Performance assessment as a diagnostic tool for science teachers

Assessment of the thermal performance of holistic flat roof systems of industrial buildings

The thermal performance of conventional flat roof systems is in practice normally assessed by the heat transfer caused by conduction. The effects of radiation and convection are in such cases ignored as being insignificant. Holistic flat roof systems are designed to better utilize the impact of radiation and convection on improving the indoor climate. However, to determine the influence of radiation and convection, an integrated assessment should be used. In this article, the effect of applying five different holistic flat roof systems is compared with a conventional roof system of an existing storage hall. With EnergyPlus the internal air temperature in the storage hall was simulated for a complete year using weather data of the moderate Dutch climate. The most efficient systems prove to be the systems that decrease the heat gain by solar radiation. These systems can decrease the number of overheating hours by up to 95%. Increasing the thermal resistance value of a roof could lead to adverse results. The study shows an integrated approach that could be implemented in policies and regulations for the thermal assessment of holistic flat roof systems

Performance of Electric Vehicle Charging Infrastructure: Development of an Assessment Platform Based on Charging Data

Developers of charging infrastructure, be it public or private parties, are highly dependent on accurate utilization data in order to make informed decisions where and when to expand charging points. The Amsterdam University of Applied Sciences, in close cooperation with the municipalities of Amsterdam, Rotterdam, The Hague, Utrecht, and the Metropolitan Region of Amsterdam Electric, developed both the back- and front-end of a charging infrastructure assessment platform that processes and represents real-life charging data. Charging infrastructure planning and design methods described in the literature use geographic information system data, traffic flow data of non-EV vehicles, or geographical distributions of, for example, refueling stations for combustion engine vehicles. Only limited methods apply real-life charging data. Rolling out public charging infrastructure is a balancing act between stimulating the transition to zero-emission transport by enabling (candidate) EV drivers to charge, and limiting costly investments in public charging infrastructure. Five key performance indicators for charging infrastructure utilization are derived from literature, workshops, and discussions with practitioners. The paper describes the Data Warehouse architecture designed for processing large amounts of charging data, and the web-based assessment platform by which practitioners get access to relevant knowledge and information about the current performance of existing charging infrastructure represented by the key performance indicators developed. The platform allows stakeholders in the decision-making process of charging point installation to make informed decisions on where and how to expand the already existing charging infrastructure. The results are generalizable beyond the case study regions in the Netherlands and can serve the roll-out of charging infrastructure, both public and semi-public, all over the world.

Combining soft system methodology and pareto analysis in safety management performance assessment

Although reengineering is strategically advantageous fororganisations in order to keep functional and sustainable, safety must remain apriority and respective efforts need to be maintained. This paper suggeststhe combination of soft system methodology (SSM) and Pareto analysison the scope of safety management performance evaluation, and presents theresults of a survey, which was conducted in order to assess the effectiveness,efficacy and ethicality of the individual components of an organisation’s safetyprogram. The research employed quantitative and qualitative data and ensureda broad representation of functional managers and safety professionals, whocollectively hold the responsibility for planning, implementing and monitoringsafety practices. The results showed that SSM can support the assessment ofsafety management performance by revealing weaknesses of safety initiatives,and Pareto analysis can underwrite the prioritisation of the remedies required.The specific methodology might be adapted by any organisation that requires adeep evaluation of its safety management performance, seeks to uncover themechanisms that affect such performance, and, under limited resources, needsto focus on the most influential deficiencies.

Rapportage (deel)project performance assessment Fontys pabo's. Ervaringen in de pilots bij de Fontys pabo's Eindhoven, 's-Hertogenbosch, Tilburg en Limburg.

In september 2001 is het rapport Toetskader en prototypen gemeenschappelijke toetsvormen: performance assessments, portfolio en itembank uitgebracht door de ontwikkelgroep Assessment Pabo s. In het project Performance Assessment P-fase en K-fase Fontys-pabo s zijn pilots uitgevoerd. Verder is een prototype ontwikkeld voor informatie en communicatie rond de assessments in de elektronische leeromgeving. In het rapport staat hoe de pilots bij de verschillende pabo s zijn uitgevoerd. Vervolgens wordt ingegaan op de resultaten van de uitgevoerde onderzoeken. Aan het einde van elke paragraaf worden conclusies geformuleerd. Tot slot worden adviezen voor het vervolg gegeven.

A scoring rubric for performance assessment of information literacy in Dutch Higher Education

The main purpose of the research was the development and testing of an assessment tool for the grading of Dutch students' performance in information problem solving during their study tasks. Scholarly literature suggests that an analytical scoring rubric would be a good tool for this.Described in this article are the construction process of such a scoring rubric and the evaluation of the prototype based on the assessment of its usefulness in educational practice, the efficiency in use and the reliability of the rubric. To test this last point, the rubric was used by two professors when they graded the same set of student products. 'Interrater reliability' for the professors' gradings was estimated by calculating absolute agreement of the scores, adjacent agreement and decision consistency. An English version of the scoring rubric has been added to this journal article as an appendix. This rubric can be used in various discipline-based courses in Higher Education in which information problem solving is one of the learning activities. After evaluating the prototype it was concluded that the rubric is particularly useful to graders as it keeps them focussed on relevant aspects during the grading process. If the rubric is used for summative evaluation of credit bearing student work, it is strongly recommended to use the scoring scheme as a whole and to let the grading work be done by at least two different markers.
