The efects of peer corrective feedback trainning in face to face interaction and synchronousvideo-based computer-mediated comunication

Tesis (Profesor de Inglés para la Enseñanza Básica y Media y al grado académico de Licenciado en Educación)This quasi-experimental study was conducted in a private school, in Santiago, Chile, with four groups formed by 9th graders with the same L1 (Spanish) immersed in an EFL context. The purpose of the study was to examine ways in which the potential of peer interaction on learning is maximized. Specifically, the study examined two instructional techniques, both of which have been gaining increasing attention from second language acquisition researchers: (a) training learners how to correct each other (corrective feedback: CF), and (b) synchronous communicative interaction via video-based computer-mediated communication (SVCMC). Participants were divided into four groups depending on their experimental conditions. Group A (SVCMC+CF training) engaged in communicative peer interaction via SVCMC and received CF training. Group B (SVCMC-CF training) was given the same peer interaction tasks but did not receive any CF training. Groups C (FTF+CF training) and D (FTF-CF training) engaged in the same tasks in face-to-face in the classroom while only Group C received CF training. The intervention period lasted two weeks, consisting of four classes of 45 minutes for each of the four groups. The analysis involved (a) learners’ interactional behaviors, namely, language-related episodes, (b) their developmental outcomes with pre- and posttests focusing on past tense and locative usages, and (c) their perceptions based on exit questionnaire with close- and open-items. The results of this study reflected 3 main findings in peer interaction, corrective feedback, and SVCMC. With regard to interactional patterns (peer interaction), corrective feedback training promotes collaboration and so FTF environments, yet in SVCMC dominant patterns were more likely to arise. Meanwhile, CF training helped enhance learners’ language development as their results in the post-test were higher than in the pre-test and, in turn, SVCMC groups outperformed FTF groups. Concerning students’ perceptions, they overtly expressed positive beliefs regarding Peer Corrective Feedback and SVCMC activities. In short, clear differences were found among groups with different interventions resulting in distinct patterns, L2 development outcomes, and learner perceptions.Este estudio cuasi-experimental fue conducido en un colegio privado en Santiago de Chile, con cuatro grupos formados por estudiantes de primer año medio, cuya lengua nativa es el español. Los estudiantes estuvieron inmersos en un contexto EFL. El propósito del estudio fue examinar medios por las cuales el potencial de la interacción entre pares en el aprendizaje sea maximizado. Específicamente, este estudio examinó dos técnicas instructivas, las cuales han recibido recientemente atención paulatina de los investigadores en el campo de la adquisición de un segundo idioma: (a) capacitar a los estudiantes en como corregir a sus pares (retroalimentación), e (b) interacción comunicativa sincronizada a través de video conferencias (ICSV) mediadas por computadores. Los participantes fueron divididos en cuatro grupos según sus condiciones experimentales. El Grupo A (ICSV+ capacitación en retroalimentación) involucrado en interacción comunicativa— entre pares— a través de ICSV y recibieron instrucción en retroalimentación entre pares. Al Grupo B (ICSV – capacitación en retroalimentación) se le dio las mismas tareas, pero no recibió capacitación en retroalimentación. El Grupo C (cara a cara + capacitación en retroalimentación) y el Grupo D (cara a cara – capacitación en retroalimentación) participaron en las mismas tareas cara a cara en la sala de clases mientras que solo el Grupo C recibió capacitación en retroalimentación. El periodo de intervención fue de 2 semanas, compuesto de 4 clases de 45 min para cada uno de los grupos. Este análisis involucró (a) comportamientos interaccionales de los estudiantes, es decir, episodios relacionados con el lenguaje, (b) los resultados que reflejaron el desarrollo del lenguaje de los estudiantes fueron obtenidos mediante una evaluación previa a la intervención y otra posterior a la intervención; las evaluaciones se enfocaron en el uso del pasado simple y locativos, finalmente (c) las percepciones de los estudiantes obtenidas mediante un cuestionario de preguntas cerradas y abiertas. Los resultados de este estudio reflejaron 3 hallazgos principales en cuanto a interacción entre pares, retroalimentación, e ICSV. En cuanto a los patrones interacciónales (interacción entre pares), la retroalimentación y la comunicación cara a cara resultaron promover la colaboración, a diferencia de ICSV en la cual los patrones dominantes tuvieron más probabilidades de surgir. Mientras tanto, la capacitación en retroalimentación ayudó al mejoramiento del desarrollo del lenguaje de los estudiantes ya que sus resultados a lo largo de las evaluaciones pre y post presentaron un alza y, en consecuencia, los grupos que interactuaron a través de ICSV superaron a los grupos que interactuaron cara a cara. Tomando en cuenta las percepciones de los estudiantes, ellos expresaron abiertamente ideas positivas en cuanto a las actividades la capacitación en retroalimentación e ICSV. En resumen, diferencias claras fueron encontradas entre los grupos con diferentes intervenciones resultando en distintos patrones de interacción, resultados en el desarrollo del lenguaje, y percepciones de los estudiantes

Combining relevance information in a synchronous collaborative information retrieval environment

Traditionally information retrieval (IR) research has focussed on a single user interaction modality, where a user searches to satisfy an information need. Recent advances in both web technologies, such as the sociable web of Web 2.0, and computer hardware, such as tabletop interface devices, have enabled multiple users to collaborate on many computer-related tasks. Due to these advances there is an increasing need to support two or more users searching together at the same time, in order to satisfy a shared information need, which we refer to as Synchronous Collaborative Information Retrieval. Synchronous Collaborative Information Retrieval (SCIR) represents a significant paradigmatic shift from traditional IR systems. In order to support an effective SCIR search, new techniques are required to coordinate users' activities. In this chapter we explore the effectiveness of a sharing of knowledge policy on a collaborating group. Sharing of knowledge refers to the process of passing relevance information across users, if one user finds items of relevance to the search task then the group should benefit in the form of improved ranked lists returned to each searcher. In order to evaluate the proposed techniques we simulate two users searching together through an incremental feedback system. The simulation assumes that users decide on an initial query with which to begin the collaborative search and proceed through the search by providing relevance judgments to the system and receiving a new ranked list. In order to populate these simulations we extract data from the interaction logs of various experimental IR systems from previous Text REtrieval Conference (TREC) workshops

Collaboration scripts - a conceptual analysis

This article presents a conceptual analysis of collaboration scripts used in face-to-face and computer-mediated collaborative learning. Collaboration scripts are scaffolds that aim to improve collaboration through structuring the interactive processes between two or more learning partners. Collaboration scripts consist of at least five components: (a) learning objectives, (b) type of activities, (c) sequencing, (d) role distribution, and (e) type of representation. These components serve as a basis for comparing prototypical collaboration script approaches for face-to-face vs. computer-mediated learning. As our analysis reveals, collaboration scripts for face-to-face learning often focus on supporting collaborators in engaging in activities that are specifically related to individual knowledge acquisition. Scripts for computer-mediated collaboration are typically concerned with facilitating communicative-coordinative processes that occur among group members. The two lines of research can be consolidated to facilitate the design of collaboration scripts, which both support participation and coordination, as well as induce learning activities closely related to individual knowledge acquisition and metacognition. In addition, research on collaboration scripts needs to consider the learners’ internal collaboration scripts as a further determinant of collaboration behavior. The article closes with the presentation of a conceptual framework incorporating both external and internal collaboration scripts

Together we stand, Together we fall, Together we win: Dynamic Team Formation in Massive Open Online Courses

Massive Open Online Courses (MOOCs) offer a new scalable paradigm for e-learning by providing students with global exposure and opportunities for connecting and interacting with millions of people all around the world. Very often, students work as teams to effectively accomplish course related tasks. However, due to lack of face to face interaction, it becomes difficult for MOOC students to collaborate. Additionally, the instructor also faces challenges in manually organizing students into teams because students flock to these MOOCs in huge numbers. Thus, the proposed research is aimed at developing a robust methodology for dynamic team formation in MOOCs, the theoretical framework for which is grounded at the confluence of organizational team theory, social network analysis and machine learning. A prerequisite for such an undertaking is that we understand the fact that, each and every informal tie established among students offers the opportunities to influence and be influenced. Therefore, we aim to extract value from the inherent connectedness of students in the MOOC. These connections carry with them radical implications for the way students understand each other in the networked learning community. Our approach will enable course instructors to automatically group students in teams that have fairly balanced social connections with their peers, well defined in terms of appropriately selected qualitative and quantitative network metrics.Comment: In Proceedings of 5th IEEE International Conference on Application of Digital Information & Web Technologies (ICADIWT), India, February 2014 (6 pages, 3 figures

Division of labour and sharing of knowledge for synchronous collaborative information retrieval

Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques

Comparing inductive and deductive methodologies for design patterns identification and articulation

Design patterns offer a valuable format to communicate knowledge of successful design solutions to recurring problems. However, there is a lack of research into design patterns that differentiate the applicability of the proposed design solutions across different nations. This paper discusses inductive and deductive methodologies for analyzing qualitative data in order to identify and articulate design patterns for cross-cultural computer-supported collaborative design learning. It proposes a methodology how patterns for facilitating intercultural design education can be identified and articulated. Within this research, an inductive, deductive and comparative methodology for identifying and articulating design patterns was developed. Therein, eleven patterns for intercultural computer-supported collaboration were identified and written. This paper introduces the proposed methodology taking the design pattern “MOOD OF THE MOMENT” for example

Collaboration in the Semantic Grid: a Basis for e-Learning

The CoAKTinG project aims to advance the state of the art in collaborative mediated spaces for the Semantic Grid. This paper presents an overview of the hypertext and knowledge based tools which have been deployed to augment existing collaborative environments, and the ontology which is used to exchange structure, promote enhanced process tracking, and aid navigation of resources before, after, and while a collaboration occurs. While the primary focus of the project has been supporting e-Science, this paper also explores the similarities and application of CoAKTinG technologies as part of a human-centred design approach to e-Learning

Template-driven teacher modelling approach : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Information Science at Massey University, Palmerston North

This thesis describes the Template-driven Teacher Modeling Approach, the initial implementation of the template server and the formative evaluation on the prototype. The initiative of Template-driven teacher modeling is to integrate the template server and intelligent teacher models in Web-based education systems for course authoring. There are a number of key components in the proposed system: user interface, template server and content repository. The Template-Driven Teacher Modeling (TDTM) architecture supports the course authoring by providing higher degree of control over the generation of presentation. The collection of accumulated templates in the template repository for a teacher or a group of teachers are selected as the inputs for the inference mechanism in teacher's model to calculate the best representation of the teaching strategy, and then predict teacher intention when he or she interacts with the system. Moreover, the presentation templates are kept to support the re-use of the on-line content at the level of individual screens with the help of Template Server

Synchronous collaborative information retrieval: techniques and evaluation

Synchronous Collaborative Information Retrieval refers to systems that support multiple users searching together at the same time in order to satisfy a shared information need. To date most SCIR systems have focussed on providing various awareness tools in order to enable collaborating users to coordinate the search task. However, requiring users to both search and coordinate the group activity may prove too demanding. On the other hand without effective coordination policies the group search may not be effective. In this paper we propose and evaluate novel system-mediated techniques for coordinating a group search. These techniques allow for an effective division of labour across the group whereby each group member can explore a subset of the search space.We also propose and evaluate techniques to support automated sharing of knowledge across searchers in SCIR, through novel collaborative and complementary relevance feedback techniques. In order to evaluate these techniques, we propose a framework for SCIR evaluation based on simulations. To populate these simulations we extract data from TREC interactive search logs. This work represent the first simulations of SCIR to date and the first such use of this TREC data
