Project Approach in the keying of technical teaching

Paper Keywords: Project Approach in the body axis as the technology resourceful teaching methods of teaching
Abstract: The project is a project-centered teaching, students under the guidance of teachers, methods of learning activities; project teaching to students of "exploratory" learning for the purpose. This paper describes the concept of the project related to teaching, and then detailed explanation of the project as the technology hub of teaching in the teaching, the last item on the fans multimedia software teaching method in practical applications.

Vocational and Technical College is to train high-quality specialized technical talent base, shoulder to specific industries and job training of qualified skilled personnel operating the mission. Modern society requires the ability of people have four aspects: social adjustment, general industry, professional core and job-specific skills. use of project implementation organization of teaching approach to suit the ability of students and methods of enhancing social capabilities.

Keying technique is commonly used in video editing special effects. "Keying" is drawing a picture in a color as transparent color to pull it from the screen to go, so revealing the background to form the superposition of three synthetic images. This After shooting the people in the room with a variety of scenery after keying superimposed together to form the Art of magic effects. how keying technology in the teaching process can enable students to master the required knowledge and skills and allows students to gain a strong learning, thinking skills, creative ability, practical ability and other integrated capabilities, which requires teachers in the teaching practice continuing to explore and summary. Here with my teaching practice, teaching of project applications in keying technology.

1 Project Approach
Project Approach is jointly implemented by teachers and students a complete project work and teaching activity, both as a curriculum model, but also a teaching method. Therefore, the project approach in the use of instructional design, the students are recognized knowledge of the subject, is active constructors of knowledge and meaning. subject to the following four principles:
1.1 The student-centered, play a facilitating role of teachers
In the teaching process, students should give full play to the initiative and innovative spirit, so that students act according to their own self-feedback Information; also can not ignore the guidance of teachers, students directly involved in the project made the whole process.

1.2 Project selection is the key
Select the project to the teaching content based on both ability to include basic teaching points, but also to mobilize the enthusiasm of students to solve problems. Teachers and students to pArticipate in the selection of the project, select the difficulty for the project.

1.3 The creation of learning resources and collaborative learning environment is the most important work of teachers
Teachers need to provide students with multiple opportunities in different scenarios apply the knowledge, full use of modern educational technologies to provide students with a variety of learning resources.

1.4 The case of the student to complete the project to evaluate the learning
The ultimate goal of the learning process is to complete the construction of meaning, rather than teaching objectives. Teaching is not about teaching goals, but around the completion of the project design to achieve the construction of meaning to expand, so the evaluation of student learning situation should be assessed in order to complete the project .

2 Project Approach in keying technology teaching
Keying technology to some extent the students for the computer multimedia technology provides a technology to create multimedia works and means of teaching technology in the teaching method used in the project, can make students more focused and practical, to develop students practical ability, analytical skills, comprehensive ability, adaptability, communication skills, ability to cooperate and to solve practical problems.


2.1 The project goals, stimulate interest in learning
Keying technology is the actual filming and post-production, a combination of technology work to have a good keying: theme of the clear and unequivocal, innovative ideas; the contents well, and completely expresses the theme, with a strong ornamental; able to accurately, the right use of technology, harmonious and smooth movement throughout the work.

Instance keying technology-based projects, such as explosions, fire and air flight and so on. Implementing curriculum, teachers will be ahead of the video shoot with a blue background material to students, for students to practice the production of a variety of color key method, and layout of the project, the students see the project objectives, group discussions, so that their attention will be focused on real shot in the material preparation and post-production. reposted elsewhere in the Research Papers Download http://www.hi138. com 2.2 project preparation, preparation of teaching and learning
Clear objectives, it is necessary for project preparation, this preparation includes the preparation of teachers and students. Teachers: preparing teachers for students the first keying a successful case, to provide students with a template produced by the project for reference. For example, students do pull As before, teachers, keying by a successful case, explain the basic process of keying made, on this basis, from the blue / green back shot - keying production - post production and other aspects of a detailed explanation, and the production process may problems and issues between the need to pay attention to explain. Meanwhile, the students limited to a range of topics. students: the choice made by each group of students interested in the project based on the theme, subject search for Articles, images, data and other's creativity, pave the way for future operations, and write detailed project production program.

2.3 Through implementation of the project to stimulate students creativity
Project is that students will make the program into the work process. In keying, involving a lot of relevant theoretical knowledge, such as the color key, layer, channel editing, etc.; also choose what kind of keying material, and through what way to show themes. These are the students need to be organized to discuss. During the discussion, students can contribute their books, network, or other sources of Information, finally arrive at a design or more effective experimental program and based on the implementation of the division of labor to complete the project. in the production process, but also through mutual discussion, the knowledge of their relatively weak link in the enhancement supplement. to answer the teacher's role is to keep students in the production process problems and errors in operation for students to correct me. Special attention is, teachers should always be encouraged for students so that they remain confident in the face of difficulties.

2.4 Project Review and Evaluation
Results of the work to be carried out in accordance with the intended target to self-and mutual inspection, evaluation to achieve the results. This process our students a sense of responsibility, quality awareness and assessment methods. As a teacher, is responsible for the design and organization of the teaching, the students directly involved in the discussion . usually observe the implementation of the project in each group and found that discussion with students to solve problems in a timely manner. the work of each group self-assessment first, and then evaluated by other groups to each other. students to complete the work of assessment, teachers complete the final assessment. sinks in the project, you can also experts invited to pArticipate in the company of the process of evaluating student work. students can learn more skills in performing, fully absorb the essence of the project activities. Through the study of evaluation, teacher for a number of difficult problems in a more thorough understanding of, and has accumulated more Multi-project of teaching experience.

3 Project Approach in the practical teaching of multimedia software applications
In addition to keying in the implementation of the project technology teaching pedagogy, teaching of video effects of teaching when the teaching use of project implementation, teaching certification program through the teaching practice can be applied to multimedia software teaching. By building into a small project to complete These small projects, to acquire knowledge and skills of the purpose of points. For example: Teaching in After Effects to create video effects as the main content of the course, just begun, in the absence of any relevant knowledge of teaching the case, let the students material according to their teachers try to make a video work. After a burst of exploration and practice and interactive discussion among students, few students have a higher perception to be completed. these students to other students and can guide the operation, and then summarize and teach teachers operation of the key steps.
