Latent class models are often used to assign values to categorical variables that cannot be measured directly. This “imputed” latent variable is then used in further analyses with auxiliary variables. The relationship between the imputed latent variable and auxiliary variables can only be correctly estimated if these auxiliary variables are included in the latent class model. Otherwise, point estimates will be biased. We develop a method that correctly estimates the relationship between an imputed latent variable and external auxiliary variables, by updating the latent variable imputations to be conditional on the external auxiliary variables using a combination of multiple imputation of latent classes and the so-called three-step approach. In contrast with existing “one-step” and “three-step” approaches, our method allows the resulting imputations to be analyzed using the familiar methods favored by substantive researchers.  相似文献

We undertook a three-step process to develop, test, and implement a survey research study to identify the models, frameworks, taxonomies, and approaches, most often used by instructional designers to support workplace learning and performance improvement initiatives in a variety of organizational contexts today. A total of 199 professionals working on instructional design, e-learning, and performance improvement projects responded to the survey. They shared the models they use to inform instructional and non-instructional learning interventions, and performance improvement interventions, project work. Our results show the most widely used ID and HPI-related models include: ADDIE, performance gap analysis, Kirkpatrick's evaluation model, Agile development model, rapid ID prototyping model, Merrill's first principles, the behavioral engineering model (BEM), the cognitive load overlay model, ISPI's human performance technology (HPT) process model, and CADDIE. We present implications for program design, course design, and the ensuing choices of study for emerging practitioners working in different contexts.  相似文献

When studying verbal materials, both adults and children are often poor at accurately monitoring their level of learning and regulating their subsequent restudy of materials, which leads to suboptimal test performance. The present experiment investigated how monitoring accuracy and regulation of study could be improved when learning idiomatic phrases. Elementary school children (fourth and sixth-graders) were instructed to predict their test performance by providing judgments of learning (JOLs). They provided JOLs immediately after studying each idiom, after studying all idioms, or after studying all idioms followed by generating sentences in which the idioms were used. Correlations between JOLs and test performance showed that delayed-JOLs and delayed-JOLs with sentence generation were more accurate than immediate JOLs. JOLs after sentence generation also improved regulation of study compared to delayed-JOLs only. Analyses of JOL reaction times suggest that delayed-JOLs led children to retrieve the literal meaning of the idiom, whereas JOLs after sentence generation led children to focus on connections between studied information, contextual information, and prior knowledge. Sentence generation presents a promising method to improve regulation of study, and thus idiom learning.  相似文献

This paper contributes to the debate on institutional diversity in higher education systems by looking at the phenomenon from a comparative (cross‐national) and longitudinal perspective. Despite the attention to diversity in policy debates, surprisingly, only a limited amount of studies address methodological issues. In addition, the number of empirical studies on institutional diversity is low as well. Data on various Western higher education systems are used to illustrate developments in systems' diversity. Furthermore, these data are put in the context of current national (and supranational) policy debates, particularly the role of governments and markets, on maintaining or increasing diversity.  相似文献

The research on worked examples has shown thatfor novices, studying worked examples is oftena more effective and efficient way of learningthan solving conventional problems. Thistheoretical paper argues that addingprocess-oriented information to worked examplescan further enhance transfer performance,especially for complex cognitive skills withmultiple possible solution paths.Process-oriented information refers to theprincipled (``why'') and strategic (``how'')information that experts use when solvingproblems. From a cognitive load perspective,studying the expert's ``why'' and ``how''information can be seen as constituting agermane cognitive load, which can fosterstudents' understanding of the principles of adomain and the rationale behind the selectedoperators, and their knowledge about howexperts select a strategy, respectively. Issueswith regard to the design, implementation, andassessment of effects of process-orientedworked examples are discussed, as well as thequestions they raise for future research.  相似文献

This article explores the opportunities to apply cognitive load theory and four-component instructional design to self-directed learning. Learning tasks are defined as containing three elements: learners must (a) perform the tasks, (b) assess their task performance, and (c) select future tasks for improving their performance. Principles to manage intrinsic and extraneous load for performing learning tasks, such as simple-to-complex ordering and fading-guidance strategies, are also applicable to assessing performance and selecting tasks. Moreover, principles to increase germane load, such as high variability and self-explanation prompts, are also applicable to assessment and selection. It is concluded that cognitive load theory and four-component instructional design provide a solid basis for a research program on self-directed learning.  相似文献
