Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com
In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback. 相似文献

Against the backdrop of Spain’s Transparency Act, this article discusses the presence or otherwise of a series of document types, proposed as management-related transparency indicators, on 61 (8 national and 53 provincial) historic archive websites. Although examples of good practice were identified, the information provided was found to be scant, in particular as regards lines of action, organisational objectives and yearly reports. The information most commonly provided on the websites included the collection classification chart, service use regulations and citizen charters. The inference drawn was that archives, so intently focused on their role in the application of the Act by the organisations they serve, neglect their own administrative obligations in respect of its provisions. The recommendation is that as government-funded and subsidised public service institutions, historic archives should exercise transparency by furnishing the information stipulated in the Act on their websites. 相似文献

In the United States, how to provide a high-quality education to all students has been a focal discussion, especially in urban settings. One potential solution that has emerged to confront this issue involves urban teacher residency (UTR) programs that provide innovations concerning the recruitment, preparation, and retention of teachers in high-need urban schools. In this study, we conducted a content analysis and compared steering documents of a UTR program in California with materials from a teacher-training program in Finland. Despite differences in both the legislative and local contexts under which the two programs operate, we found many similarities in both the steering documents and course offerings of these two teacher-training programs. For example, both promote aspects of social justice and are research-based. Furthermore, both offer a variety of types of courses, such as those emphasizing the pedagogical bases of education and research studies in education.

Many educators believe that the goal of equity is far from being achieved given the dilemmas faced by today's inner city public schools. The authors examine the potential of Temple University's Professional Development School Partnership, a collaborative project with the School District of Philadelphia, to facilitate educational equity within an urban center. Current understandings of the construct of equity are identified and used to explore the possibilities and challenges of striving for equity in the urban center. The development of this partnership documents growth into a more inclusive, expansive, and collaborative style of working together. A closer look into this process is provided by an in-depth discussion of two essential components of the partnership, namely, its culturally responsive process and its objective of transforming the teaching and learning conditions of schools. It is argued that school systems need to look critically at their own educational resources as well as policies and practices to guarantee that they genuinely promote participation and achievement of all students. In essence we contend that there cannot be equity without the assurance that students will achieve to their fullest potential. 相似文献

To better understand the statistical properties of the deterministic inputs, noisy “and” gate cognitive diagnosis (DINA) model, the impact of several factors on the quality of the item parameter estimates and classification accuracy was investigated. Results of the simulation study indicate that the fully Bayes approach is most accurate when the prior distribution matches the latent class structure. However, when the latent classes are of indefinite structure, the empirical Bayes method in conjunction with an unstructured prior distribution provides much better estimates and classification accuracy. Moreover, using empirical Bayes with an unstructured prior does not lead to extremely poor results as other prior-estimation method combinations do. The simulation results also show that increasing the sample size reduces the variability, and to some extent the bias, of item parameter estimates, whereas lower level of guessing and slip parameter is associated with higher quality item parameter estimation and classification accuracy. 相似文献

Comparative analysis of expectancies of efficacy in in-service and prospective teachers 总被引：1，自引：0，他引：1
This study examines the beliefs about effective teaching in student teachers and inservice teachers. We constructed a measurement composed of an adaptation in Spanish of the Gibson and Dembo's (1984. Teacher efficacy: A construct validation. Journal of Educational Psychology, 76, 569–582). Teacher Efficacy Scale and of the items included in Emmer and Hickman's (1991. Teacher efficacy in classroom management and discipline. Educational and Psychological Measurement, 51, 755–765) “classroom management/discipline efficacy” dimension. A total of 339 participants took part in the study. The factor analysis carried out of the results obtained showed three principal factors: classroom management/discipline efficacy, personal teaching efficacy and general teaching efficacy. Analyses which compared efficacy expectancies showed significant differences in the management and discipline dimension in favour of the group of working teachers, whereas an opposite pattern emerged in the general teaching dimension. In addition, there were differences in the management/discipline dimension in terms of the number of years’ experience in the group of inservice teachers. The interpretation of the results is expressed in terms of the Bandura's perceived self-efficacy theory. We also indicate some implications that the analysis of these expectancies may have for the training and professional development of teachers, and we suggest lines for future research. 相似文献

Automatic evaluation is a challenging field that has been addressed by the academic community in order to reduce the assessment workload. In this work we present a new element for the authoring tool Easy Java Simulations (EJS). This element, which is named automatic evaluation element (AEE), provides automatic evaluation to virtual and remote laboratories built with EJS by using the server application Goodle grading management system (GMS). The integration of both tools entitles a professor to create interactive virtual and remote laboratories and automatically evaluate the work of their students. As a test bed two case studies are presented; a non-linear controller design virtual laboratory used in an advanced control master course and a servomechanism virtual laboratory used in an undergraduate basic control course. 相似文献

Analyzing examinees’ responses using cognitive diagnostic models (CDMs) has the advantage of providing diagnostic information. To ensure the validity of the results from these models, differential item functioning (DIF) in CDMs needs to be investigated. In this article, the Wald test is proposed to examine DIF in the context of CDMs. This study explored the effectiveness of the Wald test in detecting both uniform and nonuniform DIF in the DINA model through a simulation study. Results of this study suggest that for relatively discriminating items, the Wald test had Type I error rates close to the nominal level. Moreover, its viability was underscored by the medium to high power rates for most investigated DIF types when DIF size was large. Furthermore, the performance of the Wald test in detecting uniform DIF was compared to that of the traditional Mantel‐Haenszel (MH) and SIBTEST procedures. The results of the comparison study showed that the Wald test was comparable to or outperformed the MH and SIBTEST procedures. Finally, the strengths and limitations of the proposed method and suggestions for future studies are discussed. 相似文献

The aim of this research was to determine whether the new geographic information technologies, included as teaching objectives in the new European Space for Higher Education Engineering degrees, develop spatial abilities. Bearing this in mind, a first year seminar using the INSPIRE Geoportal (Infrastructure for Spatial Information in Europe) was designed, involving 46 engineering students from the University of La Laguna. The spatial orientation ability development was analysed through statistical inference methods, using the Perspective Taking/Spatial Orientation Test. 相似文献
