This volume of Aula Abierta brings together ten empirical studies and systematic reviews that provide evidence-based scientific responses to two of the most pressing challenges on the current educational agenda: diversity and the impact of the digital divide. The selected papers, from the journal's miscellaneous section (not assigned to any monograph), follow a dual framework. On one hand, they examine the barriers and dynamics associated with classroom diversity, addressing school bullying among students with specific needs, gender inclusion difficulties, the teaching reality in rural centers, and the assessment of the school work environment. On the other hand, the volume analyzes the technological dimension of education, exploring family predictors of cyberbullying, teaching competence through the DigCompEdu framework, and digital adaptive behavior in young adults with intellectual disabilities. Finally, innovative methodological proposals are incorporated, such as visible thinking routines, music programs, and basic life support training, showing how innovation acts as an essential bridge to mitigate inequalities and promote an equitable school and university education.
