Secondly, the cumulative geoid height errors are 1.727 × 10^-1 m, 1.839 × 10^-1 m and 9.025 × 10^ -2 m at degrees 70,120 and 250 from the implemented three-stage satellite gravity missions consisting of CHAMP, GRACE and GOCE, which preferably accord with those from the existing earth gravity field models involving EIGEN-CHAMP03S, EICEN-GRACE02S and GO_CONS GCF 2 DIR R1. The cumulative geoid height error is 6.847 × 10 ^-2 m at degree 250 from the future GRACE Follow-On mission. Finally, the complementarity among the four-stage satellite gravity missions including CHAMP, GRACE, GOCE and GRACE Follow-On is demonstrated contrastively.展开更多

It uncovers for each teacher a conceptual framework for practice, which comprises teaching principles and strategic intentions. It reveals that teachers＇ frameworks for practice are an interwoven system of their most strongly held beliefs in language teaching and their perceptions of their teaching contexts, and that teachers＇ own learning and teaching experiences are important influences on their conceptualisations of classroom work. Findings of this research have implications for language teacher education and development.展开更多

Even though they hear about language-culture teaching theory and practice in the classroom, they are lack of confidence in trying to introduce a cultural dimension. The purpose of the article is to discuss how to integrate the theory of English teaching in intercultural dimension with its practical application in the classroom and to what extent the in-service teacher training course designed for middle school English teachers in Xinjiang can contribute to promoting their acquisition of intercultural communicative competence. The innovation requires changes in teachers' self-concept, in their professional qualifications, in their attitudes and skills towards English learning and teaching. Some activities for the course are presented and some ideas may serve suggesting approaches to teacher training.展开更多
