摘 要:层层递进式“按图索块”的教学模式是指在课堂教学中引导学生按照程序功能的不同层次规划不同等级的程序流程图,“按图索块”进行积木拼搭,层层递进,直至完善程序流程图,进而完成程序的整个设计,最后对整个流程图进行回顾,整体把握教学内容的过程。这种教学模式先细节后全貌、先局部后整体、先体会成功的快感再回顾成功的过程,符合技工教育的认知规律,因而能达到较好的教学效果,很好的培养学生的程序设计思维。

Abstract:Step by step “according to the diagram search block” teaching mode is to guide students to plan different levels of program flow chart according to different levels of program function in classroom teaching,“according to the diagram search block” to build building blocks,step by step,until the program flow chart is improved,and then complete the whole design of the program,and finally review the whole flow chart,overall grasp the process of teaching content. This kind of teaching mode starts with the details and then the whole picture,the parts and then the whole,the pleasure of success and then the process of success,in line with the cognitive law of technician education,so it can achieve better teaching effect and cultivate students’programming thinking.
Keywords:step by step;teaching mode of “according to the diagram search block”;APP Inventor;technician education
