现代医学模式要求口腔修复在恢复患者口腔正常生理功能的基础上 ,还要满足患者心理的需要。口腔修复设计在口腔修复过程中起着至关重要的作用。口腔修复医生必须综合考虑口腔修复设计的各个要素 ,包括患者因素、医疗机构因素、医务人员因素 ,并正确处理这些要素之间的关系 ,才能为患者做出修复体的最佳设计 相似文献

Over 10 years have passed since the publication of Carr and Burkholder's (1998) technical article on how to construct single‐subject graphs using Microsoft Excel. Over the course of the past decade, the Excel program has undergone a series of revisions that make the Carr and Burkholder paper somewhat difficult to follow with newer versions. The present article provides task analyses for constructing various types of commonly used single‐subject design graphs in Microsoft Excel 2007. The task analyses were evaluated using a between‐subjects design that compared the graphing skills of 22 behavior‐analytic graduate students using Excel 2007 and either the Carr and Burkholder or newly developed task analyses. Results indicate that the new task analyses yielded more accurate and faster graph construction than the Carr and Burkholder instructions. 相似文献

This study proposes a new item parameter linking method for the common-item nonequivalent groups design in item response theory
(IRT). Previous studies assumed that examinees are randomly assigned to either test form. However, examinees can frequently
select their own test forms and tests often differ according to examinees’ abilities. In such cases, concurrent calibration
or multiple group IRT modeling without modeling test form selection behavior can yield severely biased results. We proposed
a model wherein test form selection behavior depends on test scores and used a Monte Carlo expectation maximization (MCEM)
algorithm. This method provided adequate estimates of testing parameters. 相似文献

Several criteria from the optimal design literature are examined for use with item selection in multidimensional adaptive
testing. In particular, it is examined what criteria are appropriate for adaptive testing in which all abilities are intentional,
some should be considered as a nuisance, or the interest is in the testing of a composite of the abilities. Both the theoretical
analyses and the studies of simulated data in this paper suggest that the criteria of A-optimality and D-optimality lead to
the most accurate estimates when all abilities are intentional, with the former slightly outperforming the latter. The criterion
of E-optimality showed occasional erratic behavior for this case of adaptive testing, and its use is not recommended. If some
of the abilities are nuisances, application of the criterion of A
s
-optimality (or D
s
-optimality), which focuses on the subset of intentional abilities is recommended. For the measurement of a linear combination
of abilities, the criterion of c-optimality yielded the best results. The preferences of each of these criteria for items with specific patterns of parameter
values was also assessed. It was found that the criteria differed mainly in their preferences of items with different patterns
of values for their discrimination parameters.

前景理论回答了类似应聘者在结构化面试中所面临的不确定场景下,人们是如何决策并行动的问题。论文采用思辨方法就结构化面试问题设计中如何恰当应用前景理论的基本要.董,有效提高结构化面试效度进行了探讨,结论如下:1)问题句子越短、问题越具体,效度有望越高;2)问题导向性要与岗位胜任特征充分契合;3)回溯性行为面试问题效度要高于虚拟情景面试问题;4)由于年龄、性别及个体认知能力等方面的差异,问题设计不仅要因需而变,也要因人而异。 相似文献

In this 2-experiment study, experimental analyses of phoneme blending and segmenting skills were conducted with four-first
grade students. Intraindividual analyses were conducted to identify the effects of classroom-based instruction on blending
phonemes in Experiment 1. In Experiment 2, the effects of an individualized intervention for the student who failed to improve
in the first experiment were examined. Stimulus materials were drawn directly from the classroom curriculum, making it possible
to monitor students’ response to classroom instruction and intervention over time. Generalization of responding to unique
letter combinations was measured. A multiple-probe across tasks designs was used in both studies. Results indicated that all
students improved their phoneme blending skills and are discussed in terms of the need for evaluation methods that are sensitive
enough to identify individual differences in responding between students and to detect within-student performance increases
in critical early literacy skills. 相似文献

为了探讨英语多媒体学习中言语关联手势对认知负荷及学习成绩的影响,采用2×2被试间实验设计。结果发现:该手势对认知负荷影响的主效应不显著,但与英语语言技能水平之间存在交互作用,当学生语言技能水平低时,手势增加了认知负荷,反之,则降低认知负荷;该手势对句子转换的成绩没有明显影响,但在学生语言技能高时能提升理解能力的成绩。本研究结果提示,言语关联手势的运用有明显作用,它能提高或降低认知负荷,并对理解能力的成绩产生影响,但其大小和方向依赖于学生英语语言技能水平。 相似文献

通过两个实验探讨多媒体学习中情绪设计对学习者情绪、认知过程和学习结果的影响。实验1将内部情绪设计与外部情绪诱发两种方式结合起来,探讨多媒体学习环境中不同方式诱发的积极情绪对学习的影响。实验2进一步聚焦于内部情绪设计,考察颜色和拟人化这两个特定的情绪设计元素对学习者情绪和学习的影响。结果发现:(1)积极的外部情绪诱发和内部情绪设计可以诱发积极情绪,并促进学习迁移。(2)对学习材料进行内部积极情绪设计可以诱发学习者积极情绪,增强学习者的学习动机,降低学习者感知到的学习材料的难度,并促进学习迁移。其中,彩色设计可以诱发学习者积极情绪,但拟人化只有与彩色结合才能诱发学习者积极情绪;在拟人化条件下,彩色设计可以增强学习者学习动机;彩色设计可降低学习者对学习材料感知到的难度;彩色和拟人化都可以促进学习迁移。 相似文献
