I want to learn many new things, but cannot able to do most of all due to lack of time and inability of brain, I suppose.
As for example, many uses of Microsoft Excel are very interesting. But even after learning their use, I forget those within a month. It may be due to my age, I do not know.
Naturally, as much as we learn more, we feel that we need to learn more . I only want to learn, which part of educational technology is unnecessary, and too much to learn, from global internet era.
