摘要：
In an effort to address student engagement challenges, much research has explored student-to-student connected classroom climate (CCC). Research positively associates CCC to the benefits of student integration, learning, and retention in face-to-face environments. However, few studies have examined CCC in computer-mediated environments. This study provides empirical evidence of the relationships between key technological factors and CCC in cloud classrooms. A survey was administered to 641 college students, and the results indicate that four of the five technological factors examined were positively associated with CCC: advanced computer self-efficacy, program/software computer experience, Internet/entertainment computer experience, and computer importance. Basic computer self-efficacy was not related to CCC. These findings identify mechanisms that can improve CCC in cloud classrooms. Researchers and practitioners should use this knowledge to develop, implement, and assess the cloud classroom. In addition, this study contributes knowledge that can direct student training of digital literacies for improving the learning processes of cloud classrooms in higher education.

摘要：
This paper addresses a coordination problem of production and green transportation and the effects of production and transportation coordination on supply chain sustainability in a global supply chain environment with the consideration of important realistic characteristics, including parallel machines, different order processing complexities, fixed delivery departure times, green transportation and multiple transportation modes. We formulate the measurements for carbon emissions of different transportation modes, including air, sea and land transportation. A hybrid genetic algorithm-based optimization approach is developed to handle this problem, in which a hybrid genetic algorithm and heuristic procedures are combined. The effectiveness of the proposed approach is validated by means of various problem instances. We observe that the coordination of production and green transportation has a large effect on the overall supply chain sustainability, which can reduce the total supply chain cost by 9.60% to 21.90%.
摘要：
Research indicates that learning from erroneous examples (EE) is superior to correct examples because errors may provide students with a stimulus to spontaneously produce more self-explanations, leading to better learning outcomes. However, because most studies were conducted in individual settings, it remains an open question whether the advantage of EE could be reproduced in collaborative settings. Therefore, this study used a 2 × 2 factorial design varying in example types (correct vs. erroneous examples) and learning settings (individuals vs. collaboration). An experimental study of a 2-week course on subtraction for third grade students was conducted (N = 109). Results indicated that collaborative learning may enhance the transfer knowledge of subtraction. The improvements were still maintained over 2 weeks. In addition, collaboration also facilitated students’ confidence in handling errors. However, there was no significant difference in promoting isomorphic and transfer knowledge between learning from correct and erroneous examples. Additionally, this study also explored the absence of the intended benefit of erroneous examples from a cognitive load perspective.

摘要：
This study examined how to foster pupils' mathematical communication abilities by using tablet PCs. Students were encouraged to generate math creations (including mathematical representation, solution, and solution explanation of word problems) as their teaching materials and reciprocally tutor classmates to increase opportunities for mathematical communication during a semester. A reciprocal peer-tutoring-enhanced mathematical communication system was designed for supporting students' math creations and reciprocal peer-tutoring activities. An experiment involving 51 second-graders was conducted to evaluate their improvement in mathematical communication abilities. While the control group received one-to-one self-learning mathematical materials and teacher-led instruction, the experimental group was engaged in computer-supported reciprocal peer tutoring in the same environment with the same materials. Both groups were evaluated by using a mathematical communication ability assessment. The result indicated that the experimental group outperformed the control group in the assessment. Additionally, math creations were analyzed for assessing students' formative development. The results showed that students' math creations became clearer and more efficient. In other words, their mathematical representations and solution explanations became more accurate after the learning activity.

摘要：
With the ever-deepening economic reform and international trend of ICT application in education, the Chinese government is strengthening its basic education curriculum reform and actively facilitating the application of ICT in education. Given the achievement gap of ICT infrastructure and its application in middle and primary schools between urban and rural areas, a divide exists between the needs of constructing ICT infrastructure and the patterns of promoting ICT application in education. This paper reports a survey conducted on the infrastructure and application of ICT in middle and primary schools in urban areas (city and county) and rural areas in China based on their demands for promoting ICT in education. The survey focused on 2,168 middle and primary schools, including 717 schools in cities (33.1%), 487 schools in counties (22.5%) and 964 schools located in rural areas (44.5%). Based on stepwise regression analysis, it was revealed that ICT infrastructure had different influences on its application for schools in urban and rural areas. Schools' proportion of ICT aided courses in counties, and utilization of multi-media classrooms in rural areas may be more associated with the infrastructure. These conclusions would be particularly useful for policy-makers in Asia. Moreover, the analysis model could highlight some areas where improvement plans could be implemented to reduce the digital divide. However, ICT infrastructure was found to play an insignificant role in "utilization of multi-media classrooms" or "proportion of ICT aided courses" in city schools, and thus its role in city schools should be reinterpreted.
