The purposes of this study were 1) to compare student achievement of Matthayomsuksa 5 students  in Chemistry subject   on the topic “ Chemical equilibrium ” between groups using  Learning Cycle with application  Model and  IPST  Model. 2) to compare  Scientific attitude of Matthayomsuksa 5 students  in Chemistry subject on the topic “ Chemical equilibrium ” between groups using  Learning Cycle with application  Model and  IPST  Model.  The sample use in this study are to assess the student’s retention in learning at two-year deal through cooperative learning. The samples used in this study are the of  Matthayomsuksa 5 students at Rattanakosinsompote bowonniwet salaya School,  Nakornprathom province , Secondary  Education Service Area office 9. A total of 2 classroom or 2 groups of student  were tested during the second semester, in academic year 2015,There are 40 students in the experimental group and 38 students in the controlled group.

The results should that.

1. The student achievement of Matthayomsuksa 5 students  in Chemistry subject on the topic “ Chemical equilibrium ” between groups using  Learning Cycle with application  Model and  IPST  Model. was different in the statistically significant at .05 level

2. The Scientific attitude of Matthayomsuksa 5 students  in Chemistry subject on the topic “ Chemical equilibrium ” between groups using  Learning Cycle with application  Model and  IPST  Model. was different in the statistically significant at .05 level
