Anonymous users2024-02-12Biology is an experimental science, observation and experiment is the basic method of learning biological science, and it is the responsibility of biology teachers to strive to create conditions, combine students' psychological and physiological characteristics, overcome difficulties, complete classroom experimental teaching stipulated in curriculum standards and textbooks, cultivate students' ability, develop intelligence, improve students' quality, and improve the quality of biology teaching. According to the curriculum standards and plan, the following summary of the teaching of biological experiments will be made for the completion of laboratory courses as required in this semester:
1. Clarify the purpose of the experiment and stimulate students' motivation to learn
Psychology tells us that purpose is the result of a person's action, and motivation is the motivation that motivates a person to act. If students clarify the purpose of the experiment and consciously generate the internal motivation of the experiment, the experiment will be effective. But the students are curious, active, and unfamiliar with experiments.
Some students think that taking experimental classes is fun and lack scientific attitude, and some students think that they do not take the examination and the purpose of learning is not clear, which brings certain difficulties to the organization and teaching of experimental courses. Therefore, before the experiment, students are not only required to clarify the purpose of the experiment in the textbook, but also to clarify the practical application of the experiment in production and life.
2. Instruct students to master the methods of experimental procedures and standardize operations
The experimental steps are the essentials of the students' hands-on standardized operation, and only by understanding and mastering can the standardized operation be standardized and the experiment can be successful. Therefore, before the experiment, students should be instructed to prepare, simplify the experimental steps from complex, and grasp the key words of each step to collude in the experimental steps to obtain good experimental results.
3. Instruct students to observe experimental phenomena
Students' standardized operation in the process of the experiment is the basis of the experiment, and the careful observation of the experimental phenomenon is the key to achieve the purpose of the experiment and explore the experimental results. However, students often pay attention to operation in experiments, ignoring observation and analysis. Through students' hands-on, eye-moving, brain-moving, observation, and analytical thinking, students' serious scientific attitude, mastery of knowledge, and improvement of ability are cultivated.
Fourth, the textbook requirements are mastered, and the difficult experiments are examined
Through experimental examination, students are encouraged to carefully preview, review, and operate. Students with poor experimental operation should be found in time, and individual counseling should be strengthened to ensure that everyone passes the test. In this way, the contradiction of few experimental instruments, many students, and difficult to do is overcome and students' interest in learning biology is improved.
To sum up, through experimental teaching, students are cultivated to learn the basic methods of biological science, serious scientific attitude, develop intelligence, improve their interest in learning biology, and thus improve the quality of biology teaching.

Consumers are not able to produce food directly from solar energy, but can only obtain energy directly or indirectly from the diet of green plants. Bacillus anthracis cannot use light energy to convert into its own organic energy like plants all the time, nor can it use inorganic chemical energy to convert into its own energy like autotrophic bacteria, so it is not a producer. And it can't decompose organic waste into inorganic matter like some bacteria, and it can't act as a "scavenger" of the ecosphere to connect the organic environment and the inorganic environment. >>>More
The simplest: transpiration of plants.
Put a plastic bag around the base of a plant's stem (note that it must be the base of the stem), place it in the dark, and just wait. After a while, you will notice that there are small water droplets in the plastic bag. These are the water droplets formed by the water vapor emitted by the transpiration of the plant. >>>More
Plants have chlorophyll, no nerves, no sensations.
Animals, on the other hand, have nerves and sensations. It feeds on organic matter (plants, animals or microorganisms) for life activities such as feeding, digestion, absorption, respiration, circulation, excretion, sensation, movement and reproduction. >>>More
I'll come, it's a piece of cake.
The vascular output per minute of the heart chamber is the same, and the output per minute is the cardiac output; Item B is clearly wrong; C, the blood pressure is absolutely different, the cardiac artery is greater than the venous blood pressure because the transportation route is longer, and the aorta is greater than the pulmonary vein blood pressure because the aorta is transported to the whole body, while the pulmonary artery is only transported to the lungs to the heart; Circulatory pressure should be left until blood pressure is too high for a long time]. >>>More
