The Lone Star High School, which is part of the Frisco Independent School District located in Frisco, Texas is looking for ways to better engage and motivate students in the classroom especially since the COVID-19 pandemic has changed the way teachers teach and students learn. The problem is that Lone Star High School students lack the motivation to learn and stay engaged in the classroom setting. The purpose of this school improvement plan was to research the flipped classroom teaching model and to educate teachers through professional development about the benefits of using the flipped teaching method of instruction as a way to increase student motivation and engagement. The research gathered for the literature review was analyzed based on flipped teaching methods, teachers’ perception of flipped teaching practices, student motivation and achievement, and effective professional development practices. Based on the findings that the flipped classroom teaching methods increase student engagement and motivation a professional development plan was developed for the Lone Star High School teachers.
