| In recent years, with the development of the computational subject,computational thinking gradually become an important concept that the current international computational world widely attention to.how to develop the students’ ability of computational thinking better has become a top priority task. A mass of research and experiment proves that the programing design course embodies the cultivation of creative thinking process, complete program design, covering the critical reading, tool use, abstract expression skills, comprehensive creation, etc So in the cultivation of the computational thinking in the program design course and the program design course reform and the practice is of great significance.But at present, in the teaching of programming language, more educators are partial to teach the interpretation of language knowledge, students struggle with details such as the statement, grammar rules of program design itself. The whole teaching effect cannot be improved. Due to too much emphasis on curriculum knowledge content module, largely ignored the learners to calculate the cultivation of computationl thinking ability. Aiming at the situation, based on App Inventor of higher vocational school students calculation mode of computional thinking, providing a reference for the teaching of higher vocational schoolsThis thesis consists of six chapters:The first chapter is introduction. Mainly introduced this topic research background and research status at home and abroad, as well as the research significance, research contents, research methods, research results and research idea do important interpretation。The second chapter is the research basis.This research topic in the use of defining the relevant theoretical basis.The third chapter introduces the App Inventor and computational thinking.In practical application and literature reading, on the basis of studying the characteristics of App Inventor with related computational thinking of the concept, for the back of the case design provides the theoretical foundation and model building.The fourth chapter research analysis phase.The object of the present study for vocational school students, the author through the way of online research and a questionnaire on the spot in sichuan city vocational schools, vocational college of sichuan normal university, sichuan institute of technology of profession of electronic machinery, zhengzhou business technician institute and so on four higher vocational school students respectively from learners thinking ability training situation, the higher vocational school students calculation thinking ability, higher vocational school students understanding of computational thinking and to use situation and so on three aspects has carried on the investigation and analysis.The fifth chapter is to build and present the specific cases.This section based on the related theoretical basis to build computing thinking cultivation model for higher vocational students based on App Invenrtor, and presents the Small program micro teaching design problem test, Text applet micro teaching design, Add multiple consecutive integers micro program teaching design. a total of three teaching cases.The Sixth Chapter is the study part about the model. Through the design method of the experimental group and the control group, In the experimental group using constructed teaching practice teaching mode, After teaching practice, According to the experimental group and control group respectively design specific tasks Search the related data from interviews were analyzed by constructing the teaching model for students to use computational thinking method to solve the problem of other areas are valid.The seventh chapter is summarized and prospected.Summed up in the work of some of the important research topics and main results, review the whole process of research and innovation of the paper, reflection of the insufficiency in the research, the writer put forward to improve work and further research direction. |
