2、，先给出“小猫拜访好朋友sb2”这个已布置好背景的半成品，在此基础上顺理成章地认识角色。认识并调整好“小猫”这个角色后，进一步引导学生对拜访路线进行规划，设置“小猫”通过“调整方向”、“移动”、“对话”等几个步骤完成拜访过程。最后，调整“事件”、“动作”等指令的顺序，完成脚本的编写。二、学情分析精品w o r d 学习资料可编辑资料-精心整理-欢迎下载-第 2 页，共 7 页文档编码:CN3N10U10P8U7 HY4E3I1M4Z10 ZX9B5Z6I4V7文档编码:CN3N10U10P8U7 HY4E3I1M4Z10 ZX9B5Z6I4V7文档编码:CN3N10U10P8U7 HY4E3
