5G and Smart Education: Educational Reform Based on Intelligent Technology

The 5G communication technology serving a wide range of vertical industries is maturing, which provides a possible boost for the development of smart education and lays a foundation for solving the principal contradiction in current education. With the characteristics of ultra-high speed, low latency, low energy consumption, massive network capacity, and high reliability, the 5G technology is applied with other technologies like artificial intelligence (AI), internet of things (IoT), big data, and blockchain to promote the application upgrading of intelligent education technology. This paper analyzes the intelligent education technology and its eight typical applications in the 5G era, which include smart safe campus, integrated learning spaces, synchronous cyber classrooms, teachers’ professional development, robot learning partners, mobile and ubiquitous learning, virtual simulation training, and smart e-textbooks. Then, it discusses how intelligent education technology promotes changes in the modes of learning and teaching in the 5G era from three dimensions: individual learning, collaborative group learning, and classroom-based collective teaching. At last, the framework of smart education in the 5G era is proposed from the perspectives of intelligent education technology and its typical applications, changes in learning and teaching, and the new ecosystem of smart education.

The Effect on Enhancing Students＇ Inquiry Abilities via Step-by-Step Open-ended Inquiry Teaching Design

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel＇s proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification （from levels of inquiry 0 to 2b） and to combine the experimental teaching method with the 5E （engage, explore, explain, elaborate, and evaluate） learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders＇ basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the ＂predicting＂ dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on ＂interpreting data＂ as well as ＂experiment designing＂ dimensions. Hence, the study indicated that it could enhance students＇ inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.
