在新课程的理念下,我们注重学生学习兴趣的培养,让学生成为课堂的主人。然而,常常因为教学内容、教学方法、创作手段等方面的瓶颈,学生难以成为课堂的主人。本文从学生喜爱的MIDI选修课引发思考,发现电脑音乐能够为学生提供音乐实践的自由空间、提高学生的创造表现能力,借此摸索出一些音乐创造表现教学的有效方法。 Under the concept of the new curriculum, we pay attention to the cultivation of students’ interest in learning so that students can become the masters of the classroom. However, it is often difficult for students to become masters of the classroom because of bottlenecks in teaching content, teaching methods, and creative means. This essay draws lessons from students ’favorite MIDI elective courses and finds that computer music can provide students free space for music practice and enhance students’ ability to create and express, so as to explore some effective ways to create performance teaching through music.
