学习课程15.040的同学要参加2种互动练习，详细描述如下：
Students in 15.040 participate in two types of interactive exercises, as described here:

课上博弈
ONLINE GAMES

4次讲座中我们会在课上模拟博弈，课前要做好准备。准备包括阅读和完成1到2页的工作表，用不到20分钟的时间准备博弈。经过仔细思考的完整工作表将会得到满分（课上或课前把工作表交给助教）。
In four lectures, we will play a game in class that requires preparation before class. This will involve reading and completing a 1-2 page worksheet, taking no more than 20 minutes per game. Full participation credit will be given for a thoughtfully completed worksheet (handed in to TA at or before the beginning of class).

网上博弈
ONLINE GAMES

所有讲座过半前，学生要参加一个网上博弈。不需要做准备。多数博弈要5到15分钟来参与。参与博弈就可以得到满分。那些在所有博弈中表现超出标准的学生会得到附加分。在最后是博弈之后教授会发布评分标准和超出标准的学生名单。网上是博弈将会在第二天的讲座上会有简短的讨论。
Prior to about half of the lectures, students will play an online game. No preparation is required. Most games require about 5-15 minutes to play. Full participation credit will be given for playing the game. Bonus participation credit will be given to those whose performance across all the games exceeds an objective threshold. The professor will reveal the threshold and who exceeded it after the last game is played. The online games are designed to prompt discussion in class the following day.

网上博弈的分配
Logistics of Online Games

关于如何参加网上博弈的信息会在上课的时候给出。网上博弈是由范德比尔特大学的Mike Shor助教编写的，以下的总结描述也是由他提供的。更多的信息可以在GameTheory.net上找到。
Information about how to access the online games will be provided in class. The online games were written by Assistant Professor Mike Shor of Vanderbilt University, and the summary descriptions available below are courtesy of him. More information is available at GameTheory.net.

网上博弈在讲座当天下午5点开始开放，必须在下次讲座前的午夜参加。结果将会在课上公布。（请注意以下表格中赛局的编号不是连续的；它和GameTheory.net网站中的编号相同。）
Games will become available by 5:00 PM the day of the lecture in which they are announced and must be played by midnight the day prior to the next lecture. Results from the online games will be announced in lecture. (Note that the numbering of the games in the table below is not sequential; it corresponds to the game numbers on GameTheory.net.)
