An element with a collective reference is divided into different classes.
This include not only the class to which the concept belongs but also the basis for the classification introduced by : According to , on the bases of, etc.
Precious metals may be separated into four groups: 1) Silver and its allos. 2) Gold and its alloys. 3) Platinum and its alloys.4)Palladium and its alloys.
Answer the questions:
1.- What is the base of this classification?
2.- How many levels does it have?
3.- Use one of the ways you know to represent the classification.
BASIS OF CLASSIFICATION:
Classification is based on similarities and differences forming classes. But within these classes; we would also find differences. Furthermore, each of these subclasses could besubdivided forming categories.
There are different ways in how individuals classify and manage bits of information or real objects in the world around themselves. Information can be classified according to types, based on similar characteristics (size, color, width, texture, quality, etc) or according to a functional whole, grouped based on a singular purpose.
For example, if we take the following list:Physics, Chemistry, Biology, French, German, Spanish.
It is quite clear that we have two different types of words. We have science subjects and languages. So it is simple to divide the list into two:
Physics, Chemistry, Biology, | AND | French, German, Spanish |
When we are classifying, we often need to say what our classification is and how we are making it.
REPRESENTING A CLASSIFICATION:
Aclassification can be represented in different ways. – These are:
______________ ____________________________ __________ ____________
A. - ____________________________________
B. - ____________________________________
In English when we classify data and ideas we divide all theinformation into categories. We do these in a logical way, depending on our purpose of making the classification. Some types of logical ordering are: time order (oldest to newest); general to particular hierarchy; and scale: examples of scale are important (most important to least important), size (largest to smallest), familiarity (best-known to least-know).
READ THE FOLLOWING PARAGRAPH. CHECKTHE QUESTIONS BELOW.
Lavas may be divided into two contrasting types, acid and basic. Acid or siliceous lavas have a high silica content, about 70 to 75 per cent, and are stiff or viscous. They move slowly over the surface and solidify close to the vent. Basic lavas have a silica content of about 50 per cent. Dark colored and fluid, they flow more easily at lower temperatures and reach a greaterdistance from the crater than do acid lavas. This earth of ours, p. 3.
* What is the text classifying? Lavas.
* How many types are there? 2.
* What are the two types? Acid and basic.
* How do we make the distinction? The amount of silica present.
The markers can indicate the general division in a classification or the base of categorization. The most common are:
There are |...
