摘要

幼兒學習履歷是收集幼兒在學校的經歷，例如：閱讀書籍、玩玩具、畫畫等，收集到的資訊可分析每位幼兒興趣及未來發展等。目前收集幼兒資訊大多都是老師在幼兒身旁做觀察記錄並沒有自動化方式來收集幼兒資訊，且老師一次需照顧多位幼兒，無法即時在幼兒身旁觀察紀錄，造成資料不完整。為了解決此問題，本論文提出以物聯網為基礎建立自動化幼兒學習履歷資料收集系統之研究，使用無線射頻識別(RFID)技術來自動化收集幼兒閱讀書籍資訊，再透過Raspberry Pi以無線方式傳送資料到伺服器。老師有了本系統的幫助下，可不用隨時待在幼兒身旁做觀察記錄，系統自動收集幼兒閱讀書籍資訊，能減輕老師收集上的負擔。本研究與台灣中部某間在幼教界深耕20幾年的幼兒園一起模擬出幼兒閱覽室環境，並把系統建置在幼兒園閱覽室內，來幫助老師收集幼兒閱讀書籍資訊。本實驗共分成兩部分，第一部分是將收集幼兒閱讀書籍資訊方法與傳統收集方法來互相比較時間、即時性、錯誤率。實驗結果顯示在查詢時間方面本系統花費時間小於五秒，傳統方式需花費十秒以上，即時性方面本系統有提供即時性，傳統方法並無提供即時性，錯誤率方面本系統錯誤率低，傳統方式錯誤率高，由此可知本系統在時間、即時性、錯誤率優於傳統收集方式。第二部分是用科技接受模式 (Technology Acceptance Model, TAM)來探討使用者對於本系統接受程度，利用五個構面來設計問卷及統計分析，問卷用Google表單來提供給幼兒園老師及園長填寫。實驗結果共有2位園長及29位老師填寫，統計分析認知有用性有91.36%的幼兒園老師及園長對於本系統是有用、滿意，認知易用性有89.26%的幼兒園老師及園長對於本系統操作簡易且符合需求。未來系統可以應用在學校圖書館，透過收集到的數據來分析每位學生喜愛閱讀書籍種類，進而推薦書籍給學生閱讀。

Children Learning Records are collecting children's experience in school, such as reading books, playing toys and painting. The collected data can be analyzed to understand a child's interests and future development. The children learning record is recorded by preschool teachers from observing a child and is not collected automatically. However, teachers need to look after many children at one time and are not able to promptly record detailed observations on all the children. This results in incomplete learning record collection. In order to resolve this problem, this paper presents an automated data collecting system of children learning records based on Internet of Things (IoT), which uses the internet and the RFID technology to collect child information automatically while the child is reading. Raspberry Pi will transfer the information to a designated Server which is then stored into a database. Teachers with the help of the system do not to have to stay at the side of the child to upkeep observation records. The system automatically collects the information on what the children are reading and can thereby reduce the burden on teachers. This research is in collaboration with a preschool in central Taiwan with 20 year experience. The children's reading room environment is simulated with the system build in the reading room to help teachers collect the children's reading of books. Experiments are divided into two parts. The first part is to compare the learning recording between the traditional method and the developed for time, promptness, and error rate. Experimental results showed that the system takes less than five seconds in the time, the traditional method to spend more than ten seconds. The promptness side of the system to provide promptness, the traditional method does not provide promptness. The error rate of the system error rate is low, the traditional method error rate is high. We can see that the time, promptness, and error rate collected by the system is significantly higher than the traditional method. The second part is the use of the technology acceptance model (TAM). The questionnaire for statistical analysis is designed for the five concepts of TAM. Questionnaire is designed in Google format. Altogether two deans and 29 teachers take part in survey. Experimental results showed on Perceived Usefulness (PU) 91.36% of kindergarten teachers and director felt that the system is useful. On Perceived Ease of Use (PEOU) 89.26% of teachers and deans felt that the system was simple and fulfilled the requirements. In the future, we could set the system in the school library, for collecting readers’ data. The library can through the collected data then analyze each reader’s preference for the type of books and to recommend books to these readers.
