Abstract: The Appliction of Creative Problem Solving and IDEAL Problem Solving Models Base on Experiencing Over Viewed from Student Motivation. The purposes of this research were to know : 1) the effect of student achievement between student who learnt using Creative Problem Solving and IDEAL Problem Solving Models 2) the effect of student achievement between student who had high and low motivation, 3) the interaction between methods and motivation toward student achievement. From the data analysis can be concluded that : 1) there was no effect of student achievement between student who learnt using Creative Problem Solving and IDEAL Problem Solving Models (P= 0,842); 2) there was an effect of student achievement between student who had high and low motivation, (P= 0,001) 3) there was an interaction between methods and motivation toward student achievement (P= 0,017) Keywords: Creative Problem Solving, IDEAL Problem Solving, Experiencing, motivation, student achievement.
