Is cross-examination biology teaching difficult?
The cross-examination biology teaching theory had a certain degree of difficulty. First of all, from the content of the exam, most schools 'biology entrance exams tested two professional courses, the second of which was mostly general biology or biology teaching theory. Biology teaching theory was mainly based on theoretical knowledge, and it required a deep understanding and mastery of theoretical knowledge related to biology teaching. Secondly, from the admission situation, for example, the average admission score of the subject teaching (biology) major of South China Normal University has been 400 + in the past two years. The score requirement is very high, reflecting the intensity of competition. Moreover, the education major had become more and more difficult in the past two years, and the competition was very high. However, if the undergraduate course was a biology-related major, such as bioengineering, it might be relatively easy to understand the knowledge related to biology teaching theory due to a certain foundation of biological knowledge. However, it was still necessary to overcome the challenges of thinking from biological professional knowledge to teaching theory and methods. Read more exciting novels for free
Henan University biology cross-examination
There was no direct mention of the biology exam at Henan University, but some general reference content could be obtained from other biology related information. The competition for the postgraduate entrance examination was becoming increasingly fierce. If it was biology, the foundation might be relatively weak. If he had the ability, he could consider applying for a class. There were many benefits to signing up for a class. For example, there was no need to worry too much about collecting information, and there were seniors to lead the way, so there were fewer detours. At the same time, he had to buy the textbooks and the corresponding problem sets from the reference catalog. During the preparation process, he had to ensure that he had enough time to study and review at his own pace. He did not have to compare his progress with others, but he had to be aware of it. However, it should be noted that this was only a reference suggestion given based on the situation of other biology exams. There may be special requirements or precautions for Henan University's biology cross-examination that were not mentioned. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the Teaching of the New College Entrance Examination of Biology
The following are some of the main points of reflection on the new biology college entrance examination: ** 1. Teaching strategy adjustment ** 1. ** Balance between practice and exam ** - It was found that the students 'mastery of knowledge was related to the teaching method. For example, sometimes the effect of a teacher's lecture was not as good as the students 'extra-cursory practice, and the effect of extra-cursory practice was not as good as the results of the exam. Based on this, he could use the method of teaching less and practicing more in class, doing less and taking more tests outside the class. For example, in order to improve the students 'ability to solve multiple-choice questions, the lesson preparation team would give the students one-to-two exams every week (about 10 questions each time) for several consecutive weeks. They would also give feedback and praise the students who scored high and made great progress. 2. ** Homework grading and topic selection ** - Some assignments could be approved less (but they still had to check if the students had completed them) and let the students mark them themselves. The teachers would spend more time on choosing topics and share all the materials in the lesson preparation team to improve the efficiency of the use of teaching resources. 3. ** Evaluation Method ** - They could use the method of letting the students do the questions first, and then the students would raise the questions before giving a unified evaluation. Although this would increase the workload of the teachers, it would save time for the students and help improve their grades. ** 2. Review Stage ** 1. ** Second round of revision ** - Focus on solving the problem of knowledge integration, induction, and reasoning ability cultivation, and construct a complete biological knowledge system to adapt to the college entrance examination. - There were two aspects to consider when choosing a review topic. One was the cross-chapter topic within the subject, such as the "plant metabolism and regulation" topic, which involved the compulsory book of plant biology and regulation, and the second chapter of the elective book. This method helped to straighten out the scattered knowledge points in the first round of review and establish a complete knowledge system. Secondly, based on a certain knowledge point, the relevant cross-chapter knowledge would be summarized together, such as protein topics, bioenergy topics, biological breeding topics, innovative experimental design and analysis topics, etc. This was very effective in cultivating students 'ability to transfer knowledge and analyze specific processes. - The choice of exercises was crucial to improving students 'scoring ability. As the comprehensive science test arranged by the school would take up class time, if the practice questions were too much, it would affect the analysis of the topic. Therefore, according to the analysis of the first round of revision of the middle school students 'answers, according to the characteristics of the college entrance examination questions over the years, the selection and re-editing of the practice questions would be carried out. - In the final stage after the second round of review, teachers and students had to walk out of the comprehensive simulation questions. The students returned to the teaching materials, found the "wrong questions" in the test papers that they had done, and checked for any gaps. The teacher guided them in class and focused on explaining the common problems that the students had. Generally, they would not conduct a unified test. ** 3. Teaching content and cultivation ** 1. ** Teaching objectives and core accomplishments ** - In the context of the new college entrance examination, high school biology teaching should be based on the development of students 'core qualities, including the concept of life, scientific thinking, scientific inquiry, and social responsibility. Teachers should take these as the overall goal when carrying out classroom teaching. For example, the teaching design of the section on active transport in the compulsory textbook could be determined as: from the perspective of life, it was necessary to give examples of some substances entering and leaving the cell against the concentration grade; from the perspective of scientific thinking and scientific inquiry, it was necessary to analyze the characteristics of carrier protein by observing the active transport process; from the perspective of social responsibility, it was necessary to explain the significance of active transport. 2. ** Knowledge System Construction ** - Biology was a science subject, and classroom teaching should be "reasonable." Students should understand the ins and outs of knowledge and the causality between life events. From there, they could clarify the internal connection of knowledge and build a more solid knowledge system. For example, when explaining the influencing factors of active transport, the students should be guided to analyze why the O2 concentration would affect active transport (active transport requires the consumption of energy produced by cell metabolism → the energy required for life activities is provided by cell breathing → the main way of cell breathing is oxygen breathing → the oxygen breathing process requires the consumption of O2→ the O2 concentration will affect oxygen breathing, thus affecting active transport). Another example was the teaching of the structure and function of cell membranes. The new textbook added the exploration process of cell membrane composition and structure. Teachers could guide students to re-explore the path of scientists and clarify the composition and structure of cell membranes. 3. ** The use of teaching situations ** - We should use the teaching situation to improve quality and efficiency. The sources of materials for teaching situations were diverse, such as common phenomena in production and life, classroom demonstration experiments, life science history, new scientific progress, social hot spots, etc. The forms included life situations, imagination situations, simulation situations, experimental situations, etc. However, no matter what kind of situation it was, it should be question-oriented. By discovering and solving problems, it could stimulate the students 'thinking and develop their accomplishments. For example, in the teaching of active transport, the latest progress in the study of glucose carriers could be used to introduce the exploration of the mode of glucose transport, and it could be proposed that the absorption of glucose by the small intestine membrane was an active transport, so as to carry out the new lesson. The reabsorption of urine could also be used as an example to analyze the way of reabsorption of different substances. The method of absorbing iodinated ions by the fetal Follicular Epidermal Cell in the textbook "Question Discussion" could also be used as an example to guide the students to think. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the Teaching of Biology Academic Level Examination Experiment
The following are some reflections on the biology academic level test experiment: ** 1. Experiment preparation ** 1. sufficiency - For the experiment teaching in the biology level examination, the experimental preparation directly affects the teaching effect. When preparing for the experiment, it was necessary to plan the details such as the amount of equipment and materials needed for the experiment in advance, just like what was reflected in the Weihai City High School Biology Examination. For example, in microscope-related experiments, it was necessary to ensure that the number of microscopes was sufficient and that they could be used normally. There were also sufficient materials such as slide specimens. If the preparation was insufficient, it might lead to a shortage of equipment and materials during the experiment, affecting the students 'experimental operation process and mastery of knowledge. 2. targeted - He had to prepare the experiment content according to the requirements of the academic level test. As the exam involved multiple experiments in the textbooks from Grade One to Grade Three, each experiment needed to be analyzed in depth to clarify the key points. For example, experiments based on the use of the microscope accounted for a large proportion. In the preparation process, it was necessary to focus on the knowledge points related to the operation of the microscope, such as how to adjust the focal length, how to observe the specimen, etc., so that the students could be guided to master these key skills in the teaching. ** 2. Teaching process ** 1. student's main position - In the teaching of biological experiments, students should play a major role. It could not just be a demonstration by the teacher and the students watching. Instead, the students had to do it themselves. For example, in the experiment of the academic level examination, like the biological experiment operation assessment, the students were allowed to operate independently and accept the evaluation of the teacher. However, in actual teaching, there might be situations where teachers gave excessive guidance and students lacked independent thinking and operation. Under the premise of ensuring safety and experimental standards, teachers should give students more space for independent exploration, so that they could discover and solve problems in the experiment, thereby improving their experimental quality. 2. teaching method - For complex experiments, such as the use of a microscope, appropriate teaching methods were needed. For junior high school students, the use of a microscope was more complicated, and a single explanation might not be effective. He could use a step-by-step teaching method. First, he would explain the theory, then give a simple demonstration. Then, he would let the students operate step by step, from easy to difficult. At the same time, teaching resources such as micro-videos could be used, just like the micro-videos produced by the teachers of various schools in Weihai City, to show the details of the experiment and help students better understand the experimental steps and scoring standards. 3. time management - Time management was also an important aspect in experimental teaching. The time for each experiment should be arranged reasonably to avoid situations where the students waited for a long time. When designing the experimental teaching, it was necessary to estimate the time required for each link according to the difficulty of the experiment and the speed of the students 'operation to ensure that the entire experimental teaching process was compact and orderly. ** 3. Teacher's Quality ** 1. expertise - Teachers 'own professional knowledge reserves must be constantly updated and improved. The experimental content of the biology academic level test may change with the update of the curriculum standards. Teachers need to keep up with the latest test requirements and experimental content. For example, new experimental techniques or new explanations of existing experiments might be introduced in experimental teaching. Only teachers with solid professional knowledge could accurately impart them to students. 2. experimental skills - Teachers also needed to improve their experimental skills. In some experiments, the teacher might be in contact with it for the first time or might not be familiar with the operation. This required the teacher to practice more before class to ensure that he could skillfully demonstrate during the teaching process and accurately answer the operational problems encountered by the students during the experiment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the most difficult biology questions in the college entrance examination?
The difficult questions in high school biology were roughly the following: 1. * * Calculation questions related to protein **: - It involved the calculation of the relationship between the number of peptidic bonds, the number of water molecules removed, the number of ammo acid molecules, and the number of peptidic chains of the protein. For example, the number of peptidic bonds in a protein was equal to the number of water molecules removed, which was equal to the number of acid molecules minus the number of peptidic chains. The number of water molecules required for complete digestion of a protein was equal to the number of water molecules removed during the formation of the protein. - The calculation of the minimum number of amine groups and starch groups in a protein, the number of which is at least equal to the number of protein chains. - To calculate the relative molecular mass of a protein, one needed to consider the average relative molecular mass of the protein, the number of the protein, and the number of water molecules removed. In other words, the relative molecular mass of a protein was equal to the average relative molecular mass of the protein multiplied by the number of the protein minus 18 multiplied by the number of water molecules removed. There were also calculations related to the ratio of the number of bases in genes, messenger R A bases, and the number of aa in the protein. 2. * * The calculation of the number of layers of biological membranes: - It was necessary to clarify the number of membrane layers in different cell structures. For example, one biological membrane was equal to one layer of the Phospholide bilayers, which was equal to two layers of the Phospholide bilayers; Ribosome, Centrosome, and Chromosome had no membrane structure; Cell membrane, tonosome membrane, plasmatic membrane membrane, and Golgi membrane were single membranes; The membranes of mitochondria, chlorites, and the nucleus were double membranes (the number of membrane layers that substances passed through the nuclear membrane from the nuclear pore was zero). - For structures such as the walls of the lungs, capillaries, and digestive tract, which were composed of a single layer of cultured cells, passing through one layer of cells required passing through two cell membranes (biological membranes) or four layers of Phospholide molecules. 3. * * Calculation problems related to photosynthesis and breathing **: - According to the relationship between the raw materials and the products in the reaction formula, the chemical calculation was carried out. For example, the mole ratio of carbon dioxide produced by the two processes was 1:3 when the same amount of glucose was consumed, and the mole ratio of glucose consumed by the two processes was 3:1 when the same amount of carbon dioxide was released. - For green plants, it is necessary to distinguish between the net photosynthesis rate measured under light and the actual photosynthesis rate.(The actual photosynthesis rate is equal to the net photosynthesis rate plus the respiratory rate), which involves the calculation of the actual oxygen production of photosynthesis (equal to the measured oxygen release plus the oxygen absorption and consumption of the respiratory rate), the actual carbon dioxide consumption of photosynthesis (equal to the measured carbon dioxide consumption plus the carbon dioxide release of the respiratory rate), and the net production of glucose by photosynthesis (equal to the actual production of glucose by photosynthesis minus the consumption of glucose by the respiratory rate). In addition, for organisms such as yeast that could produce both oxygen and oxygen and produce CO2, it was necessary to calculate the type of breathing based on the volume ratio of the released CO2 to the absorbed O2. 4. * * Experimental design questions **: For example, National Volume A required the design of an experimental plan to verify that protein fragments could appear in the lysomes of engulfing cells; the new curriculum standard volume required the design of an experimental plan to detect the AIDS virus in blood samples, etc. These questions tested the students 'ability to use basic experimental methods and techniques to solve new problems, including designing experimental plans, optimization of experimental procedures, and analysis of experimental results. 5. "Genetics related topics: For example, the new curriculum standard paper mentioned that white thorn melons were favored by consumers, and practical problems in the production and breeding of fruit and vegetable crops with high yield of female plants. It required the use of genetic crossing methods to screen out the pure body of white thorn female plants. 6. * * Big topics related to ecology **: For example, the new curriculum standard volume took Yundan Lake in Xiameng as the theme, examining the reasons for monitoring nitrogen in water quality assessment, the physiological process of carbon neutrality of mangroves, the key role of birds and other consumers in the ecosystem, etc. National Volume A took the protection of endangered species B as an example, showing the discovery of a small number of wild individuals during the protection process, artificial breeding, release in the wild, and gradually expanding the population. This type of question tested ecological knowledge and incorporated some guidance from ideas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is geography or biology more difficult in the new college entrance examination?
There was no absolute answer to which subject was more difficult in the new college entrance examination, geography or biology. The difficulty varied due to many factors. In terms of learning difficulty, biology required students to have strong logical thinking and experimental operation ability, and had a higher requirement for understanding abstract concepts and phenomena. The study of geography required students to have a strong memory and spatial thinking ability. For example, the knowledge system of climate, geomorphology, and topography in natural geography was huge and complex. Moreover, geography emphasized the combination of theory and practice, and theoretical knowledge needed to be applied to real life. This required students to have a high practical ability. From this perspective, geography seemed to be more difficult. From the point of view of the difficulty of scoring, the difficulty of scoring chemistry was slightly higher than biology, and the difficulty of scoring biology was stronger than that of geography. Under the binding of materialization, students with strong science thinking tended to choose biology, and the overall level of students who chose biology was higher. This might make the competition for biology more intense. From the perspective of students 'thinking advantage, students with good rational thinking might find geography easy, while students with good memory might find biology easy. Moreover, if the major that the student wanted to apply for in the future was medicine, pharmacy, and other science and engineering subjects that required biology, it would be more advantageous to choose biology. Except for specific majors such as geography, most majors did not require geography. In general, both subjects had a certain degree of difficulty, and it varied from person to person. Different learning abilities, hobbies, and future professional plans would affect the judgment of the difficulty of these two subjects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A school with a low difficulty in subject teaching and biology entrance examination
Generally speaking, second-tier universities were relatively easier to take the postgraduate entrance examination in biology. They just needed to get a national score, followed by first-tier universities, 211 universities, and 985 universities. Jiangnan University's fermentation major was very strong, and it also had certain advantages in biology. The postgraduate entrance examination might be relatively less difficult. In addition, apart from popular majors such as Ma Theory and subject teaching, the other majors in Yanbian University followed the national line of Zone B. The re-enrollment ratio was very low. Many of them were 1:1 equal admission, which was relatively friendly. However, the specific difficulty of the postgraduate entrance examination was also affected by many factors, such as the number of students enrolled, the popularity of the application, etc. For example, South China Normal University had a large number of students enrolled in the subject teaching biology major, but the score requirement was high. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it difficult to take the postgraduate entrance examination for the biology major of jilin university
The overall difficulty of the postgraduate entrance examination for the biology major of the University of Ji Lin was not particularly high. The postgraduate entrance exam generally did not test mathematics, and there were real questions. It was a science subject with fixed answers, which reduced the difficulty of preparing for the exam to a certain extent. The national standard for science majors was relatively low, and the number of students enrolled was relatively high and stable. However, the overall cut-off point for the students of the University of Ji Lin was on the high side. For biology major students, in addition to the total score, there were also requirements for individual subject scores. They needed to pass 90 (professional courses) and 45 (public courses). They also required the students to not have serious partial subjects. Otherwise, they would not be admitted, nor could they make an exception. Each year, more than 30 people were admitted, and the total number of people recruited was about 45. The second round of the second round was a difference of about 60:45. In terms of preparing for the professional course, the biochemistry reference book was Wang Jingyan's Biochemistry, fourth edition. The reference book for microorganisms was Shen Ping's Microbiology and the corresponding problem sets. As it was an independent proposition, you could collect the real questions and organize the review materials yourself. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is it difficult to take the cross-disciplinary biology major in Chongqing Normal University?
From the following aspects, we can see the difficulty of cross-disciplinary biology major in Chongqing Normal University: - ** Re-examination line and competition **: This major has adopted the national line for the re-examination line for three consecutive years, so the re-examination threshold is relatively low. In the past two years, the re-examination ratio is about 1:1, and the competition for the re-examination is relatively small. - ** In terms of admission score **: From the admission score, the difference between the highest score and the lowest score is quite large. Generally, there is no sign of the score being suppressed. In the past two years, the average score of admission is 360 +. It is more confident to set the score at around 365. - ** Exam subjects **: - ** Initial exam subjects **: Including 101 Political Theory, 204 English (2), 333 Education Integration, 834 Biology Teaching Theory. The 333 Education Comprehensive Bibliography included "Basics of Education"(third edition),"History of China Education"(fourth edition),"History of Foreign Education"(second edition), and "Educational Psychology"(third edition). The 834 Biology Teaching Theory Bibliography was "Secondary School Biology Teaching Theory"(second edition). The new edition was also very important. The exam would add a lot of biological knowledge to the assessment, so it was necessary to supplement the high school biology textbook knowledge. - ** Exam preparation experience **: - **333 Education Integration **: If you study with Kaicheng's basic and intensive classes, you need to supplement your foundation and teaching heart (these two subjects are the most tested). Foreign teacher history and Chinese teacher history can follow Kaicheng. The basic classes don't need to take notes themselves. You can buy a powerpoint frame to memorize later. - **834 Biology Teaching Theory **: The designated book and the new version of the content must be combined to understand and memorize, and the necessary biological knowledge must be supplemented. In general, for cross-examination candidates, if they could prepare well for the initial examination subject and meet the corresponding score requirements, they would also have a certain degree of competitiveness in the second examination. There was a greater chance of success in cross-examination. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
