The experiment was conducted in kindergarten classes, with two each from Kindergarten A and Kindergarten B grades, with a total of 80 students participating. A test and a questionnaire were used to collect data, where the test was used to measure creativity and the questionnaire for character variables. A descriptive and inferential statistical analysis method was used for data analysis, using MANOVA. The results show that there is an impact of learning a hypothetical deductive learning cycle model based on Tri Pramana on personality and creativity partially or simultaneously. It can be seen from Sig. value < 0.05. The study concludes that the application of a hypothetical deductive learning cycle model based on Tri Pramana has a significant effect on students' personality, creativity as well as creative thinking ability. This learning model can thus be recommended as an alternative to personality development and creativity in childhood.
