摘要
探索一种全新的通过计算科学地选购录播系统的方法,使录播系统适应教师授课风格,从而达到提高教学质量和办学效益的目的。经由大量观察、分析、研究教师的授课风格,将其归纳为定位、简单移动、综合移动、板书、交互和演示6种类型,探索出教师授课风格的量化方法。同时,通过对录播系统特点的分析,也将其分为单机、半自动、全自动和传统的4种录播系统,并研究了各系统的特点。然后,对录播系统和授课风格进行关联,找出内在规律并分析了确定录播系统数量的其他因素。最后,导出基于授课风格的各类录播系统需求量的计算式。利用该式的简单计算,可以确定一所学校各种类型录播系统的需求量。
This paper explored brand-new methods for scientifically selecting recording and broadcasting systems through the computer so that the selected system can suit the teacher＇ s instructional style, thereby improving teaching quality and educational results. After extensive observation, analysis and research, teaehers＇ instructional styles are classified as six types： positioning, simple movement, integrated improvement, board writing, interaction, and demonstration. And the recording and broadcasting systems are classified into single-machine operation, semi-automatic, fully automatic, and conventional. The characteristics of all systems are then studied and the correlation between recording and broadcasting systems and instructional styles are studied to identify intrinsic patterns and to pinpoint other factors deter- mining the quantity of recording and broadcasting systems. The ealculation formula for determining the quantity of all types of recording and broadcasting system required is eventually derived. Using this formula for simple calculations, quantity of all types of recording and broadcasting systems required by a school can be determined.
