传统的以大考为主的评价体系难以承担全面反映中职生学习成果的重任。因此,应建立一套能反映中职生学习能力,并帮助他们提高学习积极性、主动性的评价机制,贯穿于化学学习的各环节,最终达到让教师有的放矢、让中职生循序渐进地掌握化学知识的教学目的。 The traditional evaluation system based on the college entrance examination is difficult to fully reflect the important task of secondary vocational students learning. Therefore, we should establish a set of evaluation system that reflects the learning ability of secondary vocational students and help them improve their learning initiative and motivation. Throughout all aspects of chemistry learning, teachers should be targeted in the end so that secondary vocational students can grasp the chemical knowledge step by step The purpose of teaching.
