Remote collaborative multi-user informal learning experiences: design and evaluation

This paper presents a customizable system used to develop a collaborative multi-user problem solving game. It addresses the increasing demand for appealing informal learning experiences in museum-like settings. The system facilitates remote collaboration by allowing groups of learners tocommunicate through a videoconferencing system and by allowing them to simultaneously interact through a shared multi-touch interactive surface. A user study with 20 user groups indicates that the game facilitates collaboration between local and remote groups of learners. The videoconference and multitouch surface acted as communication channels, attracted students’ interest, facilitated engagement, and promoted inter- and intra-group collaboration—favoring intra-group collaboration. Our findings suggest that augmentingvideoconferencing systems with a shared multitouch space offers newpossibilities and scenarios for remote collaborative environments and collaborative learning.

Desenvolupament d’una eina per a l’escriptura de nous exercicis de l’ACME

L'ACME és una plataforma d'e-learning utilitzada a la Universitat de Girona que permet la correcció automètica d'un gran nombre d'exercicis de tipologies variades via web. Actualments'utilitza com a eina de seguiment del treball diari dels alumnes en moltes carreresi facultats de la Universitat de Girona, que els permet consolidar la matèria explicada aclasse.Actualment tots els fitxers que contenen la implementació dels exercicis definits a l'ACMEestan en format LATEXi segueixen uns formats d'escriptura concrets, no estàndards i moltsdefiits per a la seva posterior lectura i interpretació. Aquesta alta especificitat i mancad'estandardització fa difícil l'aprenentatge de l'escriptura per part dels professors que volenfer servir l'ACME. La majoria d'ells es limiten a escriure exercicis nous a partir d'exercicisantics, desconeixen per complet si amb la tipologia d'exercici que utilitzen estan fent servirtot el potencial, o no, que permet l'eina. És en aquest punt que neix aquest ProjecteFinal de Carrera amb la intenció de desenvolupar una eina que permeti facilitar, millorar iampliar la metodologia d'escriptura de nous exercicis a l'ACME.L'objectiu d'aquest Projecte Final de Carrera era desenvolupar una metodologia d'escripturad'exercicis diferent, innovadora i a l'abast de qualsevol professor per poder crear noustipus d'exercicis amb facilitat i sense haver de necessitar coneixements sobre programació

The underestimation of compliance to direct help requests explained by adaptive sampling

Helping behavior is any intentional behavior that benefits another living being or group (Hogg & Vaughan, 2010). People tend to underestimate the probability that others will comply with their direct requests for help (Flynn & Lake, 2008). This implies that when they need help, they will assess the probability of getting it (De Paulo, 1982, cited in Flynn & Lake, 2008) and then they will tend to estimate one that is actually lower than the real chance, so they may not even consider worth asking for it. Existing explanations for this phenomenon attribute it to a mistaken cost computation by the help seeker, who will emphasize the instrumental cost of “saying yes”, ignoring that the potential helper also needs to take into account the social cost of saying “no”. And the truth is that, especially in face-to-face interactions, the discomfort caused by refusing to help can be very high. In short, help seekers tend to fail to realize that it might be more costly to refuse to comply with a help request rather than accepting. A similar effect has been observed when estimating trustworthiness of people. Fetchenhauer and Dunning (2010) showed that people also tend to underestimate it. This bias is reduced when, instead of asymmetric feedback (getting feedback only when deciding to trust the other person), symmetric feedback (always given) was provided. This cause could as well be applicable to help seeking as people only receive feedback when they actually make their request but not otherwise. Fazio, Shook, and Eiser (2004) studied something that could be reinforcing these outcomes: Learning asymmetries. By means of a computer game called BeanFest, they showed that people learn better about negatively valenced objects (beans in this case) than about positively valenced ones. This learning asymmetry esteemed from “information gain being contingent on approach behavior” (p. 293), which could be identified with what Fetchenhauer and Dunning mention as ‘asymmetric feedback’, and hence also with help requests. Fazio et al. also found a generalization asymmetry in favor of negative attitudes versus positive ones. They attributed it to a negativity bias that “weights resemblance to a known negative more heavily than resemblance to a positive” (p. 300). Applied to help seeking scenarios, this would mean that when facing an unknown situation, people would tend to generalize and infer that is more likely that they get a negative rather than a positive outcome from it, so, along with what it was said before, people will be more inclined to think that they will get a “no” when requesting help. Denrell and Le Mens (2011) present a different perspective when trying to explain judgment biases in general. They deviate from the classical inappropriate information processing (depicted among other by Fiske & Taylor, 2007, and Tversky & Kahneman, 1974) and explain this in terms of ‘adaptive sampling’. Adaptive sampling is a sampling mechanism in which the selection of sample items is conditioned by the values of the variable of interest previously observed (Thompson, 2011). Sampling adaptively allows individuals to safeguard themselves from experiences they went through once and turned out to lay negative outcomes. However, it also prevents them from giving a second chance to those experiences to get an updated outcome that could maybe turn into a positive one, a more positive one, or just one that regresses to the mean, whatever direction that implies. That, as Denrell and Le Mens (2011) explained, makes sense: If you go to a restaurant, and you did not like the food, you do not choose that restaurant again. This is what we think could be happening when asking for help: When we get a “no”, we stop asking. And here, we want to provide a complementary explanation for the underestimation of the probability that others comply with our direct help requests based on adaptive sampling. First, we will develop and explain a model that represents the theory. Later on, we will test it empirically by means of experiments, and will elaborate on the analysis of its results.

Aprendizaje basado en problemas. Presentación

Esta presentación corresponde a un número monográfico que pretende proporcionar materiales para una reflexión en torno a las dificultades que presenta la introducción del ABP en la educación universitaria. Los citados materiales proceden tanto de la valoración de distintas experiencias como de la aportación teórica y se confirman plenamente con los datos empíricos procedentes de una investigación realizada con estudiantes de Derecho de la Universidad de Barcelona.

¿Cómo se lee y escribe en línea?

Se pretende averiguar, en base a datos de una investigación en curso, cómo se lee y escribe en clase cuando cada aprendiz dispone de portátil, está conectado a la red y el libro de texto es digital.

El portafolios digital como herramienta para el desarrollo de competencias transversales en el alumnado.

Partiendo de un enfoque sobre las relaciones entre las tecnologías digitales como herramientas de mediación, se analiza el papel de un caso concreto, los portafolios electrónicos, para la mejora de competencias transversales en el ámbito universitario. Los resultados indican que se obtienen mejoras, como mínimo desde la percepción de los propios estudiantes, en algunas dimensiones ligadas a la capacidad para seleccionar y organizar información, así como a la planificación del aprendizaje.
