It allowed me to take chorus and dance along with acting. With so many classes I enjoyed taking and doing well in, my grades improved drastically.Taking all these performing art classes quickly became the salvation I needed and taught me many other burning(prenominal) lessons. But towards the end of my high school years, funds were cut from schools again. The performing arts department in my school struggled to keep the program strong with the budget cuts. By the time I graduated, a few classes were cut and the ones that were left couldnt afford the same things. These cuts affected other schools as well. For most schools across America, art programs were first to be cut.An article written by the Education Fund states that, during these difficult economic times, arts programs are the first to be sacrificed. In addition, in many schools where schoolroom space is limited, art studios are now moreover when contained in a cart that is wheeled by teachers from room to room, s everely limiting the arts rearing students receive. Although our program had not been cut, I was sad to see some of the classes go at my school among many others who enjoyed the arts. In an article written back in 2011 in the New York Times, Anna M.Phillips states, The situation is likely to worsen next year if the city goes through with its plans to layoff 4,100 teachers to save $269 million. Estimates released in February project that 350 of those let go pull up stakes be arts teachers, which would be a 15 percent drop in art, music and performing arts teachers. With all the classes being cut, students will be the first to suffer. wherefore would they cut classes that students enjoyed to come to goldbrick? The Arts gull bugger off a vital addition in education to help students become more successful.I was firsthand to witness this. The Arts allow students who dont grasp the teachings of subjects like math and English to collect in a way that is more easily understandable to them. Not all students are the same nor do they learn the same. In an article from USA Today online, Tamara enthalpy states, Schoolchildren exposed to drama, music and dance may do a recrudesce job at mastering reading, writing and math than those who focus solely on academicians. Keeping art programs in school can help students do well in school and lead to successful futures.Though it is said that careers in the arts are limited and that being an artist isnt a real job, Valerie Strauss disagrees. In article she wrote in the Washington post titled Why we love artist but not the arts education she states, Top CEOs around the world are seeking out sweet employees who can think creatively, be innovative in business development and marketing strategies and show outstanding leadership qualities that will wow clients. This is what businesses need to make do in the global marketplace.In a 2010 study by IBM, interviews with CEOs representing 33 industries and 60 countries identifie d creativity as the most important leadership skill for the future. Despite counter arguments against the arts, it is proven that it can help.

After a raise in my GPA from my performing art classes, I soon saw another raise.I noticed that I was beginning to do better in my core classes as well.

Skills learned in art programs can be used towards learning math and English and help students.

Its evident that the Arts can improve students grades and test scores.It also can improve students attendance records. The Arts for LA also states, students involved in art are three times more likely to win an award for their school attendance. I knew when I went to school that I didnt want to miss any of my acting classes because I didnt want to miss out on learning something I enjoyed doing. The arts no t only benefit students minds, but also their social and communication skills. With all of the performances to the public, its no wonder that the Arts can improve these vital skills needed everyday.When I first began performing, I was always nervous about talking in front of people. But the pure joy I found in performing made me more comfortable with public oral presentation. I remember when I was younger I had a bad habit of speaking really quickly when I got nervous. When I took acting class, my teacher made me very aware of the matter. She was constantly telling me not to rush my lines during practices. Now whenever Im speaking to anyone, I can hear my acting teachers voice in the back of my head yelling at me to slow downAs I became more comfortable being in front of people, I began to more make friends as well. The arts are a great way to bring students together and have them work together in a positive way. Henry also states, Multi-arts helps with reading, verbal and math skil ls improves the ability to collaborate and higher-order idea skills. After taking acting classes, I became much more confident with public speaking. It has also helped me to do well in job interviews as well. The communication skills that can be learned through the arts can help students interact with others.Henry also states, Drama helps with understanding social relationships, complex issues and emotions improves backbreaking thought and story comprehension. In acting classes, the teacher not only teaches you memorizes lines but teaches you to be able to comprehend that which you are reading. You learn to express different emotions and work with other people. Working with a group of people so often, your team working skills improve which is very important to a students success. As students learn something they enjoy doing, it becomes less of a chore.This makes it much easier for a student to learn discipline. Despite the lazy artist stereotypes, the arts can help motivate stud ents to do work. When I began to take dance much more seriously, I started going to practices 6 days a week. It taught me that if I worked hard enough at something, I would reap the rewards. Henry had this to say about dance, Dance helps with creative thinking, originality, elaboration and flexibility improves expressive skills, social tolerance, self-confidence and persistence. Students learn persistence not only in dance but also in other areas of art like music. Velasco states, Students who take the time to master a musical instrument learn about hard work, practice, and discipline. While performing in a group like an orchestra, band, or choir students learn to work together, appreciate teamwork, strive for a common goal, and develop negotiation skills. Students who learn discipline through art can then apply that to other fields in their lives.
