Rural junior high school biology experiment on the teaching of the cultivation of interest in learning networks _ Papers

Paper net: Interest is the best teacher, is the direct driving force students to learn, therefore, students interested in is the bounden duty of each teacher. Junior high school biology students to quality education is one of the important basic course. Biology itself the experiment, strong discipline, a lot of knowledge come through experiments experiment in biology teaching ability has a pivotal role. determine the characteristics of biological disciplines observation, experiment, explore not only the biological basis for teaching, and but also to develop interest in learning so that students take the initiative to acquire knowledge, develop capacity, improve the scientific quality of the basic approach by experiments in the biological process of teaching to stimulate students interest in learning to develop students ability to learn, so that students understand that learning biological sciences, not just is to meet the test, but to understand themselves and the living environment, explain and solve problems in life. cultivate biological literacy, learning and even careers for the future and lay a solid foundation.

Junior secondary level, especially students who started, interest is the first important, and only had a strong interest in learning, students will want to learn, to learn, love of learning in everyday teaching how to improve the quality of teaching of biological experiments in order to stimulate student interest in learning? can try the following aspects.

First, the creation of experimental conditions
1 well located the suspect, to stimulate interest in learning
The so-called setting the problem situation is familiar from the student or interested in the phenomenon of everyday life and reveal some scientific value problems for students to analyze and solve in order to lead students to have a strong thirst for knowledge.

For example, stresses "the role of stem ease" in this section, it can be a demonstration experiment, take A, B two test tubes, were added to the same amount of dilution of the red pen water two test tubes were placed upright and inverted two celery, including a cut inverted tail of celery leaves, exposing part of the stem, the roots up into the tube. standing for some time, longitudinal and cross-section of celery stalk observed after in vitro A Upright red celery stalk, and it is the transport of water dilution of the red pen; B diluted in vitro exposure of celery only red pen at the bottom of a thin layer of water was stained. students are very surprised: two in vitro are celery , placed in a different direction just why there are two different phenomena? What does this mean? this series of questions so that students have a strong curiosity, enthusiasm for learning are mobilized, so as to explain "the role of the stem to divert and stem structure, water transport direction, "laid the foundation for this series of experiments.

2. Anything easy to stimulate interest in learning
Some biological knowledge more difficult to understand, explain or blunt futile by rote, or is invalid. Will be difficult to understand how biological knowledge with the most simple, intuitive way for students to understand? Rural life Some well-known in a lot of life experience or experiments on the biological aspects of a simple and thought-provoking, fascinating role, if teachers in the classroom will be difficult to understand the proper use of knowledge expressed in a simple experimental conditions, is able to attract students, lively atmosphere, this theory with practical teaching methods better.

Talking about the game, a lot of people think just play Lele, in fact, is not the case, such as talking about the essential difference between humans and animals, the author of this design: a teacher on the blackboard to write simple words, which comprehend a student on the blackboard for the blackboard meaning of this sentence, then moves back to the blackboard to indicate several other students, several students expressed the results of which are not the same, thus proving the important features of human language which gave us a lot of instructional design inspiration, the game students to stimulate thinking and improve understanding of the student from participation in hands-on brain, from a pleasant and harmonious atmosphere in the classroom are learning is a fun, feel the importance of language learning, so interest in learning multiplication.

Second, the innovative experimental material
Series of experimental teaching green plants, the experimental more cumbersome materials, experimental season and other issues, according to the teaching requirements, able to fulfill the individual experiments, such as observation of flower structure, the use of students to develop cutting edge of potted geranium experiment silver material, with on the part of the experimental teaching, saving the cost to develop the students hands-on mental and physical ability, emotional care of plants, allowing students a real understanding of plant growth and development process, with good results.

Third, to improve the experimental methods
1 change demonstration experiment for the experimental group, the experimental group to explore the experimental change
The teaching of creation in the test conditions, as the teacher's demonstration experiment into the experimental group of students, this will better enable students to do experiments, there are more opportunities to reach out experiments, students of experimental interest.

2 change experiments for the interest group to explore after-school experiment
Some experiments take longer time to explore, not easy to directly access the experimental results, therefore, some teachers give up experiments to explore, or simply talk about experiments lead students to lose interest in learning such as observation of ant communication, to explore the life of light on the impact of Armadillidium so, the premise of scientific guidance of teachers under the condition, can be completed by the students after school so students develop interest in learning, but also to complete the learning task.

3 experiments to explore the place of validation experiments
Demonstration experiments in the conventional textbook and student groups through repeated experiments are verified, these arrangements are often in the concept of the experiment, the theory of dependent status, the interest of students will gradually disappear, so teachers should try to explore the validation experiments experiments.

In summary, in biological experiments teaching, teachers should carefully organize, identify the best students interested in the trigger point, make the best use, so that students interested in the experiment so that students experience the joy of success to inspire students to be more active, more widespread interest in learning.
