Nature area Rammegors, which has recently been transformed from a fresh inner-dyke nature area to a salt tidal area. Due to this transformation, salt water is infiltrating in a fresh waterlens. This salinisation process is investigated in more detail by two- and three dimensional models together with mearsurements in the area. Zeeland project FRESHEM has provided detailed isohaline maps of the area and Deltares is making transient isohaline maps based on measurements made by an ERT-cable which is situated in Rammegors. These data has been and will be used to investigate which factors; bathymetry, lithology, tides or regional groundwater flow, will have the largest impact on the salinization process in Rammegors. This investigation shows that discretization size has an influence on the speed and spatial distribution of salt plumes. Lithology has the largest influence on the salinization process, followed by bathymetry. Spring and neap tides do differ from the normal tides situation only when bathymetry is not taken into account.

Land subsidence by peat oxidation leads to enhanced salinization through boils in Dutch polders
Louw, Perry G.B. de; Bootsma, Huite ; Kooi, Henk ; Kramer, Mark ; Erkens, Gilles - \ 2018
In: 25th Salt Water Intrusion Meeting (SWIM 2018). - EDP Sciences (E3S Web of Conferences ) - 6 p.

Peat oxidation in deep Dutch polders leads - in addition to subsidence - to the development of new saline boils, enhancing the salinization of these polders. This on-going process is studied in detail in the Middelburg-Tempelpolder. The objective of the study was to get more in-depth knowledge about this process and to assess it for the present situation and for future landscapes (after 10, 50, 100 and 500 years).

In the European TOPSOIL project, countries around the North Sea are searching for solutions for climate related threats. They explore the possibilities of using the topsoil layer to solve current and future water challenges. The main objective is to improve the climate resilience of the water management of the topsoil and shallow aquifers in the North Sea region. TOPSOIL is supported by the Interreg VB North Sea Region program in line with priority 3 of the program: 'Sustainable North Sea Region, protecting against climate change and preserving the environment'. The Belgian part of this project, called FRESHEM for GO-FRESH Vlaanderen ('FREsh Salt groundwater distribution by Helicopter ElectroMagnetic survey for Geohydrological Opportunities FRESH water supply'), focuses on mapping the salinity distribution of groundwater using airborne electromagnetics and aims to look into a number of measures that could increase the availability of freshwater for agriculture in the polder area. Two pilot projects will evaluate the possibilities for freshwater storage and aims to specify what measures can be taken to achieve this. Together with the other water users and water managers, The Flanders Environment Agency wants to prepare a plan for the realization of one or more pilot projects that can improve the availability of freshwater.

Job demands - job resources - motivation - self-determination theory - teacher professional learning

Although teachers’ commitment to continuous professional learning is crucial for high quality education, research shows that this learning cannot be taken for granted. To better understand how teachers’ learning at work can be supported, this study investigates how effects of job demands (i.e. work pressure and emotional pressure) and job resources (i.e. task autonomy, transformational leadership, and collegial support) on teachers’ learning commitment (i.e. learning frequency and engagement) can be explained by basic psychological need satisfaction and autonomous motivation, as posited by self-determination theory. At two occasions, approximately one year apart, data was collected in a sample of 678 (T1) and 536 (T2) Dutch secondary school teachers. Structural equation models showed the consecutive positive longitudinal relationships between teachers’ experience of job resources, basic psychological need satisfaction, autonomous motivation, and commitment to professional learning. Job demands were not related to basic need satisfaction over and above the effects of job resources. Implications for how self-determination theory and the job demands resources model can mutually inform each other are discussed. In addition, implications for stimulating teachers’ professional learning in practice are provided.

Benin - Discharge loss - Flow modelling - Groundwater recharge - Ouémé - River leakage

Study area: The coastal sedimentary basin including the Zou and Ouémé rivers in Benin. Study focus: River discharge loss is known to occur on the Zou and Ouémé rivers in southern Benin since a couple of decades ago. The reason behind this discharge reduction remained so far unclear. In this study, we focus on creating a 3D-numerical model of the system and on evaluating the sensitivity of leakage between the rivers and aquifers to various parameters. New hydrological insights for the region: Results show that leakages along the Zou river and Ouémé stream are tiny (i.e., ∼3% of the discharge losses). This implies that the observed water loss from the Zou and Ouémé rivers is not likely caused by the leakage (infiltration) along these rivers into the subsurface. The streambed conductance is found to be among the factors that impact less the computed leakages in the study area. This study has ranked the different hydraulic and storage properties in their order of importance with respect to the computation of river leakages along the concerned rivers. The determined rank of importance of the hydraulic and storage properties can guide river leakage modelling exercises in similar regions elsewhere.

The relation between teachers’ interpersonal role identity and their self-efficacy, burnout and work engagement
Want, Anna C. Van Der; Brok, Perry Den; Beijaard, Douwe ; Brekelmans, Mieke ; Claessens, Luce C.A. ; Pennings, Helena J.M. - \ 2018

This study investigated the relation between teachers’ interpersonal role identity on the one hand and teachers’ self-efficacy, burnout and work engagement on the other. Data was collected using questionnaires and semi-structured and video-stimulated interviews. Results especially showed differences for self-efficacy between the teachers’ interpersonal role identities. The results indicate that teacher educators and coaches at schools can support (student) teachers (1) by helping them to discover and making them aware of their interpersonal identity standard and (2) by facilitating their growth towards a match between their interpersonal identity standard and their appraisal of classroom situations.
Investigating effects of using digital video in teacher training in Cambodia
Lok, L. ; Schellings, G. ; Brouwer, N. ; Brok, Perry den - \ 2018
Journal of Technology and Teacher Education 26 (2018)2. - ISSN 1059-7069 - p. 275 - 298.
While research has shown that video can be an effective tool in the professional learning of teachers in industrialized countries, it is unknown whether this is also true for other countries with distinctive cultural, political, and historical contexts, such as Cambodia. This paper presents results from a study which examined the effectiveness of using video to introduce student-centered teaching to teachers in Cambodia. The training consisted of collaboratively watching and discussing videos of teaching practices. A 2x2 design was used, varying group conditions (team versus pair) and relevance of the material (model video versus action video). The findings indicated that although it was not possible to determine if there had been changes in teacher behavior, using video had led to an increase in teachers’ perceived knowledge of student-centered teaching, especially for the team and the model video conditions.

in-service teachers - student teachers - systematic literature review - Teacher professional development

The aim of this review in the form of a realist synthesis is to understand what makes peer (student) teacher learning activities effective. Three types of peer learning were explored: collaborative, coaching, and assessment activities. Hypotheses were developed and tested against a set of 63 studies. These hypotheses indicated what mechanisms (i.e., characteristics of the activities) would influence the effectiveness of the activities and which contexts (i.e., factors) influenced this process. Findings showed that activities wherein participants gain subject matter and pedagogical content knowledge and apply this into practice made such learning effective. Peer learning is also reinforced by facilitators, reflection, and feedback, and influenced by personal and interpersonal factors. The main contribution of this realist synthesis is the practical implications for developers of peer learning activities, for school leaders and teacher educators, and for (student) teachers.

Do outreach activities in secondary STEM education motivate students and improve their attitudes towards STEM?

motivation - Outreach - secondary education - STEM - subject-related attitudes

The present study investigated outreach activities, developed by STEM-based companies or universities in co-creation with secondary education with the aim to inform students about and motivate them for a career in STEM by connecting the work-context with school-science. Although many of such activities are being offered, little is known about their effects. We investigated students’ perceptions with the outreach learning environment, perceived need-fulfilment, self-reported motivation and attitudes towards STEM. Data were gathered from 729 high-school students engaged in 12 activities in the USA and the Netherlands. The students completed a questionnaire, which contained questions about four elements of our theoretical frame based on the Self-Determination-Theory (SDT). Perceived needs-fulfilment and motivation were measured using the basic-psychological-needs-scale and the self-regulation-questionnaire. Attitudes were measured using the test-of-science-related-attitudes. Learning environment perceptions were measured in a previous study using subscales of what-is-happing-in-this-classroom (WIHIC), constructivist-learning-environments-scale (CLES) and classroom-environment-scale (CES) and typified by activity characteristics. Multilevel analyses of variance were conducted for the two motivation scales (controlled and autonomous-motivation) and the two attitude scales (social-implication and career-interest). Activity characteristics explained almost all variance in these variables between activities. Specific characteristics of outreach activities that statistically significantly related to autonomous motivation and positive general attitudes towards STEM were: workshop-format, understanding science, an out-of-school component. The attitude towards a possible STEM-career was positively associated with autonomous-motivation and negatively associated with controlled-motivation. Thus, outreach learning environments indeed created opportunities to increase students’ motivation in STEM and attitude towards STEM, but the impact varied according to particular characteristics of the activities.

Praktijkgericht onderzoek

Het belang van praktijkgericht onderzoek is zowel voor het onderwijsveld, als voor de lerarenopleidingen sinds de eeuwwisseling sterk toegenomen. Over de term praktijkgericht onderzoek en de positionering ervan, bestaat echter veel onduidelijkheid. In dit hoofdstuk maken we onderscheid tussen praktijkgericht onderzoek, onderzoek gericht op het verbeteren van de brede onderwijspraktijk en praktijkonderzoek, (docent-)onderzoek gericht op de verbetering van het onderwijs op de eigen school of opleiding. Bij praktijkgericht onderzoek onderscheiden we vier stappen: vraagarticulatie, kennisproductie, kennistransfer en kennisgebruik. Bij praktijkonderzoek belichten we drie functies van onderzoek in de school, de feedbackfunctie, de dialoogfunctie en de ontwerpfunctie. Voor beide typen onderzoek benoemen we diverse condities die gerealiseerd moeten zijn, voordat er sprake kan zijn van daadwerkelijke impact in de onderwijspraktijk. Een van de voorwaarden is een onderzoekende houding van leraren. Voor de ontwikkeling van een onderzoekende houding van aankomende leraren is de voorbeeldrol van opleidingsdocenten cruciaal.

The research field regarding the relationship between the psychosocial learning environment (PSLE) and the physical learning environment (PLE) requires a commonly accepted theoretical framework, enabling comparison of research results and construction of a shared body of knowledge. Based on selected and reviewed literature, this study explores existing conceptualisations, distilling the main aspects as identified by earlier research, and processes these findings in a preliminary conceptual framework. This framework structures the PSLE into the dimensions: personal development; relationships; and system maintenance and change, and the PLE into the dimensions naturalness; individualisation; and stimulation. For each of these dimensions, the framework distinguishes the intended, implemented, and attained representation. Compared to the conceptualisations used in the reviewed literature, this preliminary conceptual framework is more comprehensive, with a balanced representation of both the PSLE and PLE. Further development and empirical testing will be necessary to demonstrate the validity, usability and reliability of the framework.
