在初中化学实验教学中,针对教材实际,充分利用自制的化学仪器投影模型片,不仅扩大了实验观察面,增大信息量,而且为学生提供模拟实验操作的机会,强化了实验教学内容。下面谈谈投影模型片的制作及在初中化学实验教学中的运用。 In the junior high school chemistry experiment teaching, according to the actual teaching materials, full use of self-made chemical instrument projection model, not only expanded the experimental observation surface, increased the amount of information, but also provided students with the opportunity to simulate experimental operations, and strengthened the experimental teaching content. Here to talk about the production of projection model and the use of junior high school chemistry experiment teaching.
