学术导向的图像处理课程教学改革
|
摘要
针对目前图像处理课程在授课过程中存在的教学内容陈旧、轻实践、理论难度大和缺乏创新能力培养等方面的问题,该文坚持"科研服务教学,教学促进科研"学术导向的理念,从教学内容、教学实验、教学方法和考核四个方面对该课程进行了全面的教学改革。为检验此次教学改革的成效,对中国矿业大学"图像处理"全校公共选修课程近三年的学生选课人数、出勤率和成绩的情况进行了对比分析。教学改革实践表明,其有效地解决了在授课过程中存在的上述问题,明显地提升了教学质量。
There are some problems in the course of teaching "Image Processing",such as the old teaching content,the light practice,the difficulty of the theory and the lack of innovation ability. Therefore,this paper insists on the academic-oriented conception of "scientific research serving teaching,teaching promoting scientific research". The teaching reform has been carried out in a comprehensive way from teaching content,teaching experiment,teaching method and examination. In order to test the effectiveness of the teaching reform,the number of students,the attendance rate and the results of the students' elective course in the public elective course of the "image processing" of the China University of Mining and Technology in the last three years were compared and analyzed. The practice of teaching reform shows that it effectively solves the above problems in the teaching process,and significantly improves the quality of teaching.
