我国新课程改革把科学探究作为教育教学改革的突破口。在高中化学教学中,化学实验的探究作为其教学效率提升的一种重要的学习方式,对于学生科学素质的发展具有重要的推动作用。具体的科学实验常受到实验场地以及仪器等诸多因素的影响和限制,因此,让每个学生都能参与化学实验中成为实验探究的重要议题。一、铝的性质实验及其相关的改进研究将用砂纸打磨过的几段铝条分别放在四支试管中,然后向试管中分别添加浓硫酸、6 mol·L~(-1)盐酸、氢氧化
The New Curriculum Reform in Our Country Take Scientific Inquiry as a Breakthrough in the Reform of Education and Teaching. In high school chemistry teaching, the exploration of chemistry experiment, as an important way of learning to improve its teaching efficiency, plays an important role in promoting the development of students’ scientific quality. Specific scientific experiments are often influenced and limited by many factors, such as experimental sites and instruments. Therefore, it is an important topic for experiment exploration that every student can participate in chemical experiments. First, the nature of aluminum experiments and related improvements Research will be polished with aluminum sandpaper several sections were placed in four test tubes, and then added to the test tube were concentrated sulfuric acid, 6 mol·L -1 hydrochloric acid, Hydrogenation
