And add text clues to the panoramic video in a timely manner to test the impact of the text clue design on the learning effect of the panoramic video for college students. Participants were college students (39, 10 males, 29 females, age range 20-22 years old). Students in the experimental group watched a panoramic video on AIDS prevention with text clues, while students in the control group watched without text A panoramic video of clues about AIDS prevention. This study conducted pre-test and post-test on the students in the experimental group and the control group. The results showed that the academic performance of the experimental group and the control group were significantly different.
摘要：
Cognition and emotion in online collaboration play an important role in achieving high-quality collaboration performance. Especially in the online synchronous collaborative environment, the limited time and place require higher language instantaneity and flexibility of thinking, which brings great challenges to students' high cognitive behavior and emotional experience. However, few empirical studies have focused on the cognition and emotion of students in online synchronous collaboration. Therefore, a quasi-experimental study was conducted based on a creative synchronous collaboration task to explore the effects, social knowledge construction and emotional experience of Multi-Input and One-Output(MIOO) collaboration and Multi-Input and Multi-Output(MIMO) collaboration. The findings indicated that the MIMO collaboration groups performed better than the MIOO collaboration groups in creative achievements, but were more affected by technology. Besides, the MIOO collaboration groups had a higher degree of social knowledge construction and more positive emotional experiences.

In order to further improve the effect of cooperative learning and promote the discussion and interaction among group members, this paper designs and verifies a grouping strategy. This strategy elicits empathy ability on the basis of homogeneity among groups and heterogeneity within groups. The influence of empathy on cooperative learning is studied. Forty-six fourth grade students who participated in science courses are selected as the research objects. The learner with high empathy ability is chosen as the group leader in the experimental group, while the learner with low empathy ability is chosen as the group leader in the control group. At the same time, statistical analysis and social network analysis method are used to explore the influence of empathy on learning effects and group interaction. It is found that the group of high empathy ability is significantly higher than the group of low empathy ability in group discussion interaction density and learning effect. This also provides a reference to the later development of learners and the future development of cooperative learning.
摘要：
In recent years, online education service platform has swept the world due to its high quality, openness and variety of education resource, and user registered in online platform has increased dramatically. However, the traditional centralized information storage method based on the third-party may cause problems such as the loss and disclosure of the transaction subject identity data, seriously threatening the legitimate rights and interests of users. Therefore, based on education service theory, this paper applies blockchain technology to identity authentication to design and implement a blockchain-based digital education transaction subject identity authentication system. The system proposed in this study can store identity information in ciphertext form and is jointly verified and maintained by the entire network node, thus it can guarantee the security and reliability of identity data in the digital identity authentication.
摘要：
Wireless Multimedia Sensor Networks (WMSNs) are increasingly penetrating into all areas of human life and activity. According to forecasts of leading experts in the field of telecommunications, sensor networks as a component of Internet of Things (IoT) in the medium term will take an important place among communication networks. QoS routing protocols for WMSN have been a growing topic of research for many years. In this paper we present a new approach called M-EIGRP (Modified-Enhanced Interior Gateway Routing Protocol) with load balancing. This modification of the routing protocol is offered for low losses in the WMSN backbone infrastructure. The new protocol also offers a new flexible, multi-limited objective function that can integrate multiple metrics, including delay, load traffic and bandwidth to determine the end-to-end path.
摘要：
In recent days, the wireless communication technology has become an integral part of several types of communication devices as it allows users to communicate even from remote areas. Wi-Fi is one of the main types of wireless communication used by many electronic devices such as laptops, smart phones and Internet of Things (IoT) devices. Using Wi-Fi infrastructure to provide quality multimedia services and deploying IoT services requires new approaches to network resource management. The method of adaptive size formation of a Wi-Fi network cell in the corporate infrastructure is proposed. The idea of the method is to adapt the size of a Wi-Fi cell coverage depending on the QoS requirements and load localization under conditions of insufficient bandwidth resources for network users and IoT devices. This method is implemented by writing a script file on the Cisco 5508 Wi-Fi controller that makes informed decisions on changing the cell coverage size in a centralized manner. Using this method allowed to provide high-speed wireless Internet access for users, provide a good QoS for IoT services and increase Wi-Fi network availability in high network-load conditions by effectively managing network resources depending on the actual operation scenario and requirements of individual users and IoT devices.
摘要：
The paper presents the research and comparative analysis of the bandwidth of low-power wireless IoT devices as wireless switches.

To get temperature indicators sufficiently built into Python libraries to read temperature files. The paper focuses on the synchronicity of measurement results records for more accurate analysis. As a result, the dependence of the measured factors was calculated using the Pearson correlation formula. These measurement factors affect the autonomy and energy consumption, which is important for IoT devices, and therefore, among the devices tested, recommendations were made regarding their choice when used depending on the conditions.
摘要：
The evaluation of MOOCs (massive open online courses) is needed to improve their design quality and to inform learners regarding course selection. In this paper, we proposed and validated an Analytic Hierarchy Process (AHP) Approach based on standardized rubric, expert feedback, data mining and emotion detection to systematically and diagnostically evaluate the quality of MOOCs. Using this approach, we analyzed review comments of three popular MOOCs on the Coursera Platform. The results indicate that the AHP approach is a feasible MOOC evaluation method that can provide accurate ratings as well as in-depth analysis of course design and learning outcomes. It is concluded that this new approach can supplement the existing user rating system with automated formative and summative evaluations.

摘要：
An energy-conserving protocol of routing is critical to a wireless sensor network (WSN) because of limited energy supply and communication capabilities of wireless sensor nodes. LEACH protocol has been widely used, which is based on a homogeneous network without considering most heterogeneous sensor networks in practical application. In addition, instantly sending data perceived by sensor nodes to the cluster head is not suitable for specific applications such as anti-submarine underwater, in this kind of application environment, most of the sensing data is redundant. Therefore, this paper proposes an improved clustering protocol with data transmission status switchable, which can be used in heterogeneous sensor networks. Cluster heads filter the perceived information and start data transmission link, and then send data to the sink when the information intensity perceived exceeds the preset threshold. Otherwise, cluster heads record the received data and continue receiving data sent by the next round of cluster nodes. We fortunately found in the simulation results that the network lifetime is prolonged several times than the protocol of LEACH.

摘要：
The short text in the online learning community is an important source of data in learning analysis. Therefore, the quality of the short text has a significant impact on the study of learning analysis. Due to the large amount of text data in the learning community, manual detection and repair will cost too much. This paper proposes a text detection and repair framework based on an online learning community. It aims to automatically detect and repair various types of semantic errors and grammatical errors that exist in online learning community short texts. The framework utilizes existing text error detection and repair algorithms and integrates them effectively to form a comprehensive detection and repair algorithm. In this paper, the validity of the framework is verified through experiments on the constructed data set. The experimental results show that the framework has high accuracy in automatically detecting and repairing text errors. (C) 2019 The Authors. Published by Elsevier Ltd.
摘要：
This paper reports on a pilot investigation on an Online Flipped Classroom Learning Model (OFCLM). It was designed for a class of open and distance education for adult students taking a modern educational technology course at a learning center. Unlike FCLM, The OFCLM made use of network live broadcast and multi-screens synchronous interaction technology instead of the face-to-face classroom to realize an online flipping classroom. The study focused on the perceptions and experiences the students in regard to the design and implementation of the OFCLM. The main findings indicated that the students liked the flexibility and convenience of the online flipped classroom learning model. The study found that paying attention to the online students' discussion, a teaching assistant, group cooperation, the participation of online adult students, the redesign of instructional activities like online in-class flipped teaching mode, and the quality of audio were critical to the effectiveness of the OFCLM. It is found that adult learners' higher-order know ledge construction was improved through online discussion and group activity.

摘要：
Scaffolding teaching method is a learner-centered teaching method based on constructivism, aiming at cultivating students' problem-solving ability and autonomous learning ability. Lots of researches have studied scaffolding concerning subjects of biology and engineering, what lacks from such researches is the scaffolding designed in English teaching, especially in the support of information technology. In particular, information technology - based scaffolding is also scarce in the foreign language teaching. In order to bridge the gap, this paper introduced the results of a case study in which the students of primary school participate in the making of animation learning resources in English subject by using an animation production tool. Findings suggest that the student participants' perform better after participating in the process of making the situated animation resources. And most importantly, the resources they designed are intended to be reused and restored by facilitating the management and sharing. The article concludes with a discussion of the implications of the findings for improving the performance of students. It gives a new thought for the scaffolding from the perspective of students and provides them scaffolding learning experience thus improving learning motivation and cognition.

the delivery course;Students' perceived presence;relevant factors
摘要：
The delivery course enables students in rural schools in China to enjoy high-quality education resources as well as urban students. As in online learning, there is a lack of students' perceived presence in the delivery course. In this study, six teachers and their students in the delivery course were surveyed, interviewed and observed to explore the relevant factors that influence the students' perceived presence. The results showed that there was a significant positive correlation between the students' perceived presence and the teacher's experience, and a significant negative correlation with the grade. When the class size was between 10 and 20, the students' perceived presence was the highest. The students' perceived presence had no significant correlation with the students' gender and discipline. Based on the data of interviews and observations, this study also summarized three strategies to develop students' perceived presence.

摘要：
Rural small schools in China have characteristics including remote location, small scale and poor conditions in infrastructure, quality of teaching and teacher. The shortage of teacher resources is the biggest problem in rural small schools compared with other resources. To address the problem and help offer sufficient and high-quality courses in rural small schools, the sharing of high-quality teacher resources are the most significant way to achieve it. In this paper, synchronous interactive hybrid classroom and synchronous interactive special delivery classroom teaching are put forward to facilitate the sharing of high-quality teacher resources in experimental areas. This article introduces a case of practicing the sharing of high-quality teacher resources by information technology from the urban school to the rural school in Xian’an district, Hubei province. The article concludes with a discussion of the findings for sharing teacher resources to provide equal educational opportunities between urban and rural areas.
