WHY IT MATTERS TO YOU
The science talk format that helped elicit such a meaningful, productive class discussion may be useful to ISE educators who wish to foster such discussions in their programs. For ISE professionals, as for teachers, awareness of the need for student instruction in how to construct explanations jointly—with only guidance rather than answers from the instructor— recognizing the significance of the students responses to each other as they unfold, and the value of investing instructional time in meaningful discussion is part of the expertise of the educator, and could be included in professional development.
What Is The Issue?
Sociologists and other researchers have challenged the idea that scientific accomplishments and knowledge resides within an individual, but emphasize that scientific practices are social and distributed among many. This article demonstrates characteristics of how a similar dynamic played out in a classroom through one student’s discourse moves, as well as the teacher’s guidance. The goal is to help educators better recognize, assess, and promote these ideas in their everyday class interactions.
What Was The Study?
Using the Science Talks format (see Further Reading), this particular student presented a theory she had written in her journal to the class, which, although it was incorrect, contained scientific reasoning that the teacher used to build on the way the student was making sense of the world. In her presentation, the student’s discourse moves directly map onto professional science practice, and include:
- reviewing shared assumptions;
- citing the work of her peers; and
- connecting separate ideas from prior work into a description of the group’s current understanding.
- The class then collectively took up the ideas for further development, where they:
- created and shared multiple models and representations, using body parts or objects in the classroom;
- used and clarified language within the group, which then became a resource for proposing more precise and complex ideas; and finally
- negotiated and developed a new, shared explanation.
What Were The Findings?
The shared theory that resulted from this particular discussion was held, revised, and eventually abandoned throughout the teaching of several more units, as more data was incorporated into the student’s understandings. It should be noted that the teacher did not authoritatively make statements about the correctness of the ideas under discussion, but used the science talk protocol to let students negotiate their ideas.
