Abstract:
The objective of this research was to 1) develop a project – approach activity set through experience of sufficiency economy theory for preschool children, 2) study an effectiveness index of students who study by the project – approach activity set through experience of sufficiency economy theory for preschool children and 3) compare pre-test and post-test achievement by the project – approach activity set through experience of sufficiency economy theory for preschool children. The population for this research was 215 students of the nursery at Thetsabanthakhlong 1 School. The sample size included 34 students in class of 1/4 by simple random sampling. The instruments used in the experiment include the project – approach activity set through experience of sufficiency economy theory for preschool children, third items of the achievement test as 10 questions, and the form of observation behavior integrated thinking.
The results of the research indicated that :
1. Development of project – approach activity set through experience of sufficiency economy theory had an effective 81.99/83.53 rate, higher than the criteria of 80/80.
2. The effectiveness index of project – approach activity set through experience of sufficiency economy theory is 0.59. Therefore, the project – approach demonstrates an effect to achievement for preschool children increase of 59 percent.
3. Post-test score is higher than pre-test score by a statistically significant .05
