In today’s modern world, the role of the teacher has significantly evolved. Teachers are no longer the source of knowledge nor the center of learning in the classroom; instead they are one vital figure in designing modern learning environments. This modern learning environment constitutes engagement, adaptability, critical content and effective use of technology.

In my time as a student, classroom instruction was didactic where the teacher is the source of knowledge and we are forced to listen actively. Today, imparting knowledge is different. We need to captivate students' interest first, various teaching strategies need to be emerged. We need to engage with the students more and help them explore solutions on their own or in their group. Engaging with the students means we need our lesson relevant and interactive and let them understand the value of what they are learning.

Aside from engagement, critical thinking is much needed in this modern world. As I observe, students in my area are losing the skills in critical thinking. They depend much on what social media feeds them without questioning the authenticity of it. As educators we need to develop these skills by encouraging them to ask questions and think deeply. For example during discussions in current events, teachers can ask students to have a varied perspective on the matter. This method not only enhances critical thinking but also prepares students for the complex issues they will face in their lives and careers.

Aside from knowledge, technology teaches adaptability. Teachers should adapt to these tools of learning, During pandemic teachers and students are forced to adopt new ways of learning using online platforms. Online platforms ensure continuity in education and expand learning outside the schools. Students must adapt to these modern tools as well as the teacher's role in guiding students through unexpected changes.

Lastly, diversity of learning must also be addressed in designing their learning environment. Different instructions must be employed to suit the learning style of the learners, This makes the learning more personalized.

In conclusion, teachers are important in creating modern learning environments that promote engagement, critical thinking, and adaptability. By leveraging technology and effective pedagogy, they can address the diverse needs of learners, preparing them for the challenges of the future.
