Providing high-quality feedback is essential for improving preservice teacher performance. Rather than post-lesson feedback, immediate performance feedback while teaching is considered effective. This article reports on developing and piloting a standardised tool for synchronous feedback. Eight teacher educators from a Dutch higher education institution were trained to use the tool (based on accepted models of teacher roles, observation criteria and feedback levels) with pre-recorded lessons. Interobserver reliability was good for teacher roles and sufficient for feedback levels. Positive evaluations of the tool and educators’ interest in its application, warrant further research into scalability and effectiveness of synchronous feedback delivery.
Research topic/aim The professional development of teacher educators (T Eds) is increasingly being recognised as a topic of paramount importance, partly caused by the attention for the lifelong learning of those responsible for teaching student teachers. In this presentation we focus on the professional development T Eds with regard to their role as second order practitioner (Murray and Male, 2005). Many T Eds identify themselves as a teacher in higher education and they lack attention for their specific role of being a teacher of teachers. In the project we investigated the possibilities of encouraging T Eds to focus on this role, by altering the procedure in which T Eds and their team-manager set development agreements. Theoretical and methodology framework Teacher Educators have specific roles and tasks (Lunenberg et al, 2012) and they need special skills to fulfil these roles. In the Netherlands, the Dutch Association of Teacher Educators has developed a professional standard, in which the skills for an average experienced teacher educator are described. In our project the professional standard served as a tool in the development agreement procedure for T Eds. In total 16 T Eds from 5 teams participated. In their preparation for the conversation with their team manager, T Eds studied this professional standard and used this to write down their strengths and development possibilities. After that, they entered the conversation with their team manager and came to development agreements. To study the effect of this new procedure, T Eds (two group interviews) and team managers were interviewed (one group interview) about their opinion on the preparation phase and the conversation itself. Results and conclusions Findings appear threefold. First, T Eds appreciate the use of the professional standard in the preparation. It helps them to focus on their role as teacher of teachers. Second, both team managers and T Eds mention that they now have 'words' to talk about the profession. Third, Teds and team managers both hold the opinion that the conversation itself is more thorough than it used to be before. Relevance to European educational research Our findings contribute to the body of knowledge around professional development activities for teacher educators, especially with regards to their role as second order practitioner or 'teacher of teachers' .
An essential condition to use mathematics to solve problems is the ability to recognize, imagine and represent relations between quantities. In particular, covariational reasoning has been shown to be very challenging for students at all levels. The aim of the project Interactive Virtual Math (IVM) is to develop a visualization tool that supports students’ learning of covariation graphs. In this paper we present the initial development of the tool and we discuss its main features based on the results of one preliminary study and one exploratory study. The results suggest that the tool has potential to help students to engage in covariational reasoning by affording construction and explanation of different representations and comparison, relation and generalization of these ones. The results also point to the importance of developing tools that elicit and build upon students' self-productions
Due to societal developments, like the introduction of the ‘civil society’, policy stimulating longer living at home and the separation of housing and care, the housing situation of older citizens is a relevant and pressing issue for housing-, governance- and care organizations. The current situation of living with care already benefits from technological advancement. The wide application of technology especially in care homes brings the emergence of a new source of information that becomes invaluable in order to understand how the smart urban environment affects the health of older people. The goal of this proposal is to develop an approach for designing smart neighborhoods, in order to assist and engage older adults living there. This approach will be applied to a neighborhood in Aalst-Waalre which will be developed into a living lab. The research will involve: (1) Insight into social-spatial factors underlying a smart neighborhood; (2) Identifying governance and organizational context; (3) Identifying needs and preferences of the (future) inhabitant; (4) Matching needs & preferences to potential socio-techno-spatial solutions. A mixed methods approach fusing quantitative and qualitative methods towards understanding the impacts of smart environment will be investigated. After 12 months, employing several concepts of urban computing, such as pattern recognition and predictive modelling , using the focus groups from the different organizations as well as primary end-users, and exploring how physiological data can be embedded in data-driven strategies for the enhancement of active ageing in this neighborhood will result in design solutions and strategies for a more care-friendly neighborhood.
Electrohydrodynamic Atomization (EHDA), also known as Electrospray (ES), is a technology which uses strong electric fields to manipulate liquid atomization. Among many other areas, electrospray is currently used as an important tool for biomedical applications (droplet encapsulation), water technology (thermal desalination and metal recovery) and material sciences (nanofibers and nano spheres fabrication, metal recovery, selective membranes and batteries). A complete review about the particularities of this technology and its applications was recently published in a special edition of the Journal of Aerosol Sciences [1]. Even though EHDA is already applied in many different industrial processes, there are not many controlling tools commercially available which can be used to remotely operate the system as well as identify some spray characteristics, e.g. droplet size, operational mode, droplet production ratio. The AECTion project proposes the development of an innovative controlling system based on the electrospray current, signal processing & control and artificial intelligence to build a non-visual tool to control and characterize EHDA processes.
In veel Afrikaanse landen zien we een inperking van de maatschappelijke ruimte (‘civic space’). Deze ruimte is cruciaal om in democratische staten transparantie, vrijheid van meningsuiting en verantwoording van bestuur te realiseren. In een steeds sterke digitaliserende maatschappij wordt toegang tot digitale middelen een mensenrecht. Daar waar regeringen proberen hun burgers en organisaties dat recht tot digitale informatievoorziening en –uitwisselingen te ontnemen komen de Sustainable Development Goals in het gedrang. Doel African Digital Rights Network (ADRN) wil inzicht verkrijgen in de stakeholders ne technologieën die betrokken zijn net het openen of onderdrukken van de online maatschappelijke ruimte (‘civic space’). Het netwerk beoogt bij te dragen aam empowerment van burgers om hun digitale mensenrechten uit te oefenen. Resultaten ADRN heeft een vergelijkende studie van 10 Afrikaanse landen uitgevoerd naar het gebruik van digitale technologieën voor het openen of onderdrukken van de online maatschappelijke ruimte (‘civic space’). Het project heeft onder andere geleidt tot de volgende publicatie: Mapping the Supply of Surveillance Technologies to Africa: Case Studies from Nigeria, Ghana, Morocco, Malawi, and Zambia Looptijd 01 mei 2020 - 20 april 2021 Aanpak ADRN organiseert een netwerk van onderzoekers, analisten, digitale rechtenorganisaties en activisten om de dynamiek van het openen en onderdrukken van de digitale maatschappelijke ruimte in kaart te brengen. Het netwerk bouwt op een interdisciplinaire onderzoeksaanpak o.l.v. het Institute for Development Studies, een vooraanstaand onderzoeksinstituut. Relevantie van het project Het onderzoek leidt tot aanbevelingen voor o.a. beleidsmakers en maatschappelijke organisaties ter bevordering van de digitale maatschappelijke ruimte. Daarnaast worden digitale tools en trainingsmateriaal gefaciliteerd voor het monitoren van ontwikkelingen en dreigingen van de digitale maatschappelijke ruimte.
