In the school curriculum, a lot of attention is paid to the study of the topic "Object and its features" already in the 6th grade. Children gradually learn to characterize most of the phenomena, objects and events around them.
This skill is also important because this concept is one of the basic concepts in modern information technology. Schoolchildren must learn not only to call by name, but also to highlight the main, most important features of an object, computer science provides clear, structured knowledge.
Definition
Every element of the world around us (living and inanimate objects, natural phenomena, any processes), which can be perceived as a whole, is called an object.
Accordingly, objects have names by which they are distinguished and remembered. The world is arranged in such a way that every detail in it has a name, otherwise it would be difficult for a person to navigate the surrounding reality.
Views
Computer science divides objects into three main groups:
- Objects (book, pencil case,tree, car).
- Processes (singing, walking, drawing).
- Phenomena (earthquakes, snowfall, dawn).
I would like to separately mention objects - elements of the interface of the operating system. These are files, folders, icons or shortcuts - all of them are executed graphically and individually. That is, each has its own icon (image). Their properties are usually studied through the context menu, which can be called by right-clicking on the icon.
Name
Whatever the main and most important features of the object, the name is always given at the beginning. Every object has its own "name". Usually it answers the questions "who is this" or "what is this". The variety of forms and possibilities of the language sometimes makes it possible to endow objects with many names. For example, a house is a building, structure, structure, building, etc.
Next. Names exist in a generalized form and in a specific (personal or personal). For example, the "tree" object is a fairly common name. There are a lot of trees on the planet. But the name "larch" is specific, belonging to only one species.
Signs
Mandatory for any element of the surrounding world is the presence of its own characteristics. These are the main and most important features of the object. Let's take a closer look at them.
- Properties are the characteristic features that significantly distinguish it from all others. The main parameters of a property are some existing value and its possible values or states. Example, apple - round, red, sweet.
- Actions is an important feature, it shows what an object can do and what are the possibilities for manipulating it. For example, candy, it can be unwrapped, eaten, gifted, etc.
- Behavior is a sign inherent in many objects, characterized by discreteness of actions, an algorithmic set of certain operations performed by it. Let's take flight as an example. Many birds can fly, but so do airplanes and rockets and insects. They do it in a unique way, according to their own algorithm.
- State is a set of specific values that together describe an object at a given moment in time. That is, with a different symbiosis of input data, the object will be characterized differently. Example: the weather is windy (or sunny, rainy). A combination of conditions will constantly "move" here: air temperature, humidity, precipitation, atmospheric pressure and others.
Conclusion
You can practice and independently name the main, most important features of an object from the surrounding world. It can be anything - a bridge, a river, an ocean, a city, an eclipse or a flood.
Such practice in computer science lessons in high school will help to assimilate the material and enable students to learn how to structure any phenomena in their minds. In further training, they will have to deal with programming, where the object and its properties will be the basic concepts when working incertain environments.
