original title: expanding hands-on scenarios, connecting venue resources... new changes in science classes in the new semester
when the semester started in the fall this year, many places made new adjustments to science classes. not only did the courses keep up with the scientific frontiers of new technologies and new applications, but the teaching design also focused more on cultivating students' scientific interests and improving their innovative capabilities, striving to make science classes more "scientific."
many places have increased scientific practice activities to expand hands-on operation scenarios
zhengzhou, henan province, was named one of the "first national primary and secondary school science education experimental zones" this year. in the new semester, during the after-school extended service at jianshe road primary school in zhengzhou's zhongyuan district, students conducted a hands-on water-oil separation experiment - pouring water, oil and effervescent tablets into a cup can simulate a volcanic eruption.
feng jiaqi, a student at jianshe road primary school in zhongyuan district, zhengzhou city: because the density of water is greater than that of oil, the oil will be above the water, and they are separated as if by a dividing line.
not only has the school introduced interesting scientific practices into after-school extended services, but this semester, the school has also increased the number of science classes for first and second graders.
while encouraging flexible scientific practice in the basic education stage, zhengzhou city has also launched the "school science education quality improvement plan" this year to improve the professionalism of science teaching in primary and secondary schools. this is a science flight class at zhengzhou no. 84 middle school. in order to teach this class well, the school not only upgraded the traditional model aircraft courses, but also cooperated with professional venues and institutions such as the henan science and technology museum and zhengzhou aviation management college to move the dynamic simulation operation cabin of the aircraft into the classroom.
in the new semester, high school students from the science and technology middle school affiliated to xiamen university in fujian province entered university laboratories to practice hands-on techniques and experience the charm of science.
starting from september this year, the fujian provincial department of education will sort out various types of venues and resources with scientific educational value in provincial agencies, and open them to primary and secondary school students free of charge on a regular basis. it will also create a special resource list and release it to the public.
connecting the scientific and technological resources of the venues to empower school science education
last year, the ministry of education and 18 other departments issued the "opinions on strengthening science education in primary and secondary schools in the new era", which clearly stated that relevant units should be fully mobilized to serve scientific practice education. in the past year since the release of the "opinions", how have various regions opened up the scientific and technological resources of venues to empower scientific education in primary and secondary schools? let's take a look at the reporter's investigation.
in the new semester, the fujian provincial department of education, together with 24 departments across the province, issued a specific implementation document for the free opening of fujian's "100 museums and 1,000 schools" and distributed it to every primary and secondary school in the province. the reporter learned that a special link for the design of museum-school cooperation courses was added, with the aim of changing the past "rushing" visiting mode.
xiu demao, director of the extracurricular education and training supervision department of the fujian provincial department of education: some teachers have told us that students are tired of going to the same place and visiting the same place every year, and the teachers don’t know what to teach, so the purpose of scientific education cannot be achieved.
during the visit, the reporter learned that for some time, primary and secondary school science education has mainly relied on the school's own science classrooms and on-campus laboratories. going to scientific research institutes and science and technology museums is often an extracurricular activity that is more about visiting than learning. in the new semester, more than 300 university laboratories and science and technology venues in fujian province began to provide "customized classrooms" for primary and secondary school students, and together with school teachers, jointly designed the entire process of extracurricular science classes.
cai minggang, professor at the state key laboratory of marine environmental science, xiamen university: it is not just hands-on work. science is bound to make mistakes and various problems will inevitably arise. in this process, students can experience a real scientific practice process. for teachers, we hope to make the connection between university professors and middle school teachers more direct.
the scientific research sites opened to primary and secondary school students in fujian province this time cover cutting-edge science, agriculture, environment and other types. this is a science education course jointly developed by the sanming academy of agricultural sciences and a local nine-year school. the staff of the academy of agricultural sciences have become the school's resident science teachers and give regular classes to the children.
in gushi county, henan province, an old revolutionary base in dabie mountain, the local government has also opened up the popular science resources of the education and sports bureau, the science and technology museum and the science and technology association to customize science practice classes for all primary school students in the county. in the new semester, the gushi county science and technology museum also cooperated with nearby universities in hefei, anhui province to provide training for science teachers in the county, focusing on improving their hands-on skills.
this giant water rocket, made from four 12l standard discarded pure water bottles, was created by a township science teacher in gushi county. it can fly in the air for more than 40 seconds and can automatically open a parachute for recovery in the air.
township science teachers "weld" laboratories for students
filling the gaps in rural science education is an important measure to achieve balanced development of education. let's go to a township middle school in ningbo, zhejiang, and see how rural science education can make children in the mountains full of imagination and creativity.
teacher jiang chunjie of shencun town junior high school in ninghai county, ningbo city, is a national expert in making his own teaching aids and a well-known "treasure science teacher" in the town.
jiang chunjie, a science teacher at shencun junior high school in ninghai county, zhejiang province: the reason why we first made teaching aids was that our experimental equipment could not meet the needs of teaching. for example, the sound characteristic demonstrator, we could only tell students about ultrasound and infrasound before, so i tried to make teaching aids for those experiments that could not be done using modern technology.
camera imaging principle demonstrator, sound characteristics demonstrator, hydrogen explosion limit testing device... for more than 20 years, jiang chunjie has created a science classroom for rural children that many city children envy through self-developed and self-made teaching aids.
with the popularization of computers, jiang chunjie has a new goal: to build a programming device that all children can afford. in 2022, through self-study and research, jiang chunjie integrated the writing, compilation and operation of basic language into a computer programming device that costs less than 100 yuan and integrates the junior high school science curriculum. at the same time, he also developed 16 supporting activity projects.
instead of using a host computer or a screen, students can write, compile and run programs on a palm-sized programming device by simply plugging in a keyboard. the introduction of computer programming education in remote township middle schools not only brings children a novel and interesting technological experience, but also plants the dream of science in their hearts.
through scientific experiments, jiang chunjie took the children to see a different world, and the students' interest and feedback became jiang chunjie's greatest motivation.
over the years, jiang chunjie has spent half of his salary on making teaching aids. he converted his own utility room into a small laboratory and spends his time there whenever he has free time. he wants more children to use the equipment he made.
let scientific education grow rapidly towards the future
the reform of science classes in the new semester allows children to play with science with their hands and feel science with their hearts; the integration of science and technology venues and schools makes science classes no longer a "cursory tour". a series of measures make scientific knowledge more vivid and closer to life. the buds of learning and loving science take root in the hearts of children in these little changes and grow towards the future.
