By downloading learning content in advance, it eliminates the need for internet communication during learning. When connected to the internet again, it synchronizes with the server, allowing the management side to check the user's learning progress, as well as the accuracy of tests and learning history.

Features of Goocus Offline

Enabling Learning in Any Environment

The device only connects to the internet when downloading content or uploading learning history. No internet connection is required during actual learning. This enables digital learning even in environments where internet connectivity is difficult.

Easy Learning Management and Content Updates

When the mobile device connects to the internet, it accesses the Goocus app server. Using the existing features of Goocus, administrators can manage the progress of learning, as well as deliver updates and new content.

Lightweight Content Suitable for Download

By reducing the data size of videos, images, and other content, we enable quick downloads to mobile devices and smooth operation during learning. Feel free to consult with us for the creation of original content as well.

Comments from Professor Mayumi Ishizuka, Hokkaido University Graduate School of Veterinary Medicine

"At the Graduate School of Veterinary Medicine, Hokkaido University, we have continued to collaborate in education and research with the University of Zambia since the establishment of the School of Veterinary Medicine. Since the academic year 2020, we have been implementing a short-term exchange program for graduate students on the theme of conservation medicine, targeting the entire Hokkaido University. Both countries are geographically distant, and due to cost and safety management considerations, the number of participating students is limited. To expand the opportunities, we have also established an online course. Goocus has been introduced since the academic year 2023, as it allows access to course materials even with minimal internet connectivity and makes it easy for instructors to manage materials. With the implementation of offline functionality in the future, we hope that students will be able to progress with their studies systematically even while staying in areas with limited network environments."

Upcoming Goocus Offline

As of April 2024, it will be ver.0.8 beta version.
In addition to the functions of Goocus, it is equipped with a download management function.
For the official ver.1.0 version, we plan to add calendar integration, test function, schedule function, etc.
