摘要：
With the advancement and deepening of education information work, online collective lesson preparation has gradually become an important way to promote teachers' professional development, and effectively promotes the creation, sharing and utilization of teachers' knowledge. This paper adopts the method of literature research and based on the SECI model to construct the model of teachers' knowledge transformation in online collective lesson preparation, moreover, this paper also deeply analyzes the cyclic transformation process of teachers' knowledge between individuals and organizations with concrete examples. The results show that the members of the online collective lesson preparation community are independent and related to each other, on the one hand, members share knowledge through online communication of teaching ideas, teaching methods and teaching experience, and then put them together into a holistic organization of knowledge to transform tacit knowledge into explicit knowledge; on the other hand, teachers internalize the new explicit knowledge into tacit knowledge through practice and reflection, and promote their own professional development in the continuous iteration and update of knowledge.

摘要：
Crowdfunding and crowdsourcing in digital education service has become an important content in educational informatization. Different personalized demands from learners for digital education service are increasing day by day, which leads to the asymmetry between supply and demand. This paper aims to solve the asymmetry of supply and demand in education sector under the SISC ecology model based on value chain theory, and also to elaborate the ecology environment in digital education service, as well as the subject and content of crowdfunding and crowdsourcing. Block chain is the protection mechanism for the rights of subject, which improves the development of personalized education. Empirical study and qualitative analysis are used to fulfill the effectiveness of SISC ecology model of CFCS in DES. A case of "Parallel" successfully recommends 10 resources that suitable for the students, which proves the feasibility of the SISC ecology model so as to improve the motivations of CFCS subjects and student' satisfaction. This paper also supports future research by developing a framework for crowdfunding and crowdsourcing in digital education service.
摘要：
Although the accuracy of handwritten character recognition based on deep networks has been shown to be superior to that of the traditional method, the use of an overly deep network significantly increases time consumption during parameter training. For this reason, this paper took the training time and recognition accuracy into consideration and proposed a novel handwritten character recognition algorithm with newly designed network structure, which is based on an extended nonlinear kernel residual network. This network is a non-extremely deep network, and its main design is as follows:(1) Design of an unsupervised apriori algorithm for intra-class clustering, making the subsequent network training more pertinent; (2) presentation of an intermediate convolution model with a pre-processed width level of 2;(3) presentation of a composite residual structure that designs a multi-level quick link; and (4) addition of a Dropout layer after the parameter optimization. The algorithm shows superior results on MNIST and SVHN dataset, which are two character benchmark recognition datasets, and achieves better recognition accuracy and higher recognition efficiency than other deep structures with the same number of layers.
摘要：
Based upon the self-regulated learning theory, this study examined the relationships between academic achievement and three key self-regulatory constructs - prior domain knowledge, self-efficacy, and the use of learning strategies - in two flipped undergraduate math courses. Structural equation modeling was employed as the primary method to analyze the relationships in both the pre-class and in-class learning environments of the flipped courses. The results of the study showed that students' self-efficacy in learning math and the use of help seeking strategies were all significantly positively related with academic achievement in both pre- and in-class learning environments. In addition, students' self-efficacy in collaborative learning had a positive impact on their use of help seeking strategies during in-class learning. The theoretical and instructional implications are discussed.

摘要：
This paper presents an algorithm for understanding problems from circuit schematics in exercise problems in physics at secondary school. This paper models the problem understanding as a problem of extracting a set of relations that can be used to solve problems with enough information. The challenges lie in not only analyzing the circuit schematics but also extracting the proper relations for a given exercise problem. To face these challenges a novel approach is proposed to detect circuit nodes with their current flows to extract the current equations for nodes. And the other novel approach is proposed to extract voltage equations of independent loops. The proposed approach was tested with a dataset collected from the text books and the exam papers for the students at secondary schools. Experimental results show that the effect of recognition and analysis we designed delivers promising result, and our approach can be adapted to more complex electrical circuit analysis.

摘要：
With the development of Internet technology, telemedicine technology has become one of the hottest research topics. In this paper, a Web-based medical image viewer application is presented in order to facilitate timely and accurate diagnoses in a telemedicine system. The application can access the remote medical image database and display image over the network. This application implements the basic functions of the two-dimensional image processing. Besides, 3D functions, e.g, volume rendering and surface rendering of region of interest, fly through, can be also implemented by the proposed viewer. Medical staff can perform some basic operations via the mouse to make more effective diagnosis. Experimental results show that the basic image processing functions and advanced 3D functions can be achieved by this application and it presents a high level of usability, functionality and performance.

摘要：
This research started with the topic of educational technology of Zhihu. In order to explore other hot topics associated with it and the hotspots and trends in the parent topics of the annual questions, this research used the method of co-word analysis, social network analysis. Through digging topics network structure to understand the relationship between topics topics location and roles in the network. This research found that there were two major hot topics under educational technology topic. One was a hot spot of other professional topics closely linked to educational technology. The second was hot topics of interest to users under this topic. Through social network analysis, it was found that the structure of high-frequency topics network was relatively close and the structure of the parent topics network was loose, forming a higher tendency of centripetalism with educational technology as the core, and the topic with the core position in the network also had strong intermediary. The hotspot for future parent topics will be those at the edge of the high-frequency parent topics network, but in line with the current research hotspots in the field of educational technology.
