How to engage students in activities in the biology classroom

Let the classroom full of vitality, so that students take the initiative and actively participate in the classroom, is the new curriculum concept requirements, but also since I have been exploring the goal of how to let students in the biology classroom in the whole body and mind to feel the joy of learning biology, the following are some of the measures I have taken in teaching.

One, create a situation, let the students "heart" move

As the saying goes, "a good start is half of success." If we can more ink in the beginning stage of the activities, more brains, so that the creation of teaching activities context-specific, interesting, creative, causing students to learn from the heart to knowledge, activities often play an unexpected effect.

1. The use of news introduction

In the study of "infectious diseases and their prevention" in the first use of news broadcasts in the World Health Organization on the "Influenza A spread to more than 260 countries, resulting in a lot of deaths," the report, so that the student What kind of disease is influenza A? What causes influenza A? Can we be infected?" The students will be able to learn more about infectious diseases, and at the same time, they will be inspired to learn more about infectious diseases.

2. Using songs to introduce

The teacher played the song "Beautiful Grassland My Home" during the class, the music stopped, the teacher asked the students: "Do you know what song you just heard?" Yes, a high-pitched and loud "Beautiful Grassland My Home", let us think of the vibrant scene of all things, and all things in the world can live and breathe generations of reproduction, because they have the basic characteristics of reproduction, development and heredity, today, we come together to learn the "reproduction and development of organisms".

3. Story guide, stimulate interest

In the study of "biological heredity and mutation", I recounted Albert Einstein's escapades: the American dancing starlet refused the pursuit of many of the dashing young men, but wrote a letter to the ordinary-looking, unkempt scientists to court Albert Einstein, she wrote: "If we get married, I am sure our offspring will be as smart as you are and as beautiful as I am." Students can't help but wonder: if they do get married, can her dream come true? Through the story situation, it can stimulate students' interest in inquiry.

Second, independent inquiry, so that students "line"

In biology classroom teaching, using the inquiry mode of organization of teaching activities, really let the students' hands and brains together, can be a greater degree of interest in stirring up students to learn biological knowledge, and deepen the students' impression, stimulate students to think about the problem, and thus improve the efficiency of classroom teaching. This will improve the efficiency of classroom teaching. From the students familiar or interested in social phenomena, natural phenomena and daily life to reveal some of the scientific research value of the problem, let the students to analyze and solve, in order to trigger the cognitive needs of the students, so that they produce a strong desire for knowledge.

Three, link media, so that students "sense"

1. visual sense of movement

Multimedia can be static for movement, virtual for real, abstract for intuitive; broaden and deepen the connotation and extension of classroom learning. In traditional teaching, teaching content is presented through the blackboard and chalk mode, and then through the teacher's oral "full irrigation", which is both monotonous and dull. Multimedia technology through the playback of pictures, animation, etc., so that the students' senses by the most direct impact, thus stimulating students' interest in learning, so that students really become the main body of learning, and promote the active development of students.

2. The inner touch

For example, in the study of amphibian reproductive development of a section of the end of the lesson, I am so motivated students: "As secondary school students we not only want to start from their own to protect the environment, but also to educate the people around us to come to care for the environment, care for our *** with the home. We firmly believe that as long as everyone gives a little love, the world will be a better tomorrow", calling on everyone to come together to protect the environment and protect our homes.

In short, in teaching, we teachers should design colorful activities to guide students to actively use their eyes, mouth, brain, in the activities to start a variety of senses to obtain direct experience, so that students in the practice and experience of independent thinking, to improve problem-solving skills. Only in this way can we stimulate students' interest in learning, cultivate their desire to do it and their ability to operate, and make them learn biology from the bottom of their hearts. This is like the Dalian Institute of Education, biology teacher and researcher Ms. Liu Xia often say to us, "Let the students in the biology classroom, starting from happiness, ending in wisdom," so that students learn easily, enjoy learning, love learning.
