Even some teachers think that not using multimedia courseware in teaching is conservative, outdated and lack of innovative consciousness. Therefore, some teachers do not consider the actual needs of teaching content when preparing lessons, and should make great efforts to make multimedia courseware to enliven the classroom atmosphere and achieve good classroom results. This abuse of multimedia, dilution of texts, putting the cart before the horse, can not achieve the expected teaching purpose.
