This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals ("if") and disjunctions ("or"), unlike those in logic, refer to conjunctions of epistemic…

All reviews are selective and this one restricts itself to content analysis of articles published between the beginning of 2005 and the end of 2014 in the premier, generalist, Science-education, research journals: International Journal of Science Education; Journal of Research in Science Teaching; Research in Science Education; Science Education,…

The Enhanced Virtual Laboratory (EVL) is the product of a Department of Defense grant to enhance outreach, research, and education for cyber security. Through web-based laboratories, EVL allows users to remotely experience interactive content with virtual machines inside a modern web browser providing constructivism-based, student-centered,…

This study was conducted to analyze potential item parameter drift (IPD) impact on person ability estimates and classification accuracy when drift affects an examinee subgroup. Using a series of simulations, three factors were manipulated: (a) percentage of IPD items in the CAT exam, (b) percentage of examinees affected by IPD, and (c) item pool…

The belief, which includes the ability of doing something effectively, is self-efficacy. In this study, effective learning were intended to provide the participants, by using simulation and micro-teaching techniques from current method and approaches considering internationals standarts in growing school leaders. In this context, the purpose of…

Extension educators should think of themselves as change agents, yet many act as information dispensers. Accordingly, we sought to determine whether we could change perceptions of county Extension educators in Oklahoma regarding their function as change agents. Educators participated in a two-part (two-treatment) professional development…

The need for youth credit card education is clear given the many statistics indicating increasing credit card debt and an overall scarcity of credit card education targeting youths. The Teen$ Credit Card simulation program offers youths an opportunity to experience "owning" a credit card, using it, and realizing the consequences of…

Bayesian item response theory (IRT) modeling stages include (a) specifying the IRT likelihood model, (b) specifying the parameter prior distributions, (c) obtaining the posterior distribution, and (d) making appropriate inferences. The latter stage, and the focus of this research, includes model criticism. Choice of priors with the posterior…

The importance of increasing interest in the STEM disciplines has been noted in a number of recent national reports. While many previous studies have focused on such efforts inside of the formal classroom, comparatively few have looked closely at informal learning environments. We investigate the innovative use of technology in informal learning…

Two professors of education discuss their experiences using a virtual reality program to help preservice teachers gain classroom management skills. They say the platform provides an authentic-and convenient--environment in which education students can develop their practice and gain confidence without making mistakes with real students.

Context: Postprofessional athletic training programs continue to prepare advanced-practice leaders in the profession. As part of being leaders and clinical scholars within the field, it is important that students pursing postprofessional graduate education be exposed to curriculum and instructional theory, practice, and strategies. Objective: To…

It was aimed in this study to determine the teacher candidates' views on the augmented reality applications in education. It is a descriptive study to identify the present situation. Survey model, one of the quantitative research methods, was used in the research. The sample group of the study is comprised of 220 teacher candidates who are…

This paper serves as a practical guide to mediation design and analysis by evaluating the ability of mediation models to detect a significant mediation effect using limited data. The cross-sectional mediation model, which has been shown to be biased when the mediation is happening over time, is compared to longitudinal mediation models:…

This study proposes a novel e-learning system that can be used as a comprehensive learning resource for electronic circuits, covering design, theoretical analysis, and circuit construction experiments. The proposed system uses an automated recognition technique for schematic symbols that are handwritten on a touchscreen of a mobile tablet-type…

Engagement and motivation are ones of the main factors that impact the student performance during a learning process. The reason why, introducing Gamification in learning aims to improve the learning process, by making use of the motivating effects of digital game elements and techniques. However, summarizing Gamification into a set of technical…
