STERLITE NEWSRO0M Sterlite Technologies helps Tata Power augment power carrying capacity for a critical Mumbai line Pune, India – August 13, 2013: Sterlite Technologies Limited announced that it has completed installation and commissioning of a challenging project in the heart of Mumbai requiring significant up-gradation in the power carrying capacity for a critical line of Tata Power. Sterlite executed this turnkey project for Tata Power – a leading T&D utility in India. The project involved rendering of services like design, supply and installation of high capacity, high strength carbon composite core conductors on an existing critical arterial 22 kV line delivering power to a number of industrial customers and a local college. This unique solution has resulted in an exponential increase in the power transmission capacity of the existing IIT Powai to Saki transmission line that criss-crossed over a thickly populated slum area comprising closely spaced hutments and hilly terrain. “The lines on which ACCC conductors have been installed are very old lines traversing through populated areas,” The idea was to go for lightweight conductor so that we can retain our existing structures and augment the line capacity.” says M V Deodhar, Assistant Engineer – Projects, Tata Power. “ “Until now the conductor has been loaded up to 480 Amperes and so far its performance has been satisfactory. We have been observing the performance/ behaviour of the conductor under faults, and so far the conductor is not subjected to fault condition,” aﬃrms Deodhar. The line would realise its promised throughput as soon as the substation upgradation gets completed. "Higher capacity, reduced sag and lighter weight translate into lower project costs that provide economic advantages when upgrading an existing line with minimal structural modifications or installing a new line with fewer or shorter structures – definitely a vital step towards our utility customer engagements,” says K S Rao, COO – Telecom & Power Conductors, Sterlite Technologies Limited. SEPTEMBER 2013
Sterlite launches enhanced family of bend-insensitive fibers Pune, India – July 18, 2013: Sterlite Technologies Limited announced the launch of three new products in its bend-insensitive BOW LITE family of fibers. These include the brand new BOW LITE SUPER (G.657 B3), and significantly improved BOW LITE PLUS (G.657 A1) and BOW LITE ENHANCED (G.657 A2.B2) fibers. Optical fiber cables in FTTH networks experience several tight bends, especially in distribution section of the network, drop cables found in Multi Dwelling Units, and cables inside the homes. The use of bend insensitive G.657 fibers in FTTH installations is required as carriers have to contend with tight power budgets, and uncertain deployment conditions needing healthy safety margins. With its significantly low macro bend loss and attenuation, Sterlite family of bend insensitive fibers are the perfect solution to the carriers’ FTTH needs, suited to all FTTH architectures and deployment conditions. Furthermore, Sterlite is one of the few manufacturers in the world with the scale to oﬀer novel products for such applications. Dr. Badri Gomatam, Chief Technology Oﬃcer, Sterlite Technologies Limited, stated, “We are very pleased with the launch of these products. Being committed to innovation in the core market segments we serve, these new fibers augment Sterlite's product portfolio in optical fibers, and positions Sterlite well in addressing the growing demand for telecommunications infrastructure in India and abroad.” The BOW LITE series complies or exceeds ITU Recommendations and IEC 60793-2-50 optical fiber specification.

FORTHCOMING EVENTS FUTURECOM 2013 Rio de Janeiro, Brazil October 21-24, 2013
Cabling within the Home - Stephen Hough Delivering optical fibre cable inside a home environment introduces several challenges. This article attempts to identify the challenges and to provide points of consideration when installing fibre into a home environment. Optical cabling within the home is a fairly new concept, born from a need to meet the demands for the increased data rates that are necessary to exploit technological advances in home entertainment and internet usage. It is recognized that optical fibre is the most eﬃcient method of carrying high data rates and so minimizing the distance between the fibre and the active equipment has its attractions. However, the three major points of concern when considering health and safety include risk of eye damage, risk of skin contamination & infection and risk of allergic reaction.
might harm the cornea or lens and therefore risks damaging the eye. The transmitted light is infrared and so you cannot see it, which means you cannot tell if there is light present just by l ooking at it.
Chemical Cleaners: Optical fibre splicing and termination use chemical cleaners during the processes and should only be
Laser light sources Optical sources used in fibre optics, especially in premises networks are of much lower power levels than used for laser surgery or cutting materials. The light that exits an optical fibre is also spreading out in a cone, so the farther away from the end of the fibre your eye is, the lower the amount of power your eye receives. The infrared light in fibre optic links is at a wavelength that cannot penetrate your eye easily because it's absorbed by the water in your eyeball. Light in the 1300-1550 nm range is unlikely to damage your retina, but 4
Glass Fibre Shards: Fibre shards are dangerous. As part of a termination and splicing process, small ends of fibre (glass shards) can be produced. The shards are easily dropped and can be picked up on the skin, creating a risk of transfer to the eyes, creating a risk of blindness. In addition, there is a danger that the fibre shards will pierce into the skin; invariably they break oﬀ and are extremely diﬃcult to remove, which can result in infection.
used in well-ventilated areas as they can aﬀect a person’s breathing. There is an additional risk of allergic reaction to the cleaning agents. Smoke and Halogen Inhalation: The sheathing used for indoor cables in must be manufactured using low smoke and zero halogen (LSZH) materials to minimise the risk of the inhalation of toxins in the event of a fire.
TECHNOLOGY Recommendation This article assumes that the fibre installation will be post building construction and that the cable will be installed within the inhabitable environment. To minimise health and safety risk, the convention is to avoid fibre connectorisation in the home or working environment. If the chosen installation methodology introduces a splice into the home, it should be terminated as close as possible to the point of entry, or placed in a location away from normal activity such as a cupboard, then use the preterminated fibre cable to carry the service to the active equipment. Pre-terminated cable includes but isn’t limited to patch cords. It can also include multiple cables, also known as hydras and pigtails. Pigtails can be very small and delicate single ended cables, which are usually used for connection to cable fibres when inside fibre management systems; however they can also be ruggedized single ended cables, with an intended spliced termination at one end and connectorised at the other end for connection to the customer’s active equipment. All cables used within a home environment must be manufactured using LSZH internal grade sheath materials. Cable Routing: The equipment location, will define the necessary cable type. If located close to the fibre point of entry, then a conventional 3mm diameter enduser fibre pigtail or patch cord from the entry point to the equipment will be adequate, as it will be a relatively short transition. However when the equipment is located at a distance from the point of entry further challenges are introduced.
Demarcation: Conventionally known as network termination equipment (NTE) or alternatively for an optical SEPTEMBER 2013
implementation, as the optical network terminal (ONT); the demarcation point is w h e r e a n o p e r a t o r ’s n e t w o r k i s terminated and ownership passes to the home owner. Dependent on the installation methodology, the demarcation point can be located outside of the home, either directly on to the building wall or remotely; inside the home at the point of access into the building; in the room where the active equipment is located, which can be separate from the consumer’s personal equipment, or can be in the same location. Demarcation outside of the home has its own challenges, which should also be considered prior to any installation; however this article only considers demarcation inside of the home.
door frames etc and have been designed to maintain a low profile and where possible to blend into the aesthetic styling of the room. Conduit is usually supplied in either white, oﬀ white or brown and can be provided in a variety of shapes and styles.
The advantages of conduit include:
Fibre Cable Transportation: There are two conventions for routing fibre cable within the home in pre-established rooms;
• The ability to fix it to the wall using either mechanical fixings or adhesives. (Note: It is recommended that for solid walls construction, mechanical fixings are used. Dependent on the condition of the walls, the fixings can be masonry nails, or screws with fixing plugs).
• Can be attached to most wall surfaces.
• Easy handling and storage of the fibre cable.
The chosen method will be dependent the room design, construction materials and aesthetics. • Room design will consider features such as wall styles, window locations, doors, skirting boards and balustrades; the number of internal and external bends etc. • Construction materials include steel frame buildings, stud walling, brick and stone walling.
• Good cable protection • It allows for the use of tight buﬀered fibre pigtail cord solutions. Disadvantages include: • Less aesthetically pleasing. • More time consuming to install due to the need to cut the conduit to align with the building wall features.
• Aesthetics includes décor, colour schemes, furniture layout and skirting styles Conduit Conduit raceways are plastic channels that run along the edge of skirting boards, 5
Common Cable Requirements
Stapling is a system that uses cable saddle cleats to retain the cable to wall or skirting board.
• Fibre specification – in accordance with ITU-T G657.A2 or G657.B3 • Sheath material – Low Smoke Zero Halogen (LSZH) indoor grade material • Crush Resistance ≥ 800N
Advantages; • Lower profile than conduit; reduced to the height of the cable. • Less conspicuous than conduit. • Easier and faster to install. Disadvantages; • Requires a higher grade of fibre to manage the cable bends • Requires a more robust cable sheath to protect against damage when installing the cable saddles. • Cable saddles are less eﬀective in wall materials, so ideally should be aligned to the building studwork. • Stapling directly into brickwork is feasible; however not recommended as the cleats are much bigger and can cause damage to the wall. • Cable types are more expensive; however this can be oﬀset against the installation costs.
The three design styles, which are proposed are as follows: Easy Strip Flat Drop Indoor Optical Fibre Cable: This cable design is an existing product supplied by Sterlite. It is currently produced using G657.A1 and G657.A2 fibre. A G657.B3 variant is proposed for the in home requirements. The Sterlite variant is currently supplied in white; however other colours can be produced based on master batch volumes. Round Tight Buﬀered Optical Drop Cable: This is a new design for Sterlite and the current specification is based on G657.A2. A G657.B3 variant is proposed if used in building. Initial products will be produced in black; however other colours can be produced based on master batch volumes. Pre-terminated Fibre Cable using Ultra – Micro Cable
the additional features make it worthy of consideration. This product can be manufactured in a variety of colours.
Summary • It is possible to deliver fibre to the inhabited areas of a home. A robust cable is required to both protect the fibre and to minimise the risk of exposing fibre to the home owner if the fibre is in any way cut. (Note: a broken fibre will continue to transmit the laser light). • It is recommended to use a conduit cable cover, or a cable similar to the ultra-micro cable as it has very good material strength characteristics. • The cable must be low smoke and zero halogen to minimise inhalation in the event of a fire. • Aesthetic solutions can be provided, but non-standard colours such as brown will be dictated by volumes, due to the necessity to provide master batch material for the cable sheathing and therefore a level of standardisation in the buildings may be necessary. • Cable designs should ideally use G 6 5 7. B 3 fi b r e , b u t i n c e r t a i n i n s t a l l a t i o n s G 6 5 7. A 2 c a n b e considered.
Cabling in the home using cable saddles: While it is possible to bend fibre through 90º, the glass construction cannot tolerate sharp corners and therefore minimum bend radii (mbr) are applicable to each fibre type. Historically fibre management products have been designed to support conventional G652D fibre which has mbr of 30mm. The introduction of reduced bend sensitive fibre types has enabled the development of more compact fibre management products with mbr as small as 7.5mm. This includes the fibre cable itself.
The main advantage of this product is its high crush resistance. At 1500N, it oﬀers a very high level of protection for the fibres, whether installed inside conduit or stapled directly to building surfaces. The current solution is based on 3mm diameter with a 30mbr protective sheathing; however a 2mm version is under development. Whilst the radius is larger than conventional cable solutions,

Sterlite commissions next generation Carbon Composite Core conductor solution for Tata Power’s Mumbai project Upgrades the 22 kV IIT Powai-Saki transmission line crossing over a thickly populated slum area comprising of closely spaced hutments and hilly terrain – one of the toughest terrains for specialised stringing. One of the largest integrated power utilities in India, Tata Power provides reliable, clean and quality power. The company thus protects its distribution areas from sharp fluctuations and grid failures.
The Challenge Tata Power was contemplating on the need to increase the capacity of an existing 22 kV distribution line that delivers power to a number of industrial customers (Larsen & Toubro, Municipal Corporation of Greater Mumbai (MCGM), etc) as well as institutions of national importance (IIT, NITIE, etc). This, however, was a challenge, considering the fact that building a new transmission infrastructure in Mumbai has never been easy. Further, installation of a new transmission line would have been impossible, as the area was thicklypopulated and included a large number of hutments, that too along a hilly terrain. Hence, the company simply had to figure out a way of ramping up capacity without tampering with the existing infrastructure. 8
The Journey To increase the power transmission capacity, Tata Power considered several solutions such as GAP conductor, 3M and STACIR but none of them were found suitable for this particular project. The company also evaluated the following alternatives: • Underground power transmission: This would result in significantly higher cost (4 to 5 times higher) and greater operational limitations. • New Line: An additional D/C line would mean that the cost will increase by 4 to 5 times, as tower erection cost stands to be quite high. • Stringing: Stringing of HPC conductor was considered diﬃcult due to tough demographic conditions and hilly region. • Maintenance problem: Had Tata Power selected GAP conductor, the maintenance of line would have been very diﬃcult and almost impossible.
Besides, the utility was looking for a turnkey project partner who would oﬀer unique solutions… complete with installation, erection, commissioning and testing at site along with the supply of hardware and accessories.
The Solution The only solution for this was to replace the existing ACSR Dog conductor with an Carbon Composite Core conductor. Sterlite oﬀered a unique solution in the form of 28.8 km of this conductor to increase the capacity of its existing critical arterial 22 kV line distribution line that criss-crossed over several hutments as well as hilly terrain. Execution of this turnkey project for Tata Power included design, supply and installation of the carbon composite core conductors. “The lines on which Carbon Composite Core technology have been installed are very old lines traversing through populated areas,” says M V Deodhar, Assistant Engineer – Projects, Tata Power.
CLIENT FEATURE “The idea was to go for lightweight conductor so that we can retain our existing structures and augment the line capacity. Further, light weight conductor was mandatory in order to improve ground profile as well as maintain existing clearances. These three factors were under consideration while selecting the conductor,” Deodhar adds. Tata Power, thus, introduced Sterlite’s Carbon Composite Core with Trapezoidal Annealed wires technology to replace the old ACSR conductors with the vision to double the Power transmission capability over the same tower line and conditions. The complete re-conductoring exercise was supervised by Sterlite and carried out using specialised equipment like Tensioner and Pullers to eliminate any possibility of winding force between the carbon core and the trapezoidal annealed wire conductors manufactured at Sterlite’s Haridwar facility. Carbon Composite Core technology with fully annealed trapezoidal wire conductors are known to reduce line losses up to 40% compared to conventional conductors of the same diameter and weight owing to 28% more aluminium and better compactness which greatly increases capacity, reduces losses as well as providing cooler operating temperatures. The core is 25% stronger & 60% lighter compared to steel cores used in traditional conductors and have significantly lower coeﬃcient of thermal expansion which leads to less sag at higher temperatures. The technology already having established a robust footprint in excess of 20,000 km worldwide is patented by CTC Global, USA and is licensed to Sterlite Technologies. Further, these conductors have some inherent advantages. First, they can be laid over the existing transmission towers by just replacing the conductors in use. This obviates the need for acquiring SEPTEMBER 2013
additional land and building towers, to do which costs money and time. The same right of way (ROW) and towers of existing lines have been used, thus eliminating the need of acquiring new ROW, which is a very diﬃcult task in congested areas of Powai and Saki. By using Carbon Composite Core conductors on the 22 kV transmission line feeded between 220 KV substations at Saki, the stability has been increased mainly due to the trapezoidal shape of the conductor. “Until now the conductor has been loaded up to 480 Amperes and so far its performance has been satisfactory. We have been observing the performance/ behaviour of the conductor under faults, and so far the conductor is not subjected to fault condition,” aﬃrms Deodhar. The line would realise its promised throughput as soon as the substation upgradation gets completed. In India, re-conductoring is a technically and economically viable alternative, as transmission operators face increasing opposition while seeking new rights-ofway. The proposed Carbon Composite Core Conductor solution oﬀers conductivity and resistance to thermal sag, thereby allowing it to carry very high levels of current at higher operating temperatures during peak demand or emergency conditions. Completion of this installation is a vital step in moving forward with our utility customer engagements. It is important to illustrate our conductor’s ease of installation to customers as we prepare for commercial projects over the coming months," says K S Rao, COO – Telecom & Power Conductors, Sterlite Technologies Limited.
of the Transmission as well as SubTransmission Grids in India. Moreover, higher capacity, reduced sag and lighter weight also translate into lower project costs. These attributes provide economic advantages when upgrading an existing line with minimal structural modifications or installing a new line with fewer or shorter structures – definitely a vital step towards our utility customer engagements,” Rao adds.
Conclusion The conductivity of Carbon Composite Core conductor and its resistance to thermal sag allow it to carry very high levels of current at higher operating temperatures during peak demand or emergency conditions. Also, the transmission line loss of this conductor is 40% less compared to ACSR Dog conductor. Higher capacity, reduced sag and lighter weight also translate into lower project costs. These attributes provide economic advantages when upgrading an existing line with minimal structural modifications or installing a new line with fewer or shorter structures.
"We are confident of our solution backed by our application engineering strengths, Master Installer programs and flexible oﬀers customised to specific utility requirements will make significant contribution to the capacity and reliability 9
Fiber Optic Trends in the Communications Space Ludwig C. Graff
When considering where the fiber optic industry is heading we must look at the piece parts to fully understand the industry at large. To do this, it is important to break down the industry into the following segments: Fiber Optic Infrastructure; e.g. the last mile in fiber to the home deployments, Products and Applications. It is quite clear the trends toward using fiber optic deployments by Phone and Cable companies is where the lionâ€™s share of growth has come from in recent years and more than likely where it is going in the foreseeable future. The driving force is to have ubiquitous broadband, so the customer can have transparency no matter whether they are at home on the computer, in the car on their mobile device or at the oďŹƒce on a tablet type of device.
VIEWPOINT As you can see from the chart below the U.S. has been building millions of miles of fiber with the pace picking up since 2005. Much of this demand for fiber is in the consumer segment of the market driven by its insatiable appetite for more bandwidth to power the Internet, VideOn-Demand, Smart Phones and High Definition (HD) TV services. When you see consumer devices such as HD TVs at 1 inch thick and 50 inches wide, it is not hard to see why the service providers and cable companies want to provide the bandwidth to power these devices with advanced applications which lead to direct connection to the internet while unlocking the tremendous potential to all subscribers. There are significant requirements for inter-oﬃce and intra-oﬃce fiber outlay within the provider’s own infrastructure to provide these types of services. For years service providers and cable companies have been interconnecting their transmission hubs to provide optimum performance from their networks.
The chart below exemplifies the point that fiber infrastructure programs apply to both continental and inter-continental links needed drive the fiber backhaul. Building fiber optic networks from the ground up comes at a steep cost. The provider must consider manpower to perform the operation, products required to carry out the task and the capital required for the entire job. One carrier in the U.S. has been quoted at spending around $20B (USD) to reach about 18 million homes in 6 years. One of the benefits of such a large operation is some of the eﬃciencies that can be gained from experience to reduce the time it takes to pass a home with fiber. As you can see from the photo below operators have a pain staking operation digging up each customer’s yard/street for miles on end. So what are the lesions learned that drives eﬃcienciesnd cost eﬀective products. The goal here is to drive down costs by reducing installation time while working through a steep learning curve.
If we look at typical costs that go into fiber cable build we must examine the placement of the cable i.e. Ariel or Buried as being one of the most time consuming from a labor perspective. Whichever type is used there must be an interconnecting terminal in a central location. This point provides connection to the main feeder cable. It is important during the entire process to consider the cable count and types of cable to be used. There are many diﬀerent types of cable such as Loose tube, gel filled etc. When considering the bandwidth we should look at either single or multi mode cables. All of these factors can aﬀect costs and timelines. One of the eﬃciencies (learned from experience) was the development of pre-connectorized fiber cable from the terminal to the hub in the street and then from the hub to the Optical Network terminal at the customers residence. Days have been eliminated from the fiber cable installation by eliminating the laborious task of fusion splicing in the field.
VIEWPOINT Since all cables are tested in the factory for continuity and other characteristics, it also eliminates troubleshooting of cables once laid in the ground or the overhead poles thereby saving costly manpower. It has been said that “experience is the best teacher”.When it comes to providing FTTH products and applications this is especially true. Through the initial development of FTTH services we have seen numerous products evolve to meet specific applications. An excellent example is the evolution to the Optical Network Termination (ONT) unit. ONT devices are the final termination point of the fiber optic line placed at the customers’ premises. Initially they were located on the side of the home near the existing Network Interface Device(NID). Since the first ONT units rolled oﬀ the factory floor they have been developed many times over for specific applications such as: a garage unit for town house, a closet unit for inside the home, a desktop unit for multi-dwelling units MDUs. There are more than 20 of these types of devices in use in the field at this time serving the customer experience.
The MDU applications, typically large multi-story apartment buildings, have provided many challenges from an installation perspective as well. There were many questions that required new product designs, such as: where do all the Battery Back Up (BBU) units that will serve 100-200 apartments be placed? How do you deal with older buildings with narrow or non-existent risers for intra-building fiber drop cable? What do you do to place an ONT in an apartment without power in the desired closet where it will be placed? One of the more interesting challenges was in the form of esthetics. People who live in expensive high rise apartment buildings do not want to see fiber optic drop cable placed in the hallways between the riser closet and the apartment. Much thought, design, and cost went into creating raceways that were acceptable to the homeowners. In the end all these problems were resolved with creative and acceptable solutions. Everyone will admit that the great global recession of 2008 has taken its toll on all markets including fiber optics. But predictions are that the market for fiber optic components could reach record levels. Market research firm Global
Industry Analysts, Inc. (GIA) predicted in its “Fiber Optic Components: A Global Strategic Business Report” that the world fiber-optic components market will rebound from the economic downturn to become a $31.3 billion opportunity by the year 2015. Continued migration from copper to fiber networks in the post recession period and the need to oﬀer attractive service packages to capture large a number of subscribers will lead service providers continuing to invest heavily to replace the traditional last mile networks with an end-to-end fiber access network, GIA believes. This trend will translate into increased demand for fiberoptic components.” We have seen in emerging markets countries such as India that the fiber market is indeed booming. Sterlite Technologies Ltd. has announced a very aggressive fiber build out in several major cities in India. They are well on their way to achieving their goals there. We expect for this trend to continue for years to come.

Virtual Classroom Project
Sterlite believes that technology can change the education landscape of our country. Through ‘viable technology’ we aim to mitigate the eﬀects of unavailability of teachers as well as of their dismal quality. Keeping in mind the vision of reaching out to children and communities through technology, Sterlite Tech Foundation has started a pilot project in a few Municipal schools in Mumbai. The aim of the project is to improve the quality of learning of children through direct interaction with the children of these schools and build capacities of the in house teachers through Virtual Classrooms. An expert teacher from our foundation delivers a lecture from the studio through VSAT technology which is transmitted live to all the classrooms. The children at the other end have a large screen to observe the lecture, a webcam as well as a mike for interaction. The idea is to leverage the few excellent teachers to teach multiple classrooms. The learning environment is designed to be dynamic, where teachers can share videos, use smart boards for explanations and can interact with students. Since December 2012, Sterlite Tech Foundation has been delivering live sessions to 45 Municipal Corporation of Greater Mumbai (MCGM) classrooms in the upper primary section (5-7). Prior to the commencement of live sessions, we conducted a one-day orientation for all the Headmasters and teachers followed 14
by a 3-day teachers training. The objective of this training was to brief the teachers about their role as facilitators and reach out to students. The project reached out to 2000 students and 50 teachers of 25 MCGM classrooms in the pilot phase.
sessions in Math, Science and English through experts • To train teachers in virtual classroom facilitation skills that will help engage students in virtual classroom sessions and thereby enhance learning levels of students. • To monitor and assess the program continuously, thereby collecting indicators reflecting change in motivation and interest levels among teachers and students towards virtual classroom sessions.
Pilot Phase (Dec ember 2012- March 2013) This intervention aimed to create a sustainable large scale adoptive model to bring in positive change in the teachinglearning process in MCGM schools through a pilot initiative in eﬀective delivery of virtual classroom sessions in Math, Science and English to students of class 5 and class 6 of English and Marathi medium schools. The pilot was monitored and a ssessed continuously.
Expected Outcomes • Exposure of students and teachers to innovative teaching methodology • Improvement in facilitation skills of teachers.
Objectives • To support MCGM schools in delivering virtual classroom !
SUSTAINABLE DEVELOPMENT Training of Teachers in Fa c i l i t a t i o n o f V i r t u a l Classroom Sessions
observe. The trainers invited the class to come and perform the exercise. We had enthusiastic participants in the form of volunteers for this activity. • Mr.Arya , Beat Oﬃcer- MCGM visited the session to address the teachers as well as to resolve the issues and concerns that the teachers had with regards to implementation of VC, assuring them that he and his team members were accessible. For any other diﬃculties, Sterlite Tech Foundation’s on-field team would be able to guide them
A three-day training session was conducted for the teachers before the sessions were delivered from the studio . Objectives: • Understand the gaps in the current teaching-learning scenario and the need to fill these gaps in order to achieve better learning out comes • Identify common mistakes ‘teachers as facilitators’ may make to influence students’ participation in virtual classrooms. • Reach out to students, motivate them and create excitement in them to attend and accept delivery of lessons through virtual classrooms • Engage students in virtual classroom sessions and thereby enhance their learning levels.
• To give a proper closure to the lesson with reinforcement and maintain the level of interest in VC sessions in students throughout the intervention
The Mind Map Activity conducted via the Virtual Classroom was much appreciated. The live session enabled the teachers to gain a positive outlook towards the technology based teaching medium and were confident that the students would benefit from this facility.
Highlights: • As a prelude to the diﬀerent styles of learning (Visual/Audio/Kinesthetic) the trainers introduced “Surya Namaskar” . Instructions were given in Marathi and the class was asked to listen attentively. Subsequently the entire Surya Namaskar was demonstrated without saying a word, the class was asked to
Low Lights: • Hindrance due to technical issues • The teachers confided that with the kind of problems they currently face in handling kids from a poor socioeconomic background, VC would be additional work with technical problems etc. • Some teachers also voiced problems about infrastructure, manpower constraints as well as multi tasking (one of the male teachers actually said that they were teachers cum clerks, to which some others added that it was cum security, cum
• Facilitate the sessions and complement the eﬀorts of the virtual classroom teacher during the lesson delivery
Positives and personal observation from the trainers: “There was a remarkable change in attitude and perspective towards the VC concept as well as VC training; we (Karuna and Sayema) noticed a major shift in the mind sets of the teachers.” Day 1 to Day 3: The training was applauded and we received compliments galore as they found it very interactive, and mentioned that they had never had an experience such as this in any of their trainings before. The activity based training was highly appreciated. Implementation & Traction of the pilot: The pilot was planned for 3 months and it used the following three indicators to measure impact: Classroom observations: All the sessions were monitored by a team of people on a weekly basis. Head Master and Teacher interviews: Interviews were conducted with teachers and Headmasters at the end of the project. We collected their feedback about how the project made an impact in the learning level of students. Based on the success of the pilot, the team has scaled up an English and a Science program across 50 MCGM schools. The program is now currently reaching out to 3000 students and 75 teachers all across Mumbai
Team The team has experts from American school of Bombay, Teach for India Alumni, Akanksha Teachers and Teachers’ college, Columbia University. The team has experience of best international practices as well as hands on experience of working with local disadvantaged communities in India.
