ab: Summary: To support students’ development of concepts in mathematics, the
use of technology is often encouraged. Technology can contextualize
learning and provide a meaningful setting for mathematical ideas. Most
teachers are supportive regarding the use of technology to encourage
learning and understanding in mathematics. However, using technology
can present many challenges. Particularly, technology training is not
as strong as it could be in supporting teachers’ growth and ability
to create lessons, and most teachers would like support in using
technology in the classroom. To address this concern, this article
presents a guide for an activity using graphing calculators and
Calculator-Based Ranger$^{\text{TM}}$ 2 (CBR) as the technology to
support understanding of position/time graphs with preservice
elementary school teachers. This activity supports a grade 6 standard
from the Common Core State Standards for Mathematics (CCSSM) that
encourages students to see the relationship between variables in
real-world situations. Students should “analyze the relationship
between the dependent and independent variables using graphs and
tables”. This activity allows students to experience how their
distance from the CBR (dependent variable) changes the graph as related
to time (independent variable). CBRs are sonic motion detectors
designed to be used with graphing calculators (specifically the TI-83
Plus and the TI-84) and can collect data on motion, including distance,
velocity, and acceleration. Additionally, one of the preservice
teachers taught the same lesson individually to a fifth-grade student
who sometimes struggles in mathematics. The teacher’s reflections are
included. (ERIC)
