| Engineering thinking is a higher-order thinking for design and planning.In the context of the increasingly engineering-oriented era,strengthening the cultivation of primary school students’ engineering thinking ability plays an important role in promoting students to form a habitual way of thinking to solve problems and even lifelong development.At present,the cultivation of engineering thinking has risen to the level of primary school science discipline construction and national strategy.However,the foundation of engineering education for basic education stage in China is relatively weak,and the cultivation of engineering thinking for primary school science lacks a special and effective teaching model,which needs further research.First of all,based on the background of the times,this thesis combed the domestic and foreign literatures on engineering thinking,teaching mode,and science education,and focuses on extracting the content related to the teaching concept of this research.After that,this thesis studied and compared the "Primary school science curriculum standard for Compulsory Education" and the CDIO syllabus to understand the domestic expectations for primary school science courses and the international training direction for engineering talents,so as to provide a target basis for the construction of the teaching model.The core part of this thesis is to construct a goal-oriented engineering thinking training model--QDII teaching model based on the concept of OBE achievement-oriented education model and CDIO engineering education model,and to define the framework of lesson preparation for science teachers and the stage of engineering activities adapted to the cognitive characteristics of primary school students.Finally,according to the concept of advanced learning,this thesis selected students from the lower,middle and higher grades to conduct comparative practice research,to test the feasibility and effectiveness of QDII teaching mode,and constantly improve the teaching mode in the cycle of practice and improvement.Through practice,QDII teaching mode has a practical and feasible effect on cultivating primary school students’ engineering thinking ability.The model can take the student as the center,stimulate students interest and curiosity to drive to complete project activities,and stimulate students multidimensional thinking in the activity,exercise the students’ ability of tool use,make students form in repeated trial and error and reflection engineering reasoning habits,enhance students’ willpower in the setback,ultimately achieve the goal of comprehensive reinforcement engineering thinking ability.At the same time,the QDII teaching model can provide front-line educators with clearer teaching design ideas and classroom implementation processes,provide teaching guidance for the cultivation of engineering thinking in primary schools,and provide ideas for other scholars to explore the cultivation of engineering thinking ability. |
