【摘要】 信息技术的飞速发展,推动了教育的目标、模式、形式、内容的全面改革。我国2017年颁布的高中信息技术新课程标准明确指出,要将培养学生的核心素养作为教学任务和根本目的。计算思维作为信息技术学科四大核心素养之一,不仅对于其他的核心素养有相辅相成的作用,与学生创新能力的培养,问题解决能力的提高也有密切关系。本研究以计算思维的研究现状为出发点,以活动理论为基础,探索以培养高中生计算思维为核心目标的信息技术课程教学模式。具体开展了以下研究:(1)阐述了计算思维的概念及特性,介绍了本研究所涉及到的理论。(2)分析了2017年高中信息技术新课程标准和高中生现阶段思维能力的表现,总结了培养计算思维的信息技术课程教学原则,在此基础上构建了以培养高中生计算思维为核心目标的信息技术课程教学模式——基于活动理论的以教师与学生“双主线”为主体的新型教学模式。从创设情景,整合信息、模型构建,问题求解、问题解决,优化方案、评价反思,迁移应用等四个部分详细阐述了本研究所构建的新型教学模式。(3)选择了高中信息技术课程中算法内容为教学实践内容,以本研究所构建的信息技术课程教学模式为指导设计了教学案例,使该教学模式在高中信息技术教学实践中得以运用,对该教学模式的教学实施效果进行了评估。通过教学实验得出以下结论:本研究所构建的信息技术课程教学模式在具体的课堂教学活动中提升了学生解决实际问题的能力,学生对该教学模式有了深刻的认识,能够体会该教学模式给他们带来的思维上的转变。在教学实践的过程中学生思维方面的能力也得到了提升。更多还原

【Abstract】 The rapid development of information technology has promoted the comprehensive reform of the goal,mode,form and content of education.The new curriculum standard of Information technology for senior high schools issued in 2017 clearly states that cultivating students’ core literacy should be regarded as the teaching task and fundamental purpose.As one of the four core qualities of information technology,computational thinking not only plays a complementary role in other core qualities,but also has a close relationship with the cultivation of students’ innovative ability and the improvement of their problem-solving ability.Based on the research status of computational thinking and activity theory,this study explores the teaching mode of information technology curriculum with the core goal of cultivating high school students’ computational thinking.The following researches are carried out :(1)the concept and characteristics of computational thinking are elaborated,and the theories involved in this study are introduced.(2)analysis of the high school information technology new curriculum standard and 2017 high school students thinking ability of the current performance,summarizes the develop computational thinking information technology course teaching principle,on the basis of the constructed in terms of cultivating high school students thinking as the core target of information technology course teaching mode,with teachers and students based on the theory of the activity "double line" as the main body of new teaching mode.This paper expounds the new teaching mode constructed by this research in detail from four parts: setting up the scene,integrating the information,constructing the model,solving the problem,solving the problem,optimizing the scheme,evaluating the reflection and transferring the application.(3)The algorithm content in senior high school information technology courses is selected as the teaching practice content,and the teaching case is designed under the guidance of the information technology course teaching mode constructed in this research,so that this teaching mode can be applied in senior high school information technology teaching practice,and the teaching implementation effect of this teaching mode is evaluated.Through teaching experiments,the following conclusions can be drawn: The information technology course teaching model constructed in this research improves students’ ability to solve practical problems in specific classroom teaching activities.Students have a profound understanding of this teaching model and can experience the change in thinking brought by this teaching model.In the process of teaching practice,students’ thinking ability has also been improved.更多还原
