Former Soviet educator Suhomlinsky

Former Soviet educator Suhomlinsky has repeatedly emphasized that students are the most important force in education.If we lose this power, education will lose its foundation.Therefore, students are not only the object of education, but also important educational resources.Student experience, student interests, student differences, etc. are all resources.In the process of developing chemistry course resources, we should pay attention to the following three aspects: pay attention to students 'initiative and cultivate students' uncertain experience resources.Students 'uncertain experience is actually their existing knowledge level, cognitive structure and social experience, which is the starting point of our teaching, because the acquisition of new knowledge must be based on the students' existing experience.It turns out that in chemistry experiments, experiments designed by students with their own brains and hand-made instruments are more profound than those designed by textbooks and teachers.Therefore, in the teaching process, if the students' inquiry activities are personally experienced, they should not be replaced by experiments in the textbooks or the experience of the teacher.For example, through some experimental design, drug selection, instrument installation, etc., the subjective initiative of the students is fully exerted, and the students are encouraged to replace the reaction vessels with home-made instruments (such as discarded bottles or vials) and cheap calcium carbonate.Replacing sodium carbonate and edible alkali with drugs such as shells or eggs can not only eliminate the mysteries of experiments, stimulate students' uncertain interests, cultivate students' uncertain practical skills, but also reduce the cost of course resources and cultivate students' uncertainty Economic and environmental awareness.Teachers who focus on students' exploration ability can organize students around certain issues, and use the rich curriculum resources such as laboratories, libraries, the Internet, factories, rural areas, and communities to guide students in observation, survey, and experiment activities.Students can solve problems, strengthen innovation, improve innovation ability, and cultivate a spirit of cooperation in the process of exploration.Questions can be asked by the students themselves, or the teacher can guide the students to find out by setting up specific situations.
