전문계고 기계교과·현장실무 연계수업자료를 통한 기계수업 개선방법에 관한 연구

Abstract

The purpose of this study is to examine changes in students' perception of mechanical majors and learning attitudes by applying machine subject classes to high school seniors using materials linked to machine subjects and field practices. The purpose of this study is to first develop class materials linked to machine subjects and field practices, and then analyze data collected through questionnaires and interviews to confirm the effectiveness of the developed textbooks. To this end, the following research questions were set up.1) Develop mechanical subject and field practice-linked class materials that can be used in professional high school mechanical major classes.2) When applying the developed machine subject and field practice-linked class materials to actual classes, what is the change in students' perception of mechanical majors, such as interest and learning attitude? In order to solve Research Question 1, the direction and procedure of data development were established by referring to the papers of Kim Ki-yeon (2013) and Jeong Hye-jin (2014). In the process of developing data, machine subjects were selected with the help of current teachers, and related occupations were selected according to the selected machine subjects and class materials linked to machine subjects and field practices were developed by referring to related data and major books. In order to examine the validity of the data, the data was revised after being reviewed by two incumbent teachers, and the development of the data was completed after the final review under the guidance of the supervisor. After developing the materials, in order to apply the developed learning materials, one class for the third year of a vocational high school was selected and conducted. After the end of the class, the questionnaire presented to find out detailed characteristics such as students' mathematical beliefs and attitudes in the development of mathematics-related textbooks and application to classroom classes by Jeong Hye-jin (2014) was modified to suit the nature of this study to observe changes in students' perceptions before and after class. In addition, two students were selected and additional interviews were conducted based on questionnaire answers and used to derive research results based on answer data. The results of the experiment were collected through questionnaires and interview data. The answers through the questionnaire and interviews with two students were comprehensively reviewed and concluded. First, the class was conducted based on data related to the field practice of jobs related to machine subjects in the machine major, so that students could feel that it was a different class from the existing theory class and reduce the boredom of machine subject classes. Second, it was discovered that students could change their perception of machine majors by assuming the situation in the field practice of the actual job (company) and solving problems in the assumed situation using the machine subject theory learned in class. Third, by specifically introducing what kind of screening the job (company) is employed and what kind of screening is for professional high school mechanical students, students thought they could use the theory they learned in their future, and the reason for studying mechanical subjects became more clear. Overall, the necessity, interest, and learning attitude of mechanical majors changed positively through classes applying linked data, and there was no reason before that, but it was used as a data that could lead to a change in students' perception of mechanical majors, knowing how they are specifically used in their future fields and thinking that they should study mechanical majors to better perform their jobs in their future jobs.
