Effects of type of multimedia strategy on learning of Chinese characters for non-native novices

The purpose of this study was to examine the effects of multimedia strategies for instructional techniques and practice on non-native novices' Chinese character learning performance and cognitive load. Two types of multimedia instructional presentations – radical-highlighted and stroke-pronunciation – and two types of practice – visual cue and voice cue – were implemented. Participants were 81 non-native novices randomly assigned to one of the four experimental groups, namely radical-highlighted visual-cue, radical-highlighted voice-cue, stroke-pronunciation visual-cue and stroke-pronunciation voice-cue. An Internet-based e-learning course on the basis of Chinese characters was implemented and delivered as experimental instruction using a Moodle platform. The results show that, for non-native novices, the stroke-pronunciation (SP) strategy of showing strokes with pronunciations is better than the radical-highlighted (RH) strategy, enabling the novices to achieve better performance in identifying Chinese radicals. The significant two-way interactions suggest that (1) the SP presentation should be delivered with the voice-cue (VoC) practice to elicit better performance in writing and in identifying characters and strokes, and (2) the RH presentation should be delivered with visual-cue (ViC) practice to elicit better performance in character writing. Furthermore, participants showed similar levels of perceived cognitive load toward the stroke-based task and the radical-based task. However, when the SP presentation was delivered with the VoC practice, participants revealed lower perceived cognitive load toward the writing task.     

A cognitive component analysis approach for developing game-based spatial learning tools

Spatial ability has been recognized as one of the most important factors affecting the mathematical performance of students. Previous studies on spatial learning have mainly focused on developing strategies to shorten the problem-solving time of learners for very specific learning tasks. Such an approach usually has limited effects on improving the mathematical performance of students. In this study, a cognitive analysis approach is proposed for developing spatial learning tools by taking game characteristics into consideration. Moreover, the validation of the cognitive components of the spatial sense test for constructing two different kinds of intervention is verified, and the effects of the interventions are compared. To evaluate the performance of the proposed approach, an experiment was conducted on the mathematics course of an elementary school. The experimental results show that the spatial learning tool promotes not only the learning achievement, but also the spatial sense of the students.

基于多分支认证树的多用户多副本数据持有性证明方案

在云存储环境下,如何高效、动态地完成对多用户多副本数据的完整性验证是一个挑战性问题。基于双线性代数映射的签名机制和多分支认证树特性,提出了一种新的多用户多副本数据持有性证明方案。该方案通过使用随机掩码技术对密文进行处理确保数据隐私性,采用多分支认证树来提高数据分块的签名效率,能够支持数据动态更新操作。此外,引入第三方审计者对多用户多副本数据进行批量审计以减少计算开销。最后,分析表明本方案具有较高的安全性和效率。     

高职院校《电路分析》课程开放式考核方式的探索

传统的电路分析课程考核模式主要存在考核内容缺乏实践性、考核模式较为单一、成绩评价欠公平、缺少对考核结果的信息反馈等弊端。高职院校的学生普遍文化基础薄弱,学习动力不足,缺少有效的学习方法,自主学习意识和能力不强。针对高职学生的特点,建立“理论与技能相结合,过程与结果相结合”的多元化开放式考核评价体系,能更好地体现评价主体与评价内容、方式的“多元化”,突出考核内容与资源的“开放性”,以评促学,全面锻炼、提高和考察学生的综合素质。     

Payment and audit mechanisms for non private‐funded PPP‐based infrastructure maintenance projects

The introduction of a non private‐funded public–private partnerships (PPP) approach to the maintenance and operation of infrastructure facilities necessitates an equitable performance standard, a sensible penalty mechanism and a credible auditing system. Yet, with limited research on this type of scheme, it is not clear whether the payment and audit mechanisms can adequately gauge the performance of private partners and truly reflect the quality of service provided in their payment. The question is whether the reliability of the payment reduction and auditing mechanisms pertinent to the non‐private funded PPP infrastructure maintenance can be systematically verified. With reference to a case study in Hong Kong, field data have been collected and tested according to the sensitivity analysis and level of confidence. The results indicate that the level of payment reduction due to poor performance is fair and the audit frequency is adequate to reflect the overall performance of the service provider. The approaches adopted in this research should provide an objective basis for public and private partners to formulate a mutually acceptable and effective mechanism for non private‐funded PPP infrastructure maintenance contracts.
