Five-Self Method: Explorations and Breakthroughs in my country’s Educational Reform Zhou Zhongzhi, deputy director of the Teaching and Research Office of Qidong No. 1 Middle School in Hunan Province, has been based on reality since the 1980s and began experimental research on educational reform. After more than 20 years of After arduous exploration, I finally created the five-step self-study method (Five-Self Method). This is a brand-new teaching model and education system that integrates three dimensions and five rings, that is, it is embedded in the five rings of "self-study, self-care and self-improvement". Classroom teaching is mainly based on students' self-study. Students read (read) and take notes (writing) by themselves in class. Self-thinking (thinking), self-memorizing (memorizing), self-assignment (practicing) to master knowledge and skills and complete studies; teaching organization and class affairs. Extracurricular activities are basically taken care of by students themselves; students learn to strengthen themselves through self-study and self-care. A series of achievements have been achieved in recent years, and its practical innovation and theoretical construction have been affirmed by experts and recognized by all walks of life: the Five-Self Method "has made a new division of classroom teaching time" and "integrated 'individual teaching' in the teaching organization. It combines the two major advantages of "class teaching", integrates the essence of "receptive" and "inquiry" in the way of receiving knowledge, and organically combines traditional teaching with modern education. It is the most popular teaching method in middle school classrooms in my country. , has made major breakthroughs and innovations in methods. "It has played a positive role in promoting the in-depth research on the theory and practice of my country's teaching model." The five-self method follows the student-centered concept, fully respects the individuality of students, and teaches students in accordance with their aptitude. Learning itself becomes vivid, students' thinking becomes active, and knowledge teaching and reception are pleasant and interactive. It is very popular among students, especially those who are not comfortable with traditional exam-oriented education.
“The Five-Self Method has adopted a series of specific strategies and measures during the implementation process, such as editing self-study tutoring materials and testing learning effectiveness in a variety of ways. This not only reflects the completeness of the experimental process, but also provides Summarizing and promoting the experimental results has laid a foundation. "The Five-Self Method has achieved success in the reform of history teaching in middle schools, and has now made theoretical explorations and attempts to transfer it to corresponding subjects such as politics and geography in middle schools. At the same time, it has provided feasible solutions for the overall reform of basic education. New ideas.
Energy-saving and efficient rotary closed three-dimensional jet parts cleaning machine
The rotary closed three-dimensional jet parts cleaning machine uses solar energy to heat the synthetic detergent and uses the potential energy of the liquid to Clean parts are jet cleaned to save energy. Using mechanical boosting, electrical auxiliary heating, and the rotation of the drive plate, the parts to be washed continuously change the cleaning surface. Under the physical action of the three-dimensional jet in the cleaning machine and the emulsification of the cleaning fluid, the sludge falls off faster, achieving high efficiency, high cleanliness, and low cost. Cost effectiveness of cleaning parts. Features: ① Wide range of uses, ingenious conception, scientific and reasonable design, original innovation, international unique, filling the domestic gap. ②High efficiency. At present, there are no reports at home and abroad that parts cleaning can meet the cleaning quality requirements in only 3 to 5 minutes per batch (batch). ③Low energy consumption. Solar heating and high-efficiency cleaning have obvious energy-saving effects. ④New technology. It can automatically remove sludge, automatically filter, and has new technologies that other cleaning equipment does not have. This patent has a good market prospect and is now available for transfer at a low price.
Combined grain storage
The utility model is a kind of grain storage equipment, specifically relates to a durable grain storage composed of prefabricated building parts, and belongs to the international patent classification E04H7 /22 "Containers for flowable solid particles, such as silos and hoppers." Including hoarding caps, hoarding girth and hoarding bottoms. The enclosure is composed of two upper and lower sections. Two prefabricated panels are overlapped as the upper section, and the other two prefabricated panels are overlapped as the lower section.
