news playback Recently, the reporter learned from the Digital Experiment Teaching Forum sponsored by the Shanghai Experimental School of Primary and Secondary Digitalization that although digital experiments have made progress in promoting new curriculum reform and changing students' learning styles and teacher innovation experiments, It is precisely the experiment that many of our physical teachers are the most unprofessional wine course in hk. Phenomenon: talk about the first experiment is to experiment with loopholes Not long ago, a physical teacher in Shanghai Experimental Competition held a test, there is an oil film method to measure the molecular diameter of the experiment, the experiment does not require any advanced equipment and methods, that is, prickly heat powder, oleic acid solution, but these are the simple things But a lot of young teachers, many people do not know how to sprinkle prickly heat powder, how drops of oleic acid solution, and some spoonful of spoon to the water with a spoon; some number of oil droplets, how many drops of oleic acid is 1 ml ... A survey of physics teaching in secondary schools in Shanghai shows that students' most interested in physics classes are doing physics experiments, including watching teacher demonstration experiments. '' Teaching students to do experiment 'is exactly what most of our physical teachers are not good at. "Tang Qingxiu, a Shanghai physics researcher, said that the teachers talked about the experiment but they both said the first word. "Many experiments repeated as long as repeated practice, students can actually test a good score." Tang Qingxiu said with concern, "Some experts have suggested that we can in the test proposition, the experimental ability to reflect that we are In recent years, there are also many experimental subjects in the college entrance examination written tests. However, the teachers are very capable and have developed a set of reviewing materials for the experiments. They do not have to go through the experiment and can all take the test Dr protalk. Now many teachers are 80, highly educated, for computer, Flash and other information technology can be familiar with the multimedia courseware, "talk about the experiment" than "experiment" is much easier. However, many experimental classes are time-consuming and labor-intensive. Therefore, experimental classes in schools can not be conducted without experimenting. Students who do demonstration experiments are not allowed to experiment with them. According to a survey conducted by a district in Shanghai, the current rate of students in experimental classes is less than 80%. "The Shanghai pilot rate has been very high, many other places in the country can reach 50% is not bad." Shanghai Primary and Secondary Digital Experimental System R & D Center, deputy director, Shandong Grand Science and Technology Group, said Li Ding, general manager. Due to working relationships, Li Ding often to schools throughout the country responsible for the experimental equipment after-sales service. He said: "In some schools, the experiment table is completely gray, and you know that you have not done experiments in a few months at a glance, and some of the school's teaching instruments have not even opened their boxes, and even some of the school laboratory doors are locked in perennial " The new national curriculum reform attaches great importance to experimental teaching, and increases the weight of experimental teaching in the new curriculum standard. Some areas like Shanghai in the new curriculum standard, the experimental content from the original 12 to 22, and added the content of the experiment in the college entrance examination proposition. In the school experimental equipment equipped, both at the national and local levels have invested heavily, especially in the western and rural areas,The new PolyU e Admission portal is a one-stop platform aimed at handling applications of university degree courses. With PolyU e Admission, the application process is refined into three simple steps. However, the reporter learned from the interview that there are many problems such as the low rate of experimental classes, fewer opportunities for students to practice their hands, weak teachers 'ability to practice their own hands, and weak experimental awareness in schools. If this situation continues to develop, it will seriously affect the students' abilities and The cultivation of innovative thinking is likely to lead to the lack of national engineering talents in the future.
