In this research, the teaching processes of Turkish language and literature, language-expression, mathematics, geometry, physics, accounting in companies, office programs in computers, legal services, legal secretariat, entrepreneurship and business management courses are described. The study, which describes the teaching-learning process of general and vocational courses, was carried out with a "cumulative case" study for 3 years and 5 terms. In the research, the annual plans of 24 teachers were examined and the lessons of these teachers were observed by 94 teacher candidates for 993 lesson hours. With the content analysis of the teachers' annual plans and the written observations of the teacher candidates, the themes of "teaching method-technique", "teaching tools" and "assessment tools" emerged. Teachers included teaching methods such as lecturing, question-answer, commentary, case study, problem solving and demonstration in their annual plans. In the classroom observations, it was determined that the teachers mostly used lecturing, testing, question-answer, and dictation methods in their lessons. In annual plans, course tools such as course book, presentation, tests, Eba materials, dictionary and spelling guide, concept maps and magazines were written. However, it was determined that the teachers used textbooks, tests and slides in their lessons, and it was observed that some of them did not use any materials. It has been revealed that teachers also use assessment tools such as multiple-choice and short-answer tests, written exams, and mixed exams in their teaching, which they specify in their annual plans. Although the years and students have changed, it has been revealed that the teachers use similar annual plans, teaching methods, teaching materials and assessment tools in their lessons. In addition, it has been determined that teachers who teach different courses in different schools with different students, use similar annual plans, teaching methods, lesson design and assessment tools in the teaching-learning process of their lessons.
