The purpose of this EPP is to develop a plan for changing the mindset of a large number of Haddonfield Memorial High School (HMHS) students from a fixed mindset to a growth mindset. HMHS is by most conventional measures a high performing school. Typically 100% of the students graduate with 96% of the students attending two or four year colleges and universities. Despite the apparent academic success of HMHS students, many students at HMHS may not be performing to the learning levels they are capable of due to the student belief that greater or different effort will not result in improved learning success. Chapter 1 further establishes that this student conviction may be due to HMHS students believing and accepting that academic achievement is due to their innate ability and not their learning effort. Professor Carol Dweck describes this situation as one where students tend to have a fixed mindset instead of a growth mindset. Chapter 1 also shows that the HMHS faculty is committed to the belief that all students at HMHS can do well and that greater student effort will enhance student learning. Chapter 2 proposes a plan to help a large number of students at HMHS develop a growth mindset. The proposed plan works within the ethos of the school to help minimize anticipated resistance to the plan by faculty, students, administration, and parents. Chapter 3 systematically describes the leadership strategies and skills required to have the plan in Chapter 2 become part of the everyday operation of the school. With full implementation of the plan it is anticipated that more students at HMHS will possess a growth mindset allowing them to achieve to their fullest potential.
