Project Pathways • Partnership of ASU and five school districts • Primary Goal: • To produce a research-developed, refined & tested model of inservice professional development for secondary mathematics and science teachers • Core Strategies: • Four integrated math/science graduate courses + linked teacher professional learning communities (lesson study approach)
Local Conditions • Students • Arizona has the nation’s highest school dropout rates • Fewer than 25% of Arizona students scored “proficient” or higher on the 2003 National Assessment of Educational Progress of mathematics and science • Teachers • 58% of Arizona teachers do not hold a degree in the subject that they teach • Arizona teachers receive professional development that has been categorized as scattershot, seldom, and shallow • Spent an average two days per year in professional development activities • Statistics from NCES, 2003, Killion, 2002, Sowell, 1995 .
Pathways Objectives for Teachers • Deepen teachers’ understanding of foundational mathematics & science concepts and their connections • Understanding and use of covariational reasoning and function as connecting themes • Improve teachers’ reasoning abilities and STEM habits of mind (problem solving, scientific inquiry, engineering design) • Support teachers in adopting “expert” beliefs about STEM learning, STEM teaching, and STEM methods (See STEM BILT Taxonomy) • Focus on promoting content knowledge for teaching, e.g., the processes and complexities of acquiring understanding of key ideas. • Support teachers in reflecting on and modifying their classroom instruction
Intervention • Courses • Focus on connections and coherence • Focus on covariational reasoning and function as connecting themes • Focus on developing STEM habits • Model student centered instruction
Overview • Research that supports this focus: • Conceptual frameworks (based on multiple years of qualitative studies) have informed the emergence of a Function Inventory (Thompson, 1994; Carlson, 1998; Carlson, Jacobs, Coe, Larsen, Hsu, 2000; Oehrtman, 2004) • Qualitative research and problem solving framework (Carlson, 1998; Carlson & Bloom, 2005) have informed the emergence of a STEM ‘habits of mind’ framework • A characterization of effective problem solving behaviors
Revise Cognitive Frameworks The Reflexive Relationship Between Frameworks and Intervention • One Example Carlson & Bloom Problem Solving Framework -Describes effective mathematical practices Conceptual Frameworks (e.g., Covariation, FTC, Function) -Characterizes understanding (e.g., reasoning abilities, connections, notational issues) Theoretical grounding for -Designing curricular modules -Determining course structure -Instrument development Lens for researching emerging practices and understandings
Instruments for Assessing Pathways Progress and Effectiveness • Function Concept Inventory • 25 Item multiple choice instruments that has been validated over the past 7 years • Beliefs about STEM habits and STEM teaching • Developed--early in the validation process • PLC Observation Protocol • Still collecting qualitative data--not yet developed • RTOP • Already validated and published
The Bottle ProblemImagine this bottle filling with water. Sketch a graph of the height as a function of the amount of water that’s in the bottle
Mental Actions of the Covariational Reasoning Framework • MA1) Coordinating one variable with changes in the other variable • MA2) Coordinating the direction of change in one variable with changes in the other variable (e.g., increasing, decreasing) • MA3) Coordinating the amount of change of one variable with changes in the other variable • MA4) Coodinating the average rate of change of one variable (with respect to the other variable) with uniform changes in the other variable • MA5) Coordinating the instantaneous rate of change of one variable (with respect to the other variable) with continuous changes in the other variable • (Carlson, Jacobs, Coe, Larsen, Hsu, 2002)
Covariational Reasoning: A Foundational Reasoning Ability for Understanding and Using Big Ideas of CalculusDerivativeAccumulation
Problem Solving Process • (Carlson & Bloom, 2005)
Major Findings that Influenced Intervention Adaptations: • Pace of course, amount and nature of homework, and expectations for classroom participation influenced the level of conceptual learning and exhibition of problem solving behaviors for STEM teachers. • Multiple viewing and coding of classroom videos revealed • Development of a deep understanding of fundamental concepts such proportionality, rate-of-change and exponential growth is complex • Pacing, homework and enactment of classroom practices were issues • Adjustments were made to modules and homework
Select Findings: • Analysis of qualitative data revealed irregularities in teachers’ enactment of problem solving behaviors during class • Some teachers were not engaged in making sense of the tasks/problems during the classroom activities • Teachers sometimes pretended to understand when they did not • Teachers communication relative to the mathematics was often incoherent
In the third cohort explicit “rules of engagement” were negotiated • Explicit attention to enacting the Rules of Engagement during interaction or discourse • Speaking with meaning • Mathematical Integrity • Sense Making • Respecting the learning process of colleagues
Speaking with Meaning • Speaking with meaning implies that responses are conceptually based, conjectures are based on logic, conclusions are supported by a mathematical argument, and explanations are given using the quantities involved. • Examples: Contrast responses to the bottle problem.
Early results from cohort 3 are encouraging: • Shifts in teachers’ understanding of concepts was significant (e.g., PCA mean score shifted from 17 to 23) • The “rules of engagement” became spontaneous • Teachers reported that attention to speaking with meaning had impacted: • Their attention to student thinking, their communication patterns with students, their understanding of key ideas, etc. • Positive shifts were noted on STEM Beliefs instrument
Early results revealed perceived ‘factors of resistance” for shifting instruction towards coherent and conceptually focused lessons. • Textbook does not support teaching ideas or concepts • Standardized tests do not value understanding • Students are not smart enough to work thought provoking tasks • Teachers’ images of teaching involves “stand and deliver” instruction, procedural learning, memorization
Pathways Response: A Professional Learning Community (PLC) • A Pathways Professional Learning Community • 3-7 teachers who meet for 1-2 hours weekly to reflect on and discuss what is involved in knowing, learning and teaching concepts. (A school based facilitator is responsible for focusing the discussions.) • Activities of the PLC: • Unpack and discuss what is involved in understanding an idea • Discuss and evaluate student thinking (interview students) • Reflect on the effectiveness of instruction in promoting student learning • Eventually move to cycle of planning, developing, teaching, studying and refining conceptually focused lessons
PLC Intervention • Facilitators have received training to manage discourse among PLC members • Facilitators manage agenda developed by Pathways faculty • Explicit attention to enacting the “Rules of Engagement” during interaction or discourse • Speaking with meaning • Mathematical Integrity • Sense Making • Respecting the learning process of colleagues
Research Questions • What are the attributes of a “high functioning” PLC? • What variables promote “quality discourse” about knowing, learning, and teaching mathematics?
Methods: Grounded Theory • Videotaped, reviewed and coded videos of four PLCs • Teams of 2 RAs were responsible for coding each PLC throughout the semester. Initially coded for enactment of (and missed opportunities to enact) the rules of engagement • Documented emerging patterns • Share results weekly and collaborate to refine our original definitions
What We Are Learning • The facilitator is a critical variable in determining the quality of the PLC discourse • Facilitators varied relative to their: • Conceptual knowledge • Level of inquiry about PLC members’ thinking • Level of inquiry in regard to their own teaching • Commitment to the goals of the PLC • Ability to demand speaking with meaning among PLC members • Observable differences in PLC discourse relative to: Decentering
Facilitator Decentering • Definition • adopting a perspective that is not one’s own • Involves the ways a person adjusts his or her behavior in order to influence another in specific ways
Manifestations of Decentering • Facilitator makes no attempt to build a model of other member’s thinking • Facilitator explains and moves on • Facilitator appears to build a partial model of a member’s thinking • Facilitator explains; then asks questions to determine if a PLC member understood some aspects of her/his explanation • Facilitator appears to build a model of a member’s thinking, but does not use that model usefully in communication • Facilitator listens and/or asks PLC member questions and provides statements that indicate that he/she understands PLC member’s thinking, but facilitator reacts by explain her/his thinking again
Manifestations of decentering • Facilitator builds a model of a member’s thinking for the purpose of moving he/she to her/his way of thinking • Facilitator listens to a member’s thinking and recognizes that it is different than her/his own; then acts in ways to move this person to her/his way of thinking • Facilitator builds a model of a member’s thinking and acts in ways to understand the rationality of this member’s thinking • Facilitator questions a member to understand her/his thinking. Also, facilitator create a new model about how this member might understand his/her way of thinking.Facilitator then adjusts her/his interactions (questions, drawings, statements, etc.) to take into account the member’s thinking and how this member might understand him/her.
Summary Results • Five manifestations of decentering were observed • Facilitators who made efforts to understand the thinking and perspective of other PLC members (decentering) were better able to engage the members of the community in meaningful discourse • Facilitator’s level of understanding of the concept that was central to the lesson influenced the quality of the PLC discourse • Revealed by her/his questions, choice of tasks, and choice to pursue an exchange with a specific PLC member
Implications and Further Analysis • Continue to explore attributes of a facilitator that lead to “high quality” discourse among PLC members • Follow PLC members into classroom to ascertain relationships between PLC behavior and classroom behavior • Use new knowledge • Selection of facilitators • Improve PLC facilitator training • Theoretical framing for the Learning Community Observation Protocol
