Work summary/plan
Service work. In 2009, the company had a large number of production tasks, and it also required high intensity of laboratory work. With the joint efforts of all the staff in the laboratory, all the experimental tasks have been successfully completed. Up to now, more than 300 batches of sand and gravel aggregate, cement, admixture and fly ash have been inspected, 3,245 groups of concrete compressive strength specimens have been inspected, the qualified rate of concrete compressive strength inspection is 100%, 387 groups of various types of concrete have been trial-produced, and more than 3,000 inspection reports have been issued. _ Completed the optimization of concrete mix proportion, reduced cement consumption, saved costs and increased benefits. According to the customer's demand, we have successfully prepared a variety of special concrete products, such as equal strength mortar, high strength fine stone concrete and so on, which make up for many shortcomings in the same industry. This year, the monthly summary statistics of compressive strength of laboratory cement and concrete were carefully made, and the quality control level was judged according to its standard deviation, and the reasons for unsatisfactory data were analyzed and improved.
As the laboratory work of the company itself is a high-tech work, as a technical department serving production and products, it must adapt to the market choice with high-quality products. In the future work, we should strive to improve our professional level and ideological style, and better serve the development of the company with higher work enthusiasm and upward team spirit.
The second part of the experiment summary
School laboratory is an important place to complete teaching tasks, cultivate students' preliminary scientific experiment ability and carry out scientific and technological activities according to the requirements of experimental teaching syllabus, which plays a very important role in carrying out experimental teaching and improving teaching quality. For a school with all kinds of laboratories and complete experimental instruments, management is the key, because only when management keeps up can all kinds of instruments and equipment be used more reasonably and effectively. In this regard, as middle school laboratory staff, we have done the following work in the long-term work practice:
First, strive to improve their own quality.
Experimenters are the basic team of scientific management laboratory, which plays a decisive role in the management and operation of the whole laboratory. A good experimenter can change the face of the whole laboratory and promote the development of experimental teaching; And a poor experimenter will make the whole laboratory dirty, chaotic and poor, thus making the experimental teaching unable to proceed normally. Therefore, each of us experimenters, on the one hand, strengthen political study in peacetime, improve their own quality, and let everyone realize the importance of this work in ordinary work, so as to love their work more. On the other hand, I will continue to study and exchange with my brother schools and units, and participate in the exhibition of experimental equipment and achievements. This not only broadens our horizons, understands the new situation of the development of experimental instruments, but also sees the advanced management experience of brother units, which is conducive to our reference and improvement in future work. At the same time, the school also encourages us to sum up our own experience, write papers, or take part in part-time study to improve our self-cultivation in all aspects. Because of strict requirements and professional assessment, every existing physics, chemistry and biology experimenter can do his job well, keep the laboratory clean and orderly, and prepare experiments quickly and correctly, thus ensuring the smooth completion of various teaching experiments.
Second, improve various rules and regulations.
As the saying goes, without rules, there would be no Fiona Fang. According to the regulations of the higher authorities, combined with the specific situation of our school, our school has formulated relatively perfect rules and regulations, such as laboratory management norms, student experiment norms, laboratory staff responsibilities, laboratory safety protection system, etc., so that all work can be followed and documented. In addition, we also implemented the "application and registration procedures" for the use of dangerous goods, thus ensuring the safety management of dangerous goods. With the joint efforts of experimenters, the smooth implementation of various systems and the normal development of laboratory work are ensured.
Third, scientific management of instruments and equipment.
The standardized management of instruments and equipment is the guarantee for the rational use of instruments, so we have done the following work:
First of all, according to the requirements of establishing accounts, set up general ledger, classified subsidiary ledger and low-value consumables account, and set up counter plates to indicate the number, name and instrument quantity. Usually, the purchased or configured instruments, equipment and articles are registered in a unified number sequence, and the consumed articles are recorded in each classification record book in time. At the end of each semester, the accounts, materials and cards will be verified, and the scrapped instruments will be sent to the "loss report" for verification after approval by the leaders. Finally, transfer the verified quantity to the general ledger and subsidiary ledger, so that towels, materials and cards can be unified.
Secondly, the storage of instruments and articles should be systematic and organized. We keep them according to the Catalogue of Scientific Teaching Instruments and Equipment in Middle Schools newly compiled by the State Education Commission. For example, physical instruments are divided into measuring instruments, mechanics, heat, optics, acoustics and so on; Chemical instruments are divided into instruments, glassware and medicines; Biological instruments are divided into instruments, models and specimens. Then classify and assemble cabinets, and store them in separate cabinets according to the principle of putting light on top and heavy on bottom and hanging straight. Especially for flammable and explosive substances in chemical instruments, we store them in stone kilns.
Third, reasonably maintain all kinds of instruments and strive to extend their service life. The maintenance of instruments is an indispensable part of laboratory management, and prevention should be given priority to reduce natural wear and tear to prolong the service life of instruments. The specific practice of our school is: always check all the instruments to be used before the experiment, and don't let the instruments go to work with' illness'; During the experiment, the problematic instruments are found in time and replaced or properly handled to ensure the smooth progress of the experiment; After the experiment, all the instruments were slightly maintained. At the same time, different methods are used to maintain different types of instruments: for example, after each semester, the microscope is cleaned and wiped, and then put into a dryer for maintenance; Power on electrical appliances regularly to ensure smooth lines; Pay attention to the rust prevention of metal instruments and tools, especially the rotating or sliding parts, and wipe and oil them in time after each use; Do a good job of dust and mildew prevention for optical instruments, especially in rainy season. We also often open the doors and windows of the instrument room for ventilation, and often clean up the dust to ensure that the instrument room is dry, clean and hygienic. Because we usually strengthen the maintenance and repair of the instrument, the instrument is always in a standby state, thus ensuring the normal operation of various teaching experiments.
Fourth, the effective use of instruments and equipment
The purpose of managing the laboratory is to make good use of various experimental instruments. In order to make teaching instruments play a greater role in teaching, first of all, at the beginning of the semester, according to the requirements of textbooks or syllabus of various disciplines and grades, the experimental teaching plan of demonstration experiments and student experiments in this semester is drawn up, including specific dates and various supplies and requirements. Then, according to the teacher's "notice of experiment", the laboratory makes preparations for demonstration experiments and students' grouping experiments in time, and assists teachers to preview demonstration experiments or tutor students to carry out experiments. Students' experiments require "four decisions", that is, setting the stage, positioning, personnel and instruments, to enhance their sense of responsibility.
In order to improve the status of experiments in teaching, we sometimes change some demonstration experiments into student experiments. Teachers teach while doing, and students learn while doing, such as length measurement, force measurement and other experiments, all in accordance with the above methods. This not only increases the opportunities for students to use their hands and brains, but also enables students to master what they have learned more firmly. And some simple experimental materials, such as toothpaste, rubber bands, springs, balloons, cans, coke bottles and so on. We encourage students to find out for themselves and to design experiments with different materials and methods that can reach the same conclusion. Give students more hands-on opportunities, make students have a clearer impression on the establishment of concepts, cultivate students' experimental skills and improve their interest in learning.
Over the years, our school has gained some experience and achievements in the management and use of experimental instruments. Last year, it successfully passed the acceptance of "Qualified Laboratory" in Suzhou Middle School Laboratory, and was awarded the honorary title of "Advanced Collective" this year. However, we are not satisfied with the status quo, because we see that there are still many problems, especially in the new situation, how to gradually realize the modernization of experimental means needs us to explore and summarize constantly, so as to further improve the management level of the laboratory.
The third part of the experiment summary
In the past 20__ years, under the correct leadership and specific guidance of the company, our laboratory, as a functional department responsible for the company's technology development and quality control, all our testers adhered to the team spirit of self, were responsible for the company's product quality, and considered the company's interests, and diligently completed all the quality control and inspection tasks assigned by the company. The laboratory attaches great importance to all the work ideologically, with clear post of the person in charge, high work enthusiasm, good cooperation with other relevant departments, and successful completion of all the test and detection tasks. The following is a summary of the work of the laboratory in 2009:
I. Technical exchange and on-the-job training:
1, all special or important projects, we consciously strengthen technical guidance, inspection, supervision and service to the construction site, ensure product quality, strive to satisfy customers, be responsible for customers, and leave no quality hidden danger for every poured concrete project, so as to reassure customers.

Do the experiment and summarize the fifth chapter
First, biological experiment teaching
Strict experimental preparation system, teachers in each class should hand in the experimental notice to the laboratory according to the experimental plan, one day before the demonstration experiment and two days before the grouping experiment. I will fully prepare the instruments and medicines according to the notice, so as to be accurate, clean, neat and timely, and ensure the success of the experiment once. For some experiments, the experimental teacher also experimented in person in advance. If there are improved experiments or self-made teaching AIDS for teaching, they will explain the usage and precautions to the teachers in time to ensure foolproof. In the experiment, the damaged instruments were punished in strict accordance with the compensation system for teaching instruments. After the experiment, let the teaching teacher fill in the experimental record sheet in time and truthfully. Complete teaching work with good quality and quantity, actively cooperate with biology interest groups to carry out activities, actively participate in teachers' research-based teaching, and strive to improve students' initiative and participation. This semester, I also cooperated with the Academic Affairs Office to successfully complete the experimental examination of the second day of junior high school.
Second, the laboratory management
Formulate an effective method of collecting and returning drugs and instruments in biological laboratories, and always implement it well. It plays a decisive role in drug quality assurance and instrument maintenance, and avoids unnecessary drug waste and instrument damage. Strengthen the daily maintenance of drugs and instruments, extend their service life, and make a contribution to saving costs for schools. For example, microscopes, dissectors and other teaching precision instruments are regularly overhauled, dusted, derusted and maintained. Specimens are properly managed through regular inspection and moth prevention. Flammable, explosive and highly toxic chemicals should be stored separately, locked by two people, strictly controlled and registered to ensure the safe use of such drugs.
Make sure the shopping is registered, the accounts are clear, and the account card corresponds to the work. The borrowing of teaching instruments should be registered in strict accordance with the "Teaching Instrument Borrowing System", returned and recovered on schedule. Fully understand the performance, purpose and operation method of the new experimental instrument, and be proficient in using it. And actively participate in the guidance of students' experimental operation, further exercise the students' practical ability, and better cooperate with the teaching work of experimental teachers.
Damage to glassware and slide specimens should be compensated, and damage to biological instruments and equipment should be scrapped in time and registered. At the end of the first school year, the loss and scrap record form should be submitted to the General Affairs Office in time, and at the same time, the missing biological instruments and required chemicals should be applied for to ensure the normal development of teaching in the next school year. Do a good job in laboratory water and electricity management, fire prevention and gas protection, eliminate potential safety hazards in time, improve students' safety awareness and implement laboratory safety work. Clean the biology laboratory regularly, and do a good job of cleaning the laboratory at ordinary times, so as to integrate it with the beautiful environment of the school.
Third, complete the experiment seriously and pay attention to the operation guidance.
In experimental teaching, whether the experimenter prepares the experiment, the teacher demonstrates the experiment or instructs the students to experiment, the strict attitude towards the experiment should be reflected everywhere by the teacher's words and deeds. Only when the teacher teaches solidly can the students learn solidly. Therefore, it is an indispensable basic link to prepare, teach and guide the experimental class well.
1. previewing the experimental class is the first condition for a good experimental class.
Experiments required in textbooks, whether simple or complex, should be well prepared, and practical teaching plans must be written, and they should be done by themselves before the experiment class, that is, preparing for the experiment. Only by doing this can teachers guide students how to deal with every possible problem in the operation process, see the experimental phenomenon, learn the real experimental methods and scientific knowledge, and cultivate students' ability to find and solve problems. Not preparing lessons, doing experiments in person, imagining things out of thin air, and doing experiments on the blackboard will not have obvious effects, let alone persuasion. There may even be phenomena that should not happen, such as all students failing in the experiment.
2. Pay attention to experimental guidance.
Know that when students experiment, they should not only face the mask, but also guide everything in detail, and at the same time, they should pay attention to avoid arranging instead. From the selection of experimental materials, the assembly of instruments to the operation steps and skills, it is necessary to be scientific and standardized, and to be closely combined with concrete practice. While respecting students' dominant position, teachers should give full play to their guiding role to ensure that the phenomenon is clear and the results are correct. For example, in the experiment of "extraction and separation of chlorophyll", different materials can be used in different seasons.
3. Pay attention to the analysis and summary of experimental results.
Students are required to fill in the experimental report truthfully. When the experiment fails, we should truthfully analyze the reasons for the failure with the students and make up for it after class. If students fail in the experiment, we will help them master the operation skills and succeed through demonstrations, or help them analyze the reasons for the failure and let them do it again until they succeed. We can't let it go, otherwise, the purpose of the experimental class will not be achieved.
Fourth, the existing shortcomings and the direction of efforts
In guiding students' operation, the measures taken are not scientific enough, and students' hands-on operation ability is not very ideal. At the same time, due to the lack of class hours, poor experimental equipment and insufficient time for grouping experiments, the experimental effect has been affected. In the future work, we should strive to improve teaching methods and experimental teaching equipment to meet the needs of students' experiments.
