Peningkatan kompetensi siswa sangat bergantung pada model pembelajaran dan kemampuan penalaran formal siswa. Penelitian ini bertujuan untuk: (1) menganalisis perbedaan kompetensi antara siswa yang diajarkan dengan model pembelajaran PDEODE dan siswa yang diajarkan dengan menggunakan model pembelajaran langsung pada mata pelajaran DLE di SMK Raden Rahmat Mojosari, (2) menganalisis perbedaan kompetensi antara siswa yang memiliki TKPFT dan siswa yang memiliki TKPFR pada mata pelajaran DLE di SMK Raden Rahmat Mojosari, (3) menganalisis interaksi antara penggunaan model pembelajaran dan TKPF terhadap kompetensi siswa pada mata pelajaran DLE di SMK Raden Rahmat Mojosari.

Penelitian ini adalah jenis penelitian eksperimen yang menggunakan desain analisis faktorial. Instrumen pengumpulan data berupa lembar observasi kompetensi sikap sosial komponen pasif, lembar tes kompetensi pengetahuan komponen pasif, lembar tes kinerja kompetensi keterampilan komponen pasif dan lembar tes kemampuan penalaran formal siswa.

Berdasarkan hasil penelitian, dapat disimpulkan bahwa: (1) terdapat perbedaan kompetensi antara siswa yang diajarkan dengan menggunakan model pembelajaran PDEODE dan siswa yang diajarkan dengan menggunakan model pembelajaran langsung pada mata pelajaran DLE di SMK Raden Rahmat Mojosari, (2) terdapat perbedaan kompetensi antara siswa yang memiliki TKPFT dan siswa yang memiliki TKPFR pada mata pelajaran DLE di SMK Raden Rahmat Mojosari, (3) terdapat interaksi antara penggunaan model pembelajaran dan TKPF terhadap kompetensi siswa pada mata pelajaran dasar listrik dan elektronika di SMK Raden Rahmat Mojosari.

Increasing student competency is very dependent on the learning model and students' formal reasoning abilities. This study aims to: (1) analyze the differences in competencies between students taught with PDEODE learning models and students taught using direct learning models on DLE subjects in Raden Rahmat Mojosari Vocational School, (2) analyze differences in competencies between students who have TKPFT and students who have TKPFR on DLE subjects in Raden Rahmat Mojosari Vocational School, (3) analyze the interaction between the use of learning models and TKPF on student competencies in DLE subjects at Raden Rahmat Mojosari Vocational School.

This research is a type of experimental research that uses factorial analysis design. The instruments of data collection were in the form of observation sheets of competency, social attitude, passive components, knowledge competency test sheets of passive components, passive skills competency test performance sheets and test sheets of students' formal reasoning abilities.

Based on the results of the study, it can be concluded that: (1) there are differences in competencies between students taught using the PDEODE learning model and students taught using direct learning models on DLE subjects in Raden Rahmat Mojosari Vocational School, (2) there are differences in competencies between students who have TKPFT and students who have TKPFR on DLE subjects in Raden Rahmat Mojosari Vocational School, (3) there is an interaction between the use of learning models and TKPF on student competencies in basic electricity and electronics subjects at Raden Rahmat Mojosari Vocational School.
