Savarirayalu nayakar govt girls high school is applying for a national award in ICT and asked our support on Scratch and Geogebra. Children from 8th and 9th grade were interested to learn. On the first day we did a scratch course. We gave them a task to ask multiple questions and if the answer is correct it’ll move on to the next question else it’ll ask the same question until it is correct. Children were able to use controls and were able to find the logic. The next two days we did a course on Geogebra. Children first explored all the tools available in Geogebra and then drew an equilateral triangle. Some of the children drew it using regular polygon. Then we asked them to draw equilateral triangle by finding the intersection point. They used two circles and found the intersection point and were able to draw the triangle. Then we asked them to draw different triangles and find the sum of the angles of all the triangle. They found that the sum of all three angles of a triangle is 180 degree for all triangle.
On second day, we asked them to draw circle and to find out ratio of circumference and diameter of different circle.They found that the ratio of circumference and diameter is 3.14 (Pi value) for all circle. Then, we asked them to draw chord line on circles and make a triangle by choosing a point on circles with chord as a base of triangle and measure the angles of triangles. Then we asked them to find out the pattern in triangles in different circle. They found that the angle for all triangle at third vertex point on one section of circle is same and different from angle on other section of circle which are separated by chord line on circle and also the sum of angles of both section of circle is always 180 degree for all circle with different chord length.
There are many things mater in analog passes for success (I.e noise,bandwidth,amplitude and frequency). I learnt few difference between analog layout and digital layout. Compare to digital layout it occupies less space and looks neat. We started doing step by step orthogonality, fourier series, exponential & expansion as sequence, laplace transform. First we did theoretical part that is Rc (Resistor and Capacitor) circuit with the input of sine wave and unit step function. By using exponential and laplace transform we found the output of unit step and sine wave in RC circuit. Now I have started calculating sheet resistance of each component (poly,metal,contact,etc..) that we will use it in magic tool.
We presented our paper about STEM land in Udavi and Isai ambalam in The Bridge a collaborative research in Auroville. Our paper was under unending education on 25th Feb 2018. We started the presentation with the core values of STEM land and about the activities and interventions in STEM land. And continued with the plans and tracking method that we follow in STEM land. Then we shared about the Leadership in action program that we do with children and few examples of how it had benefited them to be responsible.
Then we shared about the learning environment in STEM land where there is no hierarchy and learning becomes a social activity and spreads without one to one inputs from facilitators. We also pointed out how STEM is moving towards STEAM and the outcome of children after coming to STEM land. Then we shared about STEM land in Isaiambalam.
We explained about the real life challenges that children take up and how they solve it through EBD. People enjoyed the session and happy to see children work. We showed them few pictures of children working on their EBD and the designs they have build like, Pond, honey bee, Bamboo torch, garden and kitchen waste water management. People enjoyed the presentation and were interested to know more about STEM land.
Around 37 gevernment school teachers and people from Azim Premji unversity visited STEM land. We presented a paper on “STEM land in Isaiambalam school” at Sindhanai Sangamam symposium. Some of them were inspired from our talk and they came to visit STEM land. People saw what the children were upto in Isaiambalam school. We had a saturday school and all the children were working on the EBDs.
After that they visited STEM land in Udavi school. Children showed them few projects. The teachers also tried to solve caste puzzles. We also conducted a Stewardship session for the them lead by Sanjeev.
We have started with the story of linear equation. Linear equation is nothing but a straight line and choice. For an example we have taken x+y=10. The story of the linear equation is, I and my brother likes chocolates if I get more chocolate obviously he is going to get less chocolate that is the story of the linear equation. After that we have entered into the problem. We started drawing the line for that equation.First I have drawn wrongly for that equation x+y=10. What I have Thought is when the x increases y also get increase equally so the point is (10,10) that is why I have drawn like that. After that I have understood the function of linear equation. In that linear equation it will get increases by 10 on both the axis.
When I learned how to draw a linear equation. I have made my own question that is x+y=20. Then I have checked my equation using geogebra.
How to make a concrete structure using cement, jelly and sand. Children wanted to make a beam around the pond. To make a beam they wanted to they need a iron rods. We bought the iron rods and the tools to bend the rod into a rectangular structure. First time when I made a TMT Ring it didn’t come in proper way. 5th time I got it correctly. Children were excited and they were watching me seriously. They found the patterns and how to bent the iron rod. One child from 4th standard took effort to draw the actual ring size using a on the surface where I was making the rings. Then Children started to do and they found the pattern how to bend the rings. They told the that they need to bend it 90 degree. All the children used the ring structure that the boy drew which was very useful to bend the ring at the right size.
RYSI (Raman Young Science Innovator) When we got the circular about Raman award. Students were so excited to do many things in different ways.I have supported few of them.It was different experienced with each children. One of the student is from 9th grade, he wants to measure the frequency.We have connected one micro phone with an Oscilloscope.With the help of an Oscilloscope we measured our heart beat frequency.
I learned about Density(formula). In water, if we place a stone in water, it will sink because the density of the stone is greater than 1. If the density of an object is in less than 1 it will float in the water. Sharani from 5th grade she did density project for Raman award. I just supported her. That was nice experienced with her.
In scratch, I learned to give input from the keyboard using sensing(tool). I have drawn a circle using scratch. Inside the program no need to give radius value I have given radius value from the keyboard.That was new for me.
About 22 principals of various schools from mind mingle had come to Auroville to visit schools in and around Auroville. They were split into two groups and one of the groups came to STEM land. They were about 10 principals. We gave a broader picture of what we do and how children learn in STEM land.
Then they went around STEM land and interacted with children. They saw the weekly puzzle, weekly plan. Children showed them how they fill their plan using the software, Hariharan solved Rubiks cube, on the other side Viknesh and kabilan were demonstrating their Makey Makey project in which they made a mouse using a rubber chapel.
They looked at the Montessori materials. At the next room children were printing a fidget spinner in 3D printer, some of them were working on Alice and scratch.
The principals were happy to see children printing 3D models and sat along with the children to learn how it works. Children showed their projects which they made in Scratch, Geogebra and Alice. Children gave the principals some cast puzzles and asked them to solve it. Some of them played games along with the children.
It was interesting to see children sharing their learnings with the principals from various states without any hierarchies. Each one of the teachers learnt something from the children and were happy to be STEM land. At the end they wrote about how they felt being in STEM land. They said STEM land is a nice learning environment with freedom. One of the principals said that she was touched with what we do and wanted to implement it by herself.
Jan 22 is my first day as volunteer in STEM land. On that day, we attended the stewardship workshop along with the children in Udavi. The first session was on sourcing inner power where I was able to process my stand and fear. I noticed that my stand supports me, when I face failure and losing something. I have also got an answer of why I am in STEM land.
The next day at isai ambalam school, i figured out that i want to learn more about who i am and what makes me complete being. In afternoon, we had a meeting with heidi regarding regarding the research papers based on what is done in STEM land. During the session she taught us how we could conduct an effective survey with the children. Then i learned to display names using 7-segment LED displays and to blink them using astable multi-vibrator.
On Jan 24th and 25th we went to Indira Gandhi higher secondary school for Learning festival. I felt really happy when i was helping children to display their names using 7-segment LED displays. Initially some children didn’t understand english and were not interested in it. I guided them step by step in their mother tongue. Then they showed lot of interest and become familiar with me. At end of each session, all childrens are able to display their names using 7-segment LED displays and also understand, why human get stock when they touch power cable in their house but not with TV remote battery. They learned how resistor controls current in circuit with analogy of rubber shoe while working with power line. Finally they became expert in displaying their name in LEDs and they became teachers for their teachers.
At STEM land -AAD our tag line is learn, grow, work, teach. We work in various ways on our growth. I recently participate in a Vipassana course. I found it useful in various ways.
I am noting my understanding of the technique of Vipassana based on my experience, the evening discourses and from the conversations about it later.
1) What is taught at Vipassana is Sila, Samadhi and Panna. a)Sila is the morality.
* Do not kill any living being
* Do not tell lie
* Do not steal
* Do not take any type of drugs
* No sexual misconduct Why? When we break Sila it needs a strong volition of the mind. This is the volition we are trying to dissolve through Vipassana.
b) Samadhi is concentration of the mind
Anna-panna helps us to concentrate by concentrating on breath. We choose breath to concentrate because it is the universal Truth and everyone can experience it.
It also links with breath which changes with emotions and allows to notice ourselves.
This is Samma-Samadhi the right kind of Samadhi.
It can also teach equanimity by not having attachment to breath that comes in or goes out.
It also helps us to understand the law of nature that is impermanence (Anicha) that is ‘constantly changing’.
c)Panna is wisdom
Suthamaya panna – wisdom I get when I listen to someone I respect or have faith in
Chintamaya panna – wisdom from thinking about something and understanding intellectually
Bhavanamaya panna – wisdom gained from the Truth experienced by me Vipasana focusses on Bhavanamaya panna
We notice that mind and matter are related
2) We have 6 sense doors – 5 external (see, hear, smell, taste, touch) and the mind that brings a thought.
Phassa – contact with 6 sense doors results in
tanha – identify or gives decision
sankara – craving and aversion. The subconscious mind reacts to the sensation in this way.
Phassa leads to vinyana leads to tanaha leads to vedhana leads to sankara Vipassana gives us access to change the habit pattern of our subconscious mind of craving and aversion.
We are aware of only 2% of our thoughts, this gives us access to train the 98% of our thoughts.
3) The two important wheels of Vipassana are awareness of sensations and equanimity. Without awareness of sensations we cannot get to the subconscious mind. Without equanimity we cannot change its habit pattern of reaction.
4) Metta – share my unconditional peace, love and happiness with others and care for all living beings.
