亚里士多德哲学对实践活动(praxis)和技术活动(techne)作出明确的区分,但是,如何处理两者之间的关系,是一件有关反思的事情。哈贝马斯规范语用学思想涉及的有效性条件对这个问题具有一定的积极意义。据此,"理解"、"课堂对话"、"教师的角色"都得以重建。课堂对话分化出交往行动式、潜在的策略行动、策略行动、纯粹的权力运用等四大谱系。  相似文献

Professor Gordon argues for a significant reorientation in the focus and impact of assessment in education. For the types of assessment activities that he advocates to prosper and positively impact education, serious attention must be paid to two important topics: (1) the conceptual underpinnings of the assessment practices we develop and use to support learning and instruction, and (2) the arguments and evidence we establish for their validity given the intended interpretive use. Such a focus highlights fundamental concepts that have long existed in the broader assessment literature – carefully defining and operationalizing our constructs and then validating the assessments of those constructs. What differs now are the conceptual frameworks, briefly outlined here, that can and must be used to guide both aspects of such work.  相似文献

Abstract

This study assessed the reliability and validity of segment measured accelerations in comparison to front foot contact (FFC) ground reaction force (GRF) during the delivery stride for cricket pace bowlers. Eleven recreational bowlers completed a 30-delivery bowling spell. Trunk- and tibia-mounted inertial measurement units (IMUs) were used to measure accelerations, converted to force, for comparisons to force plate GRF discrete measures. These measures included peak force, impulse and the continuous force–time curve in the vertical and braking (horizontal) planes. Reliability and validity was determined by intra-class correlation coefficients (ICC), coefficient of variation (CV), Bland–Altman plots, paired sample t-tests, Pearson’s correlation and one-dimensional (1D) statistical parametrical mapping (SPM). All ICC (0.90–0.98) and CV (4.23–7.41%) were acceptable, except for tibia-mounted IMU braking peak force (CV = 12.44%) and impulse (CV = 18.17%) and trunk vertical impulse (CV = 17.93%). Bland–Altman plots revealed wide limits of agreement between discrete IMU force signatures and force plate GRF. The 1D SPM outlined numerous significant (p < 0.01) differences between trunk- and tibia-located IMU-derived measures and force plate GRF traces in vertical and braking (horizontal) planes. The trunk- and tibia-mounted IMUs appeared to not represent the GRF experienced during pace bowling FFC when compared to a gold-standard force plate.  相似文献

网络舆情衍进指数构建与实证分析   总被引:1,自引:0,他引:1  
[目的/意义]提出和构建网络舆情衍进指数,以描述网络舆情演化过程中常衍生出新的子话题的现象,对于舆情预警、预测具有重要的理论及实践意义。[方法/过程]以文本聚类结果和文本聚类有效性为依据,提出网络舆情衍进的判别标准和舆情衍进指数的构建过程,并以"教科书老赖"这一事件作为样本数据进行实证分析。[结果/结论]所构建的舆情衍进速率指数可以用于描述舆情衍进。在突发期阶段话题舆情衍进指数最高,此后逐渐下降,这一阶段的舆情衍进最为剧烈,子话题的出现呈现爆发性增长;舆情衍进指数在舆情蔓延期内出现阶梯式下降,此后保持为负值,舆情的子话题开始逐渐减少,舆情内容本身由发散转为收敛;进入消散期后,子话题数量趋于稳定。作为舆情衍进速率的测度和舆情衍进的判别方式,舆情衍进指数为舆情监管和舆情预警提供了全新的角度。  相似文献

One of the productive lines of research on self-assessment (SA) and peer assessment (PA) concerns their concurrent validity with respect to a criterion measure. However, similar research has rarely been conducted for spoken-language interpreting. This article therefore reports on a longitudinal study that investigated the validity of self and peer ratings on three performance dimensions of English-Chinese consecutive interpretation (i.e., information completeness, fluency of delivery, and target language quality), taking teachers’ ratings as a yardstick. Major findings include: although the students as a group were unable to replicate teachers’ ratings, they were able to rank-order their performances in a fairly accurate manner and improved their SA and PA accuracy over time. Interpreting directionality seems to moderate the correlational strength of self/teacher ratings and peer/teacher ratings. These results are discussed in relation to previous literature, and pedagogical suggestions are provided to improve SA and PA for bi-directional interpretation.  相似文献

Self‐report inventories are commonly administered to measure social‐emotional learning competencies related to college and career readiness. Inattentive responding can negatively impact the validity of interpreting individual results and the accuracy of construct validity evidence. This study applied nine methods of detecting insufficient effort responding (IER) to a social‐emotional learning assessment. Individual methods identified between 0.9% and 20.3% of respondents as potentially exhibiting IER. Removing flagged respondents from the data resulted in negligible or small improvements in criterion‐related validity, coefficient alpha, concurrent validity, and confirmatory factor analysis model‐data fit. Implications for future validity studies and the operational use of IER detection for social–emotional learning assessments are discussed.  相似文献

ABSTRACT

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ’s concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ’s test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ’s inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ’s ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children’s swimming competence, in terms of swimming distance and basic water survival skills.  相似文献

对以体育竞赛为核心内容的体育赛事立法是国际通行做法,目的就是要在有关体育赛事法律的保障下使得体育竞赛的各事项正常有序进行。体育赛事立法效力就是指拥有立法权的部门或依法受权立法部门针对体育赛事运行阶段所制定、修改、补充和废止一些规范性文件,在具体实施过程中所产生的效果和作用力。体育赛事运行涉及的人多、事杂、域广,其聚集性、综合性和体验性等特点决定了体育赛事立法效力具有时空相对聚集、立法层级较低、对象范围有限、公共权利保障性与包容性兼备等特殊性;影响其立法效力的因素主要有从体育赛事运行的秩序化客观需求出发的现实性、立法活动的合法性、立法程序的有效性、法律位阶的层级性及立法内容的专业性。  相似文献
