BACKGROUND Existing theories of self-directed learning (SDL) have emphasized the importance of process, personal, and contextual factors. Previous medical education research has largely focused on the process of SDL. We explored the experience with and perception of SDL among internal medicine residents to gain understanding of the personal and contextual factors of SDL in graduate medical educ...

This tutorial is a quick introduction to the basic ideas, concepts and features of SDL. It starts by introducing the class of systems that SDL is intended for and the main features of their behaviour. The correspondence between these features and the basic concepts of SDL are explained. Then the various language elements of SDL are introduced gradually and exemplified by way of a simple system ...

BACKGROUND Existing literature is mixed as to whether self-directed learning (SDL) delivers improvements in knowledge, skills or attitudes of medical students compared with traditional learning methods. This study aimed to determine whether there is an association between engagement in SDL and student performance in clinical examinations, the factors that influence student engagement with SDL i...

Distributed systems evolution has led telecommunication management network (TMN) systems to use object-oriented middleware paradigm, mainly CORBA (Common Object Request Broker Architecture). CORBA only includes a mechanism for defining object interfaces not for specifying the behaviour of these objects. The behaviour of a TMN system has to follow concrete and restrictive specifications, which a...

The paper describes an abstract implementation of SDL communication semantics in the larger context of a design of SDL 92 simulation and veriication tools. SDL signal exchange involves routing for signal traac that allows for nondeterminism in communication path selection. The communication path selected may additionally be subject to a path constraint using SDL's via construct. We describe rst...

SDL claims to be a language for the description of open systems, allowing the integration of other components into an SDL system and that of an SDL system as a mere component into a greater unit. Indeed, SDL provides the possibility for the interaction of a system with its environment. Signals can be exchanged with the environment and in addition the developer may hide arbitrary actions inside ...

The Co-design is the process of generating a mixed hardware/software architecture starting from system-level model. This paper discusses the uses of SDL for the co-design of an ATM Network Interface Card (NIC). In this study, the initial specification is given in SDL. The architecture generation is made using Cosmos, a co-design tool for multiprocessor architecture. Several architectures are pr...

Today, SDL and SystemC are two very popular languages for embedded systems modeling. SDL has specific advanced features that make it good for reflection of the multi-object systems and interactions between modules. It is also good for system model validation. The SystemC models are better suitable for tracing internal functions of the modeled modules. The hypothetical possibility of combined us...

Self-Directed Learning (SDL) in Massive Open Online Courses (MOOC) is gaining interest, as online learning is increasingly learner-centred and autonomous. Most SDL research starts from the premise that SDL happens more frequently in connectivism MOOC (cMOOC) than in the more instructor-led MOOCs. In this study the authors look at SDL experiences from learners enrolled in two MOOC courses during...

Over the course of several years working with many diverse projects using SDL for the design of commercial products, we have developed several practical guidelines related to creating SDL models for deployment. This paper discusses the SDL modeling guidelines, covering general recommendations, specific details about using SDL modeling features, performance considerations, platform interface con...
