在梳理已有文献的基础上,将知识距离与学习能力这二方面引入到知识存量与科技成果转化关系中,构建知识距离、学习能力与知识存量、科技成果转化的概念模型,并运用结构方程模型进行实证检验。研究发现,知识存量对科技成果转化具有显著正向影响,其中知识距离发挥部分中介作用;学习能力对知识距离具有直接的正向影响,并且在知识存量与知识距离、知识存量与科技成果转化关系中发挥调节作用。     

Multimedia augmented m-learning: Issues,trends and open challenges

The advancement in mobile technology and the introduction of cloud computing systems enable the use of educational materials on mobile devices for a location- and time-agnostic learning process. These educational materials are delivered in the form of data and compute-intensive multimedia-enabled learning objects. Given these constraints, the desired objective of mobile learning (m-learning) may not be achieved. Accordingly, a number of m-learning systems are being developed by the industry and academia to transform society into a pervasive educational institute. However, no guideline on the technical issues concerning the m-learning environment is available. In this study, we present a taxonomy of such technical issues that can impede the life cycle of multimedia-enabled m-learning applications. The taxonomy is devised based on the issues related to mobile device heterogeneity, network performance, content heterogeneity, content delivery, and user expectation. These issues are discussed, along with their causes and measures, to achieve solutions. Furthermore, we identify several trending areas through which the adaptability and acceptability of multimedia-enabled m-learning platforms can be increased. Finally, we discuss open challenges, such as low complexity encoding, data dependency, measurement and modeling, interoperability, and security as future research directions.     

谈俄语学习兴趣的培养

近年来,随着英语的普及,非俄语专业学生对大学俄语课的学习兴趣逐渐减弱。只有通过有效地组织课堂教学及开展丰富多彩的课外活动,才能促进学生学习兴趣的提高。     

历史学术地理刍议——以20世纪80年代以来的历史学术地理研究为例

20多年来,在中国历史地理的研究中,关于学术相关问题的地理学研究取得了很多成果。在总结这些研究成果的基础上,对历史学术地理的内涵、研究对象及研究内容诸项进行分析、厘定及理论性的阐释,并因此建立完整的历史学术地理学术分支,已经成为可能。惟有如此,才能推动历史学术地理研究的进一步深入。     

数字化学习社区创建标准的研究

数字化学习社区的创建已经陆续在一些省市进行,但到目前为止,还没有统一的创建评估标准。建立科学、切实可行的创建评估标准,是大力推动和正确评估数字化学习社区建设的有效途径,也是亟待解决的问题。本文从数字化学习要素和特点出发,通过数字化学习社区的创建实践,对数字化学习社区的创建评估标准进行了深入的研究和探讨,提出了创建数字化学习社区的基本标准。     

Using log variables in a learning management system to evaluate learning activity using the lens of activity theory

As the advance of learning technologies and analytics tools continues, learning management systems (LMSs) have been required to fulfil the growing expectations for smart learning. However, the reality regarding the level of technology integration in higher education differs considerably from such expectations or the speed of advances in educational technologies. This research aimed to evaluate the current activation levels and usage patterns of a LMS. A large data-set was analysed, which included the online activity information from 7940 courses. Through data pre-processing, general indicators reflecting login frequencies of the virtual campus and activity-based indicators presenting the activation patterns of diverse functions provided by Moodle were derived. Activity theory was applied to interpret the results of analysis, since it has been recognised as a powerful framework to understand phenomena encompassing interactive systems. Further, time-series investigation over three consecutive semesters allowed observation of historical changes. The results revealed considerably low use of the virtual campus with only slight changes, as well as significantly different activity patterns across course attributes and colleges. Contradictions among components in the activity system are discussed, along with the implications for improving teaching and learning with LMS in higher education.     

The Role of Anatomy Computer-Assisted Learning on Spatial Abilities of Medical Students

Currently, medical education context poses different challenges to anatomy, contributing to the introduction of new pedagogical approaches, such as computer-assisted learning (CAL). This approach provides insight into students' learning profiles and skills that enhance anatomy knowledge acquisition. To understand the influence of anatomy CAL on spatial abilities, a study was conducted. A total of 671 medical students attending Musculoskeletal (MA) and Cardiovascular Anatomy (CA) courses, were allocated to one of three groups (MA Group, CA Group, MA + CA Group). Students' pre-training and post-training spatial abilities were assessed through Mental Rotations Test (MRT), with scores ranging between 0-24. After CAL training sessions, students' spatial abilities performance improved (9.72 ± 4.79 vs. 17.05 ± 4.57, P < 0.001). Although male students in both MA Group and CA Group show better baseline spatial abilities, no sex differences were found after CAL training. The improvement in spatial abilities score between sessions (Delta MRT) was correlated with Musculoskeletal Anatomy training sessions in MA Group (r = 0.333, P < 0.001) and MA + CA Group (r = 0.342, P < 0.001), and with Cardiovascular Anatomy training sessions in CA Group (r = 0.461, P = 0.001) and MA + CA Group (r = 0.324, P = 0.001). Multiple linear regression models were used, considering the Delta MRT as dependent variable. An association of Delta MRT to the amount of CAL training and the baseline spatial abilities was observed. The results suggest that CAL training in anatomy has positive dose-dependent effect on spatial abilities.     

The articulation of the development of teacher knowledge during the implementation of new teaching procedures to enhance student understanding of molecular biological concepts

This paper is based on the first author’s extensive examination of her teaching and her students’ learning in a senior high school Biology classroom at a coeducational K-12 independent college in Victoria, Australia, over a five-year period. Research was guided by the following questions: (1) How can students become more aware of the specific biological terminology that they will need to use to communicate their understanding of biological concepts? (2) How can student familiarity with new biological terminology be enhanced? (3) Which teaching strategies might be most effective across the diverse range of abilities and learning styles within a senior Biology classroom? Three key data-sets ([1] Development of specific teaching procedures; [2] Student responses to using the teaching procedures; [3] Teacher journal entries and reflections) were analysed supported by Korthagen’s ALACT model. Findings support the notion that genuine educational change is linked to teacher change, driven by teachers themselves, drawing new insights into students’ learning.
