i am not sure about my grammar..?

Learning means that “a long-term change in mental representations or associations due to experience” (Ormrod, 2006, p18). We have learnt many things since we are children. Learning does not just involve learning in school, but we can learn at home, at shop, and through communication with other people. The learning help us to create or receive knowledge and help us to understand what are around us such as, human being, space, oceans and the lands. Leaning includes memory what helps us to remember what we learnt. Memory means that “learners’ ability to “save” things mentally” (Ormrod, 2006, p24). it is the place where can keep our knowledge for a long time. Each human has three types of memory which plays role in learning process. They are the sensory register, working memory and long term memory. Each of these has own job. Short-term memory is a model of memory where information does not stay for a long time. Learning mostly uses or works in a short term memory because there is a lot of information which the student learns or receives either in text book or during class. For example: in last semester, I studied the dates of War World II, but now I do not remember all of them because the dates were saved in working memory. In contrast, long term memory reserves information in our mind for a long time, but it is not necessary to remain it forever. There are steps to save information in our mind for a long time in learning. For example, my strategy in studying is effective when I rehearsal or use the information in drawing or playing games.
