《算法与程序设计》是高中信息技术课程的选修一模块。根据课程标准的要求,这个模块的学习目的是使学生在原有基础上进一步体验算法思想,了解算法和程序设计在解决问题过程中的地位和作用;能从简单问题出发,设计解决问题的算法,并能初步使用一种程序设计语言编写程序实现算法解决问题。在多年教学实践中,经常可以发现这样的情况,学生能听懂教师讲解的程序设计例题,也能看懂一些简单的源程序,但如果独自完成程序设计题目却往往不知如何下手。我认为从VB可视化和中学生接受能力强的特点入手,可以更好地培养学生的程序设计能力。
“Algorithm and Programming” is an elective module for high school information technology courses. According to the requirements of the curriculum standards, the purpose of this module is to enable students to further experience algorithmic thinking on the basis of the original, understand the status and role of algorithms and program design in the process of solving problems, and design algorithms to solve problems based on simple problems. And can initially use a programming language to write programs to implement algorithms to solve problems. In many years of teaching practice, such situations can often be found. Students can understand the programming examples given by the teacher, and can also read some simple source programs. However, they often do not know how to start if they complete the programming topic alone. I think that starting from the characteristics of VB visualization and high secondary school students’ ability to accept, we can better develop students’ programming skills.
