认真品读《探索三角形全等的条件(第一课时)》课例(四)(湘教版),感觉徐老师熟练地运用教育理论驾驭课堂教学,体现了新的课程标准的基本理念,该课例是一堂建构主义观下的数学课.建构主义认为:知识不是通过教师传授得到的,而是学习者在一定的情境下,借助学习获取知识的过程中其他人(教师或同伴)的帮助,利用必要的学习资料,通过意义建构的方式而获得.由于学习是在一定的情境下,借助别人的帮助即通过一定的人际间的协作活动而实现意义建构过程的.因此建构主义学习理论认为“情境”、“协作”、“会话”、“意义建构”是学习环境中的四大要素.如果我们的数学课堂能够正确地把
Seriously reading “the conditions for exploring triangle congruence (first class hour)” lesson (4) (Xiangjian edition), I feel that Professor Xu proficiently uses the theory of education to control class teaching and embodies the basic concepts of the new curriculum standard. The case study is a mathematics lesson under the concept of constructivism. Constructivism holds that knowledge is not obtained from teachers, but rather from the help of other people (teachers or companions) in learning to acquire knowledge under certain circumstances, The use of the necessary learning materials, obtained through the way of meaning construction.Because learning is in certain circumstances, with the help of others, that is, through a certain interpersonal collaboration activities to achieve the meaning of the construction process.Therefore, constructivist learning theory that “Context ”, “Collaboration ”, “Session ”, “Meaning Construction ” are the four elements of the learning environment.If our math class can correctly
