排球运动中内隐学习效果的探讨

外显学习和内隐学习是学生在技能获得中的两种学习方法,他们相互协同,在一定条件下相互转化.本研究采用内隐学习和外显学习相结合的教学方法,探讨了排球扣球技术教学中利用内隐学习的教学效果.结果表明:在排球扣球技术中采用内隐学习和外显学习相结合的方法能够提高学生对技术要领掌握的清晰性;能够提高学生在应激条件下技术发挥的稳定性,提高扣球的成绩;能够提高学生对课堂的积极情绪,提高学生的主观幸福感.     

《神雕侠侣》疏漏指证

《神雕侠侣》是金庸最重视的一部武侠小说。由于小说时间跨度长，人物众多且经历曲折，多条情节线索交叉发展极其复杂，尽管作家尽了最大努力，但疏漏仍难完全避免。本对小说人物、环境描写、情节发展等方面的矛盾抵牾之处作了指证。     

Are they paying attention? Students’ lack of motivation and attention potentially threaten the utility of course evaluations

Student evaluations are a common source of information used by instructors and administrators, but their utility depends on students’ motivation and attention. This paper presents evidence from two studies indicating that insufficient effort responding and lack of motivation may be problems in course evaluations. In the first study, approximately one in four students responded in an improbable way to ‘catch items’ embedded in actual course evaluation instruments, suggesting a lack of attention. In the second study, students’ responses to an online survey indicated that they doubted that their responses to course evaluations would be used by instructors or administrators. The majority of students admitted to only occasionally putting sufficient effort into their responses. Potential means for identifying insufficient effort responding and mechanisms for increasing student attention and motivation during the course evaluation process are discussed.

A framework for Internet of Things-enabled smart government: A case of IoT cybersecurity policies and use cases in U.S. federal government

Internet of Things (IoT) is ubiquitous in society. IoT-enabled dynamic capabilities in real-time sensing and responding can spur digital transformation in unlocking the potential of digital government into data-driven smart government capable of delivering policies and services of public interest and public value. However, the literature indicates challenges in IoT cybersecurity and systemic use across the government. There is the urgent need for IoT research on policy and use. This paper developed a framework for IoT-enabled smart government performance. We applied this framework to conduct case study analyses of digital technology policy, IoT cybersecurity policy, and IoT use in major application domains at the U.S. federal government level. The results show that some agencies were strategic and forward-thinking in funding and partnering with sub-national governments in promoting the IoT use. However, there remains a critical need for national IoT policies to promote systemic IoT use across the application domains.     

构建行政首长出庭应诉制度管见

《中华人民共和国行政诉讼法》颁布17年来,行政审判的司法环境大为改善,“民告官”的积极性不断提高,官应诉的自觉性不断增强。2004年3月,国务院《全面推进依法行政实施纲要》出台后,全国各地相继推行行政首长出庭应诉制度。然而,在司法实践中,由于认识上的不一,制度上的欠缺,各地行政首长出庭应诉工作开展得还很不平衡．亟需进一步构建完善。     

资产证券化是解决不良贷款之有效方式

我国银行体系中不良贷款问题日益严峻,深入剖析不良贷款问题的现状、分析其理论和现实根源、探索解决银行不良贷款问题的思路已成当务之急．通过证券化,银行可以提前收回现金,提升不良资产的潜在价值．在美国、意大利、日本和韩国等经济发达国家,已有大量成功先例．由于中国的不良资产证券化缺乏稳定的现金流,体现出了独特的中国特色,加上法律、会计、税收、监管等方面都缺乏配套的规定,所以,必须加强不良资产证券化的基础条件建设．     

A Polytomous Scoring Approach to Handle Not-Reached Items in Low-Stakes Assessments

In low-stakes assessments, some students may not reach the end of the test and leave some items unanswered due to various reasons (e.g., lack of test-taking motivation, poor time management, and test speededness). Not-reached items are often treated as incorrect or not-administered in the scoring process. However, when the proportion of not-reached items is high, these traditional approaches may yield biased scores and thereby threatening the validity of test results. In this study, we propose a polytomous scoring approach for handling not-reached items and compare its performance with those of the traditional scoring approaches. Real data from a low-stakes math assessment administered to second and third graders were used. The assessment consisted of 40 short-answer items focusing on addition and subtraction. The students were instructed to answer as many items as possible within 5 minutes. Using the traditional scoring approaches, students’ responses for not-reached items were treated as either not-administered or incorrect in the scoring process. With the proposed scoring approach, students’ nonmissing responses were scored polytomously based on how accurately and rapidly they responded to the items to reduce the impact of not-reached items on ability estimation. The traditional and polytomous scoring approaches were compared based on several evaluation criteria, such as model fit indices, test information function, and bias. The results indicated that the polytomous scoring approaches outperformed the traditional approaches. The complete case simulation corroborated our empirical findings that the scoring approach in which nonmissing items were scored polytomously and not-reached items were considered not-administered performed the best. Implications of the polytomous scoring approach for low-stakes assessments were discussed.
