Data analysis resulted in the emergence of three central categories of Process
Behaviors generalizing the discipline-specific frameworks for STEM inquiry and three
categories of Dispositional Behaviors related to their discourse. A central
construct of Decentering also emerged for following facilitator moves to manage
the discourse. Four categories of Teacher Beliefs that influenced their ability
or willingness to change teaching practices emerged.
Process Behaviors. Process behaviors focus on the interactions within a PLC to resolve identify and resolve problems related to STEM content, instruction, student thinking, etc. Generalizing the three discipline-specific frameworks helped us identify and understand instances of similar behaviors and interactions across the STEM disciplines. We subsequently drew on John Dewey's constructs of inquiry and emergence in cognitive tool use (Dewey, 1910; Hickman, 1990) as we identified and characterized three central categories of behaviors related to scientific inquiry:
doesn't make sense": How taking an inquiry stance affects group interaction and conceptual
To illustrate the role of process behaviors, we will present a video case of one PLC whose typical interaction was not productive in terms of developing conceptual reasoning or effective STEM behaviors. However, there were some notable exceptions, sometimes as a result of a particular activity or intervention by the instructor, but also emerging from the group. The dominant mode of interaction for this group was driven by two participants. One of these participants consistently attempted to make connections between various representations leading regularly to him pointing out contradictions in the group's work. He was typically not able to engage the remainder of the group in addressing these problems. The second dominant participant regularly tried to explain away these contradictions often not fully understanding the issue and offering illogical resolutions. We found the more productive episodes were characterized by radically different process behaviors.
Dispositional Behaviors. Each of the discipline-specific frameworks include attributes of the individual such as affective qualities and metacognitive skills. We built on observable aspects of these attributes to identify and characterize dispositional behaviors which converged around three central categories:
From deference to promoting intellectual integrity: Understanding a
trajectory of teacher collaboration
To illustrate the role of dispositional behaviors, we will present the trajectory of a group of four high school math and science teachers during the first semester of the Project Pathways sequence. We discuss the changes (or lack thereof) of the group members and argue that they are best understood in the context of the evolution of the entire group's dynamics. Most compelling was the range in variation in the changes of STEM Behaviors across the teachers in this group. For example, one of the teachers made significant improvements over the semester related to his covariational reasoning and in the way he interacted with the others in his group. On the one hand, this change was enabled by specific dynamics of the group such as the eagerness of others for his help and their willingness to indicate to him when they did not understand. Reciprocally, this teachers' reactions encouraged more of this sort of openness, modeled productive dispositional behaviors, and positively influenced others' opportunities to learn. However, for the second teacher, we saw very little change in covariational reasoning and only superficial changes in the nature of his interaction. While his content knowledge was particularly strong as measured by our assessment instruments, his calculational orientation and lack of attention to others' understanding constrained his peers' willingness to engage and their opportunities to learn. This style of interaction was reinforced, however, by other teachers' compliance in receiving answers they did not understand. Thus the group reacted in seemingly contradictory manners in response to these two teachers, actively encouraging conceptual dialog over calculational dialog with the first teacher described above but encouraging the opposite from the other teacher. We resolve this in terms of the interaction within the whole system and by accounting for different aspects of the classroom tasks or of the group communication being taken as problematic by different teachers at different times.
Beliefs and Attitudes. The project documented shifts in teachers' views about the methods and nature of mathematics and science using several survey instruments and analysis of interview and PLC data. Coding of these beliefs converged around four categories:
between Process Behaviors, Dispositional Behaviors and Beliefs. We found that project
teachers primarily interacted from two different perspectives, illustrated as parallel
planes in Figure 1. From a "teacher perspective," they focused on issues about students'
thinking and learning or clarifying content to a colleague. From a "learner perspective,"
they wrestled with understanding the content themselves. While teachers often switched
between these perspectives, we never observed an individual actively participating from
both at the same time. Although, the perspectives parallel one another in the sense of
containing the same relationships between attributes and consisting of similar language
and tools, we observed that effective communication required participants to either take
the same perspective or for some to be teaching directly to the active learning issue of
the other teachers.
Decentering and Facilitator Strategies. Tracking the facilitation abilities of PLC facilitators revealed interaction patterns between the facilitator and other PLC members that influenced the quality of inquiry among the group. Our analyses also revealed that to actively facilitate teachers in a PLC requires that the facilitator "place" her or himself in the other members' shoes. "Placing oneself in another's shoes" is a classic instance of what Piaget (1955) identified as decentering, or the attempt to adopt a perspective that is not one's own. Steffe and Thompson (2000) extended Piaget's idea of decentering to the case of interactions between teacher and student (or mentor and protege) by distinguishing between ways in which one person attempts to systematically influence another. Analysis of the facilitators revealed five manifestations of decentering, ranging from the facilitator showing no interest in understanding the thinking or perspective of other PLC members to the facilitator building a model of other members' thinking, respecting their internal rationality, and adjusting her/his actions to account for these perspectives.
