5 Alternative Teaching Methods

The common features of these methods are:

  1. All of these methods are against indoctrination. 
  2. They support “self-learning.” 
  3. They believe that a child is capable of learning by oneself.
  4. Best learning is hands on and experienced with all senses.
  5. One should feel free to make mistakes and learn from them.
  6. Learning should be free of evaluation by others.

These methods are summarized as follows.

1. MONTESSORI

  1. Children are born with absorbent minds and are fully capable of self-directed learning. They are not born as “blank slates.”
  2. Educational environment should empower children with the freedom to choose how they spend their time in school. In such environment children would seek out opportunities to learn on their own.
  3. Structured lessons and teacher-driven curriculum inhibit a child’s natural development. Children enjoy and need periods of long concentration.
  4. Most learning takes place through tactile sensation.
  5. Education should be non-competitive without grades, tests and other forms of formal assessments.
  6. Evidence shows that Montessori education leads to children with better social and academic skills.

2. STEINER/WALDORF

  1. Humans have the inherent wisdom to uncover the mysteries of the world.
  2. Education should focus on the development of the “whole child,” with an emphasis on creative expression and social and spiritual values.
  3. First 7 years of a child’s life (up to 2nd grade) should be marked by imitative and sensory-based learning and devoted to developing a child’s non-cognitive abilities. Kindergartners are encouraged to play and interact with their environment. Children are encouraged to write before they learn to read.
  4. From age 7-14, creativity and imagination are emphasized, including learning of foreign languages and expressive dance and performing arts. Demands for standardized testing are restricted.
  5. By age 14, students are ready for a more structured environment that stresses social responsibility.

3. HARKNESS

  1. The educational method involves all students in the learning process. It is an approach designed to get at the individual boy.
  2. Students sit with their classmates and teacher around a large oval table and discuss any and all subjects, from calculus to history, often in great detail. Individual opinions are formed, raised, rejected, and revised.
  3. The teacher’s main responsibilities are to ensure that no one student dominates the discussion and to keep the students on point. No conversation is ever the same.
  4. The group is small enough so that the shy or slow individual is not submerged.
  5. The intimate setting of the Harkness table forces students to take responsibility for their own learning and encourages them to share their opinions.
  6. In addition to learning about topics being discussed, students also learn valuable public speaking skills and to be respectful of their fellow students’ ideas.
  7. Studies have supported the method’s effectiveness in increasing students’ retention and recall of material.

4. REGGIO EMILIA

  1. Children are competent, curious and confident individuals who can thrive in a self-guided learning environment where mutual respect between teacher and student is paramount.
  2. This educational approach is about exploring the world together and supporting children’s thinking rather than just giving them ready-made answers.
  3. This approach is most important for teaching children aged 3 to 6.
  4. It emphasizes the importance of parents taking an active role in their child’s early education.
  5. Classrooms are designed to look and feel like home and the curriculum is flexible, as there are no set lesson plans.  Emphasis is placed on art and on a variety of creative projects.
  6. Extensive documentation of a child’s development, including folders of artwork and notes about the stories behind each piece of art, is kept.

5. SUDBURY

  1. The basic postulate is that students are inherently motivated to learn. Students are capable of assuming a certain level of responsibility and of making sound decisions. In the event that they make poor decisions, learning comes in the form of dealing with the consequences.
  2. Sudbury schools operate under the basic tenets of individuality and democracy and take both principles to extremes. Students have complete control over what and how they learn, as well as how they are evaluated, if at all.
  3. At the weekly School Meeting, students vote on everything from school rules and how to spend the budget to whether staff members should be rehired. Every student and staff member has a vote and all votes count equally.
  4. Students regularly engage in collaborative learning, with the older students often mentoring the younger students.
  5. Annual tuition for the Sudbury Valley School, which welcomes students as young as 4 years old, is $6,450 for the first child in a family to attend the school.

Build a School in the Cloud

Reference: Subject: Education

You may read the transcript here.

Here are the main points from this talk (February 2013):

(1) The current schooling system was designed to meet the administrative requirements of the far flung British Empire of 1700s, which were as follows,

  • The graduates must be identical to each other.
  • They must have good handwriting, because the data is handwritten.
  • They must be able to read. They must be able to do multiplication, division, addition and subtraction in their head.

(2) This schooling system does not have DISCERNMENT as its requirement. But that is the requirement we need to meet today. We need education that produces people who are able to discern what they study, because they are going to be faced with increasingly dynamic job market.

(3) Computer somehow seems to excite the children’s desire to learn.  Experiments show that children learn to browse and play the games on computer by themselves.  They even learn enough English themselves for this purpose.  They easily learn about computer parts and their function.

(4) In nine months, a group of children left alone with a computer in any language will reach the same standard as an office secretary in the West.

(5) A speech-to-text engine in the computer was able to improve English pronunciation of the children. Children could even learn “biotechnology of DNA replication in English” to some degree when they were told that it was an important topic to know. Their scores improved even further when their efforts to self-learn were encouraged and admired.

(6) Today learning is more interesting and effective through cell phones than through books and schools. We now have almost instant access to information that we need to know. Does that make knowing obsolete? Encouragement seems to be the key to self-learning.

(7) Any threat tends to shuts the brain down. In the age of Empires, it was important to teach how to learn and survive under threat. Today we need to teach to bring out creativity.

(8) We notice from these experiments that learning is the product of educational self-organization. If you allow the educational process to self-organize, then learning emerges. It’s not about making learning happen. It’s about letting it happen. The teacher sets the process in motion and then she stands back in awe and watches as learning happens.

(9) Self-Organized Learning Environments (SOLE) are collaboration and encouragement put together. Ask big enticing questions. Then give the child a hint and relevant materials. He will figure it out.

(10) We can design a future of learning by supporting children all over the world to tap into their wonder and their ability to work together. It will be a school where children go on these intellectual adventures driven by the big questions which their mediators put in. It’s a facility which is practically unmanned. There’s only one granny who manages health and safety. The rest of it is from the cloud.

KHTK Postulates for Physics – Part 2 (old)

atom3

Please see Course on Subject Clearing

KHTK Postulate P6: The speed of propagation of electromagnetic disturbance decreases with increasing inertia of disturbance levels.

As inertia increases with disturbance levels it offers greater resistance to the propagation of disturbance. The constant for the speed of light (3 x 108 meters per second) applies only to a narrow band of the electromagnetic spectrum at DL49. It is expected that radio waves (DL27) propagate at a higher speed, and the gamma rays (DL65) propagate at a slower speed than the speed of light.

.

KHTK Postulate P7: The electromagnetic disturbance propagates in the form of discrete wave packets of finite number of wavelengths.

The electromagnetic disturbance propagates in the form of wave packets much like puffs of smoke.  These wave packets are very long and “snake like” at low disturbance levels. At higher disturbance levels the wavelengths are small and these wave packets may look more like “golf balls.”

.

KHTK Postulate P8: Particle-like properties come to dominate at higher disturbance levels.

At lower disturbance levels the wave packets are extended over long distance and behave like waves. At higher disturbance levels spacetime condenses and the wave packet increasingly assumes the appearance of a particle. Higher inertia and condensation of spacetime expresses itself first as charge, and then as mass associated with the particle.

At the level of electrons, inertia expresses itself both as charge and mass. An electron is still spread over some distance to display wavelike properties, while compact enough to display some particle like properties of mass. It seems that Heisenberg’s uncertainty principle comes into play when the electron is assumed to be like a “golf ball” rather than like a “snake.”

This ratio of mass to charge increases with increasing disturbance levels. At much higher disturbance levels, even the charge seems to “condense” into mass from electron to proton to neutron.

.

KHTK Postulate P9: The location of an object in this universe is only as certain as its inertia.

The stars and planets in this universe are massive and can be located with precision. However, the electrons in an atom have very little mass or inertia. They can be located in highly probabilistic terms only. Thus, it appears that the higher is the inertia of an object, the greater is the certainty with which it may be located as a discrete entity.

.

KHTK Postulate P10: The universe is made of multi-layered spacetime.

Each disturbance level acts like a unique layer of inertia and spacetime. Together, these layers of inertia and spacetime seem to make up this universe.

The fundamental inertial and spacetime characteristics of solid objects (> DL100) shall be very different from inertial and spacetime characteristics of light at DL50. We cannot reasonably compare the speed of a solid object with the speed of light in a framework based on solid objects (> DL100). We may reasonably compare such speeds only in a framework based on space (DL0).

The theory of relativity is flawed to the degree that it is “earth centric” and not “space centric.”

Thinking Out of the Box

pebble8

This is an old story but it is worth putting on this blog:

Many hundreds of years ago in a small Italian town, a merchant had the misfortune of owing a large sum of money to the moneylender. The moneylender, who was old and ugly, fancied the merchant’s beautiful daughter so he proposed a bargain. He said he would forgo the merchant’s debt if he could marry the daughter. Both the merchant and his daughter were horrified by the proposal.

The moneylender told them that he would put a black pebble and a white pebble into an empty bag. The girl would then have to pick one pebble from the bag. If she picked the black pebble, she would become the moneylender’s wife and her father’s debt would be forgiven. If she picked the white pebble she need not marry him and her father’s debt would still be forgiven. But if she refused to pick a pebble, her father would be thrown into jail.

They were standing on a pebble strewn path in the merchant’s garden. As they talked, the moneylender bent over to pick up two pebbles. As he picked them up, the sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick her pebble from the bag.

What would you have done if you were the girl? If you had to advise her, what would you have told her? Careful analysis would produce three possibilities:

1. The girl should refuse to take a pebble.
2. The girl should show that there were two black pebbles in the bag and expose the moneylender as a cheat.
3. The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment.

The above story is used with the hope that it will make us appreciate the difference between lateral and logical thinking.

The girl put her hand into the money bag and drew out a pebble. Without looking at it, she fumbled and let it fall onto the pebble-strewn path where it immediately became lost among all the other pebbles.*

“Oh! How clumsy of me,” she said. “But never mind, if you look into the bag for the one that is left, you will be able to tell which pebble I picked.” Since the remaining pebble is black, it must be assumed that she had picked the white one. And since the moneylender dared not admit his dishonesty, the girl changed what seemed an impossible situation into an advantageous one.

*MORAL OF THE STORY: Most complex problems do have a solution, sometimes we have to think about them in a different way.*
