At present, the majority classrooms of university teachers take 'classroom, teacher and computer' as center, using blackboard and projection to impart knowledge. It is a common phenomenon for teachers just to read out loud from computers to give lessons with the lack of paying close attention to individual differences and effective study. It is necessary to achieve a 'concept reconstruction' of classroom for the future talents cultivation and teaching reform. The future classroom should include contextuality, openness, intelligence, interactivity and cloud five characteristics, should have five functions which are pan-network and seamless access, multi-screen display and facilitate cooperation, classroom record and conducive to selfstudy, virtual & reality combination and resources expansion, intelligent control and people-oriented to achieve the design concept of classroom.

E-learning has gradually become an important learning modality in modern society. How to present the suitable and high-quality learning resource to students from massive learning resources is particularly important. Personalized recommendation technology is one of the effective solutions. However, because of the lack of consideration of learning context information, the existing learning resource recommendation methods cannot effectively solve the problems such as knowledge navigation loss and learning topic drift. In order to solve these problems, this paper proposes an e-learning resource recommendation method based on learning contexts. By constructing the learners' learning context map and "knowledge-resource" context correlation model, combining with the personalized recommendation technology, the learners are treated with learning resources that fit their learning goals, knowledge ability and individual preference. This strategy can help learners to grasp the knowledge system and learning direction, and improve their learning efficiency.

The purpose of this study is to determine conditions for sufficiently utilizing various services provided in Japanese learning commons. In this study, five good practices utilized by Information and Communication Technology (ICT) devices and provided as services in learning commons were chosen. The survey was carried out through the observation of the five learning commons and semi-structured interviews that were guided by those items and conducted by the person in charge of the learning commons. The results suggest that there are five conditions that allow for various services in learning commons to be sufficiently utilized: (1) Providing useful services to all students, (2) Providing services that the whole university needs, (3) Making students' use of the learning commons convenient, (4) Including entertainment space, and (5) Providing greater incentives for students. These conditions could make students extrinsically and intrinsically motivated to study and learn.

Rapid expansion of open educational resources and rise of massive open online courses, flipped classroom and other educational models and platforms have put forward new demands on teaching knowledge of micro-course coaching teachers. It has been found that technological pedagogical knowledge (TPK) has the most significant influence on TPACK structure of pre-service teachers (Zhang, 2015). This study explores technological pedagogical knowledge (TPK) structures of pre-service teachers who participated in competitions of micro-courses for Flipped Classroom on C20 platform. Based on existing video analysis system, this paper develops a micro-courses teaching encoding system. By combining quantitative and qualitative analysis and adopting comparative analysis, it explores pre-service teacher's TPK structures and characteristics in micro-courses from four aspects: teaching links, prospective students' cognition level, teaching medias and TPK.

With the development of Internet and technology, educational information development has entered into the situation—" deep-water zone ". As a powerful means to promote the development of educational information, educational information service has attracted the attention of researchers. Based on the literature research and questionnaire of educational information enterprise, we conduct an investigation on the current operation situation of educational information enterprise, the type and mode of educational information consulting service, product satisfaction, application effect and challenges. The study found that the types of educational information consulting services mainly focused on teaching reform, basic environmental construction, teaching evaluation, ability training of applying information technology, but weak in the capability certification and IT strategic consulting. And the service satisfaction is positively related to the response speed of the enterprise to the customer demand. There are four aspects about difficulties and challenges in the development of educational information enterprise—weak advisory service concept, the lack of reference standards, talent bottlenecks and inadequate leadership support. Especially the lack of reference standards and talent bottlenecks are the current urgent challenge which educational information consulting services industry need to overcome.

We have developed Personalized Education and Learning Support System (PELS) [1], which has been formed by motion model theory of a rehabilitation robot HAL (hybrid assistive limb) [2] for general purposes in Education. By using this system, we have supported for instructors and learners to make the best use of individual traits for collaborative learning in group work. In this paper, we will introduce the concept of the PELS structure and the results of the examination in practical nursing class. PELS is consisted by a main controller, feedforward control and two kinds of feedback control. Firstly, we will gather various kinds of data and analyze them after Big Data processing (Main controller) so that we can find patterns of learners' behavior (Feedforward Control). Next, instructors will be informed those results of Big Data analysis (Feedback Control) and consulted by supporters to optimize grouping and teaming in which learners will be able to communicate interactively with each other. Lastly, through those interactive communication smoothly, learners might become aware of their own learning methods in collaborative group work (Feedback Control). The results of practical examination have shown that students' performances and their attendance have become significantly better than previous year. We have also observed that students have been becoming greater autonomy and positive attitude in practical class. From those results, we can say that this support system might work effectively.
