Win Friends & Influence People Through Music — Is It Possible?

March 28th, 2008
Duane Shinn asked:


The idea that studying music improves the social development of a child is not a new one, but at last there is incontrovertible evidence from a study conducted out of the University of Toronto.

The study, published in the August issue of Psychological Science was led by Dr. E. Glenn Schellenberg, and examined the effect of extra-curricular activities on the intellectual and social development of six-year-old children. A group of 144 children were recruited through an ad in a local newspaper and assigned randomly to one of four activities: piano lessons, voice lessons, drama lessons, or no lessons.

Two types of music lessons were offered in order to be able to generalize the results, while the groups receiving drama lessons or no lessons were considered control groups in order to test the effect of music lessons over other art lessons requiring similar skill sets and nothing at all. The activities were provided for one year.

The participating children were given IQ tests before and after the lessons. The results of this study revealed that increases in IQ from pre- to post-test were larger in the music groups than in the two others. Generally these increases occurred across IQ subtests, index scores, and academic achievement.

While music teachers across the country greeted the new research enthusiastically, in fact, many other studies have previously shown a correlation between music study and academic achievement.

In 1997, well known music researchers Frances Rauscher, Gordon Shaw and their team at the University of California (Irvine) reported that music training is far superior to computer instruction in dramatically enhancing children’s abstract reasoning skills, the skills necessary for learning math and science. A group led by the same two scientists had earlier showed that after eight months of piano lessons, preschoolers showed a 46 percent boost in their spatial reasoning IQ.

The March 1999 issue of Neurological Research published a report by another group of researchers, also at the University of California (Irvine), who found that second-grade students given four months of piano keyboard training, as well as time playing newly designed computer software, scored 27% higher on proportional math and fractions tests than other children.

Students with coursework and experience in music performance and music appreciation scored higher on the SAT, according to a Profile of Program Test Takers released by the Princeton, NJ, College Entrance Examination Board in 2001. This report stated that students in music performance scored 57 points higher on the verbal and 41 points higher on the math, and students in music appreciation scored 63 points higher on verbal and 44 points higher on the math, than did students with no arts participation.

Another part of this same study shows that longer music study means higher SAT scores. For example, students participating in the arts for two years averaged 29 points higher on the verbal portion and 18 points higher on the math portion of the SAT than students with no coursework or experience in the arts. Students with four or more years in the arts scored 57 points higher and 39 points higher on the verbal and math portions respectively than students with no arts coursework.

Another study also found support for a relationship between math achievement and participation in instrumental music instruction. The researchers found that students who participated in instrumental music instruction in high school took on the average 2.9 more advanced math courses then did students who did not participate.

In fact, various studies over the last 10 years suggest teaching kids music can heighten their aptitude for math, reading, and engineering. (One explanation for improved ability in mathematics is that music theory is based on mathematical truths. Rhythms are divided into fractions – half notes, quarter notes and eighth notes. Scales have eight tones, and the steps between them follow an equation.)

A McGill University study in 1998 found that pattern recognition and mental representation scores improved significantly for students given piano instruction over a three-year period. The researchers also found that self-esteem and musical skills measures improved for the students given piano instruction.

And data from the National Education Longitudinal Study of 1988 revealed music participants received more academic honors and awards than non-music students, and that the percentage of music participants receiving As, As/Bs, and Bs was higher than the percentage of non- participants receiving those grades.

In 1994, a report entitled “The Case For Music Study In Schools” was printed in Phi Delta Kappan, the professional print journal for education. It included details of research conducted by physician and biologist Lewis Thomas, who studied the undergraduate majors of medical school applicants. Thomas found that 66 percent of music majors who applied to medical school were admitted, the highest percentage of any group.

The same report asserted that the very best engineers and technical designers in the Silicon Valley industry were, almost without exception, practicing musicians.

The world’s top academic countries also place a high value on music education. In a study of the ability of fourteen year-old science students in seventeen countries, the top three countries were Hungary, the Netherlands, and Japan. All three include music throughout the curriculum from kindergarten through high school.

St. Augustine Bronx elementary school, about to fail in 1984, implemented an intensive music program, and today 90 percent of the school’s students are reading at or above grade level. And a ten-year study at UCLA tracked more than 25,000 students, and showed that music making improves test scores. Regardless of socio-economic background, music-making students get higher marks in standardized tests than those who had no music involvement. The test scores studied were not only standardized tests, such as the SAT, but also in reading proficiency exams.

Music training helps under-achievers as well, according to research published in Nature magazine in May 1996. In Rhode Island, researchers studied eight public school first grade classes. Half of the classes became “test arts” groups, receiving ongoing music and visual arts training. In kindergarten, this group had lagged behind in scholastic performance. After seven months, the students were given a standardized test. The “test arts” group had caught up to their fellow students in reading and surpassed their classmates in math by 22 percent. In the second year of the project, the arts students widened this margin even further. Students were also evaluated on attitude and behavior. Classroom teachers noted improvement in these areas also.

In 2005, it appears the pace of scientific research into music making has never been greater. The most recent evidence from the University of Toronto confirms what many other researchers have already detected – that music boosts brainpower, academic achievement,socialization skills, and emotional health.

It’s logical, when you think about it. People who learn to play an instruments are in groups—bands, choirs, orchestras, combos, worship teams, etc. And working and making music with others is bound to help relateabilty with people and foster close bonds with fellow musicians.

So it appears that learning to play music, whether guitar, piano, or some other instrument, actually does contribute to your ability to “win friends and influence people.”

Is High Iq Equal to High Math Marks

Frank Ho asked:


Is High IQ Equal to High Math Marks

Frank Ho, Amanda Yang

Canada certified math teacher and founder of Ho Math and Chess

www.mathandchess.com

After testing a few students I seem to get the conclusion that a above average IQ scores do not necessarily translate to high math marks. The categories tested including logic, memory, sequence etc, these are strong factors could influence children’s math ability. Why these above average to high IQ students do not score high math marks? Some of these students studied hard and yet could not do well in their math tests, why? I started to study how they tried to solve problems and what difficulties they encountered when trying to solve math problems and found out that there are still a few factors which affect their math ability but the general IQ test do not seem to find out these weakness areas which are not related to their math ability.



They do not know math short cut or tips. General IQ test do not test these areas.

The can not work backwards or do reverse thinking. Often the IQ test does not require formulas and even high IQ students have difficulties in applying equations.

They can not put all conditions or information together and then solve problems. For example, the IQ test will test one’s memory, logic or pattern in separate pages but often the math problems require children to apply all on one problem and IQ test questions do not seem to have these kind of problems to test them all skills on one problem.

IQ test does not teach children on something in advance and then test on their understanding so there is no cause and result effect of teaching involved. Math learning involves teaching (conceptual learning) and the later stage of practice, so if the children are not interested in carrying out the completion the fluency of procedural learning then their math marks will not be high when tested.

Are children interested in study? If they are simply trying hard because their parents want them then the results will be different from those who are inherently interested in doing research.

Are the skills shown in high scores of IQ test transferable to math test? This answer may not be a definitely yes.

Often Math problems require learned knowledge to solve them and these learned knowledge require practice so even though some children have got high IQ scores but may not have high math scores since they did not put in efforts to do enough practice to master the skills. For example, I observed that some high schools do not remember how to use formula to expand (x – y)^2 or know how to factor x^2 – y^2 and these have very little to do with real life experience. The reason is they have not done enough practice so they will not do well when these skills are required to solve some algebraic problems even though they may have high IQ test scores.

Some high IQ children do not care if what has been taught is clearly understood or not, no research spirit to find it out or ask someone to clarify the confusing points.

Bad study habits or even bad living habits so they affect their learning ability that they can not organize or analyze their thoughts. For example, if some presentation points were not understood by high IQ children and if these children do not even bother to take notes or earmark on those points and review them then how can they get high marks if those points were tested later?

The Role of Iq in Measuring Intelligence

March 12th, 2008
Andrew asked:


The qualifying genius level is different for every intelligence quotient test, and they can not give a clear answer to the question what genius is. For instance, the qualifying genius level on the Cattell IIIB makes 148, putting in this way the genius into the eighty third percentile rank. On the Stanford-Binet a genius occupies the eighty sixth percentile rank, with a qualifying genius level – 132. So, we can see that the answers of these tests are discrepant, they can not be compared and consequently, they are not objective. Even in case if the intelligence tests were comparable and objective, the high intelligence quotient does not mean that a person is a genius, the same concerns the low IQ, it doesn’t mean that a person with low IQ mentally challenged. Though the IQ of Andre Massena, one of the most talented commanders of Napoleon’s army, was 103, Napoleon said that Massena was the greatest person of his military Empire. The IQ tests serve to define the functional level of intelligence; it is connected with the fact that they are not able to determine the conceptual capacity of the intellect.

This brings us to a striking realization. If intelligence quotient which is the most precise thing to measuring intelligence level, is actually not a reliable measure of mental power, then we have no way to measure the intelligence without having a doubt concerning the fact that somebody is a genius. Such factors as audience and altruism are not enough to give a concrete characteristic of a genius. These two features are more likely to indicate something else, something that is characteristic of every person: desire. Genius is the accomplishment of these desires, the desires to be admired, adored etc. If taking objectively, genius does not exist, because people are not born genius, they may become genius.

The Effects of Genetic and Environmental Factors on Iq

March 3rd, 2008
Alexander Roulinski asked:


For the last 140 years, scholars have been preoccupied with identifying the exact factors that influence one’s IQ. The numerous studies on the subject have led most scientists nowadays to the belief that one’s IQ is determined by a variety of both genetic and environmental factors, although there is contention about the exact weight of each.

The majority of studies on intelligence have shown that environmental factors account for about 25% of the differences in people’s IQ scores. The factors that have been of greatest interest to scholars include prenatal development, nutrition, birth order, home and family environment, and the effects of schooling.

Prenatal development

Scientists have discovered many factors during a woman’s pregnancy that could affect a child’s cognitive development. Among them are:

… the mother’s health, including her nutrition and smoking and drinking habits during pregnancy, her age and the number of previous pregnancies, the interval since her last pregnancy, blood type and Rh incompatibility of mother and fetus, her history of X-ray exposure, and her red blood cell count, to list a few (Jensen; 169).

Nutrition

Despite researchers’ initial belief that nutrition played a significant role in a child’s cognitive development, so far, there has been no substantial evidence that differences in nutritional habits have a noticeable effect on IQ, unless a child has suffered severe and prolonged malnutrition in early childhood.

Birth order

Surprisingly, statistical data shows that birth order can somewhat affect IQ:

Each successive child born into a family has, on average, a slightly lower IQ, by about .7 IQ point, than the previous born child… A parallel effect is found on scholastic achievement as well (Jensen; 171).

Home and family environment

One of the factors that many people attribute an important role to in mental development and differences in IQ is home and family environment. The latter encompasses variables such as:

… neighborhood, the number of rooms in the home … the number of magazines and books, the parents’ educational and occupational level, family income, whether private music lessons and dance lessons are given to child, membership in established organizations, and travel experiences (Jensen; 173).

Schooling

In addition, scholars have also examined the effects of schooling on a child’s IQ. They have discovered that differences in school quality have no detectable influence on a child’s intelligence test scores. What proves to be of greater significance is regular school attendance, especially in elementary school.

Genetic factors

Besides environmental influences, most scientists today believe that genes also play a part in determining one’s IQ. However, there is currently an intense debate whether genetic or environmental factors are the deciding influence.

To sum up, science has come a long way in understanding the different factors that shape one’s intelligence. However, there are still contentious issues that need to be clarified.

Iq Tests: are You Really Clever?

March 2nd, 2008
Elio Galluzzi asked:


Have you ever been into an IQ test?

 

Some time ago I was involved in a test of this kind and as soon as I reached the end I got a score representative of my “intelligence”. It was one of those online tests taking about half an hour of your time, where you surf between anagrams, mathematical series and visual pattern recognition. An average person should score around 100 and when you totalize over 120 you are said to belong to an elite of “superior” or “gifted” individuals.

 

As a consequence, when you score high you feel great, a genius, but on the other side of the badge a low score can make you question your brain power and you will end up to claim that this kind of tests are mere trivial mind games and nothing more, taking your self esteem back.

 

Following the above considerations, what I wonder is whether these tests are a really good assessment of intelligence or not. IQ is a “psychometric” test, measuring mental ability, but define intelligence is far from being simple. Some psychologists believe that intelligence can somewhat be genetically inherited, while others sustain the thesis that the development of the mind might be the result of social background. The way to determine the real validity of an IQ test to assess general intelligence is debatable. Many see those tests as an appraisal of problem solving skills rather than a metric to measure intelligence. Besides, they are not accurate tests of creativity and other elements important to assess and individual’s effective intellect power.

 

Anyway IQ tests are popular and because of their supposed ability to measure intelligence they have been widely used by many companies and institutions over the years. There are many associations where the entry requirement is a particular high IQ score, like the famous Mensa, gathering something like 3% of the civilized population. Other groups which flourished and spread on the internet are so elitarian that will accept only members with an IQ of 140 or higher –Albert Einstein was supposed to score around 160.

 

In conclusion, when you take an IQ test don’t be too excited or depressed by your score, your genius can be misunderstood.
