    The flipped class model is applied to the teaching process of carbon group elements, which fully reflects the effective teaching of "student-oriented and teacher-led". The students complete the "learning first" according to their self-study task list before class. The class's QQ group, wechat group and other social softwares communicate and interact with teachers and students online, and the cloud class topic database is used to detect the feedback effect of learning first. In class, teachers collect the feedback information of students' "learning first", carefully design the teaching process of "fixed teaching" problem inquiry, and encourage students to participate actively. After class, teachers and students can further communicate and interact online. Students can conduct self-awareness, self-reflection, self-evaluation and self-regulation of the learned knowledge unit, complete knowledge construction and improve students' metacognitive ability.

    Increased propensity of consumers directly visiting the e-commerce website is the most prominent effect of display advertising. Therefore, understanding consumers’ directed revisit behaviors is important for advertisers to arrange their advertising delivering activity. In this paper, authors used an e-commerce website’s consumers browsing data and advertising clicking data to examine the relationship between consumers’ previous shopping behaviors and their direct revisit. Besides, they also consider the visit channels (i.e., direct visit, generic advertising, and retargeting advertising). The results show that for consumers entering the website through different channels, their previous behaviors have different effect on the probability of revising directly in the future. The findings extend previous direct visit studies and can help website to advertise

    AbstractDam, not only has great ability to alleviate water shortages especially during the dry season which improve hydropower capacity, but also plays an imporant rule in the river ecosystem. Dam has significant effect in improving our water environment and protecting ecological system.This paper copes with the three-dimensional model of dams and discusses OpenGL modeling, lighting, material, model transformation, perspective transformation technologies to achieve visualization of the dam, and eventually we visualize the dam through concrete examples

    INFORMATION SYSTEMS RESEARCH IN CHINESE UNIVERSITIES: AN EXAMINATION OF THE INPUT SIDE

    Get PDF
    Along with the rapid growth of the Chinese economy over the past decades, information systems (IS) research in China has undergone a profound transformation. This exploratory study reports on a survey involving 107 university researchers, focusing on the input aspects of IS research and how institutional factors affect the input. In this paper, input mainly refers to research activities, effort, methods and reference disciplines. Data show researchers are withdrawing from IS development projects, while increasing their effort in academic research. Compared to the past, IS research topics are now more aligned to the international mainstream. A major hurdle for empirical research is the lack of familiarities with empirical research methodology, as indicated by nearly half of the respondents. Effort in academic research tends to correlate with the researchers\u27 income scheme, i.e., sources and proportion of base salary and benefits in their overall income. However, surprisingly, emphasis on quality of publication has not significantly influenced researchers\u27 effort yet, nor has the increased degree of internationalization affected the selection of research methods and the shift to empirical research. The underlying reasons are explored, and implications are also discussed
