It is widely adopted in the educational systems of several European countries, most notably Croatia, Slovenia, and Bosnia and Herzegovina. The system provides a centralized hub where instructional materials can be uploaded, assignments issued, grades recorded, and real‑time feedback exchanged. e‑klase is part of a broader trend toward the digitization of education, which seeks to increase accessibility, streamline administrative tasks, and enhance pedagogical effectiveness.
History and Background
Early Development
The concept of e‑klase emerged in the early 2000s as governments and educational authorities began exploring the potential of information and communication technologies (ICT) to support teaching and learning. The Croatian Ministry of Science and Education initiated a national project in 2005 to develop an integrated e‑learning environment for schools. The project, led by a consortium of universities, software developers, and education specialists, culminated in the release of the first beta version of e‑klase in 2007. The initial release focused on basic functionalities such as resource sharing and attendance tracking.
Official Adoption and Expansion
In 2009, the Croatian Ministry formally adopted e‑klase as the official platform for public primary and secondary schools. The decision was driven by the platform’s modular architecture, which allowed customization to meet specific curricular requirements. Following the adoption, a nationwide rollout was conducted in phases, beginning with pilot schools in Zagreb and later expanding to rural districts. Subsequent updates introduced new modules, including online assessment tools, discussion forums, and a parent‑teacher communication portal.
International Adoption
Slovenia adopted a derivative of the original e‑klase platform in 2011, customizing it to align with the Slovenian curriculum and language requirements. Bosnia and Herzegovina incorporated a localized version in 2014. The platform has also been trialed in several neighboring countries as part of cross‑border educational cooperation initiatives, although it remains most widely used within the aforementioned nations.
Key Concepts and Core Features
Learning Management System (LMS) Foundations
At its core, e‑klase functions as an LMS, providing a repository for learning materials, a workspace for collaborative activities, and tools for assessment. It follows a modular design, allowing institutions to enable or disable specific features based on administrative needs.
Resource Repository
The resource repository permits teachers to upload documents, multimedia files, and external links. Items can be tagged with metadata such as subject, grade level, and keyword, facilitating efficient search and reuse across classes.
Assignment and Assessment Module
Teachers can create and distribute assignments directly through the platform. The module supports various file formats and allows for grading rubrics, deadlines, and feedback mechanisms. Students submit assignments via the platform, which automatically records timestamps and generates plagiarism reports using integrated algorithms.
Attendance and Classroom Management
The attendance module records daily attendance, integrates with biometric or card‑based identification systems, and generates reports for administrators and parents. It also supports real‑time updates, enabling parents to check their child’s attendance status at any time.
Communication Tools
e‑klase incorporates discussion boards, messaging systems, and announcement features. These tools are used for asynchronous communication between teachers and students, as well as for parent–teacher correspondence. The platform also provides a notification system that alerts users to upcoming deadlines, new resources, and scheduled events.
Parent Portal
The parent portal offers access to class rosters, attendance records, grades, and school announcements. Parents can provide feedback to teachers and receive alerts regarding school closures or emergencies.
