1 Localized Iterative Design for Language Learning in Underdeveloped Regions: The PACE Framework Authors: Mathew Kam Divya Ramachandran, Varun Devanathan, Anuj Tewari, John Canny Presented by: Ken Le

2 Overview Background Main Topics –Design Challenges –Solution: The PACE Framework –Implementation and User Studies Conclusion Questions

3 What is the PACE Framework? A framework that supports flexible, rapid, and scalable development of language learning software localized for a particular community of learners. Background

4 Project MILLEE Mobile and Immersive Learning for Literacy in Emerging Economies Background

5 Why? English considered as tool for success in emerging economies Many schools in developing regions do poorly in second language education –26% of children cannot read English alphabet after 1 year –25% teacher absent rate –43% children do not attend school regularly Huge divide occurring Background

6 Video TV documentary on novel cell phone usage. “Cell Phone: The Ring Heard Around the World” Background Features parts of project MILLEE Set stage for discussion on the PACE Framework

7 The PACE Framework: Main Topics 1.Design Challenges 2.Solution: The PACE Framework 3.Implementation and User Studies

8 1) Design Challenges

9 Cultural Challenges Understanding of user’s educational baseline User’s with limited computing experience Uncommon cultural backgrounds 1) Design Challenges

10 Software Challenges Flexibility Fast Iterations Scalability 1) Design Challenges

11 2) Solution: The PACE Framework

12 The PACE Framework Layered architecture that allows for flexible, iterative, and scalable design Pattern Activity Curriculum Exercise 2) Solution: The PACE Framework

13 Curriculum Alphabet Vocabulary Images Pronunciations 2) Solution: The PACE Framework

14 Example Curriculums 2) Solution: The PACE Framework Pure content, no presentation

15 Pattern A template Interested in patterns current language learning software use to implement learning tasks 2) Solution: The PACE Framework

16 Pattern Example Receptive Phase Banana Apple Orange 2) Solution: The PACE Framework Written Word->Semantic Association

17 Pattern Example Activation Phase Banana ? Apple ? Orange ? 2) Solution: The PACE Framework Written Word->Semantic Association

18 Pattern Many patterns available Why patterns? Spend energy on other design tasks, not on reinventing the wheel 2) Solution: The PACE Framework

19 Activity 2) Solution: The PACE Framework

20 Exercises Combination of patterns, activities, and curriculums 2) Solution: The PACE Framework

21 Example: Three Exercises 2) Solution: The PACE Framework

22 Example: Two Exercises 2) Solution: The PACE Framework

23 The PACE Framework Layered architecture allows for –Flexibility Adapt to a culture or age group based on choice of curriculum, pattern, and activity –Fast Iterations Lots of reusable curriculums, patterns, and activities Modifications only need to be done at certain layers –Scalability Content specialists can focus on curriculum Teaching specialists can focus on patterns Application developers can focus on user interface Many exercises that fit various cultures and age groups may be developed based: e.g. one curriculum to many activities 2) Solution: The PACE Framework

24 3) Implementation and Case Studies

25 Implementation 35 software applications reviewed 50 patterns identified 11 patterns chosen for initial language learning 6 activities implemented 21 curricula: –alphabet, numbers, dates, time, shopping, travel, nature, social situations 3) Implementation and User Studies

26 User Study 1 Age group: 4-6 Curriculum: alphabet Exercises: 3 Pre-test –3 of 14 didn’t know alphabet –Others knew two-thirds Study Duration: 2 days 3) Implementation and User Studies

27 User Study 1 Design Iterations –Simplified feedback mechanism –Removed time limit –Introduced more animations –Added repeat sound Results –One student completes all 3 exercises –Most students complete 2 out of 3 exercises –3 exercises cover entire alphabet –No post-test 3) Implementation and User Studies correctincorrect

28 User Study 2 Age group: Curriculum: vocabulary Exercises: 12 Pre-test: -- Study Duration: 5 days

29 User Study 2 Design Iterations –Added more difficult words –More images and audio Results –Post-test gains 4.3/12 on t-test (p<0.001, std. dev =3.7) –Wrote short stories: two teams of three, two students 3) Implementation and User Studies

30 Conclusion The PACE framework is a layered software architecture that provides the ability for iterative design essential for localizing existing language learning content to unique cultures and age groups, in addition the use of patterns eases the development process yielding better learning software with positive outcomes.
