The technical and technological advancements of the past 20 years have brought the use of digital devices and internet-based software solutions to the fore in education too. The advent of these technologies and more recently covid have revolutionized the industry.
The role of distance learning - especially in higher education and vocational training - has grown exponentially due to the significant spread of broadband networks, high-quality and high-compression media coding algorithms and target hardware. In 2020 the educational environment has transferred globally from the classrooms to an online space and switching to digital education has led to a radical increase considering the proportion of online classes, lectures and courses across the entire educational vertical.
One of the major benefits of recording that is essential in case of distance learning is the possibility of replaying the lectures. The reproducibility of the delivered curriculum provides an opportunity for students to fulfill their out-of-school responsibilities without these activities being at an expense of their educational progress. Reviewing recorded courses can greatly contribute in preparation for exams, understanding complex subjects and at-home learning in general.
The centralized recording of synchronous distance learning also provides an opportunity for quality evaluation of online lectures. Institutions can grade virtual lessons in terms of content, pedagogy, methodology and technology. Such quantitative and qualitative indicators could be: the proportion of the planned and actually taught lessons, time management, the evaluation of teaching methods, student activity, etc.
The rate of student participation can be also monitored via the institutional level of recording distance learning. Due to metadata the system also serves as an “automatic catalog“, which relieves the instructor of administrative tasks.
The centralized recording of online courses also ensures the transparency of the operation of the institution. Especially in public education, it is an emerging demand from the parental side to gain insight into school processes. The scenario of distance learning provides an opportunity for the performance and behaviour of the child -and the teacher for that matter, to be transparently traceable.
Another great additional benefit of recordings is the possibility of transcribing. Transcriptions enable users to search for specific information quickly, and generate lecture notes via exporting the transcribed delivered curriculum.
Nowadays it is critical for students and for working individuals participating in distance learning programs or MOOCs in general, that courses are recorded and available online after class.
However, the rudimentary recording functions of commonly popular video conferencing systems (Microsoft Teams, Google Meet, Cisco WebEx, Zoom) are not able to completely fulfill the aforementioned needs due to the following:
- Recording can be scheduled to an extent, therefore record generation usually depends on the lecturer.
- Recorded media files can only be managed manually.
- Post-processing options of recorded materials (e.g. transcribing) are limited.
- Centralized sharing of recorded lectures is not fully possible due to the absence of built-in sharing platforms.
These systems can only record their own video conferences. If an institution uses several systems, the difference of the recorded file formats can cause unnecessary difficulties. All the above reduces workflow efficiency, furthermore the lack of a separate sharing server makes the publication and the update of recorded interactions more demanding.
CARIN LectureCorder is a centralized and vendor-independent media recorder, transcriber and sharing application that fully meets the aforementioned demands of synchronous distance learning. It provides a complete and sophisticated solution from beginning to end, including organizing, execution and post-processment.
Software Components of CARIN LectureCorder:
The Organizer module contributes to the delegated organizer’s efficiency by facilitating the process of associating the audience with the lecturer and the tools and resources necessary for online presentation. The automated organizing platform of Outlook integrated with the CARIN system can optimize efficiency and the overall workflow.
A recorder is an IT solution that can be connected with various video conferencing systems commonly used in higher education, such as Microsoft Teams, Zoom or Cisco WebEx, by recording the interaction between the presenter and the participants while also recording the additional media shared during the online lecture, for example background projections, PowerPoint presentations or even handwritten texts and any kind of image or document.
The sharing function provides secure access to recorded materials that the audience is entitled to review or download and export via a controlled and interactive environment. Shared recordings are edited materials, which contain searchable and interactive inserts and are also suitable for subsequent offline group learning sessions. The CARIN Publishing Server provides a secure and traceable way to share recorded interactions among various members of the organization via a simplified easy-to-use web interface.
During the processing of the recorded media, it is necessary to put the received media channels together in a way that is the most optimal for the audience while working with the recorded material later. CARIN’s state-of-the-art, automated multi-transcoding feature makes this possible via transcription and making recordings downloadable. Research results have shown that audience engagement is much more intense if they not only see static content but also have the opportunity to participate interactively in the lectures. With post-process features such as emotion detection and transcription generation, the utilization of data - just as in case of call centers - can greatly contribute to future developments and workforce optimization.
