong ( X ), Null-content ( {} ) Justification – Justify ( J ), No justification ( [] ), Null-content ( {} ) Invitation to participate – Command ( ! ), Question ( ? ), Statement ( _. ) Invitational Form Decision Tree Minimize Number of Coding Decisions to inter-coder reliability • Minimize Depth of decision tree • Put highly likely actions at the top Do any of the clauses proscribe an action? • Yes, code as command (imperative) • No, is the subject the addressee? – No, are any of the clauses in the form of a question? • No, code as statement (declarative) • Yes, code as question (interrogative) – Yes, is the verb a modal? • No, should the described action have been performed, but not done? – Yes, code as a command – No, code as a question • Yes, Is it a Wh- question (who, what, where, why, when, how)? – Yes, code as an question – No, is the action feasible? • Yes, code as a command • No, code as an question Based on Labov (2001), Tsui (1992) Coded Transcript ID Fay Action Do ten times eighteen.

Bob I don’t know Cate Try another number? Dan Which number? [8 seconds of silence; each student looks at own paper] Cate [looks at Ana’s paper] Yours is much closer. So, try a number close to yours Dan [looks at Ana’s paper] Mine’s even closer Ana [looks at Dan’s paper] Oh! More messages get us closer Creativity dampener Kay Let’s try a hundred. Lee Ok. That’s a thousand. Tom And that’s one, so nineteen. Kay That’s like over nine hundred away. Jan Maybe it’s one of those trick questions. Tom Yeah, like it can’t be done.
