We make being an excellent teacher easier for everyone.
It has been known for decades that teachers influence learning outcomes the most. Professor John Hattie summarized the five things that excellent teachers do differently (based on more than 500,000 scientific studies about the effects on learning outcomes):

• Depth
  Excellent teachers have deeper understanding of the learning path, the lesson content, and the current skills of their students available when teaching.
• Ownership
  Excellent teachers organize and guide challenging ownership of their students.
• Interaction
  Excellent teachers monitor the progress of their students more ‘automatically’ and provide more effective feedback.
• Personalization
  Excellent teachers guide individual learning in classroom settings.
• Involvement
  Excellent teachers are more affectively involved with students and their personal growth.
