Math is an important part of life. Humans cannot go through life without using math in a few form or form, whether it's counting money to pay the meal bill, adding up the money gathered in a fundraiser or calculating progress equations as a nuclear engineer. Calculators have also become an integral part of life. Calculator used in schools is a basis for debate for nearly forty years. Calculators will benefit or serve as crutches for world. They show beneficial in accelerating calculations when paying expenses and taking tests. However, they can even be a hindrance. People often become so reliant on calculators that they get started to lose the ability to perform simple mathematical equations such as fifteen times three equals forty-five. Students are damaged by calculator use to a higher degree than other people because they're in classes where they are required to calculate, problem solve, and evaluate every day. Calculators are a good idea; however, the utilization of calculators, by students in every grades, should be limited. Overuse of calculators often leads to student lack of self-confidence in mathematical skills and capabilities, a misunderstanding of the role and function of the calculator, and overdependence on calculators as tools only.

Many students and individuals, including teachers, believe that considerable use of calculators should be considered a necessity in mathematics classes. Several says, including North Carolina, now require the use of graphing calculators in the curriculum and on express tests while some allow, but do not require calculator use. Dion et al. confirmed that over "95% of colleges surveyed allowed or required calculators in their Algebra I classes, 98% allowed or required calculators in their Geometry classes, 99% allowed or required calculators in Algebra II and 99. 9% allowed or required calculators in their Pre-Calculus/Trigonometry classes" (429). Many teachers allow students to have unrestricted use of calculators in their classrooms and believe college student calculator use makes learning mathematics more interesting to students (Dark brown et al. 106). These facts indicate the views of many regarding the dependence on consistent calculator use within the class room, however, the argument rages on.

Even though many students, educators and parents argue that there should be calculator use in the classroom, they agree that use should be limited to some extent. What they do not know, is where to draw the lines. The frequent use of calculators present many potential problems in learning activities, including however, not limited by dependence, overuse, and the procedure of pushing buttons rather than doing mathematical computations. Most educators concede that calculator use should be accompanied by teaching, modeling and practice. As a future mathematics professor, I consider calculators to work when introduced and carried out properly in the class. A blend of teaching with calculator use stimulates more effective and successful applications of mathematical strategies and strategies by students.

Ineke Imbo et al. explored different mathematics problems and people to observe how elements like problem size, functions, gender, practice, skill, and calculator use influence simple arithmetic performance. It was discovered that "procedural strategies were performed faster when problem size was smaller, arithmetic skill was higher, and calculator use was less consistent (Imbo et al. 458). This substantiates the necessity for limiting the use of calculators by students. Themes in the research of Imbo et al. were researched in conditions of choosing and performing retrieval (what's known) and procedural (the procedure of working problems out) strategies by using an arithmetic skills activity, test, and questionnaire. "Students who used calculators frequently demonstrated low retrieval and procedural efficiency level but didn't differ in strategy choices (Imbo et al. 459). The results proved that students often picked good approaches for problem solving however the choice of strategy didn't always produce effective or reliable procedures or functions for handling problems, and the number of procedures determined in doing math is limited by calculator use. Imbo et al. related consistent calculator use to poor arithmetic performance for both small children and parents in this research (460). This poor arithmetic performance, increased by frequent calculator use, often prefaces mathematically related self-assurance issues in students.

Many students have a problem with math and develop a dislike for it because they lack self-assurance in their mathematical skills. Unrestricted use of calculators frequently helps build a sense of inadequacy or give students a wrong sense of self-assurance (Porchea 118). Calculators aren't designed to, and cannot, solve all mathematics problems in classrooms despite the fact that many people think so. Dion et al. reported in her studies that "few items on the professors' tests actually required calculators to resolve" the issues (433). Since checks do not echo the necessity for calculator use, it is degrading to expect students need calculators to be able to execute mathematical businesses. This abasement of ability lessens the assurance levels of students in mathematical functions. Lack of self-assurance mathematically is compounded by self-confidence issues in undertaking computations with calculators.

Research also implies that students are often uneasy using calculators. Berry and Graham examined students' keystrokes on calculators as they required assessments (143). They found that students didn't "create schemes or ways of working that included the calculator" (Berry and Graham 143). Even though there were problems on the tests that required certain types of computations within the power of the calculator, key heart stroke analysis proved "without any evidence of these being done on the graphics calculators" (Berry and Graham 143). When students were interviewed and asked concerning this they replied that "while they recognized how to use the calculator to carry out statistical tests, they did not feel totally self-confident by doing this" (Berry and Graham 143). Berry and Graham's research discloses that students who lack calculator knowledge, skills and confidence lack the same in regards to math. It has many implications for teachers.

Porchea's study mentioned that teachers spent an abundance of time reassuring students on their use of calculators and providing precise explanation related to students' completed tasks on the calculator (50). Quesada studied seven hundred and seventy students in college pre-calculus classes (206). The control group research required the utilization of clinical calculators and a normal math e book. The experimental group used one type of graphing calculator and a textbook created for graphing calculators. The experimental group have scored higher on the final exam than the control group. Results of the study argued that the utilization of the graphing calculator and designed textbook facilitated understanding, provided capability to check answers, and preserved time. However, the students that used graphing calculators performed marginally worse in the class than in past math classes (Quesada 212). Students voiced that these were concerned that while there have been advantages to graphic calculator use, they did not feel prepared for the next level math course and sensed they were too dependent on the use of calculators in course. This demonstrates students' insufficient confidence in calculator applications and their talents to compute mathematical problems, even when receiving instruction on calculator use and integration of calculator skills in classes. Students must learn to use calculators to the fullest amount to benefit from the technology. THE IDEA of Instrumentation, released by Berry and Graham, discusses calculators as tools or tools (141). If, when utilizing a calculator, students incorporate techniques to solve problems the calculator becomes a tool utilized to complete an activity. Whenever a "scheme" or plan is constructed by students while using the calculator, it evolves into an instrument (Berry and Graham 1044). The difference between students using a calculator as an instrument or tool shows whether they understand the functions of the calculator. They utilize this knowledge to plan and strategize a solution to issues (device use) or they might be calculator smart and know every one of the right keys to motivate to get an answer (use as a tool). When students are using the calculator as a musical instrument they are really creating a remedy to a challenge. Students often view calculator activities to be completely different from mathematical computation and problem solving. Most students use calculators as tools. Professors should expect and demand calculator use as a musical instrument in their classrooms. When calculators are used as equipment, students demonstrate knowledge of how the calculator works and what it can do.

Berry and Graham studied twelve students as they done a set of two jobs and found, through their keystrokes, "that the students were too reliant on the calculator without knowing many of the anomalies it could generate" (146). No design or plan was evidenced by their keystrokes, because the students didn't create ways of working that designed the use of the calculator as a musical instrument (Berry and Graham 142). Students utilized the calculator as an instrument to find a remedy, not as a musical instrument to devise an idea to solve a challenge. In Berry and Graham's studies, use of the calculators as tools impacted the students, but unfortunately student knowledge and understanding never impacted how the calculators were used (142). Data from McCulloch provides data that lots of students perceive the graphing calculator to be always a "tool that is important because of its ability to lessen the thinking involved in solving an issue" (43), and they also consider calculators to be reliable tools in dealing with problems quickly (McCulloch 87). The use of a calculator offers students a number of powerful new learning and problem solving strategies, but as an instrument, it diminishes the necessity for the scholar to get a high degree of skill in image manipulation (Katsberg and Leatham 29). Students must understand calculators to utilize them as tools to find ways to solve mathematical problems.

Whether calculators are used by students as tools or musical instruments, they are just as smart as their users and can only just perform functions when manipulated to take action. Therefore, students must understand the role and functions of the calculators to utilize them effectively and proficiently. The lack of knowledge about the functions and problem-solving techniques of calculators often ends in student misuse and mistakes. While students know the essential operations of calculators, they are not aware of the special functions, secrets, and features calculators have, or the role of these in the utilization of the calculator to resolve problems. Students rarely exceed the features of the calculator to explore the probable or constraints of the technology. Berry and Graham discovered that students in their circumstance studies were unaware of lots of the top features of the calculators even though they had usage of and used calculators every day in category. The students also made problems that would not have been made without the utilization of any calculator. The advanced functions of calculators, such as display screen size and trigonometric functions, were never explored by the themes in the studies of Katsberg and Leathman (27). For instance, the students were required to graph a function and because they didn't know to change the display screen size of the calculator they graphed the incorrect work as their answer. They recognized what the function should look like but because the calculator exhibited them differently, they assumed the calculator was appropriate. If they acquired a working knowledge of the functions of the calculator, the students would have recognized to change the display screen size. If they could have graphed the function by hand, they would have came to the realization their oversight. In Katsberg and Leathman's research, graphing calculators were found to be used predominately to check algebraic alternatives, find solutions graphically, and to graph functions. When students understand the role and functions of calculators, these are comfortable using strategy and applications to resolve mathematical problems.

Katsberg and Leatham's research also reveals that students become lost and overwhelmed as they attempt to integrate their understanding of mathematics with the developing understanding and use of any calculator (28). Brown et al. mentioned through their research that educators of high mathematics courses be anxious that calculator use by students may be a way of getting answers without understanding mathematical processes (102). A lot of the time students do not use prior knowledge to solve problems using the calculator. "When using a graphic calculator the students appeared to have ignored what they learned when they first began plotting graphs" (Berry and Graham 146). There's a wide range difference in the capability to solve a difficulty utilizing a calculator and the use of knowledge and skill to solve mathematical problems through critical thinking and calculator applications.

Berry and Graham found, through the keystroke research, that students often adopted a button pressing experimental technique to solve problems rather than understanding the process (147). Dion et al. reinforced this by concluding that "The advantages of calculators into the curriculum automatically invites students to learn keystroke somewhat than ideas" (433). It is important to distinguish between calculator skills and the numerical capacity of students. The necessity for students to regularly jot down their work and echo, rather than just get the answer to a problem, stems from this insufficient pupil understanding in just what a calculator can do and exactly how it can be used. Quesada et al. detected that students tend to automatically begin to try to graphically solve problems instead of handling them algebraically when calculator use is allowed in classes (213). Students who had been interviewed in McCulloch's case studies indicated that "calculator use is a security world wide web kind of thing" providing an opportunity to plug- in quantities to find answers when needed (2). Here are some is a incorrect sense of security regarding mathematical talents and skills. Calculator use does not ensure that a learner is mathematically efficient just like the capability to do math does not reveal strength in calculator skills

My experience going right through school supports my argument that calculator utilization in universities should be limited. Throughout my middle institution years we were allowed to use a TI-15 brand calculator. Somewhat more advanced than a technological calculator, it allows for computing and simplifying fractions and using percent signs or symptoms. We rarely used them in course or on homework assignments. Due to the limited use of the calculators in middle institution, my Algebra I style within my freshman yr of senior high school was a breeze. However, as a tenth level high school student, TI-83 calculators were required. TI-83's, available in every classroom, were used every day from that time forward in my own high school profession. Usage of a calculator all the time, fostered a reliance on utilizing it for adequate the work I did so. When I attained North Carolina State University I used to be shocked that we was not permitted to use a calculator in my math classes. Within my Calculus I class last semester, calculator use was not allowed in school at all, for any reason. Small calculator use has prolonged this semester in my own Calculus II category. I often find myself needing to re-study certain areas of mathematics because I became so dependent on my calculator in high school. It was, and it is not, a simple move to make. College mathematics professors move through material quickly and offer little review time in school. More research should be done to effectively present how calculator used in schools is affecting students, independently and as a whole, from enough time of transition from middle institution to senior high school and through graduation from high school.

Calculator use should be limited due to the many problems students face when using them. Even with the NEW YORK Department of General public Instruction's mandate of calculator use in the classrooms, limited use could be easily executed. Instructors could assign calculator inactive homework and force students to show all their work. Another option would be to make assigned checks calculator inactive but allow time for students to utilize the calculator to check on their work once they have completed the test. Students might also be required to show all of their work on lab tests and quizzes with the calculator available to them for use. Restrictions could be arranged on calculator use by not allowing the calculators when students are learning new material. Checking use the calculator after quizzes, where calculator use is prohibited, may provide a great teaching instant as students commence to learn how they can check their work or perform these tasks effectively on the calculator while reflecting on the completed work.

The use of the calculator can cause negative effects, but is not usually dangerous until students become centered and think they can not accomplish mathematical responsibilities and testing without them. If educators do not require students showing their work regularly, then they cannot promise mastery of skills in mathematics. Also, instructors cannot expect their students to state mastery of numerical skills. While using constraints above, or if educators design their own creative constraints, the students' mathematical potential will be even greater than what it happens to be. It cannot damage to limit the use of calculators; it'll simply help improve college-bound students' skills as they go into college. It will also improve the knowledge and mathematical skills and talents of those who are graduating and entering the military or workforce. This might better promote the goals of high colleges, to get ready and instruct skilled, internationally aware, and "future ready" students for tomorrow. Calculator use in universities should be limited by better ensure that students have mastery of skills without reliance on sources apart from themselves in preparation for today's and future.
