How was education before and how is it today? Teaching methodology: Before, education was based on traditional methods such as frontal teaching and memorization. Now, a more student-centered methodology is used, encouraging active participation, collaborative learning and the use of technology. Access to information: Previously, information was limited to textbooks and printed sources. Now, with the advancement of technology, students have access to a wide range of online resources, allowing them to access up-to-date and diverse information. Focus on 21st century skills: Previously, education focused on the acquisition of theoretical knowledge. Emphasis is now placed on developing skills such as creativity, critical thinking, effective communication and collaboration, which are necessary to succeed in today's world. Personalization of learning: Previously, education followed a “one size fits all” approach where all students received the same instruction. Now, we seek to adapt learning to the individual needs of each student, providing personalized and differentiated learning opportunities. Use of technology in the classroom: Previously, technology was limited in classrooms and was used occasionally. Now, technology is regularly integrated into the teaching-learning process, facilitating access to digital resources, interactive tools and online learning platforms.
