隨著高齡社會來臨，高齡學習已成為重要的議題。學習動機是觸動學習行動的根本。研究目的是探討高齡學習者參與學習活動的初始動機，以及學習動機在學習過程中的改變情形。以質性研究半結構式訪談進行資料蒐集，選取21位高齡學習者為對象。研究結果發現：1.高齡學習者的初始學習動機主要從任務導向與需求導向為出發點；2.老化及教育的制度與環境可能是影響學習動機的因素；3.學習的觀念、態度、調適、支持及愉悅感是退休者維持學習動機的方式；4.反思可能是貫穿整個學習動機的發展過程，且可引發、增強學習動機。

With the coming of aged society, older adult learning has become an important issue. Learning motivations are the foundation which initiates learning actions. This study aimed to explore older adults' initial learning motivations and their transformations in the learning process. We conducted a qualitative approach and collected data via semi-structured interviews with 21 older adult learners. The findings were as followings. 1. Older adults' initial learning motivations were driven from career tasks and needs. 2. Aging and educational systems were the critical elements which affected older adults' learning motivations. 3. The learning concepts, individual attitudes, adjustment, supports and a sense of pleasure were the elements which maintain interviewees' learning motivations. 4. Interviewees' reflections could be occurred in the learning process, and these reflections could also enforce older adults' learning motivations.
