Objectives. The purpose of this study is to reveal the importance of informatics in continuing vocational education in Germany. The labour market is a field with diverse data structures and multiple applications, for example connecting jobseekers and ...

In recent years, learning process data have become increasingly easy to collect through computer-based learning environments. This has led to increased interest in the field of learning analytics, which is concerned with leveraging learning process data ...

We describe a method for analyzing student data from online programming exercises. Our approach uses contingency tables that combine whether or not a student answered an online exercise correctly with the number of attempts that the student made on that ...

Analyzing the process data of students as they complete programming assignments has the potential to provide computing educators with insights into both their students and the processes by which they learn to program. In prior research, we explored the ...

Systematic endeavors to take computer science (CS) and computational thinking (CT) to scale in middle and high school classrooms are underway with curricula that emphasize the enactment of authentic CT skills, especially in the context of programming in ...

Learning computing with respect to the context of its use has been linked in previous reports to student motivation in introductory Computer Science (CS) courses. In this report, we consider the role of context in a second course. We present a case ...

This article presents a project-based case study that was developed for students with diverse backgrounds and varied inclinations for engaging technical topics. The project, called History Places, requires that student teams develop a vision for a kind ...

Many introductory courses to cryptology and computer security start with or include a discussion of classical ciphers that usually contemplates some cryptanalysis techniques used to break them. Ganzúa (picklock in Spanish) is an application designed to ...

Advances in computer and Internet technologies have made it more and more important for information technology professionals to acquire experience in a variety of aspects, including new technologies, system integration, database administration, and ...

Ada/Mindstorms 2.0 is an Ada interface to the Lego RCX "brick," included as part of the Lego Mindstorms™ Robotics Invention System. Programs are written with an Ada compiler, translated into Dave Baum's Not Quite C language (NQC), then recompiled and ...

Active learning is an effective learning approach. In this article we present an intelligent agent-assisted environment for active learning to better support the student-centered, selfpaced, and highly interactive learning approach. The environment uses ...

Many educational resources and objects have been developed as Java applets or applications, which can accessed by simply downloading them from various repositories. It is often necessary to share these resources in real time, for instance when an ...

This article describe the use of dedicated ontology for teaching in the context of the L³ project, a national joint project for deploying further vocational education in Germany. The requirements for the open L³ learning infrastructure are presented in ...

In the last few years the (semi-) automatic sequencing of course material has become an important research issue, particularly the standardization of metadata for educational resources. Sequencing can help to generate hypermedia documents which, at ...

The production of interactive multimedia content is in most cases an expensive task in terms of time and cost. Hence, optimizing production by exploiting the reusability of interactive multimedia elements is mandatory. Reusability can be triggered by a ...

Computer networks and distribute systems are characterized by highly dynamic, concurrent, and complex processes. Thus, training in this area requires great effort from both teachers and learners. Teachers are disatisfied with available methods for ...
