摘要：
In view of the problem of the low efficiency in traditional classroom teaching due to the limitation in time and space, an exploration which combines real classroom with virtual classroom in hybrid learning was proposed. We chose the teaching of a software engineering course and used starC as the teaching support tool for analysis. In our study, the teaching process was divided into several teaching units, and each teaching unit was further divided into several activity units. The content was organized in the form of topicalities, where students are allowed to choose the learning content according to their study plans and preferences. Through the questionnaire survey which includes the indicators of participation and satisfaction among the students on both traditional learning and hybrid learning, it is found that the students on hybrid learning have higher participation and satisfaction than that on traditional learning. This indicated that hybrid learning could effectively improve teaching effectiveness.

摘要：
Using time of flight (ToF) measurements for positron emission tomography (PET) is an attractive avenue for increasing the signal to noise (SNR) ratio of PET images. However, achieving fast timing resolution required for high SNR gain using silicon photomultipliers (SiPM) requires many resource heavy high speed readout channels. A method of multiplexing many SiPM signals into a single electronic channel would greatly simplify ToF PET readout systems. In this work the effect of multiplexing on the timing resolution of analog SiPMs is modeled, simulated and tested. The simulations and experiments show that baseline fluctuations from cumulative uncorrelated dark noise are the most important cause of timing degradation, but their effects can be mitigated with baseline correction. A charge sharing network for position sensitive multiplexing is proposed and tested. Results show a full width at half maximum (FWHM) coincidence timing resolution of 232 +/- 2ps for single 3mm x 3mm x 20mm LYSO scintillation crystals with 16 SiPMs multiplexed to a single timing channel (in addition to 4 position channels). Measurements with a 4x4 array of 3mm x 3mm x 20mm LFS crystals show excellent crystal separation with a minimum ratio of distance between crystal peaks to standard deviation of crystal peaks of 11.9. The mean FWHM coincidence timing resolution of the 4x4 LFS array was 278 +/- 7ps. All experiments were performed at room temperature with no thermal regulation. These results show that fast timing resolution for ToF can be achieved with highly multiplexed analog readout.

摘要：
The organization of learning resources is an important part of an online learning system. However, the methods which we commonly use in recent years, such as organizing resources manually and single type resource bundle, cannot meet the requirements of online resources organization. We propose a micro-resources organization and generation method based on mixed resource bundle. This method contains three parts which can respectively realize the pack, analysis and layout of online learning resources. In this paper, we give the details of how these three parts are working. Then, we give an example of English micro-content resource bundle. It proves that our method can work very well in English online learning. In the next phase, we will extend our method to other subjects.

摘要：
Computer games have from early in their development, experienced negative attitudes from many quarters. Many of these attitudes arise from quite superficial views of computer games, though some work has also been done by those who have observed harm being done to understand the reasons for this and the context in which it occurs. Others have tried to use computer games in the treatment of a range of illnesses. While a wide range of work has been done there have been a number of obstacles to delivering therapeutic interventions. One major problem is the difficulty of developing the highly sophisticated games that are. This paper looks at how recent availability of tools which can support the creation of such games have made it potentially easier to produce them. Examples are given of how these are being used in supporting work that has been shown to be of value in treatment.

摘要：
Instant messaging (IM) software, widely used in the campus, are used in teaching by some teachers. Through the exploration of IM software, emerge a unique teaching form called the teaching based on Instant Messaging (IM) Software. But do we really know the characteristics of this teaching pattern? Are there any methods that let the teachers quickly review their own courses and improve the instructional design? The paper uses a video analysis method which base on behavior observation. The coding of the teaching and learning behavior was followed by a quantitative content analysis and a sequential analysis of behaviors. Social interaction in the IM software, and technology support behaviors were explored. Furthermore, we try to extract the key behaviors to verify the teaching design and help the teacher improvement his teaching.
摘要：
Educational game is a certain computer games that can develop the user's knowledge, skills, intelligence, emotion, attitude, values. Kinect can listen to the voice of the people and observe people's action through the skeleton tracking technology and speech recognition technology which make it easier to communicate with computer. By analyzing the the key technology of the existing education games, we can find that the application on Kinect is rarely. This paper makes full use of the advantages of Kinect and the characteristics of the education game to design a serious game model based on Kinect. The working principle of Kinect and the definition of serious game is introduced. A case according to the educational game model based on Kinect is implemented at last.

摘要：
Although the flipped class as an innovative way of teaching has been widely accepted, but the lack of practical case hinds its further development. Therefore, a three-dimensional flipped class design and the relevant empirical analysis is proposed, which takes "C language program design" into account. The task-driven, problem-queried and plus/minus score strategies are adopted to accelerate the process of the learners' knowledge construction. The questionnaire and final scores of students in Educational Technology Specialty are utilized to demonstrate the feasibility and effectiveness of the proposed approach. The results suggest that the proposed approach is beneficial to the theoretical and practical development of the flipped class.
摘要：
Adaptive learning requires the learning contents to be presented to students dynamically in a personalized fashion. Multiple displays on cross-platform devices can meet the diverse needs for content presentation. Current practices approach web page design for multi-terminal devices on a trial-and-error basis. This paper discusses a web page design method that uses the client resolution adaptive table for multi-terminal devices. To obtain the table, we calculate the character size and other elements for the best visual effect by adapting to the client's device resolution.

MOOCs;Recommender System;Undergraduate
摘要：
One of the challenges of MOOCs is to recommend appropriate courses to match individual characteristics of a special learner, although MOOCs are an excellent supplement of traditional higher education. Based on the effects of individual characteristics on learning, a novel framework is proposed for designing an undergraduate-oriented recommender system of MOOCs in which the particular characteristics of the participants, such as cognitive level, knowledge background, personal expectation, learning interest, learning motivation and learning style are emphasized. More specifically, the particular characteristics of undergraduates are introduced into the discussion of the recommendation methods including content-based recommendation and collaborative filtering recommendation. Meanwhile, the recommendation strategies and recommendation algorithms are analyzed in the discussion.

摘要：
Structured knowledge contains a wealth of information, it can effectively help learners to carry out the knowledge model and apply the knowledge flexibly. There are many ways to express the structured knowledge, ontology is one of them. Ontology clearly express the contents of domain knowledge and relationships between knowledge points. Structured knowledge is often used in computer processing, few of people are able to use these resources to promote their study. They often don't know from where and how to start their study when they face the complex structured knowledge. To improve the problem, this paper introduce the idea of algorithm to help learners learn structured knowledge. It will make the learning of structured knowledge more certain operability. Finally, it designs a learning process of structured knowledge and summarize some elements for learning structured knowledge.

摘要：
The purpose of this study was to investigate the effects of interactive whiteboard (IWB)-based instruction on students' learning achievement. A quasi-experiment study was conducted using a sample of 93 students from two 10th grade classes in a secondary school in central China. While students in one class employed the IWB-based instructional approach, students in the other class employed the traditional lecture-based instructional approach. Students in both classes studied English for three months. Students' first-and second-tests showed that the students with the IWB-based instructional approach had a better learning achievement in English than did the students' with the lecture-based instruction approach, which indicated that the use of IWB can improve student learning when cooperated with an appropriate instructional approach.

摘要：
The task of recording source identification is to extract digital evidence of device mechanism involved in the generation of the speech signals by analyzing the acoustic signals. This paper proposes a Device Universal Background Model (DEV-UBM) based algorithm for identifying recording devices. When extracting the features of recording devices, the mute voice is extracted from the input speech, and then MFCCs extracted from the mute voice after pre-processing are as the features of recording devices. DEV-UBM is used to represent the model of recording device, and log-likelihood is used to describe the final scores, which are used to classify different recording devices. The experimental result indicates that the mean accuracy of recording device identification on 9 recording devices is 93.16%, which shows the proposed algorithm is effective.
摘要：
In this paper we introduce an approach for automatic recognition and reconstruction of building facade structure from oblique aerial images. Contrast to street-view image oblique aerial image has larger field of view but lower resolution, weaker texture and more noise. To overcome these shortcomings, our approach firstly analyses the horizontal distribution density to extract individual facade area from image. Then a hierarchical repetition detection method is employed to partition the facade and recognize structural elements. Finally, the geometry structure of each facade element is reconstructed jointly by all repetitive image tiles. Results show the potentials of the proposed approach.
