I had a super-great learning experience in class this week. My group and I had felt our data story poster was near completion two weeks ago, but upon seeing it again yesterday with only a data table and no graphs, we decided graphing would help others understand the data and our story better. It took some hard thinking and discussion to decide how we wanted to show phone subscriptions over time to GDP of different countries over time, but finally decided for a reason we couldn’t really put a finger on, that two graphs would work well: one showing phone subscriptions to time and the other showing GDP of the three countries we chose over time.
Our brains warmed-up nicely as we traveled the room of posters, discussing our questions and thoughts of the data stories as we went. At one point we reached a poster that was challenging to understand at first, comparing U.S. military and education expenditures to each other. After looking and discussing further we did understand, and again, didn’t really put our finger on exactly why the graph had been tricky to understand. Finally, back at our own poster, we saw a post-it question from another group asking why didn’t we put our two graphs together as one. That’s when I really got it, that we didn’t put them together because if that meant comparing phone subscriptions to GDP, it might imply that one determined the other. We didn’t necessarily conclude that GDP determined phone subscriptions, we just wanted to show the trends of each GDP and phone subscriptions over time. We wanted both to be compared to time (as our x-axis) and would have had trouble combining GDP and phones for the y-axis in a meaningful way.
This group task of the entire process of creating the data story, representing it in a poster, discussing other posters for understanding, and finally considering where others thought our poster could share understanding better, made me really understand an aspect of graphing quite consciously. It was more meaningful for me to experience why my group and I felt more comfortable sharing our data in a certain way, considering other ways other groups shared theirs, and then thinking about ours again together that my understanding deepened.
Now, not only do I have a deeper understanding of graphing, but I also have a deeper, more meaningful understanding of the value of group tasks in the learning process. I will definitely take this awareness of the value of group tasks for understanding with me into classrooms. I guess I am just left wondering when does the teacher need to step in if understanding is not coming through the group tasks? How patient with the process should the teacher be?
