ACKNOWLEDGEMENTS I would like to start by thanking the American people for the hospitality they have given me during the course of my stay in their country. The many special friendships I have enjoyed helped create a positive leaming environment for me. Dr. Virginia "Ginny" Felstehausen, my dissertation committee chairperson, has stayed the course with me through both interesting and difficult times, and has taught me lessons that go a long way beyond the classroom door. Her patience, understanding and unequivocal readiness to help have certainly contributed to my overall development. My sincere appreciation goes to other members of my committee: Dr. Amia Sue Couch for helping me understand the essence of research; Dr. Carmen Roman-Shriver for her numerous invaluable suggestions based on her unquestionable nutrition-dietetic work experience; and Dr. LesLee Taylor for her invaluable professional guidance that coupled with her own experience in writing helped to shape my dissertation. Special thanks and appreciation are extended to Dr. Du Feng and Dr. Pedros Hardjicostas, my statistics advisors, who provided me with technical knowledge and direction. However, these advisors are not responsible for any mistakes that may be found in this dissertation. Many thanks also go to Dr. Sue Reichelt and Dr. Lynda March who helped on various components despite their busy schedules. I extend my sincere appreciation to the govemment of Botswana for having provided fmancial assistance throughout my studies. My gratitude is also extended to various colleges/departments at Texas Tech University for generously providing fmancial support during the course of this endeavor. Specifically, I am thankful to the CoUege of Human Sciences for providing support through the college's graduate student scholarships and Phi Upsilon Omicron, the honor society of this coUege; and the Intemational Cultural Center. I also want to thank Sonja Koukel, Sandy and Roy Goodloe, Catherine and Delaine Crawford and others who supported me morally and emotionally during my studies. My appreciation also goes to Mabanza Masuka for the technical support he rendered for the presentation of the docimient. Most importantly, I want to express my iove and devotion to my husband, Nephious, who stood by his word to support me from the begirming to the end of my studies. My love and my admiration also go to my children, Selebogo, Itimieleng, and Khimibo; step-children, Harvest, Daniel, Elizabeth and Tiyedze; sisters; and all the extended family for sacrificing and allowing me to pursue and achieve my academic goal. Indeed, I am very grateful for their unconditional support and encouragement despite the distance that separated us over the years. Special thanks are also extended to my nephews George and lan, and to my fnends Seratwa and Mpaphi Kuswane, who helped my husband with the actual coUection of data.

Virtually no research had been conducted in Botswana schools to analyze the nutritional quality of meals students receive, nor had there been any research investigating the impact that participation by FCS/HE teachers in school feeding programs has on the nutritional quality of school meals. The purpose of the present study was to investigate the nutritional quality of feeding programs in junior secondary schools in Botswana, Southem Afiica. In addition, the study determined if participation by FCS/HE teachers in programs makes a difference in the quality of these meals. School meals were assessed against the Ministry of Education (MOE) and food-group national standards. The study was based on responses from 67 school food service supervisors and 125 FCS/HE teachers, randomly selected from the 206 junior secondary schools in Botswana. The school food service supervisors responded to a Menu Quality Survey instmment, adapted from a food frequency questionnaire that was designed specifically to assess the food intake of populations. This instnmient was used to obtain data pertinent to the specifíc foods and serving portion sizes offered to students in Botswana junior secondary schools. FCS/HE teachers responded to a Teacher Participation Survey instmment, developed by the researcher, to ascertain teachers' influence and positive attitudes toward school lunch. vn Results of the study indicated that students in Botswana junior secondary schools receive meals consisting of foods from the three food groups (Energy Giving, Body Building, and Protective). The majority of the boarding schools met or exceeded the MOE and the national standards for Energy Giving foods while the majority of the non- boarding schools exceeded these requirements for Body Building and Protective foods. The nutritional quality of school meals was not significantly changed by teacher participation. Findings from this study have practical implications for up-dating menu planning tools to ensure students receive nutritious meals. Findings also indicated that activities involving FCS/HE teachers in programs should be conducive to impacting the nutritional quality of the meals. vni LIST OF TABLES 1.1 The Ministry of Education Ration Scale Stipulation 5 2.1 The Botswana' s Food Group National Menu Plan Proportions' Model 40 2.2 Ministry of Education Food Group Menu Plan Model (Boarding) 41 2.3 Ministry of Education Four-Food Group Menu Plan (Non-Boarding) 42 3.1 Regional Distribution of Junior Secondary Schools in Botswana 107 3.2.
