De nieuwe bestuurder

Veel protesten tegen onderwijsvernieuwingen zijn volgens Martens eigenlijk protesten tegen onderwijsbestuurders. Hij onderscheidt daarin twee archetypes: de neoliberale autist en de gevangenbewaarder. Ook schetst Martens een oplossing: "Zorg dat je als baas binding met de werkvloer hebt en weet wat er écht speelt.

Integrating IMS Learning Design and IMS Question and Test Interoperability using CopperCore Service Integration

Retrieved June 30th, 2006, from http://dspace.learningnetworks.orgThis article describes a framework for the integration of e-learning services. There is a need for this type of integration in general, but the presented solution was a direct result of work done on the IMS Learning Design specification (LD). This specification relies heavily on other specifications and ser-vices. The presented architecture is described using the example of two of such services: CopperCore, an LD service and APIS, an IMS Question and Test Interoperability service. One of the design goals of the architecture was to minimize the intrusion for both the services as well as any legacy client that already uses these services.This work has been sponsored by the EU project TENCompetenc

Effects of web-based support for the construction of competence maps.

Stoof, A., Martens, R.L., & Van Merriënboer, J.J.G. (2006). Effects of web-based support for the construction of competence maps. Instructional Science, 34, 189-211Educationalists experience difficulties with the construction of competence maps that describe final attainment levels of educational programs. Web-based support was developed with three supportive aids: A construction kit, a phenomenarium, and an information bank. Each supportive aid was expected to improve perceived process and product quality as well as learning. In a factorial experiment, 266 educational science students constructed a competence map, whether or not supported by each of the three supportive aids. The availability of the construction kit and the phenomenarium had positive effects on perceived process quality and learning. Furthermore, if there was no phenomenarium with example materials, the absence of the construction kit greatly diminished experienced support (i.e., one aspect of process quality); if a phenomenarium was present, the availability of the construction kit had relatively little effect on perceived support. In general, this study indicates that well-designed Web-based support helps to construct competence maps

Detection of static and dynamic activities using uniaxial accelerometers

Rehabilitation treatment may be improved by objective analysis of activities of daily living. For this reason, the feasibility of distinguishing several static and dynamic activities (standing, sitting, lying, walking, ascending stairs, descending stairs, cycling) using a small set of two or three uniaxial accelerometers mounted on the body was investigated. The accelerometer signals can be measured with a portable data acquisition system, which potentially makes it possible to perform online detection of static and dynamic activities in the home environment. However, the procedures described in this paper have yet to be evaluated in the home environment. Experiments were conducted on ten healthy subjects, with accelerometers mounted on several positions and orientations on the body, performing static and dynamic activities according to a fixed protocol. Specifically, accelerometers on the sternum and thigh were evaluated. These accelerometers were oriented in the sagittal plane, perpendicular to the long axis of the segment (tangential), or along this axis (radial). First, discrimination between the static or dynamic character of activities was investigated. This appeared to be feasible using an rms-detector applied on the signal of one sensor tangentially mounted on the thigh. Second, the distinction between static activities was investigated. Standing, sitting, lying supine, on a side and prone could be distinguished by observing the static signals of two accelerometers, one mounted tangentially on the thigh, and the second mounted radially on the sternum. Third, the distinction between the cyclical dynamic activities walking, stair ascent, stair descent and cycling was investigated. The discriminating potentials of several features of the accelerometer signals were assessed: the mean value, the standard deviation, the cycle time and the morphology. Signal morphology was expressed by the maximal cross-correlation coefficients with template signals for the different dynamic activities. The mean signal values and signal morphology of accelerometers mounted tangentially on the thigh and the sternum appeared to contribute to the discrimination of dynamic activities with varying detection performances. The standard deviation of the signal and the cycle time were primarily related to the speed of the dynamic activities, and did not contribute to the discrimination of the activities. Therefore, discrimination of dynamic activities on the basis of the combined evaluation of the mean signal value and signal morphology is propose

Using the Personal Competence Manager as a complementary approach to IMS Learning Design authoring

Vogten, H., Koper, R., Martens, H., & Van Bruggen, J. (2008). Using the Personal Competence Manager as a complementary approach to IMS Learning Design authoring. Interactive Learning Environments, 16(1), 83-100.In this article TENCompetence will be presented as a framework for lifelong competence development. More specifically, the relationship between the TENCompetence framework and the IMS Learning Design (LD) specification is explored. LD authoring has proven to be challenging and the toolset currently available is targeting expert users mostly working for institutions of higher educations. Furthermore these tools re-enforce a fairly rigid top-down workflow approach towards design and delivery. This approach it is not always the most suitable model in all circumstances for all practitioners. TENCompetence provides an alternative bottom-up approach to LD authoring via its first implementation: the Personal Competence Manager (PCM). Constructs such as competence profiles and competence development programmes, let users define, modify, and acquire competences they need for achieving their personal goals. We will show how the PCM provides support for these constructs and stimulates the bottom-up development of learning materials. We will also show how these concepts can be mapped towards LD. This allows the ad hoc designs of the PCM to be captured in a Unit of Learning (UOL). These UOLs can be enhanced and eventually fed back into the PCM, therewith closing the edit cycle. This editing cycle allows for a gradual integration of bottom-up ad hoc designs with more formal top-down designs introducing LD in a gentle fashion.The work on this publication has been sponsored by the TENCompetence Integrated Project that is funded by the European Commission's 6th Framework Programme, priority IST/Technology Enhanced Learning.

The feasibility of posture and movement detection by accelerometry

The discrimination of postures and movements using a minimal set of uniaxial accelerometers was investigated. Postures and movements were distinguished on the bitsis of the high-pm filtered, rectified and low pass filtered signal of one accelerometer. Postures were discriminated by combining the constant valued signals of the accelerometers, mounted on different segments of the body. One sensor mounted ndiully on the trunc and one mounted radially or tangentially on the upper leg appeared to be suficient to discriminate shnding, sitting and lying. Methods are proposed for the discrimination of different cyclical movements
