Relations between representational consistency, conceptual understanding of the force concept, and scientific reasoning

2012

Previous physics education research has raised the question of “hidden variables” behind students’ success in learning certain concepts. In the context of the force concept, it has been suggested that students’ reasoning ability is one such variable. Strong positive correlations between students’ preinstruction scores for reasoning ability (measured by Lawson’s Classroom Test of Scientific Reasoning) and their learning of forces [measured by the Force Concept Inventory (FCI)] have been reported in high school and university introductory courses. However, there is no published research concerning the relation between students’ ability to interpret multiple representations consistently (i.e.,…

A CO2-gas precursor to the March 2015 Villarrica volcano eruption

2017

We present here the first volcanic gas compositional time-series taken prior to a paroxysmal eruption of Villarrica volcano (Chile). Our gas plume observations were obtained using a fully autonomous Multi-component Gas Analyser System (Multi-GAS) in the 3 month-long phase of escalating volcanic activity that culminated into the 3 March 2015 paroxysm, the largest since 1985. Our results demonstrate a temporal evolution of volcanic plume composition, from low CO$_2$/SO$_2$ ratios (0.65-2.7) during November 2014-January 2015 to CO$_2$/SO$_2$ ratios up to ≈ 9 then after. The H$_2$O/CO$_2$ ratio simultaneously declined to <38 in the same temporal interval. We use results of volatile saturatio…

Sulfur Degassing From Steam-Heated Crater Lakes: El Chichón (Chiapas, Mexico) and Víti (Iceland)

2018

The composition of the gases released by El Chichón (Chiapas, Mexico) and Víti (Askja volcano, Iceland) volcanic lakes is examined by Multi-GAS for the first time. Our results demonstrate that H2S and SO2 are degassed by these pH 2–3 lakes. We find higher CO2/H2S and H2/H2S ratios in the lakes' emissions (31–5,685 and 0.6–35, respectively) than in the fumarolic gases feeding the lakes (13–33 and 0.08–0.5, respectively), evidencing that only a fraction (0.2–5.4% at El Chichón) of the H2S(g) contributed by the subaquatic fumaroles ultimately reaches the atmosphere. At El Chichón, we estimate a H2S output from the crater lake of 0.02–0.06 t/day. Curiously, SO2 is also detected at trace levels …

Developing response-ability in human-wasp encounters

2023

Learning to live with unloved others is crucial in the ecological crisis. Unloved wasps are feared and disliked for their sting. Understanding of their ecological importance is increasing, however. Human-wasp encounters are changing with environmental changes, and strategies for multispecies cohabitation are needed. This multispecies study highlights features of wasp biology affecting human-wasp encounters and analyzes how conflicted human-wasp relations could be mitigated. The geographical focus is Finland, in the Northern boreal region. Biological analysis specified spatiotemporal aspects affecting human-wasp encounters: human and wasp habitats and preferences overlap ubiquitously. From a…

Kohtaamisia : yhteistoiminnan rakentuminen pariterapian reflektiivisten prosessien muutoskohdissa

2017

Pro gradu -tutkielmassa tarkastelimme vuorovaikutustutkimuksen keinoin, miten yhteistoiminta rakentui hetki hetkeltä pariterapian reflektiivisten prosessien muutoskohdissa. Käyttämämme aineisto koostui Jyväskylän yliopiston Relationaalinen mieli -tutkimushankkeen yhteydessä kerätyistä videoidusta pariterapiaistunnoista. Kävimme läpi 62 videoitua pariterapiaistuntoa ja valikoimme niistä yhdeksän reflektiivisten prosessien aikaista muutoskohtaa. Muutoskohtina käsittelimme sellaisia reflektiivisen prosessin aikana esiintyneitä vuorovaikutusepisodeja, joihin sisältyi näkyviä vuorovaikutusresponsseja kummaltakin asiakaspariskunnan osapuolelta. Kehitimme monitoimijaisten vuorovaikutusepisodien li…

Perceived status and value

2017

This article examines how students in a multidisciplinary project-based learning course involving real customers perceive their interactions with their customers. The authors conducted a qualitative study and analysed students’ learning reports by means of a thematic network analysis. The analysis shows how students perceive their status in relation to their customers and how their perceptions of their work affect how they see the value of the projects. The authors consider their empirical findings in the context of the existing literature on university–industry collaboration and thereby summarize different scenarios of the contrasting working practices and priorities in academia and indus…

Kielikäsitykset vanhustyössä - asukkaiden, hoitajien ja esimiesten käsityksiä hyvästä vuorovaikutuksesta ja kielenkäytöstä

2018

In this article, we apply critical discourse analysis and ethnography to examine conceptionsand experiences of inclusive interaction and language use in the context of eldercare in aretirement home. Our data consist of interviews with residents, nurses and managers intwo bilingual eldercare units, as well as ethnographic observations of communication andlanguage use in these units. Our analysis focuses especially on language ideologies andmetalinguistic aspects of inclusive language in the context of eldercare. On the basis of ouranalysis, we suggest that four elements are particularly central to elderly-centric language: 1)the quality, quantity and tone of interaction; 2) the practices of …

Associations Among Teacher–Child Interactions, Teacher Curriculum Emphases, and Reading Skills in Grade 1

2017

Research Findings: The purpose of the present study was to examine the extent to which the quality of teacher–child interactions and teachers’ self-reported curriculum emphases are related to children’s reading skill development during their 1st school year. To accomplish this, we assessed the reading skills of 1,029 Finnish children (M age = 85.77 months) twice during Grade 1, and the children’s teachers (n = 91) completed questionnaires concerning their literacy-related curriculum emphases. In addition, teacher–child interactions in terms of emotional support, classroom organization, and instructional support were observed in 29 classrooms. The results of multilevel modeling showed that a…

Eye gaze as a resource in handling trouble around mobile devices in classroom interaction

2022

This paper offers an insight into how interaction is multimodally built during taskaccomplishment around mobile devices in classroom interaction. More specifically, it investigates eye gaze as a resource in recruiting help and pursuing response from peers during interactional or task-related trouble sequences. The data come from video-recorded lessons at Finnish comprehensive schools where mobile devices are used for learning tasks. Drawing on multimodal conversation analysis, the article demonstrates that gaze is employed by pupils as one of the first resources to display and address trouble. Although tasks often require gaze to be directed at devices, it can be flexibly reoriented to peer…
