The state-of-the-art of collaborative technologies for initial vocational education : a systematic literature review
2018

 
 
 Future workplaces require collaboration skills in which members of different work communities use technologies to solve complex problems. Vocational education and training (VET) programs need to meet the challenge to prepare students to be part of a competent workforce. Particularly initial vocational education is under pressure to develop learners’ collaboration skills and abilities. To date, however, no attempt has been made to perform a comprehensive review of the use of computer-supported collaborative learning (CSCL) technologies across different vocational education settings to account for contextual factors of VET. In this systematic review, 26 published studies …
Processing and effectiveness of formative feedback to increase comprehension and learning of conceptual knowledge in digital environments
2019
Los estudiantes de educación secundaria participan diariamente en tareas académicas diseñadas para desarrollar habilidades de lectura y facilitar la adquisición de conocimientos. Habitualmente, los docentes suelen pedir a sus estudiantes que lean textos expositivos y respondan preguntas sobre sus contenidos (e.g., Ness, 2011; Sánchez y García, 2015; Sánchez, García y Rosales, 2010), ya que estas tareas respaldan la comprensión y el aprendizaje de conceptos e ideas (e.g., Anmarkrud, McCrudden, Bråten y Strømsø, 2013; Cerdán, Gilabert y Vidal-Abarca, 2011; Lewis y Mensink, 2012; Roelle y Berthold, 2017). En estas situaciones, los estudiantes han de aplicar tanto procesos cognitivos de compres…
Finnish upper secondary level students' experiences and preferences of user-generated media content in the EFL classroom
2017
Kielten opiskelu on yhä multimodaalisempaa. Tutkimustieto tietyistä medioista ja välineistä luokkahuoneessa on kasvanut viimeisen vuosikymmenen aikana sekä kansainvälisesti, että Suomessa. Erityisesti opettajien näkemyksiä ja kokemuksia erilaisten internet materiaalien käytöstä osana opetusta on tutkittu, mutta tämän seurauksena oppilaiden näkökulma on jäänyt vähäiseksi. Tutkielman fokukseksi valikoitui käyttäjäkeskeiset mediat. Käyttäjäkeskeisillä medioilla tarkoitetaan internet materiaaleja, joiden sisältö on sivun käyttäjien tuottamaa ja jakamaa. Käyttäjäkeskeisten medioiden huomio keskittyy siis luovaan sisältöön ja sen tuottamiseen. Tästä hyviä esimerkkejä ovat muun muassa YouTube ja W…
Proclivity of sexual harassment and blame attribution in journalism: experiential narratives of ghanaian female journalists
2021
Though the proclivity of sexual-related harassments in African journalism is high, the rates of reporting of these incidences and empirical studies are low. Using a gendered approach, the study presents and exploratory inquiry into the lived experiences and impressions of Ghanaian female journalists about incidences of sexual harassments. The study examines how female journalists experience both newsroom harassments and on-assignment sexual harassments including the role they play in quid pro quo exchanges, which are relevant aspects of sexual harassments in the profession. The study also looks at blame attribution strategies female journalists adopt in assigning blame for sexual harassment…
Enseñanza de los conceptos de cantidad de sustancia y de mol basada en un modelo de aprendizaje como investigación orientada
2007
This study deals with the design and implementation of a research on the concepts of «amount of substance» and «mol». This work is grounded on a constructivistic conception of the learning of Sciences, more particularly on the model known as teaching-learning as oriented research. In accordance with this theoretical basis we have developed an empirical research framed within the teaching of Chemistry in High School. The developed designs have enabled us to assess the learning achieved by the students from a conceptual, procedural and attitudinal stance. According to our fi ndings we could say that the materials developed and the way we have worked with them have contributed to a more signif…
Errores conceptuales en el estudio del equilibrio químico : nuevas aportaciones relacionadas con la incorrecta aplicación del principio de Le Chateli…
2021
Resumen basado en el de la publicación Resumen en inglés La utilidad limitada del principio de Le Chatelier y su formulación vaga y ambigua pueden ser algunas de las fuentes de conceptos erróneos en el equilibrio químico. Para diagnosticar conceptos erróneos, se administró una prueba escrita a 170 estudiantes universitarios de primer año. Las respuestas revelaron que los errores surgieron en términos generales: a) la mala aplicación y la incomprensión del Principio de Le Chatelier; b) utilización de recordatorios de memorización y procedimientos algorítmicos; c) control incorrecto de las variables involucradas y uso limitado de la ley de equilibrio químico; d) falta de dominio de los princi…
Using Talking Books to Support Early Reading Development
2009
This chapter explores the question of how interactive multimedia talking books can promote young children’s literacy development. Whilst commercially available talking books can motivate young children to read, there is little evidence that they are linked to the development of skills known to promote reading itself. The ‘Bangers and Mash’ talking books (Chera, 2000), were designed to address this issue, and we review studies that evaluated their effectiveness as classroom resources that could promote reading-related skills and abilities. We then consider the various barriers to collaborative learning in Early Years classrooms, and describe how resources like talking books could address som…
Radiomics Analysis of Brain [18F]FDG PET/CT to Predict Alzheimer’s Disease in Patients with Amyloid PET Positivity: A Preliminary Report on the Appli…
2022
Background: Early in-vivo diagnosis of Alzheimer’s disease (AD) is crucial for accurate management of patients, in particular, to select subjects with mild cognitive impairment (MCI) that may evolve into AD, and to define other types of MCI non-AD patients. The application of artificial intelligence to functional brain [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography(CT) aiming to increase diagnostic accuracy in the diagnosis of AD is still undetermined. In this field, we propose a radiomics analysis on advanced imaging segmentation method Statistical Parametric Mapping (SPM)-based completed with a Machine-Learning (ML) application to predict the diagnosi…
Application of selected supervised classification methods to bank marketing campaign
2016
Supervised classification covers a number of data mining methods based on training data. These methods have been successfully applied to solve multi-criteria complex classification problems in many domains, including economical issues. In this paper we discuss features of some supervised classification methods based on decision trees and apply them to the direct marketing campaigns data of a Portuguese banking institution. We discuss and compare the following classification methods: decision trees, bagging, boosting, and random forests. A classification problem in our approach is defined in a scenario where a bank’s clients make decisions about the activation of their deposits. The obtained…
Improvements and applications of the elements of prototype-based clustering
2018
Clustering or cluster analysis is an essential part of data mining, machine learning, and pattern recognition. The most popularly applied clustering methods are partitioning-based or prototype-based methods. Prototype-based clustering methods usually have easy implementability and good scalability. These methods, such as K-means clustering, have been used for different applications in various fields. On the other hand, prototype-based clustering methods are typically sensitive to initialization, and the selection of the number of clusters for knowledge discovery purposes is not straightforward. In the era of big data, in high-velocity, ever-growing datasets, which can also be erroneous, outl…
