運用社群媒體或案例教學來增進專業知識學習，已在多數研究中獲得證實。本研究透過開放性問答的紀錄以及訪談對話，並以質性分析來了解大陸地區特殊教育專業工作者在利用社群媒體案例教學學習輔助溝通系統（augmentative and alternative communication, AAC）的困難之處。研究結果發現運用社群媒體案例教學對學習AAC專業目前所遭遇到的困境有以下四大範疇:一、個人認知部分（一）個人對AAC案例的文字的表達內容認知不同，完整案例在討論易受到干擾。（二）個人專業知識和相關經驗不足，會影響參與社群媒體案例教學的過程。（三）多數初次參與者表示在參與社群媒體案例教學模式時，對討論流程和AAC概念理解有困難。二、個人情意部分（一）社群媒體案例教學參與自主性高，堅持度及積極度會影響學習參與的意願及投入。（二）受限於時間安排或有限的精力，在學習過程中無法持續或是容易中斷。（三）學習者的信心度不足，會導致不敢進行發表或是對個人觀點正確度的辨識缺乏自信。三、個人技能部分（一）由於群上人數眾多，訊息量大，不知如何有效地篩選可用的資訊。（二）學習者將理論轉換為實踐有困難，且難以和實務作有效的銜接。四、外在環境部分（一）科技設備配合需求大，網路流暢度及軟件熟悉度備受考驗。最後筆者針對前述困境，嘗試提出相關建議，以期作為日後推廣社群媒體案例教學和學習AAC專業知能之改進參考。

The use of social media or case method to enhance professional knowledge learning has been confirmed in most studies. The purpose of the study was to investigate the predicaments and limitations of mainland China special education professionals to use social media with case method in learning AAC. The qualitative research method was used in this study. Based on the record of open questions and the semi-structure interviews, the researchers analyzed why the professionals had the difficulties in using social media with case method in learning AAC knowledge. According to the results of the study, the researchers obtained four difficulty domains about the professional using social media case with method learning AAC. 1. Cognitive domain (1) Each individual in the AAC case of knowledge was different and full case discussion was disturbed easily. (2) The lack of personal expertise and related experience would affect the process of participation. (3) Most of the participants did not understand the concepts of AAC because they had never been exposed to this kind of learning environment before. 2. Affective domain (1) To participate social media with case method learning needed high autonomy, persistence and positiveness. That would impact the participants’ will and investment of learning time. (2) Due to the time limit, the learning process would be interrupted any time. Also, the participants couldn’t stay focused if they started to feel tired. (3) Because of the lack of confidence in personal opinion, the participants were afraid to express themselves when discussing in groups. 3. Psychomotor domain (1) Since the community had a lot of people and tons of messages, participants did not know how to effectively extract the information from social media. (2) Participants had difficulties in converting theory into practice and communicating effectively with other professionals. 4. External environment (1) This kind of learning model needed a lot of technology including the uninterrupted network and the familiarity software. Finally, the researchers found the difficulties in learning AAC knowledge and tried to provide suggestions to resolve the problems. The results of the study could be used as the references for social media case method learning.
