Security system for Old Puzzle Solution Box

~sandhiya

Bharani from 9th grade has set an emergency alarm system in old puzzle solution box which gives a buzzer sound if someone opens the box.This prevents student from opening the box to see others answers.He used few materials like Battery,Buzzer,wires and clip.

 

 

 

 

 

The principle of this alarm is very simple.when someone opens the solution box ,the needle separating the clip is released , and the clip makes a closed circuit for the current flow which makes a sound.And also Bharani presented his project to his classmates and younger children in ISMART class. And students also tested his project.

Puzzle Solution Box

~Saranya, Murali, Abilash

Each week a Mathematical puzzle is placed on the STEM Land notice board, where the interested students who wants to solve the puzzle writes the answer and drops the answer in the Solution Box. The Solution box which they have been using was made of cardboard,that was pretty weak and did not have a Lock on it.The Students were worrying that the answers which they drop into the box may get spread among the others and wanted a Permanent solution where their answers were safe.

                            

So we(Saranya,Muruli,Abilash) planned of making a Stronger Solution Box. So we cut out the plywoods into the measured size and started nailing it. Seeing the half Solution box being ready, the students showed their interest by asking us if any help can be done by them.As still the Box was not completely ready and the hinges and latch needs to be fixed.We gave the remaining work that needs to be done to them.Though they were struggling a bit at the beginning ,soon they competed their work.And guess what….The Solution box was ready.

MES10 Reflection by STEM Team

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.

Poster Presentation

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.

 

Reflections of the team

 

 

 

Curious to learn new things

~saranya

During Math and activity period children suddenly picked up instruments and they came and asked how it works and it is  used for what? The instrument that they picked was BP(Blood Pressure)  instrument, temperature instrument  and ph meter……..Then we started explaining how to use also why it is used for. Children wanted measure the  BP also wanted to measure for their friends. They did it  and they were very happy.

 

 

 

 

 

Nirmal started working on waste batteries and he built one beautiful pen stand. It was not completed so agalya want to work on the waste batteries with poovizhi support. Finally they built one nice well shape. Now the well is using for breadboard stand.

MTA (Mathematics Teachers’ Association (INDIA )) Conference at Mumbai

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

Other Posters at the conference:

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.

 

Scratch course in Thamarai learning Centre

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.

Day 1:
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.

Day 2&3:
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.

Day 4&5:
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.

About STEM(Science Technology Engineering Mathematics) land

STEMLand is located in two outreach schools of
Auroville (Isai Ambalam and Udavi school). Children come to STEM Land for their Mathematics, EVS and science classes. They learn Mathematics, Electronics,
3D Printing, Programming, Mindstorms (Robotics) and learn to play strategic games that enhance logical thinking. The children take responsibility of their learning and plan their goals. They work individually, in pairs or peer groups and ask for support from facilitators when they need it. This self-directed learning is based on Sri Aurobindo’s first True principle of education (Aurobindo, 1910); “Nothing can be taught”. With younger children we work on real life projects that impact their surroundings. We believe a nurturing environment can support a child’s learning.

Isai Ambalam Shop EBD
In Isai Ambalam school the 7th and 8th graders had difficulty understanding profit and loss. On looking at the prices of stationary in the shops around they found that the price varied and the local shops in the village were charging too much. They also noted that it was not always easy for the younger children to have access to shops for small items they needed like pencils, erasers, scales, notebooks and their parents were not always able to get it for them. They started a small shop of needful things at the school during recess

Medicinal Garden
The children were keen on starting a medicinal garden at the school, when asked, the children said they were inspired by a session they had with a Siddha doctor in August. Children felt that a medicinal garden in the school can be used to cure minor diseases and discomforts and they could create an inventory of their own medicine. They also said that the garden would be useful for them as well as the future generations. Then children planned the location and chose it next to the washbasin so that the water used for washing hands could be reused to grow the plants

Elixir Course
Shanker (a web developer) who had attended the
python Django course offered at the iSMART
classroom, wanted to offer a course of his own on
Elixir. It was designed for 6 sessions in the month of September, across three weeks. Technically, it was a lighter course when compared to the Python Django. We learnt to design and create a simple phoenix project with the terminal, IEX commands, arithmetic operations and string functions. Feedback from the course indicated that the participants found it interesting and joyful.
8th Inspirational Festival (Mind Mingle)
Sanjeev and Arun were invited as guest speakers to the 8 th Inspirational Festival organized by Mind Mingle Helix and Rotary in Salem.The duo gave a brief introduction on STEMland. Then held a small workshop on Stewardship for all the speakers and participants. They received a good response from everybody Read more.
Learning about Indigenous cotton
 In Isai Ambalam school Deoyani Sarkhot and Pratap were working with the 7th and 8th graders on the importance of cultivating Indian cotton.They firsttalked about where cotton has been grown in India. They told the children that in West Bengal the best cotton is grown. Historically, muslin (a lightweight cotton cloth) was made from the best cotton in India Read more.
Scratch Course
A t Udavi school the 7 th graders had stepped in for
their Mathematics class for the first time in STEM
land this year. They saw their seniors work on
projects and some of them took the effort to work
with them, but we felt the need for a more rigorous
course for them. We used the first term holidays to
host a week long course on Scratch along with the
children at Udavi school

Independence Day Celebration 

This year we celebrated Sri Aurobindo’s Birthday and Independence day differently. Early in morning, 5 th to 8 th grade students went to see the birthday bonfire at
Matrimandir and spent some time in silence and meditation.The children then symbolically took the flame and ran from Town Hall, passed Solar Kitchen,Edyanchavadi, Kottakari, Alankuppam and reached Isai Ambalam School, and lit the firewood which was kept ready

Sets Game

A few girls from 10 th grade had built a physical game with a chart representing 3 venn diagrams (governed by 3 randomly selected rules by one team) and a set of 27 games pieces (3 shapes, 3 sizes and 3 colors). The other team players needs to place a piece on one of the areas and ask if it fits there. The goal is to figure out the original rules selected for each circle of the Venn Diagram and demonstrate the understanding of set theory Read more.

Bamboo Charkha

The children in 6th grade were not very sure of how the thread was made from cotton. In their textbook, they found a image of a Charkha. This got them enthusiastic and all the students wanted to make Charkhas.The class was split into two groups. Then they searched for resource materials in their school. Since our campus has many bamboo trees they came up with the idea to make charkhas using bamboos Read more.

Holiday EBD’s

During the 1 st term holiday children (5 th to 8 th grades) had come to school for half day sessions, to learn something new. There were different groups doing different projects. The EBD’s are Kitchen EBD(Read more), Automatic hacksaw(Read more) , Bi-directional People Counter (Read more) and Speed, Distance and Time (Read more)..

Sets game

A few girls from 10th grade had build a physical game with a chart representing 3 venn diagrams (governed by 3 randomly selected rules by one team) and a set of 27 games pieces (3 shapes, 3 sizes and 3 colors). The other team players needs to place a piece on one of the areas and ask if it fits there. The goal is to figure out the original rules selected for each circle of the Venn Diagram and demonstrate the understanding of set theory. A few 9th grade children choose set language as their goal as they played with this game. The game helped them in understanding the intersection of two and three sets. Then to make the game more interesting they modified the rules to guess the right answer within few attempts.

A 9th grader took this to the next level and did not just wanted to play the game on the chart but wanted to create a Scratch game to do the same. Children who did not know, and had the set language as in their syllabus learnt the concept by playing his game.

Fixing the 3D printer in STEMLand

The 3D printer in Stemland was not printing the model at the centre of the plate. It started to print the models at the corner of the plate. When I looked, I found that the trigger switch that was to locate the x-location was broken. So, I had bought a new trigger switch to replace the broken switch.

Pranavraj from 8th grade was working on the proof of the area of parallelogram is equal to the area of rectangle with same base and height. He wanted to create a 3D printed model for that. I supported him in creating the model using blender. Then as the 3D printer was broken he was not able to print the model. He helped me in replacing the trigger switch. Then we replaced the trigger switch. The new trigger switch is not able to get triggered when it hits the screw for the x location. This needs to be debugged.
