Structured online teachers’ collaboration for fostering professional development.
No full textThis work illustrates the design and the outcomes of online activities for supporting teachers’
collaboration within a professional development course for in-service secondary mathematics
teachers. For this aim specific tools from the general purposes e-learning platform Moodle have been
exploited to support virtual structured collaboration. Then the outcomes of the collaboration are
analyzed and discussed, as well as of the answers to a post-questionnaire submitted to the trainees
Emotion-based digital storytelling for risk education: Empirical evidences from the ALICE project
No full textGetting citizens prepared to emergencies, and especially children, is an essential issue which requires special attention in the educational process. Many evidences show that misconceptions about natural disaster and incorrect beliefs are often the basis for misguided actions that can lead to inefficient behaviours in case of dangerous events. Then school has a major role in the development of 'disaster-aware' citizens, since it is asked to design appropriate resources and select suitable methods able to guarantee retention and progression of the learning process. Teaching emergency preparedness involves studying several complex topics and more than some studies have shown that storytelling can be an effective method for teaching subjects that are intricate in nature. The educational technology considers research on construction of digital storytelling as an educational challenge. Digital narratives even gain noticeable importance when users' emotions are taken into account. Basing on these considerations, we propose in this work an adaptive, dynamic and narrative-based digital artefact in which emotions are used to rebalance the learners' status. We experimented this learning resource to teach earthquake preparedness in Italian secondary schools. © 2014 Inderscience Enterprises Ltd
A model for analyzing the explanatory writing of undergraduate students when solving mathematical tasks
No full textIn light of the recent interest in mathematical competencies and the ways in which students communicate their ideas, this study aims to explore how undergraduate students communicate their ideas about mathematical tasks through written texts. Forty-three first-year undergraduate students participated in this study. They were given a graph of a function and tangent line and were asked to estimate the value of the derivative at the tangent point justifying their answer. We analyzed the justification of students to the given task by referring to the cooperative principle and to the Anthropological Theory of the Didactic. For the former, we employed the four Grice maxims: Quantity, Quality, Relation and Manner. For the latter, we employed the main components of praxeologies: the type of task, the technique needed to solve the task, the technology as knowledge needed to explain the technique, and a theory as basis to justify the technology. A model of the students’ communication about mathematical ideas emerges and is described with reference to data analysis. The model sheds light on the relationship between the discourse of a student solving a mathematical task and how she performs the related problem-solving activity
Adaptive peer grading and formative assessment
No full textPeer grading is a process whereby students are required to grade some of their peers’ assignments as part of their own assignment. Peer grading is capable of improving students’ learning outcomes, metacognition and critical thinking and, at the same time, it can support formative assessment, saving teacher’s time and providing fast feedback, especially for large classes. In this paper we report the results of an experiment where a technology supported peer grading exercise has been assigned to students within a University course on calculus and linear algebra. To improve the reliability of students’ grades, several approaches have been experimented and the obtained results have been compared to grades coming from the teacher. Moreover, we attempted to understand how the peer grading task has contributed to reinforce the development of student’s explanation and argumentation processes
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
