3. Dilemma: Children & New digital media 1. Motivation 2. Participatory Design Workshop Project Introduction + = Users’ needs, Feedback, Evaluation, Re-design with Key stakeholders

4. Overall System Architecture System Implementation LBSGamificationLearning Analytics

5. 1. Why? Our system offers a wide range of location-based learning missions Lead user to generate diverse activities based on their interest and context 2. Missions System-generated missions Location-specific missions e.g. Post about “acceleration of gravity” when you visit the Seoul National Science Museum Theme-specific missions e.g. Take a photo of differently shaped & colored fallen leaves User-generated missions Expect personalized play experiences Promote social engagement. Let’s Solve Mission To help users to learn about diverse themes in their surroundings through outdoor activities

6. Several Issues in current posting and commenting interfaces in Social Network Services (SNS) 1. Why? Not effectively support collaborative discussion about postings with photo Not efficiently facilitate learning from crowdsourced comments on the postings 2. A new post-comment interface Pin-based annotation system Marking a pin on a photo when posting to specify posting intention Locating a pin to elaborate discussion about a photo with comments Functionality Posting: Descriptions/ Tags/ Pin Commenting: - Sequence of comments: Brightness of pins - Topic of discussion: Frequency and distribution of pins - Conclusion of discussion: Comments with many ‘like’ Question Pins : Pin-based Annotation

8. 1. Gamification (Top-down vs. Bottom-up) Appendix. 1 To engage users, we have employed not only top-down but also bottom-up gamification mechanisms in our application design. Top-down mechanism : refers to pre-defined reward-based gamification strategies often called BLAP (Badges, Levels & Leaderboards, Achievements, and Points). Bottom-up mechanism : means gamification strategies promoting users’ intrinsic motivation by providing personalized play experiences and social engagement. Specially, we have focused on User-Generated Missions (UGM) to promote users’ intrinsic motivation and participation by means of bottom-up gamification approaches.
