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-This paper describes a new holistic approach to integrate remote and virtual laboratories in the educational process. Aim of the integration is to test students' knowledge not only on lower levels as usual multiple choice tests and the like are doing, but also on higher-order thinking skills. Based on these tests the students should get a detailed feedback about their strengths, weaknesses or misconceptions. Therefore Learning Analytics methods are applied to a database, storing learning activities of the students during their online work-phase in the educational process. The paper discusses the actual approach as well as the architecture of a prototype implementation.

Cable-driven parallel robots offer certain advantages in terms of dynamics and flexibility. They differ significantly in their structure from industrial, serial robots. In this paper we introduce a novel procedure for calibration for a geometrically reconfigurable 3-DoF cable-suspended robot based on inverse kinematics including a pulley for each cable. For that we use a laser tracker with interferometric measurement in combination with local 3D positioning. This is a new approach because of measuring relative laser beam lengths and cable lengths only. In addition the paper introduces a validation procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
