El modelo constructivista y las relaciones Ciencia, Técnica, Sociedad
1992
SUMMARY The importance of the relations Science/Technology/Society with teaching and its convergence with the constructivist model in the science teaching-learning process, is shown in this paper. In the same way, the consequences to the students arisen from the lack of these relations in the daily teaching, are also shown.
Enseñanza/Aprendizaje de la ciencia versus historia de la ciencia
2018
<span>Podemos encontrar en la literatura abundantes argumentos a favor de la introducción de la historia de la ciencia en el curriculum de las asignaturas científicas de la enseñanza secundaria (Dana, 1990; Solomon, 1992). En este sentido, Nielsen y Thomsen (1990) señalan como beneficios obtenidos por los estudiantes que cursan asignaturas impregnadas de historia de la ciencia los siguientes...</span>
Teaching and Learning Chemistry with a Motivating Tool: one CLICK!
2021
The use of electronic response systems or “clickers” is a popular way to engage students and create an active-learning environment, especially within large courses of general subjects for first-year undergraduates. The present work examines with detail the methodology, the tasks and the results obtained respect to the students’ learning, participation, and engagement in the classroom. In general, students perceived that, clickers provided a significant enhancement to their learning, and teachers obtained real-time feed-back of how the concepts are assimilated or not by the students in order to quickly introduce improvements in their teaching.
Learning Corners in University Music Education: a proposal for implementation and assessment
2019
For teacher training, it is necessary to use innovative methodologies that allow students to experiment with them, as well as to obtain tools for their future work as teachers. This is true in the case of the methodology called "Learning corners", which we implemented and assessed in this research. A learning corners strategy was designed for 54 students studying for a Master's degree in Primary Education, within the music didactics module. The methodology included individual and collaborative activities in work teams. The results of the assessment revealed that this methodology promotes autonomy, motivation and learning, resulting in a useful resource for future teachers.
Proyectos educativos multidisciplinares y ayuda a la comunidad
2019
This paper relates an experience carried out at a higher education setting, specifically involving 3rd-year students in the Early Childhood Education degree programme. In relation to this, the paper presents an educational model that takes into account the need to develop ethical and social competences and gives importance to interdisciplinary education in real contexts. To this aim, all the academic modules that form part of this degree programme devote 25% of their teaching time and evaluation to the development of an interdisciplinary project. This paper will describe one of these projects, entitled "Solve a real problem", the design of which is informed by service-learning and problem-b…
Sequential Mining Classification
2017
Sequential pattern mining is a data mining technique that aims to extract and analyze frequent subsequences from sequences of events or items with time constraint. Sequence data mining was introduced in 1995 with the well-known Apriori algorithm. The algorithm studied the transactions through time, in order to extract frequent patterns from the sequences of products related to a customer. Later, this technique became useful in many applications: DNA researches, medical diagnosis and prevention, telecommunications, etc. GSP, SPAM, SPADE, PrefixSPan and other advanced algorithms followed. View the evolution of data mining techniques based on sequential data, this paper discusses the multiple …
Medical Data Mining for Heart Diseases and the Future of Sequential Mining in Medical Field
2018
Data Mining in general is the act of extracting interesting patterns and discovering non-trivial knowledge from a large amount of data. Medical data mining can be used to understand the events happened in the past, i.e. studying a patients vital signs to understand his complications and discover why he has died, or to predict the future by analyzing the events that had happened. In this chapter we are presenting an overview on studies that use data mining to predict heart failure and heart diseases classes. We will also focus on one of the trendiest data-mining field, namely the Sequential Mining, which is a very promising paradigm. Due to its important results in many fields, this chapter …
Hop: Histogram of patterns for human action representation
2017
This paper presents a novel method for representing actions in terms of multinomial distributions of frequent sequential patterns of different length. Frequent sequential patterns are series of data descriptors that occur many times in the data. This paper proposes to learn a codebook of frequent sequential patterns by means of an apriori-like algorithm, and to represent an action with a Bag-of-Frequent-Sequential-Patterns approach. Preliminary experiments of the proposed method have been conducted for action classification on skeletal data. The method achieves state-of-the-art accuracy value in cross-subject validation.
La Société française : de 1945 à nos jours
2015
International audience; Du plein emploi des Trente Glorieuses au chômage de masse, de l'explosion de la consommation aux nouvelles formes de précarité, de la démocratisation de l'enseignement aux mutations technologiques, sans oublier les métamorphoses de la famille, la montée de l'écologie... les auteurs de ce dossier dégagent ici les lignes de force qui ont façonné la société française après la Seconde Guerre mondiale. Les illustrations variées, les graphiques et les cartes qui accompagnent ces développements soulignent le passage d'un monde à l'autre.
Science Advances

River ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater than 1000 river and riparian sites. We found that Earth’s biomes have distinct carbon processing signatures. Slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes. Both the mean rate and variability decline with latitude, suggesting temperature constrai…
