Diagnosing Teachers’ Understandings of Rational Numbers: Building a Multidimensional Test Within the Diagnostic Classification Framework     

Laine Bradshaw  Andrew Izsák  Jonathan Templin  Erik Jacobson 《Educational Measurement》2014,33(1):2-14

We report a multidimensional test that examines middle grades teachers’ understanding of fraction arithmetic, especially multiplication and division. The test is based on four attributes identified through an analysis of the extensive mathematics education research literature on teachers’ and students’ reasoning in this content area. We administered the test to a national sample of 990 in‐service middle grades teachers and analyzed the item responses using the log‐linear cognitive diagnosis model. We report the diagnostic quality of the test at the item level, mastery classifications for teachers, and attribute relationships. Our results demonstrate that, when a test is grounded in research on cognition and is designed to be multidimensional from the onset, it is possible to use diagnostic classification models to detect distinct patterns of attribute mastery.  相似文献

On Equivalence of Public Sign Translation from the Perspective of the Relevance Theory     

张靖  杨萌 《读与写:教育教学刊》2011,(5):1-5

At present,with the development of the city culture and globalization,bilingual signs are more widely used in the society.Among the public sign translations,there are many successful examples.But,at the same time,many problems such as mistranslation and poor translation widely exist in the process of promotion of city culture.The relevance theory interprets translation from the original author’s and translator’s cognitive surroundings,thus bringing a new approach for translation,especially for applied text translation.Based on the previous study,the author analyzes the equivalent effect of sign translation from the perspective of the relevance theory and summarizes some principles and strategies for public sign translation,in hope of helping the promotion of the city image and culture.  相似文献

Influence of Magnetic Field on the Rectification Process of Binary Heterogeneous Azeotrope     

贾绍义  吴松海李真 贾亮 《天津大学学报(英文版)》2005,11(4):240-244

To improve separate effect of binary heterogeneous azeotrope in the magnetic field with different magnetic induction intensity, the influence of magnetic field on the rectification process of binary heterogeneous azeotrope was investigated with l-butanol-water system. The results show that the composition of liquid-liquid phase equilibrium of l-butanol-water system has definitely changed, the composition of l-butanol in light phase （l-butanol layer） increases by 1. 17%-1.63% and the composition of water in heavy phase （water layer） increases by 1.21%-1.58% under the influence of magnetic field. By separation of magnetization, the composition of l-butanol increases by 0.8%-1.2% and the recovery ratio of 1 -butanol increases by 1.6%-2.5%. Magnetic field has positive effect, however, the magnetized effect is not in proportion to magnetic induction intensity and has an optimum condition, in the range of 0.25 T-0. 3 T.  相似文献   

Structuring Occasions     

Jo Towers  Brent Davis 《Educational Studies in Mathematics》2002,49(3):313-340

Within the mathematics education literature, the term constructivism has been subject to a diversity of interpretations, many of which are trivializations of original theoretical work. We suggest that trivialized versions of constructivism continue to be promulgated due, in large part,to misunderstandings of some of the vocabulary adopted by its advocates. This situation has been the source of considerable frustration in our ongoing efforts to communicate the insights and implications of radical and social constructivist theories to preservice and practicing teachers. We discuss some of the specifics of these frustrations along with strategies intended to flag and circumvent them in our work with teachers. The writing is structured around a set of recursively elaborated interpretations of a classroom episode. Developed around varied understandings of the terms structure and construct, these interpretations are intended to show how we have worked with teachers to foster a deep appreciation of how learning might be reframed as dependent on, rather than determined by, teaching.This revised version was published online in September 2005 with corrections to the Cover Date.  相似文献   

How student perceptions about online learning difficulty influenced their satisfaction during Canada's Covid-19 response     

Colin Conrad  Qi Deng  Isabelle Caron  Oksana Shkurska  Paulette Skerrett  Binod Sundararajan 《British journal of educational technology : journal of the Council for Educational Technology》2022,53(3):534-557

The COVID-19 pandemic has posed a significant challenge to higher education and forced academic institutions across the globe to abruptly shift to remote teaching. Because of the emergent transition, higher education institutions continuously face difficulties in creating satisfactory online learning experiences that adhere to the new norms. This study investigates the transition to online learning during Covid-19 to identify factors that influenced students' satisfaction with the online learning environment. Adopting a mixed-method design, we find that students' experience with online learning can be negatively affected by information overload, and perceived technical skill requirements, and describe qualitative evidence that suggest a lack of social interactions, class format, and ambiguous communication also affected perceived learning. This study suggests that to digitalize higher education successfully, institutions need to redesign students' learning experience systematically and re-evaluate traditional pedagogical approaches in the online context.

Practitioner notes

What is already known about this topic

• University transitions to online learning during the Covid-19 pandemic were undertaken by faculty and students who had little online learning experience.
• The transition to online learning was often described as having a negative influence on students' learning experience and mental health.
• Varieties of cognitive load are known predictors of effective online learning experiences and satisfaction.

What this paper adds

• Information overload and perceptions of technical abilities are demonstrated to predict students' difficulty and satisfaction with online learning.
• Students express negative attitudes towards factors that influence information overload, technical factors, and asynchronous course formats.
• Communication quantity was not found to be a significant factor in predicting either perceived difficulty or negative attitudes.

Implications for practice and/or policy

• We identify ways that educators in higher education can improve their online offerings and implementations during future disruptions.
• We offer insights into student experience concerning online learning environments during an abrupt transition.
• We identify design factors that contribute to effective online delivery, educators in higher education can improve students' learning experiences during difficult periods and abrupt transitions to online learning.

Latent Variable Modeling and Adaptive Testing for Experimental Cognitive Psychopathology Research     

Michael L. Thomas  Gregory G. Brown  Virginie M. Patt  John R. Duffy 《Educational and psychological measurement》2021,81(1):155

The adaptation of experimental cognitive tasks into measures that can be used to quantify neurocognitive outcomes in translational studies and clinical trials has become a key component of the strategy to address psychiatric and neurological disorders. Unfortunately, while most experimental cognitive tests have strong theoretical bases, they can have poor psychometric properties, leaving them vulnerable to measurement challenges that undermine their use in applied settings. Item response theory–based computerized adaptive testing has been proposed as a solution but has been limited in experimental and translational research due to its large sample requirements. We present a generalized latent variable model that, when combined with strong parametric assumptions based on mathematical cognitive models, permits the use of adaptive testing without large samples or the need to precalibrate item parameters. The approach is demonstrated using data from a common measure of working memory—the N-back task—collected across a diverse sample of participants. After evaluating dimensionality and model fit, we conducted a simulation study to compare adaptive versus nonadaptive testing. Computerized adaptive testing either made the task 36% more efficient or score estimates 23% more precise, when compared to nonadaptive testing. This proof-of-concept study demonstrates that latent variable modeling and adaptive testing can be used in experimental cognitive testing even with relatively small samples. Adaptive testing has the potential to improve the impact and replicability of findings from translational studies and clinical trials that use experimental cognitive tasks as outcome measures.  相似文献
