Strengthening Vocational High School Teachers' Pedagogical Competence in Developing AI-Based Learning Materials through Prompt Engineering Training

This paper reports a community service program designed to strengthen vocational high school teachers' pedagogical competence through prompt engineering training to support AI-assisted instructional design. The program was conducted as an in-house training at SMK Negeri 1 Bulakamba involving 90 teachers from different subject areas. Activities included initial needs mapping, hands-on training on developing teaching modules, lesson plans, and assessment items using structured prompts, followed by post-training mentoring. Observations and artifact documentation indicate a shift from manual preparation toward a more systematic design of teaching modules, lesson plans, and assessment instruments with clearer alignment among learning objectives, learning activities, and assessment. Voluntary feedback from 18 participants indicated positive perceptions, with mean scores ranging from 4.44 to 4.69 on a 1-5 scale, and high acceptance of the training (61% very good; 39% good). The findings suggest that prompt engineering training was well received and may support more structured instructional planning in vocational education.
