Resume The critical role of energy storage is by now self evident they are indispensable for an increased share of renewable energy and electric vehicles. Considering the abundance of sodium resources, sodium ion batteries NIBs are poised as an alternative to Li ion batteries as sustainable electrochemical energy storage EES solution. However, several technical challenges still remain to be addressed before the commercialization of NIBs, with the anode being one of them. Graphite has been employed as the anode for commercial lithium ion batteries LIBs since 1. However, for NIB, a high degree of disorder of the carbon structure is needed to allow sodium insertion at positive voltages. Therefore, alternative anode materials are demanded. One family of candidates is nongraphitic carbon, which comes in the forms of HC or soft carbon SC. For both SC and HC the amount of sodium ions that can be inserted at positive voltages between the graphene layers is greatly increased compared to graphite. The specificity of HC is to present an additional capacity traduced by a low voltage plateau LVP. Since the pioneer work of Stevens and Dahn in the early 2. V and the low voltage plateau are usually ascribed to defect assisted intercalation and packing of sodium within the voids opened between cross linked graphitic layers, respectively, 9 although recent results demonstrate that it might be more complicated than that. Due to this extra capacity due to the LVP, the effort of the community has been mainly focused in recent years on hard carbons and on improving their capacities by tuning their micro porosity.

Thus, there is tremendous need to understand deeply the sodium insertionextraction mechanism into disordered carbons. In the present work an optimized PVC based SC as active material for NIB negative electrode will be underlined. A comparative study of the performance of PVC C compared to Sugar HC with similar particle size and electrode preparation will be presented. Although it does not present the typical low voltage plateau of hard carbons, PVC SC reaches an initial reversible capacity of 2. Ahg and retains 2. Ahg after 1. 50 cycles at 2. Ag. At high current density of 1. C 3. 72m. Ag, the electrode still can achieve a capacity of 1. Ahg with a Coulombic efficiency near 1. The microstructure and the morphology of these carbons have been studied by coupling gas adsorption, powder X ray diffraction in situ and ex situ PXRD and Small Angle X ray Scattering SAXS measurements, which, by correlating with their electrochemical performance, had led us to identify the and identifying key microstructural features at origin of the performance of PVC SC and give new insights into the mechanism of sodium insertion into disordered soft and hard carbons.

Because of this tremendous increase in the numbers of Asian, Hispanic, and other linguistically and culturally different individuals, school districts can no longer ignore the need for adjusting instructional programs to better serve these groups. One result has been a great expansion of bilingual education to provide for the educational needs of students with limited proficiency in English. To better understand programming needs, some clarification of terms is necessaryclarification that can lead to far more effective instructional methods. What is the Distinction Between Bilingualism Versus Bilingual Education Demographic variables show evidence that there will be an expansion of groups eligible for services through bilingual education. However, bilingual education often means different things to different people. In order to understand the basic concepts of bilingual instruction, certain terms need clarification. The terms bilingualism and bilingual education appear frequently in literature. However, there is a great deal of variation with regard to the meaning of these two terms Hakuta 1. An individual who can speak two languages is usually considered bilingual. However, confusion ensues when the degree of proficiency enters into the discussion. Some authorities claim that a bilingual person must have native like fluency in both languages Bloomfield 1. Others maintain that minimal competency in two languages is sufficient to be called bilingual Haugen 1. Diebold 1. 96. 1. Hornby 1. 97. 7 gives the following advice in hopes of resolving this issue bilingualism is not all or none, rather it is an individual characteristic that may exist to varying degrees from minimum ability to complete fluency in more than one language. Bilingual education is another term requiring clarification because of its variation of meaning in different circles. The following is a commonly accepted definition of bilingual education Bilingual education is the use of two languages as media of instruction for a child or a group of children in part or all of the school curriculum Cohen 1. It is also acknowledged that it is impossible to totally separate language and culture. Consequently, the term bilingual education includes the concept of bicultural education Ovando and Collier 1. The U. S. Congress in P. L. 9. 5 5. 61, which is known as the Bilingual Act, defines the term program of bilingual education as follows A program of instruction, designed for children of limited English proficiency in elementary or secondary schools, in which, with respect to the years of study to which the program is applicable. English, and, to the extent necessary to allow a child to achieve competence in the English language, the native language of the child of limited English proficiency, and such instruction is given with appreciation for the cultural heritage of such children, and of other children in American society, and with respect to elementary and secondary school instruction, such instruction shall, to the extent necessary, be in all courses or subjects of study which will allow a child to progress effectively through the educational system. The basic definition of bilingual education generally agreed upon by both scholars and laypersons, is the use of two languages as media of instruction. In other words, there is agreement regarding what the process of bilingual education is, but confusion arises when the philosophy and goals of bilingual education are discussed. Appendix B provides a checklist for effective bilingual programs. What Are the Goals of Bilingual Education Bilingual education can be organized into the following four categories cognitive development, affective development, linguistic growth, and cultural enrichment. Blanco 1. 97. 7 notes that the consensus of experts in the field of bilingual education is that its primary goals are in the area of cognitive and affective development rather than linguistic and cultural realms. From this, one could surmise that the primary goal of bilingual education is not necessarily to teach English or a second language, but to teach children concepts, knowledge, and skills through the language they know best and reinforce this information through the second language. Anderson and Boyer 1. Bilingual education is a new way of conceiving the entire range of education especially for the non English child just entering school. Bilingual learning necessitates rethinking the entire curriculum in terms of a childs best instruments for learning, of his readiness for learning various subjects, and his own identity and potential for growth and development. Although bilingual education experts feel that cognitive and affective development should be at the core of the bilingual program, not everyone recognizes these as the primary goals. It is not uncommon to have people feel that the linguistic goals should be primary The main purpose of the bilingual program is to teach English as soon as possible and integrate the children into the mainstream of education or to place emphasis on cultural goals The main purpose of the program should be to maintain the native language and culture while the children learn English. By placing emphasis on the linguistic and cultural side of bilingual education, confusion and controversy often arise. Although transition to the mainstream and maintenance of the native culture are both important, neither should be the central theme of the bilingual program. A bilingual program with a transitional linguistic and cultural goal is one that uses the native language and culture of the student only to the extent necessary for the child to acquire English and thus function in the regular school curriculum. This program does not stress the childs native language L1 and thus, does not teach the student to read or write in the native language. English language acquisition is also emphasized in a bilingual program with linguistic and cultural maintenance, but also promoted is the value of linguistic and cultural diversity. Children are encouraged to become literate in their native language and to develop bilingual skills throughout their schooling even into their adult lives. This transitional approach to bilingual education is supported by state and federal legislation however, many districts go beyond the law and use local resources to implement maintenance programs for language minority students. What Are the Underlying Principles of Second Language Acquisition Second language acquisition L2 is developmental, continuous, interactive with cognition, and rule governed. It is acquired by the student through interaction with the environment. The affective variables include motivation, environment, attitude, and socioeconomic status. It would seem to parallel primary language L1 acquisition with one major exception the child is not usually a participant of the L2 target language group and as such is at a distinct disadvantage. The L2s ability and inclination to interact with the L2 group is vital for learning the language. Principles. The student is an active party in acquiring language. Languages are acquired, not taught there is little adult teaching in learning a language. No matter what we do it is the learner who determines whether or not the language is gained. Students construct their own rules in language acquisition. Language proceeds from the general to the specific.
