一、开展“开放式自主化学实验”的基本设想 “化学是实验性的科学”,化学学习和发展的基点是“实验”,这是大家已有的共识。但传统上中学化学课本中的实验多为“验证型”的——为概念、理论以及元素的性质教学提供“实验证明”或“科学依据”,实验被异化为“照方抓药”之事。因而使人产生 First, carry out the basic assumption of “open and independent chemical experiment” “Chemistry is experimental science”, and the basic point of chemistry learning and development is “experiment”. This is a consensus that we all have. But traditionally, experiments in middle school chemistry textbooks are mostly “verification type” - providing “experimental proof” or “scientific evidence” for concept, theory and elemental teaching, and the experiment is alienated into “taking prescriptions according to prescriptions.” Thus producing people
