The 7 Steps to Language Learning



Just as an infant must first drink milk, before eating solids, prior to the brain processing complex language abstractions, the networks for basic language foundations must be first laid down. All higher circuits build upon whatever the lower brain circuits have developed earlier, but those circuits must be pre-existing or there will be little on which to build. Infants and toddlers learn language in this recommended sequence of developmental events

1. Hear songs, children’s lullabies, and music, which teach infants the distinct phonemic elements – the building blocks – of the local language. To build a foundation in the language, an infant must hear the sounds that are most useful to their language. Songs for children, characteristically stress the high frequency/high utility sounds and grammatical patterns found in the local/regional language. (The sense of hearing goes “on-line” at 7 months in utero, when fetues begin eavesdropping on the language of the locality into which they will soon be born.)

2. Sing those songs themselves and learn how to produce the sounds via mimicry -- watching others. With their budding "mirror neurons" active, infants fixate on the lips and mouth of a singer (or speaker) and mentally “rehearse” how he/she would produce those same sounds well before the infant is capable of physically replicating the songs with voice. They begin to “babble,” or practice the language.

3. Listen to, repeat, and then recite children’s poetry where they begin to notice the similarities in sounds (words/word sounds that rhyme) by practicing the primary phonetic elements.

4. Listen to short stories emphasizing sentence structure, grammar, syntax, and the predictable nature of language (subject-verb agreement, the word order for adjectives and the nouns they describe, etc.) to learn language structure.

5. Repeat/re-tell stories in their own words making personal sense of words, content, and context. Oral language develops our “phonological loop,” where a child begins to listen to his own voice while speaking, and later, while reading. Words are used to think, not just to read, as we have learned. A limited vocabulary is a crucial factor underlying failure in school (particularly for disadvantaged students.) The “context processor” in the brain constructs an on-line, coherent interpretation of what is being heard. If he is fortunate enough to have a lengthy personal background where others have read to him, his phonological loop will more readily integrate those past language experiences into future language production. For that child, learning to read is a skill that develops considerably faster than for others. Children don’t learn exclusive from listening to stories. They benefit more from the give-and-take in discourse about the stories. That is where they learn how to use language.

6. Draw pictures of story events, objects, and characters, where children learn to create mental pictures in their “mind’s eye.” Nouns are typically more readily activated in the mind than words describing intangible concepts. Drawing will bring the abstract closer to mind. Drawing does for the brain during the day what dreaming does for the brain at night. Pictorial representations and symbols (art) have been part of the human experience for far longer than the printed word.

7. Begin reading and writing with symbolic language. Now, the child is ready. For boys, this may take 6-7 years.

Nobel Prizes and Synapses


What do Nobel prizes and synapses have in common?

In order for us to move, feel and think, neurons in our brain relay messages to one another. When neurons "chat" among themselves, their means of communication relies on both electricity and chemistry.

Once incoming stimuli of a specific type reach a threshold point, a 270 mph electrical impulse “fires” and is transmitted down the axon of a neuron, the elongated portion of the nerve cell.

The chemical component of this informational exchange occurs by means of over 70 neurotransmitters (brain chemicals) and neuromodulators. Once the electrical impulse reaches the end of the axon, a tiny pocket of chemicals bursts releasing neurotransmitters (the “chemical couriers”), which travel across the synapse, a microscopic gap separating two theoretically “connected” neurons. The “apse” in synapse means binding, and “syn” meaning together.

Synapses in reality are contiguous rather than continuous contact points between the message-sending or pre-synaptic neuron and the post-synaptic or message-receiving neuron.

As neurotransmitters cross the synaptic gap they lock into receptor sites on the post-synaptic neuron (the next neuron on a neural pathway) and convey their chemical message only if their molecular properties fit the precise configuration of the receptor sites on the post-synaptic neuron. Over one quadrillion (1,000 trillion) synaptic connections can be established inside the human brain. Each neuron can make 15,000 to 200,000 connections with other brain cells.

Creating new synapses and delivering the appropriate types and quantities of neurotransmitters in these chemical communications, is the foundation of the event we generically call learning.

Although synaptic transmission is just one aspect of how the brain functions, three Nobel prizes have been awarded (to Arvid Carlsson, Paul Greengard, and Eric Kandel) for their research on this single portion of our complex brain transactions.

Linking Education and Economic Progress

While education is enjoying a global resurgence, it continues to be the target of conservative politicians in the United States. The World Bank places a premium on education, and more specifically, the education of young girls in developing Third World countries.

Today, loans to poor nations are granted with this single factor used as an important criterion in the loan-granting process. Educated women typically give birth to fewer children (an average of two rather than eight). The two children hailing from the smaller households will typically receive an education, because of two primary factors:

(1) formal education (instead of daily survival) in smaller families rises to the level of a high "family priority," when monthly income leaves funds available for discretionary spending, and
(2) more family resources can be invested in schooling rather than in basic needs of food, clothing, etc., for a large number of family members, who are not making even modest contributions to the family income. The ultimate fiscal drain on limited family resources often spells foreclosure on financially out-of-reach educational opportunities.

National instability and political oppression, coincidentally, often accompany high levels of poverty and low levels of education. Countries with a substantive middle-class population typically enjoy greater political stability, which allows them to make good on their World Bank loans.

The current attack on public employees in general, and public education in particular can be disastrously short-sighted recognizing the high correlation that we all acknowledge between a quality "education for all" and global economic standing.

There are no "internal winners" in the senseless assaults on public education. In both the long-term and the short-term, our entire nation will suffer when we don't support public education and maximize learning for every child who walks into our doors.

The First Ph.D. in Psychology

The first Ph.D. ever awarded with the term “Psychology” in its title was granted at Harvard University in 1878.

Barely fourteen years later, the American Psychological Association was the center of this fledgling discipline, which was quite “undisciplined” since it was not driven by any precise methodological or scientific focus. One hundred years later, Pres. George Bush declared the 1990s “The Decade of the Brain.”

During the intervening decades, our understanding of the human brain mushroomed as our knowledge base catapulted from mere conjecture, guesswork, and speculation to a domain grounded in biology, medicine, and science.

Parenting and education were two areas of the modern human experience that seemed almost impervious to the incredible findings in neuroscience until recently. Remarkably, no two arenas are better positioned to put this research into daily practice. To our collective good fortune, today we see educators, parents and neuroscientists seeking to understand the aspects of behavior, learning and memory.

The Science of Learning


We receive questions frequently about student learning. One question that has been asked several times and in numerous different ways is, "Can you recommend a short list of priorities for learning?" Those items should always include the following:


• Hands-on, minds-on, heart’s-in learning experiences (experiential learning)

• Relevance to the student’s personal life whenever possible (it is relevance that makes "rigor" achievable)

• Active learning, which is how the brain learns best and remembers most effectively (engagement)

• Student-centered learning, which increases the probability of student achievement

• Technology, manipulatives, and simulations followed by student writings on those experiences

• Metacognitive learning where students analyze, reflect on, and discuss their thinking processes

• Differentiated learning, since students learn at different rates and by different means

• Diverse learning styles using multiple intelligences to address the different ways of knowing and different ways of learning

• Build from the concrete experience to the pictorial/representational to the abstract/symbolic

• Provide a physically and emotionally safe learning environment• Build upon past learning and prior knowledge (schemas)

• Learners must apply their learning in order to establish long-lasting neural connections

• Capitalize on a child’s interests and strengths for motivation (requiring “Emotional Intelligence”), while helping a child learn how to “manage” his/her “emerging talents” (a.k.a. "weaknesses") competencies, and skills.

The Achievement Gap and Testing: Understanding standardized Testing Below Its Deceptive Surface (Part III)

When two youngsters are administered the same timed-test and each receives a score of 6/10 correct, we assume that they are working at the same achievement level. Student “A” may have responded with six correct answers after completing only six of the 10 items. Student "B" may respond knowledgeably and correctly to only three test items. He guesses at the remaining seven questions of which four are coded “incorrect” and only three are correct. If Student “A” had more time, he may have received a perfect score of 10 out of 10, because he actually knew the concept well, while Student B's score might continue to fluctuate solely based on the mathematical probabilities associated with guessing at four random multiple-choice items.

Don't our children also deserve to be measured by more than high-stakes test? When making decisions that have a long-term impact on our lives (college attendance, a home purchase, or which car should we buy), numerous factors are frequently entertained and multiple measures are used before we arrive at a final conclusion.

The American Educational Research Association, the American Psychological Association and the National Council on Measurement in Education advocate using multiple resources for student assessment. There should be multiple types of information used from assessments, multiple formats of assessment, more reliance on formal and informal testing occasions where proficiency can be demonstrated, and multiple opportunities for students to “show what they know" in a risk-free, stress-free environment where the actual demonstration of knowledge is more important than what the clock says.

The Achievement Gap and Testing: Understanding standardized Testing Below Its Deceptive Surface (Part II)

Pay scales for classroom practitioners are characteristically governed by (1) the degrees earned, and (2) the length and quality of job experiences, which is comparable to most other professional occupations.

However, a suburban high school, where 80 highly qualified and experienced teachers are paid an average of $1,000 more per teacher, per month than their cross-town colleagues in the inner-city, is investing in excess of $1 million dollars more per year in salaries and benefits for those educators. Yes, that substantial difference in investment certainly should yield an expected return annually.

While formal assessment and standardized testing can serve a worthwhile mission, all tests are not necessarily accurate indicators of knowledge attainment, skills acquisition, scholarly competence, or "school quality." Yet, we have faith in the erroneous equation...

more pressure on teachers = more learning = better test scores.

When the multifaceted processes of teaching and learning can be reduced to “a bubble” on a multiple-choice test item, we have significantly degraded cognitive development and the intrinsic importance of intellectual exploration. Innovative thinking has never been stimulated by standardized testing.

Even more important, many of the most beneficial human traits, dispositions, and attributes (ingenuity, persistence, compassion, creativity, dependability, controlling impulsivity, adaptability, flexibility in thinking, integrity, originality, self-sufficiency, etc.) that have sponsored the greatest advances in human development, go untested and completely ignored by standardized tests.

These characteristics typically determine the success in life and the quality of one's life, although they are most unwelcome on standardized tests.

Albert Einstein once said, "Everything that can be counted does not necessarily count; everything that counts cannot necessarily be counted” or calibrated on a standardized test. As adults, our "character" is informally assessed daily, where it counts -- our professions and our entire lives.

What do you think?

The Achievement Gap and Testing: Understanding standardized Testing Below Its Deceptive Surface (Part III) follows tomorrow.
