"Try to find and raise problems in real situations, explore the use of geometric and intuitive methods to analyze and solve problems, and form model consciousness and preliminary application consciousness and innovation consciousness" - this is one of the learning objectives proposed by the Compulsory Education Mathematics Curriculum Standards (2022 Edition) for grades 5 and 6.
The core of the lesson "Drinking Juice Problems" in primary school mathematics is to guide students to explore the use of geometric and intuitive methods to solve practical problems in life.
In the classroom teaching of the fifth-grade mathematics "Drinking Juice Problem" of Xingguo School of Tiyu East Road Primary School, Tianhe District, Guangzhou City, Guangdong Province, teachers and students completed the whole process application of "reading and comprehension, analysis and answering, review and reflection" with the help of Qinglu smart pen and paper system, and promoted the achievement of learning goals with diversified classroom interaction and first-class activity feedback.
In the analysis and answering session, the teacher sets up ** activities through the question chain layer by layer, and the students use the Qinglu smart pen to complete the tutorial case, and complete the learning process from "** add 1 time of water - * add water many times - discover the universal law", step by step to promote students' thinking, trigger diversified learning practices in the situation, and realize the advancement of geometric intuitive strategy problem solving.
In carrying out the first activity, the Qinglu smart pen is used in combination with the tutorial case, which can not only realize the accompanying collection of students' answer handwriting, thinking characteristics, time length, etc., but also support the playback of the answer track when students share and comment, and efficiently support the whole class to share the students' process and results, help teachers clarify the logic and process of students' thinking in a timely manner and make targeted comments and corrections, so as to promote students' knowledge mastery and standardized learning.
In addition, after the class, the teacher can also log in to the "Qinglu Teaching Cloud Platform" in the office to view the details of the answers and the process of the rest of the students in the classroom report, conduct answer correction and classroom review, clarify the completion of classroom learning objectives, and promote follow-up teaching adjustment and student training.
