Creating Biology Teaching in Junior High SchoolThe following are some innovative ways of teaching biology in junior high school:
** I. Teaching model innovation **
1. ** Open Teaching **
- Teaching objectives and content: The teaching objectives and content are dynamic and open. Biology courses were updated quickly and needed to be improved continuously. This characteristic was suitable for open teaching. For example, when teaching green plant-related content, students could be brought into nature and experience the differences between green plants in person, so as to fully experience the course content, stimulate learning enthusiasm and initiative, and improve the teaching effect.
2. ** Layered Teaching **
- Take into account the differences between students: Take into account the differences between students in terms of family situation, education, potential, etc., including factors such as knowledge background, IQ, and emotions. The traditional teaching model used a unified spoon-feeding method to teach students in accordance with their aptitude, while the layered teaching method could take care of the individual development of students.
- "Scientific grouping: Students are grouped according to their own knowledge system, ability level, and other factors to minimize the differences between students in the same group. Then, a unified teaching model is used to teach students in the group, respecting the differences between students, helping students build self-confidence and stimulate learning interest.
** 2. Use the smart classroom environment for innovation ("Five-dimensional Integration" teaching model)**
1. ** To improve the quality of preparation and stimulate students 'interest (First Dimension)**
- The teacher used the smart classroom to push the micro-class video to assist in the preparation, and the students asked questions after watching it. Teachers could use data feedback to know whether students were watching microclasses, and they could also understand problems through message boards. Students could also discuss online and form a learning community.
2. ** Construct a life situation and do a good job of introducing it into the classroom (second dimension)**
- The core knowledge of the classroom was integrated into the living situation, breaking through the limitations of time and space in the classroom. For example, life observation tasks related to biological knowledge, such as the "7-Day Observation Diary of Mung Bean Seeds", could be assigned. Students could use the tablet terminal to take photos and upload them. This would help to cultivate academic literacy and allow students to understand core knowledge in their daily lives.
3. ** Enriching classroom activities, teachers and students explore together (Third Dimension)**
- Make use of the smart classroom environment to enrich the forms of interaction, such as answering questions, random roll call, etc. to increase the attention and participation of students in the classroom. During group discussions, the teacher could send a discussion task, and the group would upload the results to the big screen to share. For biological experiments, teachers could display the experimental process through the physical booth of the tablet terminal. For experiments that were difficult to complete in the classroom, they could use the virtual experimental booth to deepen the students 'understanding of knowledge.
4. ** Prompt feedback in class, using learning to stimulate reflection (Fourth Dimension)**
- In the smart classroom environment, the teacher arranged the whole class to answer questions, and the students used the tablet terminal to answer the questions. The teacher grasped the students 'answers in real time through intelligent correction and big data statistics and analysis, so as to better complete the teaching and achieve the course goal.
5. ** To improve the quality of assignments and evaluations (Fifth Dimension)**
- In addition to traditional paper assignments, various forms of assignments could be arranged through the smart classroom environment, such as micro-class review, virtual experiments, activity experience, test questions, handwritten report production, Short videos editing, etc. In the evaluation class, big data was used to analyze the test situation, understand the common mistakes, and carry out targeted explanations. It could also generate a customized study manual to push exercises for students 'weak knowledge points.
** 3. Through project-based learning and project-based learning, innovation **
1. ** Project-based learning **
- For example, in Tianjin City Nancang Middle School, teachers and students used project-based learning mode to carry out experimental research in the fields of tissue culture, water culture, soil culture, and microorganisms. In the process of project research, students had to consult literature, design experiments, draw mind maps, determine experimental processes, analyze experimental data, construct mathematical models, write experimental reports, display results, etc. This helped to improve students 'various abilities, such as observation ability, reading literature ability, experimental operation ability, argumentation ability, analysis problem ability, language expression ability, and also cultivate scientific thinking and scientific research spirit.
2. ** Research-based learning **
- Teachers set up many research learning courses such as "tissue culture of candied dennie","water culture vegetables","water culture flowers","production of microorganisms fertilizer", etc., and self-compiled school-based teaching materials to encourage students to carry out innovative learning and research, provide students with individual and diverse choices, and promote the cultivation of students 'interests, practical ability, and innovative spirit.

Who does the peony symbolize?Peony symbolized many types of people. It symbolized nobility and wealth. Because of its large flowers and bright colors, it had the meaning of wealth and nobility. During the Sui and Tang Dynasties, it was the exclusive flower of the royal family. Peony also symbolized people with pure love. The flowers were mostly white, pink, or red. In the Book of Songs, it was used as a token of love, a symbol of pure love.
Peony also symbolized people who had backbone and were not afraid of power. In the legend of Wu Zetian demoting peonies, peonies were not afraid of power and were punished for failing to bloom on time. This kind of strong bones and unyielding spirit was favored by literati and scholar-bureaucrats. In The Story of Autumn Old Man Encountering Immortals, the peony fairy severely punished the evil slaves who destroyed the flower garden, which also reflected this kind of quality of not fearing power.
At the same time, peony symbolized people with tenacious will and perseverance. Peonies originally grew in the vast mountains. Even if they were not carefully cultivated and cared for, they could still bloom all over the mountains and plains. They could also bloom in poor soil and harsh environments. In modern times, under the situation of shrinking forest area and excessive digging of medicinal herbs, wild peonies still bloomed gorgeous flowers on cliffs or barren and dry plateau.
Peonies could also symbolize people who had a strong yearning for happiness and prosperity. When peonies bloomed, they bloomed like brocade. Their graceful, elegant, rich and peaceful image represented the prosperity and prosperity of the country. People's love for peonies also reflected their yearning for such a beautiful vision.
