Third-Order Upwind Schemes for Convection Equations

Aim To construct a third order upwind scheme for convection equation. Methods Upwind Lagrange interpolation was used. Results and Conclusion The schemes L p stability for p∈ is proved. Numerical examples show that performance of the third order upwind scheme is better than that of most second order schemes.

THE EFFECT OF TBLT METHODOLOGY ON STUDENTS' ORAL PERFORMANCE IN THE PRIMARY SETTINGS IN GUANGDONG

本文运用对比实验的方式,比较了任务型教学方式与三P教学方式在小学高年级学生英语口语能力发展中所起到的作用。在研究中,实验组实施的是任务型教学途径,而控制组采用的是三P教学方式。经过一个学期的实验研究,最后通过被试完成两个任务的测试成绩,分析了两种不同的教学方式对小学高年级学生在口语的准确性、流利性和复杂性三个方面的实施效果。作者得出结论:任务型教学方式优于三P教学方式。
