Abstract
In the present study, we tried to find possible obstacles that Primary and Secondary education teachers face when managing Digital Learning Objects (DLOs) and/or Digital Simulation Tools (DST) in Science. One hundred seventy-six teachers from all over Greece answered the questionnaire. The results showed that the main reason for refusing to deal with DLOs and DSTs is the technological equipment. Also, the lack of adequate training level B 'results in about 25% of teachers not knowing the DSTs and 30% not knowing the DLOs. Factors such as the teaching experience, the specialty, the Pan-Hellenic examinations, the classes they teach, and the number of students they have per class negatively affect the teachers' attitude to get involved with the DLOs the DSTs. Finally, the negative attitude seems to be related to the lack of trust in the curriculum content as teachers prefer to search DLOs and DSTs on the internet connection. Further research with mixed methods of analysis would help to obtain satisfactory results.
