Effect of Arduino Uno Based Microcontroller Media TrainerAgainst Student Learning Outcomes Psychomotor in the Basic Competencies Controlling the Input and Output Ports in Surabaya KAL-1 Vocational School Judging from the Level of Creative Thinking

The objectives of the study were: (1) to analyze the differences in learning outcomes between students who studied using Arduino Uno media trainers and students who studied using AVR media trainers at Surabaya KAL-1 Vocational School; (2) analyze the differences in learning outcomes between students who have a high level of creative thinking and students who have a low level of creative thinking at Surabaya KAL-1 Vocational School; (3) analyze the interaction between the use of media trainers and creative thinking on the learning outcomes of students of Surabaya KAL-1 Vocational School. The type of this research is quasy experiment using factorial 2x2 design, and data is analyzed using two-way Anava. The study found: (1) the average score of psychomotor domain learning outcomes (85.11) for students learning by using Arduino media trainers, significantly higher than the average score of psychomotor domains (74.80) for students learning using AVR media trainer; (2) the average score of psychomotor domains for students who have a high level of creative thinking (91.47), significantly higher than psychomotor domain learning outcomes for students who have a low level of creative thinking (78.09); (3) there is a significant interaction between the application of the media trainer and the level of creative thinking on the learning outcomes of the psychomotor domain.Key words: LED TV learning media, student response, learning outcomes, vocational students.
