Abstract
This study investigated Geometer’s sketchpad (GSP) and students’
geometry learning motivation and problem solving ability. In this study
pretest-posttest quasi experimental design with non equivalent comparison
group was used. Two groups of 9th grade were selected using purposive
sampling based on their first semester mathematics achievement. The two
groups were assigned as experimental group (n=68) and comparison group
(n=65) using lottery method. During 4 weeks instruction, the Intervention
group received instruction with the GSP while the other groups were
taught with traditional paper-pencil instruction. Data of study were
collected through Motivation Measuring Questionnaire (MMQ) containing
two parts: Self Efficacy Measuring Questionnaire (SEMQ), Effort
Measuring Questionnaire (EMQ) and Problem Solving Ability Measuring
Questions (PSAMQ). The content Validity Indices (CVI) were .79, .84
and .83 for SEMQ, EMQ and PSAMQ taken in order. Moreover the
internal consistence had Cronbach’s alpha values of .873 and .902 for
SEMQ and EMQ respectively. Data were analyzed using the paired
samples t-test, independent samples t-test and regression analysis.
Findings of the study indicated that there was no statistical significant
difference between the Intervention and comparison groups prior to the
treatment in both motivation and problem solving ability. But, there was
statistical significant difference between the Intervention and comparison
groups after the treatment in both motivation and problem solving
ability. That is the Intervention groups showed better improvements than
the comparison groups. For Intervention groups, the low achievers and
medium achievers showed better improvement as compared to the high
achievers. It is recommended that instruction in geometry should be
supported with appropriate use of GSP in order to improve students’
motivation and problem solving ability
