Massive Open Online Course: Virtual Learning Environment
Technology has changed our lifestyle in all aspect: education, entertainment, business and others.In past, education assumed to be prospered on only in the presence of teacher and student inside a small cottage called GURUKUL. It was believed that the direct supervision of GURU is very necessary to impart good education over the children/student. Now the time has been changed. People are advocating towards a teacher-less class i.e virtual class. Online course is making it possible.Massive online course is getting popular day by day due to two main reasons.
PC: Wikipedia
Firstly, These courses are provided online and don't have any time constraint to attend class on the web. Whenever there is a free time, candidate can log in to course and complete the lectures, assignments and other activities. It provides greater flexibility to study hours to peoples who are busy in their work and can't attend regular lecture class on campus.
Secondly, These course cost very less or sometime comes free of cost and many people can participate on course at a time. During the course, one don't need to spend any money on purchasing books, copy and pay the college fees. It is sufficient to pay small amount of money per course to get a verified copy of certificate after completion of course. Massive amount of people can take part in online course as they all are operated through the web. It don't need to set up class room, arrange bench-desk and pay for furniture etc. Simply one can connect to internet which is very chap now days and can access his/her favorite course online.
The only demerits of MOOC is that one can't feel the lecturer as vivid as it happens between student and teacher in class room.
In summary, it can be concluded that massive open online course are very helpful to the people who have no time to go for lecturer class in campus but want to broaden their horizon of knowledge.

Will job Exit in Future: at the end of this century
Human beings are doing their work since beginning of ecosystem. Human, being an intelligent creature, has innovated various technology to assist/support its daily life activities. Form the uncivilized history to this modern history, technological advancement has achieved a peak. Now, there is a risk of replacing every activities of human beings by a machine. Everything is in the pipeline of automation. Then the question is obvious that will some jobs for human exits in near future or all job will be taken by machine? The rapid progress in technology has placed this questions to near the reality.
we can see so many machine around us which are doing something useful for us. For instance, if we go to bank, we can deposit cash on smart machine and withdraw cash form the same machine. The machine will automate the task of cashier, so the bank now don't need any cashier for the purpose of only depositing money and withdrawing money. It can't be denied that one day, the whole banking process will get automatized and they will not need any human for banking jobs. If the technology will developed int this respect, sooner then later we will loss our jobs and becomes jobless.
Automation in every field such as education, banking, industry and other field has increased productivity. Now the business house can make more profit with less human resource because most of the jobs are carried out by robots, for example, robots are being used in industry for the purpose of packaging, moving product form one place to other place etc. But the situation is just opposite if we consider it in case of job creation.
In conclusion, we can state that the use of technology is necessary in this modern age but we should be careful about its effects on employment and economy of the nation. It is much crucial for the populated nation such as china, India and Nepal because they have a heavy workforce which is in need of job.

Let's phase out the Pen and Paper Exam: To evaluate ourself
Examinations are used as tools to evaluate learning output in any kind of training or educational academy. We have been in these systems for many years. Now it is right time to make a debate on this issue whether we are assessing student's skill or learning ability accurately using pen and paper type exams?.

The traditional exam has certain advantages. They have the same question to all candidates so it is easy to make equal standard to all candidates. It is also considered more fair then other kind of exam because it provides a clear cut boundary between exam taker and examiner. For example, in our country, the examination conducted by public service commission has good faith form all people. Every one believe that these examination are fair and no one can make favor to any candidate. This is the strong point that many people advocate that formal method of examination are important to evaluate candidate. In addition, these examination can access the different ability of candidate such as reasoning, understating and critical thinking using different types of questions such as mathematical questions, multiple choice questions and essay type questions.
On the other hand, we can see many demerits on these kind of examinations. It is obvious that one can't measure's someone's ability within a period of three or four hours written examination. Many students couldn't perform well in such exams because of anxiety even though they have good skill and ability.
So, It is very important to take serious steps during the design of test materials whenever possible. Some time test designers only focus on specific area and miss to evaluate overall performance of candidates. For example, Sometime candidate get passed in some examination but fail to perform well in their duty. It is all because of lacking in evaluation criteria set during examination design.
In conclusion, we can't totally escape from the traditional pen and paper examination but can make it more scientific using modern tools and technologies. Other assessment techniques such as presentation, debate competition and writing assignment can be used ti measure the specific ability in a candidate in addition to traditional examination. For example, writing assignment can be designed to measure the independent learning ability and project competition to assess the ability of team work capability.
