In order to meet the needs of today's knowledge economy, education needs to move beyond the industrial age approach of treating all learners as if they are the same and adopt a learner-centered model of education suitable for the information age. To support this model, a new and transformative technology is needed that focuses on mastery and customized learning. This article reviews the existing approaches to educational technology before proposing a new, customizable, open, and interoperable technology: a personalized integrated educational system (PIES) that provides full functionality for students, teachers, parents and other stakeholders and bridges the gaps between formal and informal learning. PIES' four primary functions: record keeping, planning, instruction, and assessment, as well as secondary functions, are defined and described. Future challenges and research opportunities are also identified. 相似文献

This study examines the effects of the activity of building systems models for school-based problems on problem solving and on conceptual change in elementary science classes. During a unit on the water cycle in an Asian elementary school, students constructed systems models of the water cycle. We found that representing ill-structured problems as system models improves problem solving as well as creating beneficial conceptual change related to the topic. 相似文献

Traditionally, internships have provided a unique way for criminal justice students to gain work experience while earning academic credit. Questions remain, however, as to whether a student's educational experiences adequately reflect the realities of internship (and other work-related) experiences. As part of a larger study, we sought to explore student views and attitudes regarding their undergraduate curriculum and its relevance to their experiences at the criminal justice agencies. Through the use of self-report surveys, findings were two-fold, indicating tremendous support for internship programs. Moreover, (1) students felt their undergraduate curricula adequately reflected the practical realities of criminal justice operations, and (2) internships were regarded as invaluable in preparing students for criminal justice careers. 相似文献

In longitudinal studies, investigators often measure multiple variables at multiple time points and are interested in investigating individual differences in patterns of change on those variables. Furthermore, in behavioral, social, psychological, and medical research, investigators often deal with latent variables that cannot be observed directly and should be measured by 2 or more manifest variables. Longitudinal latent variables occur when the corresponding manifest variables are measured at multiple time points. Our primary interests are in studying the dynamic change of longitudinal latent variables and exploring the possible interactive effect among the latent variables. Much of the existing research in longitudinal studies focuses on studying change in a single observed variable at different time points. In this article, we propose a novel latent curve model (LCM) for studying the dynamic change of multivariate manifest and latent variables and their linear and interaction relationships. The proposed LCM has the following useful features: First, it can handle multivariate variables for exploring the dynamic change of their relationships, whereas conventional LCMs usually consider change in a univariate variable. Second, it accommodates both first- and second-order latent variables and their interactions to explore how changes in latent attributes interact to produce a joint effect on the growth of an outcome variable. Third, it accommodates both continuous and ordered categorical data, and missing data. 相似文献

This article presents a practitioner's funding model indicative of the primary revenue streams of community colleges in Texas. Methodology is developed to identify internal and external processes for the comparison of these primary revenue streams on a per-contact-hour basis. Student tuition, ad valorem property tax, maintenance taxing district, and state appropriation revenues are analyzed to provide a framework for the subsequent development of methodologies to identify disparities in the Texas community college funding mechanism. 相似文献

The analysis of interaction among latent variables has received much attention. This article introduces a Bayesian approach to analyze a general structural equation model that accommodates the general nonlinear terms of latent variables and covariates. This approach produces a Bayesian estimate that has the same statistical optimal properties as a maximum likelihood estimate. Other advantages over the traditional approaches are discussed. More important, we demonstrate through examples how to use the freely available software WinBUGS to obtain Bayesian results for estimation and model comparison. Simulation studies are conducted to assess the empirical performances of the approach for situations with various sample sizes and prior inputs. 相似文献

As a native Korean and specialist in the field of Early Childhood Education, I concur with the current state of our teacher education programs as presented by Eunhye Park Han. Having said this, I would like to raise yet another issue, however, relating to the proposal for extending the student teaching experience. It was pointed out in the article that the four weeks of student teaching currently required are not sufficient for gaining practical knowledge. Let us suppose that the requirement is changed and a longer period of field experience is required. Will a longer period of practical work necessarily result in a teacher with greater competence? Two years ago, I conducted a study in a 4-year-old classroom in a university-based kindergarten in Korea. I was amazed to see a teacher who was handling more than 30 children, with no additional adult in the classroom. 相似文献

Resident assistants (RAs) can serve as important suicide prevention gatekeepers. The purpose of the study was to determine if training improved RAs’ crisis communications skills and suicide‐related knowledge and to determine if the knowledge elements predicted crisis communications skills. New RAs showed significant improvement in all areas from pretest to posttest, whereas returning RAs showed no significant increase in any of the areas. None of the knowledge areas predicted communications skills for either group. 相似文献
