关于程序设计中界面和代码的再认识——一节高中信息技术研究课引发的思考

高中信息技术课进行程序设计教学时,师生普遍存在重视代码而轻视程序界面设计的现象。造成这种现象的主要原因是:教师在学习阶段没有界面设计概念;工作后又没有相应的经历;而讲解程序设计语言的教程通常只针对该语言讲解界面的实现,也不强调界面设计的重要性。其实,程序的界面设计是独立于程序设计语言的。一个程序界面是否友好决定了程序的易用性。

A New Understanding on Interface and Code in Program Design ---Thoughts on One Research Lesson

It is a common phenomenon that teachers and students often attach more importance to code while neglect program interface design when they teach program design in senior high school tech—nology course. The main reasons for this phenomenon are as follows: firstly, teachers often have no idea about interface design in their previous learning stage and also no corresponding experience in work af—terwards. Secondly, Gourses on program design language usually target at the specific language that helps the realization of the interface, neglecting the importance of interface design. In fact, the program interface design is independent of program language, and whether a program interface is friendly or not determines the usability and convenience of a program.
