In this paper, the author reports findings from research concerning the planning of learning scenarios in education. The purpose of the research is to explore the value of this scenario planning and reflection-on-action. In particular, the research objective is to explore how this innovative method can guide the adoption of ICT in education and cultivate competencies for lifelong and lifewide l...

We present a new analysis of the problem of learning with drifting distributions in the batch setting using the notion of discrepancy. We prove learning bounds based on the Rademacher complexity of the hypothesis set and the discrepancy of distributions both for a drifting PAC scenario and a tracking scenario. Our bounds are always tighter and in some cases substantially improve upon previous o...

background: problem-based learning (pbl) is one of the most commonly used educational methods in medical schools of different countries. by working through this method, students think critically, generate ideas, and acquire the knowledge and skills required to become a doctor. objectives: this study aimed to compare problem-based learning with lecture-based learning in the education of medical ...

I the context of multistage stochastic optimization problems, we propose a hybrid strategy for generalizing to nonlinear decision rules, using machine learning, a finite data set of constrained vector-valued recourse decisions optimized using scenario-tree techniques from multistage stochastic programming. The decision rules are based on a statistical model inferred from a given scenario-tree s...

background and purpose: determined outcomes in education are based on the ultimate expectations from the medical graduates. methods: one hundred and two medical school graduates of the last 4 years of universities located in a city were asked in 2015 to self-evaluate themselves according to 42 expected skill outcomes. these 42 procedures were approved in 2007, by expert panels of iranian minist...

background: in the present study, we studied the clinical students’ viewpoints toward traditional and case study training methods. methods: this analytical descriptive study was conducted in cardiac ward of valiasr hospital in birjand from 1389 to 1390. 5 training sessions in the form of case presentation were held during a one-month course in cardiac ward. the trainer prepared a powerpoint fil...

Background: Co- word analysis is one of the content analysis methods used in scientometric studies and mapping the scientific structure of various fields. The purpose of the present research is to map the structure of distance education using the co-word analysis. Methods: The research method is content analysis using co- word analysis. The research population are 31607 documents indexed in the...

Interactive features denote one of the most important surplus values of e-learning. In the scientific discussion interaction and interactivity are distinguished. Numerous options are available to enhance interaction and interactivity in elearning. In this contribution we report on an e-learning project that tries to implement interaction and interactivity using a blended-learning scenario which...

Selecting appropriate learning services for a learner from a large number of heterogeneous knowledge sources is a complex and challenging task. This article illustrates and discusses how Semantic Web technologies such as RDF and ontology can be applied to e-learning systems to help the learner in selecting an appropriate learning course or retrieving relevant information. It presents the main f...
