We receive several new typescripts a day. 我们一天收到几份打出的文稿。
The researcher has taken part in their lesson-evaluating activities for 9 times, and recorded the entire process with a voice recorder or a digital camera to collect information. In analysis of the typescripts, the researcher understands how they evaluate lessons. 我随机参加了9次评课活动,并用录音笔或数码相机进行了全程录音(像),以收集资料,通过对文本的分析了解老师们是如何评课的。
