"Examining Student Conceptions of Covariation: A Focus on the Line of Best Fit"
with Stephanie Casey, Eastern Michigan University
12:00 p.m. Eastern Standard Time, May 12 th , 2015
Abstract: This webinar will present research regarding students' conceptions of the
line of best fit prior to formal instruction on the topic. Task-based interviews were
conducted with thirty-three eighth grade students, focused on tasks that asked them to
place the line of best fit on a scatterplot and explain their reasoning as they did so.
Results regarding descriptions and categorizations of students' meanings of the line
of best fit and criteria they use when placing it will be presented, including video
excerpts of the student interviews. Implications for the teaching and learning of the line
of best fit will be discussed
Logistics : The webinar will be conducted using the GoToWebinar software platform. A

You will see the live presentation on your computer screen and the sound of the
presentation will come through your computer. If you can listen to music or hear videos on
your computer, your computer has the capability for you to hear the presentation. For your
voice to be heard by the presenters, if you wish to ask a question, GTW gives viewers the
option of VoIP (voice over the internet) or a telephone option for U.S. and Canadian
