声乐重唱课程改革与实践——基于“研、演、赛、学”融合的“导图式”研究

多元文化教育是现代教育的热点话题之一,其既是一个新型的教育理念思潮,也是一项教育改革实践。多元文化是现代经济社会不断发展的产物,音乐教育是人类文明发展史上的重要组成部分。因此,如何基于多元文化融合背景,实现音乐教育创新是一门值得深思的课题。本文以声乐重唱课程为例,首先论述了声乐重唱课程的重要性,其次从“研、演、赛、学”四个方面探讨了“导图式”教育教学方法,最后从基础任务、进阶任务、核心任务、最终任务四个方面提出了声乐重唱课程改革与实践路径,意在提高教育教学效果,激发学生学习积极性和主动性,让学生在声乐重唱课程学习中拓宽眼界、提高精神内涵,提高自身文化修养。

Navigation Map Data Representation and Parallel Display Algorithm in an Embedded Environment

Map data display is the basic information representation mode under embedded real-time navigation. After a navigation display data set （NDIS_SET） with several dimensions and corresponding mathematical description formula are designed, a series of rules and algorithms are advanced to optimize embedded navigation data and promote data index and input efficiency. A new parallel display algorithm with navigation data named N PDIS is then presented to adapt to limited embedded resources of computation and memory after a normal navigation data display algorithm named NDIS and related problems are analyzed, N_PDIS can synchronously create two preparative bitmapa by two parallel threads and switch one of them to screen automatically. Compared with NDIS, the results show that N_PDIS is more effective in improving display efficiency.
