Multi-scenario modelling of learning

International audienceDesigning an educational scenario is a sensitive and challenging activity because it is the vector of learning. However, the designed scenario may not correspond to some learners’ characteristics (pace of work, cognitive styles, emotional factors, prerequisite knowledge, …). To personalize the learning task and adapt it gradually to each learner, several scenarios are needed. Adaptation and personalization are difficult because it is necessary on the one hand to know in advance the profiles and on the other hand to produce the multiple scenarios corresponding to these profiles. Our model allows to design many scenarios without knowing the learner profiles beforehand. Furthermore, it offers each learner opportunities to choose a scenario and to change it during their learning process. The model ensures that all announced objectives have enough resources for acquiring knowledge and activities for evaluation

Authoring of Adaptive Single-Player Educational Games

Digital Educational Games, as one of the most important application areas of Serious Games, combine positive properties of digital games, such as strong motivation for players and inherent learning processes, with educational methods and technologies. Adaptive algorithms allow such games to be aligned automatically to the needs of different players, thereby increasing the learning efficacy. However, educational games are among the most complex game production endeavors, since they are often faced with small budget on the one hand and special requirements with impacts on all aspects of game development, from design through programming to asset production, on the other. Authoring tools have been successfully created and used in fields related to Serious Games and educational games, including e-Learning, multimedia, interactive storytelling and entertainment games. These tools incorporate parts of the production workflows in their respective areas and allow all authors, including non-programmers, to create applications. While it appears beneficial to create authoring tools for educational games, we find that authoring tools for educational games have to account for the higher complexity and interactivity of games compared to other forms of multimedia and that they have not been researched thoroughly in the past. These challenges are addressed in this thesis by presenting a concept for an authoring tool for adaptive educational single-player games that accounts for the specifics of educational game development. Major results are an educational game description model, concepts for adaptive control of educational games and author support mechanisms specifically for adaptive educational game authoring. These concepts are implemented in the authoring tool "StoryTec", which is validated in the course of a set of evaluation studies. The novel features of StoryTec include the specific support for adaptive educational games, a concept for structural and interaction templates shown to increase the efficiency and effectiveness of the authoring tool, as well as the support for collaborative work. It builds the foundation for a number of current and future research and development projects, including the extension towards authoring of multiplayer games, and is tested and used by over 120 members of an open community

Collaborative Game-based Learning - Automatized Adaptation Mechanics for Game-based Collaborative Learning using Game Mastering Concepts

Learning and playing represent two core aspects of the information and communication society nowadays. Both issues are subsumed in Digital Education Games, one major field of Serious Games. Serious Games combine concepts of gaming with a broad range of application fields: among others, educational sectors and training or health and sports, but also marketing, advertisement, political education, and other societally relevant areas such as climate, energy, and safety. This work focuses on collaborative learning games, which are Digital Educational Games that combine concepts from collaborative learning with game concepts and technology. Although Digital Educational Games represent a promising addition to existing learning and teaching methods, there are different challenges opposing their application. The tension between a game that is supposed to be fun and the facilitation of serious content constitutes a central challenge to game design. The often high technical complexity and especially the instructors' lack of control over the game represent further challenges. Beyond that, the distinct heterogeneity of learners who often have different play styles, states of knowledge, learning speed, and soft skills, such as teamwork or communication skills, forms a pivotal problem. Apart from that, the vital role of the instructor needs to be taken into account. Within the scope of this dissertation, the problems mentioned above are analyzed, concepts to solve them introduced, and methods developed to address them. The first major contribution contains the conceptualization of a framework for adaptation of collaborative multiplayer games as well as for the control of those games at run-time through an instructor using the Game Master principle. The core concept hereby addresses the design of a model to represent heterogeneous groups and to represent collaborative Serious Games. Based on that, a novel concept for adaptation of collaborative multiplayer games is developed, implemented, and evaluated. Automatic recognition and interpretation of game situations, as well as determination of the most well suited adaptation based on the recognized situations, is a major challenge here. Further, a concept is developed to integrate an instructor in a meaningful way into the course of the game, giving him/her the necessary resources to recognize problems and to intervene and adapt the game at run-time. Therefore, it will be taken into account that the elaborated concepts are applicable in a generic way independent of the underlying game. The second major contribution of this work is the conceptualization and design of a simulation of players and learners in a collaborative multiplayer game that behave realistically based on a player, learner, and interaction model. This is supposed to enable an evaluation of the adaptation and Game Mastering concepts using freely configurable player and learner types. The concepts introduced and developed within this thesis have been thoroughly evaluated using a twofold approach. As a test environment, a collaborative multiplayer Serious Game was designed and implemented. Within that simulation environment, the developed Game Mastering and adaptation concepts were assessed and tested with large sets of virtual learners. Additionally, the concepts were evaluated with real users. Therefore, two different evaluation studies with a total of 60 participants were conducted. The results of the conducted evaluations help to broaden the areas of application of Serious Games as well as to improve their applicability, hence raising acceptance among instructors. The models, architectures, and software solutions developed within this thesis thus build a foundation for further research of multiplayer Serious Games

The Big Five:Addressing Recurrent Multimodal Learning Data Challenges

The analysis of multimodal data in learning is a growing field of research, which has led to the development of different analytics solutions. However, there is no standardised approach to handle multimodal data. In this paper, we describe and outline a solution for five recurrent challenges in the analysis of multimodal data: the data collection, storing, annotation, processing and exploitation. For each of these challenges, we envision possible solutions. The prototypes for some of the proposed solutions will be discussed during the Multimodal Challenge of the fourth Learning Analytics & Knowledge Hackathon, a two-day hands-on workshop in which the authors will open up the prototypes for trials, validation and feedback

Multimodal Challenge: Analytics Beyond User-computer Interaction Data

This contribution describes one the challenges explored in the Fourth LAK Hackathon. This challenge aims at shifting the focus from learning situations which can be easily traced through user-computer interactions data and concentrate more on user-world interactions events, typical of co-located and practice-based learning experiences. This mission, pursued by the multimodal learning analytics (MMLA) community, seeks to bridge the gap between digital and physical learning spaces. The “multimodal” approach consists in combining learners’ motoric actions with physiological responses and data about the learning contexts. These data can be collected through multiple wearable sensors and Internet of Things (IoT) devices. This Hackathon table will confront with three main challenges arising from the analysis and valorisation of multimodal datasets: 1) the data collection and storing, 2) the data annotation, 3) the data processing and exploitation. Some research questions which will be considered in this Hackathon challenge are the following: how to process the raw sensor data streams and extract relevant features? which data mining and machine learning techniques can be applied? how can we compare two action recordings? How to combine sensor data with Experience API (xAPI)? what are meaningful visualisations for these data

Comparing two CbKST approaches for adapting learning paths in serious games

International audienceCompetence-based Knowledge Space Theory (CbKST) is considered a well-fitting basis for adapting Serious Games (SGs). CbKST relies on the domain model associated to a given SG to infer the so-called competence structure. However, building such a model can be time-consuming and a tough task for experts. We propose another approach to overcome this issue by considering the Q-Matrix that contains the mapping between the SG activities and the addressed competences. We compare the two approaches, one based on the domain model and the other on the Q-Matrix, in three SGs. We apply both approaches to two SGs, while in a third one, we apply only the Q-Matrix approach since no domain model is available. The main findings when comparing both approaches refer to the issues derived from the generated competence structures and the definition of competences at a suitable granularity level. This exploratory work can provide meaningful insights when applying CbKST for adapting SGs
