First, cultivate students' scientific inquiry ability.
Scientific inquiry ability includes understanding the relationship between science, technology and society, understanding the nature of science, and forming scientific attitudes and values. In biology teaching, students should not only master certain biological knowledge, but also cultivate good scientific quality, scientific attitude, scientific spirit, correct scientific outlook and scientific ability.
A correct understanding of knowledge is a scientific belief and habit formed by the understanding of scientific development. Every student is a natural "scientist". They are naturally curious about the world around them, especially those creatures in nature. They are passionate about all kinds of life phenomena in nature since childhood, and they can feel full and excited in the process of exploring nature. The task of biology teachers is to cultivate students' curiosity about science, and keep this curiosity, so that it can be further transformed into a correct attitude towards science and learning science. Therefore, students should be encouraged to talk more in classroom teaching and be given appropriate evaluation in time; Try to answer students' questions positively, and if you can't answer them, tell them the way to get the answer.
Inquiry learning refers to the learning way that students acquire and use knowledge through personal experience in an open real life situation in a way similar to scientific research. Inquiry learning is an important way of learning in biology teaching. Through the research and implementation of inquiry topics, it is of great significance to strengthen the cultivation of students' scientific inquiry ability and effectively improve students' scientific literacy for cultivating students' innovative spirit and practical ability.
1, guide students to explore independently. Traditional teaching knowledge is large and involves a wide range, which seriously squeezes students' independent learning and active inquiry learning methods, which is not conducive to the cultivation of students' scientific inquiry ability. Without scientific inquiry, there is no scientific literacy. Scientific literacy cannot rely solely on the inheritance of knowledge, and the formation of teaching indoctrination must be changed. In other words, we should change passive listening into active learning and independent inquiry. For example, in a classroom that bears fruit, teachers can let students assemble their own flower structure diagrams, acquire new knowledge, analyze and solve problems in the process of active learning and independent inquiry, and make students' learning process personalized.
2. Let students know that the general process of scientific inquiry begins with finding and asking questions. After asking a question, you can try to make assumptions about the answer to this question according to your existing knowledge and life experience. Then design the inquiry scheme, including the selection of materials, design methods and steps. Explore according to the exploration plan, get the results, and then analyze whether the results are consistent with the assumptions, so as to draw a conclusion. Cultivate students' scientific inquiry ability. In the process of inquiry, how teachers guide students to develop their thinking and imagination is the key. Guiding questions and cultivating students to find, ask and explore questions are the starting points for teachers to guide teaching. Einstein said, "It is more important to ask a question than to solve it". For example, in the exploratory experiment of "light has an impact on the life of the mouse wife", teachers can start with students catching the mouse wife and guide students to find out the problem through observation and personal experience: why did the mouse wife run away? Are you scared? Are you afraid of light? Or do you prefer to be in a humid environment? This is the premise and key of scientific inquiry. Then the query process can proceed smoothly. Through inquiry, students not only acquire the cultivation of scientific inquiry ability. At the same time, it improves and cultivates the cultivation and development of scientific inquiry.
3. Pay attention to biological science experiments. Biological science experiments can make us develop in an all-round way in knowledge, ability, emotion, attitude and values. By actively participating in and experiencing various inquiry activities, we can improve our observation ability, experimental ability and thinking ability. Innovative spirit and practical ability. It is the breakthrough point and breakthrough point to realize the change of methodology and an important means to learn biological knowledge well. It is also an indispensable and important means in inquiry learning. It is also an important way to cultivate students' biological abilities such as innovation ability. It plays an irreplaceable role in promoting the cultivation of young people's scientific literacy and the formation of their quality.
Of course, scientific inquiry is a multifaceted activity, and it has a relatively complete scientific inquiry activity. There are also some activities for students to participate in scientific inquiry. The methods of inquiry are flexible and diverse, including experimental methods, observation, investigation and measurement methods, which I need to analyze and solve with scientific methods in my future study.
Second, cultivate students' innovative spirit and practical ability.
Quality education focuses on cultivating students' innovative spirit and practical ability, which are the basis of scientific literacy. Good teaching methods can awaken students' innovative consciousness, and at the same time make students feel that they can't just rely on teachers to explain in class. More importantly, they should think independently and use their brains actively to understand under the guidance of teachers. In order to understand the process of knowledge generation and development, it is necessary to:
1, pay attention to cultivating students' observation ability. Observation is the information channel, the door of thinking exploration, and keen observation is the initiator of innovative thinking. It can be said that without observation, there is no discovery, let alone creation. We all know the discovery of bacteria. Without Levin Hooke's keen insight and analytical power, there would be no Pasteur's theory of bacterial spontaneous occurrence and his contribution to the prevention and treatment of human diseases.
2. Pay attention to cultivating students' imagination. Imagination is the wing of thinking exploration. For example, in the course of observing the structure of plant cells, students can show their imagination, innovation and practical ability after observing plant cells, and their imagination is particularly rich. Some students use plastic foam as the cytoplasm of plant cells, some students use plastic shells as the cell walls of plant cells, some students use ripe bananas as vacuoles, some students use chocolate as the nucleus, and some students use mung beans. A complete model of plant cell structure is clearly presented to us. Students use observation, hands-on and imagination. Mastered the knowledge points. Cultivate the success and pleasure of "creation".
Students' spirit of innovation and difference is an indispensable quality of innovative talents and the basis of scientific literacy, which we should encourage and carry forward.
Third, guide students to pay attention to the new progress of science and technology and social education.
Socialization of science and technology and scientization of society have become one of the hot spots in social life today. Understand the relationship between science, technology and society, pay attention to and participate in the discussion and decision-making of social issues related to biotechnology. It is an important part of biological science literacy and an important way to cultivate students' sense of responsibility for nature and society. Understand the "stories of scientists", "social ethics issues", "occupations related to biology" and so on. The purpose is to let students know the development course and progress of life science. Understand the work of scientists, their tenacious and realistic scientific attitude, and the application of biotechnology in various fields of society and some problems brought about by the application of science and technology. For example, Yuan Longping, the father of China scientist hybrid rice, achieved a real breakthrough in rice breeding. It has brought great economic and social benefits to social and economic production, not only solved the problem of eating in China, but also made greater contributions to solving the hunger problem faced by mankind. Through the understanding of science and technology society, it plays an irreplaceable role in promoting the cultivation of young people's scientific literacy and the formation of modern people's quality Review the thinking process of scientific research and learn from scientists' tenacious and realistic scientific attitude. As well as the application of biotechnology in various fields of society and some problems brought about by the application of science and technology, so as to promote the healthy development of students' emotions, attitudes and values.
It is an organic whole to improve the literacy of biological science and advocate inquiry learning for all junior high school students, which is not only the concept of curriculum and teaching curriculum reform, but also the basic concept to guide teaching implementation. We can use it to standardize our teaching behavior and enlighten our infinite teaching wisdom.
