小学科学的实验中,实验的过程和现象都要让全体学生看到,所以实验仪器要醒目,同时观察的对象要突出。我在教学中,主要从做大、涂色、垫高等方面突出实验仪器;从投影放大、水中加色、空气加烟、衬上背景、改进教具等方面突出观察对象,以此提高实验可见度。
Primary science experiments, the process and phenomena of the experiment should be seen by all students, so the experimental apparatus should be eye-catching, while observing the object to be highlighted. In my teaching, I mainly focused on experimental instruments in the fields of enlargement, coloring and matting. Highlighting the observation objects in terms of projection enlargement, color addition in the water, smoke on the air, backing on the background, and improvement of aids, etc., in order to improve the visibility of the experiment.
