Perceived Support in E-Collaborative Learning: An Exploratory Study Which Make Use of Synchronous and Asynchronous Online-Teaching Approaches

2012

This study compares four different learning environments for e-collaborative learning in two European countries related to the dimension of student's mutual support. The theoretical baseline is Vygotsky's zone of proximal development (ZOPD) and the socio-genetic approach of Piaget. The analyzed data are based on questionnaires collected over the time period of an entire semester including four different courses at the master's level. These courses applied different e-collaborative approaches including a variety of tools for supporting communication. It is assumed that these courses including communication tools e.g. virtual face-to-face meetings enhance the chances for better communication,…

From Online Role-Play to Written Argumentation

2010

This chapter reports on a teaching experiment conducted during a blended learning course in social work in a Finnish university of applied sciences (polytechnic). The aim was to investigate how students’ multidimensional understanding of social problems could be fostered. As argumentative methods, the study used writing tasks, online role-play, and drama work. The data consisted of essays written by 65 students (experimental group 29; controls 36) in each of three phases, plus online discussions. The essays were based on 1) the students’ personal experiences, 2) general facts, and 3) a fictional case taken from the online role-play. Varying the focus of the writing task affected students’ s…

Blended Learning als Spielfeld für Learning Analytics und Educational Data Mining

2020

Der Einsatz digitaler Lernformate im Blended Learning bietet demnach Chancen in mindestens zwei Bereichen. Zum einen konnen digitale Lernformate direkt die Lernprozesse von Studierenden gunstig beeinflussen, ihre Leistungen verbessern und zudem positive Effekte auf vielen weiteren Ebenen wie der Motivation oder des Selbstkonzeptes bewirken. Zum anderen generieren digitale Lernformate eine Fulle von Daten in vielfaltiger Gestalt. Studierende erzeugen bei der Arbeit mit digitalen Werkzeugen Nutzungsdaten, wie Verweildauern und Aktivitatsprofile, sie produzieren Leistungsdaten aus digitalen Aufgaben, sie hinterlassen Textbeitrage in Foren und Chats. All diese Daten konnen genutzt werden, um mi…

El proyecto de investigación social como instrumento integrador de la praxis para los futuros/as trabajadores/as sociales

2015

El presente trabajo muestra los resultados de una investigación-intervención aplicada a los alumnos de cuarto curso de Grado en Trabajo Social. En este documento se articula una metodología de enseñanza colaborativa, significativa y crítica a partir de las evidencias de la práctica del Trabajo Social. Como conclusiones de este estudio se justifica el uso de la metodología Blended Learning en el espacio universitario. Se evidencia como con la participación y cooperación colectiva se favorece el desarrollo de competencias investigadoras, y se señala el proyecto de investigación social como herramienta que permite vincular las prácticas externas del alumnado con los elementos teóricos de la di…

Exploring the work in the blogosphere: the paradox of collaborative learning

2016

Amb l’objectiu de solucionar diversos problemes que sorgiren en la posada en practica d’una experiencia d’innovacio basada en la creacio d’una blogosfera, es porta a terme una investigacio educativa i qualitativa a partir de la col·laboracio docent i de les opinions de l’alumnat. A mes dels aspectes positius, es detectaren dificultats amb la gestio del treball en equipo i de familiaritzacio amb la ferramenta a les que els propis estudiants proposaren diverses solucions. Abordar aquesta circumstancia de forma col·laborativa i donant veu a l’alumnat ha permes que l’experiencia concloguera exitosament, resultant ser una bona practica educativa.

Constructivism in Science Education: The Need for a Clear Line of Demarcation

2003

Some voices have recently begun to question the constructivist positions, which have been considered the most important contribution of the last decades in science education. It could be thought then, that the“constructivist consensus” might just be a new fashion that would once again lead us back to the immovable reception model of science learning. This questions, at the same time, the idea of an advance in the field of science education towards the construction of a coherent body of knowledge.

New trends in science education

1996

I intend to review the main contributions from the impressive developments made in science education research during the last decade. These developments have made the construction of a coherent body of knowledge possible allowing us to expect a significant improvement in the science teaching/learning process. I shall refer, in particular, to the new trends in science education research, both in the domain of science learning and science teacher‐training.

Convolution-based ensemble learning algorithms to estimate the bond strength of the corroded reinforced concrete

2022

Reinforced concrete bond strength deterioration is one of the most serious problems in the construction industry. It is one of the most common factors impacting structural deterioration and the major cause of premature decadence of reinforced concrete structures. Therefore, developing an accurate model with the lowest variance and high reliability for the bond strength of corroded reinforced concrete is very important. The current work evaluates the efficiency of convolution-based ensemble learning algorithms. To address these issues, convolution-based ensemble learning models are developed using a database collected from the previous experimental studies of relative bond strength for corro…

Processing of rock core microtomography images: Using seven different machine learning algorithms

2016

The abilities of machine learning algorithms to process X-ray microtomographic rock images were determined. The study focused on the use of unsupervised, supervised, and ensemble clustering techniques, to segment X-ray computer microtomography rock images and to estimate the pore spaces and pore size diameters in the rocks. The unsupervised k-means technique gave the fastest processing time and the supervised least squares support vector machine technique gave the slowest processing time. Multiphase assemblages of solid phases (minerals and finely grained minerals) and the pore phase were found on visual inspection of the images. In general, the accuracy in terms of porosity values and pore…
