Five essays on teaching work summary and reflection [5]

In a twinkling of an eye, the second-grade mathematics teaching work is about to end. In the teaching process, there have been confusions and gains. Now we summarize them as follows:

一、 focuses on operational activities to help students understand the meaning of division

Through teaching practice, I think that teachers must pay attention to the actual operation activities of dividing objects and combine the operation and thinking in the teaching of "the initial understanding of division".具体：

First, introduce the understanding of division through the operation activity of average score. The textbook first uses the activity of preparing food for spring outings, from "should get the same amount of each portion" leading to the "average score", so that students can realize that "each portion should get the same amount, which is called the average score." Then, through Example 2 and Example 3, let students experience the process of "average score" and establish the concept of "average score". Through the actual operation activities of scoring one point, students can further understand the meaning of division.

Secondly, I used to think that the operation activities are relatively "low-level", so students should be free of operation as much as possible. Through the teaching practice of this unit, I deeply realized that the practical operation is not only in line with the cognitive characteristics of elementary school students. , And if you can combine thinking and operation organically, operation will help students understand what they have learned, and operation is also an important problem-solving strategy.

二、Implement practical activities to cultivate students’ ability to estimate large numbers

In the first grade of study, students have already estimated some small things, such as grabbing a small stick and estimating how many sticks there are. This textbook requires students to estimate the approximate number of people that can sit in the gymnasium. The second-year students still have a certain degree of difficulty in estimating such a large number of things, so I combined real life to arrange some materials that need to be estimated in life, according to the reason The easy-to-difficult slope is designed to guide students to gradually experience the method, and also enables students to experience the wide application of estimation in real life.

三、Improve the calculation skills of "addition and subtraction within a hundred"

Explore and master the oral arithmetic of the addition and subtraction of the whole 十、整百数 and the calculation method of three digits, and be able to calculate correctly and solve some simple practical problems. This is one of the important goals of this book of mathematics learning 1. How to improve the basic calculation skills of adding and subtracting within a hundred? Search related information on the Internet and ask teachers of the same level for advice. In teaching, the following methods are mainly used:

First, let students explore the calculation method of three-digit addition and subtraction independently on the basis of having mastered the addition and subtraction of numbers within a hundred, understand the principle of calculation, and combine the "buy electrical appliances" and "collected mineral water bottles" created by the textbook. In such situations, students are encouraged to discover and solve problems in real situations. Due to students’ life background, knowledge and experience, and different angles of thinking about problems, students use different methods to calculate three-digit addition and subtraction.

Second, the number of three-digit addition and subtraction is relatively large, and errors are prone to occur in calculations, so I think that we should cultivate the habit of students to do the questions seriously.

Thirdly, design various exercises such as the "Forest Doctor" fun game to help students perform calculations correctly.

Fourth, arrange the practice stage reasonably, practice in time and give feedback in time for the new learning content, because forgetting is fast and then slow. Pay attention to the combination of concentrated practice and scattered practice. It is also appropriate in the learning of the subsequent units. Interspersed with related exercises.

Reflection:

1.When this class is in class, most of the students can concentrate on listening and finish their homework carefully after class. However, there are a few students who dare not ask the teacher if they have problems in their studies, and copy their homework for fear of low scores. Someone else's.

2.Some students are not very interested in learning mathematics, and they are not able to concentrate in class. After repeating a question two or three times, some students still don't know how to do it.

3.The student's ability to examine questions is not serious. For example, it is easy to misread symbols and copy numbers when calculating, especially when calculating.

The direction of effort:

1. pay close attention to the style of study and promote a style of chasing after me in the class.

2.In the future work, you should always learn from experienced teachers to make up for the deficiencies in your math work.

3.In terms of subject research, we must boldly explore, innovate, reform, and continuously improve the efficiency of education and teaching.

In short, the past is over. We sum up the past to make the future more experienced. The old year has passed, and in the new semester, we learn from the past experience and lessons, and constantly improve ourselves so that we can move towards a higher goal. I firmly believe that every effort is rewarded.
