就在去年，我正在班里组织研讨会，突然有人敲教室门。

Just last year, I was conducting a workshop when someone knocked at the classroom door.

必须推开教室门，在这一片静谧中走进教室。

I had no open the door and enter, in the midst of that perfect silence.

“翻到同一页”（[文章]作者的原话）似乎跟打开教室门是有点不一样的。

“Getting on the same page” ([article] author's words) seems a bit at odds with opening up class rooms.

有效校本教研必须以校本视野为立足点，这意味着，教师向同行“打开教室门”，并与外部研究者“若即若离”。

Effective school-based research must adhere to school-based horizon, which means the teacher opens the classroom door to his peers and keeps experts at an arm's length.
