Reflection on the experimental teaching plan of the bridge bearing weightThe following is a reflection on a weight-bearing bridge experiment lesson plan:
** 1. Experiment objective **
1. ** Target Achievement Status **
- If the goal was to let the students understand the load capacity of different structural bridges, then from the experimental results, whether the students really understood this concept. For example, in the paper bridge load bearing experiment, whether the student could accurately describe the reason for the difference in load bearing of the paper bridge with different folding methods. If not, it might be that the target setting did not estimate the student's existing knowledge and understanding ability.
- Whether or not sufficient guidance and emphasis were given to the goal of guiding children to try to record the experimental process with drawings or symbols. If the student's records were messy or did not understand the meaning of the records, it meant that there was a lack of effective guidance in the process of implementing the goal.
2. ** The rationality of the target **
- Whether the goal was too simple or complicated. For older students to do a bridge load test, if they simply stopped at determining which bridge had the greater load without delving into the principles (such as structural mechanics principles, material characteristics, etc.), the goal would be too simple. On the other hand, if a child were to set a goal that was too complicated to calculate the theoretical weight, it would be beyond their ability.
** 2. Experiment preparation **
1. ** Material preparation **
- Whether the materials were sufficient and suitable. For example, in the paper bridge load bearing experiment, the material, size, and thickness of the paper strips were consistent. If they were inconsistent, it might affect the accuracy of the experimental results. In the bridge load test, the accuracy of the sensors and other testing equipment meets the requirements. If the accuracy is not enough, it may lead to data deviation.
- Whether the spare materials that might be used in the experiment were prepared sufficiently. If the materials were damaged or insufficient during the experiment, it would affect the smooth progress of the experiment.
2. [Knowledge preparation]
- For students, whether they had sufficient prerequisite knowledge before conducting experiments. For example, when conducting experiments related to bridge structures, whether the students understood the basic mechanics principles, the types of bridge structures, and other knowledge. If they lacked this knowledge, it might cause the students to only operate mechanically during the experiment process and not be able to understand the scientific principles behind the experiment.
** 3. Experiment process **
1. ** The rationality of the experimental steps **
- Whether the experimental steps were clear, concise, and feasible. When a child is doing a paper bridge load bearing experiment, is it easy for the child to understand and execute the operation of placing an object in the middle of the bridge? If the experimental steps were too complicated or vague, it would cause the students to make mistakes and affect the results of the experiment.
- The logical connection between the experimental steps. When carrying out the bridge load test, whether the steps from the static load test to the dynamic load test conform to the logical order of scientific research, and whether it helps students gradually understand the performance of the bridge.
2. ** Student participation **
- Whether the students actively participated in the experiment. For example, in the classroom teaching related to the novel "Bridge," the students were not very enthusiastic when reading the sentences describing the old secretary, and similar situations might exist in the experiment. If the students 'participation was low, it might be because the experimental content was not interesting enough, the experimental steps were too cumbersome, or there was a lack of effective guidance.
- How to encourage students to actively ask questions and explore. During the experiment, whether the students had enough opportunities to raise their own questions and ideas. If the students only followed the established steps and did not think and explore on their own, it meant that the experiment did not stimulate the students 'innovative thinking.
3. ** Experiment Guide **
- Whether the teacher's guidance was timely and accurate. If the teacher did not correct the wrong operation method of the child (such as the incorrect way to place the heavy object) in time when the child was carrying out the paper bridge bearing experiment, it would affect the experiment results. In the more complicated bridge load test, the teacher would answer the students 'questions about the abnormal data accurately. If it was not accurate, it would cause the students to misunderstand the experimental principle.
- Was the method of guidance appropriate? Should he tell the students the answer directly or guide them to think about it and come to a conclusion? If he always told the answer directly, it would not be conducive to the cultivation of students 'independent thinking ability.
** 4. Experiment results and summary **
1. ** Analysis of the results **
- Whether or not the students were guided to conduct an in-depth analysis of the experimental results. In the paper bridge load bearing experiment, it was not enough to just figure out which bridge had the greater load bearing capacity. Students also needed to be guided to analyze the reasons behind it (such as the force distribution of the paper, the stability of the structure, etc.). In the bridge load test, whether the analysis of the verification coefficient, relative residual strain and other data is in-depth, and whether the students understand the meaning of the bridge performance represented by these data.
- The connection between experimental results and theoretical knowledge. Whether the experimental results were effectively combined with relevant theoretical knowledge (such as structural mechanics, material mechanics, etc.). If students only remembered the experimental results and could not relate them to theoretical knowledge, it meant that experimental teaching was inadequate in this aspect.
2. ** Comprehensiveness of the summary **
- Whether the summary covered all aspects of the experiment, including the achievement of the experimental objectives, the problems in the experimental process, the performance of the students, and the direction of improvement for future experimental teaching. If the summary simply repeated the experimental results without a comprehensive reflection on the entire experimental process, then it would not be effective for subsequent teaching.

These novels covered all kinds of attributes from ancient and modern times, including the plot of childbirth abuse and normal childbirth. However, there was no recommendation for the ending novel of the book, so it was impossible to confirm whether there was a recommendation for the modern novel.
turntable bearingSlewing bearings are large bearings that can simultaneously withstand large combined loads such as an axial-direction load, a radial-direction load, and an overturning moment. It has the characteristics of compact structure, convenient guidance and rotation, simple installation and easy maintenance. Slewing bearings usually had mounting holes, internal or external gears, grease holes, and sealing devices, so they could meet the different needs of various hosts working under different working conditions. Slewing bearings are usually composed of inner rings, outer rings, rolling elements, and isolation blocks. It was widely used in large-scale revolving devices in engineering, mining, smelting, wind power and other industries.
