Problems in the routine examination of junior high school biology and suggestions
The following problems may exist in the routine examination of junior high school biology and the suggested measures that can be taken: ** 1. Problems ** 1. ** Exams ** - ** Large number of questions **: For example, in the final exam of the second semester of the second year of junior high school, you need to complete 25 multiple-choice questions (a total of 50 points) and 50 small non-multiple-choice questions (a total of 50 points) within 60 minutes. There are a total of 75 questions. The time to answer them is tight. - ** Difficult to differentiate concepts **: Distinguishing the similarities and differences between different species of animals and plants such as mollusks and arthropods is a difficult part of learning and exams. It is easy to confuse concepts and lead to mistakes in answering questions. For example, when determining whether a creature belongs to the taxonomical fish, some names have the word "fish" but are not fish (such as crocodiles, dolphins, squid), while names without "fish" may be fish (such as yellow duck, loach). This is easy to confuse examinees. - ** Confusing **: Some questions test the degree of detail and analytical judgment of the knowledge. For example, the question about the breathing characteristics of pigeons in flight involves the examination of the function of air sacs. Its role in the breathing process is easily misunderstood. 2. ** Experimental teaching ** - ** Incomplete experimental equipment and materials **: Due to the limitations of the objective conditions of the school's laboratory, some experiments arranged in the teaching materials could not be carried out, affecting the ability of students to obtain knowledge through experiments. It also disappointed students because experiments were important to stimulate students 'desire for knowledge. ** II. Suggestion ** 1. ** For exams ** - [Concept learning: Create and use a mind map to distinguish the differences between various concepts. It will help you remember biological concepts, such as distinguishing between different animal and plant concepts.] - ** Answer Skills ** - ** Mark the key words **: Learn to quickly find the key words in the question (the key words). Some questions are very long, but it is easy to find the correct answer after identifying the key words. - ** Carefully and meticulously review the questions **: Answer the questions according to the requirements and pay attention to the special requirements in the questions. For example, you should clearly distinguish whether you need to fill in the structure name or the number in the answer. For the chart questions, you should pay attention to the direction of the arrow. - ** Use scientific language **: Use scientific and rigorous language when answering questions. For example, in biological experiment questions, you must accurately express the experimental conditions. Missing a word may affect the accuracy of the answer. - [Comprehensively consider the problem]: When some questions require mathematical methods to solve biological problems, comprehensive and detailed considerations should be taken into account. For example, when calculating the probability of genetic diseases, a variety of factors should be considered. 2. ** For experimental teaching **: The school should try its best to improve the equipment and materials in the laboratory. Biology teachers should actively carry out effective experimental teaching activities so that students can truly benefit from the experiment. This is because experimental teaching can cultivate students 'ability to combine theory and practice, deepen their understanding of teaching materials, and improve their biological quality. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
