random sampling techinique that were divided into 39 in experimental class, 40 in
comparative class and 40 conventional class. The instrument used in this study was
a mathematics problem-solving ability essay test. The data were analyzed using
One Way ANOVA and Sceffe test. The result showed that there was a difference
in terms of problem-solving ability in mathematics among the students who used
online problem posing, problem posing and conventional learning. The result of
Scheffe test showed that students’ problem-solving abilitiy in mathematics that
