| The sight singing and ear-training practice is the basis of the objectives of professional music lessons which aim at systematically developing the music hearing ability. Teaching for the content of the training elements of music involves the singing, playing, listening, writing, reading or practicing a variety of comprehensive means to make acquisition and consolidation. Practice plays an important part in the logical sequence of entire teaching. Therefore, this paper is to take the sight singing and ear-training practice as a study subject and to take the two-stage practise design as a study content which includes the "earlier period preparation" and "following practice". Among them, the author introduced the "intention teaching" blonging to the education-psychology into the disciplines in attempt to making it as the theoretical basis for research, which the author want to grasp the design of the direction of teaching practice from the macro level, meanwhile, in order to fully achieve the course objectives.In the teaching activities, the "intention teaching" requiring teachers to design the teaching plans in the perspective of education-psychology and judge and solve problems. Based on the points mentioned above, the teacher should emphasized the classroom practice so as to hold the overall content and plan the teaching major points and difficulties in accordance with the teaching subject .In the "earlier period preparation", the teacher should highlight the use of practice theory of motivation and the practice participation as well as the fun function. At the same time, the teacher also should abide by the laws of cognitive development and explore the diverse-means of music perception. In the "following practices", the ability to design application-oriented training exercises should be the main step which put emphasis of the migration of music training, such as the use of improvisation, adaptation, to enhance the knowledge content. On basis of the traditional teaching model, the teacher should consider the practice plan as the important point that emphasize the cooperative learning in which the panel discussion and the cooperative creation as the main means.Doing this research of two-stage study can guide us, on the one hand, to pay attention to the music learning process, in particular, to focus on the two-stage teaching phenomenon-music penetration and the extension, in order to further explore the cognitive development of the law of the hearing. On the other hand, according to the "intention teaching", this research can help us to think about the teaching activities positively and actively, to adjust the teaching plans, to use a variety of teaching models, teaching methods as to enrich the classroom's cognitive means, and to achieve the ultimate goal of improving teaching. |
