Speaking is a Skill

Learning the aspects of a foreign language might be easy for some students.  ,but However, being able to speak by using them in it for real life situations might may be difficult for the others. For example, one of the students could be smart in knowing how and when to is adept in use of the English tenses in English, but when it comes to speaking, he/she might fail to deliver not even one sentence was spoken correctly. in English. As Thornburg (2005) states that knowing a language and being able to speak it are not the same.,similar Therefore, knowing several skills or sub skills such as, grammatical rules, a list of vocabulary or how to writing a short paragraph perfectly is not enough when it comes to speaking. completely different if it is compared with speaking skill. In addition, Bygate (1987) makes an analogy between knowing how to drive a car theoretically  knowledge and skill on one hand and actually driving it a car on the other hand. If someone Knowing the parts of the car, the names of some controls is only good when speaking to a car mechanic about the problems the car may have.  It has nothing to do with driving. their places and how to use them does not mean that he will be able to drive the car unless he has some practice and experience in driving.

Similarly, in speaking, Knowledge is needed along with and skill are handmaidens to speak effectively. [This sentence proves what you are trying to say.  You need the vocabulary (knowledge) and how to express it (skill) to write or speak well.] However, according to my experience, in most schools in Libya what teachers teach is merely the impart the knowledge but not the skill. This idea has been supported by Abu Ghararah, '' "speaking talking is generally discouraged in schools and classrooms. Speech Talking in class is used only when learners limited to those students who are called upon to repeat or answer a question.'' Abu Ghararah (1998, p.33).

Learning and teaching speaking how to speak well is might be a challenge for both students and teachers. Speaking skills is are seen as the most difficult skill among the other skills of language aspect as compared to for instance, reading, listening and writing.

Agreed with most what you are writing.  However, I believed that if you can write well, you speak well and vice versa  (though you may pronounuce the words wrongly or speaking in a accent.  However, these can be corrected easily to a certain extent.)  Even if you can speak well, you still need special classes to articulate well.  For example, in public speaking.  You need to learn a whole different set of rules, tips in delivering your communication to others.  Communication skill is the most important in learning a language.  So what if you speak and write in perfect Latin or some dead language.
