There are many peple who don’t understand deeply and clearly about the nature of motivation, evenly sometimes they are misunderstanding about it. Motivation is difficult to define because it is central to language learning, complex and challengung for teachers to deal with. Motivation is the combination of effort plus desire to achieve the goal of learning the language plus favorite attitudes toward learning the language (Gardner, 1985, p.10). To say in a simple way, motivation is the purpose or psychological cause of an action.
The effort is an acheivement. An example of that would be: Clayton has been recognized for all his efforts this year. In other word, effort means to exert to do something by all your ability. Clearly, you must spend alots of time to do it, always use your head to think about this.
The desire to achieve the goal of learning the language means you must determine avowedly the pupose of learning the language and try your best to obtain the goal which you propsed.
The favorite attitudes toward learning the language, I think it is not difficult for you to understand. Before learning something, I think you must love much. If you love, you will spend much time for it. If you love, you have enough effort to do it. And if you love, you try the best to obtain the goal. Thus, the attitude is very important to get the best result.
In short, although motivation is very difficult to define clearly, it is not too dificult to understand. Basing on define of each part; I think you can be easy to determine your attitude, the goal and your effort when you have intention of learning the language. Good luck to you!
