Material scaffolding : Supporting the comprehension of migrant cleaners at work
2016
Linguistic diversity is growing in labour markets throughout Europe, including Finland, where cleaning is the most common job for immigrants. This paper explores material scaffolding provided for second language users in tasks involved in cleaning work. The notion of ‘scaffolding’ refers to temporary and adaptive support, and here the emphasis is especially on ‘material scaffolding’, that is, material artefacts and body movements employed in mentoring. The theoretical framework of the study is van Lier’s (2004) ecological perspective on language learning, and a discourse-ethnographic perspective of nexus analysis (Scollon and Scollon 2004) is adopted to analyse the ethnographic data collect…
No association of alcohol dependence with HOMER 1 and 2 genetic variants.
2010
Several lines of evidence indicate that alterations of the central cortico-accumbens glutamate pathway are involved in the development and maintenance of alcohol- and substance-use disorders. The HOMER protein family is encoded by 3 genes HOMER (1–3) which are components of the excitatory postsynaptic density complex and function to modulate synaptic activity by the regulation of glutamate signaling. HOMER 1 and 2 have been reported to contribute to chronic alcohol-induced long-term neurochemical changes in the endogenous reward system. Data from animal models suggest a potential role of the Homer protein family in the development of alcohol and substance use. The aim of this study is to as…
A53T-Alpha-Synuclein Overexpression Impairs Dopamine Signaling and Striatal Synaptic Plasticity in Old Mice
2010
BACKGROUND: Parkinson's disease (PD), the second most frequent neurodegenerative disorder at old age, can be caused by elevated expression or the A53T missense mutation of the presynaptic protein alpha-synuclein (SNCA). PD is characterized pathologically by the preferential vulnerability of the dopaminergic nigrostriatal projection neurons. METHODOLOGY/PRINCIPAL FINDINGS: Here, we used two mouse lines overexpressing human A53T-SNCA and studied striatal dysfunction in the absence of neurodegeneration to understand early disease mechanisms. To characterize the progression, we employed young adult as well as old mice. Analysis of striatal neurotransmitter content demonstrated that dopamine (DA…
Teachers' instructional scaffolding in an innovative information and communication technology-based history learning environment
2002
Abstract The nature of the role assumed by the teacher is crucial in the promotion of successful learning and collaboration in Information and Communication Technologybased (ICT-based) environments. The aim of this study was to examine how teachers with different conceptions of their teacher roles use different types of instructional scaffolding while working in an innovative learning environment. Our further aim was finding out how instructional scaffolding is related to learning activities of different kinds. The study was carried out at two secondary schools with a shared network-based learning environment. The results showed that teachers with different conceptions of the teacher's role…
Mācību modelis WebQuest augstāko domāšanas prasmju pilnveides atbalstam 11. klases biznesa angļu valodas stundās
2017
Skolas vadība motivēja Diplomdarba autoru mācību laikā izmantot modernās tehnoloģijas, bet darba autoram bija grūtības atrast jēgpilnu veidu kā tās iekļaut ikdienas mācību stundās. Tajā pat laikā, tika novērots, ka skolēniem ir grūtības pielietot augstākās domāšanas prasmes stundās. Lai risinātu augstāk minētās problēmas tika nolemts pielietot mācību modeli WebQuest augstāko domāšanas prasmju pilnveides atbalstam. Pētījuma metode bija gadījuma pētījums Babītes vidusskolā no 2016. gada septembra līdz 2016. gada decembrim un tajā piedalījās trīspadsmit 11. klases skolēni. Pētījuma laikā tika analizēts biznesa angļu valodas standarts, izstrādāta anketa skolēniem, kuru viņi aizpildīja, izveidot…
What can the concept of affective scaffolding do for us?
2020
The concept of affective scaffolding designates the various ways in which we manipulate the environment to influence our affective lives. In this article, I present a constructive critique of recent discussion on affective scaffolding. In Part 1, I summarize how the theories of situated mind and niche construction contribute to a multidimensional notion of scaffolding. In Part 2, I focus specifically on affective scaffolding and argue that current ambiguity over its distinctive criteria causes uncertainty as to how the concept can and should be used. In Part 3, I identify and examine two possible responses to the suggested state of conceptual ambiguity. The first, restrictive option is to k…
Writting practice for developp mind and language
2016
This thesis wanted to put on the opposite between established culture, transmitted by School, and private culture, the VAE candidates’ concerned by this research, as well as the author’s. This putting on the opposite is fed by a purpose: to show to what extent the individual and collective work of writing on practical, allows to articulate first the peculiarity of the subjects, the trajectories, the experiences, the situations and the activities, with the generalization of the institutional speech linked with the standardized procedures of the device VAE ? In a second time does this work of writing allows to build knowledges from the experience, object and source of development, and to make…
Suomen kielen oppimisen mahdollisuudet ja työyhteisön tuki puhdistuspalvelualalla: afrikkalaisten maahanmuuttajien käsityksiä ja kokemuksia
2013
This article presents a triple case study of African immigrants’ beliefs about Finnish language learning and support of the work community in the cleaning industry. Cleaning does not require a high language proficiency and it is therefore a typical first job for immigrants, a so-called entrance job. The theoretical framework of the study combines dialogical and sociocultural perspectives on language learning. Learners’ beliefs about work-related affordances and scaffolding are analysed using a dialogical analysis of beliefs. The interviewees’ shared belief is that in spite of their simple duties, cleaning work does provide affordances for learning, e.g. in the form of work-related announcem…
Scaffolding patterns of dialogic exchange in toddler classrooms
2021
The present study investigates how often episodes of dialogic exchange can be identified in educator–toddler interactions during play and emerging academic activities, what kind of scaffolding strategies educators use during the episodes of dialogic exchange and, ultimately, what kind of scaffolding patterns of dialogic exchange can be identified based on educators' use of scaffolding strategies. Educator–child interactions were video-recorded in seven European countries, in two toddler classrooms in each country. The video recordings of emerging academic and play activities were transcribed and analysed, combining the principles of theory and a data-driven content analysis. First, 69 episo…
The potential of temporal analysis: Combining log data and lag sequential analysis to investigate temporal differences between scaffolded and non-sca…
2020
This paper contributes to the ongoing discussion about analysing the temporal aspects of learning processes in the educational technology research field. Our main aim was to advance methods for analysing temporal aspects of technology-enhanced learning (TEL) processes by introducing the temporal lag sequential analysis (TLSA) technique and by combining TLSA with temporal log data analysis (TLDA). Our secondary aim was to illustrate the potential of these two analysis techniques to reveal the differences between the face-to-face technology-enhanced collaborative inquiry-based learning (CIBL) processes of three different conditions (non-scaffolded, writing scaffolded and script scaffolded gro…
