进行实验,实验者必须熟练地掌握操作技能,才能顺利地进行实验,做到不断创新进而改造实验,推动科学技术的发展,以适应四化建设的需要。美国的教育学家布鲁姆把技能操作领域大致分为:领悟、接触、模仿、操作、熟悉、创作六个水平层次。在基础教育中,如何培养学生的实验操作技能,笔者结合我地两次初中化学实验操作竞赛所得到的启示,谈谈自己肤浅的看法。第一次竞赛:是由地区教研室命题,县教研室组织进行的化学知识的初赛和复赛后,在全县近六千名学生中选出成绩优秀的二十四名参加县教研室举行的初中化学实验操作竞赛。赛题内容是:选用所给仪器和药
To carry out experiments, the experimenter must master the operation skills and skillfully, so as to carry out the experiment smoothly, to innovate continuously and reform the experiment, and to promote the development of science and technology to meet the needs of the four modernizations. American educationist Broome divides the areas of skill operation into roughly six levels: comprehension, contact, imitation, operation, familiarity, and creation. In the basic education, how to cultivate students’ experimental skills, the author combines my two junior high school chemistry experimental operation competition to get the inspiration, talk about their superficial views. The first competition: After the preliminaries and the semi-finals of the chemical knowledge organized by the county teaching and research section, the county’s teaching and research section organized a junior high school chemical experiment in the county’s teaching and research section. Among the nearly 6,000 students in the county, 24 were selected. Operation competition. The content of the competition is: use the given instruments and medicines
