This paper reviews its-research progress on diagnosis of agricultural products, water diagnosis, weed identification,product quality testing and grading, agricultural picking and sorting and other as- pects, and finally put forward its existing problems and prospects for the future.展开更多

As one of the primary expressing media and an important support when forming concepts, visual art plays an indispensable role in the pre-school period. The following thesis is based on an action research whose key tendencies were focused on establishing children＇s interests in different useful materials and tools while enabling them an autonomous visual art use of these tools and didactical possibilities of the teacher involved. The activities included in the research were fully in line with the Slovenian National Kindergarten Curriculum and the project was carried out in the form of several successive meetings intended for visual art creative activities. All activities in the research were photo-documented while the analysis of the research＇s data was performed based on observation and written notes referring to individual child＇s responses, his or her questions, ideas, and incentives, the course of cognitive and creative process, communication with the peers and teachers and other potential particularities.展开更多

Visual and audio, this two kinds of vocabulary brought out the best in each other with the support of multimedia and digital audio technology, and also formed a new audio-visual language. The original ecological of percussion, multimedia image and interactive technologies impacted the natural and avant-garde. It is the possibility that this practice provides new form in the spread of Chinese culture.展开更多
