本研究旨在探討國民中學棒球選手對於理想教練角色期望之情形，藉以提供國民中學教練作為領導球隊之參考。本研究採調查研究法，採抽樣方式進行，取樣對象為台灣地區國民中學棒球隊選手。本研究之研究工具為自編之「國民中學棒球選手對理想教練角色期望與教練角色實踐調查問卷」，共計發出100份問卷，回收81 份問卷，回收率為81.00%，有效問卷為70 份，有效問卷率為86.42%。所得資料以t 檢定、單因子變異數分析、皮爾遜績差相關進行分析。研究結果顯示，國中棒球選手對理想教練具有高度的角色期望，且認為教練實際角色實踐仍有成長空間；而國中棒球選手對理想教練的角色期望及其對於教練實際角色實踐，皆受到其在國小階段是否已為球員或高中是否規劃繼續打球，以及不同年級與球齡等變項之影響；選手對理想教練角色期望與教練實際角色實踐呈顯著負相關。 The purpose of this study was to explore the situation of role expectation of an ideal coach from baseball players in junior high school and provide further conclusions and suggestions accordingly.
