The aim of this study was to develop and validate an instrument of inclusive teachers’ competencies for teaching students with special educational needs in China. Data were obtained from a preliminary and large-scale investigation in Beijing. The primary analyses included exploratory factor analysis and confirmatory factor analysis. The findings indicated that Chinese inclusive teachers’ competency is underpinned by four factors: teaching and instruction; communication and cooperation; attitudes and beliefs; and reflection and development. The four-factor model was obtained with satisfactory reliability and validity. The validated questionnaire generated a theoretical understanding of inclusive education teachers’ competency in China. In addition, the findings of the study provided knowledge that will allow for the development of professional standards and teacher education programmes for inclusive education. 相似文献

The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students’ inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA. 相似文献

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease. 相似文献

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9. 相似文献

借鉴社会认知框架中的“认知效度”和“语境效度”框架,对《全新版大学英语听说教程》(第二版)全6册教材中听力测试任务的效度进行评价。研究发现,教材中的听力习题对不同层次的听力认知能力考查不够全面,对听力元认知策略的培养体现不够突出,对作答过程中的书写负担控制不够。此外,建构性作答方式听力任务的设计有待系统性改进,听力语篇真实性有待提升,听力和口语任务的衔接不够紧密。针对这些问题,建议听力任务设计遵从科学严谨的测试编写方法和原则,以提升听力习题的认知效度和语境效度,并在此基础上进一步考察其在实际教学中的使用效果及师生反馈。 相似文献

In all sectors of the economy, the importance of innovation is underlined. Although education plays a central role in the development of human innovation skills, several studies suggest that higher education institutions cannot fulfill these demands. In such, there is a need to update pedagogical practices and develop assessment tools to measure and develop a person’s innovation capacity. The aim of this study is to test and evaluate the functioning of the earlier developed assessment tool to measure students’ innovation competences in the authentic learning environments of Finnish higher education institutions. The electronic self-assessment questionnaire was distributed to students (n = 495) from four Finnish universities of applied sciences. The results showed that the questionnaire statements formed a functional innovation competence barometer for self-assessment, including creative problem-solving, systems thinking, goal orientation, teamwork, and networking competences. The assessment tool facilitates the development of teaching, assessing, and curriculum design in higher education. 相似文献

The argument-based approach to validation has been widely adopted in validation theory. However, this approach aims to validate the intended interpretation and use of a single test or assessment. This article proposes an extension of the argument-based approach for validation of multiple tests. This extension is illustrated with the validation of a competency assessment program (CAP). This CAP was validated in collaboration with a quality manager of an educational program. In this case study, it became apparent that this approach fosters an in-depth evaluation of the assessment program and that the approach appears suitable for validation efforts of competency assessment programs. The approach guides validation research from a more general perspective, but also guides more detailed validation efforts. 相似文献

Simulation models of heat and water transport have not been rigorously tested for the red soils of southern China.Based on the theory of nonisothermal water-heat coupled transfer, a simulation model, programmed in Visual Basic 6.0, was developed to predict the coupled transfer of water and heat in hilly red soil. A series of soil column experiments for soil water and heat transfer, including soil columns with closed and evaporating top ends, were used to test the simulation model. Results showed that in the closed columns, the temporal and spatial distribution of moisture and heat could be very well predicted by the model,while in the evaporating columns, the simulated soil water contents were somewhat different from the observed ones. In the heat flow equation by Taylor and Lary (1964), the effect of soil water evaporation on the heat flow is not involved, which may be the main reason for the differences between simulated and observed results. The predicted temperatures were not in agreement with the observed one with thermal conductivities calculated by de Vries and Wierenga equations, so that it is suggested that Kh, soil heat conductivity, be multiplied by 8.0 for the first 6.5 h and by 1.2 later on. Sensitivity analysis of soil water and heat coefficients showed that the saturated hydraulic conductivity, Ks, and the water diffusivity, D(θ), had great effects on soil water transport; the variation of soil porosity led to the difference of soil thermal properties, and accordingly changed temperature redistribution,which would affect water redistribution. 相似文献

完善高校教师质量评价方法对提高教师的教学水平和教学积极性具有重要意义。传统的评价方法以定性和简单算术运算分析为主,带有较强的主观片面性。可拓学是用形式化模型研究事物拓展的可能性和开拓创新的规律与方法,并用于解决矛盾问题的科学。教学质量评价指标的多样性和由单指标给出的评价结果的不相容性,符合可拓学解决矛盾问题的基本原则。利用可拓学理论和方法建立的高校教师教学质量评价物元模型,能在事先没有人为设计指标权重的基础上,通过关联函数和关联度,反应评价单元的归属程度以及评价等级值,较好地解决指标权重与主观片面性问题,为高校教师教学质量评价提供一种新的思路。 相似文献

信息意识是信息素养的重要组成部分,影响着信息主体的信息需求表达和信息行为,决定了信息的利用效果。当前关于信息意识的概念模糊,未能体现意识的流动性,使得该领域的研究和实践表层化、单一化,难以有效指导教学实施过程。明确信息意识概念有助于为相关研究提供一种可操作性的定义和交流理解的框架,为信息技术教学实践提供切实可行的指导思想。在心理学意识概念的基础上,结合信息素养的过程结构和目标结构思想,将信息意识界定为信息主体在信息认知活动中产生的感受及感受积累后形成的对信息活动的觉知能力,由信息行为觉知、信息情感、信息观点三要素和信息需求、信息应用、信息交流三阶段组成。探索性因素分析和验证性因素分析验证了该概念模型的合理性。 相似文献
