Therefore, appropriate use of computers in mathematics instruction may deepen mathematical understanding Tall, Computers may be used for work with various mathematics concepts, including formulas, constructions and proofs, and it can also be used for accessing information and communicating with others mathematically Wiest, Whatever the uses of computers in mathematics, the focus should be on higher order thinking with an emphasis on inquiry, reasoning, and engagement in worthwhile mathematical tasks Wiest, Otherwise, if students use computers as calculators for even simple mathematical problems, their thinking ability may be limited.

Educational software in mathematics education can be classified in five categories Arslan, :. In Turkey, in the latter elementary mathematics curriculum, it is clearly stated that students can do interactive investigations on dynamic geometrical shapes formed in different dynamic geometry software MEB, a. One of the most popular computer software with that property is GeoGebra. GeoGebra is dynamic mathematics software for all levels of education that brings together geometry, algebra, spreadsheets, graphing, statistics and calculus in one easy-to-use package URL1.

Being an open source software under the GNU general public license, GeoGebra is a dynamic mathematics software for teaching and learning mathematics from middle school through college level, and it is as easy to use as dynamic geometry software but also provides basic features of computer algebra systems to bridge some gaps between geometry, algebra and calculus Hohenwarter and Preiner, GeoGebra provide to see graphical, numerical and algebraic representations of mathematical object on the same screen.

Therefore, different repre-sentations of the same object are assembled dynamically and any change in one of these representations is automatically transformed to the other ones. The basic objects in GeoGebra are points, vectors, segments, polygons, straight lines, all conic sections and functions in x and with GeoGebra dynamic constructions can be done like in any other dynamic geometry system Hohenwarter and Fuchs, These constructions may be altered dynamically by dragging free objects and furthermore, it is possible to enter coordinates of points or vectors, equations of lines, conic sections or functions and numbers or angles directly Hohenwarter and Fuchs, Shortly, GeoGebra is an open source dynamic mathematics software that can be used at any level of mathematical instruction.

As seen in the literature, there are some studies about trigonometric functions, their conceptual meanings and operations with these functions. In contrast, few researches have found the concept of the periodicity of trigonometric functions Dreyfus and Eisenberg, ; Shama, This concept is taught as a value that can be calculated at the end of some algebraic operations, and it is rarely associated with its visual representation Weber, Therefore, based on the fact that students may have difficulties because of the operational teaching of the concept of the periodicity of trigonometric functions, the aim of this study is determined and to investigate the effect of GeoGebra in the teaching of the concept of the periodicity of trigonometric functions.

The participants of this study are 36 tenth grade students from a public school in Istanbul. The students were divided in two groups control and experiment according to their classrooms. Thus, post-test control group modal has been chosen. In this study, a post-test is used to investigate the effect of GeoGebra on the explore process of the periodicity formula of the trigonometric functions. The participant students filled the test approximately 15 days after the course.

The post-test consists of five conceptual and operational questions about the periodicity of trigonometric functions Table 1. This research is conducted with two classes of tenth grade students from an industrial vocational high school. These classes have equal classroom size of 18 students. Their academic achievement can be considered at the average level but some students have low skill level of calculation.

In one of the classroom, the course is done with GeoGebra assisted mathematics instruction where students only followed the teacher who used GeoGebra for demonstration and drawing graphs, whereas in the other one, the expository teaching technique is used.

In both of the two classes, the same teacher conducted the courses. The post-test questions are examined separately for two class-rooms. For every question, the frequencies and percentages were calculated and presented. The findings of the study are summarized in Table 2. The answers of students in the control group are coded as:. Correct answers: 11 students claim that a period is a repetitive pattern and give examples from real life.

Partial correct answers: 2 students state that a period is the time passed for the formation of a sound wave. Incorrect answers: 2 students try to give an explanation with regard to the periodic table, and 2 students give no sense explanations with respect to the subject. Correct answers: 14 students claim that a period is a repetitive pattern and give examples from real life. Incorrect answers: 1 student claim only that the period is something related to the trigonometry but he did not.

Despite the fact that students filled in the post-test after two weeks of instruction, they still remember the definition of the periodicity. If a increases, the period decreases. Correct answers: 13 students give the same correct answer of the students in the control group. These findings show that there is a difference between the percentages of correct answers in the two groups.

Correct answers: 14 students used the formula correctly, and did not make any calculation error. Thus, it can be deduced that these student memorized the formula but he did not understand conceptually. Correct answers: 14 students used correctly the formula and did not make any calculation error. Partial correct answers: 4 students either confused the formula or made some calculation error.

Hence, students are very successful at using a formula to answer an algebraic question. Correct answers: 1 student used correctly the formula, and did not make any calculation error. Partial correct answers: 8 students either made calculation errors or confused the value of a.

The low level of skill of four operations in fractions may be considered as the reason of these mistakes. Thus, it can be deduced that this students memorized the formula but he did not understand conceptually. Partial correct answers: 2 students made some calculation error at the last step where they divided two fractions.

Incorrect answers: 1 student wrote correctly the formula but he did not make any calculations, he did not replace the numbers with the letters. Thus, one can deduce that this student memorized the formula without understanding it. The deficiency or the low level of skill of interpretation of graph may be the reason of these mistakes.

Based on the findings of the study, for the question of the periodicity of a trigonometric function in algebraic form question 2 of the post — test , the number of correct answers of the students that participated in the GeoGebra assisted mathematics instruction is much higher than the students that participated to expository teaching. Even if the students in the control group remember correctly the formula of the periodicity of a function, they do not understand sufficiently the meanings and the effects of numbers in the formula.

The reason behind this gap may be the fact that, as Ross et al. Most of the students in the experimental group both remember correctly the formula and explain clearly the effects of the numbers a, n and b in the formula. Hence, they understand conceptually the periodicity of the trigonometric function as these students explored by themselves the formula during the course. GeoGebra gave them the opportunity of conjecturing the formula.

Therefore, students learned conceptually and formed their own mathematical knowledge. So, they remembered easily the necessary knowledge. This result is similar to the experimental study of Zengin et al. Furthermore, the result of this study about the efficiency of GeoGebra on the learning of the periodicity of trigonometric functions is very similar to the experimental studies done by Blackett and Tall , Autin , Choi-Koh and Mafi and Lotfi about the efficiency of different technologies on trigonometry teaching.

According to the findings of the study, for the question of direct application of the periodicity formula question 3 of the post-test , the number of correct answers of all students is very high. This result may be originated from the fact that, as Weber also explained, this concept is taught as a value that can be calculated at the end of some algebraic operations, and it is rarely associated with its visual representation.

In addition, the finding that students in the experimental group answered correctly as much as the control group students shows that GeoGebra is useful not only for conceptual learning but also for operational learning. In other words, students may improve their skill of operation by the effect of GeoGebra assisted mathematics instruction. Hence, it can be deduced that better learning conceptually provides better making calculations.

The findings for the fifth question of the post-test reveal the fact that students have difficulties in interpreting the graphs of functions. Even if the number of graphs drawn in the course with GeoGebra is higher than the traditional mathematics course, students in experimental group give also wrong answers for that question. The dominance of algebraic representation in mathematics teaching may cause the difficulties in interpreting graph.

In other words, since multiple representation of the periodicity of trigonometric functions is not used often and efficiently in courses, students can explain the meaning of the period in algebraic form but not in visual form. However, the number of students in the experimental group that give correct and partial correct answers for this question is more than in the group.

This result yields that, about the graph of trigonometric functions, GeoGebra assisted mathematics instruction is more effective than traditional teaching techniques. As a result, in this study whose aim is to represent GeoGebra as an alternative way of teaching of the periodicity of trigonometric functions that is usually taught algebraically not visually, GeoGebra assisted mathematics instruction is more effective than traditional expository mathematics instruction.

The results of the study may be considered as favorable because the high school type of the working group students is not preferred often by the researchers and the mathematics achievement of students from this type of high school has been found as low Mumcu et al.

It is recommended that some researches about this concept have to be conducted with students from different type of high schools, and also with pre-service teachers in universities. According to the results of this study, in mathematics instruction with expository teaching techniques, the relationship between the algebraic form and the graphical representation is often ignored.

Therefore, this observation emphasizes one more time that multiple representation of any concept must be always presented in courses. Furthermore, in order to decrease calculation errors in basic operation, in the elementary mathematics education, the skill of operations should be improved.

Where was the theorem used in their societies? In "Geometry and Algebra in Ancient Civilizations", the author discusses who originally derived the Pythagorean Theorem. He quotes Proclos, a commentator of Euclid's elements, "if we listen to those who wish to recount the ancient history we may find some who refer this theorem to Pythagoras, and say that he sacrificed an ox in honor of his discovery".

If this statement is considered as a statement of fact, it is extremely improbable, for Pythagoras was opposed to the sacrifice of animals, especially cattle. If the saying is considered as just a legend, it is easy to explain how such a legend might have come into existence.

Perhaps the original form of the legend said something like he who discovered the famous figure sacrificed a bull in honor of his discovery. Van der Waerden goes on to comment that he believes the original discoverer was a priest, before the time of Babylonian texts, who was allowed to sacrifice animals and also was a mathematician. This question can never be answered, but evidence that societies used the theorem before the time of Pythagoras can be found.

The Theorem is useful in everyday life. For example, at a certain time of day, the sun's rays cast a three foot shadow off a four foot flag pole. Knowing these two lengths, and the fact that the pole forms a ninety degree angle with the ground, the distance from the end of the shadow to the top of the pole can be found without measuring. The first step is to substitute the given data into the actual formula. Now you can find from the length of the third side, which is five feet.

Trigonometry is basicly the study of the relationship between the sides and the angles of right triangles. Knowing how to use these relationships and ratios, is absolutly necessary for almost everthing. It might not seem like it, but trigonometry is used almost everywhere. Another example of the importance of the theorem is the world orb symbol, which depicts engineering studies. Although there are many parts to this symbol, the Pythagorean theorem is appropriately at the center, since much of engineering, mensuration, logarithms etc.

Trigonometry Trigonometry uses the fact that ratios of pairs of sides of triangles are functions of the angles. The basis for mensuration of triangles is the right- angled triangle. The term trigonometry means literally the measurement of triangles. Trigonometry is a branch of mathematics that developed from simple measurements. A theorem is the most important result in all of elementary mathematics. It was the motivation for a wealth of advanced mathematics, such as Fermat's Last Theorem and the theory of Hilbert space.

The Pythagorean Theorem asserts that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. There are many ways to prove the Pythagorean Theorem. A particularly simple one is the scaling relationship for areas of similar figures. Did Pythagoras derive the Pythagorean Theorem or did he piece it together by studying ancient cultures; Egypt, Mesopotamia, India and China?

What did these ancient cultures know about the theorem? Where was the theorem used in their societies? In "Geometry and Algebra in Ancient Civilizations", the author discusses who originally derived the Pythagorean Theorem. He quotes Proclos, a commentator of Euclid's elements, "if we listen to those who wish to recount the ancient history we may find some who refer this theorem to Pythagoras, and say that he sacrificed an ox in honor of his discovery".

Thales used multiple formulas in geometry to predict the solar eclipse.

Anaximander was credited with being first to try to attempt a map of the world. He also was accredited with an explanation of the origin of the Earth. The theory was that when the heat and the cold begin to separate, the ball of fire becomes surrounded by mist. One of Archimedes most famous works is Measurement of the Circle. He discovered this by circumscribing and inscribing a circle with regular polygons with 96 sides.

He also was the founder for the relationship between volume, mass and pressure. The rules and relationships are the basic foundation to many of today's inventions. The Scientific Revolution was the transformation of how people viewed the universe. Newton used his knowledge with previous astronomers, like Galileo. This system was adapted by the Romans in their roman numerals. Egyptians also has the Rhind papyrus containing math related brainteasers for instance.
