A view of greater Mumbai (Bombay) using an image gathered by the NASA and USGS Landsat 8 satellite on Sunday February 23rd, 2014. Gray areas are built up urban parts of the megalopolis. There are significant areas of “green space” in Mumbai’s hinterlands as revealed by the image. These areas, such as Borovali National Park and several mangrove-laced estuaries show up as red and deep red in this false-color image. The satellite is picking up 11 different multi-spectral layers of data-most of which are not visible to the human eye. The 5,4,3 band combination emphasizes vegetation by assigning the infrared band to the color red while leaving green and blue with their normal bands. Other notable features include the Bandra Sea Link, Chhatrapati Shivaji airport, Elephanta Island and numerous ships in the ocean. Click on image to see enlarged A3 version at 150 DP

Back at ASB, after the morning visit to Elephanta, I enjoyed three invigoration days of thought- provoking demonstrations, workshops, lectures, interactions and talks at the ASB Unplugged. The workshops were crowded with 400 or so participants from across the globe and we were joined by the ASB staff, students and staff. The three days were split between student demonstrations, classroom visits and then “hands-on” learning institutes. The first day was capped with a Tedx talk.

There were many personal outcomes that I got out of the conference: I relished learning about strategies for effectively integrating technology in my classroom, interacting with students about their personal application of technology in the DP and CAS programs and sitting in on several excellent interactive lectures by learned experts. It was difficult trying to choose from the myriad workshops but my choices of Larry Rosen’s Brain-Based Learning workshop and Suzie Boss’ Project-Based learning were just right for my own needs. It was good being part of a whole school team approach and the six of us OSC participants regrouped frequently to share learning and outcomes from various workshops. Our family friend Alok Parashar is ASB’s head of administration and we reminiscing about our years together on MUWCI’s distant hilltop. Interestingly, there were no geo-spatial workshops on offer and it appears to me that this is a key deficiency in the program that will perhaps offer an opportunity to address at the next conference. Thinking about this, I started the download of a Landsat compressed file of Mumbai (taken just five days earlier) from Earth Explorer on the first night. It has taken several hours of processing and has helped me rediscover this neck of India that I know well from a decade ago. The image above is the outcome of that process. I have also started working with several other cloud free images from the Pune, Nashik and Ratnagiri areas.

ASB is an impressive learning community and they are blessed with outstanding resources. Like anyone in Mumbai and other urban areas in India they face a challenge in the day-to-day reminder of extreme income disparities in society-something there are few quick fixes for. Perhaps what is most interesting to me is their singular focus on their mission and purpose. The focus on innovation and creativity at all levels of the school is something that many of us could learn from. The space and time given for students and teachers to apply learning in practical ways was energizing. ASB’s Superintendent, Craig Johnson, passionately articulated this in his welcome and concluding speeches. These were positive ideas to bring back with us to Colombo. What they didn’t have in Mumbai was the greenery, fresh air, island hospitality, spicy sambol and quiet neighborhoods that are a blessing to the OSC community and it was with happiness that I returned to my family in the eastern suburbs of Sri Lanka’s capital city!
