QUALITATIVE CASE STUDY RESEARCH COMPONENTS AND STRUCTURE
OF A CURRICULUM-BASED MENTORING PROGRAM AT THE MIDDLE
SCHOOL LEVEL, GOLIGHTLY, M (1996)
Outcomes of the Study
This study has been conducted to discover the components and structure of a curriculum-based
mentoring program at the middle school level. A second purpose of the study was to discover common
traits and characteristics eighth grade mentoring students exhibit. A major outcome of this study is that
it may lead to developments in curriculum, which include mentoring programs to build strong
leadership qualities in young people. A curriculum including mentoring could successfully employ older
students to serve as positive role models for younger children. Middle school mentors would have
valuable opportunities to serve as leaders, while further building character in themselves. Younger
students in a peer mentoring program would benefit by spending time with a caring guide who shows
concern for their well being. Younger students could benefit as well, academically, as older mentors
would be available to offer them assistance and support. These mentors can fill the role of the missing
role model and caregiver for younger students who need positive examples and guidance.
From the findings in this research study, several important ideas have evolved which could help
educators interested in school based mentoring programs. Findings in this study have revealed traits
the mentoring students feel are important in service as positive role models. These traits include
responsibility, helpfulness, caring, respect for self and others, and a sense of ethics. The mentoring
program in this study was shown effective in continuing the development of these qualities in
participating students. Through findings in this study, educators will have the design and structure
needed to implement such a program within an existing curriculum. Through student participation in
this type of mentoring program, students will find opportunities to serve in their school and community
while continuing to develop effective traits such as responsibility, helpfulness, and respect.

In Conclusion
• Research is a guide to what works
• Review research with a critical eye
• Select interventions that work with your
population
• Avoid the quick fix
• Select interventions that are cost
effective
• Implement interventions as designed
