Introduction and Problems • E-learning has become an integral part of digital earth. • It supports everyone who is keen to learn and get higher performance. • Every organisation or individual can easily and quickly creates e-learning content, teaching activity and suggests materials.   • Pro. is learners can access to study anywhere, and anytime. • Con. is how learners trust that the teaching activity or materials in e-learning could help them to achieve a learning outcome. Objective • To calculate a learner’s trust value in the teaching activity. • This learner’s trust value aims to help learners select the trustworthy teaching activity and material. Calculating Learner’s Trust in  Teaching Activity  Woraluck Wongse-ek, Gary B Wills and Lester Gilbert ESS Group, School of Electronics and Computer Science University of Southampton, UK Email: {wwe1g09, gbw, lg3}@ecs.soton.ac.uk Reasoning Web 2012 Summer School 3-8 Sep 2012 Learner’s Trust Calculation • In e-learning, learner states their purpose is an achieving good performance in the expected intended learning outcome (ILO) under the specific pedagogical context.  • Each learner’s trusts value and the perceived trustworthiness value of teaching activities may vary according to personal skills, experiences and knowledge.  • This skills, experience and knowledge of learner are combined to form a learner’s competence.  • So, learner’s trust value in teaching activity is calculated by the perceived trustworthiness of teaching activities from the parts learners, the expected ILO of learner and the exiting learner's competence within the specific pedagogical context and the learner’ competence of himself. • Given a set of learners A= {a1, a2, a3, …, an} and   a set of teaching activities  Act= {act1, act2, act3, …, actm} • Trust_act(an, actm,  Tw_actm, c) ≡           has(Tw_actm, actm, c, M_C) ⊃ believe(an, Tw_actm –> x) • The learner an trusts the teaching activity act m regarding the teaching activity actm has trustworthiness Tw_actm in context c and under the matching competence M_C, then an believes Tw_actm that will supports him to improve his performance to x. Conceptual of Learner's Trust Model Example of Prototype Screen • Using semantic technologies to construct  Knowledge Representation of following information.  Learner’s Competence   Intended Learning Outcome (ILO)  Material’s Rating  • Using semantic technology to support automated reasoning and draw conclusions. I want a study material for  helping  me to achieve good learning outcomes. Many “relevant” material can be found for you to choose. Which ones should I “trust” for achieving good learning outcome? I’m not sure. You need to try it yourself!  Learner  E-Learning System If you don’t know what material I can trust, how I can trust you then. How does Semantic Web Technology  help to calculate learner’s trust value? Future Work • Designing knowledge bases of competence, ILO, rating information. • Developing algorithm  Investigating effective machine learning techniques to automate ILO matching and competence matching. • Implementing prototype based on the knowledge bases and the algorithm • Testing and evaluating model
