A development of Physics teachers’ conceptual understanding through the CIPPA teaching model on Vector concept.

This research aimed to improve conceptual understanding about Vectors through the CIPPA teaching model combined with the Eissco experimental set for 15 first-year graduate students in the academic year 2024. The 13 multiple choice items of the Test of Understanding of Vector (TUV) were used to test the understanding of the Physics teacher students as a pretest-posttest. The test covered 6 concepts (Direction, Magnitude, Component, Vector representation, Addition and Subtraction). The research statistics used were the paired-sample t-test and Normalized Gain . The results shown that the average percentage of correct answers after instruction is significantly higher than before instruction (p<0.05). Additionally, the class average normalized gains was 0.89, as a high range. Therefore, the CIPPA teaching model effectively enhances graduate students' knowledge.
