The study aims to present the effects of ICT and multimedia-based tools and methods [Augmented reality (AR) and the HY-DE model] in ESP classes at the Faculty of Law Enforcement, Ludovika University of Public Service (hereinafter: LUPS). The classroom research (2021/2022) focused on the added value of the technologies used in the terms of students’ performance and Flow-state. In the study groups the teaching material was supported with the ICT-based tools and methods (study group 1 – HY-DE model & AR; study group 2 – AR), whilst in the control group, it was carried out in a traditional way without ICT tools. We assumed that the ICT-supported lessons enhance the students’ performance and Flow-state during the teaching & learning process. The measurement tools were (1) pre – and post-vocabulary knowledge tests; (2) a flow test that measures the students’ Flow-state. The first results show a significant difference between the study and control groups (ANOVA **p<0,005). It means that the students perceived the process of the learning material supported by technologies as a challenge and learning was stored as an experience. «TKP2021-NKTA-51 has been implemented with the support provided by the Ministry of Culture and Innovation of Hungary from the National Research, Development and Innovation Fund, financed under the TKP2021-NKTA funding scheme».
