How to Integrate Learning Assessment and Student Analytics in Every Day Education  By Gumbi Software Private Limited, Bangalore In traditional schooling, delivery of education often tends to be teacher centered - with children expected to remain passive and only listen. Since students at different learning levels sit in the same class, it becomes extremely difficult for teachers to provide targeted instruction to students. The fact is student engagement begins and ends at raised hands, questions asked, or simply maintaining eye contact. Over the years this has been resulting in only selected students being interactive in the class and most students remaining inactive throughout the academic year.

The small pilot plant, which uses solar energy to heat the water for desalination. ( Source : The New York Times) Introduction Chennai has a population of 7 million and every year it faces an acute water shortage crisis. (Willem Hofste, Reig, and Schleifer 2019). As defined by the UN Water initiative, a country is classified as ‘water stressed’ and ‘water scarce’ if water availability goes below 1700 m3 per person and 1000m3 per person, respectively. India currently scores at 1453 m3 per capita water availability. The Minjur and Nemmeli desalination plants were setup to counteract this precise status of India and ease the demand burden on the Chennai metropolitan. Currently, both plants supply 100 million litres a day (MLD) but at exorbitant operational costs. The global situation of water is an observable feature of climate change and a huge question mark. Population growth, over-extraction, climate-induced water stress, and pollution are all reasons responsible for the loss of fresh...

Introduction  One must take as given that today our goals, lifestyle choices, opinions and aspirations are influenced by western ideas of what a good life constitutes. The past two decades in modern world history have shown how there exists a McDonaldisation of world imagination, a 1 homogenization of thought, where the American dream isn’t limited to those who exist within that paradigm but stretches across borders and cultures. McDonaldisation On its own, the term development lacks any precise definition. Despite this, it is firmly seated in popular and intellectual perception. It is inherently linked to the words which form it - growth, evolution, maturation. The idea of development holds for each individual a different connotation. These varied conceptions arise from the socio-political and economic context of individuals with the underlying sentiment always being to reach a better place than yesterday, to move from where one is, and to reach a space that one envisions as bette...
