Orthodox see the Talmud as binding for Jewish life today. In orthodox synagogues men and women sit separately.
Reform doesn't see the Talmud as binding for the Jewish life today, rather emphasizes universal Jewish values. Reform synagogues incorporate music into Sabbath worship, tend to use the vernacular language, English or German instead of Hebrew, in worship, and families sit together in worship.
Conservatives occupies a middle ground between reform and orthodox. They see Talmud as binding for Jewish life today, but engages in more modern methods of interpretation rather than relying solely on rabbinic tradition for understanding their scriptures.
