In order to further implement the "double reduction" policy, deepen the classroom, improve the effectiveness of classroom teaching, and encourage young teachers to continuously improve teaching methods, promote professional development, and thus improve the quality of education and teaching, from November 9 to 19, 2021, the primary school department of Qiyuan School launched a homeopathic classroom quality class evaluation activity under the "double reduction" policy. On the basis of the open courses within each discipline, 21 outstanding teacher representatives were selected to participate. Each lesson follows the homeopathic classroom spirit of "student-oriented, homeopathic guidance", which fully demonstrates the essence of homeopathic classroom.

  In this activity, the language discipline takes "reading instead of speaking" as the theme, gives full play to the important role of reading guidance in language teaching, so that students can fully read, perceive the whole in reading, generate perception in reading, cultivate language sense in reading, and feel the influence of emotion in reading. According to the characteristics of different grades, teachers find the "entry point" of teaching, dig deep into the core problems of language teaching, vary from birth to birth, teach according to aptitude, and adopt different teaching methods to improve the core literacy of language.

Mathematics disciplines follow the cognitive laws of students, problem-oriented in the classroom, relying on students' campus life situations, guiding students to find problems, asking questions, and through group cooperation and independent exploration, students gain new knowledge, which fully reflects the effectiveness of mathematical learning methods and the flexibility of mathematics; The teacher's instructional design pays attention to the connection between mathematics and life, so that students can realize that mathematics comes from life and is used to solve problems in life.

The English discipline takes "sentence teaching" as the theme, so that students can apply what they have learned, give us an example, present us with the structural beauty of English, and the design of teaching activities takes the use of language as the foothold, so that students can use in middle school, learn in use, combine learning and use, and apply what they have learned, so as to develop language skills, improve the ability to comprehensively use language and the ability of cross-cultural communication.

The three art classes of art, music and physical education pay attention to the aesthetic education and cultivation of students, through understanding the intangible traditional culture of our folk, feeling the beautiful melody, exercising a strong physique, cultivating the students' artistic literacy, so that their "IQ, emotional intelligence and quality" can be fully developed, and more reflect the Qiyuan School's "Combination of East and West, art is strong, personality, all-round development" of the school characteristics and training advantages.

 Classroom teaching is the main front for improving the quality of teaching, and it is also an important way to implement the development of the "five-element quality" of Qiyuan students. In the context of the comprehensive implementation of "double subtraction", the high-quality class competition is a kind of exchange, an exploration, a kind of learning, and also a kind of leadership. This activity not only built a platform for teachers to tap their potential and show themselves, but also promoted the change of everyone's teaching concept, the majority of teachers and colleagues actively optimize the teaching methods, based on the classroom, see the wisdom and wisdom, learn from each other's strengths, deeply cultivate the classroom, improve quality and efficiency, and lead teaching against the standard "double reduction".
