不插电计算机科学活动教学模型构建

Construction of Teaching Model of Unplugged Computer Science Activities

为了使一线教师更好地开展不插电计算机科学活动,提高学习者学习兴趣和动机,采用经典扎根理论研究方法对42个不插电计算机科学活动进行编码分析,从而构建不插电计算机科学教学模型。教学实践显示,教师在开展不插电计算机科学活动时应确立以计算机科学知识为主、多元能力为辅的教学目标,活动材料的准备既需贴近生活、容易获取,还应具备学习功能和游戏功能,在实施活动时以自身认知策略为主,而学生应主要以团队协作的形式开展活动。

In order to enable front-line teachers to better carry out unplugged computer science activities and improve learners’interest and motivation,42 unplugged computer science activities are coded and analyzed by the classical grounded theory research method,thus,the unplugged computer science teaching model is constructed.The teaching model shows that teachers should establish the teaching goal of computer science knowledge as the main part and multi-ability as the auxiliary part when carrying out computer science activities without electrical power,it should also have the learning function and the game function in the implementation of activities with the focus on specific cognitive strategies,the students should mainly carry out the activities in the form of team cooperation.
