Congressional Insights

Facilitator: E. Bergfeld, ASAS

Time: 2:00 PM – 5:00 PM

Description: The Congressional Insights program is a novel, state-of-the-art, interactive computer model de-signed to simulate a two-year term of office in Congress. This computer simulation and educa-tional tool introduces participants to the legislative and political process on Capitol Hill. Itillustrates why politicians must (or should) make some of the decisions they do.

The program will introduce you to the pressures faced by members of Congress, show you thedemands placed on their time, help you to understand that legislators are public officials whoseactions are open to public scrutiny, and provide you with a better understanding of the role ofelected officials and their staffs.

Participants are actively involved in this program. It focuses on policy and political issues andeffectively demonstrates some of the tough decisions faced by elected officials.

Congressional Insights

Facilitator: E. Bergfeld, ASAS

Room: 303B

Sponsor: ASAS Board of Directors

Time: 2:00 PM – 5:00 PM

Description: The Congressional Insights program is a novel, state-of-the-art, interactive computer model de-signed to simulate a two-year term of office in Congress. This computer simulation and educa-tional tool introduces participants to the legislative and political process on Capitol Hill. Itillustrates why politicians must (or should) make some of the decisions they do.

The program will introduce you to the pressures faced by members of Congress, show you thedemands placed on their time, help you to understand that legislators are public officials whoseactions are open to public scrutiny, and provide you with a better understanding of the role ofelected officials and their staffs.

Participants are actively involved in this program. It focuses on policy and political issues andeffectively demonstrates some of the tough decisions faced by elected officials.

Congressional Insights

Facilitator: B. Glenn, FASS

Room: 303B

Sponsor: ASAS Board of Directors

Time: 9:00 AM – 12:00 PM

Description: The Congressional Insights program is a novel, state-of-the-art, interactive computer model de-signed to simulate a two-year term of office in Congress. This computer simulation and educa-tional tool introduces participants to the legislative and political process on Capitol Hill. Itillustrates why politicians must (or should) make some of the decisions they do.

The program will introduce you to the pressures faced by members of Congress, show you thedemands placed on their time, help you to understand that legislators are public officials whoseactions are open to public scrutiny, and provide you with a better understanding of the role ofelected officials and their staffs.

Participants are actively involved in this program. It focuses on policy and political issues andeffectively demonstrates some of the tough decisions faced by elected officials.
