Moving the Graphing Calculator to the Mobile Platform:
Results of a Two
Year Study

Dr. John Ehrke

Abilene Christian University


Mobile learning technologies are poised to significantly impact the future of the
graphing calculator platform. The effect of integrated devices (devices which blend
productivity, social media, and computing) on educational design in mathematics
remains l
argely unexplored. In this report, we analyze the results of a

sections of a general education mathematics course
. Student
performance data and student perceptions of usability are compared across two
platforms: the SpaceTime® m
obile computing app and the Texas Instruments TI
84® series of graphing calculator. Pedagogical implications
of moving the
traditional graphing calculator to the mobile platform are discussed.

Presentation Content:

As we look across the educational
landscape mobile technologies are rapidly gaining
acceptance as teaching tools in a variety of content areas. New uses of the
technology platform appear almost daily. Just as advances in electronics and display
improvements led to the birth of today’s gr
aphing calculators, similar technological
advances in mobility and multi
touch interfaces are poised to take the reins in
driving the graphing calculator to the mobile platform.

Does the mobile platform have the potential to improve student performance
when compared to the traditional handheld graphing calculator?

Are there notable differences in usability between the two platforms?

What is the current state of mobile computing app design, and how might
insight into students’ usage of the device inform f
uture design of computing

What curricular changes and instructional design changes must occur to
successfully implement these devices?

To what extent does a mobile device make a difference in informal learning?

These are but a few of the questions,
this study has set out to discover. As more
educators begin to experiment with these new devices and a wider range of
calculator apps and computing programs become available the need for sound
pedagogy and researched implementation of such devices will gr

The presentation will consist of guiding the audience through the methodology and
results of the study, and to give them a glimpse of what a mathematics classroom
built around access to mobile computing looks like.


Session will be conducted primarily from an iPad 2 using screen mirroring. I
want to give the audience the sense of what students actually see in the
classroom. I will bring all the necessary attachments, but would require
wireless network access and sou

I will also use a laptop and will require hdmi, dvi, or vga compatible
connections. I will bring all the connectors myself.
