Leveraging Power of Big Data In Education

What is Big Data?/Brief Intro To Big Data

Big Data

Big data refers to the large amounts of data(Data sets) that are generated which cannot be analyzed using traditional methods. This data is mostly unstructured and is usually of unknown value. This data is collected and analyzed using computing so as to make sense of it.

Big data is emphasized by three Vs: volume, velocity, and variety. Volume refers to the amount of data, depending on the organization this can range from terabytes to petabytes. Velocity refers to the fast rate at which data is received and processed, for most big data applications the data is usually store in memory first rather than on hard disks due to their slow read/write nature. Variety is the final V of big data and it refers to the variety of data that is now available. Unlike in the times before where data was structured and could be stored in relational databases, data generated nowadays is highly unstructured.

In order to understand big data, we need to understand how much data there currently is. According to a study done by University of Southern Carolina (http://www.sciencemag.org/content/early/2011/02/09/science.1200970.abstract), as at 2007 there was an estimated 295 billion gigabytes of data (295 exabytes). This can be eclipsed in the near future given the amount of data generated daily stands at 2.5 Quintillion bytes(https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=WRL12345USEN) and given that the number of internet users as at the of 2017 stood at 3.2 Billion, this number can change dramatically.


How Does Education Fit In With Big Data?

Given the amounts of data generated one would expect that some significant progress can be made in the world in different sectors. The education sector also stands to gain a lot by harnessing the power of Big Data. By using these vast amounts of data, institutions can initiate programmes whose success would be virtually assured.

Before this data can be used, these institutions need to collect it first. The systems for such collection is already widely available since institutions keep a lot of data regarding students from performance to financials. By optimizing this data collection and expanding the collection into other areas, it can be easy to create a picture of a student that will help the institution understand how to offer the best service.

Institutions can use big data to tailor learning experiences to individual students instead of using a blanket approach to teaching which leaves some students disadvantaged. A student can have their own study of the curriculum customized to fit their  own understanding thereby ensuring that every students get the value of understanding.

Effects on the workforce, of using big data in education

Understanding how different students learn, can help an institution set up systems that optimize on their resources eliminating what is essentially blind investments into education experiences.This type of optimization can lead to more investments into areas such as Research.

Tailored education experiences can also help produce a workforce that is ready for the market once they finish their studies since students can be taught in order to be ready for a sector that they feel they’ll best best into. Companies in the US for example used about $164.2 Billion for training and development in 2012 (http://www.astd.org/Professional-Resources/State-Of-The-Industry-Report?_ga=2.49638438.1206958595.1526541678-1963358284.1526541678), this number can be reduced greatly by having graduates that are already prepared for the market by using big data.



Nairobi Tech Hackathon

Adopt- a-seedling

Nairobi Tech Week (NTW) was a great opportunity for me to interact with amazing Tech enthusiasts and developers from all across the city and beyond. I was mostly involved in the hackathon though I did attend a couple of talks such as the Microsoft Azure tech talk. The hackathon was the most memorable part of NTW for me. We worked on building projects from the ground up. This was to be done in  time span of only 24 hours. Different problems in line with specific technologies were posted to us and we were to pick one and work on it with the specified technology to which it was attached.

AngelHack were the proud sponsors of the event, giving us, the participants a back story on how the competition works and how it all started. We also learnt about the awards we would get based on the problems we would choose to solve. I was in an all-girls group named ALGALRITHM. We are young girls with ambition and the will to put in the work needed to make our country more tech friendly.

Christina, the main organizer from Angel Hack

The project we worked on and eventually built a prototype on for, is called Adopt-A-Seedling. It is a web app that enables its users to plant a seedling from the comfort of their own homes or workplaces. Our target audience is individuals and companies looking to put in money to save the environment but lack connections to effectively ensure that their money is actually put to the right use.

Once on the application, a user can purchase as many seedlings as they would like through Visa direct and get a notification that their seedling has been reserved for planting in a specific location in their country through a messenger bot. They could also choose whether  or not to receive a notification once their seedling has been planted or not.

The experience was quite the learning experience, having to push one’s mind and body into completing a working project prototype in 24 hours. We won the hackathon and got amazing prizes along with it. I would highly recommend participating in hackathons for any junior or middle-level developer looking to gain exposure in coding.

Traits that make a great technopreneur

The technology scene in Africa is on the rise with Nairobi being one of the cities at the forefront of technological advancement. There are so many tech enthusiasts interested in turning their idea into  a business. Almost everyone with sufficient knowledge in software development wants to be a techpreneur. A technopreneur or techpreneur is an entrepreneur who gets a technology idea and finds an opportunity to make it a commercial reality. There are several characteristics that make a good techpreneur.

Recently at a panel discussion that was held at Moringa School various key players in the tech industry gave their insights on what it takes to make a good techpreneur. These are the major areas that they focused on when talking about their experiences both as techpreneurs and investors:

1. Understand your customer and then build around that. Creating an amazing customer experience differentiates you from your competitors.- Sam Gikandi, CEO at Africa’s Talking

2. The only way your business can compete effectively with others in the market is through execution. Several people have similar businesses but what makes you stand out is how you execute your idea.-Irene Hu, a Principal at Open Capital Advisors (OCA)

3. Quality, timeliness and consistency are critical for your business. Always keep commitment to your clients for your business to grow.- Caine Wanjau, CTO at Twiga Foods.

4. When you are starting a company it is important to bootstrap for as long you can. The earlier an investor gives you funding the more control they have over your business. -Irene Hu, a Principal at Open Capital Advisors

5.You need to identify what stage your company is before approaching an investor. If you are at seed stage you need a lot of mentorship- Yacob Berhane, Head of Growth and Investment at mSurvey

6. Before creating a product it is important to look at the problem creatively and finding a solution. Technology should be used to scale up the business once you have already identified how to solve a problem. – Caine Wanjau, CTO at Twiga Foods

7. It is important for a founder to be able to sell the vision of a start up to the team.-Muraya Kamau – Managing Director at Devient Limited

8.  Having the right skills and the right team around you is very important for an entrepreneur. Investors look at the strength of a team when valuating your business. – Irene Hu, a Principal at Open Capital Advisor

No great achievement in life is possible without persistence. A great techpreneur will stay positive because the odds will always be against taking the first leap of faith. Persistence in techpreneurship means sticking to the mission regardless of long or hard the road seems.

A Day in the Life of a Programmer

By Moringa Core 7 Graduating class

Becoming a good developer takes so much more than learning how to write good code. Here is what the graduating class had to say about their experience at Moringa.

Programming was always an abstract concept for me during my campus years. However this changed after an introductory course to programming which drove me to look for the best way to learn programming. Moringa school came in highly recommended by friends. During the Immersive course I was able to fall in love with problem solving as it gave me satisfaction to find solutions, regardless of how trivial the problem was. The course was project based; one learns through building applications. This allows one to grow the self-learning skills, and this was a highlight for me – a platform to allow me to learn how to learn and not just reproduce information. – Joshua Kodhe


From the time I was in campus I have always been interested in programming but my degree involved majoring in both statistics and computer science. I thus could not focus on my programming fully and that made me believe that programming was hard. After campus I read a book on  growth mindset and that revived my passion and the mindset towards programming. That drove me into learning Ruby on rails on my own for 4 months. After a few months of not getting far with my skills, I decided to join Moringa School.The past six months I have been in Moringa school have taught me that with the right mindset you can achieve anything. By building applications that have helped solve various problems, I am now more than ever able to view problems not as threats but as opportunities for growth. -June Muoti

When I started out in Moringa School I had some basic knowledge in coding however, just a few weeks in Moringa taught me that there is so much more in programming than I thought. The skill that I value most of all from Moringa school is the ability to adapt and learn new technologies as well as how to debug my applications.I would therefore recommend Moringa School to both beginners and those familiar with coding techniques.- Seth Muriuki


My journey through Moringa has been something different. Definitely not what I’m or most people are used to. Its been challenging at the same exciting. When you learn to grow around people with the same beliefs and motivations as you, you get to have a different perspective on things.That’s what Moringa has helped me achieve. It’s no walk in the park, but its really accomplishing and you become self-aware about what you want.- Andrew Kimani


Qualities of a Good Programmer

Article By,

The tech ecosystem in Kenya is rapidly growing and the number of students who consider taking a career in software development after high school has greatly increased. As much as technical expertise is important there are a lot of factors that employers look out for when searching for new tech talent in their companies. A candidate with quick learning ability, leadership skills and great attitude is what most tech companies are looking for.

There is a popular belief that you need to have a background in computer science for you to be good at programming. Doing computer science gives you a better understanding of computer architecture and gives you a better understanding of the world of programming but you should also have the ability to self learn. Read a lot of articles on the latest technologies and tech blogs. There are also numerous online resources that can help you get better at your skill.

Team work is one of the most important skills that a good programmer should posses. There a few coding boot camps across the globe that use a collaborative learning model. Here in Africa we have Moringa School a top coding accelerator where you are able to sharpen your programming skills through pair programming. This is working in pairs on a project. This prepares you for the real work environment where you will be required to work as a team to solve a problem.

Current Moringa School students working on their final projects

A good programmer will always develop systems with the user in mind. It is not enough to learn programming concepts. Your main focus should be to make an app or website that is solving a real world problem.  Industry leaders like airbnb,uber, amazon and netflix are redefining the standards for customer experience. A great programmer wants to know whether the features they’re building has high value to the customer.

Lastly it is important for programmers to have great time management and task management skills. This will enable you to estimate how much time it takes to complete a task and know how to deliver projects to clients on time. Always under promise and over deliver when you are working on projects to gain credibility.

Living a Life

Whatever a mind can conceive and believe,it can achieve’, I frankly don’t know who said this words, but they are true. It is believed that we only use 10% of our brain’s potential during the course of  “our” lives ( I dispute this). But to those who don’t, what about the remaining 90%? Why don’t they use it? What stops them from using it? The simple answer is “Themselves!”

When we were born in our early years, we had no limits:We did things without fear or inhibitions. With our innate knowledge, we tried discovering new things. But some people grow and forget how sweet it was to try new things as a baby, without any fear of failure.

Very few people know how powerful the mind is. It is the greatest tool somebody can possess. And children really know how to try using the tool in many things, some that are considered insane. But somehow, there are people who really seize the opportunity and make massive use of their mind.

Majority of those who make “massive” use of their mind have made great creations, have invented and designed things that have changed the world. Others have made their lives happier and have had more fun. Think of Campayo Ramon,who can memorize 17 numbers in half a second; Ki Peek,who knew every zip-code in the USA, and the crazy Chao Lu who memorized 67890 digits of pi with 100% accuracy. These all are all to do with memory, but it shows some of the things we are capable of.

It’s only a week since I was introduced to serious coding and I feel like it’s the greatest thing that ever happened since sliced bread, something that compels you to think ‘without a box’.channeling energy towards creativity, adventure and fun. It makes use of the inactive brain potential that some people are afraid of putting into use. You work without fear, without any inhibitions, but with an open mind that reflects the power of art;Creativity; in human life.

It is at Moringa School that we’ve decided to rediscover fun that we had as kids, trying out new ideas with confidence. Seizing opportunities to create solutions. And having no excuse to limitations that have bound others. We are not just learning at Moringa School, we are living a BIG LIFE!
