Standardization and UNDERSTANDardization in Educational Assessment     

Stephen G. Sireci 《Educational Measurement》2020,39(3):100-105

Educational tests are standardized so that all examinees are tested on the same material, under the same testing conditions, and with the same scoring protocols. This uniformity is designed to provide a level “playing field” for all examinees so that the test is “the same” for everyone. Thus, standardization is designed to promote fairness in testing. In practice, the material tested, the conditions under which a test is administered, and the scoring processes, are often too rigid to provide the intended level playing field. For example, standardized testing conditions may interact with personal characteristics of examinees that affect test performance, but are not construct-relevant. Thus, more flexibility in standardization is needed to account for the diversity of experiences, talents, and handicaps of the incredibly heterogeneous populations of examinees we currently assess. Traditional standardization procedures grew out of experimental psychology and psychophysics laboratories where keeping all conditions constant was crucial. Today, accounting for and measuring what is not constant across examinees is crucial to valid construct interpretations. To meet this need I introduce the concept of understandardization, which refers to ensuring sufficient flexibility in standardized testing conditions to yield the most accurate measurement of proficiency for each examinee.  相似文献   

Can Item Response Times Provide Insight Into Students’ Motivation and Self‐Efficacy in Math? An Initial Application of Test Metadata to Understand Students’ Social–Emotional Needs     

James Soland 《Educational Measurement》2019,38(3):86-96

As computer‐based tests become more common, there is a growing wealth of metadata related to examinees’ response processes, which include solution strategies, concentration, and operating speed. One common type of metadata is item response time. While response times have been used extensively to improve estimates of achievement, little work considers whether these metadata may provide useful information on social–emotional constructs. This study uses an analytic example to explore whether metadata might help illuminate such constructs. Specifically, analyses examine whether the amount of time students spend on test items (after accounting for item difficulty and estimates of true achievement), and difficult items in particular, tell us anything about the student's academic motivation and self‐efficacy. While results do not indicate a strong relationship between mean item durations and these constructs in general, the amount of time students spend on very difficult items is highly correlated with motivation and self‐efficacy. The implications of these findings for using response process metadata to gain information on social–emotional constructs are discussed.  相似文献   

Exploring the use of best-worst scaling to elicit course experience questionnaire responses     

Twan Huybers 《Assessment & Evaluation in Higher Education》2017,42(8):1306-1318

Students are an important stakeholder group in the context of quality assurance in higher education. From their perspective as learners, students’ views on educational experiences are increasingly used as an indicator of educational quality. The Course Experience Questionnaire (CEQ) is a widely used quantitative tool to gauge students’ perceptions of degree programmes. With a view to enhancing the scope for differentiation between individual questionnaire items, this paper explores the use of best–worst scaling to elicit CEQ responses as an alternative to a ratings instrument. The data for this study were generated from a representative sample (n = 263) of graduates from a Dutch university. The survey focused on two core CEQ scales: Good Teaching and Generic Skills. The results show that the Generic Skills items were deemed more pertinent to the degree programme than were the ones related to Good Teaching, with problem-solving skills perceived as the most relevant aspect. Using latent class analysis, six groups of graduates were identified that differed mainly in terms of the relative importance of the skills attributes. Overall, this study shows how the features of best–worst scaling can be used to enhance the scope for discrimination between items in a degree programme evaluation.  相似文献

有限长高分子链特征标度对溶剂性质的依赖性     

张双双  苗兵  所同川 《中国科学院大学学报》2018,35(5):602-606

采用自洽平均场理论并结合蒙特卡洛方法考查不同溶剂中高分子单链回转半径与聚合度的标度关系。计算结果表明,在Θ溶剂中标度指数ν≈0.495,说明此时高分子链遵循理想链的行为;另一方面,在良溶剂中标度指数ν并非普适常数,而是随着溶剂性质的变化而改变,并且总是明显低于经典理论预测值0.6。分析指出,有限链长效应是造成这一偏差的重要原因。  相似文献
