САЖЕТАК /ABSTRACT:
This paper presents a technical evaluation of the DigitalDialogue web application, designed to support simultaneous interaction between one teacher and multiple students in face-to-face teaching. The research is based on a laboratory analysis conducted under controlled conditions without real students; instead, simulated users (Apache JMeter) were used to imitate the process of sending questions by the teacher and short repeated answers by students. The following key variables were measured: average and maximum response time, number and percentage of HTTP errors, number of successful transactions per second, system throughput, and CPU consumption under three load conditions: 30, 100, and 200 simulated students. The results indicate that DigitalDialogue maintains a low error rate and acceptable response time even with a large number of simultaneous users, suggesting that digital technology, through a properly designed system, can provide reliable technical support for digitally enhanced interaction within asymmetric classroom communication.
