In the textbook, we can see that the teaching content shown to us is actually very simple, but the teacher continues to study the textbook carefully and clearly understand the mathematical knowledge to be passed on to students in each example and the cultivation of students' mathematical literacy. Students' children can actively participate in the classroom, and hands-on operation can also have the expected effect. When drawing statistical charts, students feel the information and find the advantages of composite bar statistical charts: they can not only see the quantity, but also intuitively find the relationship and contrast between different things. Drawing statistical charts not only arouses students' existing knowledge and experience in making statistical charts, but also fully experiences that it is too troublesome to draw and observe alone in the process of drawing and comparing, resulting in cognitive demand for composite statistical charts and accumulating students' metacognitive experience. Students have a deeper understanding of the advantages and characteristics of composite bar charts. Teachers let students discover, discuss and explore new knowledge according to their own foundation and ability! The ability to make such an accurate judgment lies in teachers' in-depth reading of teaching materials and their ability to jump out of teaching materials. Then the teachers made all the preparations, leaving enough room for their thoughts and giving full play to the autonomy of the first child.
From this lesson, we can easily see that xu teacher attaches great importance to cultivating each student's ability of independent exploration, observation and analysis, and also advocates cooperation and communication among groups. For example, the guidance to students in the transition from single bar chart to composite bar chart; In particular, how to draw a composite bar chart is to really let students explore independently, talk about ideas in groups and constantly improve themselves in communication. It truly embodies the organic combination of teacher-led and student-centered.
We know that the real purpose of curriculum reform is to promote students' all-round, harmonious and sustainable development. While paying attention to knowledge transfer, students should be allowed to experience the process of knowledge acquisition, gain their own experience and sentiment in the process of learning, enrich their learning experience and improve their interest in learning. In this lesson, the teacher continues to design how to draw a composite bar chart, which is to let students experience: why to draw a composite bar chart-how to draw a composite bar chart-how to distinguish the content of a statistical chart, etc. They are all acquired by students through self-exploration, cooperation and communication, which truly explains the word "experience".
In teaching, teachers' friendly tone, persuasive guidance, equal and democratic dialogue and serious evaluation have narrowed the distance between teachers and students. Students are fearless, willing to learn, willing to think and dare to speak. In a relaxed and harmonious atmosphere, the main role can be fully played. Let students discover problems, explore knowledge, understand methods and sum up experience, so that students can truly become the masters of classroom and learning. Xu teacher has a goal in mind, and classroom teaching is real and effective.
? Every teaching link of the teacher continues in detail, and the small teaching objectives are very clear. Be meticulous and solid in the specific treatment, let students fully interact, reach a * * * knowledge, and truly implement the teaching objectives. Facing students of different generations, we should not be anxious, not shrink back, actively respond, provide materials and organize experiences, and "we will never give up until we reach our goals". Step by step to achieve each footprint, footprint link is the target trajectory of the whole class teaching, clearly visible, true and effective. Xu teacher's ingenious teaching design and humanistic care for students all reflect his profound teaching skills and novel teaching ideas.
