Harmful Myths About The Learning Process

Guest Post by Kaitlyn Cole

Learning happens. Everyone picks up information at their own individual pace, yet myths painting different demographics and techniques with a broad brush still creep their way into classrooms and the public consciousness alike. Feeding into them, however, proves exceptionally problematic to child and adult students hoping to eke through life with the skills they need to accomplish their goals. Parents, administrators, faculty, and even the students themselves might want to start chipping away at the following misconceptions first.

Females are inherently worse at math than males: Science knows full well that gender holds absolutely no influence over math skills, yet overarching perceptions still assert that the ladies aren’t nearly as adroit in its tenets as men. University of Wisconsin-Madison’s Janet Hyde spent nearly two decades studying the phenomenon, proving the lack of correlation with more than a million participants. The danger here is quite obvious. Hammering alleged biological inadequacies into young girls’ heads will serve as a self-fulfilling prophecy compromising their grades and future careers alike.

People with learning disabilities are of below-average intelligence: As University of Hawaii points out, learning disabilities only appear in individuals (of any age) of average to above-average intelligence; anything involving mental aptitude falls under a different definition entirely. Learning-disabled students actually hold a gifted rate around 33%, completely defying the unfortunate prevailing opinion. Once again, parents, teachers, administrators, and peers who adhere to this mindset only pile on the social anxiety, rendering it more difficult for them to succeed — even with all the tools necessary to help them get ahead. If they grow up thinking they’re somehow inferior, they might never strive toward being the best they can in the classroom, office, and beyond.

Children from lower socioeconomic backgrounds are inherently poor achievers with little intelligence: Because up to 70% of a person’s behavior is determined by nurture rather than nature, it’s irresponsible — not to mention discriminatory — to act as if kids, teens, and adults from lower socioeconomic brackets genetically possess lower intelligence. Environmental factors play the most prominent role in the lower test scores educators, politicians, and parents use to illustrate impoverished kids’ alleged inadequacy. Poor performers may bring home report cards reflecting bad nutrition, exhaustion and stress from work and/or family demands, or other stimuli. Acting as if their very real problems only indicate stupidity creates a terrible, unjust cycle of suppression and denial of wonderful opportunities.

Lecture learning is always the way to go: Yes, lectures most assuredly hold a place in education — nobody’s asking for schools to entirely dismantle the concept and stuff it into storage. But they aren’t the be-all, end-all techniques for getting students learning, either. Experts find the passive element disconcerting, but not nearly as much as how exclusive adherence to lecture-based learning takes such a “one-size-fits-all” stance. Different people process information in different ways, and the most effective classrooms blend together strategies and activities meant to engage everyone.

Rote learning is the devil/Rote learning will save us all: Honestly, both demonizing and evangelizing rote learning cause roughly equal amounts of damage. Balance, as in most areas of life, proves key when navigating this volatile education controversy. Some students and subjects greatly benefit from the repetitive memorization approach, so calling for its demise isn’t responsible. But touting it as the greatest learning technique since, well, ever is equally detrimental. The trick is in finding rote learning’s proper place and relationships with other strategies.

Standardized testing is an accurate measure of a school’s abilities: No Child Left Behind dishes out funding based on how schools perform on standardized testing, with higher scores meaning more money. The problem here is that support typically ends up going toward institutions in wealthier areas. Experienced teachers tend to gravitate toward these, and students enjoy far more access to learning enhancement technologies in the classroom and at home. Because intelligence and socioeconomic status do not inherently impact one another, all the legislation does is hand out rewards based on what’s available in the classroom. This creates a saddening cycle where economically deprived students do not receive equal opportunities before, during, and after their education wraps up — thereby perpetuating the nauseating myths that they don’t deserve anything because they’re just not smart enough.

Race holds influence over intelligence: Stephen Jay Gould may have dismantled the notion that race (and therefore cranial size) determines one’s mental aptitude in 1981′s The Mismeasure of Man, but vestiges of the once-mainstream mindset still cling — especially when one factors in family income. DNA, of course, undeniably holds sway, but not the little bits and pieces dictating skin color and facial structure. Those are too busy with their own jobs to bother with what’s going on in the ol’ grey matter. There’s also the little fact that minority and majority students both perform poorly when racial bias creeps into the classroom as a result of self-fulfilling prophecies. Merely treating classroom denizens as the equals they are nurtures overall improved aptitude.

Adults and kids can learn languages using the same approaches: Many second-language teachers — despite harboring good intentions — accidentally make coursework harder for their adult students by incorporating techniques used to teach kiddos a first. Children and adults obviously possess different learning needs, and primary and secondary tongues each require their own unique sets of strategies for effective absorption. To approach every situation armed with the exact same syllabus makes it much, much harder for adults needing to incorporate themselves in a foreign culture. Immersion, for example, is discouraged since most people over the age of 18 lack the time to fully submerge themselves in nothing but a new language.

Average- to low-performing students do better when incorporated into gifted classrooms: Students do tend to enjoy better grades and soak up lessons more effectively in groups, but more intelligent participants aren’t quite the inspiring role models educational professionals think, intentionally, anyway. Actually, they perform more adroitly when grouped with others of similar aptitude rather than peers with average to low intelligence. The National Association for Gifted Children notes how “outperforming” kids and teens usually leave the rest feeling inadequate, which might very well lead to bullying, which knocks the higher performers down because of depression and isolation.

Special education programs are only for severe cases and require special classrooms: Parents are far more likely to buy into this horrid myth than professional educators, which means denying their children access to resources needed for a well-rounded academic career. Because public schools accept federal funding to provide everything special needs students require, legally, districts must accommodate all the situations they encounter. It might even mean no more than an hour outside of mainstream classrooms a day, or the simple incorporation of lo-fi technology. Special needs come in all severity levels, so if a doctor says steps need taking, moms and dads better heed their instructions.

Doing your best is … well … best: Whether teaching adults or kids, more clear-cut goals foster more solid results; most tend to find well-meaning sentiments like, “Do your best!” too broad and ambiguous. Ratchet up the difficulty levels when wanting to issue forth challenges, and make sure to help students outline clear goals for themselves. This strategy will help increase lesson absorption while preserving the same positive confidence-building present in the more common vagaries.

Urbanization Debate:Is sub-Saharan Africa becoming urbanized?

Dear Readers

While Researching found this very interesting debate . reproducing it with relevant links and credits.See , Think and give inputs.

Research on urban growth has traditionally focused on the Western metropolis, which was shaped by the massive industrialization, modernization, and migration patterns of the nineteenth and twentieth centuries.  In recent years, scholars have started to examine the growth patterns of cities in other regions, such as sub-Saharan Africa, and to question the universality of the Western model of urban development. While earlier data had led many scholars to concludethat cities in that region are growing at an unprecedented rate, new research has challenged the notion that Africa is fast becoming an urban continent.

Rapid growth

In Planet of Slums, urban theorist Mike Davis reported that according to Organization for Economic Co-Operation and Development (OECD) estimates, by 2020 the Gulf of Guinea will be home to three hundred cities, each with a population greater than 100,000 people. Historians Francesca Locatelli and Paul Nugent attributed the growth of sub-Saharan urban areas to the migration of rural residents to cities as well as to higher birth rates in urban areas. Using data originally contained in the 2002 UN publication The World Urbanization Prospects, together with data provided by the World Bank, demographer Barney Cohen projected that fifty-three percent of the sub-Saharan African population may live in urban areas by 2030, a dramatic increase from the first decade of the twenty-first century, when only thirty-eight percent lived in cities.

Slow development

Geographer Deborah Potts questioned these urban growth rates after analyzing UN-HABITAT data on cities in Malawi. With these data, Potts found just a one percent increase in urbanization between 1998 and 2010. Potts suggested that predictions of rapid growth made by other scholars did not adequately reflect the fact that in the 1970s, after several decades of rapid growth, the region entered a period of significant economic hardship that continues to the present day. As a result, rural residents have had little incentive to relocate to larger cities for work.

Resource allocation

As Potts argued, revisiting previous population estimates and growth models is necessary for the accurate allocation of financial and material resources. Equating population growth with urbanization can have negative consequences, she cautions, since the needs created by slow urban growth through increased birth rates are different from the results of projected rapid growth through migration. Understanding the exact model of urban growth at play in the sub-Saharan region is crucial, Potts argues, for politicians and development agencies that may adapt public policy in ways that would further encourage migration to cities.

Dark Energy triggered expansion of Universe six billion years ago:A 3D Map by Astronomers

What is Dark Energy?

More is unknown than is known. We know how much dark energy there is because we know how it affects the Universe’s expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 70% of the Universe is dark energy. Dark matter makes up about 25%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the Universe. Come to think of it, maybe it shouldn’t be called “normal” matter at all, since it is such a small fraction of the Universe.

 Researchers have come up with a 3D map of the sky, which facilitates scientists to look into the time six billion years ago when dark energy became a dominant influence on the Universe’s expansion.

Universe Dark Energy-1 Expanding Universe This diagram reveals changes in the rate of expansion since the universe's birth 15 billion years ago. The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about 7.5 billion years ago, when objects in the universe began flying apart as a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. NASA/STSci/Ann Feild

Using the new data, astronomers have been able to measure the exact distance to over a quarter of a million galaxies to gain new understanding of the key period in cosmic history. The discovery that everything in the cosmos is moving apart at a faster and faster rate was one of the major breakthroughs of the 20th Century, and the BOSS survey is a step to examine this phenomenon.The quality of the BOSS map is phenomenal and is a  big step forward on all previous such surveys.
It provides details on the position of galaxies out to some six billion light-years from Earth and gives those measurements to within 1.7 percent of their expected true value.
BOSS uses two techniques to understand the Universe’s acceleration, the first one of them is baryon acoustic oscillations.

These oscillations  are pressure-driven waves that passed through the very early Universe and which were imprinted on the distribution of matter once conditions had cooled below a certain point.
The other technique involves “redshift space distortions”. These describe the component in the velocity of galaxies that stems from the growth of structure in the Universe. The team can see if neighbouring galaxies are clustering in the way that would be expected from the action of gravity.
The BOSS project, which acquires all its data using the 2.5m Sloan telescope at Apache Point Observatory in New Mexico, is only a third complete and will continue to map the 3D positions of galaxies.

Lets see what the future holds for us.

Sometime around 1968, in the south of France, I remember looking up a hill as someone pointed out to me the remains of a Roman aqueduct, still there after 2,000 years – a high wall with arched openings and a stone channel on the top where water used to run.  The Roman system of aqueducts carried water for irrigation and drinking across much of Europe, just as the Roman roads created a transportation web.  Many modern expressways in Europe follow these same ancient paved highways, built by the Roman legionnaires.

What is not so well known is that the Romans did not themselves invent either aqueducts or the system of paved roads.  It was actually the genius of the Etruscans that developed these and a number of other technical wonders.  Etruscans had a high degree of technical knowledge.  They developed the intricacies of water and sewage management, plumbing, irrigation, and…
