First, create a situation to make students feel excited.
As the saying goes, "A good beginning is half the battle." If we can put more pen and ink and use more brains at the beginning of the activity, make the created teaching activity situation targeted, interesting and creative, and let students learn knowledge from the heart, the activity will often have unexpected effects.
1. Use news import
When learning "infectious diseases and their prevention", we first use the report of the World Health Organization on "Influenza A spread to more than 260 countries, causing many deaths" in the news broadcast to ask students "What is the disease of influenza A? It's terrible. What can cause swine flu? Will we be infected? " And so on, at the same time stimulate students' enthusiasm for learning infectious diseases.
2. Use song import
During the break, the teacher played "Beautiful Grassland My Home" and the music stopped. The teacher asked the students, "Do you know what song you just heard?" That's right. The beautiful prairie My Home reminds us of the vibrant scene of everything. Everything in the world can be reproduced from generation to generation with great interest because they have the basic characteristics of reproduction, development and inheritance. Today, we will learn "the reproduction and development of living things" together.
3. Story guidance stimulates interest
In the study of "Inheritance and Variation of Biology", I told an anecdote about Einstein: American dancing female stars rejected the pursuit of many romantic and handsome sons and brothers, but wrote letters to Einstein, an ordinary-looking, unkempt scientist, for courtship. She wrote: "If we get married, I believe our descendants will be as smart as you and as beautiful as me." Students can't help thinking: If she really gets married, can her dream come true? Through the story situation, students' interest in inquiry can be stimulated.
Second, independent inquiry, let students "walk"
In biology classroom teaching, using inquiry mode to organize teaching activities can really make students' hands and brains move together, stimulate students' interest in learning biology knowledge to a great extent, deepen students' impression and stimulate students to think about problems, thus improving classroom teaching efficiency. From the social phenomena, natural phenomena and daily life that students are familiar with or interested in, some problems with scientific research value are revealed for students to analyze and solve, so as to arouse students' cognitive needs and make them have a strong thirst for knowledge.
Third, link the media, so that students "feel" moved
1. Dynamic vision
Multimedia can turn static into dynamic, virtual into reality and abstract into intuitive; Broaden and deepen the connotation and extension of classroom learning. In traditional teaching, the teaching content is presented by blackboard and chalk, and then dictated by the teacher, which is monotonous and boring. Multimedia technology, by playing pictures, animations, etc. , so that students' senses are most directly impacted, thus stimulating students' interest in learning, making students truly become the main body of learning and promoting their positive development.
2. Inner touch
For example, at the end of the lesson on reproductive development of amphibians, I encouraged students like this: "As middle school students, we should not only protect the environment from ourselves, but also educate people around us to care for the environment and our common home. We firmly believe that as long as everyone gives a little love, the world's tomorrow will be better. "We call on everyone to protect the environment and protect our home together.
In a word, in teaching, we teachers should design colorful activities to guide students to actively use their eyes, mouth and brain, activate a variety of senses in the activities, gain direct experience, let students think independently in practice and experience, and improve their ability to solve problems. Only in this way can we stimulate students' interest in learning, cultivate students' desire and ability to operate, and let students learn biology from the heart. This is just like Teacher Liu Xia, a biology researcher at Dalian Institute of Education, often tells us that "biology class should let students start with happiness and stop with wisdom", so that students can study easily, enjoy learning and love learning.
