Towards Evaluating and Modelling the Impacts of Mobile-Based Augmented Reality Applications on Learning and Engagement

Mobile augmented reality applications are increasingly utilized as a medium for enhancing learning and engagement in history education. Although these digital devices facilitate learning through immersive and appealing experiences, their design should be driven by theories of learning and instruction. We provide an overview of an evidence-based approach to optimize the development of mobile augmented reality applications that teaches students about history. Our research aims to evaluate and model the impacts of design parameters towards learning and engagement. The research program is interdisciplinary in that we apply techniques derived from design-based experiments and educational data mining. We outline the methodological and analytical techniques as well as discuss the implications of the anticipated findings.

Sport Values of Bantam, Midget and Intermediate Female Hockey Players and Their Minor Hockey Associations

The sport values of female hockey players and their minor hockey associations were explored to better inform a values-based approach for adult-managed minor hockey. Data were collected from 294 participatory HL and competitive Rep players (12-22 years of age) using the Youth Sport Values Questionnaire-2 and from 30 hockey association board members using a modified YSVQ-2. Results indicated player importance (VI) ratings for Moral (M = 4.08) and Competence (M = 4.15) values were not significantly different but were significantly higher than Status (M = 2.11) value. Significant weak relationships between age and competition level versus VI ratings were found. There were medium/ high Moral, medium/ low Competence and high/ high Status value congruence between Rep and HL Player-Board Members, respectively. Based upon the findings, girls’ minor hockey associations need to recognize the values female youth players prioritize, and ensure each is considered within a values-based decision-making approach to governance.

Social Opportunities and Individual Responsibility: The Capability Approach and the Third Way

The fashionable widespreading of Sen’s ideas coincides with a new mood in the shaping of public policies in affluent societies. In Europe indeed, an “opportunity”-based approach to social security has been implemented through the European Employment Strategy. Public action tends to rely on a procedural concern with individual opportunities or potentialities in the labour market. The underlying ethics is that individuals are then responsible to use these background opportunities in order to lead the kind of life they value most. More broadly, the discourse and practice of the so-called “Third Way” shares with the capability approach an appeal for a procedural and enabling depiction of the role of the State. The paper intends to clarify the relation between procedural and opportunity-based approaches to social justice, among them the capability approach, and these new patterns of public action. Our vision goes in the way of a yet renewed, but deeper action of the welfare state, where social agency is envisaged as the very condition of individual agency. Drawing on the various critics of mainstream equality of opportunity, two opposed approaches to responsibility are identified: on the one hand, responsibility is conceived of as i) a “luck vs. choice” fixed starting point, ii) a backward-looking conception and iii) a highly individualistic framework. On the other hand, responsibility is envisaged as i) an outcome of public policies rather than a starting point, ii) a forward-looking conception, and iii) a combined institutional-individual framework. We situate here Sen’s capability approach, as well as critics of the luck egalitarianism path. The Third Way rhetoric is assessed against both these perspectives. The issue eventually boils down to an ethical reflection on the articulation of responsibilities, and to a pragmatic and substantial concern for the content of what providing security should mean in practice.

Usages et compétence TIC en formation initiale à l'ENS d'Abidjan (Côte d'Ivoire : le cas des formateurs et des futurs enseignants

Les Technologies de l’Information et de la Communication (TIC) sont de plus en plus présentes dans toutes les sphères de la société y compris dans l’éducation. Pour favoriser des usages effectifs de ces technologies par des enseignants dans les salles de classe, il devient pertinent de s’intéresser aux usages qu’en font certains formateurs et futurs enseignants dans le cadre de la formation initiale. Ainsi, dans le contexte de la formation initiale des enseignants en Côte d’Ivoire à l’ENS d’Abidjan, l’objectif général de la présente thèse est de documenter les usages et la compétence TIC. Pour répondre à ces préoccupations, une étude qualitative exploratoire a été réalisée à l’Ecole normale supérieure (ENS) d’Abidjan en Côte d’Ivoire. Les entrevues individuelles semi-dirigées avec des formateurs (n = 9) et des futurs enseignants (n = 15) ont été analysées, en adoptant une approche méthodologique basée essentiellement sur l’analyse du contenu. Les résultats sont présentés sous forme d’articles scientifiques. La thèse tente ainsi de décrire des usages des TIC par des futurs enseignants, de dresser un profil des formateurs usagers des TIC dans le cadre de la formation initiale à l’ENS d’Abidjan. Elle veut aussi examiner les usages des TIC par des futurs enseignants, en formation initiale, pour certaines des composantes de la compétence TIC. Les résultats obtenus permettent de dresser une typologie des usages des TIC par des futurs enseignants dans le cadre de leurs activités d’apprentissage. Pour ce qui est des formateurs, trois profils d’usagers ont été dressés : 1. Les usagers de bas niveau qui font usage des TIC uniquement pour la recherche et la production de documents ; 2. Les usagers de niveau moyen qui, en plus de la recherche et la production de documents, utilisent les outils électroniques de communication dans leurs pratiques professionnelles, et font souvent usage des TIC dans leur classe ; 3. Les usagers de bon niveau qui, en plus de faire usage des outils de communication dans leurs pratiques professionnelles et d’intégrer les TIC dans leurs pratiques en classe, disposent de pages Web à but éducatif. Par ailleurs, l’analyse des discours des futurs enseignants sur les usages des TIC laisse percevoir que la compétence TIC se révèle de façon inégale à travers quatre de ses composantes. En effet, même s’ils n’ont pas une posture critique face aux TIC, ces futurs enseignants ont une conscience de leurs avantages dans le cadre de leur formation. Ainsi, ils utilisent les TIC pour communiquer, rechercher les informations, les interpréter afin de résoudre un problème, se constituer un réseau d’échanges et de formation continue. Même si l’intégration des TIC dans la formation initiale des enseignants en Côte d’Ivoire n’est pas encore effective, des formateurs et des futurs enseignants en font usage dans le cadre de la formation.

L’évolution de la motivation pour les mathématiques au second cycle du secondaire selon la séquence scolaire et le sexe

De nombreuses études sur l’évolution de la motivation pour les mathématiques sont disponibles et il existe également plusieurs recherches qui se sont penchées sur la question de la différence motivationnelle entre les filles et les garçons. Cependant, aucune étude n’a tenu compte de la séquence scolaire des élèves en mathématiques pour comprendre le changement motivationnel vécu pendant le second cycle du secondaire, alors que le classement en différentes séquences est subi par tous au secondaire au Québec. Le but principal de cette étude est de documenter l’évolution de la motivation pour les mathématiques des élèves du second cycle du secondaire en considérant leur séquence de formation scolaire et leur sexe. Les élèves ont été classés dans deux séquences, soit celle des mathématiques de niveau de base (416-514) et une autre de niveau de mathématiques avancé (436-536). Trois mille quatre cent quarante élèves (1864 filles et 1576 garçons) provenant de 30 écoles secondaires publiques francophones de la grande région de Montréal ont répondu à cinq reprises à un questionnaire à items auto-révélés portant sur les variables motivationnelles suivantes : le sentiment de compétence, l’anxiété de performance, la perception de l’utilité des mathématiques, l’intérêt pour les mathématiques et les buts d’accomplissement. Ces élèves étaient inscrits en 3e année du secondaire à la première année de l’étude. Ils ont ensuite été suivis en 4e et 5e année du secondaire. Les résultats des analyses à niveaux multiples indiquent que la motivation scolaire des élèves est généralement en baisse au second cycle du secondaire. Cependant, cette diminution est particulièrement criante pour les élèves inscrits dans les séquences de mathématiques avancées. En somme, les résultats indiquent que les élèves inscrits dans les séquences avancées montrent des diminutions importantes de leur sentiment de compétence au second cycle du secondaire. Leur anxiété de performance est en hausse à la fin du secondaire et l’intérêt et la perception de l’utilité des mathématiques chutent pour l’ensemble des élèves. Les buts de maîtrise-approche sont également en baisse pour tous et les élèves des séquences de base maintiennent généralement des niveaux plus faibles. Une diminution des buts de performance-approche est aussi retrouvée, mais cette dernière n’atteint que les élèves dans les séquences de formation avancées. Des hausses importantes des buts d’évitement du travail sont retrouvées pour les élèves des séquences de mathématiques avancées à la fin du secondaire. Ainsi, les élèves des séquences de mathématiques avancées enregistrent la plus forte baisse motivationnelle pendant le second cycle du secondaire bien qu’ils obtiennent généralement des scores supérieurs aux élèves des séquences de base. Ces derniers maintiennent généralement leur niveau motivationnel. La différence motivationnelle entre les filles et les garçons ne sont pas souvent significatives, malgré le fait que les filles maintiennent généralement un niveau motivationnel inférieur à celui des garçons, et ce, par rapport à leur séquence de formation respective. En somme, les résultats de la présente étude indiquent que la diminution de la motivation au second cycle du secondaire pour les mathématiques touche principalement les élèves des séquences avancées. Il paraît ainsi pertinent de considérer la séquence scolaire dans les études sur l’évolution de la motivation, du moins en mathématiques. Il semble particulièrement important d’ajuster les interventions pédagogiques proposées aux élèves des séquences avancées afin de faciliter leur transition en mathématiques de quatrième secondaire.

A Mono- and Multi-objective Approach for Recommending Software Refactoring

Les systèmes logiciels sont devenus de plus en plus répondus et importants dans notre société. Ainsi, il y a un besoin constant de logiciels de haute qualité. Pour améliorer la qualité de logiciels, l’une des techniques les plus utilisées est le refactoring qui sert à améliorer la structure d'un programme tout en préservant son comportement externe. Le refactoring promet, s'il est appliqué convenablement, à améliorer la compréhensibilité, la maintenabilité et l'extensibilité du logiciel tout en améliorant la productivité des programmeurs. En général, le refactoring pourra s’appliquer au niveau de spécification, conception ou code. Cette thèse porte sur l'automatisation de processus de recommandation de refactoring, au niveau code, s’appliquant en deux étapes principales: 1) la détection des fragments de code qui devraient être améliorés (e.g., les défauts de conception), et 2) l'identification des solutions de refactoring à appliquer. Pour la première étape, nous traduisons des régularités qui peuvent être trouvés dans des exemples de défauts de conception. Nous utilisons un algorithme génétique pour générer automatiquement des règles de détection à partir des exemples de défauts. Pour la deuxième étape, nous introduisons une approche se basant sur une recherche heuristique. Le processus consiste à trouver la séquence optimale d'opérations de refactoring permettant d'améliorer la qualité du logiciel en minimisant le nombre de défauts tout en priorisant les instances les plus critiques. De plus, nous explorons d'autres objectifs à optimiser: le nombre de changements requis pour appliquer la solution de refactoring, la préservation de la sémantique, et la consistance avec l’historique de changements. Ainsi, réduire le nombre de changements permets de garder autant que possible avec la conception initiale. La préservation de la sémantique assure que le programme restructuré est sémantiquement cohérent. De plus, nous utilisons l'historique de changement pour suggérer de nouveaux refactorings dans des contextes similaires. En outre, nous introduisons une approche multi-objective pour améliorer les attributs de qualité du logiciel (la flexibilité, la maintenabilité, etc.), fixer les « mauvaises » pratiques de conception (défauts de conception), tout en introduisant les « bonnes » pratiques de conception (patrons de conception).

Energy-Efficient Cluster based Routing Schemes for Static and Mobile Sensor Networks

The theme of the thesis is centred around one important aspect of wireless sensor networks; the energy-efficiency.The limited energy source of the sensor nodes calls for design of energy-efficient routing protocols. The schemes for protocol design should try to minimize the number of communications among the nodes to save energy. Cluster based techniques were found energy-efficient. In this method clusters are formed and data from different nodes are collected under a cluster head belonging to each clusters and then forwarded it to the base station.Appropriate cluster head selection process and generation of desirable distribution of the clusters can reduce energy consumption of the network and prolong the network lifetime. In this work two such schemes were developed for static wireless sensor networks.In the first scheme, the energy wastage due to cluster rebuilding incorporating all the nodes were addressed. A tree based scheme is presented to alleviate this problem by rebuilding only sub clusters of the network. An analytical model of energy consumption of proposed scheme is developed and the scheme is compared with existing cluster based scheme. The simulation study proved the energy savings observed.The second scheme concentrated to build load-balanced energy efficient clusters to prolong the lifetime of the network. A voting based approach to utilise the neighbor node information in the cluster head selection process is proposed. The number of nodes joining a cluster is restricted to have equal sized optimum clusters. Multi-hop communication among the cluster heads is also introduced to reduce the energy consumption. The simulation study has shown that the scheme results in balanced clusters and the network achieves reduction in energy consumption.The main conclusion from the study was the routing scheme should pay attention on successful data delivery from node to base station in addition to the energy-efficiency. The cluster based protocols are extended from static scenario to mobile scenario by various authors. None of the proposals addresses cluster head election appropriately in view of mobility. An elegant scheme for electing cluster heads is presented to meet the challenge of handling cluster durability when all the nodes in the network are moving. The scheme has been simulated and compared with a similar approach.The proliferation of sensor networks enables users with large set of sensor information to utilise them in various applications. The sensor network programming is inherently difficult due to various reasons. There must be an elegant way to collect the data gathered by sensor networks with out worrying about the underlying structure of the network. The final work presented addresses a way to collect data from a sensor network and present it to the users in a flexible way.A service oriented architecture based application is built and data collection task is presented as a web service. This will enable composition of sensor data from different sensor networks to build interesting applications. The main objective of the thesis was to design energy-efficient routing schemes for both static as well as mobile sensor networks. A progressive approach was followed to achieve this goal.

Design And Development Of A Named Entity Based Question Answering System For Malayalam Language

This is a Named Entity Based Question Answering System for Malayalam Language. Although a vast amount of information is available today in digital form, no effective information access mechanism exists to provide humans with convenient information access. Information Retrieval and Question Answering systems are the two mechanisms available now for information access. Information systems typically return a long list of documents in response to a user’s query which are to be skimmed by the user to determine whether they contain an answer. But a Question Answering System allows the user to state his/her information need as a natural language question and receives most appropriate answer in a word or a sentence or a paragraph. This system is based on Named Entity Tagging and Question Classification. Document tagging extracts useful information from the documents which will be used in finding the answer to the question. Question Classification extracts useful information from the question to determine the type of the question and the way in which the question is to be answered. Various Machine Learning methods are used to tag the documents. Rule-Based Approach is used for Question Classification. Malayalam belongs to the Dravidian family of languages and is one of the four major languages of this family. It is one of the 22 Scheduled Languages of India with official language status in the state of Kerala. It is spoken by 40 million people. Malayalam is a morphologically rich agglutinative language and relatively of free word order. Also Malayalam has a productive morphology that allows the creation of complex words which are often highly ambiguous. Document tagging tools such as Parts-of-Speech Tagger, Phrase Chunker, Named Entity Tagger, and Compound Word Splitter are developed as a part of this research work. No such tools were available for Malayalam language. Finite State Transducer, High Order Conditional Random Field, Artificial Immunity System Principles, and Support Vector Machines are the techniques used for the design of these document preprocessing tools. This research work describes how the Named Entity is used to represent the documents. Single sentence questions are used to test the system. Overall Precision and Recall obtained are 88.5% and 85.9% respectively. This work can be extended in several directions. The coverage of non-factoid questions can be increased and also it can be extended to include open domain applications. Reference Resolution and Word Sense Disambiguation techniques are suggested as the future enhancements

Does interpersonal behavior of psychotherapy trainees differ in private and professional relationships?

• Aim: The present study aimed to evaluate the effect of trainees’ interpersonal behavior on work involvement (WI) and compared their social behavior within professional and private relationships as well as between different psychotherapeutic orientations. • Methods: The interpersonal scales of the Intrex short-form questionnaire and the Work Involvement Scale (WIS) were used to evaluate two samples of German psychotherapy trainees in psychoanalytic, psychodynamic, and cognitive behavioral therapy training. Trainees from Sample 1 (N = 184) were asked to describe their interpersonal behavior in relation to their patients when filling out the Intrex, whereas trainees from Sample 2 (N = 135) were asked to describe the private relationship with a significant other. • Results: Interpersonal affiliation in professional relationships significantly predicted the level of healing involvement, while stress involvement was predicted by interpersonal affiliation and interdependence in trainees’ relationships with their patients. Social behavior within professional relationships provided higher correlations with WI than private interpersonal behavior. Significant differences were found between private and professional relation settings in trainees’ interpersonal behavior with higher levels of affiliation and interdependence with significant others. Differences between therapeutic orientation and social behavior could only be found when comparing trainees’ level of interdependence with the particular relationship setting. • Conclusion: Trainees’ interpersonal level of affiliation in professional relationships is a predictor for a successful psychotherapeutic development. Vice versa, controlling behavior in professional settings can be understood as a risk factor against psychotherapeutic growth. Both results strengthen an evidence-based approach for competence development during psychotherapy training.

Principle-Based Parsing

During the past few years, there has been much discussion of a shift from rule-based systems to principle-based systems for natural language processing. This paper outlines the major computational advantages of principle-based parsing, its differences from the usual rule-based approach, and surveys several existing principle-based parsing systems used for handling languages as diverse as Warlpiri, English, and Spanish, as well as language translation.

Contact Sensing: A Sequential Decision Approach to Sensing Manipulation Contact

This paper describes a new statistical, model-based approach to building a contact state observer. The observer uses measurements of the contact force and position, and prior information about the task encoded in a graph, to determine the current location of the robot in the task configuration space. Each node represents what the measurements will look like in a small region of configuration space by storing a predictive, statistical, measurement model. This approach assumes that the measurements are statistically block independent conditioned on knowledge of the model, which is a fairly good model of the actual process. Arcs in the graph represent possible transitions between models. Beam Viterbi search is used to match measurement history against possible paths through the model graph in order to estimate the most likely path for the robot. The resulting approach provides a new decision process that can be use as an observer for event driven manipulation programming. The decision procedure is significantly more robust than simple threshold decisions because the measurement history is used to make decisions. The approach can be used to enhance the capabilities of autonomous assembly machines and in quality control applications.
