Automated tutoring for a database skills training environment

Universities are increasingly offering courses online. Feedback, assessment, and guidance are important features of this online courseware. Together, in the absence of a human tutor, they aid the student in the learning process. We present a programming training environment for a database course. It aims to offer a substitute for classroom based learning by providing synchronous automated feedback to the student, along with guidance based on a personalized assessment. The automated tutoring system should promote procedural knowledge acquisition and skills training. An automated tutoring feature is an integral part of this tutoring system

Automated tutoring for a database skills training environment

The emergence of educational technology and the growth of the Internet, coupled with the rise in the number of students entering third level education, has led to a surge of online courses offered by universities. These online courses may be part of a traditional classroom based course, or they may act as an entire course by themselves. Student engagement, assessment, feedback and guidance are important parts of any course, but have an added importance for one that is presented online. Together, in the absence of a human tutor, they can greatly aid the student in the learning process. We present an automated skills training system for a database programming environment that will promote procedural knowledge acquisition and skills training. An SQL (Structured Query Language) select statement tutoring tool is an integral part of this. Targeted at students with a prior knowledge of database theory, and as part of a blended learning strategy, the system allows the student to practice SQL querying at his own time and pace. This is achieved by providing pedagogical actions that would be offered by a human tutor. Specifically, we refer to synchronous feedback and guidance based on a personalised assessment. Each of these features is automated and includes a level of personalisation and adaptation. A high-level of interaction and engagement exists between the student and the system. Students assume control of their learning experience

Dickerson v. United States preserves the status quo regime for judicial oversight of police interrogation. That result could be seen, in the present climate, as a victory for due process values, but there remain many reasons for concern that existing safeguards are flawed - that they are either too restrictive or not restrictive enough. Such concerns are partly empirical, of course. They depend on factual assessments of how much the Miranda rules do restrict the police. But such concerns also reflect a crucial, though often unstated, normative premise; they presuppose a certain view of how much the police should be restricted. To evaluate the Miranda safeguards and determine whether they should be replaced by some other regime, it is essential to focus first on that normative premise. And for present purposes I will restrict myself to its constitutional dimension. I will focus on a surprisingly neglected question - that of determining which restrictions on police interrogation are mandated by ordinary Fifth Amendment principles. My thesis is that the Court, even as it reaffirmed Miranda, perpetuated an extraordinarily confusing and illogical notion of what the Fifth Amendment means. Both the Court\u27s majority in Dickerson and its dissenters share a conception of the Fifth Amendment that can be right only if the constitutional principles governing police interrogation differ from those that determine Fifth Amendment compulsion in every other setting. In other words, the Court (and all its Justices) apparently accept a kind of Fifth Amendment exceptionalism, under which the standards applicable to police interrogation are kept distinct from the standards applicable to all other official questioning of witnesses and suspected offenders

A hybrid method for the analysis of learner behaviour in active learning environments

Software-mediated learning requires adjustments in the teaching and learning process. In particular active learning facilitated through interactive learning software differs from traditional instructor-oriented, classroom-based teaching. We present behaviour analysis techniques for Web-mediated learning. Motivation, acceptance of the learning approach and technology, learning organisation and actual tool usage are aspects of behaviour that require different analysis techniques to be used. A hybrid method based on a combination of survey methods and Web usage mining techniques can provide accurate and comprehensive analysis results. These techniques allow us to evaluate active learning approaches implemented in form of Web tutorials

Personalised correction, feedback, and guidance in an automated tutoring system for skills training

In addition to knowledge, in various domains skills are equally important. Active learning and training are effective forms of education. We present an automated skills training system for a database programming environment that promotes procedural knowledge acquisition and skills training. The system provides support features such as correction of solutions, feedback and personalised guidance, similar to interactions with a human tutor. Specifically, we address synchronous feedback and guidance based on personalised assessment. Each of these features is automated and includes a level of personalisation and adaptation. At the core of the system is a pattern-based error classification and correction component that analyses student input

Model-driven description and validation of composite learning content

Authoring of learning content for courseware systems is a complex activity requiring the combination of a range of design and validation techniques. We introduce the CAVIAr courseware models allowing for learning content description and validation. Model-based representation and analysis of different concerns such as the subject domain, learning context, resources and instructional design used are key contributors to this integrated solution. Personalised learning is particularly difficult to design as dynamic configurations cannot easily be predicted and tested. A tool-supported technique based on CAVIAr can alleviate this complexity through the validation of a set of pedagogical and non-pedagogical requirements. Courseware validation checks intra- and inter-content relationships and the compliance with requirements and educational theories

Utilising ontology-based modelling for learning content management

Learning content management needs to support a variety of open, multi-format Web-based software applications. We propose multidimensional, model-based semantic annotation as a way to support the management of access to and change of learning content. We introduce an information architecture model as the central contribution that supports multi-layered learning content structures. We discuss interactive query access, but also change management for multi-layered learning content management. An ontology-enhanced traceability approach is the solution

A conceptual architecture for interactive educational multimedia

Learning is more than knowledge acquisition; it often involves the active participation of the learner in a variety of knowledge- and skills-based learning and training activities. Interactive multimedia technology can support the variety of interaction channels and languages required to facilitate interactive learning and teaching. A conceptual architecture for interactive educational multimedia can support the development of such multimedia systems. Such an architecture needs to embed multimedia technology into a coherent educational context. A framework based on an integrated interaction model is needed to capture learning and training activities in an online setting from an educational perspective, to describe them in the human-computer context, and to integrate them with mechanisms and principles of multimedia interaction

Intelligent and adaptive tutoring for active learning and training environments

Active learning facilitated through interactive and adaptive learning environments differs substantially from traditional instructor-oriented, classroom-based teaching. We present a Web-based e-learning environment that integrates knowledge learning and skills training. How these tools are used most effectively is still an open question. We propose knowledge-level interaction and adaptive feedback and guidance as central features. We discuss these features and evaluate the effectiveness of this Web-based environment, focusing on different aspects of learning behaviour and tool usage. Motivation, acceptance of the approach, learning organisation and actual tool usage are aspects of behaviour that require different evaluation techniques to be used
