Higher order thinking skills like analysis, evaluation and synthesis knowledge are difficult to assess in e-learning scenarios. Such skills are usually tested in handson experiments and projects. In the paper we will describe, how we connect our online lab with analytic tools to get data from the learning process during the interaction of the students with the remote lab. Using these data we want to analyze the higher order thinking skills.

Abstract-Based on a grid concept of an interactive hybrid online laboratory we will describe different fields of applications in different learning scenarios. The infrastructure is based on a universal grid concept which guaranties a reliable, flexible as well as robust usage of this online lab. By using the online lab, students are able to design control algorithms with different specification techniques to control electro-mechanical models in the online lab. Additionally, the reconfigurable rapid prototyping platform of the REAL system can be used to test all the taught topics of a given lectures in the field of digital system design. Finally, a special demonstration platform (a ball in a labyrinth on a balance plate) can be used to give the students a better feeling about the possibilities and limitations of remote control and observation via Internet and to evaluate these technologies critically. The implemented online lab infrastructure is based on the iLab architecture of the MIT, which allows to interconnect online labs and to exchange remote lab experiments among different universities worldwide.Index Terms-control engineering education, laboratories, Web-based education, virtual and remote labs, Web-based design tools, distance learning.

A grid concept for reliable, flexible and robust remote engineering laboratories Original published in:International journal of online engineering : IJOE. Abstract-Within this paper, we will describe a grid concept to realize a universal remote lab infrastructure as well as different operation modes based on this concept. This new infrastructure consists of three parts: an internal serial remote lab bus, a bus protection unit to interface the remote lab bus and to protect it from misuse and damage as well as a protection unit, which protects the physical systems (the electro-mechanical models in our remote lab) against deliberate damage or accidentally wrong control commands and which offers different access and control mechanisms. The interconnection between the Web-control units and the selected physical system during a remote lab work session (experiment) as well as the user management is done by the lab server, which also handles the webcams. The implemented remote lab infrastructure is based on the iLab architecture of the MIT, which allows to interconnect remote labs and to exchange remote lab experiments among different universities worldwide.Index Terms-control engineering education, laboratories, Web-based education, virtual and remote labs, Web-based design tools, distance learning.

Abstract. This paper describes a universal remote lab infrastructure. This new extended infrastructure consists of three parts: a control unit for performing practical experiments with the physical systems, located in our remote lab, a bus protection unit to interface the remote lab bus and to protect it from misuse and damage, as well as a protection unit, which protects the physical systems against deliberate damage or accidentally wrong control commands. These units are for control, interface, surveillance and protection of the connected physical systems. The general concept and setup is presented in this paper, including the possibilities and limitations of such an approach. This concept is an extension of the remote lab architecture proposed in earlier papers.
