This research paper is part of a research project that analyses the influence of socio-emotional prototype variables on the usage of innovative online learning and social networks to ensure that social media supports changing learning culture. This study aims to identify how creative and imaginative teaching methods and low-technology prototyping promote social-emotional (SE) skills development in every group of our school students. Firstly, we must test the research design feasibility and validate the research tools. Secondly, we can explore the relationships between the employed teaching methods and social-emotional skills development. The study is based on mixed methods-grounded theory methodology involving collecting qualitative and quantitative data from 104 participants. Based on grounded theory methodology, we have developed a pedagogical approach illustrating age-appropriate teaching practices for developing SE skills. Further research needs to be conducted to gain greater insight into the cross-curricular infusion of these methods and skills across different grades. The added value of this work is the exploration of innovative teaching methods exploiting age responsiveness so that children gain social-emotional benefits within low-technology learning situations. Low social capital and mental health result in an increasing amount of adolescent suicide, a significant cause of death among young people aged 15–19 years in Lithuania and Estonia, recording the highest rate of young people who take their own lives. Schoolwork pressure for boys and girls increased the most in Lithuania, whereas in Estonia and Latvia, it remains at the same level. While teaching face-to-face, teachers can facilitate students to empower social and emotional skills, adopt collaborative teaching methods and create trusting relationships. The changed dynamic social environment during COVID-19 needs a new vision of teaching and has encouraged further research algorithms of social-emotional intelligence, highlighting the idea of artificial intelligence implementation.
