The Relationship Between Tutoring Mode and Learners’ use of Help Tools in Distance Education

This article presents an experimental study demonstrating how 120 learners use help tools in a virtual learning set-up. More specifically, several types of tutoring are investigated to find out the extent of the use of help tools in each. The effects of two independent variables which may have an impact on the behaviour of learners are studied: (1) whether or not they have access to a human tutor (HT) and (2) the tutor’s means of intervention (reactive or proactive). One of the goals of the study is to determine whether these modes of tutoring can influence positively or negatively distance learners’ use of lexical, conceptual, metacognitive and navigational help tools. The results of analysis of variance show that it is useless to prompt (effect of proactivity) learners to use the help that is available to them but that prompting is sometimes more subtle than initially foreseen. It appears that the presence of an HT pushes learners to use help tools, but this effect (of the presence of the HT) is still relatively weak and therefore may not justify the cost of employing a human tutor. It is also important to show the necessary intrinsic quality of the tools made available in order for a given mode of tutoring to have an effect on their use.     

Investigating the role of Minecraft in educational learning environments

This research paper identifies the way in which Minecraft Edu can be used to contribute to the teaching and learning of secondary students via a multiple case research study. Minecraft Edu is recognised as a gamification tool that enables its users to create and evaluate project-based learning activities within a classroom context. Learning through edugames was found to enhance learning as well as allow students to attain overall learning outcomes. This permitted an enhancement of engagement, collaboration, the creation of authentic learning activities as well as the attainment of learning outcomes. The role of the teacher was also found to play a considerable role in students attaining these twenty-first-century teaching and learning capabilities.

介绍了机械优化设计理论的基本思想及其求解方法，将其应用于机床主轴的结构设计，建立了机床主轴结构优化设计的数学模型，并用内点惩罚函数法求解模型，得到了整体最优的结构设计方案，使机床主轴在满足各种约束要求条件下，刚度最好，材料最省。文中结合一实例分析其优化设计全过程。实例证明优化理论在机械设计中具有实用价值。     

改革开放以来我国研究生教育改革政策的变迁——基于词频统计方法和政策工具的视角

改革开放以来,随着我国研究生教育改革政策的陆续出台,研究生教育政策体系初步形成。借助词频统计方法,发现改革开放以来我国研究生教育改革政策的变迁历经了四个阶段,即:1978—1985年的恢复重建阶段,1986—1998年的调整发展阶段,1999—2012年的深化改革阶段,2013年至今的内涵发展阶段。各个阶段具有较好的连贯性和一致性,同时呈现出独特的阶段性特征。在政策变迁的过程中,政策体系趋于完备,政策主体日渐多元。从政策工具理论的视角来看,供给型、环境型、需求型政策工具均有涉及,但不同阶段发挥的作用不均衡,供给型政策工具比例明显高于其他两类政策工具比例。建议深化教育体制改革,强化教育政策制定与施行办法,优化并综合运用政策工具。
