Me and Murali went to Aikiyam STEM land and gave a session on Geogebra. We started with asking children how to find the area of the square and rectangle. Children started tell all the misconceptions related to the topic. Children told all the key word that they knew. Then i drew and explained on the black board. Murali then explained and showed step by step to the children. Children understood how to find the area and perimeter. we wrote few questions on the black board and asked them to draw and to find the area using Geogebra software. Children learnt the unit to find the area. All the children were able to build build and solve the questions . Children also understand how many 1 cm / m square can be fit inside for the given area. The session went really well and children were able to find the area and perimeter at the end of the session.
On 2019/10/11 we had the third meet with the Scaling group. More information on the second meet can be found at : Link to previous session
This time Abilash started by sharing what he did in Auroville schools .We did the Siphon experiment which involves air and water pressure between two containers of water connected through a pipe.When the water levels are equal in the both containers,it attains equilibrium state.For more information refer the link below: Siphon experiments
Saravanan from Aikiyam has made maths materials like 1)integer game using number chart and 2 dice.It contains numbers starting from 0 to 89 (both positive and negative side).A target has to be set before starting the game i.e 25 (both positive and negative side). One die contains numbers from 4 to 9.Another die contains three (+) symbols and (-) symbols.Both dice should be rolled simultaneously.The number indicates number of boxes to move while the symbol indicates the direction to move.
2)A tool for Quadrilateral shapes with different angles using scales and pro-circles.
Sanjeev suggested Ganit mala and ganit rack to do integer calculations which should be easy for children to visualize and do calculations faster.
Three students from college came to STEM land for intern-ship for two weeks to learn programming in Scratch. We have asked them to create some project in scratch. They have created some videos projects on addition ,fraction, number line, multiplication, representing and arranging ascending order and descending order with squares. People from STEM land took Steward ship for new emergence for them . They took few tools from that session for them like stand , fear, deep listening and back ground conversation , four profile , CFSR sheet.
Reflection of the interns
Here are the list of projects that they made in scratch.
Children in 8th were doing rational numbers and they wanted to build a project to demonstrate their learning . They have build a project in number line. This scratch program shows how to find the fraction in a number line. The numerator is ( a random number is asked from the user. The program chooses a number 0 to 3 x the user number ) and the numerator is also generated randomly (2 – 10). The user needs to find the answer for the question. The user needs to give to a value for numerator and a value for the denominator.
From STEM land 3 people went to Bangalore for one intern in Aura. Their we wanted to do a session on electronics for the younger grade. Sanjeev’s sister is running a learning centre for the children. So we proposed her that we can conduct a course on electronics for about a 3 hour session for the children. we started the session at 10AM and ended at 1PM. First they learnt about Seven Segment Display(SSD). Children worked in a group of 3 in which boys and girls were mixed together. Then we introduced all the components that are required for lighting up their names using seven segment display. We had asked then to draw the structure of the seven segment display and to pin connection for each LED. Once they had found the pin connections , we introduced the bread board to them. Then children wrote their names in their notebook as it looks like in the seven segment display and understood how to lit up their name using SSD.
Children learnt how to how to use multimeter and check the voltage of the 9v battery, use 1k resistor and using breadboard and wiring up the circuit. Children were fully engaged for 3 hours and they didn’t get distracted by some things.I was inspired by the children when the class got over children collected all the components and kept them in their corresponding boxes. This shows that the children are responsible and want to keep their place clean.
At the end of the session we closed with reflections from each one of them. We had asked them what they learnt . Many of them said that they.
Learn to connect wire and connect a circuit. Cutting wire, Light up SSD,
Group made a word CAT using SSD, Connect a circuit using breadboard. Group MIA learnt to connect wire and build circuit and light up segment. One group made 39.76C using SSD. All things were new stuff for the children and they learn to work together as team. learnt to communication in group
Mathematics Education and Society 10th International Conference, Hyderabad, India Jan 28th – Feb 2nd, 2019
We went for an International Conference Which happened first time in Asia. It happened in Hyderabad university. The were 160 people from 20 different countries. It was a five day conference. We went to present a paper and a poster. In this conference they a plenary session in which one people will present a p[aper and the other 2 will respond to the presenter. Then 160 were divided into 5 small groups. Each group was about 20 to 25 people. Based on the plenary session from 25 people we again split into small group and discuss about the topic that happened in the plenary session. They also gave change for each group to ask a question. Then gathered in our group and discussed the questions. Among these question we selected a question and asked it to the presenter. The presenters answered the questions. Everyday in the afternoon we had a parallel session on presenting the paper. Paper presentation
Pratap and Poovizhi presented a paper on “factors that influence children attitude towards mathematics”. To read the paper click here.
There were about 55 people for our session and we presented in front of them. Generally it was 10 minutes presentation and 20 minutes for discussion about the paper. But for us we presented for 10 minutes and discussion happened for 40 minutes the paper was well receive by the people. After presenting the paper one of the parent came to us and she wanted her child to admit in our school. That moment we felt that we are doing a big change in the world. Some of them wanted to set-up STEM in their school and they were asking many question about the STEM land school.
On the next day Arun presented a poster on Deep learning of mathematics by building projects and we supported him. It was also well received by the people and some wanted to implement our method in their schools.
The conference was happening for three days. There were about 100 people from different states. We wrote a paper on how children can learn mathematics by building project using physical technology eg. building / construction. Virtual technology such as programming. Children can also learn conceptual ideas by programming a computer. It helps them to break down their ideas into smaller bites for a computer to follow. At the conference we met many people who are working on the Maths education. People who were attending the conference were school teachers, college professors and some research people.
They were many paper presentations happening and debate were happening about mathematics. Most of them talked about the Mathematics at college level. There was a technology session happened using with GeoGebra. Where they introduced how to use this software. They showed how to find the angles and how to draw a parallelogram. They introduced all the tools to us on how to use GeoGebra. To learn more about Technology session Click here

As I went for Epistemy7 conference. From my conference experience going with Sanjeev to the Epistemy7 I had just followed everything what he had told in Epistemy7. I followed those things in MTA conference. I had a check list and also created a directory structure with everything that I am going to present. There were about 30 poster and we need to present in an hour. Most of the people visited our poster and I was happy that we were able present our poster to everyone. We also asked people to sign up their Email ID to send further information. Since I took initiative to present the paper I was well prepared for the presentation. I also met many people who had already came for the Epistemy7 last year.
In Thamarai Learning Centre STEM land team offered a basic scratch course in the evening for 5 days from 5.30 PM to 7 PM. The facilitator in that centre didn’t know about scratch so they also joined the course. There were about 15 children and 4 facilitators.
First day we introduced the different blocks and its function in scratch. Children started to explore and were excited in exploring the different options in Scratch. We have asked the children to create 10 question and answers. Then we introduced how to have a conversation between two people. Initially we showed them how to make a conversation with the 10 question. Slowly children started doing it on their own. They learnt to use ‘sensing’ and ‘=’ operators to ask 10 questions. When the wrong answer is typed, the same question should be asked again until the user gives the correct answer.
We introduced the pen function and motion function. Using these functions we showed them how to draw with and object and also to move a objects. Once when they were able to finish we had asked them to draw a triangle. They didn’t want to give up and after 15 minutes they figured it out. Then we asked them to draw a square, pentagon,hexagon, heptagon, octagon. Then they were able to draw different types of mandalas using ‘rotate’ block.
We had introduced children hoe to build a maze game. We showed how to move a object when a key is pressed. Children worked in pairs with each other to create a maze path in the backdrop image. They were able to use sensing function and also become familiar with motion function.
Everyday we asked children to sit in a circle at end of the session for 10 minutes. We asked them to share one thing that they learnt in the session. All the children share something that they learnt.
Most of the children loved and enjoyed building their own game. This created confidence in children that they can make many things using scratch.
In STEM land a person from Auroville came to the iSMART class to conduct a course about raspberry pi course. Initially I dont know how to use raspberry pi. I was curious to learn raspberry pi. I also learnt the differences and advantages between Arduino and Raspberry pi. I learnt the different pin functions and the number of pins on a raspberry pi board. Day 1&2 was fully theory session which was boring.
In order to make it interesting I started ask many question to the teacher and the session was engaged by the participants. What really was interesting in the course was that the Arduino can’t drive a relay but with a raspberry pie we can drive a relay. One the teacher told that a relay can be driven by rapberry, he had a relay module but he couldn’t drive it. I took as a challenge and struggled for two days and I figured it to drive a relay. We made a small circuit with 2 LED where when the relay is on one of that LED will turn on and when the relay is off the other LED will turn on.
After this the teacher was also very happy and he also learnt something from us. Then the next challenge was that to send and to receive inputs from a raspberry pi to a web page.The teacher had asked who knows web page development.
Since I learnt Django web framework in STEM land, I was able to connect What I knew with what I lean now. So I had asked him to show an example how to pass inputs from raspberry to a web page. Then finally in the last class we were able to complete all the task that we planed to accomplish in the course. Now I have some knowledge about raspberry pi and also I can build something with it.
