However, any schools need focue only on salient factors, it implies that even simple optimizing decisions may not always be made. So, with a better understanding of student individual fun learning environment and fun teaching method learning need and fun courses teaching learning contents, subjects choices etc. these factors will possible bring knowledg to design more effective learning policies and improve student individual learning outcomes.Moreover, improving student learning attitude factor is also important to raise whose learning interest. For example, by reading motivational passages or watching tagic movies which can encourage students to focus on positive identifies related to learning and intellectual curiosity may be one approach a growing evidence suggests that many students and parents are not fully informed about education costs, future economic and non-economic related benefits and options. It is possible related to whose low-income family backgrounds and poor learning attitude both factors. So, if the family was one high income family, it will have possible to influence whose sons or daughts to build good learning attitude. When they have good learning attitude and good family growing relatonship . Theb, they will raise learning interest, due to they had built from good learning attitude when they are living in one good family relationship environment. In special, when the family is one low income family and low educational level background, parents will beed to work, so they will neglect to teach whose sons or daughters to know whether they ought how to learn easily, which wil be one correct or right learning attitude to learn by themselves successfully. They will neglect and lack useful educational recommendation to compare education cost, future economic and non-economic eduational benefits and learning attitude and opinion methods and the suitable courses and teaching books contents opinions to let whose their sons and/or daughters to know how to learn effectively by themselves, instead of school teaching method. So, these students' parents' lacking useful learning recommendation or negligent education learning recommendaton behaviors which will also cause the low income family students to build " discouraged hard learning attitude" to let them to raise interest to learn any more new knowledge persuasively. Even, due to the non-educational behavioral opinion of pre-school decision making opinion, if the parents discovered that the school is one suitable school to let their sons and/or daughters to learn persuasively or attratively in order to let they can earn good examination resultsor pass subjects more easily. Then, these disappointed parents and low grade examination result of students will feel need to learn more hardly if they are still not improving theire grade when they feel that they had been studying hardly in the school. Consequently, it will bring more negative learning emotion to the students and families. Hence, disappointing or poor or negative learning attidude or emotion to the student's feeling, this factor must not raise the student individual interest to learn in the school. Otherwise, positive or good learning emotion or attitude will influcence the student to raise learning interest to continue to learn in the school consequently. hence, schools ought not neglect to improve students to build positive learning emotion or attitude habitually in order to raise whose interest to learn in the school more easily.
