Video Question Answering on Screencast Tutorials

Wentian Zhao, Seokhwan Kim, Ning Xu, Hailin Jin
2020 Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence  
This paper presents a new video question answering task on screencast tutorials. We introduce a dataset including question, answer and context triples from the tutorial videos for a software.  ...  An one-shot recognition algorithm is designed to extract the visual cues, which helps enhance the performance of video question answering.  ...  The accuracy on the development set was calculated after each epoch, and then the best model was selected from the first 100 epochs for the final evaluation on the test set.  ...

Improving learning transfer from stencils-based tutorials

Kyle J. Harms, Jordana H. Kerr, Caitlin L. Kelleher
2011 Proceedings of the 10th International Conference on Interaction Design and Children - IDC '11  
In this paper, we describe the formative development and evaluation of on-request stencils, an interaction technique that both prevents children from making errors within a tutorial and significantly improves  ...  In a study comparing tutorial performance, task performance, and attitudes, we found that users of on-request stencils successfully completed 47% more transfer tasks than users of persistent stencils.  ...  Over the course of the tutorial, users create a new method, add basic method calls to the new method, and call the new method from the program's main method.  ...

Student Engagement with Online Tutorial: A Perspective on Flow Theory

Paulus Insap Santosa
2015 International Journal of Emerging Technologies in Learning (iJET)  
The challenge and skill must be at the same 'height' in order for them to immerse with online tutorial activities. Several aspects will be considered as challenge and skill.  ...  One challenge under the scrutiny is the page length used to present course materials. The length of tutorial presented in an online tutorial portal varies depending on its topic.  ...  Zhang and von Dran [39] proposed a two-factor model for Website design and evaluation. It comprised motivators and hygiene factors.  ...
