How To Stop Cheating In Test Grading

How To Stop Cheating In Test Grading Teachers have tried many tactics to stop their students from cheating. But, it was the teachers themselves who got caught cheating in 2011. They were erasing and changing their students answers on achievement tests to make themselves look better, according to an article in the New York Times. In recent years, the government has made the achievement or proficiency tests the cornerstone of its education debate. It uses these tests to measure students achievement, comparing them to students in foreign countries and past students. The government then blamed teachers for their students poor performance on these tests, and it even threatened many of them with their jobs if they could not improve their students scores. Many teachers simply could increase their students scores; so they took the easy way out and cheated. Some teachers gave their students answers to questions before the test; others showed students test questions, and some even erased and changed their students answers. Naturally, this was a huge scandal for education, and many administrators are now trying to make these tests more credible. The Department of Education created a panel in July to change the way achievement tests are graded. Some of its programs have already gone into effect, and others will require approval by states education policy boards. However, little has actually changed. All states must now administer the tests on the same day, and all educators who proctor or grade the exams must be certified to do so. Some states do not allow teachers to grade their own students exams; however, some still do. But, many educators and administrators feel that not enough is being done to ensure the credibility of these tests. They believe that every state should ban its teachers from grading their own students exams. Others believe that states should hire independent investigators to examine cheating scandals and help ensure it does not happen again. They want states to computer scan all answer sheets, looking for eraser marks because they believe that many teachers have gotten away with cheating However, education budgets are tight at every state right now, and implementing programs to ensure teachers from cheating seems unnecessary to many states.

What is a Lute, and How is it Different From the Guitar

What is a Lute, and How is it Different From the Guitar Shanika As a guitar player, I rarely had to deal with the issue of explaining what my instrument was to people I met. Even non-musicians are generally familiar with the guitar and the many forms and shapes it takes. When I made the transition to playing the lute, however, this changed significantly, due in no small part to the odd-looking case that I have to carry the instrument around in. People will often ask me, “What is a lute?” In truth, the history of the lute is a long one and I often simply explain that it’s like a guitar with more strings. If I have the time, though, I really do love to give a more complete answer. Read on to learn a brief overview of the history of the lute, and some comparisons between the lute and its more famous cousin, the guitar. The lute is a descendent of the oud, which was most likely brought to Western Europe by the Moors in the 9th century, when they occupied Spain. While the Spanish would seem a likely conduit for the instrument to enter the rest of Europe, they generally rejected the instrument, and the oud instead traveled with merchants through Sicily and up into Italy. The oud is a fretless melodic instrument, double-strung in courses, that is perfectly suited to the subtle tunings, systems and scales of the Middle East. In order to better integrate the instrument into Western European music, a few changes were made; adding frets was the first of these changes. Because Western European music was harmonically-driven and used precise tuning systems to harmonize multiple notes at the same time, the oud needed the addition of frets to comfortably play in tune with other musicians. This simple addition of frets marked the change from oud to lute. Despite the obvious harmonic implications that frets allow, the lute remained largely a melodic instrument until the beginning of the 16th century. Like oud players, the new European lute players continued to play the instrument with a plectrum or a bird quill. Through paintings and other iconographic sources, we have been able to reconstruct much of this early picking technique and determine that it is remarkably similar to modern mandolin and even electric guitar playing. The pinky of the plucking hand rests on the body of the instrument and acts as an anchor and a reference point for the rest of the hand. This allows for very fast and accurate diminutions. The fretting hand seems to have been very similar to modern technique. Depending on the size of the instrument, the thumb of the fretting hand could hang over the neck and even fret notes when needed, or if the instrument was too large, the thumb remained relaxed behind the neck. The end of the 15th century marked an amazing change for the lute, one that helped make it the most popular instrument for more than 200 years. A group of German lutenists discovered that by using the fingers to pluck instead of a plectrum, they could play entire polyphonic works. The hand position itself remained largely the same, but the instrument could now play solo material of remarkable complexity. The addition of a low sixth course (double string) also increased the gamut of the instrument, allowing for full bass lines. A few years later, the very first lute publications were printed by Ottaviano Petrucci. First came Francesco Spinacino in 1507, and then Joan Ambrosio Dalza in 1508. What becomes quickly apparent from these early publications is the high level of lute playing that is present so soon after the development of a polyphonic technique. The lute then exploded in the 16th century. Courts like those of Henry VIII, Francois I and the Pope in Rome hired lutenists as personal musicians and as means of cultural competition, pitting lute players against each other in contests that often impacted a rulers status amongst his peers. The highest-level lute players were paid in amounts comparable to modern NBA stars. Alberto da Ripa of Mantua, for example, was hired by the French court of Francois I, as the royal lutenist. In addition to earning the second-highest salary at court (of everyone, not just musicians!), he was given land and yearly stipends of food and alcohol. Intense competitions for these lucrative jobs produced musicians of unbelievable capability. The lute was easily the most dominant instrument of the 16th century, its regard only increased by the fact that it was linked (erroneously) to the Greek lyre of legend. The Florentine Cameratas influence on the arts in the 1570s and 80s helped propel a deep interest in reviving Greek culture, a culture that many considered the peak of human civilization. In fact, it was this invented connection to the legendary Greek instrument that may have allowed the lute to survive as long as it did. Despite its popularity during the 16th century, the lute began to lose ground in the early 17th century. The addition of more and more bass strings, up to 11 total courses (or 20 strings total, with two single strings), and the increased popularity and manufacturing of keyboard instruments, started to alienate the lute from the general population. The instrument was getting more difficult to play and more costly to maintain, and simpler instruments like the guitar were becoming more readily available. Thomas Mace, in his “Musicks Monument” (1676), tried to defend the lute and uphold it as the supreme instrument, but ultimately his argument showed that the lute was on a decline, and one from which it never quite recovered. Despite this decline, great players of the lute continued to produce amazing music and hold the highest positions at important courts. For example, the great German lutenist Sylvius Leopold Weiss (1687-1750) was the highest paid musician at the Dresden court and was reportedly so talented that another musician, jealous of his abilities, tried to bite his thumb off! The lute survived the 18th century, often playing continuo in orchestras, including Mozarts, and filling the second violin position in string quartets. Ultimately, the lute died out in the first decades of the nineteenth century. The beginning of the 20th century also marks the beginning of the lute revival. While early players and researchers like Diana Poulton did much to expand our knowledge of the lute, it wasnt until the virtuoso guitar player Julian Bream began playing the lute in concert that audiences and players started to become aware of the beauty and complexity of the instrument and its repertoire. The generation since Bream has elevated lute playing to very high levels. Players like Paul ODette, Robert Barto, Nigel North, and Hopkinson Smith tour the world and often have fanatical followings. The large body of music (60,000+ pieces) and its predisposition to added embellishment hopefully guarantee the lute a new life in the 21st century. Some students may be interested in how the lute differs from the modern classical guitar, an instrument that has come to share some of its repertoire. In terms of the actual instrument, even the largest lutes are significantly lighter in build than the average guitar. This lighter construction means that the lute is much more responsive, but produces less volume. The lutes double strings, or courses, tuned in octaves and unisons on the higher strings, produce a different timbre than the guitars thicker, single strings. The strings of lutes today are also generally either made of animal gut, nylgut (a synthetic gut), or nylon, while the classical guitar generally uses only nylon strings (wound and unwound). Depending on the type of the lute strings, the sound can be crisper and brighter than the modern guitar. The most obvious difference between the lute and the guitar is the pear-shaped body of the lute, which is produced by gluing ribs of wood together and then gluing the soundboard on top. This “tortoise shell” shape is descended from the oud, and some other instruments today, like the mandolin, have also retained this body shape. The lute can be a fickle, even difficult instrument, but when well-played, it produces some of the most beautiful and powerful music ever written. Perhaps one day it will regain its stature and stand beside the guitar as not only one of the most beautiful instruments, but also as one of the most popular.

However, our favourite artists aren’t the best resources for getting your voice right. Once you work out your voice type, you can sing more appropriate to your abilities. (Source: Free-Photos)This is all down to tessitura, which refers to your voice type and the range of notes you can hit. Once you’re outside of your range, you’ll struggle to regularly hit these notes.  You don’t need to repeatedly sing Mariah Carey songs.For women, there are four main tessiture:Contralto. The deepest range.Alto. Slightly higher but still a deep range.Mezzo-soprano. The deeper of the two high ranges.Soprano. The high range and the most common female voice.For men, there are also four main types of voice:Bass. The deepest male range.Baritone. The higher of the two deeper ranges and also the most common.Tenors. The lower of the higher chest voices.Countertenors. The highest range of male voices.Whether you’re a man or a woman, an amateur or a professional, you need to know what type of voice you have. Imagine getting ready for a concert with a list of songs that are outside of yo ur vocal range.  If you like a particular song but it isn’t in your tessitura, you’ll struggle to master it.Practise Singing According to Your Voice TypeOf course, practice makes perfect and regularly singing songs for your voice type will help you to improve. With a bit of practice, you’ll see that there are songs suited for different voice types and start to see the different registers.Here are popular singing lessons near me.

We can all sing, but we can’t all sing in tune and breathe correctly when we sing.

It’s pretty simple.What Type of Song Should You Choose if You Can’t Hit the Notes?“If everyone started off the day singing, just think how happy they'd be.” - Lauren MyracleEveryone can struggle to hit a note. Every voice can hit all t he notes within its range. You just need to be able to harmonise with any given note within your range. Before you start filling up stadiums, you need to work out how to get the most out of your voice. (Source: Free-Photos)You need to learn how to use your larynx, articulate your vowels and consonants correctly, and manage your stress. With the help of singing exercises and a teacher, you’ll soon start mastering your voice.From there, you’ll start asking about register and key when you start to become aware of your strengths and weaknesses. A singer with a higher tessitura can’t sing songs for a lower voice type.Your repertoire should reflect your voice type and include artists with the same voice type. Training is key to mastering your voice type.Imagine taking your stabilisers off for the first time. You need to go for it.Common Types of VoiceFor some, having a certain voice type will limit the songs they can sing. Very high or very low voices have a smaller repertoire to work from than the more common voice types. (Source: Pexels)Firstly, whether you’re a man or a woman will already dictate which songs you can and can’t sing due to the range of notes. Baritones and tenors (for men) and altos and mezzo-sopranos (for women) tend to have the advantage of a larger range when it comes to singing.We can’t promise that you’ll be singing operas but you’ll feel more comfortable with most songs. You don’t want to feel threatened by a song, after all.Similarly, the extreme ends of the spectrum will struggle with songs designed for the other end. A bass will struggle singing something for a tenor, for example. Whereas baritones and tenors should be more comfortable with it.  The idea is to learn what you’re capable of and don’t set unreachable goals.You also need to ensure that singing remains enjoyable. If it isn’t and your vocal cords are tired and you’re struggling with your breathi ng, you might need to change to a different song.In short, your voice is your instrument and you need to take care of it. Getting help from a voice coach or tutor is always a good idea. We can all sing as long as we respect our voices. While butchering a song is bad, butchering your vocal cords is even worse!The rest is up to you!Each voice range is different and just because you can't hit certain high notes, it doesn't mean that you can't become a great operatic singer. With a bit of vocal training and guidance from a voice teacher, you'll see which songs and pieces work well with certain vocal ranges.You can also learn more about registers from a singing coach or tutor. They can even show you artists with the same tessitura as you. Again, a tutor can help you work out the best repertoire.  If you'd like to learn more about singing, consider getting help from one of the talented tutors on Superprof. There are three main types of singing tutorial and voice coaching and each type has several advantages and disadvantages so what's right for one student may not be right for another.In face-to-face tutorials, there's just you and the tutor. This means that the tutor can focus on helping you to improve your voice and will put together a bespoke programme for you to follow. These are usually the most costly type of private tutorials since you're paying for all the tutor's time both in and out of class but they're also the most cost-effective.There are also online tutorials where the student is taught via webcam. With the tutor not having to travel to their lessons and being able to schedule more lessons per week, these tend to cost less per hour than face-to-face tutorials. Since the tutor isn't in the room there with you, these tutorials are better for academic subjects rather than vocational ones. If you both have a good microphone and a good internet connection, online tutorials are a great option for those wanting to learn to sing on a budget.Finally, there are also tutors offering group tutorials. If you and a group of friends are interested in learning how to sing, you could hire a tutor together and divide the cost of the tutor's time. Of course, you won't get as much individual attention from your singing coach as you would in the other types of tutorials but you will pay less per hour per student.No matter which type of singing coach you go for, they'll be able to help you work out your voice type, plan lessons that can help you improve your voice, and suggest songs and activities that work best with your tessitura.

Volunteer Day at Hidden Villa in Los Altos Hills

Volunteer Day at Hidden Villa in Los Altos Hills AJ Tutoring’s first volunteer days were great successes! Over two days, 25 tutors came out to work on the organic farm at Hidden Villa, an educational non-profit based on 1600 acres of land in Los Altos Hills. Hidden Villa’s mission is to inspire a just and sustainable future through its programs, land, and legacy. We were happy to volunteer our time to help that happen!One day’s crew was put to work in the CSA (community supported agriculture) plot to transplant crops for the growing season. In three hours, we were able to plant 2,000 onions, 800 heads of lettuce, and 80 fennel bulbs. Our transplanted spinach and tomatillos will provide nearly 500 pounds of food! We finished the hot afternoon by digging 500 “homes” for tomato plants that will soon be transplanted in the field.Our second day’s crew worked in the olive grove near the CSA lot. Hidden Villa’s half-acre olive grove produces hundreds of gallons of olive oil each year. We worked to cover the grove with mulch, which helps the soil around the trees retain moisture and nutrients. This group also took a farm tour, which included baby pigs, baby goats, and chicks.A big thank you goes out to the team at Hidden Villa for helping us coordinate these volunteer days!

U.S. Supreme Court Rules on Same-Sex Marriage

U.S. Supreme Court Rules on Same-Sex Marriage June 26, 2015 was a historic day in the United States, as the U.S. Supreme Court ruled 5-4 that the constitution guarantees the right to same-sex marriage.Before today, 36 of our 50 states allowed gay marriage, which covered 70 percent of all Americans.This is probably the most quoted part of todays  decision,  â€œNo union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family,” he wrote. “In forming a marital union, two people become something greater than once they were.  It would misunderstand these men and women to say they disrespect the idea of marriage.  Their plea is that they do respect it, respect it so deeply that they seek to find its fulfillment for themselves. Their hope is not to be condemned to live in loneliness, excluded from one of civilization’s oldest institutions. They ask for equal dignity in the eyes of the law. The Constitution grants them that right.”Same-sex marriage has long been a cont roversial topic in the United States,  even President Obama, who spoke today praising the decision, was quoted in 2004 as saying, marriage is something sanctified between a man and a woman.Below is a 2 minute segment from President Obamas speech today. Watch it and see if you can answer the questions below.Answer the questions in comments and we will respond.1. _ ___ __, theyve reaffirmed that all Americans are entitled to the equal protection of the law.2.  The statement above addresses the constitutional reasons for this decision. What does it mean?3. Why do you think he called our current system a patchwork system?4. What uncertainty does this remove for same-sex couples?5. How does Obama think this decision will affect marriage?6.  Do you think this change in U.S. law will have an effect in other countries?
