Outcomes of a Teaching Learning Sequence on Modelling Surface Phenomena in Liquids

2023

In this paper we discuss the effects of modelling and computer simulation activities in promoting student use of lines of reasoning useful to explain proposed or observed situations. The activities are part of a structured Teaching/Learning Sequence on surface phenomena in liquids. We outline a model of liquid based on a mesoscopic approach, examples of computer simulations students can use during the activities, and we describe the Teaching/Learning Sequence. During the pedagogical activities, students can simulate the liquid behaviour by controlling many simulation parameters, such as the interaction intensity among liquid and solid particles. The results of the analysis of student answer…

introduction – eu simulations as a multi-dimensional resource: from teaching and learning tool to research instrument

2015

Simulations, understood as complex role plays, are nowadays widely used in (university) teaching to actively engage students and promote content-specific interactive learning, understanding, and communication. There is a growing debate about the functions and benefits of simulations in the university teaching context. Simulating the EU is not yet as common as simulating the UN, but the use of EU simulations gradually increases. In this paper, we discuss several aspects of EU simulations. First, we briefly review the importance of the EU in current European politics, and to its growing complexity, which represents a challenge for teaching and studying European integration. Second, we indicat…

Dataset shift adaptation with active queries

2011

In remote sensing image classification, it is commonly assumed that the distribution of the classes is stable over the entire image. This way, training pixels labeled by photointerpretation are assumed to be representative of the whole image. However, differences in distribution of the classes throughout the image make this assumption weak and a model built on a single area may be suboptimal when applied to the rest of the image. In this paper, we investigate the use of active learning to correct the shifts that may appear when training and test data do not come from the same distribution. Experiments are carried out on a VHR remote sensing classification scenario showing that active learni…

Interactive Learning Environments (ILEs) as Effective Tools for Teaching Social Sciences

2016

Schoolteachers could enhance learning in social science courses by using teaching tools that favour a methodological approach focused on the topics' basic structure rather than on facts. An innovative system dynamics social-based ILE built with a social constructivist approach is presented here. The pedagogical futures of this ILE are then analysed. The effective impact of different instructional approaches inspired by social-based ILEs on student learning outcomes is also discussed. The ILE and the related inquiry-based instructional approach seem to help students understand fundamental concepts more easily, thus making the topic more comprehensible and helping students place the social fa…

The BioS4YOU project: how Science Education can enhance student capacity to be participatory citizens in a transforming world

Recent studies evidence the need to engage students at all levels in Science to boost the supply of a skilled scientific workforce and knowledgeable citizenry. The “Bio-Inspired STEM topics for engaging young generations” (BioS4YOU) project, funded by the European Union within the Erasmus+ KA2 Innovation program, aims to bridge the gap between the STEM national curricula (which mostly include basic contents of Science, Technology, Engineering, and Mathematics) and the needs of Z-generation students, apathetic/uninterested to basic themes, but enthusiastic in issues related to environmental, social, and health concerns. The main goal of the BioS4You project is to engage European young learne…

Open-inquiry driven overcoming of epistemological difficulties in engineering undergraduates: A case study in the context of thermal science

2014

This paper addresses the efficacy of an open-inquiry approach that allows students to build on traditionally received knowledge. A sample of thirty engineering undergraduates, having already attended traditional university physics instruction, was selected for this study. The students were involved in a six- week long learning experience of open-inquiry research activities within the highly motivating context of developing a thermodynamically efficient space base on Mars. They designed and carried out their own scientific investigations, which involved gathering information, collecting and analyzing data, providing explanations, and sharing results. A questionnaire containing fifteen open-e…

Using active learning to adapt remote sensing image classifiers

2011

The validity of training samples collected in field campaigns is crucial for the success of land use classification models. However, such samples often suffer from a sample selection bias and do not represent the variability of spectra that can be encountered in the entire image. Therefore, to maximize classification performance, one must perform adaptation of the first model to the new data distribution. In this paper, we propose to perform adaptation by sampling new training examples in unknown areas of the image. Our goal is to select these pixels in an intelligent fashion that minimizes their number and maximizes their information content. Two strategies based on uncertainty and cluster…

Acquisition of competencies with serious games in the accounting field: an empirical analysis

2018

El actual sistema de educación superior se basa en un aprendizaje activo por parte del estudiante enfocado al desarrollo de competencias genéricas y específicas. En este contexto muchos autores defienden el uso de simulaciones que favorezcan dicho aprendizaje y, los denominados «juegos serios» (serious games [SG]) se adaptan a este reto. Sin embargo, el empuje que cabría esperar por el desarrollo de las nuevas tecnologías y de la llegada de los denominados «nativos digitales» a las aulas no es coherente ni con su grado de implantación ni con la escasa investigación desarrollada sobre la efectividad de su uso. Los objetivos de este estudio son describir una experiencia docente de implantació…

2019

This research clarifies how a collaborative team teaching model (CTTM) can support both pre-service and in-service teachers’ professional development in using inquiry-based science teaching in primary schools. The data were collected via a questionnaire-based survey approach after inquiry projects implementation at public schools in four Finnish cities. In total, 98 pre-service teachers and 51 in-service class teachers were involved in the research. According to their experiences collaborative team teaching was seen as an adequate teaching approach in primary school science lessons. Both in-service and pre-service teachers experienced inquiry-based science teaching enthusiastically and rece…

An Active Learning Approach for Classifying Explosion Quakes

2022

In this work, an Active Learning approach for improving the classification of passed seismo-volcanic events is proposed. Here we study the specific case of Explosion Quakes from Stromboli Volcano versus other seismo-volcanic events, recorded as seismograms, and the use of Random Forest as a Classification method. In conformity with the active learning paradigm, the approach recalls the human intervention for the annotation of uncertain data. The uncertainty is established by the event probabilities, predicted by a trained random forest classifier. The human intervention consists of editing and relabelling the data into these main three classes: Explosion Quakes, Non-Explosion Quakes or Non-…
