ORGANIZATION OF LESSONS IN PHYSICS WITH ELEMENTS OF A SYSTEM-ACTIVITY APPROACH

USING THE VERNIER DIGITAL LABORATORY IN THE LESSONS AND IN COURSE ACTIVITIES

Physics is called experimental science. Many laws of physics are discovered thanks to observations of natural phenomena or specially designed experiments. Experience either confirms or refutes physical theories. And than earlier man learns to conduct physical experiments, the sooner he can hope to become a skilled experimental physicist.

The teaching of physics, due to the peculiarities of the subject itself, is a favorable environment for the application of a system-activity approach, since the course of physics high school includes sections, the study and understanding of which requires a developed figurative thinking ability to analyze and compare.

Especially effective methods works areelements of modern educational technologies, such as experimental and project activity, problem learning, the use of new information technologies. These technologies make it possible to adapt the educational process to the individual characteristics of students, the content of training of varying complexity, and create prerequisites for the child to participate in the regulation of their own educational activities.

It is possible to increase the level of a student's motivation only by involving him in the process of scientific knowledge in the field of educational physics. One of the important ways to increase student motivation is experimental work.After all, the ability to experiment is the most important skill. This is the pinnacle of physical education.

A physical experiment makes it possible to link practical and theoretical problems course. When listening educational material schoolchildren begin to get tired, and their interest in the story decreases. A physical experiment, especially an independent one, well removes the inhibitory state of the brain in children. During the experiment, students take an active part in the work. This contributes to the development of students' skills to observe, compare, generalize, analyze and draw conclusions.

Student physical experiment is a method of general educational and polytechnical training of schoolchildren. It should be short in time, easy to set up and aimed at mastering and working out specific educational material.

The experiment allows organizing independent activities of students, as well as developing practical skills. In my methodical piggy bank contains 43 frontal experimental tasks only for the seventh grade, not counting the program laboratory work.

During one lesson, the vast majority of students manage to complete and complete only one experimental task. Therefore, I selected small experimental tasks that take no more than 5-10 minutes in time.

Experience shows that conducting frontal laboratory work, solving experimental problems, performing a short-term physical experiment is several times more effective than answering questions or working on textbook exercises.

But, unfortunately, many phenomena cannot be demonstrated in the conditions of a school physics laboratory. For example, these are phenomena of the microworld, or fast processes, or experiments with devices that are not available in the laboratory. As a result, studentsexperience difficulties in studying them, as they are not able to mentally imagine them. In this case, a computer comes to the rescue, which can not only create a model of such phenomena, but also allows

Modern educational process is unthinkable without the search for new, more effective technologies designed to promote the formation of skills for self-development and self-education. These requirements are fully met by the project activity. IN project work the goal of training is the development of independent activity among students, aimed at mastering new experience. It is the involvement of children in the research process that activates their cognitive activity.

A qualitative consideration of phenomena and laws is an important feature of the study of physics. It's no secret that not everyone is able to think mathematically. When a new physical concept is presented to a child first as a result of mathematical transformations, and then a search for its physical meaning takes place, many children have both an elementary misunderstanding and a bizarre “worldview” that in reality there are formulas, and phenomena are needed only to illustrate them.

The study of physics with the help of an experiment makes it possible to learn the world of physical phenomena, observe phenomena, obtain experimental data to analyze the observed, establish a connection this phenomenon with a previously studied phenomenon, introduce physical quantities, measure them.

The new task of the school was the formation of a system for schoolchildren universal action, as well as the experience of experimental, research, organizational independent activity and personal responsibility of students, the acceptance of learning goals as personally significant, i.e. competencies that determine the new content of education.

The purpose of the article is to study the possibility of using the Vernier digital laboratory to develop research skills in schoolchildren.

Research activity includes several stages, ranging from setting the goal and objectives of the study, putting forward a hypothesis, ending with the experiment and its presentation.

Research can be both short-term and long-term. But in any case, its implementation mobilizes a number of skills in students and allows the formation and development of the following universal learning activities:

  • systematization and generalization of experience in the use of ICT in the learning process;
  • assessment (measurement) of the influence of individual factors on the performance result;
  • planning - determining the sequence of intermediate goals, taking into account the final result
  • control in the form of comparing the method of action and its result with a given standard in order to detect deviations and differences from the standard;
  • compliance with safety regulations, the optimal combination of forms and methods of activity.
  • communication skills when working in a group;
  • the ability to present the results of their activities to the audience;
  • development of algorithmic thinking necessary for professional activity V modern society. .

Vernier digital laboratories are equipment for conducting a wide range of research, demonstrations, laboratory work in physics, biology and chemistry, design and research activities students. The laboratory includes:

  • Distance Sensor Vernier Go! Motion
  • Temperature sensor Vernier Go! Temp
  • Adapter Vernier Go! Link
  • Vernier Hand-Grip Heart Rate Monitor
  • Light sensorVernier TI/TI Light Probe
  • A set of educational and methodological materials
  • CosView Interactive USB Microscope.

With Logger Lite 1.6.1 software you can:

  • collect data and display it during the experiment
  • choose various ways data display - in the form of graphs, tables, scoreboards of measuring instruments
  • process and analyze data
  • import/export text format data.
  • view video recordings of pre-recorded experiments.

The laboratory has a number of advantages: it allows obtaining data that is not available in traditional educational experiments, and makes it possible to conveniently process the results. The mobility of the digital laboratory allows you to conduct research outside the classroom. The use of the laboratory makes it possible to implement a system-activity approach in lessons and classes. The experiments carried out with the help of the digital laboratory "Vernier" are visual and effective, which allows for a deeper understanding of the top of the head by students.

By applying a research approach to teaching, it is possible to create conditions for students to acquire the skills of scientific experimentation and analysis. In addition, learning motivation is increased through active participation in the process of a lesson or class. Each student gets the opportunity to conduct their own experiment, get the result, tell others about it.

Thus, we can conclude that the use of the Vernier digital laboratory in the classroom allows students to develop research skills, which increases the effectiveness of learning and contributes to the achievement of modern educational goals.

Digital labs are the next generation of school science labs. They provide the opportunity to:

  • reduce the time spent on preparing and conducting a frontal or demonstration experiment;
  • increase the visibility of the experiment and visualization of its results, expand the list of experiments;
  • carry out measurements in the field;
  • to modernize already familiar experiments.
  • With the help of a digital microscope, each student can be immersed in a mysterious and fascinating world, where they will learn a lot of new and interesting things. The guys, thanks to the microscope, better understand that everything living is so fragile and therefore you need to be very careful with everything that surrounds you. The digital microscope is a bridge between the real ordinary world and the microcosm, which is mysterious, unusual and therefore surprising. And everything amazing strongly attracts attention, affects the mind of the child, develops creativity, love for the subject. A digital microscope allows you to see various objects at magnifications of 10, 60 and 200 times. With it, you can not only examine the object of interest, but also take a digital photo of it. You can also use a microscope to record objects on video and create short films.
  • The set of digital laboratory includes a set of sensors with the help of which I carry out simple visual experiments and experiments (temperature sensor, CO2 content sensor, light sensor, distance sensor, heart rate sensor). Students put forward hypotheses, collect data using sensors, analyze the received data to determine the correctness of the hypothesis. The use of a computer and sensors when conducting scientific experiments in the classroom ensures the accuracy of measurements and allows you to continuously monitor the process, as well as save, display, analyze and reproduce data and build graphics based on them. The use of Vernier sensors contributes to safety when conducting classes natural sciences. Temperature sensors connected to computers prevent students from using mercury or other glass thermometers that can break. I use the equipment both in the lessons of physics, chemistry, biology, computer science, and extracurricular activities when working on projects. Students master the methods of the following activities: cognitive, practical, organizational, evaluation and self-control activities. When using digital laboratories, the following positive effects are observed: increasing the intellectual potential of schoolchildren; the percentage of students participating in various subject, creative competitions, design and research activities and increase their effectiveness.
  • Application electronic educational resources should provide a significantinfluence on the change in the activities of the teacher, his professional and personal development, initiate dissemination of non-traditional models of lessons and forms of interaction between teachers and studentsbased on cooperation, andemergence of new learning models, which are based onactive independent activity of students.
  • This is in line with the main ideas of GEF LLC, methodological basis which issystem-activity approach, according to which "the development of the student's personality on the basis ofassimilation of universal educational activitiescognition and development of the world is the goal and main result of education.
  • The use of electronic educational resources in the learning process provides great opportunities and prospects for independent creative and research activities of students.
  • Concerning research work– EER allow not only to independently study the descriptions of objects, processes, phenomena, but also to work with them in an interactive mode, solve problem situations and connect the acquired knowledge with phenomena from life.

Other articles are devoted to questions that lie within physics. What is mass, what is Ohm's law, how does an accelerator work - these are internal questions of physics. But as soon as we ask a question about physics in general or about the interaction of physics with the rest of the world, we have to go beyond it. To look at her from the outside, to see her precisely "as a whole." And now we will do it.

How physics is arranged and works

Imagine that your goal is to build bridges. What do we have to do? Mining iron ore, smelting steel, making nails, felling timber, sawing logs, driving piles, laying decking, and so on. Learn to make bridge calculations, and learn by yourself and teach others - and count, and build. It is not bad to exchange experience with other bridge builders, you can start publishing the magazine "Across the River" or the newspaper "Our Svay". What's important is that it's a process, and at every step we can tell you exactly what to do; you can feel a nail, you can sit on a hammered pile and fish. The results of the bridge calculation can be compared and verified, a model of the bridge can be built and tested. In addition, in the course of all this activity, a skill, ability, construction technology and a special language for describing bridges arise. Builders use their own terms, understandable only to them - console, caisson, diagram, etc.

This is how physics works. Those who do it create accelerators, microscopes, telescopes and many other devices, write and solve equations that describe the relationship between various parameters of our world (for example, the relationship between pressure, temperature and wind speed in the atmosphere). Like bridge builders, physicists create their own language and system for teaching future physicists. The experience of solving problems is accumulating, the technology of cognition is emerging.

All this does not fall from the tree by itself, like a mythical apple. Instruments are expensive and do not always work well, not everything can be understood, not all equations can be solved, and it is often unclear how to write them down, not all students study well, etc. But in the end, the understanding of the world improves - i.e. Today we know more than yesterday. And since we know from books that the day before yesterday we knew even less, we conclude that tomorrow we will know even more.

This is physics - the known world, the process of knowing the world, the process of creating the technology of knowing, the description of the world in a special "physical language". This language partially overlaps with the regular language. The words "weight", "speed", "volume", etc. exists both in physical language and in ordinary language. Many words exist only in physical language (exciton, gravitational wave, tensor, etc.). The words of ordinary language and the words of physical language can be distinguished: you can explain to any person - so that he says "understood" - what is weight and speed, but you will not be able to explain to almost anyone what a "tensor" is. By the way, professional languages ​​intersect: for example, the word "tensor" is also found in the language of bridge builders.

How physics is related to society

Physics, as well as the construction of bridges, is connected with the outside world. The first connection is that being a physicist (as well as a builder) is pleasant. Man survived because he learned new things and did new things. Mammoths had warmer wool, saber-toothed tigers jumped better, but the two-legged one reached the final. Therefore, as an adaptive feature, as support for the correct way of action that improves survival, the joy of recognition and the joy of creativity are laid in a person. Just like the joy of love or friendship.

The second connection between physics and society is that being a physicist (as well as a builder of bridges) is prestigious. Society respects those who do good for it. Respect is manifested in salary, in ranks and orders, admiration of girlfriends and friends. The degree of this respect and its forms at different stages of the development of society can, of course, be different. And they depend on the general condition of a given society - in a country that wages many wars, the military is respected, in a country that develops science - scientists, in a country that builds - builders.

Everything that is written above applies not only to physics, but also to science in general - despite the fact that although biology and chemistry have many of their own characteristics, they themselves scientific method they have the same as in physics.

Where does pseudoscience come from?

A person seeks pleasure and does not seek - if this in itself does not give him pleasure - to work. Therefore, it is quite natural that next to physics, in which one has to work hard to get pleasure from the knowledge of truth and recognition by society, there is some other area of ​​\u200b\u200bactivity, called, to put it politely, "parascience" or "pseudoscience".

Sometimes they say "pseudoscience", but this expression is inaccurate - it is customary to call a conscious and purposeful deception a lie, and among the figures of pseudoscience there are quite a lot of sincerely mistaken people. We will mainly talk about pseudophysics, although in Lately very popular, for example, pseudohistory and pseudomedicine. In accordance with the properties of physics listed above, pseudophysics can be of several types.

Type 1- designed primarily to receive money and honor from the state. The traditional theme is "superweapon". For example, shooting down enemy missiles with "plasma clots". Similar ideas were successfully used to pump money out of the budget in Soviet times, and they were used on the other side of the ocean. For example, the use of telepathy to communicate with submarines. True, the system of independent expertise and less corruption prevent the development of this type of pseudoscience in other countries.

Type 2- designed mainly to satisfy their own ambitions. Traditional topics - the solution of the most complex, fundamental and global problems. Proof of Fermat's theorem, trisection of an angle and squaring of a circle, perpetuum mobile and an internal combustion engine on water, elucidation of the nature of gravity, construction of a "theory of everything", etc. Unlike Type 1 papers, some of these papers cost next to nothing, except for publication money.

In general, pseudoscience is based on two psychological characteristics people - the desire to get something (money, honor), without making an effort or to learn something, also without making an effort ("the theory of everything"). People are especially willing to believe in all sorts of miracles (UFOs, instant heals, miracle weapons) during a period of failure - either personal or public. When the complexity of the tasks facing a person or society turns out to be higher than usual and many people feel bad. A person in such a situation turns either to religion (as a rule, to its external paraphernalia), or to pseudoscience, or to mysticism. For example, today, in terms of the degree of interest in mysticism, Russia occupies one of the first places in the world, far ahead of Western societies living a normal life.

Is there any harm from pseudoscience

There is no particular harm, however, directly from the belief in UFOs and plants that feel at a distance that they are about to be plucked. Worse than the other - a person who has learned to perceive everything uncritically, who has unlearned to think with his own head, becomes an easy prey for all sorts of crooks. And those who promise to make untold money out of thin air, and those who promise to build a paradise tomorrow and solve all problems, and those who undertake to teach him everything in thirty hours - at least foreign language, even karate, even management.

Pseudo-science brings direct harm, perhaps, only in one case - when it is pseudo-medicine. Those who were treated by healers, sorcerers and hereditary fortune-tellers usually can no longer be saved by doctors. It is sometimes said that healers and sorcerers heal by suggestion, hypnosis, etc. It is possible, but, firstly, it has not been proven, and, secondly, a short-term improvement is usually achieved by suggestion, and the disease goes on as usual and leads to a natural outcome.

How to distinguish between science and pseudoscience?

Or, at least, physics and pseudophysics? Let us recall the main features of physics (and science in general) listed above.

First. Physics creates knowledge about the world that increases with time. And not in the form of separate revelations, but in the form of a system of related statements, and the reliability of each is a consequence and cause of the reliability of others. Any physical work develops some results of previously performed work (either using or challenging). Previous results in the same area cannot be ignored.

Second. Physics allows you to do "things" (for example, build bridges - through the study of the properties of materials and the development of new ones). Therefore, we check the reliability of modern physics every day a hundred times - without it there would be no radio and television, without it the car and subway would not run, without it neither a cell phone nor an iron would work.

Physics accumulates skill, technology, apparatus of cognition, builds its own language in which this experience is realized, and an education system - both for those who will work in physics and for those who will not.

Pseudoscience, which satisfies the ambitions of its creators and people's desire for a simple "explanation" of everything in the world, differs from science in all these points. She doesn't do anything on that list.

And in one aspect it imitates science. What is "science" for a person? First of all, it's a lot incomprehensible words, some of which (holography, proton, electron, magnetic field, vacuum) are often repeated in newspapers. In addition, science means ranks: academician, corresponding member, vice president, and so on. Therefore, pseudoscience uses a lot of " scientific words”, and completely out of place, and usually walks hung from neck to knees with titles. Today, every ten honest lunatics and five normal crooks, having gathered together, declare themselves an academy.

Why physicists don't like this topic

People who want to understand the issue and understand whether there are "solar-terrestrial connections" or is it just incorrect data processing turn to physicists with questions, and physicists usually evade answers. On which the press flourishes, publishing millions of copies of photographs of the “soul leaving the body” (in the picture, the soul looks a bit like a ghost - a cartoon Casper, only translucent). Let's try to understand the psychology of physicists who, in violation of the traditions of their science, evade a clear answer and, lowering their eyes, mutter something like "maybe there is something there."

The first and main reason for this behavior is that it is much more interesting for a physicist to study nature than to deal with madmen, crooks and people fooled by them.

The second reason is that if a person is hopelessly ill, then (in Russian culture, but not in Western culture) it is customary to tell him a lie and, thereby, console him. If people feel bad and they turn to faith in a lapel, a love spell and the strongest sorcerers in the third generation, then it’s somehow not good to take it away from them.

Third reason. Unwillingness to go into conflict because of "nonsense". Will you tell him that mice do not emit gravitational signals at the moment of death, or that there are no holes in the aura simply because there is no aura, and he will begin to accuse you of pursuing and suppressing the sprouts of new knowledge?

Fourth reason. Unwillingness to pass for a retrograde, censor, Cerberus, despot, etc. Physicists remember Soviet times when not a single word could be published without permission - and therefore do not want to even remotely look like censors.

The fifth reason is a bad conscience. The cutting edge of science goes deep into nature like a mining machine. The length of the tunnels is growing, society is breaking away from science, and shamans are filling the gap. And this happens not only in Russia, but also in other countries. Maybe scientists should be more involved in the popularization of science and educational activities? Then there would be less shamanism.

The sixth and final reason - what if there really is something there? Let's consider this situation in more detail.

And suddenly there really is something

Of course, when the stories about levitating frogs begin, everything becomes clear. But in physics it often happens that the data of new measurements "do not fit" into the old theory. The question is what kind of theory and how far they do not climb. If they do not get into the theory of relativity, which has been repeatedly confirmed experimentally (suffice it to say that without it there would be no television and radar), then there is nothing to talk about. If we are talking about unusual magnetic properties or about an anomalously low resistance of a sample made of copper and lanthanum oxides, then this is strange and it would be necessary to sort it out carefully and measure it seven times. And those who figured it out (rather than passed by) discovered high-temperature superconductivity. And information about a substance twice as hard as diamond should be rechecked not 7, but 77 times, since this, as it seems to us, contradicts other, reliably established things.

Agree that the information that a neighbor or a roommate has fallen in love with you will surprise you less than the information that Chuck Norris or Sharon Stone has fallen in love with you. You will check such information much more carefully. As already mentioned, physics is not a list of revelations, but a system of knowledge in which each statement is connected with others and with practice.

The second important property is the controllability of the effect. If a cat meowed in the yard, and my voltmeter went off scale, then this is an accident. When this was repeated seven times, then this is a reason to think. But here I go down into the yard, make her meow and record the time of meows, another person, who does not know that I am doing this, records the readings of the device, and the third, who does not communicate with the two of us, analyzes the records, sees matches and says - Yes, we've made a discovery! If this and that coincided seven times with an accuracy of 0.1 seconds, and not a single meow without a twitch of the arrow and not a single twitch without a meow, this will be a discovery. Note that the controllability of the effect makes it possible to increase the reliability of observations and the accuracy of measurements. For example, there may not be coincidences in all cases, and all this will have to be studied for a long time and carefully.

Thus, we see that physics - like all science, by the way - is work; lots and lots of work. The pleasure of knowing how the world works is not given for free. And especially not given in vain is the amazing feeling experienced by a researcher who has just learned something new about the world - something that no one knows yet. Except him.

If you think physics is a boring and unnecessary subject, then you are deeply mistaken. Our entertaining physics will tell you why a bird sitting on a power line wire does not die from electric shock, and a person who has fallen into quicksand cannot drown in them. You will find out whether there really are no two identical snowflakes and whether Einstein was a loser at school.

10 fun facts from the world of physics

Now we will answer the questions that concern many people.

Why does a train driver back up before moving off?

The reason for this is the static friction force, under the influence of which the train cars are standing still. If the locomotive simply moves forward, it may not move the train. Therefore, he slightly pushes them back, reducing the static friction force to zero, and then gives them acceleration, but in the other direction.

Are there identical snowflakes?

Most sources claim that in nature there are no identical snowflakes, since several factors influence their formation at once: humidity and air temperature, as well as the snow flight path. However, entertaining physics says: you can create two snowflakes of the same configuration.

This was experimentally confirmed by the researcher Karl Liebbrecht. Having created absolutely identical conditions in the laboratory, he obtained two superficially identical snow crystals. True, it should be noted: crystal cell they were still different.

Where is the largest reservoir of water in the solar system?

Never guess! The largest storage water resources our system is the Sun. The water is in the form of steam. Its highest concentration is noted in places that we call "spots on the Sun." Scientists even calculated that in these regions the temperature is one and a half thousand degrees lower than in the rest of our hot star.

What invention of Pythagoras was created to combat alcoholism?

According to legend, Pythagoras, in order to limit the use of wine, made a mug that could be filled with intoxicating drink only up to specific label. It was worth exceeding the norm even by a drop, and the entire contents of the mug flowed out. This invention is based on the law of communicating vessels. The curved channel in the center of the mug does not allow it to be filled to the brim, “relieving” the container of all contents in the case when the liquid level is above the channel bend.

Is it possible to turn water from a conductor into an insulator?

Entertaining physics says: you can. Current conductors are not the water molecules themselves, but the salts contained in it, or rather their ions. If they are removed, the liquid will lose its ability to conduct electricity and become an insulator. In other words, distilled water is a dielectric.

How to survive in a falling elevator?

Many people think: you need to jump at the moment the cabin hits the ground. However, this opinion is incorrect, since it is impossible to predict when a landing will occur. Therefore, entertaining physics gives another advice: lie on your back on the floor of the elevator, trying to maximize the area of ​​\u200b\u200bcontact with it. In this case, the impact force will not be directed to one part of the body, but will be evenly distributed over the entire surface - this will significantly increase your chances of survival.

Why does a bird sitting on a high voltage wire not die from electric shock?

The bodies of birds do not conduct electricity well. By touching the wire with its paws, the bird creates a parallel connection, but since it is not the best conductor, the charged particles do not move through it, but along the cable cores. But as soon as the bird comes into contact with a grounded object, it will die.

The mountains are closer to the source of heat than the plains, but on their peaks it is much colder. Why?

This phenomenon has a very simple explanation. The transparent atmosphere passes unhindered Sun rays without absorbing their energy. But the soil perfectly absorbs heat. It is from it that the air then warms up. Moreover, the higher its density, the better it retains the thermal energy received from the earth. But high in the mountains, the atmosphere becomes rarefied, and therefore less heat “lingers” in it.

Can quicksand suck?

In films, there are often scenes where people "drown" in quicksand. IN real life- says entertaining physics - this is impossible. You won’t be able to get out of the sandy swamp on your own, because in order to pull out only one leg, you will have to make as much effort as it takes to lift a car medium weight. But you also cannot drown, because you are dealing with a non-Newtonian fluid.

Rescuers advise in such cases not to make sudden movements, lie with your back down, spread your arms to the sides and wait for help.

Amazing cases from the life of famous physicists

Outstanding scientists, for the most part, are fanatics of their field, capable of anything for the sake of science. So, for example, Isaac Newton, trying to explain the mechanism of perception of light by the human eye, was not afraid to experiment on himself. He injected into the eye a thin, cut out Ivory probe while simultaneously pressing on the back of the eyeball. As a result, the scientist saw rainbow circles in front of him and proved in this way: the world we see is nothing but the result of light pressure on the retina.

Russian physicist Vasily Petrov, who lived in early XIX century and engaged in the study of electricity, cut off on his fingers upper layer skin to increase their sensitivity. At that time, there were no ammeters and voltmeters that could measure the strength and power of the current, and the scientist had to do it by touch.

The reporter asked A. Einstein if he writes down his great thoughts, and if he does, then where - in a notebook, notebook or special file. Einstein looked at the reporter's bulky notepad and said, "My dear! Real thoughts come so rarely to the head that it is not difficult to remember them.

But the Frenchman Jean-Antoine Nollet preferred to experiment on others. Conducting an experiment in the middle of the 18th century to calculate the speed of transmission of electric current, he connected 200 monks with metal wires and passed voltage through them. All participants in the experiment twitched almost simultaneously, and Nolle concluded: the current runs through the wires, well, oh, very quickly.

Almost every student knows the story that the great Einstein was a loser in his childhood. However, in fact, Albert studied very well, and his knowledge of mathematics was much deeper than the school curriculum required.

When the young talent tried to enter the Higher Polytechnic School, he scored highest mark in core subjects - mathematics and physics, but in other disciplines he had a slight shortage. On this basis, he was denied admission. The following year, Albert showed excellent results in all subjects, and at the age of 17 he became a student.
