According to Wikipedia, " Blended learning is a formal education program in which a student learns at least in part through delivery of content and instruction via digital and online media with some element of student control over time, place, path, or pace ." These models of learning is used by both job market and academia. There are various models such as flex, Rotation, Self-Blend, enriched virtual model, la carte model etc. Three major models are discussed below. Flex Model In this model most of the instructions are online.Teachers provide assistance in-person only if there is need of assistance.The schedule of classes is decided by students and face-to-face interaction is minimal in this model. Rotation Model In this model mode of instructions (online & onsite) are rotated on a routine basis. This rotation schedule is generally decided by teachers. Students mostly learn at traditional schools with brick and mortar structure. Self-Blend Model In this model students th...

This is a branch of economics which deals with economic concerns of education policy. It starts with the basic demand for education and financing of education but it is not limited to that framework. A lot of work has been done including Becker's Human Capital theory, Screening Hypothesis, Job market signalling , capability approach, social choice approach etc. Some economists have also worked on below mentioned topics: Education and economic growth(Endogenous growth theory) Education as a public good Financing of public education Returns to education Economic assessment of training schemes Measuring productivity and Input out analysis Market failure in education In my opinion, a lot of work is still needs to done in this field. some of the topics of future research could be "Economics of technology enabled education", "Finance of PPP in education" etc.

I am just posting  my experience of participating in StatWars- An event conducted by Department of Business Economics, University of Delhi in its annual flagship event Vishleshan. (Eventually, I ended up winning the event). As this event was related to predictive analytics, those who do not have much Idea of predictive analysis can refer to my past post  How can you learn Predictive Modelling? Introduction to StatWars In this event we were asked to predict whether the residents of the city will purchase the one time investment scheme or not. The full problem description is here . My Methodology Before explaining the methodology, I assume you have some idea of four algorithms namely logistic regression, random forest, decision tree and knn. I used an ensemble of these four data mining algorithms. There are two ways of understanding my code 1. Read Individual codes and then read Ensemble.R (Which might take longer but this is better way) 2. Just read the Ensemble.R and forg...

Let us start with the introduction of predictive analytics. Before Knowing what it is and how it suits us, it is worthless to learn that skill. What is Predictive Analytics? According to SAS ,"Predictive analytics is the use of data, statistical algorithms and machine-learning techniques to identify the likelihood of future outcomes based on historical data." Other definitions are just one click away from you .Just google it.  that is why google has become a verb from a noun :) Why Predictive Analytics? As stated earlier, this is one of the most important question to be answered first. (the only exception is that if you have passion to learn new things in life, you can skip this and start learning) Predictive Analytics is a part of Data Science(It's a subset of Data Science) and we all know that Data Science is the sexiest job of 21st century. you can refer that Oct 2012 HBR article  here . A lot of other sources such as   Forbes,  Inc,  Adobe  have al...

Indian Education system has many severe problems. They can be categorized under four heads : Quality,Quantity, Financing and Others. Quality Poor Rankings of Indian Institutes Quality of teachers Students don't have skill-sets required by industry Old Curriculum Poor quality of primary education  Quantity Low literacy rate Increasing demand of education as the population is increasing(education accessibility) limited seats in Universities Financing Lack of Infrastructure  Short Supply of Educators Salary structure of teachers Others Indian education system promotes Rat Race Lack of ambition(risk taking ability) for entrepreneurship in students Lack of proper career  counselling  Rote Learning Note: In rest of the blog, I will try to write about the solutions to above problems. Edit #1: (March 03,2017)   I found a beautiful question on quora. I wasamazed to see so many answers to this question. Some of the answers are really good. https://www.quora.com/What...

    The motivation for writing this article is Fort Minor’s song “ Remember the name ”. Is there any composition of attributes /skills/qualities that are required to become successful? If we assume that if people remember your name, it means you are successful, then according to that song they have said following compositions will work fine: “Ten percent luck, Twenty percent skill, Fifteen percent concentrated power of will, five percent pleasure, fifty percent pain, and a hundred percent reason to remember the name” Do you agree with those compositions? Or do you have a different composition according to you? Anyways, let us forget about the song and we should focus on our main discussion that what is the recipe of being successful. Even if we want to make a cup of tea, which is considered to be the simplest item to be cooked after the ban on Maggi in India, we need to have a proper mix of ingredients of tea. Similarly is there any recipe for being successful?...
