The lessons are balanced and offer both sides. For example, each lesson includes four primary sources, two Arab and two Israeli.
The first lesson examines the development of Zionism and Arab nationalism. Documents about the development of Zionism include an excerpt from Theodor Herzl, and one from the First Zionist Congress in 1897. The lesson examines the development of Arab nationalism with excerpts from the writing of Sati' Al-Hursi and another from the First Arab Congress in 1913.
The second lesson looks at the promises made to both Arabs and Jews after World War I. The first two primary sources focus on the promise made to the Arabs with an excerpt from the Hussein-McMahon correspondence in 1915, and the Sykes-Picot Agreement. Promises made to the Jews include the Balfour Declaration and the Feisal-Weizmann Agreement in 1919.
