  • Interlingua: Supporting Students of Greater Region with Interlingual Educational Resources

    Agency/Program: INTERREG IV A GR (Grant 138 GR DeLux 3 2 274)
    Duration : March 01, 2014 - June 30, 2015
    Project Budget: €834 430.48/ Our Budget: €273 731.52
    Summary: Increasing numbers of European students enrol in formal (and informal) courses taught in a foreign language. From the socioeconomic perspective, EU promotes ever-growing mobility, especially when it comes to younger population (see, e.g., the "Youth on the Move" initiative and Bologna Process). From the pedagogical (and technological) perspective, new forms of learning (such as Open Educational Resources - OER and Massive Open Online Courses - MOOC) are emerging supported by new Information and Communication Technologies - ICT. For an individual foreign student who is trying to take advantage of these new learning opportunities a new set of challenges emerge. Studying a course from an unfamiliar university/program is difficult enough, but the difficulties multiply when the transition to the new course requirements is aggravated by the necessity to learn material in a foreign language, different from the language use for teaching them the course prerequisites. The main goal of this project is to organize a scalable solution to the problem of practical support for individual students studying in a foreign (FR/DE/EN) language. This goal is being achieved by means of an innovative e-learning technology providing students with relevant supplementary learning material in their mother tongue.

  • Adaptive Tutorial Feedback (ATuF) - II

    Agency/Program: DFG (Grant NA 738/10-1)
    Duration : April 01, 2011 - March 31, 2013
    Project Budget: €359 000/ Our Budget: €179 500
    Summary: The objectives of the project ATuF are the development and the empirical evaluation of adaptive and tutorial feedback components (ATuF components) and strategies. In the first phase of ATuF, apart from domain analysis and representation, we have investigated parts of the user modeling and of the diagnosis of errors. Furthermore we have developed ATuF components and examined their effects within exercises with typical errors while conducting first experiments. In the second phase we are investigating the following empirical and technological requirements for the adaptation of feedback and first forms of the real adaptation: (a) the effects of ATuF components and strategies depending on the characteristics of the exercises and the learners; (b) manual and automatic analysis/ data mining of the log files from the experiments; (c) empirically sustained and extended user modeling as basis for the adaptation of feedback; (d) extension of the competence, diagnosis as well as diagnosis of motivational and other variables; (e) empirical investigations of various dimensions of the feedback adaptation; (f) adaptation of the feedback strategies in relation to the characteristics of the exercises and the learners; (g) evaluation of the developed adaptation dimensions; (h) empirical investigation and technical requirements for the feedback and its adaptation within various types of exercises. Working on these issues is done using an interdisciplinary approach and the learning platform ActiveMath within ATuF.

  • Intelligent Support for Authoring Semantic Learning Content

    Agency/Program: EU FP7 People Programme (Grant PIIF-GA-2009-255049)
    Duration : July 01, 2010 - December 31, 2012
    Project Budget: €217 782 / Our Budget: €217 782
    Summary: The ultimate goal of the ISASLC project is to advance the state of the art in the field of authoring technologies for intelligent tutoring systems (ITS). Content and knowledge creation for ITS is a very complex procedure that requires considerable time investment and is especially demanding from the point of participating authors' expertise. This problem has long hindered the dissemination and adoption of adaptive and intelligent technologies in e-Learning. Its solution has not been possible before. But now, with recent advancements in Artificial Intelligence and Human-Computer Interaction, and corresponding development of new Web technologies we might have just enough tools and resources to take the next step towards solving this problem. The ISASLC project attempts to take this step by relying on the methods from such fields as Social Computing, Semantic Web, and Data Mining. From the practical perspective, ISASLC seek to widen the population of potential ITS authors by providing aid to inexperienced authors when it comes to error-prone and expertise-demanding authoring tasks, such as new content creation, metadata authoring, interactivity authoring, error detection and quality control. The R&D activity within ISASLC is divided into five work-packages: (1) Interactivity authoring support; (2) Collaborative authoring support; (3) Metadata authoring support; (4) Gap detection; (5) Open-corpus content discovery.

  • AdaptErrEx: Exploring the Learning Benefits of Erroneous Examples and Their Dynamic Adaptations Within the Context of Middle School Mathematics

    Agency/Program: US Dept. of Education (Grant R305A090460)
    Duration : September 01, 2009 - August 31, 2012
    Project Budget: $1 302 928 / Our Budget: $315 036
    Summary: Helping students to have a stronger conceptual understanding of mathematics is a major goal of K-12 instruction in the United States. Results of national and international assessments unfortunately show that while U.S. students perform adequately on applying procedures for standard computations, they have difficulty in problem solving that requires meta-cognitive strategies. Additionally, students in American schools consistently perform much worse in mathematics than their counterparts in many other countries. The AdaptErrEx project addressed this issue by presenting students with problems and problem solving techniques that fall outside the classroom norm. In particular, the intention was to present students with interactive erroneous examples of mathematical problems-step-by-step demonstrations of problem-solving in which one or more of the steps are incorrect. Erroneous examples are rarely used in classrooms because mathematics teachers are concerned that discussing errors may be embarrassing or make students more likely to make those errors, in behaviorist fashion. Very few empirical studies have tested the pedagogical value of erroneous examples, and no studies have explored adaptive presentation of such examples (e.g., presenting erroneous examples when a student is ready, withholding when not, providing help only when needed). The AdaptErrEx project has advanced the state of the art by developing technologies and materials to support learning of decimals through erroneous examples. In particular, it explored the learning outcomes of personalized sequencing of erroneous examples.
    My Role: Leader of the personalization work package.
  • Math-Bridge: European Remedial Content for Mathematics

    Agency/Program: EU eContentplus (Grant ECP-2008-EDU-428046)
    Duration : May 01, 2009 - January 31, 2012
    Project Budget: $3 599 964 / Our Budget: €1 425 413
    Summary: Many students enrolling into European colleges and universities lack mathematical competencies necessary for their studies, especially, in math-intensive engineering and science disciplines. This often leads to serious learning problems, and even causes students to drop out of their learning programs. The Math-Bridge project has addressed this problem by applying a range of techniques from the fields of Intelligent Tutoring Systems, Adaptive Hypermedia, Semantic Web and TEL. The result of these efforts is the e-Learning platform for bridging courses with a number of unique features. It provides access to the largest in the World collection of multilingual, semantically annotated learning objects (LOs) for remedial mathematics. It models students' knowledge and applies several adaptation techniques to support more effective learning, including personalized course generation, intelligent problem solving support and adaptive link annotation. It facilities a direct access to LOs by means of semantic search. It provides rich functionality for teachers allowing them to manage students, groups and courses, trace students' progress with the reporting tool, create new LOs and assemble new curricula. Math-Bridge offers a complete solution for organizing technology-enhanced learning (TEL) of mathematics on individual-, course- and/or university level.
