Correct Answer - Option 3 : Statements 1 and 2 are correct
Teachers provide the education that improves the quality of life, therefore bringing so much to both individuals and society as a whole. Teachers increase the productivity and creativity of students and therefore, of future workers. So, it is necessary that a teacher needs to change his behaviour and attitudes as per the needs of society. For example, for changing the globalizing world, the role of the teachers is essential to improve sustainable education. At the same time, inspiring and guiding the students in increasing employability skills with digital tools is the prerequisite for a teacher. Thus a teacher in the twenty-first century will be a digital teacher.
Students come to the classroom with a broad range of pre-existing knowledge, skills, beliefs, and attitudes, which influence how they attend, interpret and organize incoming information. Since new knowledge and skill is dependent on pre-existing knowledge and skill, knowing the background of the students is a prerequisite for teaching. Understanding your students' background helps to provide them with quality learning opportunities.
Therefore statements 1 and 2 are correct.
