Possibilities of using mobile phones in the educational process

M-learning offers countless opportunities to develop students' key 21st century competences, such as the development of problem-solving skills, cooperation, communication skills and creativity. The aim of our research is to learn about the opinions of secondary school teachers regarding mobile devices, as well as their attitudes towards their use. The one-sample T-test and Chi-square test were used to analyse the responses to the questions in the questionnaire, and the non-parametric Mann-Whitney test was used to compare the averages of the Likert scale after testing the normality of the responses. Based on our results, it can be said that teachers take advantage of the opportunities offered by mobile phones, and a significant proportion of those interviewed regularly include them in the teaching process, enriching the lessons with the use of innovative applications. According to the conclusions of our study, there is a positive, forward-looking trend in Hungary for the integration of m-learning into the learning-teaching process, in which further training aimed at developing the digital skills of teachers can be of particular importance
