PC acts as a teacher

) PC acts as a teacher:
Computers that can effectively act as a teacher, and by providing it with some simple programs, and then the learner training on how to use such programs. In light of this, the computer has the task of explaining the lessons in all courses, and the task of training the learners, and testing, and to show results and save, and edit letters for each student entitled to know the outcome. Any computer that acts as a teacher’s role is almost to be integrated in terms of training and the explanation and clarification of errors, and then assess the learner in terms of its level and its ability to scientific achievement.
2) provide immediate feedback.
Based computer to provide instant feedback for each individual learner, and diagnose weaknesses, and audit-related, and clarification and to facilitate the difficult concepts.
It is intended instant feedback in the field of computer not only strengthen the right response, but also address the special learner and correct errors. As the learning happens when you strengthen the right to respond in real time, this happens, the computer learning effective because it goes beyond mere strengthening of the right response, the learner to diagnose and correct the errors.
3) motivate learners to learn.
The computer because it means a sophisticated explanation, but its potential clear and abilities in the presentation of course material, device has the power to attract the learner to learn, and because of the ease of use of this device is the rapid display of information that focus on different types of knowledge that lies behind that information, it is a catalyst for information for learners to do more experiments, and thus to learn more in terms of quantity and quality.
This is in addition to that it can show that the computer is an incentive for learners to receive various types of knowledge through many ways including:
* The computer reward learners who use it, and the reward in this case moral.
* The computer-related course material in terms of content and structure and logical sequence motive because learners learn seriously and interesting.
* The strong desire of the students – through their determination to programs – to work to solve the problems they face in mathematics.
This shows that the computer has the attention of the educated and interested in the degree of proficiency academic article related to it, also try to apply what has been learned in solving a lot of math problems, this is what was observed when teaching computer rapporteur of passion educated more learning and actual practice on the PC, and try some of them design a variety of programs for various types of different problems.
4) assist in the development of thinking.
The computer instrumental in solving many of the problems facing the learner, and that the information that resulted from the computer always rebuild human thinking technology, which in turn can improve the mental development of the learner, learner through computer technology and the associated information to him able to guess and analyze problems Educational more sophisticated manner. Therefore, the computer encourages individual learning which will only be achieved through the allocation of a computer for each learner individually. Or as much as possible to limit the number of learners on all computers (only two on each machine).
To sum up, the computer is an effective way for individual learning, and that if used properly used, in terms of in-depth study him, and exploit all its potential, and the perception of sound bases to be used in accordance with the environment surrounding it.
5) assist in the development of self-learning.
Of computer self-learning ability development through research and investigation about how to solve the various problems that correspond to the learner using programming, it is evident from the rise in the collection of the learner in a lot of educational material that has been the use of a computer in her study, and educational programs designed for users grow their learning property Self-than those who do not use these programs actually used.

Students may connecting the incidents they see in the film

Students may connecting the incidents they see in the film, although it has no correlation between these events.
Per do so, the teacher students to take note of the time the events in the film and their relationship to each other and the time it took the event in nature.
The teacher must also be assessed students take advantage of the educational watch any film even standing by himself on the mistakes of the students.
3. erroneous perception of size:
Of the most common mistakes made by children located at the watching of a movie not to appreciate the true size of something they see on the screen for example, when you watch a film about the Pyramids and the Sphinx children may not realize the true size of the pyramids and the Sphinx and compare it rise building or a moving car in the street. So it must be noted the real sizes and heights of things.
4. wrong conclusions:
It is also common mistakes after watching movies is the perception of the viewer and his conclusion to things that are not true at all. For example, when foreign watched a film about the pyramids area and appears in the film a number of beauty, many of them imagined that Cairo but Egypt as a whole is full of beauty and beauty is almost the main means of transportation in Egypt .
The event that ABC US television station offered in one-day Saturday April 1989 at the end of a news bulletin at six in the evening a paragraph about that camel is the means of transport Unfortunately, the film was to dozens of Beauty cross in front of Cairo University and are going to bridge the university is on its way to the slaughter, but the Introduction bulletin did not mention it and merely that beauty in Egypt way public transport … and so the film gave the impression to some members of the American people, who did not visit Egypt by that beauty really used as a means of public transport in Cairo.
So it was the responsibility of the teacher is very significant in clarifying the film material and hence preventing the wrong conclusions for kids and even adults.

5. film language:
 sometimes be some films in a language other than Arabic and in this case it is difficult for students follow-up film material and carrying a large degree desired to take advantage of the film.
 film may contain many technical terms Technical terms that may be above the level of students’ understanding of which hinders their access.
 film may be accompanied by the suspension or be the basis of dialogue in the film is accented tone that date back as students, making it difficult to understand the contents of the film.
6. economic aspects:
Certainly come between the economic cost of the determining factors for the selection of educational means. As the movie rental or borrowed may not cost much, and the film is considered an educational cheap if you provide the right film.
7. Some technical difficulties:
By film students must chosen because it has no cracks or flaws in the sound which reduces its importance.

The benefits of using animated films in education and teaching

The benefits of using animated films in education and teaching:
1. facilitate the training of motor skills through the use of slow motion photography and benefit from signs of educational institutions such as schools, universities and sports clubs.
2. helps in the formation of concepts or preliminary information to the students about the academic subject, or a particular issue in preparation for a collective discussion of the season.
3. speed up or slow down the natural movement of the visual things, giving it signed more than the imagination of students as in the sciences, such as planets, earthquakes, volcanoes and magnetic fields and nuclear tests movements.
4. effectiveness in children’s education.
5. used in the provision of study modules or summarized and reviewed, there are movies can offer a comprehensive theory about a certain topic in preparation for study in the classroom so that these films have contributed to raise the tendency under study the issue.
6. educational films reflect the reality in form and movement to the point of not prevail against it any other way but to educational use of the same reality.
7. get bigger or smaller size of the real things as it is in bacteria and parasites and solar planets and technological Alehiaiah that occur during the later period of time.
8. reduce the time and costs required by some academic education topics as is the case in a number of physical and chemical science experiments that need for expensive equipment and materials complex and an absolute and a relatively long time for testing and implementation.
9. You may representation and to clarify some of the incidents and processes invisible like electricity, sound and identifies gases and the transition from one state to another.
10. provide through forms or colored images and substantive infiltration useful sensory aesthetic experiences for other means fail to achieve them.
11. reach information for pupils automatic, direct and quick manner, especially with students who are not interested in reading the printed educational materials.
* Steps the use of films in teaching:
The success of the use of educational films in teaching depends primarily on what he is doing based teacher teaching in a plan or a strategy to achieve maximum educational benefit from the screening of the film as it is in the lack of an organized and careful planning turns the educational goal of the film to an entertaining goal, bringing the Showing the film in a waste of time Chapter Hall.
So must the teacher when using films in education to follow these steps:
First selection phase the film:
The teacher should be in this step is that some of the procedures, including:
1. Analysis of the characteristics of the students:
The determination of educated people who are the beneficiaries in the film is the first step by the teacher in the development plan for the use of educational films in the classroom Properties. And it includes cultural and scientific aspects, and concerns and trends, as well as take into account the Sunni-old learners.
2. Identification of the target accurately:
You must specify the educational objectives for the lesson clearly and accurately before choosing educational contents of the film, and make sure the film over the content link to the objectives of the lesson. If the lesson goals in the cognitive domain should focus on the facts and concepts in the film material, but if the lesson objectives are limited to teaching manual skills should be content that the film focuses on teaching these skills.
3. Choose the film:
Even the choice of suitable film material should refer to specialized catalogs and indexes for that which is found public libraries and departments of teaching aids educational areas. This step is easy if they took into account the implementation of the previous two steps carefully.

Types of educational films:

Types of educational films: educational films differ in terms of genre and in terms of the display using the runtime called educational films according “to view the film and that there are 35 mm, 16 mm 0.8 mm, but popular movies use are films 8 mm, Movies 16
A. movies 8 mm: Showing these films 8 mm and often “what be animated movies silent, but appeared in the recent films 8 mm-speaking, so there are two types of films 8 mm two films 8 mm plain films 8 mm super and the two have the same width, but the difference between them in the number of holes on both sides The film, and the existing interval between frames, following figure shows the points of agreement and disagreement between them.
(B) films 16 mm: and the width of these films 16 mm which is the most widely used films “in education, including the animated silent movies and animated films and speed-speaking framework” per second and offers the same speed as can be divided into educational films in terms of supply of them for presentation to:
1-short educational films that take a view for no more than 4 or 5 minutes and address the concept of “one” or a specific skill or mobility is one problem, and may be silent or speaking and movies recorded on 8 mm or 16 mm.
2. educational documentaries: It is that record the events of life situations to highlight some aspects of the kidneys evidenced by the facts and certain concepts or usually recorded production steps in factories, farms and centers of work and duration of presentation of 15-35 minutes to that recorded on film 16 mm.
3. Permanent educational films: They are similar to a large extent non-documentary films that are produced stationing body or institution and movies recorded on 16 mm, 35 mm.
Educational and technical considerations to take into account when a product of educational films:
When thinking of educational film production, the most important stages of the production is the preparation phase that precedes the filming will include defining the idea of ​​the film will include defining the idea for the film from the reality of the subject matter and should therefore some of the considerations taken into account when production:

A. educational considerations:
1 – that focus on the local environment and related flowed and animal and plant materials to be so that they are distinctive features of the local film features.
2 – that the authors of the scientific material for films presented to the lack of accumulation of information and ideas based on “the supply of the educational use of the film is to simplify the information and scientific theories.
3 – n choose vocabulary words and comment on the films so that commensurate with the level of awareness of students and use the vocabulary of the highest level.
4 – to be the drafting of the comment and the image of the film in a way raise student participation in the scientific material presented in terms of pulling his attention provoking him to think about.
5 – it is important to prepare with all the movie “teacher’s guide” addressed to the movie topics that need further explanation or clarification as to the extent appropriate to provide him with information that may be used to comment on the film.
(B) technical considerations:
1. Introduction to the film are some interesting elements and contain appropriate dazzling.
2. can be used with some animation, models, paintings and comic started on condition that expands topic by such means.
3. You must pay attention to the process of “color correction” during the acidification and of course even be colorimetric properties of movie clips and watch commensurate with each other.
4. must be taken into account in the meeting on to be a rhythm appropriate to the movement of the film and the student’s ability to absorb its information and its meaning 2 and not necessarily continue for the duration of the offer, but which leave time slots are silent to allow the student to contemplate the image displayed or absorb the meaning.
5. Ballqtat taken into account when the use of aliases that are appropriate for the context of public offerings in terms of subject matter and in terms of the image and the degree of contrast and clarity.

The successful teacher is the one who can choose the appropriate

Designer means you should try them during the preparation stage and the stage before use. The teacher who try out the means by which it can be used to take a decision on the use of sound.
6. provide the right atmosphere for the use of the means:
It is taking into account the circumstances surrounding the use of natural means such as lighting, ventilation and the provision of devices and the method developed.
7. Lesson lack of congestion means:
The successful teacher is the one who can choose the appropriate method or means to study it, and his disciples, who decide to use one or more means in light of the educational goals set by, and define the role all the way and percentage in achieving these goals.
8. calendar means:
The foundations of which must be taken into account in the preparation of both the means or when used method is to evaluate the process and include two major phases: the internal calendar, and external calendar.

Warning in the use of educational films.

Educational animated films:
Concentrated importance of the educational film in its ability to supply the learner a real experience where characterized the educational film for any of the other teaching aids to the enrichment of the Queen of imagination and perception when the learner as possible under his view rare situations, or those that can not be captured or older to happen for a long time. The film also presents the educational experiences that can be acquired by the learner.
Historical development of the use of educational films:
If we go back to the nineteenth century past, we find that for the manufacture of animations artistic beginnings linked to attempts Edward bloody and Gariz Greene then Edison and this was in the late nineteenth century to the piece, we find that the first use of film education in education was during the First World War when a team of scientists then self using a set of animated films sincere as a means of training and then followed this group films University educational tendency in the material of American history-and continued to be used animated films silent so prevalent twenties then possible installation of audio tracks on the side of the film that is sound facilities for animation and I knew then animation films and audio was the beginning of the use of moving images broadcast in education is the World War II period, and then spread in the field of education, including movies and appeared 16 mm, 35 mm.
What educational animated films:
Animation is a strip of clear plastic acidified and registered by the second set of images that give a sense of movement and a sense of movement to stop imaging and display capabilities, and there are three types of movement:
- Natural movement of something Photographer:
And this is done through imaging at a rate of speed, a natural
24 frames \ seconds, then displays the same thing Illustrator imaging speed appears unusual movement on the screen and occupies the same period of time that it takes in fact.
- Rapid movement:
And movement through imaging at a lower rate than normal capacity, for example, 3
Blew the \ seconds, then displays these images at normal speed that any time which takes 40 Thanihvi imaging exposure in a time period of 5 seconds.
- Slow motion:
And faster than the natural rate is imaging If the normal 24 frames \ second, the slow motion require imaging at a faster rate, for example,
48 framework \ seconds, and then subjected to normal speed any time to display twice the time taken in photography.
And the contents of the film about the concept or the subject of a certain Darcy in one area contains the movie on distributed holes on both sides of the film in case if the silent either if the movie provider sound Vtkon holes on one side of the film and the other side recorded the sound and shows the sound track in the form of a white line or black on the film .oasgel length of the sound on the film in two basic ways:
Magnetic way: and where the face of the film covered with iron oxide midwife of magnetization and organizes this article molecules by vibrations and Tirat recorded sound through the magnetic head and maligned on this method is that the film exhibition to cracking with repeated offer.
Optical way: Registration is on the side of the optical film without the presence of iron oxide which is a recording of electrical vibrations on the film where sound is installed on the film during the filming directly and is one of the more roads
Prevalent, and be in the form of white or black line on both sides of the film. This sound and retrieve scanned by the passage of light of the lamp to the sound of drum sound that works to reverse the PV cell that converts light energy into electrical energy low magnified through the loudspeaker.
