Next, reference can be made to an embodiment diagram of playing teaching audio-visual content with multiple teaching events as shown in FIG. 6 .
揭露書提出的線上學習系統通過伺服器提供學習者登入並取得進行學習的教學影音內容,並由伺服器提供如圖6示意顯示的影音播放介面60,圖中顯示影音播放介面60正在播放一個教學影音內容600,下方示意顯示有一影片事件簿601,並可以縮圖與時間標註影片中在不同時刻定義的教學事件,如圖示影音片段603以及圖片605。舉例來說,當使用者通過此影音播放介面60播放教學影音內容600,當播放到定義的教學事件時,如經事件定義後得出的影音片段603,建立慢動作事件,其中設定有慢動作的播放效果,因此,當播放教學影音內容600至具有慢動作事件標籤位置時(對應某一時間),即播放慢動作的影音片段,以及一使用者介面顯示教學者輸入之補充說明文字、外部圖像與影音內容連結。圖片605示意表示為經事件定義後得出的圖片事件,顯示為教學影音內容中的其中之一截圖,當播放教學影音內容到此圖片605對應到的事件標籤位置時,即在影音播放介面60播出加上圖框與/或註解文字的圖片605。The online learning system proposed in the disclosure uses a server to allow learners to log in and obtain teaching audio and video content for learning, and the server provides an audio and
所述線上學習系統即通過建立學習事件與驗證學習成效的方法提供教學影音內容給學習者,並於學習者觀看教學影音內容時通過所述影音片段與/或圖片加強學習。The online learning system provides teaching video content to learners by establishing learning events and verifying learning results, and enhances learning through the video clips and/or pictures when learners watch the teaching video content.
根據以上實施例所描述的線上學習系統以及所提供給教學者與學習者的各種學習功能,還特別地可以評估學習者的學習狀況與學習成效,整體流程可參考圖7所示建立學習事件與驗證學習成效的方法實施例流程圖。According to the online learning system described in the above embodiments and the various learning functions provided to teachers and learners, it is also possible to evaluate the learning status and learning effectiveness of learners. The overall process can be referred to Figure 7 to establish learning events and Flow chart of method embodiment for verifying learning effectiveness.
流程圖顯示線上學習從取得由教學者上傳的教學影音內容(步驟S701)開始,教學影音內容是要提供給學習者以各種使用者裝置進行學習,接著教學者或是系統提供的智能方法可以根據教學影音內容的特徵定義至少一教學事件(步驟S703),之後,如以上實施例所述,可根據定義好的至少一教學事件自教學影音內容中建立一或多個影音片段,以及/或一或多個圖片(步驟S705)。The flowchart shows that online learning starts from obtaining the teaching audio and video content uploaded by the teacher (step S701). The teaching audio and video content is to be provided to learners for learning on various user devices. Then the intelligent method provided by the teacher or the system can be used according to the The characteristics of the teaching audio and video content define at least one teaching event (step S703). Afterwards, as described in the above embodiment, one or more audio and video clips can be created from the teaching audio and video content according to the defined at least one teaching event, and/or a or multiple pictures (step S705).
當在教學影音內容中完成設定教學事件後,即提供教學影音內容給學習者,學習者可以各式使用者裝置觀看教學影音內容,並根據教學事件在播放過程中在設定的事件標籤位置上以具有慢動作播放效果(如以正常速度的0.5倍速度播放)的影音片段或是靜態圖片加強學習(步驟S707)。其中,當完成播放具有慢動作播放效果的影音片段後,播放速度將回到正常速度;當學習者觀看經事件定義的圖片時,系統記錄事件圖片跳出顯示的持續時間,並顯示一個結束觀看的按鈕,讓學習者結束事件時可以關閉此圖片,其中,在一實施例中,若學習者沒有在系統設定的時間最低與最高門檻值內點擊按鈕以關閉事件,判斷學習者的學習狀況不佳,也就是學習時間過短與過長。因此,線上學習系統可根據學習者觀看教學影音內容的行為判斷學習者的學習狀況(步驟S709)。After the teaching events are set in the teaching audio and video content, the teaching audio and video content will be provided to the learners. The learners can watch the teaching audio and video content on various user devices, and according to the teaching events, during the playback process, the set event tag position will be displayed. Audio and video clips or static pictures with slow-motion playback effects (such as playback at 0.5 times the normal speed) or static pictures are used to enhance learning (step S707). Among them, when the video clip with slow-motion playback effect is completed, the playback speed will return to the normal speed; when the learner watches the picture defined by the event, the system records the duration of the event picture jumping out of the display, and displays a message indicating the end of viewing. button, allowing the learner to close the image when the event is completed. In one embodiment, if the learner does not click the button to close the event within the minimum and maximum time thresholds set by the system, it is judged that the learner's learning status is not good. , that is, the learning time is too short or too long. Therefore, the online learning system can determine the learner's learning status based on the learner's behavior of watching the teaching video content (step S709).
在此一提的是,上述實施例描述以慢動作事件加強學習,其中為了評估學習者是否有效學習,進一步提出評估有效學習事件與無效學習事件的時間門檻機制。舉例來說,當系統在慢動作畫面播完之後,整個系統畫面可停止繼續播放,並在畫面上浮現兩個功能按鈕,如「往下進行」以及「重看」兩個按鈕,若學習者按下「往下進行」按鈕,影片繼續播放,於結束此次慢動作事件後停止計時器,並結算得出一學習時間;若學習者選擇「重看」,系統則結算此次學習時間,並跳到此次慢動作事件之開頭,重看慢動作之影音片段,此時系統增加此慢動作事件之觀看次數,並於日後統計次數。It should be mentioned here that the above embodiments describe using slow motion events to enhance learning. In order to evaluate whether learners learn effectively, a time threshold mechanism for evaluating effective learning events and ineffective learning events is further proposed. For example, when the system finishes playing the slow-motion picture, the entire system screen can stop and continue playing, and two function buttons will appear on the screen, such as the "Go Next" and "Review" buttons. If the learner Press the "Go Next" button and the video will continue to play. After the slow-motion event ends, the timer will be stopped and a learning time will be calculated. If the learner chooses "Rewatch", the system will calculate the learning time. And jump to the beginning of this slow-motion event and re-watch the slow-motion audio and video clip. At this time, the system will increase the number of views of this slow-motion event and count the times in the future.
同理,在以圖片事件加強學習的實施例中,利用圖片事件評估學習者是否有效學習,亦可設置觀看圖片的時間門檻機制。舉例來說,在播放停格的圖片事件時,畫面顯示一個功能按鈕,如「往下進行」的按鈕,讓學習者在按下「往下進行」的按鈕繼續播放教學影片,可以通過計算這段學習時間以評估學習狀況。Similarly, in the embodiment of using picture events to enhance learning, picture events are used to evaluate whether learners learn effectively, and a time threshold mechanism for viewing pictures can also be set. For example, when playing a stopped picture event, a function button is displayed on the screen, such as a "Go Next" button, allowing learners to press the "Go Next" button to continue playing the teaching video. This can be calculated by calculating A period of study time to assess learning status.
特別的是,為了要評估學習者的學習狀況,可定義出學習事件為有效學習事件與無效學習事件的參數,包括定義一最短學習時間門檻與一最長學習時間門檻,其中,這兩個參數可為教學者與管理者依據系統運行經驗設定,亦可由學習者學習某學習事件行為經長時間統計後,加上一緩衝值,由人工或軟體所設定。判斷學習事件為有效或無效時,當學習者完成學習事件之時間大於等於最短學習時間門檻,並小於等於最長學習時間門檻,即判定為一有效學習事件,反之,則判定為一無效學習事件。In particular, in order to evaluate the learner's learning status, learning events can be defined as parameters of effective learning events and invalid learning events, including defining a minimum learning time threshold and a maximum learning time threshold, where these two parameters can It is set by teachers and managers based on system operation experience. It can also be set manually or by software after learners learn a certain learning event behavior and add a buffer value after a long period of statistics. When judging whether a learning event is valid or invalid, when the time for the learner to complete the learning event is greater than or equal to the minimum learning time threshold and less than or equal to the maximum learning time threshold, it is determined to be a valid learning event; otherwise, it is determined to be an invalid learning event.
進一步地,線上學習系統可以根據上述定義的教學事件中影片與圖片特徵設定評估學習者成效的題目。舉例來說,系統可以解析經事件定義的影音片段或圖片的內容,其中實施方式包括從影音與圖片中進行語音或文字辨識,以形成評估學習者對教學影音內容的學習成效的至少一題目。根據實施例之一,可通過伺服器中影像辨識或是語意辨識功能解析影音片段或圖片的內容,例如可應用人工智能工具(AI)、內容辨識、語義分析(semantic analysis)、重組以及正反義內容生成等軟體工具,通過一題目生成功能形成包括有一正解與至少一反解的至少一題目。Furthermore, the online learning system can set questions to evaluate the learner's effectiveness based on the characteristics of the videos and pictures in the teaching events defined above. For example, the system can parse the content of video clips or pictures defined by events. The implementation includes performing speech or text recognition from the videos and pictures to form at least one question for evaluating the learner's learning effectiveness of the teaching video content. According to one embodiment, the content of video clips or pictures can be analyzed through image recognition or semantic recognition functions in the server. For example, artificial intelligence tools (AI), content recognition, semantic analysis, reorganization, and pros and cons can be applied. Software tools such as meaning content generation generate at least one question including one positive solution and at least one negative solution through a question generation function.
因此,當完成播放教學影音內容後,系統將通過提供給學習者的使用者介面顯示經解析上述定義好的教學事件的影音片段與/或圖片得出的至少一個題目(步驟S711),要求學習者回答這些題目,因此可以根據學習者對至少一題目產生的回應驗證學習者的學習成效(步驟S713)。Therefore, after finishing playing the teaching audio and video content, the system will display at least one question obtained by analyzing the audio and video clips and/or pictures of the above-defined teaching events through the user interface provided to the learner (step S711), requiring learning The learner answers these questions, so the learner's learning effectiveness can be verified based on the learner's response to at least one question (step S713).
根據實施例,在評估學習者學習成效的方法中,主要可參考學習時間,當學習者完成某一教學影音內容的學習後,線上學習系統通過伺服器可記載學習者完成某一課程的記錄。因此,對完成課程的學習者而言,回放已經完成學習的教學影音內容時,將不執行學習時間判斷機制。According to the embodiment, in the method of evaluating the learner's learning effectiveness, the learning time can be mainly referred to. When the learner completes learning a certain teaching video content, the online learning system can record the record of the learner completing a certain course through the server. Therefore, for learners who have completed the course, the learning time judgment mechanism will not be executed when playing back the teaching video content that has been completed.
進一步地,線上學習系統將可以根據學習時間評估出學習者的學習成效。舉例來說,若學習者停留某個片段時間低於最短學習時間,且未曾通過學習成效驗證即跳出者,線上學習系統可記錄「無效學習」 。若學習者事件停留時間長於一事先定義之時間門檻,或經大數據分析所有學習者針對某教學影音內容中特定教學事件的學習時間加上所述緩衝值後,此學習者可被判定為不符合有效學習者,可判斷學習者「無效學習」。反之,線上學習系統記錄學習者為「有效學習」。Furthermore, the online learning system will be able to evaluate the learner's learning effectiveness based on the learning time. For example, if a learner stays in a certain segment for less than the minimum learning time and jumps out without passing the learning effectiveness verification, the online learning system can record "invalid learning". If the stay time of a learner event is longer than a predefined time threshold, or after big data analysis of all learners' learning time for specific teaching events in a certain teaching audio-visual content plus the buffer value, the learner can be determined to be unavailable. In line with effective learners, learners can be judged to be "ineffective learning". On the contrary, the online learning system records the learner as "effective learning".
在根據學習者針對系統提出的題目的回應評估學習者學習成效的方式中,通過線上學習系統中的人工智能工具、內容辨識、語義分析、重組以及正反義內容生成等軟體工具,從定義為教學事件的影音片段與圖片中得出題目內容。例如,先辨識圖片上的一或多個解說外框與其文字,題目的數量與內容都基於這些辨識結果而定。經語義分析後,取得其中文字意思,得出正解內容,還能將語意變更成反解,再經隨機排列與重組後形成提供給學習者回答的選擇或是非題,藉此可以驗證學習者的學習成效,最後亦可發出有效學習或無效學習的結果。In the way of evaluating learners' learning effectiveness based on their responses to questions posed by the system, software tools such as artificial intelligence tools, content identification, semantic analysis, reorganization, and positive and negative content generation in the online learning system are defined as The content of the question is derived from the video clips and pictures of the teaching event. For example, one or more explanation frames and their text on the picture are first identified, and the number and content of the questions are determined based on these identification results. After semantic analysis, the meaning of the text is obtained, and the content of the correct solution can be obtained. The semantic meaning can also be changed into the negative solution, and then randomly arranged and reorganized to form a choice or yes-or-no question for the learner to answer, thereby verifying the learner's knowledge. Learning effectiveness can also be used to determine the results of effective learning or ineffective learning.
綜上所述,根據上述線上學習系統以及建立學習事件與驗證學習成效的方法的實施內容,所提出的線上學習系統與方法有效提供教學者上傳教學影音內容,並能定義出提供學習者加強學習的影音片段與圖片,並通過伺服器中的軟體手段有效評估學習者學習狀態,並能通過從加強學習的影音片段或圖片自動得出的題目以評估學習者的學習成效。In summary, according to the implementation content of the above-mentioned online learning system and the method of establishing learning events and verifying learning effectiveness, the proposed online learning system and method effectively provide teachers with the ability to upload teaching audio and video content, and can define ways to provide learners with enhanced learning The video clips and pictures can be used to effectively evaluate the learner's learning status through the software in the server, and the learner's learning effectiveness can be evaluated through questions automatically derived from the video clips or pictures that enhance learning.
