化学教学中,化学实验起着十分重要的作用。尤其在新课程标准背景下的化学实验更注重学生的探究、主体地位。因此,积极创设条件,自制代用品,引进微型化学实验;选择性进行实验,精心设计,精密组织,客观评价,才能让化学实验教学更高效。 Chemistry teaching, chemical experiments play a very important role. Especially in the context of the new curriculum standard chemistry experiments pay more attention to students’ inquiry, the dominant position. Therefore, we should actively create the conditions for self-made substitutes and introduce mini-chemical experiments; and selectively conduct experiments, elaborate designs, sophisticated organizations and objective evaluations in order to make chemical experimental teaching more efficient.
