Greetings and welcome to an archived discussion based
on the Developing Mathematical Ideas modules, Building a System of Ten
and Making Meaning for Operations.
In these folders you will find conversations of several different educators
who were facilitating seminars based on BST and MMO shortly after they
were published. Often one facilitator raised a question based on preparation
for a session or an experience in leading a particular session and other
facilitators responded with their reactions. For the purposes of the
archive, facilitators’ names have been replaced with have been
pseudonyms. The only exceptions are that, Virginia Bastable and Deborah
Schifter, two of the authors of DMI who are also included in the conversations,
signed their comments.
The conversations were genuine in that they occurred as the facilitators
were working and even though these conversations are closed (that is,
you cannot add to them now), you can use these discussions to stimulate
your own thinking about issues and questions that come up as you lead
your own DMI seminar.
Reading the on-line dialogs that took place, you can consider, for example,
the advice one facilitator, Frederick, received about handling the tension
between expecting teachers to do homework to prepare for sessions and
wanting to encourage teachers to sign up for the BST seminar.
You might read about what happened in Liam's BST session 3 after he
expresses a concern about being able to sustain a focused discussion
but commits to do just that in the session.
In session 5 of BST, you can read what Dannon wrote to her participants
as they responded to this question, “What math issue or issues
are you working on for yourself right now? If you feel stuck and can
identify what’s blocking you, please do...”
You can investigate the discussions between Boris and Natasha as they
describe the experience of “living vicariously through each other’s
sessions” during their conversations of Session 3 of MMO.
These are just a few of the ideas you can explore by clicking on various
message threads in the archived DMI discussions. We trust you will find
this a stimulating and informative experience.
Virginia Bastable and Deborah Schifter
