Course Overview

Course Description:

This course is an advanced, fast-paced, highly rigorous elective for motivated students who are looking for a challenging social studies curriculum. It is designed to prepare students for the International Baccalaureate Organization’s (IBO) final assessment in social studies. The IBO curriculum determines the course outline and scope. This course is the first of a two-course IB history sequence (see the syllabus or program of studies for the second course, IB History of the Americas HL). The student will study the global history of the 20th century, focusing on the causes and effects of war, the rise and rule of single-party states, and the Cold War. In addition, the student will be required to undertake an in-depth study of a historical subject.

Course Requirements:

Students are required to complete the IB Internal Assessment (a research paper) as well as written examinations throughout the course. 



At the end of the marking period, the teacher will calculate students’ grades from tests, daily quizzes, specific assignments, etc. Letter grades will be assigned by the scale below.

Assignments are weighted. Tests, Quizzes, and other Assessments are worth .7. Homework and classwork are worth .3.

Student scores that result in .05 or higher should be rounded up. The following percentage scale applies.

100 - 91.5 = A

91.4 - 89.5 = A-

89.4 - 87.5 = B+

87.4 - 81.5 = B

81.4 - 79.5 = B-

79.4 - 77.5 = C+

77.4 - 71.5 = C

71.4 - 69.5 = C-

69.4 - 67.5 = D+

67.4 - 61.5 = D

61.4 - 59.5 = D-

59.4 - 0 = E

Grades will be rounded up only to the tenth place during this calculation. Students will only earn a passing grade for a marking period if they achieve at or above 59.45%, which rounds to 59.5%.


The final semester grade is based on a composite of two nine-weeks’ grades and the final examination/culminating assessment/project. Each nine weeks is worth approximately 40%, and the semester exam/project or District Culminating Activity assessment is worth approximately 20%.
