Self -made teaching aids, editable, this Wuhan high school female teacher’s mathematics class has endless fun

Lead the students to collect the split of trees, observe the number of petals, and experience the mathematics in nature; learn the interest rate sheet of banks, understand the actual calculation of deposit interest, house purchase loans and other actual calculation issues to the bank staff, and experience the mathematics in finance; Go to play marble games in the playground, understand the dual -e -terms theorem and probability, and experience mathematics in life. Tang Wen, a mathematics teacher in Jiangxia District First Middle School, is a "post -80s". Since 16 years of teaching, she has followed the "education must start with the experience of learners" by the well -known educator Duwei. Experience and discovering that Zhongshan learns with students and explores a set of "literary mathematics" teaching methods.

Plastic bottles and fruits are her teaching aids

Tang Wen, a mathematics teacher in Jiangxia District First Middle School.

Tang Wen's classroom is full of inquiry. She is willing to change her identity and learn with students to inspire students' thinking and stimulate students to discover, so that students can summarize the laws.

When telling the knowledge point of the image of the sine function and the string function, Tang Wen tied a small hole into a funnel at the bottom of the plastic bottle, and then hung it on the shelf to make a simple single. Put a cardboard under the funnel, and draw a straight line in the middle of the board as the horizontal axis of the coordinate system. Pull the funnel and pull away from the balance position, let it let it swing, and pull the cardboard at the same time, so that you can get a curve on the cardboard. Through this experiment, students have an intuitive impression on the images of sine and string functions, combining physics and mathematics scientifically to taste the fun of learning mathematics from the examples of life and enjoying mathematics.

Tang Wen is both the "Teacher Tang" of the students and the "Sister Wen Wen" of the students.

Another example is that when learning the triangle function of any corner, she made a disc, installing two pointers on the disc, one as the beginning of the horn, unintentional with the X -axis, and the other as the end side as the end side Rotate on the disc, so that students can see at a glance, clearly understand the concept and formation of any corner, and the symbol of the triangular function value of the angle.

When studying "Arrangement and Combination", Tang Wen brought five different fruits each to the classroom, allowing students to answer one, two, three, four, and five different results from them. Essence Let students understand the combination from the instance operation and find the relationship between the combination. And give the fruit reward to the correct students. The students enjoyed the fun of learning, and the sweetness of the fruit was filled with the entire classroom.

Tang Wen led the students through the "successful door".

What's more worth mentioning is that Tang Wen also summarized the boring mathematical formula theorem and the regular conclusions of students' dizziness, etc., as one by one, so that students can easily remember and learn happily and easily. For example: vector -vector variable volume, point multiplication or square, deformation and simplification, increased and reduced points; linear planning -drawing line is the point of seeking points, the goal significance must be obvious, the baseline slope contains parameters, and the upward and falling movement is left or right. Such "literary teaching" can not only allow students to learn and master relevant knowledge points faster and better, but also make her a role model for other teachers.

Select "Mathematics Star" every half month

Every time the activities are carried out, Tang Wen is the object of the students who scramble to take a group photo.

When serving as the leader of the high school mathematics group, Tang Wen broke the regular collective preparation form, and carried out the "everyone to take a class" activity once a week. After listening to the class collectively, the teacher took the lessons as the focus of the collective lesson this week. It is better to concentrate on everyone's intelligent discussion and study how this lesson should teach better. Based on this, arrange the teaching plan for next week. The initiative of this "non -step -by -step" made the preparation team the most vibrant, enterprising, united and cooperative collective in the eyes of the school leaders and colleagues.

At the same time, Tang Wen extended this "competition" to the students. In order to create a learning atmosphere that you fight for me, you chase me, and make a positive learning atmosphere, let students understand their positioning more clearly and establish a larger learning goal. "Activity. After the math testing every half month, the highest score of each class is the "Star of Mathematics" in the class. It was announced on the electronic demonstration screen of the teaching building.

"Good ways to share, good learning partners to promote growth." This activity has been well received by teachers and students. Students are constantly catching up and challenging to the "Star of Mathematics".

Send away the 2022 graduates, and this summer vacation Tang Wen has invested in the preparation of the freshman of the high school. After returning to senior high school questions and information, she also re -studied the guidance case of the first volume of high school in high school. In addition, she bought books such as "The Secret of the Coneva curve", "The Secret of the Division", "How to Be a Teacher Today", and use the holidays to continue to "charge" to improve herself.

"I just completed two papers, and I went back to school after a few days." Tang Wen had an old habit: before the school started, she would clean up every corner of the office, so that everyone was enjoying a beautiful and relaxed one. After the holiday, you can enjoy a long -lost comfort as soon as you enter the office in the new semester.

"From the sixteen years of teaching, she did not forget her original intention, and the enthusiasm of her three -foot podium continued." The old colleagues said that Teacher Tang always asked herself with 10 words: wise teaching and education with heart.Each of her cultivation is to make students better unplugged.(Changjiang Daily Reporter Xiang Jie Correspondent Chen Kemao Intern Hu Mingzi) [Editor: Deng La Xiu]
