Nowadays, thanks to the educative technology, we can use diverse alternatives for your favor surroundings of suitable education-learning. There is much variety of resources that can be used with didactic aims, like can be the videos, the new opto-electronic technologies, like the CDs or DVDs, that it is very popular, if not it accessibility that must to use them.
A good method that is used for the learning and that is used is the audio-visual language. Using videos in the educative scope we can get to secure innovating to didactic strategies in the production, publication and socialization of videos made in teaching.
With the videos we can secure a high degree of motivation, by its expressives possibilities, which causes that it is a valuable tool of learning for the student. Thus different possibilities from didactic strategies offer.
We could define an educative video like audio-visual material that can have a certain degree of utility in the education-learning process. All the audio-visual material can didactically be used, whenever its use is based on achieving the objectives that have been proposed by the educational one.
The educative videos can be classified in several types:
* Documentary video. in which form sample ordinate a information on a concrete subject.
* Narrative video. in that they appear the main information for the students.
* Monoconceptual lesson: it is of short duration and it presents/displays a certain concept.
* Thematic lesson: it presents/displays with a suitable and gradual depth the different sections from a concrete subject.
* Motivating video: it is the most important, since it tries to hit, to motivate, to interest.
The functions of the didactic videos can be summarized in.
* Informative: to organize the reality.
* Instructive: to orient, to condition the learning, etc.
* Motivating: to attract, to interest.
* Evaluator: autoobservation, the analysis, etc.
* Investigator: to investigate, an example can be through recordings, etc,
* Metalinguistic: recording, edition, etc.
* Other functions could be: payful, testimonial, innovating, etc.
The video, like audio-visual means, has characteristics distinguish that it of the rest like the following ones:
* To give to permanence to the messages and this allows to its interchange and conservation.
* Instantaneous reproduction of the engraving.
* Re-usasable support.
* It admits the transfer of productions realised by other procedures.
* It presents/displays low definition of image.
* It generates microcomunication processes original.
The video as a didactic resource presents/displays among others characteristic, that has low cost and easy handling, as half of observation (the camera is limited to half register the situations that are being developed), half of expression (it the students can realise so much as the professors), half of self-training (with the video it can reach a high degree of expressiveness), and of training aid (learning in the phase of transmission of the information).
Within this las one we can find several sections, ex: the video-support or educational complemet (by means of images, that can be animated, sonorous) and video as transmission of knowledge (these at some moments can replace the professor in some contents of conceptual or descriptive type and serve as review). The use of educative videos can provide diverse advantages like: the versatily, the motivation, culture of the image, better access to the meaning, more information, repetition without effort, development of the imagination, the intuition. In order to finalize, also they can present/display diverse disadvantages, althoug these do not surpass to the advantes that offer. Two could be the disadvantages, that the videos exactly do not represent the reality or the possibility of instructing since they imply to the subjects.
