Tamara L. Clegg School of Interactive Computing Georgia Institute of Technology Kitchen Science Investigators: Promoting Identity Development as Scientific Reasoners and Thinkers
Candyce 6thGrade KSI Participant
Candyce Tammy: Okay, and then what do you, what do you want to be when you grow up?Candyce: [pause] I want to be a, well I've been thinking about being a chef now that I'm in KSI. So I think that would be a really interesting job.Tammy: Okay, what makes you think that'll be an interesting job?Candyce: Because, okay, if I'm a chef, then most chefs just put ingredients in there, but if I'm a chef, my food'll turn out like exactly the way I wanted it, and it'll probably be even better than I expected because I'll actually think about the way that I wanted it instead of just putting ingredients in there and following a recipe. Like I can change up the ingredients because I'll know what the thickeners do and I'll know what the, these type of liquids do. Yeah, so I can change it up to get it the way I want it uh, specifically.

Barriers to Science Identity Development • Many learners don’t recognize utility of science • Useful only in school • In school they face • Difficulties connecting science to • The real world - their everyday lives • Their own interests and goals (Chinn & Malhotra 2001) • Tensions between science and home community • Minorities: language use (Brown 2004) • Low SES groups: Silent and obedient in school (Brickhouse & Potter 2001)
Promoting Identity in Science • Help learners see themselves as people who can and do use the practices and knowledge of science • My Approach: Design Transformative Learning Environments • Help learners develop scientific identity by engaging in scientific practice Professionally Personally
Transformative Learning Environments • Definition: Environments designed to help learners come to see themselves in new ways by enabling them to identify and explore potential roles for themselves • Not to be confused with transformative learning theory (Mezirow 1975, Cranton 2002)
My Research Questions • Design-based research aiming to understand • (Theory) How the development of scientific reasoning identity and disposition happen • (Practice) How to help kids develop identity and disposition as scientific reasoners and thinkers • Identity and Disposition? • Identity: how you see yourself • Disposition: the things you take initiative to do • Clearly, they are related
Disposition Scientific inquiry Theoretical Framework
Identity as Discourse Identity • Discourse: Any combinations of social and historical ways of being that can cause one to be recognized as a certain type of person (Gee 2001) • Discourse: • Ways of • Speaking & writing • Acting & Interacting • Using face or body • Feeling, believing, • & valuing • Using objects, tools, • or technologies
Scientific Practice Authentic scientific practice • In the context of real world problems • Full range of variables can be tested and outcomes may be unknown • Procedures for answering questions chosen at least partially by participants • Chinn & Malhotra 2001; Gleason & Schauble 1999 Definition: The reasoning relevant to the pursuit of explaining, predicting, and controlling of empirical phenomena Creating and using evidence Designing experiments According to scientific standards Chinn & Malhotra, 2001; Osborne et. Al, 2001; Gleason & Schauble 1999
My Hypothesis: Developing Disposition • Goal for learners: • Recognize when something is scientific • In a situation where scientific reasoning is relevant, they engage
Thesis Statement • Engaging learners in scientific practice in the context of different Discourses they participate in will lead to their development of scientific dispositions, which will in turn promote learners’ scientific identity development.
One Transformative Learning Environment Kitchen ScienceInvestigators
Starting With Learners’ Interests and Goals - Kitchen Science Investigators • Design the Context for learning: After-school or summer camp learning environment where kids learn science and scientific reasoning skills through cooking • Intention: Kids will see relevance of science through experiencing the value of scientific reasoning for them • Help them see food as an object of investigation through play • Transition them to engagement in authentic scientific practice • Analyze development of disposition and what’s causing or prohibiting it
Kitchen Science Investigators • Three aspects that help promote identity development and science learning • Activities • Technology • Facilitation • Activities • Cooking Experiment – Science Experiment • Progress to more complex dishes
Children tend to: • Role of Technology • Prompt learners to focus on the scientific reasoningwhile cooking Gardner, Clegg, Williams, & Kolodner International Conference of the Learning Sciences, 2006 • Structured & Free-form technology support Clegg & Kolodner 2007 Research and Practice in Technology Enhanced Learning 2(3), 239-266 Forget the purpose of experimentation End investigations prematurely Fail to recognize importance of scientific situations (Gleason & Schauble 1999, Quintana et al. 2004)
Comparing Variation Results Group Name & Variation Observation Questions
Free-form Technology Support Creating stories and explanatoids from experiments and investigations
Role of Facilitators • During whole-group discussions • Guiding Conversations • Explaining Science • During small-group work • Modeling Scientific Reasoning Processes • Between sessions • Design activities based on learners interests and understanding
Research in this context Methods
Analyzing Development of Disposition and what’s causing (or inhibiting) it In the context of KSI: • Q1: What is the range of Discourses learners are engaging in? • Q2: How is the scientific reasoning Discourse influenced by participation in those Discourses? • Q3: How does participation in KSI influence learners’ disposition to reason scientifically?

Data Analysis • Coding: Discourse Participation and Development • Scientist • Chinn & Malhotra, 2001 framework • Chef • Actions, questions, values, etc. pertaining to creating and preparing dishes • Friend • Social conversation or play • Laughter, personal conversation, playful, arguments, etc. • Coding Order • Interview data • Changes, shifts, and developments in Discourses • Causes • Selected observation days (5-6 days per learner) • Coded observation days (active participation) by Discourse
Discourse Development • Within each Discourse: • Ways of • Speaking or writing • Acting or Interacting • Using face or body • Feeling, believing, • or valuing • Using objects, tools, • or technologies Looked within each Discourse to understand how participation shifted over time in each
Influences of Other Discourses on the Scientist Discourse? • Across each Discourse: • Ways of • Speaking or writing • Acting or Interacting • Using face or body • Feeling, believing, • or valuing • Using objects, tools, • or technologies Looked for connections from each Discourse to the Scientist Discourse to understand how participation shifts in each Discourse influenced Scientist Discourse
Scientific Disposition • Participation in Scientist Discourse • Amount • Complexity • Contexts • Overarching ideals about, values of doing science • (Bereiter, 1995; Gresalfi, 2006; Katz 1993)
Candyce • Hated science class • Teacher • Experiments • Switched classes • KSI • Descriptive observations became goals • Used science experiments to achieve • Developed “craving for knowledge” 6th Grade Interests: Science, Cooking Participation Style: Quiet/Vocal
Candyce 6th Grade Interests: Science, Cooking Participation Style: Quiet/Vocal Okay, what are my strengths as an investigator? I like finding things out because I'm like the type of person who will want to know something and who loves getting information. So I'm good at that. That's what strength [I have]. Yeah, I have a craving for knowledge.
Malaysia • Science class boring • Stare at teacher • Read book • KSI • Cooking expertise – pasta and fruit tart • Understood starch absorption • Scientific terminology became goals for dishes • Increased science interest 6th Grade Interests: Social, Cooking Participation Style: Vocal
Malaysia M: Cause, [KSI]'s like ↑fun, but it's educational at the same time. So, and then it'll help you understand science more, cause kids don't really understand that boring way cause they fall asleep and stuff, so if you do KSI, you can be excited and enthusiastic and then you'll be learning about science at the same time.T: So, what do you mean by boring stuff?M: Like sitting in the classroom opening your textbook or sitting there staring at the teacher. 6th Grade Interests: Social, Cooking Participation Style: Vocal

Scientific Disposition • Relevance of science for achieving goals • Experimentation • Scientific understanding • Connection of science to real world experiences and interest • Curiosity – desire to know more
Implications for the Design of Transformative Learning Environments (TLE)
Friends & Scientists: Implications for Design of TLEs • Activities • Real world context allows for shared experiences - bonding • Whole group & small group conversations • Combination of diverse learners • Particularly older learners interested in science • Didn’t always work • Offering choice • Promotes working together based on interests Clegg & Kolodner American Education Research Association, 2010
Chefs & Scientists: Implications for Design of TLEs Activities • Hard to predict when learners will ask questions or become interested • All activities designed in the context of achieving learners’ goals • Make them natural to refer back to • Ability to participate and make mistakes Clegg, Gardner, & Kolodner, International Conference of the Learning Sciences, 2010
Chefs & Scientists: Implications for Design of TLEs Facilitation Recognize when learners’ interests are piqued/dwindling Capitalize on those moments Find opportunities for learners to answer their own questions Unplanned scientific activities Selecting appropriate practices Build off of interest of learners Clegg, Gardner, & Kolodner, International Conference of the Learning Sciences, 2010
