Teaching practice of the course of Laser Principle and Application based on PBL mode

Abstract

Abstract.The primary task of university education is to stimulate students' autonomic learning and cultivate students' creative thinking. This paper put to use problem based learning (PBL) teaching mode, to enable students master flexible knowledge as the goal, and a detailed analysis of the implementation method and concrete measures of PBL teaching reform in the course of Laser Principle and Application, then compared with the former teaching methods. From the feedback of students and teaching experience, we get good teaching effect and prove the feasibility of PBL teaching mode in Since the 20th century, the laser is another major invention following the atomic energy, computer, semiconductor of mankind. As soon as it appeared, the world changed a lot, it has been widely used in the military, aerospace, communications, industry, medicine, scientific research, etc.1-5 Science and technology is the first productivity, and laser technology is one of the important component. Therefore, it's particularly important to learn the course of Laser Principle and Application, as a teacher, we should to introduce advanced laser principles and acknowledges, and professional laser technology to students. However, due to the difficulty of the course content, it is hard for the students to master the teaching content required by the

Transdisciplinary STEM education based on Among’s philosophy implementation against engineering problem-solving and motivation: The case monochromatic light, simple laser project

“…Laser teaching is essential because it is technologylinked, authentic and relevant to the real world, and related to interdisciplinary science (Clark et al, 2019;Jaime et al, 2016;Li et al, 2017;Prinsloo & Deventer, 2017;Wengrowicz et al, 2017). Several universities in China, Taiwan, and the United States have used PBL to teach laser and optics materials to improve students' design skills, knowledge management skills, confidence, and professionalism for the future (Bilgin et al, 2015;Clark et al, 2020;Tsybulsky & Muchnik-Rozanov, 2019).…”
