基于App Inventor和计算思维的信息技术课堂教学研究

Instructional Research of Information Technology Based on App Inventor and Computational Thinking

中小学信息技术课程是培养中小学生计算思维思想的有效途径。目前相当数量的中小学校在信息技术教育的教学内容和教学方法等方面存在知识点古板、教学设计不符合中小学生认知规律等无益于中小学生计算思维培养的问题。App Inventor是采用模块拼接方式快速开发移动应用的设计工具，可以培养中小学生的计算思维能力。综合计算思维和App Inventor的特点，针对目前中小学信息技术课程教学现状，该文探索提出了以教师为设计者、组织者、引导者，以App Inventor为学习工具，通过师生合作、生生合作等形式，学生主动利用计算思维思想解决问题，来培养计算思维能力的学习模型。通过实例论证，该模型可以有效提高学习和教学效率，培养学习者的计算思维能力，同时为教学者的实际教学提供了参考。

Information Technology Course of primary and middle school is an effective way to develop the capability of schoolchildren on computational thinking.At present， a considerable number of primary and secondary schools have some problems on teaching contents and teaching methods of information technology education，which are no use to train the capability of schoolchildren on computational thinking.App Inventor is a design tool，which programs by splicing module，and it can cultivate the computational thinking ability of the students.Synthesizing the characters of App Inventor and Computational Thinking，for the current situation of information technology course teaching，this paper explore the study model of information technology course. In the model，teachers are made designers， organizers， guide， and students take the initiative to solve problems using computational thinking thoughts to train the capability of schoolchildren on computational thinking with App Inventor through cooperation between teachers and students， students and students.Through the demonstration of the case，we get that the model could not only increase the teaching and study efficiency but also improve the learner's computational thinking ability. Also the case gives a reference to the educators on cultivating the computational thinking ability.
