The digitalization of education is a continuously developing process, aimed at the use of information and communication technologies. However, engineering education utilizes several forms of learning, with laboratory experiments being one of them. The use of digital learning materials (DLM) in labs is still limited due to numerous existing factors. This study investigates students' acceptance of using DLM during laboratory exercises in three universities located in Turkey, Poland, and Bulgaria. A questionnaire was prepared, and a survey was conducted among 625 learners. They were divided into eight categories, based on their engineering area and country. The survey results demonstrate that there is a strong correlation between the students' opinion on DLM and the use of DLM by their lab instructors, which means that their acceptance could be increased if more DLM are integrated in lab courses. The analysis of the questionnaire results also showed that there is a significant difference in the students' opinion on DLM, depending on the engineering area. Students of Food, Chemistry, and Electrical engineering rated the use of DLM quite high (above 4.0 out of 5), followed by the Civil engineering students with average results between 3.5 and 4.0. Respondents involved in Textile, Bio, and Machine engineering were the most skeptical (<3.5). Furthermore, their opinions covered a wide range from "Strongly disagree" to "Strongly agree."
