Elementary understanding of decimals, self-reflectionAfter the initial understanding of decimals, you can reflect on yourself from the following aspects:
** 1. Teaching preparation **
1. ** Grasp the Starting Point of Teaching **
- Although the logical structure of decimals was new, the students had a preliminary intuitive understanding of decimals based on their life experiences (such as shopping in the supermarket). This point should be fully taken into account in lesson preparation. It should accurately determine the starting point of students 'knowledge, reasonably design the teaching content, and introduce the concept of decimals from the familiar scenes of the students, such as the price of goods in life, height and weight, and so on.
2. ** Confirm teaching focus **
- Reading and writing decimals was relatively easy, and most students had a shallow understanding of the meaning of decimals. Therefore, the focus of teaching should be on understanding the meaning of decimals, especially the decimals that express length in meters. Students can be guided to understand the relationship between decimals and scores with the help of scores. For example, 1 decimeter = 1/10 meters = 0.1 meters, so that students can understand that a fraction of a fraction can be expressed in one decimals.
** 2. Teaching process **
1. ** Give full play to the role of students as the main body **
- By collecting students 'questions about "decimals", the students were helped to sort out the general path of studying numbers in the form of question strings (the meaning of numbers, reading and writing, size comparison, calculation, application). When teaching the meaning of decimals, visual aids such as the meter ruler were used to demonstrate, so that students could actively construct knowledge based on the existing knowledge of the relationship between meters and decimeters.
- In terms of questioning skills, they should pay attention to the value, effectiveness, and targeting of the questions to stimulate students 'mathematical thinking. For example, when exploring the meaning of decimals, the questions raised should be able to guide the students to dig deeper into the meaning of decimals, such as "how many 0.1 meters are there in 1 meter" and so on.
2. ** Focus on mathematical thinking and core accomplishment cultivation **
- Combining specific "quantity"(such as length, area, etc.) and intuitive and semi-intuitive models (such as ruler, number axis, etc.), using the idea of combining number and shape, let students experience the process of abstracting "number" from "quantity", cultivate students 'sense of number and quantity, and promote the formation of core literacy.
- However, there might be some shortcomings in the teaching process. For example, when teaching the meaning of decimals in meters, students should strengthen their ability to speak and the process of speaking, so that students can better internalize their knowledge into their own understanding.
3. ** Control time and rhythm **
- There might be some unreasonable allocation of class time. For example, in some segments (such as the "Realm of Decimals" segment), due to time constraints, it could not be implemented as expected, and the role of encouraging outstanding students was not fully played. Or some knowledge points (such as the conversion of five jiao and eight cents into 5.08, the zero in the middle was easily ignored by students) were not emphasized enough, resulting in students 'misunderstanding or errors.
** 3. Teacher's self-accomplishment **
1. ** Language expression **
- In the specific teaching links, we should pay attention to the accumulation, comprehension and application of language, temper the language, make the explanation clearer, more accurate and concise, and avoid ambiguity or misunderstanding.
2. ** Guidance and Inspiration **
- In the classroom, students should be guided to observe and think more, give students enough time to express their ideas, cultivate students 'problem awareness and mathematical language expression ability, improve students' initiative to explore and independent learning ability, and let students truly experience the joy of learning decimals.

Understanding of Lu Xun's Self-Inscribed PortraitLu Xun's Self-Inscribed Portrait was a poem he wrote for his own portrait, expressing his self-mockery of his own appearance and his confidence in his own personality.
I was originally an ordinary person in Han
why should we go to the Western Paradise to fetch the scriptures?
Like a dead tree without a master
my heart is like a stone in a cold pool, never dying.
I've used up my talent, but my brain can't stop my ambition
in reading I have no end, imitating Lao Tzu and Chuang Tzu.
The words under my pen are like flowing water
His thoughts were like a hurricane.
Such a pale life
I hope to borrow the divine pen to mend the heavens.

Philosophers, as things now stand, are all too fond of offering criticism from on high instead of studying and understanding things from within. -Edmund Husserl
