化学是一门以实验为基础的自然科学,化学实验是学生学习中能动的实验活动形式。为学生创设亲自参与实践的情景具有帮助学生获取知识、激发兴趣、追求真理,严肃认真的科学态度等教育功能,能使学生体验和了解科学探究的过程方法,形成和提高创新意识,树立科学的价值观。但传统的化学教材安排实验大都是验证性的,对实验的理论、背景和操作设计不予重视,往往重知识轻方法,重结果轻过程,重接受轻参与,不利于学生创新能力的培养。为此作者建议在教学中宜采取以下措施来加强学生的动手能力,激发学生的好奇心,求知欲,发展学生的思维:
Chemistry is a natural science based on experiment. Chemistry experiment is a form of experimental experiment that students can learn. Creating situations for students to engage in hands-on exercises Educational functions such as helping students gain knowledge, motivating, pursuing truth, and serious scientific attitudes, enabling students to experience and understand the process and methods of scientific inquiry, forming and raising awareness of innovation, and establishing a scientific Values. However, most of the traditional chemistry teaching materials arrangement experiments are mostly confirmatory. They neglect the experimental theory, background and operation design. They often emphasize knowledge and method of light, re-emphasize light process and re-accept light participation, which is not conducive to the cultivation of students’ innovative abilities. To this end, the author suggests that the following measures should be taken in teaching to enhance students’ practical ability, to stimulate students’ curiosity, curiosity and development of students’ thinking:
