1. Using Motion Probes to Enhance
Students’ Understanding of Position
vs Time Graphs

2. . Recent studies note that microcomputer-based laboratory (MBL) experiences are
helping students understand the relationships between physical events and graphs
representing those events (Barclay, 1986; Mokros and Tinker, 1987; Thornton, 1986;
Tinker, 1986).
• This thesis will utilize Vernier motion probes
and a WISE 4.0 project called Graphing
Stories, which will allow students to
experience the connection between a physical
event and its graphic representation.

3. Statement of the Problem
• International comparison research shows that although U.S.
fourth-grade students compare favorably, eighth-grade
students fall behind their foreign peers, particularly in their
mastery of complex, conceptual mathematics, a cause for
concern about the preparation of students for careers in
science (Roschelle et al. 2007).
• By utilizing technology and sparking their interest I should be
able to reduce the knowledge gap, regarding graphing
concepts, between my students by the time they reach high
school.

4. Background and Need
• Although many researchers can not find
conclusive evidence to say that MBL
techniques improve student understanding of
graphing concepts, I believe that most would
agree that it does. This thesis project will
attempt to show that the MBL approach
works.

5. Purpose of Project
• WISE is the common variable in a partnership between
Martinez Junior High School and UC Berkeley. UC Berkeley
has provided software, Vernier probes, Mac computers and
support with WISE 4.0. This unique opportunity to coordinate
with researchers from UC Berkeley is one reason I chose this
project. The other reason is to prove to myself and others
that Graphing Stories is valuable learning tool.
• My thesis will test the hypothesis that students will have a
better understanding of graphing concepts after working with
Vernier motion probes Graphing Stories and than the
students who work without the motion probes.

6. Project Objectives
• To test if an MBL approach increases student
understanding of graphing concepts
• Utilize the unique opportunity of the
partnership between UC Berkeley and
Martinez Junior High School
• Reinforce the idea that the project Graphing
Stories is learning tool
• Utilize students enthusiasm for technology

7. Summary
• I believe that students who use Vernier
motion probes in connection with Graphing
Stories will show a deeper understanding of
graphic concepts than students who do not
use the motion probes.
