你為課堂錄影作好準備了嗎？
「演講錄影系統」泛指老師攝錄課堂時所運用的科技，而這科技已日漸被廣泛使用，成為傳統課堂以外，學生自行訂定學習節奏的工具。採納「反轉課堂」的概念，學生在上課前可觀看片段，預習課堂資料，課後更可重溫課堂內容。製作教學錄像時，老師可能會問：「在鏡頭前授課時，有甚麼有效的演示技巧呢？」
回應以上提問，教學中心於二月初誠邀演員何遠東先生(阿東)前來主持「提升演講錄影時的演示技巧」工作坊。此工作坊旨在透過提升老師的演示技巧和豐富他們對製作教學錄像的知識，從而增加老師對攝錄課堂的信心。
阿東與參加者分享他對錄像拍攝的經驗和心得。

根據阿東所說，錄像製作雖然簡單有趣，但要改變老師對拍攝錄像的心態，就一點也不容易。有些老師期望太高，以為拍攝一次就可完成整個過程，這個想法給他們徒添壓力。阿東建議，老師可把攝錄過程分成幾部份，每次拍攝一個片段，然後運用剪接技術，連接片段成為連貫的錄像節目。即使是資深演員，重拍亦非常普遍。所以，若須重拍，老師既不用尷尬，也無須自責。大家只管把同一片段拍攝兩三回，選取最好的一個就行了。

培養好老師的心理狀態後，阿東繼續分享其他心得：
服飾及化粧：服飾與化粧必須配合教學主題。例如：拍攝廚務課必須穿著廚師服飾。配合簡單的化粧能幫助突顯精明的形象。老師應避免穿著跟背景顏色相近的衣服，以免未能清楚突顯老師影像。
措詞及語氣：年青人喜愛生動的措詞及語氣，老師可善用廣東話和英語的俗語作對白。說英語對白時，應少用被動句式，以免給人太嚴肅的感覺。
面部表情和身體語言：老師可能忘記面部表情和身體語言在鏡頭前的放大效果。例如：一點污漬即引人注目，揮一揮手可令人眼花撩亂。所以，老師必須留意服飾、小動作和動作幅度。如要強調論點，只須輕輕點頭便可。
所謂熟能生巧，拍攝錄像亦不例外。阿東鼓勵老師：「攝錄課堂有助發現你的小動作，從而找出可以改善之處。盡情享受吧！拍攝教學錄像既有趣，又有意義。」
各位老師，你為課堂錄影作好準備了嗎？
參加者於工作坊裡有機會練習錄像拍攝。

Are You Ready for Lecture Capture?
Lecture capture is a broad term describing any technology that allows teachers to record their seminars and lectures and make it available digitally. It is gaining popularity as it has been widely used as a means to provide self-paced learning outside traditional classrooms. It also facilitates flipped learning and enables students’ self-study by previewing the lecture videos before the lesson or reviewing them afterwards. In producing such educational videos, teachers may ask, “What are the effective presentation skills for delivering the lecture through the camera lens?”

In response to this question, Centre for Learning and Teaching (CLT) invited Mr Ho Yuen Tung, Anthony, a performer to host a workshop on “Enhancing Your Presentation for Lecture Capture” in early February. This workshop aimed to prepare teachers for lecture recording in a more confident manner by enhancing their presentation skills and enriching their knowledge in educational video production.

According to Anthony, video production is fun and simple but in teachers’ perception, video shooting is not. Some teachers would have an unrealistic expectation that they could shoot the video in one take, which gives them unnecessary pressure. Anthony suggested that teachers could divide the shooting in shorter segments and use editing to make a seamless video. In the meantime, retaking a shot is very common even for a veteran actor. Hence, teachers should neither feel embarrassed nor uncomfortable about retaking. A tip for teachers is that they could consider taking two or even more shots for the same segments, and select the best one after viewing.
After the psychological readiness, Anthony shared the tips on other areas with the participants and the salient points are as follows:
Costume and make-up: The choice of clothes and make-up should go with the theme of teaching topic. For example, a chef uniform would be a good choice for shooting a food preparation class. A simple make-up could help project a sharp image. Teachers should also avoid clothes which the colour is very close to the background for stand out effect.
Speech and tone: Lively wordings in vivid tone are always welcomed by the young audience. Colloquial expression is preferred in Cantonese and English. Overuse of passive voice in English dialogue may make the educational video sound too formal.
Facial expression and body language: Apart from the facial expression and body language, one thing teachers may forget is the magnifying effect of the camera lens. For example, a spot of stain could be eye-catching and a shake of hand could become a wave through the lens. Hence, teachers have to be aware of their clothing, their quirks and range of movement. If you would like to emphasise a point, a slight nod of head will do.
Practice makes perfect, and there is no exception for video shooting. Anthony encouraged our teachers, “Recording yourself is a good exercise for identifying your quirks and pinpointing areas you need to improve on. Enjoy what you're doing. Shooting for educational video is fun, and meaningful to your teaching.”
Dear teachers, are you ready for lecture capture?
