|A calculator is a great tool that allows for the mathematical exploration and experimentation and thus enhances the students understanding of concepts. Before I go into the benefits of the use of calculators in education and how to efficiently use them I would like to Maxi Pereira Uruguay Camiseta , first, state the types of calculators available today.
We can classify calculators into two types. The fist type is a calculator that evaluates expressions. This type is used to replace the manual tedious paper and pencil arithmetic. The second type of calculator is the special functionality calculator for example the graphing calculator, the algebra calculator Matias Vecino Uruguay Camiseta , the matrices calculator…etc. These calculators are used for exploration of concepts. Each type of calculator can fit in mathematics education in its unique way and needs the syllabuses to be specially written to incorporate it in education.
Recent studies show that calculators are evaluable tools for mathematics educations. Instead of the student spending his time in tedious arithmetic calculations he can spend his time in developing and understanding concepts. Many students in the past have been turned off mathematics because of the long tedious calculations and students who were efficient in these calculations were considered good at mathematics. Little attention was made to the dissolve of concepts. They hardly had anytime left to concentrate on concepts. Today with the use of calculators the students spend all their time understanding concepts and the logic behind mathematics. They can relate the concepts to real life application. The overall education experience became richer. This is why calculators are recommended for all education classes from kindergarten to college.
Some may argue that this way the student may become lazy. The reply to this question is consider you are giving a primary school student a problem that he has 100 dollars and went to the market and bought five items of one commodity for a certain price and three items of another commodity for another price and he paid the 100 dollars then what is the remainder that he will receive. Now what is the mathematical quest of this problem? Is the question here how to do arithmetic multiplication, addition, and then subtraction? Or is the question is that the student should know what is going to be multiplied by what and what is going to be added to what and at the end what is going to be subtracted from what? Of coarse the mathematics of this problem is the procedure he is going to do to find the remainder and not the arithmetic process itself. In the past overwhelming the student with the arithmetic operations made many students miss the idea and the concept behind the problem. Some others did not miss the concept but were turned off altogether from mathematics because of the arithmetic operations.
Here I have to emphasize that it is true that calculators are good for education but still one must know how to make them fit nicely in the education process. Students need to know the arithmetic hand calculations. They must study how to do that manually. When the prime concern of the mathematics problem is how to do the arithmetic students should only use the calculator to check for the answer i.e. to see if it matches his hand calculation.
So the rule for using calculators is that the teacher should check the point of the mathematics problem and the concept it is teaching. If the calculator is doing a lower level job than the concept behind the mathematics exercise than it is fine. However Nicolas Lodeiro Uruguay Camiseta , if the calculator is doing the intended job of the exercise then it should be used only to check the correct answer.
In addition, education books should write examples that use calculators to investigate concepts and teachers should lead students in classrooms to show them how to use these examples with calculators to dissolve concepts.
VALLETTA, Oct. 27 (Xinhua) -- Filfla is a tiny island situated 5km off the southern coast of Malta. It has a circumference of 800 metres Gaston Silva Uruguay Camiseta , its cliffs are 60 metres high and it has a plateau surface of 2.5 hectares. Its name is said to originate from the Arab word 'felfel', a type of pepper which has a similar shape to that of the island.
Although this minuscule island might seem to be an insignificant, barren rock within the Maltese archipelago Martin Campana Uruguay Camiseta , it actually has a very rich and storied history.
Some of its history has been researched by John Joseph Borg, the principal curator of Malta's National Museum of Natural History. Borg discovered a document dating from 1575 in which pastor Mons. Pietro Dusina visited Malta.
"In this document, I read that a parish priest was asking the Church to remove the beneficiary service from the small chapel which stood on Filfla since he was going through too many difficulties to reach it when the sea was rough Cristhian Stuani Uruguay Camiseta ," explained Borg.
The chapel is believed to have been built in the 14th century as a thanksgiving to God by a person who had been saved from a tempest after he sought refuge on the island. From then on, fishermen who were fishing nearby Filfla would attend mass in this chapel when a parish priest was present.
"The plea to deconsecrate Filfla's chapel was accepted and the triptych painting that used to adorn this site was removed and placed within the sacristy of the Zurrieq parish. Eventually, this chapel was completely destroyed when an earthquake hit the area in 1856 Giorgian De Arrascaeta Uruguay Camiseta ," said Borg.
Meanwhile, this island was also popular for its valuable natural water resource and pirates used the area as a hiding spot from which to attack approaching ships. In the 18th century, this situation became so troubling that the Knights of St. John decided to get rid of the water source by exploding it with gun powder but they did not succeed.
In fact Gaston Pereiro Uruguay Camiseta , it took 200 years of regular explosions to complete.
