Towards the realization of a basic professional profile model for Science, Technology and Mathematics (STEM) teachers
2017
[EN] In this work it is both discussed and provided a framework of speci c competences that may serve asa guide for setting up an ongoing process in the professional development of Science, Technology andMathematics (STEM) teachers. The fundamentals of the TPACK model serve to base the theoreticalbackground of this scheme, to which we have incorporated an additional feature which means to considerthe linguistic (L) dimension, thus transforming it into the TPACLK model. The di erent detailed profes-sional STEM capacities have been classi ed into six main sections. The two rst points discussed establishthe STEM disciplinary and didactic capacities; the third section corresponds to the role of…
Spatial Perspective on Everyday Transitions Within a Toddler Group Care Setting
2017
This chapter builds on spatial approaches to study everyday life, and in particular to consider Henri Lefebvre’s (1901–1991) theory on the social production of space. Lefebvre’s ideas on the social production of space are based on a dynamic “spatial triad” of conceived (representations of space), perceived (socio-spatial practices), and lived space (representational space). The aim of this chapter is to discuss, by building on Lefebvre’s approach, the spatial dynamics involved within the small-scale (horizontal) transitions for children in toddler group care. The discussion is based on a study where one Finnish day care group for 1- to 3-year-olds was investigated by applying a spatial, rel…
Teacher Guidance in Mathematical Problem-Solving Lessons: Insights from Two Professional Development Programs
2019
When implementing a problem-solving lesson, the teacher needs to provide students appropriate guidance during problem solving. This demanding task requires understanding students’ work in progress and giving them necessary help without constraining their thinking. In this article, we share insights from two professional development programs on how teachers guided students’ problem solving and how they reflected on these instances. One of the programs included Finnish pre-service teachers, while the other program included US in-service teachers. We analyzed video-recorded problem-solving lessons from 16 Finnish and 2 US teachers in grades 6–9. We found two themes about teacher guidance of st…
Quantification and classification in education: What is at stake?
2021
Histories of statistics and quantification have demonstrated that systems of statistical knowledge participate in the construction of the objects that are measured. However, the pace, purpose, and scope of quantification in state bureaucracy have expanded greatly over the past decades, fuelled by (neoliberal) societal trends that have given the social phenomenon of quantification a central place in political discussions and in the public sphere. This is particularly the case in the field of education. In this article, we ask what is at stake in state bureaucracy, professional practice, and individual pupils as quantification increasingly permeates the education field. We call for a theoret…
Revista complutense de educación
2020
espanolEn un barrio de la ciudad de Valencia, dos grupos de mujeres, uno de cultura gitana y otro de no gitana, junto con el profesorado y las familias de la escuela publica, inician un recorrido de conocimiento y transformacion mutuos. En el citado barrio y en el centro escolar se habian detectado problemas de convivencia entre los grupos de diferentes culturas. El proyecto se basa en una pedagogia comprometida con la investigacion-accion participativa y transformativa de la comunidad que hunde sus raices en las narrativas, en la reflexion y en la practica transformadora. En el diseno y seguimiento del proyecto, aplicamos una metodologia etnografica para analizar el conjunto de la realidad…
A Clustering approach for profiling LoRaWAN IoT devices
2019
Internet of Things (IoT) devices are starting to play a predominant role in our everyday life. Application systems like Amazon Echo and Google Home allow IoT devices to answer human requests, or trigger some alarms and perform suitable actions. In this scenario, any data information, related device and human interaction are stored in databases and can be used for future analysis and improve the system functionality. Also, IoT information related to the network level (wireless or wired) may be stored in databases and can be processed to improve the technology operation and to detect network anomalies. Acquired data can be also used for profiling operation, in order to group devices according…
Reviving the lost spaces under urban highways and bridges: an empirical study
2019
Purpose The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design. Design/methodology/approach This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by conten…
Mitigation and boosting as face-protection functions
2020
Abstract Mitigation is undeniably and necessarily linked with the social aspect of communication. No speaker mitigates an utterance without a goal in mind, which makes mitigation a means to an end and not an end in itself. Even though the various definitions of mitigation do not assign the same aims to this phenomenon, the social impact it has on the participants in the communication is generally agreed upon throughout the literature (Fraser, 1980; Meyer-Hermann, 1988; Bazzanella et al., 1991; Briz, 1998, 2003; Caffi, 1999; Thaler, 2012; Briz and Albelda, 2013; Schneider, 2013; Albelda et al., 2014; Albelda, 2016, 2018). In this paper, the mitigating and boosting strategies in relationship …
Professional Embodiment: Walking, Re-engagement of Desk Interactions, and Provision of Instruction during Classroom Rounds
2018
Abstract Unlike continuous whole-class (plenary) interaction, independent task work involves incipient teacher–student talk, as the teacher typically ‘makes rounds’ to engage in brief desk interactions with students. This article draws on multimodal conversation analysis to investigate how teacher movement during tasks offers resources for re-engaging in desk interactions and offering task-related guidance. The focus is on teachers’ walking trajectories and ways of positioning the body, and students’ orientation to them, in (i) (pre-)opening moments of a desk interaction, and (ii) during a subsequent instructional turn that guides students with the ongoing task. The analysis shows how the p…
A New Paradigm in Interactive Evolutionary Multiobjective Optimization
2020
Over the years, scalarization functions have been used to solve multiobjective optimization problems by converting them to one or more single objective optimization problem(s). This study proposes a novel idea of solving multiobjective optimization problems in an interactive manner by using multiple scalarization functions to map vectors in the objective space to a new, so-called preference incorporated space (PIS). In this way, the original problem is converted into a new multiobjective optimization problem with typically fewer objectives in the PIS. This mapping enables a modular incorporation of decision maker’s preferences to convert any evolutionary algorithm to an interactive one, whe…
