It is called text to speech, whether oral or written, that has internal coherence. Instructive , on the other hand, is what allows to instruct (teach something).

The notion of instructional text , therefore, refers to speech whose purpose is to leave a teaching to the receiver. Whoever accesses an instructional text, in this way, learns to perform certain actions.
Instructional texts are usually associated with manuals . These documents they provide information to understand the operation of different devices or elements. If a person wants to learn how to use air conditioning equipment, to cite a possibility, they should read their manual: in this instructional text you will find the necessary data to know how to turn on the equipment, how it is programmed, etc.
The instructional text is didactic and it is based on the clarity of his presentation. The objective is that the reader understands the explanations and can apply the knowledge read without help or without the assistance of others people . When the instructional text fails to transmit its teachings to the recipients, it loses its value.
Other interesting information about the instructional texts are the following:
-Its structure must be composed of two parts fundamentally: a first one where the objective is established and a second one where the instructions are collected. In the latter there will be, in turn, three differentiated and fundamental elements: the paragraphs, the sections and the typographic elements.
-They usually have a simple syntax, with ordered and rather short sentences.
-The use is used, above all, of what are conative verbal forms.
Another typical example of instructional text is the gastronomic recipes They are collected in books, magazines, websites and television programs. These recipes They mention, step by step, what an individual should do to prepare certain dishes. The text, in short, instructs the subject. For example: “First we must cut the meat into strips. Then sauté it with a little oil, onion and garlic. Once this is done, we reserve the preparation. In another pot, we boiled the rice noodles in plenty of water for fifteen minutes. Finally, strain the noodles, put them back in the pot, add the meat with the onion and garlic and add a jet of oil. We mix two minutes and we can serve ”.
In the same way, we cannot ignore that in our daily life there are also other texts that can also be considered instructive. We are referring specifically to the following:
-Rules of the game. In the boxes of the board games themselves, either inside or outside, it is where the document that explains their operation is usually included. In this way, when a group is going to have fun with one of those for the first time, they should proceed to read the instructional text attached to know how to play, what is allowed, what is prohibited, what is the objective What do you pursue, what to do in certain situations ...
-Instructions to do certain exercises or come to explain what are the rules of any sport.
-Laws and regulations. These laws are also considered instructional texts because they come to establish what to do in certain situations that may take place, what obligations or impositions are established ...
