Flipped Classroom Strategy

A "Flipped classroom" is an instructional strategy and a type of blended learning focused on student engagement and active learning, giving the instructor a better opportunity to deal with mixed levels, student difficulties, and differentiated learning styles during in-class time.

Flipped Classroom Benefits For Students 

A student-centered approach to teaching shifts the focus from the teacher's needs to the student's. And this is what the flipped classroom model supports:

1. When students watch or listen to lectures at home, and then solve problems and apply the new knowledge in the classroom, they get less frustration with their homework.
2. When they don't understand a new concept, they can ask questions and get immediate targeted answers.
3. The time spent in the classroom becomes not enough for all the conversations and collaboration that inevitably spur from exploring subjects in a deeper manner.
4. Last but not least, students who are absent due to illness, too long a commute, or any other reason, can catch up with their peers faster and easier with the flipped classroom model than with the standard one.

Flipped Classroom Benefits For Teachers 

1. When students come prepared to class, there's little to no need for teachers to address content related questions. Instead, they can support students in better understanding the concepts through practical application.
2. Once a lecture is done, it can be reused as many times as the teacher wants, until the content becomes outdated. But H2O will always be the symbol of water, the same as Alaska will always be the biggest US state in terms of area.
3. The flipped classroom gives more freedom to teachers to decide upon how much time to spend with each student. Struggling students, great performers, introverted kids, and extroverted ones can get the attention each of them needs.
4. Last but not least, it offers more transparency for parents, who will know exactly what their kids are preparing for at school. This can also improve the communication between parents and teachers.
