Design template and reflection of junior high school physics current inquiry teachingThe following is a junior high school physics current exploration teaching design template:
** 1. Teaching objectives **
#(1) Knowledge and Skill Target
1. Students can have a deep understanding of the concept of electric current, be familiar with the unit of electric current and its conversion relationship, and be able to accurately say common electric current values.
2. Familiar with the structure of the ammeter and master the correct method of using the ammeter to measure the current value.
#(II) Method, process, and goal
1. By exploring the concept of electric current and carefully reading the instruction manual of the ammeter, it can effectively improve the self-learning ability.
2. In the process of observing the electric current, he gradually cultivated his keen observation ability.
3. Through practicing the usage of the ammeter, he could continuously improve his hands-on operation ability.
#(3) Emotional attitudes and values, goals
1. In the process of experimental exploration, through the successful experience to stimulate a strong interest in learning.
2. Learn to work closely with the group members to develop a rigorous and scientific learning attitude.
** 2. Important and Difficult Points in Teaching **
#(I) Teaching Focus
1. Thoroughly understand the concept of electric current, including its size, unit, etc.
2. Proficient in the use of ammeter, covering the connection method of ammeter, range selection, reading method, etc.
#(II) Difficulties in Teaching
1. Accurately understand the relationship between the amount of electric charge and time in the concept of electric current, that is, the calculation formula of current intensity (I = Q/t).
2. The measuring range of the ammeter could be reasonably selected according to the actual measured current, and some common wrong operations could be avoided during the use process, such as the positive and negative terminal being connected in reverse, and the measured current exceeding the measuring range.
** 3. Teaching Method **
Teaching method, experiment method, discussion method, and inquiry method were combined.
** 4. Teaching process **
#(1) Introduction of the scenario (about 5 minutes)
1. Show a simple circuit that lacks power. The light bulb doesn't light up after the switch is closed. Guide the students to think about the reason why the light bulb doesn't light up.
2. He raised the question,"In the circuit, what factors determine whether the light bulb will light up?" This led to the concept of electricity.
#(2) Self-learning (about 10 minutes)
1. Let the students study the part about the concept of electricity in the textbook (for example, page 52 of the textbook) and complete the related questions on the tutorial (questions 1 - 3).
2. Please read the answers to some of the questions and explain the conversion of electric current units to your classmates.
3. Guide the students to learn the current of common electrical appliances on their own (lower left corner of page 53 of the textbook), and then consolidate the content through two simple training questions.
#(3) Understanding the ammeter (about 10 minutes)
1. Show the ammeter and ask the students how to measure the current of the common electrical appliances mentioned before.
2. Students were required to carefully observe the ammeter and find its important components, such as the zeroing knob, the terminal, the measurement range, etc., and complete the part on the structure of the ammeter on the tutorial.
3. Show the students the reading of two ammeters. Let the students try to read the ammeters.
#(4) Use of ammeter (about 15 minutes)
1. Guide the students to learn the part of the textbook about the use of the ammeter (page 53). Complete the content about the use of the ammeter on the tutorial. After completing it, communicate with each other.
2. Students are invited to share their own summary of how to use the ammeter, and the teacher will supplement and improve it.
3. Show a simple circuit diagram. Have the students connect the circuit according to the circuit diagram in pairs. Use an ammeter to measure the current passing through the light bulb and record the data. During the student's experiment, the teacher would patrol and guide the students to find and solve the problems encountered by the students in time.
#(5) Inductive summary (about 5 minutes)
1. Guide the students to review what they have learned in this lesson, including the concept of electric current, the unit, the structure of the ammeter, how to use it, and the gains from the experiment.
2. Students are asked to make a summary by themselves, then discuss in the group, and finally, the group will send a representative to answer.
#(6) Assignment
Arrange some after-school exercises related to the concept of electric current and the use of an ammeter. For example, the written homework could be to let the students calculate the current under a given amount of charge and time. The practical homework could be to let the students measure the current of a simple electrical device (such as a flashlight bulb) when they go home.
** 5. Reflection on Teaching **
#(I) Success
1. Through the introduction of the situation, starting from the circuit phenomenon that the students were familiar with, it could effectively stimulate the students 'curiosity and thirst for knowledge, so that they could actively participate in the classroom learning.
2. In the teaching process, a variety of teaching methods were combined to give students sufficient self-learning space, such as self-learning the concept of electric current, common electric current values, and the use of ammeters. This helped to cultivate students 'self-learning ability. At the same time, the experimental operation segment allowed the students to experience the use of the ammeter, which improved their hands-on ability and teamwork.
3. In dealing with the important and difficult points of teaching, they adopted a step-by-step guidance and in-depth method. For the important and difficult parts of the concept of electric current, it was explained through simple life examples (such as water flow analogy electric current) to help students better understand. In the teaching of the use of the ammeter, from understanding the structure of the ammeter to the actual operation, and then to the summary, the students gradually mastered the use of the ammeter.
#(II) Inadequacies
1. In the self-learning segment, some students might not be able to efficiently complete the tasks on the tutorial plan due to their weak foundation or inappropriate learning methods. In the future, he could strengthen the individual guidance for these students or provide some guidance on learning methods to the students in advance.
2. In the experimental operation section, although some students 'problems were solved in time during the inspection, some students still had difficulties in selecting the ammeter range and reading. In the next lesson, he could add some special exercises on range selection and reading, and emphasize the key points of operation again before the experiment.
3. There was still a need to further improve the control of classroom time. It took a lot of time to explain the use of the ammeter and the students 'experiments, resulting in the final summary section being a little rushed. It did not allow the students to fully express their learning gains and experiences. In the future, he needed to arrange the time for each teaching session more reasonably.
