The global pandemic caused by COVID-19 has led to changes in many areas, with educational scenarios being affected. In this sense, university education has undergone significant changes owing to the impossibility of following the fully face-to-face mode of teaching. Given this situation, the general objective of this study is to analyze the university educational scenario in the context of COVID-19 and, more specifically, to identify the difficulties perceived by students. Using a mixed quantitative–qualitative methodological approach, an ad hoc questionnaire was designed, and data were collected from a sample of 238 students of the Bachelor’s Degree in Teaching during the 2020/2021 academic year. The results obtained have shown that students have experienced numerous difficulties in adapting to the hybrid teaching model. In this sense, it is worth highlighting the decrease in motivation, the feeling of loneliness, technical connection problems, and less interaction with the teaching staff and other students. The degree of satisfaction with the teaching received is also moderate. As a conclusion, it can be stated that the difficulties identified recommend the introduction of actions to improve the application of the teaching model implemented in favor of university excellence.

In recent years, interest in the application of gamification in education has increased. Gamification is intended to stimulate students' thinking through game techniques, involving them in problem solving. The main aim of this study is to implement a thematic analysis on the use of gamification in early childhood and primary students. To this end, a systematic review was conducted using the PRISMA model in the Web of Science database, following inclusion and exclusion criteria on quantitative and qualitative experimental and quasi-experimental studies that explore gamification in early childhood education and primary school. 24 studies were analyzed. The results show that the investigations are aimed at improving academic and collaborative skills and increasing motivation with positive results. Furthermore, most of the studies involve students between 10 and 12 years of age and are developed in science subjects supported by technological applications and gamified elements. In conclusion, it has been found that gamification has been applied in early childhood and primary education for many areas and objectives. Likewise, as a didactic strategy, it has brought significant improvements in academic performance, motivation and autonomy, which makes it advisable to continue deepening its application.
