Procesul de "predare-învăţare"

The Learning Process vs. Intelligence

Procesul de instruire-învăţare

MOTTO: "An intelligence is the ability to solve problems or to create products, that are valued within one or more cultural settings". (Gardner 2003)


Este corect utilizat termenul de "predare" in cazul activitatii unui profesor (cadru didactic)? Nu, dupa parerea mea, deoarece este vorba de CUNOASTERE si INVATARE. Dupa cum vom observa, cunoasterea depinde atat de individ, cat si de comunitate (societate), in timp ce invatarea depinde doar de individ. Mai degraba se poate folosi expresia "instruire-învăţare"

CUNOASTEREA (un tezaur al omenirii): spatiu virtual si fizic de inventii, cunostinte, studii, analize, experimente si inventii stocate/pastrate sub diverse forme: carti, reviste, suporturi magnetice si optice, biblioteci digitale, etc. actualizate prin diverse cuceriri stiintifice, culturale etc.

INVATAREA (procesul/drumul catre cunoastere si fericire): omul este sortit sa inceapa -inca de la primele secunde de cand vine pe lume, un lung proces de cautare, de adaptare, de experimente, de bucurie, de fericire, de tristete, de dureri ... de impliniri, de remuscari ... de viata. Drama lui este ca toate acestea sunt influentate de evolutia cunoasterii proprii, ce inseamna de fapt INVATARE. ["Learning is evolution of knowledge over time" Roger E. Bohn, Ref.: ]

KNOWLEDGE: a treasure of humankind
LEARNING: the process / path to knowledge and happiness

"O pledoarie pentru schimbare în educaţie nu ar putea începe, în zilele noastre, decât cu afirmarea rolului principal care revine cadrelor didactice în asumarea acestei schimbări şi cu sublinierea necesităţii de recuperare a principiilor pedagogice aplicate, în contextul actual dinamic, marcat de utilizarea noilor tehnologii pe toate palierele sociale, culturale şi profesionale."

"To learn is to acquire knowledge or skill. Learning also may involve a change in attitude or behavior."

For Dr. Howard Gardner, intelligence is:
"- the ability to create an effective product or offer a service that is valued in a culture;
- a set of skills that make it possible for a person to solve problems in life; - the potential for finding or creating solutions for problems, which involves gathering new knowledge.
"(Gardner 2009, American Psychologist and Educator)
Ref.: Building the 21st-Century Mind:

Computer and Learning

Results and performance obtained through the use of computers have boosted the development of all sciences. Man and the world interact continuously, reality is seen from multiple perspectives, the information we received through various channels so as to have an adequate response, the knowledge we have produced, not reproduced. Learning is individualized, and cognitive and emotional development plan can not ignore the cultural, social, technological. Computer inciting the ongoing reconfiguration of the image that we have about areas of knowledge by accessing different sources of information and provides another way to know and to produce knowledge. Learning is broadly defined as change. The focus can be on what we learn (the product of learning) or on how we learn (the process). It is about how we change and how we adapt, grow, and develop. This adaptation, growth, and development occur from the inside out. The 21st Century Skills are critically important to support the challenges of the modern work-place and the dynamic and rapidly changing knowledge society. Learning solutions focus on developing or enhancing the competencies and behaviors needed by individuals and teams in order to accomplish meaningful goals and create a positive work climate that encourages and values clarity, interaction, openness, diversity, community and results.

The triad "Learning-Knowledge-Development"

This conclusion lead to examine in detail the triad "Learning-Knowledge-Development" (Fig. 3):
Development - a process in which something passes by degrees to a different stage (especially a more advanced or mature stage); "the development of his ideas took many years"; "the evolution of Greek civilization"; "the slow development of her skill as a specialist or a person "; Sustainable development is maintaining a delicate balance between the human need to improve lifestyles and feeling of well-being on one hand, and preserving natural resources and ecosystems, on which we and future generations depend; This component is a physical environment; this treasure can store;
Knowledge – Knowledge is defined by the Oxford English Dictionary as (i) expertise, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject, (ii) what is known in a particular field or in total; facts and information or (iii) awareness or familiarity gained by experience of a fact or situation; the theoretical or; Knowledge acquisition involves complex cognitive processes: perception, learning, communication, association and reasoning. This component is a physical environment, but also a virtual environment; this treasure can store;
Learning - Learning is acquiring new knowledge, behaviors, skills, values, preferences or understanding, and may involve synthesizing different types of information. The ability to learn is possessed by humans, animals and some machines. Progress over time tends to follow learning curves. Human learning may occur as part of education or personal development. It may be goal-oriented and may be aided by motivation. The study of how learning occurs is part of neuropsychological, educational psychology, learning theory, and pedagogy; One way we use the cognitive processes in our daily lives is with learning. Learning is not just something we do in school or in formal settings. We learn every day. Sometimes our very survival depends on how well we can learn. That may mean unlearning our learned limitations and regaining confidence in our ability to direct our own learning. In today’s world, someone who doesn’t know how to learn is left behind (, 8 functions). By exploring your own learning process and determining your natural learning style, you can find the best ways for you to learn. Then you, not the instructor or the situation, are in charge of your learning. Learning is broadly defined as change. The focus can be on what we learn (the product of learning) or on how we learn (the process). It is about how we change and how we adapt, grow, and develop. This adaptation, growth, and development occur from the inside out. This component is only a virtual environment; this treasure cannot store.

NATURE & MATHEMATICS: "Laws of Nature are written in the language of mathematics". (Galileo Galilei)

INFORMATICS: "The informatics/computer science re-establishes not only the unity between the pure and the applied mathematical sciences, the concrete technique and the concrete mathematics, but also that between the natural sciences, the human being and the society. It restores the concepts of the abstract and the formal and makes peace between arts and science not only in the scientist' conscience, but in their philosophy as well." (Grigore C. Moisil)

MATHEMATICS: "If Mathematics was not "nothing would have been" no wheel and no computer, no press and no phone, no Computer Science or Cybernetics. But to all these entities materials invented by man, Mathematics helps man to think about life, create and imagine, to love nature and his fellows, to be emotional and brave, to be consistent and ordinary, to dream and be happy." (January 31, 2010, M. Vlada)

TEACHER: "A key role in promoting discipline among young people it is the teacher. It must fulfill its mission of teaching and teacher pedagogue using methods most appropriate discipline discovery by studying as many students. Teacher must his students not seeing the "good students" and "weak students", but "students" have to be guided to discover the knowledge and skills are encouraged to go through “step by step" learning and discovering the secrets of scientific knowledge." (February 1, 2010, M.Vlada)

GAUDEAMUS (video , Gaudeamus - Var-1 , Var-2 , Var-3 (Mario Lanza) )

Gaudeamus igitur
Iuvenes dum sumus.
Post iucundam iuventutem
Post molestam senectutem
Nos habebit humus.

Vita nostra brevis est
Brevi finietur.
Venit mors velociter
Rapit nos atrociter
Nemini parcetur.

Vivat academia!
Vivant professores!
Vivat membrum quodlibet!
Vivant membra quaelibet!
Semper sint in flore.

Să ne bucurăm, aşadar,
Cât încă suntem tineri
Fiindcă dup-o tinereţe agitată,
Şi-o bătrâneţe-ngreunată,
Ţărâna ne va avea pe toţi.

Viaţa ne este scurtă
Va fi terminată prea curând,
Moartea vine fulgerător
Atroce ne-agaţă-n ghearele-i.
Nimeni nu-i cruţat de-aceasta.

Trăiască şcoala!
Trăiască profesorii!
Trăiască fiecare-ntrebător!
Trăiască fiecare-ntrebătoare!
Fie ca ei să-nflorească de-a pururi!

Helicoidal Models

DNA vs. Software Development

1. "Helicoidal” models for DNA dynamics

2. The Helicoidal Life Cycle - Software Development

1. "Helicoidal” models for DNA dynamics
Deoxyribonucleic acid (DNA) is the nucleic acid that contains the hereditary information used in the development and functioning of all living organisms. The total genetic information in a cell is called its genome.

Ref.: Giuseppe Gaeta, Centre de Physique Théorique, Ecole Polytechnique, An amended version of simple “helicoidal” models for DNA dynamics

2. The Helicoidal Life Cycle - Software Development

Ref.: The Helicoidal Life Cycle – A Tool for Software Development and Enhancement
by Antonio Carlos Pinto Dias Alves, Unidade Gestão de Riscos
Rio de Janeiro, Brasil
"The Helicoidal Life Cycle allows superposition of different development phases, thus promoting saving time and costs. Although some phases can be completely superposed by others, each one can be tracked independently whereas the whole system development can be tracked by a separate helicoidal life cycle that covers the inner ones in an onion style. So, from the examples of use presented, we saw that reductions in development time and costs cannot be ignored. In some cases, those reductions reached almost 50%. May be, when CASE tools specifically designed for use with the helicoidal cycle be in use, savings can be even bigger."

Powers of Ten

UPDATE: Interactive Software - 2012 Scale of Universe by Cary and Michael Huang:
About Powers of Ten and Cosmic Zoom

"Powers of Ten takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker - with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell."
- |
- Cosmic Zoom : Discovery News,

"From a picnic blanket near Chicago out past the Virgo Cluster of Galaxies, every ten seconds the film pans out to show a square a factor of ten times larger on each side. The video then reverses, panning back in a factor of ten every two seconds and ends up inside a single proton. The Powers of Ten sequence is actually based on the book Cosmic View by Kees Boeke in 1957, as is a similar but mostly animated film Cosmic Zoom that was also created in the late 1960s. The changing perspectives are so enthralling and educational that sections have been recreated using more modern computerized techniques, including the first few minutes of the movie Contact, and in a short digital video called The Known Universe created last year for the American Museum of Natural History. Ray and husband Charles, the film's creators, were known as quite visionary spirits and even invented their own popular chair."
