为检验高中物理学业水平合格性考试试题与课程标准的一致性,采用SEC模型,从知识内容和认知水平两个方面分析试题与物理课程标准的一致性程度,从试题看核心素养测试的探索。研究结果表明,2022年三个省高中物理学业水平合格性考试试题与课程标准不具备统计学意义上的显著一致性。试题对物理学科核心素养测试进行了积极探索,但仍存在有待改进的方面。最后提出依据课程标准的内容要求落实素养全面考查,遵循学业质量要求合理设置试题难度和题型,基于物理学科的本质实现科学探究能力的有效测评等建议。 相似文献

预估难度的理论模型及应用探析 总被引：7，自引：1，他引：6
难度决定考试分数的分布,直接影响考试的评价与选拔功能,受到较高的关注。难度一般通过考后对考试数据的统计分析得到,这时合格分数线巴经确定,无法再进行调整。预估难度是在命题阶段由命题专家结合试题内容,通过构建标准常模,进行合理地评定而得到的试题难度。在当前应用愿始分报告考试成绩的情况下,预估难度对确保考试稳定与公平尤其重要。预估难度不同于实测难度,可以进行控制与调整。命题工作不仅是编制试题的过程,而且是预估难度的设计过程。 相似文献

ABSTRACTThe understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item characteristics that could influence the item’s proficiency level. It is based on an a-priori item analysis and a statistical analysis. Results show that only the cognitive complexity and the format out of the different characteristics of PISA science items determined in our a-priori analysis have an explanatory power on an item’s proficiency levels. The proficiency level cannot be explained by the dependence/independence of the information provided in the unit and/or item introduction and the competence. We conclude that in PISA, it appears possible to anticipate a high proficiency level, that is, students’ low scores for items displaying a high cognitive complexity. In the case of a middle or low cognitive complexity level item, the cognitive complexity level is not sufficient to predict item difficulty. Other characteristics play a crucial role in item difficulty. We discuss anticipating the difficulties in assessment in a broader perspective. 相似文献

高中学业水平考试:功能、命题与成绩使用 总被引：1，自引：0，他引：1
高中学业水平考试是新课程改革背景下出现的新型教育考试。它考查中学生的知识掌握水平、学科素养、学习能力,应该成为高校招生的重要评价指标之一,并能为社会用人单位提供有用的信息。高中学业水平考试的命题组卷,应关注的首要指标是试题有无较全面地覆盖课程标准要求的内容,以及试题的难度范围是否足够广泛。作为高考招生的指标之一,高中学业水平考试成绩合格或达到一定等级应该成为一个关键的录用前提条件。至于考生取得哪个等级的学业水平考试成绩可以被录用,则最终取决于招生院校和专业的要求。 相似文献

Using a New Statistical Model for Testlets to Score TOEFL 总被引：1，自引：0，他引：1
Standard item response theory (IRT) models fit to examination responses ignore the fact that sets of items (testlets) often are matched with a single common stimulus (e.g., a reading comprehension passage). In this setting, all items given to an examinee are unlikely to be conditionally independent (given examinee proficiency). Models that assume conditional independence will overestimate the precision with which examinee proficiency is measured. Overstatement of precision may lead to inaccurate inferences as well as prematurely ended examinations in which the stopping rule is based on the estimated standard error of examinee proficiency (e.g., an adaptive test). The standard three parameter IRT model was modified to include an additional random effect for items nested within the same testlet (Wainer, Bradlow, & Du, 2000). This parameter, γ characterizes the amount of local dependence in a testlet.
We fit 86 TOEFL testlets (50 reading comprehension and 36 listening comprehension) with the new model, and obtained a value for the variance of γ for each testlet. We compared the standard parameters (discrimination (a), difficulty (b) and guessing (c)) with what is obtained through traditional modeling. We found that difficulties were well estimated either way, but estimates of both a and c were biased if conditional independence is incorrectly assumed. Of greater import, we found that test information was substantially over-estimated when conditional independence was incorrectly assumed. 相似文献

依据SOLO分类理论对2020年实施新高考的北京、天津、山东、海南四省市普通高中学业水平等级考试化学试题的能力结构进行比较分析,探查试题的命制特点和规律。研究发现:2020年四省市化学试题在SOLO各结构水平层次上均有涉及,多元结构水平和关联结构水平试题占比较高,体现了试题的选拔性;试题中各知识模块的SOLO结构水平层次分布整体均衡,试题内容全面,注重对基础知识的考查,体现了试题的基础性。为了进一步优化化学课堂教学、促进学生全面发展,中学化学教师可以从以下几个方面着手:对标学业质量标准,统筹规划教学的深度与广度;重视实际问题解决,加强学科素养和关键能力的培养;加强教学情境创设,重视创新意识和迁移应用能力的培养;优化课堂教学设计,重视学生高阶思维能力的培养。 相似文献

Empirical studies demonstrated Type-I error (TIE) inflation (especially for highly discriminating easy items) of the Mantel-Haenszel chi-square test for differential item functioning (DIF), when data conformed to item response theory (IRT) models more complex than Rasch, and when IRT proficiency distributions differed only in means. However, no published study manipulated proficiency variance ratio (VR). Data were generated with the three-parameter logistic (3PL) IRT model. Proficiency VRs were 1, 2, 3, and 4. The present study suggests inflation may be greater, and may affect all highly discriminating items (low, moderate, and high difficulty), when IRT proficiency distributions of reference and focal groups differ also in variances. Inflation was greatest on the 21-item test (vs. 41) and 2,000 total sample size (vs. 1,000). Previous studies had not systematically examined sample size ratio. Sample size ratio of 1:1 produced greater TIE inflation than 3:1, but primarily for total sample size of 2,000. 相似文献

Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the evaluation of methodical‐didactic measures. Such a tool is theoretically anchored in an empirically validated geography‐didactic and cognition‐psychological competence model, providing a differentiated representation of both the internal structure of a competency and the proficiency levels. The starting point of this foundation was the development of a normative‐theoretically derived model of geographic system competence. Its empirical validation was performed in different phases aimed at operationalising the competence model by means of test problems. In order to analyse the factor structure of the theoretical model, various item response models were estimated. The item levels of difficulty expected in the competence model were related to the empirical levels of difficulty and predicted by means of ordinary least squares regression to verify the model for proficiency levels. The two‐dimensional competence model – with the two dimensions ‘system organisation and behaviour’ and ‘system‐adequate intention to act’ – exhibits a better fit in reference to the model fit criteria than the one‐dimensional and three‐dimensional models. The correlations between the expected and empirical item difficulties are positive. Items that should be more difficult according to the competence model are actually shown to be more difficult. These findings suggest the reliability and validity of this new measurement instrument for diagnosing and promoting geographical system competence. It has to be implemented in practice as the next step. 相似文献
