From Latin curvus, a curve is a line (real or imaginary) that deviates from the straight direction without forming angles. This means that its direction varies gradually and constantly.
The concept is often used to name the curved section of a path, a road, an automobile circuit or a railroad track. For instance: “To get to the museum, you have to continue along this street and, when the curve comes to the right, travel another two hundred meters”, “The Ferrari driver lost his way on the steepest corner of the circuit and ended up out of competition”, “The mountain routes are quite dangerous as they have many curves”.
In these cases, especially when they are used to refer to the intersection between two streets of a town, it is understood that it is not a proper curve, since an angle is formed (or more than one, depending on the precision with which it is observed). The most appropriate term for this concept is “corner.”
There are various types of curves. The open curves They are those whose extremes do not meet; On highways, they are those that have little curvature and that vehicles can take without reducing their speed. The parable and the hyperbola are examples of open curves in the realm of mathematics.
The tight curvesInstead, they go back to where they started. On roads, hairpin turns have great curvature and must be taken very slowly. Examples of this type of curves are circumferences and the ellipses.
A curve can also be a line that graphically represents the magnitude of a phenomenon according to the values adopted by its variables. A precipitation curve can reflect the level of precipitation in a certain territory in a certain period of time. The X-axis (horizontal) can show the different months, while the Y-axis (vertical) can show the rainfall in millimeters.
The learning curve, on the other hand, is a concept that serves to measure the success that is obtained over a period of learning. It is usually graphed as follows: the X axis shows the time that has elapsed from the beginning to a particular point, while the Y represents the number of correct answers made in that period.
In general, when a new task is undertaken, errors are very common, and they disappear with the weather, until the curve becomes a straight line. However, there is the possibility of obtaining random results, which shows false learning, a serious retention problem or great difficulty in evoking the concepts learned.
Economists rely on the concept of a learning curve to explain productivity and quality growth after making certain alterations to a process (such as personnel changes, acquisition of new tools or adoption of new methodologies).
In the case of the gaming industry, specifically video games, the learning curve is used to describe the difficulty that a product presents for the average of the players and the time it takes them to overcome the initial barriers, until they settle in and feel confident that they can control it with ease.
The steeper the curve, the more efficient is the learning in a given period. Some of the factors that affect a student’s performance are as follows:
* the set of skills related to the subject that you are willing to learn and the previous knowledge you have;
* the methods used by teachers, or by the student himself (if he is self-taught);
* the context in which learning takes place (both physical and mental issues).
