This study aims to improve student learning outcomes through the implementation of direct learning models that are supported by learning videos. Class action research refers to Kemmis and McTaggart's designs, which are carried out over two cycles. The subjects of the study were students of class X LVE 7 at VHS Dharma Bahari Surabaya. Data were collected using test and observation instruments. Test and observation data were analyzed descriptively based on standardized study completeness criteria. The results of this study found that student learning outcomes consistently increased from the pre-test scores, the value of the first cycle, to the value of the second cycle. Based on the pre-test score data, it is known that there are 16 or 53% of 30 students who reach the complete category. Learning outcomes are then improved in the first cycle, where there are 19 or 63% who reach the complete category. Meanwhile, in cycle II there were 23 or 77% of students who reached the complete category. This increase occurred consistently so that it was concluded that the use of direct learning models supported by learning videos was very effective for the learning of class X LVE 7 students at VHS Dharma Bahari Surabaya.

Pandemi Covid-19 telah merubah pola belajar siswa di seluruh dunia yang sebelumnya dilakukan secara tatap muka dan sekarang telah beralih menuju pembelajaran daring. Namun yang menjadi permasalahan adalah tidak semua sekolah siap untuk melaksanakan pembelajaran daring dalam waktu yang cukup lama. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk melatih para peserta dalam: (1) menggunakan platform google classroom; (2) menggunakan platform zoom cloud meetings; dan (3) menggunakan web tool quizizz. Kegiatan PKM ini dilakukan menggunakan metode pelatihan dan pendampingan. Subjek kegiatan atau perserta pelatihan berjumlah 50 orang guru. Waktu kegiatan dilaksanakan selama dua hari yakin tanggal 20 hingga 21 Maret 2020 yang diselenggarakan di SMK Dharma Bahari Surabaya. Hasil dari kegiatan PKM ini adalah secara berurutan dari 50 orang guru sebanyak 34%, 50%, dan 8% peserta masuk kategori “sangat baik”, “baik” dan “cukup” dalam mengoperasikan google classroom, sedangkan 8% lainnya masuk dalam kategori “kurang”. Selanjutnya, secara berurutan sebanyak 40%, 52%, dan 2% peserta masuk kategori “sangat baik”, “baik” dan “cukup” dalam mengoperasikan zoom cloud meetings, sedangkan 6% lainnya masuk dalam kategori “kurang”. Kemudian, secara berurutan sebanyak 30%, 56%, dan 10% peserta masuk kategori “sangat baik”, “baik” dan “cukup” dalam mengoperasikan web tool quizizz, sedangkan 4% lainnya masuk dalam kategori “kurang”.

This study aims to analyze the effect of using Collaborative Problem-Based Learning (CPBL) on students' problem-solving skills. This study used a 2x2 factorial design, in which the selection of experimental and control groups was determined with convenience sampling. The data analysis technique of this research is divided into two types, namely the prerequisite analysis test and hypothesis testing. The findings of this study concluded that students who studied with CPBL had significantly higher problem-solving skills than students who studied with Direct Instruction (DI). In addition, high problem-solving skills were generally owned by students with high initial skills. Meanwhile, the complete the results of the hypothesis test this study also showed a significant interaction between the learning model and initial skills on students' problem-solving skills in internal combustion motor competences. This shows that the selection of the right learning model is needed according to the initial skills of students so that problem-solving skills can be adequately developed. Thus, it is hoped that vocational school students can become graduates who can compete in the world of work.

Lack of media used in teaching and the conventional method used are also become the factors which influence the less student’s competency achieved in practical learning of motorcycle tune-up. This study aims to develop the student’s competency in motorcycle tune-up by applying the Troubleshooting teaching method towards undergraduate students in Education of Mechanical Engineering department. This study used Classrom Action Research (CAR) which used 26 students as subject. They are Undergraduate Student in department of Education of Automotive Mechanical Engineering, Unesa, Indonesia. This study used test method to evaluate the student’s competency in motorcycle engine tune-up. Based on the achieved data, it is then analyzed descriptively. This troubleshooting teaching method was able to develop student’s study result (student’s competency), started from 81,6 in cycle 1, then 83,3 in cycle 2, and 87,1 in cycle III. The completeness of classical study started from 53,8% in cycle 1, grew to 57,5% in cycle II, then reached 88,5% in the last cycle.
