First, reflect on the problem.
1, the use of teaching AIDS is not standardized. The clock on the courseware is round, but I use a rectangle, which may reduce the connection with life.
2. Sometimes I worry that the teaching time is not enough, and the time for students to express themselves needs to be strengthened. Let go when it is time to let go, so that students can truly become the main body of the classroom.
3. The language is not refined enough. The teacher only said 1 1 in a class, but failed to do it.
Second, success.
1. At the beginning of this class, I showed the video of life countdown with courseware, which immediately attracted the students' attention, improved their interest in learning, and let them intuitively understand the existence of "seconds" in life.
Introduce the topic through the countdown, let students feel the length of "1 second" initially, and help them understand the abstract concept of time. Achieved the purpose of creating situations to stimulate interest. The teacher seized this opportunity to let the students understand that the time unit has a smaller time unit "second" besides the hours and minutes we used to know, so the topic was naturally introduced.
2. Know 1 second, 5 seconds, 10 second, 60 seconds, etc. Through the courseware, let the students observe the courseware and count it. I think 1 is one second, a big grid is 5 seconds, and a circle is 60 seconds. Ask, "Is it 10 seconds from 12 to 10?" Develop students' thinking.
When the teaching time is 1 = 60 seconds, ask "How can the pointer go once 1 and then go for 60 seconds?" , causing students' cognitive conflicts. After students express their ideas, through observation and communication, guide students to explore the relationship between minutes and seconds and summarize the progress rate between minutes and seconds.
3. The new curriculum focuses on "experience". In the classroom teaching, I designed a variety of activities to create a harmonious, equal and democratic teaching culture atmosphere, to maximize the mobilization of students' main role, so that students can step out of the simple role of "listener" and "responder" and become "thinker" and "doer".
Students' eyes, ears, mouth, hands and other senses can participate in activities at the same time, learn mathematics by "experience", give full play to students' main role, and fully experience 1 second, 1 second, 30 seconds,1minute, thus helping students to establish the concept of "second". It not only improves students' interest in learning, but also cultivates students' spirit of exploration.
4. Integrate mathematics teaching into life application through interesting topics, bring mathematics problems into life, and improve students' knowledge level of applied mathematics. In practice, let students connect with their real life. Through the practice of "I am a time manager" and "I will judge the reasons", let students feel that mathematics knowledge comes from life and is applied back to life, so that students can feel close to mathematics.
5. Educate students to cherish time through the famous sayings about cherishing time, and form the habit of cherishing time, such as: "An inch of time is worth an inch of gold, and an inch of money can't buy an inch of time" and "If a teenager doesn't work hard, the boss will be sad".
Third, teaching experience
The teaching content of this lesson includes knowing the clock, knowing the time unit and the second, and exploring the relationship between the minute and the second, which involves many contents, abstract knowledge and large capacity. As long as teachers fully prepare lessons, arrange time reasonably, properly use audio-visual teaching methods, highlight teaching priorities and break through difficulties, students will be able to master what they have learned skillfully.
If I am allowed to teach this lesson again, I will strive to improve my quality, grasp the psychological characteristics of students, sum up my own shortcomings, and ask for quality in 40 minutes. Teaching practice makes me feel that teachers' teaching methods determine students' learning state and effect, and teachers' teaching art affects students' lifelong learning and development. Therefore, teachers should constantly explore teaching and integrate into curriculum reform, so that the teaching effect will be better.
