This paper analyzes the existing ideological and political construction mode of vocational education curriculum, based on the constructivism theory, according to the curriculum objectives, closely following the cognitive law and the characteristics of vocational activities, reconstructs the curriculum modularly, constructs the dual channels of ability advancement and quality improvement, forms a curriculum ideological and political design idea of collaborative education, and designs the curriculum as a whole. According to the requirements of all-round and whole-process education, this paper explores the implementation path of ideological and political education, and carries out ideological and political practice teaching through the interactive curriculum co-construction of three teachers, online and offline resource coverage, and professional quality integration assessment. According to the "student-centered" teaching strategy, combined with the specific cases of the course, the design and implementation were verified. The results showed that students professional identity and professional quality were significantly improved, and their awareness of combining morality with technology was significantly enhanced, thus achieving the goal of curriculum education and improving the ability of curriculum education. Through exploration, the education mode of "big country project leading, three teachers cooperating and five self-educating" has been formed, which has improved the ideological and political construction ideas and specific implementation paths, and has practical reference and popularization value for ideological and political construction of engineering majors.展开更多

The peak eclogite facies (P > 1.40—1.50 GPa, T = 680—730℃) mineral assemblage is composed of garnet, ompha-cite and rutile (±quartz), which was overprinted by the granulite facies mineral assemblage of vermicular symplec-tite of sodic clinopyroxene and plagioclase which replaced the precursory omphacite, and then amphibolite facies ret-rograded minerals with characterization of Amp+Pl ke-lyphitic rim and symplectite, and amphibole replaced clino-pyroxene. The protolith of retrograded eclogites is oceanic basalt formed at 438±11 Ma.The peak eclogite facies meta-morphic age of the retrograded eclogite is 325±4 Ma. These relict eclogites may be formed by the subduction of Pa-leo-Asian oceanic crust beneath the North China Craton during Late Paleozoic. The discovery of relict eclogite in this paper provides a new insight into farther understanding of tectonic evolution of the northern margin of the North China Craton, and the relationship between the Paleo-Asian Ocean and the North China Craton.展开更多
