Threshold energy is the energy level where some chemical/physical action happens. For instance water boils at 100 deg C the water molecule attains enough (kinetic) energy it can escape from the rest of the pull of the water molecules. It can be used other context as well e.g. there enough electrostatic energy build up in the clouds, a lightning occur. This is the threshold energy.
How field of education is affected by the capabilities of computer?
Computers are becoming more and more important within education both as a learning tool and as a teaching tool. It is also very much useful for keeping records of all individuals at the school.

What is the link between theory and research?

Why can no machine or device convert all the energy available to it into useful work?
Not quite true ... I give you the electric heater.
All the power in comes out as heat.
The problem with everything else is that there is always losses due to friction and/or hysteresis that becomes heat - lost heat because it is not the desired output.

What animals use insight learning?
have no idea
might be monkeys?
Monkeys do use insight learning, especially when they are using "tools" like twigs to fit small holes in trees to collect insects for food. They can chew the twig down to fit the hole and it requires little to no trial and error. Also ravens have been known to use insight learning when gathering food. There is a great example of a raven using insight learning to pull up a string that has food at the end. the raven had no prior knowledge of how but manages to loop the string unti the food is in reach.What criteria they use in evaluating their school curriculum?
One of the most common ways to evaluate a school curriculum is through student testing. Educators and administrators will look to see if student improve or decline in areas of study. If the majority of students show a marked improvement in areas such as math or reading based on test results, then a new school curriculum will be deemed as effective.
The lecture method is a teaching method, in fact the teaching method most often found in universities today. It bases itself upon the transmissive teaching model, in brief terms that knowledge is an object that can be transferred from the teacher to the learner.
Practically it implies a lecturer holding a lecture for a group of people. A strength is that it is possible to educate large number of people at once, thereby lowering costs. A limitation is that it yields less deep knowledge compared to other teaching methods such as case-based learning. (Chaplin 2009, White et al. 2009, Grunwald & Hartman 2010).

Advantages and disadvantages of a questionnaire?
There are both good and bad reasons about using questionnaires as they are cost effective as they are only paper, they are easy to analyse as they can be easily completed with computers that may have a coding system, questionnaires are also very familiar to people as almost every one has completed or looked at one, they also are less intrusive than telephone or face-to-face interviews in which people may feel pressured to answer a question differently because of peer pressure whereas questionnaires are anonymous.
There are two different types of questions that should be used in a questionnaire. There are open questions which give the person answering it a chance to tell us their opinions and reasons and these questions provide qualitative data which is hard to analyse as there are no two answers that will be exactly the same, and there are closed questions which give a multiple choice answer, these type of questions provide quantitative data which is easy to analyse, but these closed questions do not allow the person answering to give in-depth insight and reason behind the choice.

What are the positive effect of being a student?
Someone once said that the day you stop learning is the day that you die. You are a student of everyday life. If you touch something hot, then you learned not to touch certain things. A student in a school can learn specific topics. Most of what students learn in school are things that someone else learned the hard way, (Ouch! Don't touch hot things.") Learning about your country is easier as a student because you can't travel all over it and gather all that there is to learn. Many others have done that for you. You can learn in a controlled atmosphere where outside intrusions won't distract you. A person who is a student will go far in life. I also heard that someone said, " Those who fail to learn from history are doomed to repeat it." or something like that. Have a blessed day.
