What Is Calibration in Chemistry?

What Is Calibration in Chemistry?There are several questions regarding what is calibration in chemistry. It is the examination of the material samples for results. The material samples are that used for calibration testing, which has a slightly different content from that in which the sample was analyzed. The difference is that it must be known to be identical and that the differences do not need to be added up.One may come across many problems if the difference is left out and one cannot get the same effect for an effective result. However, with the aid of calibration in chemistry the quantity is tested and found to be the same or similar to the experimental results.The results are correct but in the sense that the substance is similar to that in which the testing is done, but the amount is different. This happens when the original composition of the substance is quite different from that in which the material was tested. This is called impurity or contamination.Laboratory of any re search or company will use this substance for the testing and checking the chemical composition of substances and also their properties. When the amount of impurities is small and the contents are standardized the result of the test may be accepted as proper. However, if the impurities are large then the result of the test is not valid.The situation is reversed with the impurities which are large. They are going to affect the result. This is known as the impurity. It is only in laboratories where there is constant checking of the substances that such impurities are recognized and there is a way to correct the difference.In order to check one's test results, one will have to take some time to understand the process. By learning about the chemistry involved and practicing, one can have a better idea about the facts. A few simple things will help one in getting a good idea. The problem with calibration in chemistry is that people seem to underestimate the importance of knowing the impu rities.However, it is useful to know what they are before they are used. Knowing them and being able to correct them can make the results of the test very accurate. It is even more important to use the right quantities of substances in the test so that the results are accepted without error.

Should Schools Teach Character

Should Schools Teach Character Americas schools are having a difficult time simply teaching students how to be proficient in reading, math and science. Thats why many schools completely ignore teaching basic character skills. Most schools do not effectively teach behavioral skills and proper attitudes/manners like cooperating, being on time, making eye-contact, speaking persuasively, etc, argues Jay Mathews in an article in the Washington Post. Some schools are trying to incorporate these basic skills into education, a practice known as character education; however, many schools are still ignoring them. Very few schools have actually made progress in character education, argues Mathews. Mathews cited a study in social and emotional learning (SEL education) that trains students to act and think in positive ways. The study suggested that strong SEL education can create better student achievement. However, the data does not yet measure effects on students lives and work after high school graduation. Students in social and emotional learning classes improved their test scores and grades by 11 percent, compared to similar students in standard classrooms without SEL education, according to the Impact of Enhancing Students Social and Emotional Learning: A Meta-Analysis of School-Based Universal Interventions study, by Joseph A. Durlak and Kriston B. Schellinger of Loyola University Chicago and Roger P. Weissberg, Allison B. Dymnicki and Rebecca D. Taylor of the University of Illinois at Chicago. The authors of the study determined that these results were significant. They also found that students in SEL education have better social skills, less emotional distress, less misbehavior (bullying or suspensions), more positive behavior and ultimately better attitudes. These effects continued for six months after the programs ended. SEL programs are successful at all educational levels (elementary, middle and high school) and in urban, suburban, and rural schools, although they have been studied least often in high schools and in rural areas, reads the study, according to the Washington Post. The authors stated the SEL education helps students become more confident in their learning, and thus try harder and rarely give up on more challenging concepts or classes. SEL education students are also self-motivated, setting high academic goals and constructing a personal, effective approach to learning. Other studies are contradictory. One from the Institute of Education Sciences suggests that seven of the most popular SEL education programs did not produce significant social or academic gains. Another study, the Child Development Report, suggested similar results, also stating that SEL education does not necessarily produce better attitudes and behavior. SEL education produces better results in smaller classrooms, especially when a teacher takes on the approach for one class, according to Mathews. School-wide comprehensive programs are more complicated to implement, causing problems and limiting their positive effects.

Brasil, eventos e o Inglês

Brasil, eventos e o Inglês Com todos os eventos que o país irá cediar pelo próximos anos Copa das Confederações, Jornada Mundial da Juventude, Copa do Mundo, Olimpíadas é imprescindível que quem trabalha com o público tenha um conhecimento, ainda que básico, do Inglês. Isto, porque como se sabe, o Inglês é um idioma internacional, usado em todo o mundo para facilitar a comunicação entre pessoas de culturas diferentes.Foto: Márcio Luiz Rosa/ O Globo e Isabela Marinho/G1No entanto, com a proximidade destes eventos, vemos deslizes como o caso das placas erradas no Rio de Janeiro, que demonstram um descuido para com os preparativos. É certo que das 300 placas instaladas, apenas duas continham erros. Porém, tendo em conta da magnitude das atividades que o Brasil irá albergar, seria de pensar que, antes da instalação das placas, alguém que fale Inglês teria acesso às mesmas e fiscalizaria esse material, de modo a garantir que nenhuma gafe fosse cometida. Afinal de contas, o mundo inteiro es tá prestando atenção. Nesse caso em específico, o órgão municipal responsável garantiu que a reposição das placas com a grafia errada não iria gerar novos custos, mas o mal já está feito, a imprensa, nacional e internacional, já noticiou o acontecido.Existem diversos grupos que são contra a realização destes grandes eventos no Brasil, inclusive, ainda esta semana, ativistas formalizaram uma queixa de violação de direitos humanos contra o Brasil na ONU, por causa das pessoas que estão sendo desalojadas para a construção de infraestruturas para a Copa e outras situações consideradas abusivas. Sem falar que ontem (30/05), a justiça do Rio suspendeu o amistoso Brasil x Inglaterra, que seria no Maracanã, alegando falta de segurança para o público. Contudo, mesmo com todas estas situações, não existe nenhum indício de que algum dos eventos será cancelado. Portanto, estar preparado para a recepção dos turistas é um dever.Seja para quem trabalha diretament e com o público ou para quem irá chefiar equipes, que estarão lidando com pessoas de outras nacionalidades todos os dias durante a realização dos eventos, saber falar outros idiomas de preferência, pelo menos, Inglês é fundamental. Daí que esteja a ocorrer uma corrida às escolas de idiomas, mas os cursinhos intensivos não conseguem ensinar tudo, especialmente se você nunca teve um contato regular com a língua.Quem quer estar com o Inglês na ponta da língua precisa se preparar, seja com aulas intensivas de conversação, cursinhos de idiomas ou quaisquer outros meios disponíveis. No entanto, nessa busca por estar pronto na hora que tudo começar, é preciso ter em mente algo essencial: invistam em algo que seja útil no futuro, não apenas para os eventos, mas para a sua carreira como um todo. Não aprendam o idioma apenas para a Copa, aprendam para vocês mesmos, para as suas carreiras, para a vida, pois só assim o investimento valerá a pena. Boa sorte!

Working hours for UK Teachers - Tutor Hunt Blog

Working hours for UK Teachers Working hours for UK Teachers amongst the longest hours in the world Working hours for UK Teachers amongst the longest hours in the worldSchoolsA recent study published by the Global Teacher Status Index shows that teachers in Britain are working more hours per week than nearly anywhere else in the world. The global study found that UK teachers work around 50.9 hours per week ? that`s more hours than teachers in any other country in the survey, with the exception of Singapore, Chile and New Zealand. The study also polled members of the public, asking them how long they thought the average teacher`s working week was. The results came back at 45.9 hours, showing that most people grossly underestimate the time teachers work. I know from experience that some teachers work far more than this - my partner is a teacher, and certainly spends more than 50 hours a week at her school; and then of course there is all the time she works at home, marking students` work and composing lesson plans. I also know socially many teachers who work throughout London, and they all calculated that they exceed 50 working hours a week. Many people would say this is not a particularly excessive amount: if you want to progress in your career you have to be willing to put the hours in. I`ve worked in telecommunications, and the financial sector, and there were some years where I`m certain I pushed past the 60 or 70 hours a week. It was hard work, certainly, but I was determined to progress, to climb the ranks, and to be financially rewarded. In teaching however, there really is an upper bound on what you can earn. Unless you become a head of a school, your pay`s capped at a boundary far lower than you would ever encounter in the private sector. Despite their relatively low pay the study actually revealed the British public significantly overestimate the starting salary of teachers, believing them to be earning around ?29,000, when in fact a newly qualified teacher generally only earns around ?24,000. Somewhat hearteningly the report also indicated that the public think the starting salary of teachers should be far higher: around ?31,000. Back in 2013 a similar poll showed that more than three quarters of the public were behind some form of performance related pay for teachers. Opinions seemed to have changed during the five year interim though, with only a third of those being polled in the new survey supporting this kind of variable pay scheme. Getting back to the topic of long working hours though - unless you live with a teacher, I really doubt anyone could comprehend the amount of work their job demands. My partner is a science teacher in a London secondary school. She`s at work every weekday for 7:30am, and rarely leaves before 5pm - this schedule in itself is not particularly onerous, but at least once a week there is some kind of extra activity, such as a parents evening, or some kind of meeting, which usually continue past 9pm. Added to this is the gargantuan amount of work that she does at home: planning, marking, lesson plans - this prodigious amount of paperwork (and our home is full of paper and files and textbooks) is attended to every evening, and for a large portion of the weekend. An obvious counter to the claim that teachers are grossly overworked is that they are compensated with a huge amount of holidays - typically around 13 weeks annually. No one can deny that this is a very generous amount of holiday le ave - but I can tell you that for a portion of every break, summer, Easter and Christmas, my partner spent a significant amount of time working at home. Many teachers complain that they spend as much time being in-school social workers, dealing with unruly pupils, as they do actually teaching. Only this week the department of education has pledged to assist schools in this area, promising that they will simplify the way teachers are required to log and record poor behaviour. I suspect that the teaching profession is becoming hampered by the same bureaucracy that the police force is suffering from: being required to create encyclopaedic logs of every incident, and every single misdemeanor, however large or small it is. The Department for Education have just published a report by the Workload Report Advisory Group, which cautions how teachers are at risk from `anxiety and burnout` due to the growing about of paperwork relating to pupils` behaviour. We rely on teachers to produce every new generation of employees - if we put them under too much pressure, if we obstruct their ability to actually teach, and fill their lesson time with excessive bureaucracy, we will be directly reducing the quality of education our future workforce will be receiving. 15 months ago0Add a Comment
