The purpose of this study is to construct the developing materials of mathematics process skills learning on Trigonometry and applications by using Adobe Flash CS6 program effectively. We studied, collected the information and methods to construct the materials by the Adobe Flash CS6 from O-sot Linux TH Channel in YouTube.The samples consisted of 2 classes of Mattaomsuksa 5 at Loengnoktha School, Yasothorn, 30 students in each, during the academic year of 2014. The two classes were randomly selected and assigned as an experimental group and controlled group. The experimental group was used Adobe Flash CS6 Program, while the controlled group was used without Adobe Flash CS6 Program.The instruments used for collecting data were Pretest, Posttest and T-test. The duration of the experiment was 6 periods, 50 minutes each. The statistical procedures employed were mean (xˉ), standard deviation (SD), and paired samples (t-test).
The findings of the study revealed that the Mattayomsuksa 5 students learning with the developing materials of mathematics process skills learning on Trigonometry and applications by using Adobe Flash CS6 program was significantly higher than that of those using without Adobe Flash CS6 program at the 0.18 level.
