Previously, we described a Team-Based Ubiquitous Learning Model on Cloud Platform Model (PITTA Model). In this paper, we aimed to demonstrate the value of this model by compare learning achievement and creative problem-solving ability using the PITTA model of learning, compare between experimental group and control group by The Randomized Posttest-Only Control Group Design. The sample group comprised students from Bunditpatanasilpa Institute of Fine Arts who were enrolled in the Innovation Information Technology and Communication in Education course during the second semester of Feb-Mar 2023. A total of 50 students from two classrooms were selected using cluster random sampling. The students were divided into two groups: one consisting of 25 students who participated in PITTA model learning activities, and another group of 25 students who engaged in conventional learning activities. The research employed two main instruments: the learning achievement test and the creative problem-solving ability assessment test. Statistical analyses included the use of measures such as mean (x bar) and standard deviation (SD), as well as One-way MANOVA. The research findings revealed that the group of students utilizing the PITTA Model in their learning activities exhibited higher levels of learning achievement compared to the group engaged in regular learning activities, with statistical significance observed at the 0.05 level. Furthermore, the students who participated in learning activities based on the PITTA Model demonstrated superior creative problem-solving abilities compared to those involved in conventional learning activities, again reaching a statistical significance level of 0.05.
