Research On Harmonious Achievement Of Three-Dimensional Teaching Goal In Middle School Physics Teaching Design

By use of modern education and teaching theory,combining the contents of physics teaching in middle school and the students' psychological characteristics closely,and centering on the cultivation of middle school students' core competencies,and focusing on the harmonious achievement of three-dimensional teaching aim,we have carried out a series of research on teaching design about middle school physics,the main contents are as follows:(1)We have summarized the four basic learning theories: behaviorism,link-cognitivism,constructivism and humanism,and discussing the characteristics of middle school physics teaching design based on each learning theory.(2)We have discussed the goal and the basic principles that should be followed by middle school physics teaching design.The goal is to achieve the three dimensions of "knowledge and skill","process and method","emotion attitude and values' in harmony,pointing out that the middle school physics teaching design should follow six basic principles,which are to guide students to understand physical knowledge,to help students to master scientific methods,to develop students' practical ability and innovation ability,to stimulate and maintain students' learning interest and thirst for knowledge,to promote students to form scientific attitude and scientific spirit,and to induce students to develop the necessary character to adapt the lifelong development and social development.(3)Focusing on the contents of middle school physics teaching design and the students' psychological characteristics,we have designed three teaching cases with excellent teaching effect according to the requirement of harmonious achievement of three-dimensional teaching goal,and developed a series of physics experiment and local physics curriculum resources which are popular with students.The first case is the teaching design of "understanding buoyancy".Considering the middle school students' age characteristics,we have constructed a series of interesting practical experience activities to guide students to experience buoyancy,to know buoyancy and to apply buoyancy,and paid attention to improve students' core competencies in this process.The second case is the teaching design of "Sound generation and dissemination".We have designed a series of interesting experiments and questions to cultivate the students' learning interest and creative ability in the process of observing the experiment and solving the problems,and made the students ' psychological quality and physical knowledge to achieve synchronous development.The third case is the teaching design of "overweight and weightlessness".We have used a series of interesting activities to guide students to experience and cooperate,to construct and understand the knowledge of "overweight and weightlessness",and also focused on the teaching process to cultivate students interest and improve the core competencies.Our innovative work is that have designed three excellent teaching cases,developing a series of physical experiment and local physics curriculum resources which has got the students' approval.The corresponding research results have been published in the National Physics teaching professional journals,which also have been widely used in the physics classroom and have got unanimously praise.
