Multimedia Development of English Vocabulary Learning in Primary School
In this paper, we describe a prototype of web-based intelligent handwriting education
system for autonomous learning of Bengali characters. Bengali language is used by more than
211 million people of India and Bangladesh. Due to the socio-economical limitation, all of the
population does not have the chance to go to school. This research project was aimed to develop
an intelligent Bengali handwriting education system. As an intelligent tutor, the system can
automatically check the handwriting errors, such as stroke production errors, stroke sequence
errors, stroke relationship errors and immediately provide a feedback to the students to correct
themselves. Our proposed system can be accessed from smartphone or iPhone that allows
students to do practice their Bengali handwriting at anytime and anywhere. Bengali is a
multi-stroke input characters with extremely long cursive shaped where it has stroke order
variability and stroke direction variability. Due to this structural limitation, recognition speed is
a crucial issue to apply traditional online handwriting recognition algorithm for Bengali
language learning. In this work, we have adopted hierarchical recognition approach to improve
the recognition speed that makes our system adaptable for web-based language learning. We
applied writing speed free recognition methodology together with hierarchical recognition
algorithm. It ensured the learning of all aged population, especially for children and older
national. The experimental results showed that our proposed hierarchical recognition algorithm
can provide higher accuracy than traditional multi-stroke recognition algorithm with more
writing variability
Using eye gaze data to explore student interactions with tutorial dialogues in a substep-based tutor
Lecture Notes in Artificial Intelligence 9112We used eye gaze data to investigate student interactions with tutorial dialogues in EER-Tutor. The results show that tutorial dialogues are effective as they enable students to correct their mistakes. However, some students do not take advantage of opportunities to reflect on what they have learnt. We identify several possible improvements to EER-Tutor, as well as future directions of work on using eye-tracking for on-line adaptation.Amali Weerasinghe, Myse Elmadani, and Antonija Mitrovi
