Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies

2023

Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…

Refamilisation in the broadband society – the effects of ICTs on family solidarity in Finland

2021

In this article we explore the effects that new information and communication technologies (ICTs) have on family relations in Finland. The idea of ‘new connectivities’ works as a starting point for the study directing attention to ICT-mediated forms of being together with distant family members. The research data consists of 22 student reports encompassing a total of 133 informants from extended Finnish families. Extended group interview (EGI) technique was developed and used for data collection in order to grasp the underlying social practices and values behind the use of ICTs in extended families. The results show that new ICTs, especially mobile social media, enhance family solidarity am…

Exploring problems associated with the sharing economy

2018

As the sharing economy has become more popular, its problems are discussed increasingly. However, these discussions are often confusing because there are multiple definitions for the sharing economy, and the discourse does not usually specify which definition it is based on. Therefore, the actors may be wrongfully accused of problems that do not concern them, only because they are perceived as belonging to the sharing economy. We aim to clarify this discussion by creating a framework that maps specific problem discourses to specific actors and stakeholder groups. We create a framework based on a review of the academic literature in which the sharing economy is delineated into smaller market…

Exploring sequential interplay between challenges and regulatory processes in collaborative learning with process mining

2023

This study explored the sequential interplay between challenges and regulatory processes in high- and low-performing collaborative groups. 66 students from a Finnish higher education institution participated in a collaborative task in groups of three. Approximately 34 h of video data were coded. The sequential analysis revealed that both groups had higher sequential transitions between cognitive regulation and emotional/motivational regulation, rather than cognitive challenges. The high-performing groups demonstrated a stronger sequential link between emotional/motivational regulation and cognitive regulation than the low-performing groups did when faced with cognitive challenges. The study…

“You really brought all your feelings out” : Scaffolding students to identify the socio-emotional and socio-cognitive challenges in collaborative lea…

2021

The aim of this study is to explore how students experience and describe socio-cognitive and socio-emotional challenges in collaborative learning. The participants (N = 20) were teacher education students whose collaborative learning was supported with a designed regulation macro script during a six-week mathematics course. The purpose of the script was to provide structured phases during the collaborative learning tasks for the group members to plan, monitor, and evaluate their workings. The video data of groups' face-to-face work was collected and analysed by focusing on the different types of challenges the groups experienced and the types of challenges they described during the scripted…

Collaborative Leadership in the Institutions of Higher Education : A Literature Review

2022

This study aims to review the literature concerning collaborative leadership in the context of institutions of higher education. The study covers empirical research from 2000 to 2021, providing insights into how collaborative leadership in this context is understood. Material for the study consists of 20 articles, which are analysed using qualitative content analysis. The analysis identifies three major categories highlighted in the literature as significant characteristics of collaborative leadership: namely, the participation of diverse people accelerates collaboration, learning transpires through collaboration, and empowerment leads to momentous change. This paper concludes with suggesti…

Social, health care and rehabilitation educators' competence in professional education—Empirical testing of a model

2021

The social and health care educator's role in educating future professionals need to be stronger emphasised and deserves international recognition. The purpose of this study was to develop and test an empirical model of social and health care educators' competence in higher and professional education. The presented research employed a cross-sectional study design. Data were collected using HeSoEduCo-instrument from 28 educational institutions in Finland. The model was empirically tested with confirmatory factor analysis through Structural Equation Modelling that applied the Full Imputation Maximum Likelihood estimator. A total of 422 social and health care educators participated in the stud…

MODELING PUBLIC POLICIES ANALYSIS OF LOGISTICS COLLABORATION IN THE PERFORMANCE OF THE AGRICULTURAL SECTOR OF THE POTATO IN COLOMBIA.

2020

The agricultural sector is considered fundamental for the supply of food needs of humanity, given the population growth. According to the Food and Agriculture Organization (FAO), the world population is estimated to be 9 billion people by the year 2050 and where the conditions of climate change can decrease crop yield up to 25%. This triggers greater vulnerability to the neediest population, being the rural sector the one hosting the poorest people. The rural area of Colombia represents 94% of extend the national territory, where 24% of the population lives a scenario of multiple problems that affect the country, such as the armed conflict of more than five decades, the presence of illicit …

Co-reductive fabrication of carbon nanodots with high quantum yield for bioimaging of bacteria

2018

A simple and straightforward synthetic approach for carbon nanodots (C-dots) is proposed. The strategy is based on a one-step hydrothermal chemical reduction with thiourea and urea, leading to high quantum yield C-dots. The obtained C-dots are well-dispersed with a uniform size and a graphite-like structure. A synergistic reduction mechanism was investigated using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The findings show that using both thiourea and urea during the one-pot synthesis enhances the luminescence of the generated C-dots. Moreover, the prepared C-dots have a high distribution of functional groups on their surface. In this work, C-dots proved …
