Digital Case Database Construction and Case Teaching for the Course of Modern Testing Technology of Materials

Abstract

The course of modern testing technology of materials has the properties of strong comprehensive nature and practical characteristic. Case database construction and case teaching play significant roles in enhancing the teaching quality and effects of the course for teachers and students. Based on the methods and techniques for measuring materials, this course designs basic theoretical cases, enterprise production cases, laboratory ability verification project cases and cutting-edge cases of joint use technology, and introduces them into the classroom for implementation, and the related cases are collected to build the digital case database. On the one hand, based on the digital case database, the implementation of case teaching of this course overcomes the difficulty that the teaching content is relatively independent and the students are difficult to compare and analyze the similar methods and techniques for measuring materials, making the students’ theoretical foundation more solid. On the other hand, based on the digital case database, the case teaching makes a comprehensive analysis of practical problems in production practice, stimulates students’ creativity and interest, and encourages students to provide solutions for the development or improvement of testing means, thus improving the quality of courses and the effectiveness of education. According to the survey, more students were satisfied with case teaching for the course of modern testing technology of materials and their test scores had been significantly improved. Furthermore, the digital case database broaden the channels and ways for students to study the course, and help students realize the new learning mode of learning at any time, flexible learning and long-term learning.
