...For John Taylor Gatto, being educated and being schooled are two things different. Effectively, for him the school goal is to bring children at “the same safe level” meanwhile education could be aquired without the teacher’s help. Then, do we really need school? As John said, our schools look like prisons in which you are forced to work or without working, you will fail over and over. School is then synonymous of success; by going to school you are required to acquire the most knowledge possible for successing in your future life.Are all the people who graduate from secondary school successful? Are all the people who were or are successful such as George Washington, graduated from our secondary school? No unfortunatelly, then what is the real purpose of our schools? Would we change its system by being more flexible with what our teachers are teaching to us because mostly it is not necessarly especially in our future life. In fact, education should remplace schools; I am not saying that school is not important, it is but we should more focus on educating our children rather that forcing them to learn things they would not need things that bore them most of the time. Then, I do agree with Taylor. Nowadays, without a graduation in secondary school, it’s hard to enter into a good university, thereby hard to get a good job later. Our role upon children is to help them develop in what they really like, we have......

#### School Lunches In Schools Essay

...With our school district being mostly populated my underprivileged families, it is important to provide nutritious, healthy food twice a day. Our current food industry provider gets paid for every student they service for breakfast and lunch, so it is vital to the company to feed as many of the students as possible. 　　School lunches should be nutritious, and healthier for students. With obesity and diabetes plaguing the community, school lunches need to focus on providing the student with a balance of healthy foods that the student may not normally get at home. According to a website healthyeating.SFGate.com, 23.5 % of high school-ers eat meals from fast food restaurants. And according to the same website, high school aged girls should only consume 1800 calories per day.

#### School Violence In Schools

...1. Introduction School is a medium that seeks to promote positive direction to learners. It serves to instil knowledge and skills needed for them to contribute to their communities. However, within this positive image, it has become evident that schools are infiltrated by violence. Burton and Leoschut (2012) see violence as something which does not start in schools; or is initiated by learners only. It has come to attention that violence comes from teachers as well. In an attempt to understand the concept of violence it is essential to define it. World Health Organizations (WHO) (2002:5) defines violence as: The intentional use of physical force or power, threatened or actual, (against oneself), another person, or against a group or community,...

#### School Enviornment

...School Environment Analysis Migdalia Torres-Rosario Grand Canyon University: 575 May 14, 2014 School Environment Analysis There are many problems in schools that impact the instruction that is delivered and how children learn. According to Lecture, 2 (2012, p.2), “Understanding the environmental context of an organization can provide insight into areas that require the leader's attention, evaluation, reorganization, or support.” Therefore, it is vital for the school leadership to be aware of the issues that are occurring at the school to be prepared to impact change. Also, it is important for leaders to create committees of teachers to help address the problems of a school. When teachers participate in solving school problems, they feel investing in the school and are motivated to become leaders. One of the environmental factors that is a problem at my school is the socioeconomic issues that the students, parents, and community face. About 85% of the students at my school receive free lunch. My school is located in a poor urban community, where violence, poverty, and drugs are harsh realities. Most students have one or more family members in jail and often write essays about the police coming to their apartments and domestic abuse. However, there is very little that teachers and administrators could do to assist with this issue. One thing leaders and teachers can do is provide support and education regarding domestic abuse, gang violence, and......

Parents only want the best for their children, but it’s their children’s education that always come first. There are always controversies and arguments about which schooling benefits the student’s learning the most. Most kids are put into public schools because it doesn’t require much money unlike homeschooling or private school. Many families struggle with poverty so public schools are the only options left for them. Money isn’t the only problem that people are facing, but whether or not the students are learning going to school. Does the different type of schools really determine how much the students learn?

#### Benefits of School

...'Many young people see going to school as a chore and only go because they absolutely have to, while some will even skip school because they see it as boring and unnecessary. However, going to school is incredibly important for your career, future education you may wish to pursue, and social and communication skills. Teenagers are forever being told that they need a good education so that their can have the career they want, but many do not listen. However, it is important to remember that your schooling, no matter how long it may feel, lasts for a just a few short years compared to the rest of your life ahead of you. Therefore, it is better to sacrifice a little bit of fun now so that you can find happiness in later life, as you will be happier if you can do a job that you enjoy and afford to do the things you want. Integrally linked to your career is the fact that you will only be able to achieve a higher level of education later on if you work hard in school now. Although at the age of fourteen and fifteen many young people may not think they want to go to college or university, you don’t know how this may change as you get older. And with unemployment among young people in the USA at its highest since the early 1960′s, you may find that you need a college degree to secure a good job because there is so much competition for so few jobs. Many people also decide that they want to study further when they get a bit older, perhaps after they have got married and had children,...

#### International School

...Teaching in an International School Education plays a vital role in society and International schools today are genuinely meeting the needs of all parents willing to enroll the child. The multilingual skills that many International students and teachers possess has made possible means of nurturing and developing these skills to the optimum. The task is not easy although there is much enthusiasm for multicultural awareness and intercultural conferences. We need to have a true understanding of the many facets of international education. However, classroom teachers are confronted with the daily reality of students who are unable to speak and write grade level in English. These children need solutions and strategies to overcome these difficulties. Teachers in international schools are from different diversities as we are hired due to the efforts made by the school to hire a mix of nationalities and ages. Most are native speakers, but not all. Some schools place a very high priority on years of experience, but others are more flexible. I worked as an International school teacher for English Language and other mainstream subjects of the Cambridge Curriculum in Srilanka for the past 10 years. The school was originally for daughters of ex-pats ,diplomats , but it became a truly international school with students from 10 different countries. Many of them are actually sent there from their country of origin. I chose to teach in international schools mainly for the diversity......

#### School and Me

...went to primary school. I had no friends before I went to school. I didn’t go to kindergarten because my mother, who was a teacher, taught me at home. I learned without any classmates, I played alone and I shared my lunch with my mother only. I felt so lonely before I went to primary school. There was a school next to my home in my hometown. Every day at 5 pm, there were many students running out from school with smiling faces. Parents picked up their children and went home. I wanted to go to school like other children, chatting and playing with friends. However, I had no friends until I was 6. Before I went to school a month, I got a government letter saying I had to go to school because I was 6 which was the age to go to primary school. It made me excited. When I first went to school, I was so excited and scared. I had never met to other same age kids. I had no idea how to communicate with other kids even an opening conversation. When I was dropped off by my mother I was scared and cried. However, I was taken to a classroom by a teacher and I hid behind her. When my classmates saw that I was hiding behind the teacher, they made fun of me for a long time. I thought I would go home with a crying face but a few classmates came and talked to me at break time. They took me around to visit our school. At lunch time, some classmates sat with me and shared their lunch box with me. After school, we went home together even though my home was very close to school. They took me to...

#### B Schools

...B-schools are businesses in their own right. They have customers, stakeholders and product. In contrast to corporate business model, here profitability is not the major criterion. People are generally aware of happenings around them. MBA sharpens the way they process it so that they are able to interpret relevant information in context of the macro-environment at large and relate it to businesses. All B-schools have screening processes to select students. Accepting a candidate is testimony that the school believes in the ability of the person to be a manager. One of the first lessons taught in B-schools is SWOT for business; capitalize on strengths and opportunities, manage weaknesses and threats. If a B-school can’t help its students to apply this to his/her unique situation – the whole exercise of administering the course is futile. ‘Creativity and innovation’ need to be developed in students. To move away from the rote learning structure, all B-schools have a variety of components in their curriculum. But, has this reduced the prescriptive nature of education in India? Unfortunately, “NO” – all components have associated GPAs. Consider a case study discussion – it is observed that more points are awarded to an ideal solution (something in lines with what stalwarts like Drucker pronounced in one of their seminal works). Reading these are necessary to gain understanding; but like any medicine when overly used, it limits creativity/thinking of the students. The following...

#### School Weapons

...Miriam Herrera Sean McAuley English 1101 14 July 2015 Should school administrators be allowed to have firearms on school grounds? I think they should be able to have guns on campus. They can be allowed to have them with the proper training and the proper certification to handle a gun. Administrators who carry guns must have and maintain a handgun license; pass a psychological evaluation; and undergo firearms and emergency response training. The administrators can be allowed to have a firearm if they wish to if they wish to go that extra mile to keep their students safe. They will not be forced to have a gun if they do not wish to. With so many school shootings that have happened though out the years, I find that it will help keep the students safe. Having a gun on school campus will not stop the school shooting from happening. It will buy some time for the police to get there and handle the situation. If the teacher need to shoot the gun, with the proper training they will receive they will be able to know where to shoot and how to shoot. In order to have a gun in class the will have to keep it locked up where they only know where it is and they are the only ones to have a key to the lock. Many states are debating whether they should allow the students and school teacher to carry a gun on school campus. Oklahoma singed a bill last year where it is now legal for teachers and staff to carry guns on public school grounds. Texas just recently passed a bill allowing guns......

#### Intervention in Schools

...Interventions targeting parental involvement with the school and computer-assisted learning to enhance dyslexic students’ reading comprehension Education has long been recognised as an indispensable part of life, which serves as a platform to convey general knowledge, and develops critical skills for children to achieve their best potential. Given its value to today’s society, there has since been a leap forward in research to identify why the educational system still remains in a state of hiatus (Rumberger & Lim, 2008). The unfortunate reality of today’s economic climate for example, has been recognised to cause a divide in academic success between socio-economically disadvantaged children, from those with highly-educated affluent families (Noble, Norman & Farah, 2005). While there is some empirical evidence to support the above claims, current researchers such as Dubow et al. (2009) are now developing a more sophisticated understanding that the noteworthy disparities in academic performance, may be better explained by the influence of environmental-contextual factors (e.g. parental education, family interaction and household income). Moreover, since Cassen and Kingdon (2007) suggested that schools’ performance contributed to only 14% of the variation of low attainment, it becomes self-evident to examine the influence of family background, which has continually been suggested to be the central significant predictor of child’s cognitive abilities and their......

...RONZIE GROUP ARTICLE’S SOURCE: http://www.homeschool-companion.com/disadvantages-of-homeschooling.html Disadvantages of Homeschooling As people become more disenchanted with the current education system there has been a rise in the instances of parents deciding to homeschool their children as indicated by homeschooling statistics. This is not a decision to be taken lightly, and is one that requires a lot of research beforehand. As you will discover, there are many serious disadvantages of homeschooling. The first disadvantage of home school programs is that no matter how well designed they are they will not be a match for a nationally recognized school curriculum with examinations and accreditation. Furthermore, unless you have trained and hold qualifications as a teacher you will not be able to teach your children as efficiently as a trained professional teacher would. You want to give your children the best possible start in life and that means providing them with the education to be able to succeed in the world of work. The stress that it will place on you and your family is a strong argument against homeschooling. Not only do you have to prepare lessons on every subject, but you also need to have researched each topic enough to feel comfortable answering questions your child may have. This is a huge amount of work, and even after this, there is still the question of how to present the lessons. If the child is struggling to understand then they could blame you,......
