The International Baccalaureate Program is one example of a fast-growing reform curriculum that focuses on critical thinking and purports to infuse an international outlook into all subjects. Research supports the conclusion that the IB curriculum introduces rigor and international mindedness in the classroom.
An Oxford University study examined case studies on the implementation of IB at several schools in the United States. The study found that as a result of IB program, schools were able to raise academic standards and change perceptions towards academic achievement, increase diversity within the school, bring international perspectives to the classroom, raise awareness around intercultural understanding, and improve the reputation of the school in the community (International Baccalaureate Organization, 2007).
The College of William and Mary also studied the impact of the IB program by analyzing it as an advanced academic option, comparing the curricular goals of the IB program to 21 recommended practices for gifted and general education. The researcher, Hutchinson, found that the IB curricular goals and the 21 recommended practices aligned with one another. IB teachers implement a variety of instructional strategies with high levels of instructional clarity and complexity and high expectations for student learning in and out of class (International Baccalaureate Organization, 2007).
One of the most extensive studies on the effectiveness of the IB program was conducted by William Kolb, director of admissions for the University of Florida. The University of Florida enrolls more IB diploma holders than any other institution in the world, in large part because of a state policy that provides full scholarships for IB diploma holders. Kolb analyzed data for the university’s 1996 freshmen class and found that IB students were better prepared for the shock of college academic demands and suffered less of a drop in grade point average in their first year of college compared to their high school performance level. The IB students on average had a GPA decline of 3.8 to 3.3, while AP students dropped from 3.9 to 3.1, compared to regular college prep students who lost a whole grade point, from 3.6 to 2.6 (Kolb, 1996).
Panich’s 2001 research, “A study of the university performance of students with International Baccalaureate high school experience” matched 1998, 1999, and 2000 IB graduates attending the University of Florida with students entering with comparable SAT verbal and math scores. She compared three groups: students with no IB experience, students with IB experience and students with an IB diploma. Panich found that IB diploma students had the highest freshman GPA while IB non‐diploma students had the lowest. The difference between the IB diploma students’ GPA and the non‐IB and IB non‐diploma students’ GPAs were statistically significant in all but one year (Panich, 2001).
Additional studies looking at post‐secondary outcomes for IB students include Taylor and Porath’s “Reflections on the International Baccalaureate Program,” (Taylor & Porath, 2006). Based on a survey administered in the Spring of 2005 of IB graduates from two public high schools in British Columbia who graduated in the years 1996 or 2000, the researchers report that the graduates felt that the rich curriculum to which they were exposed and the critical thinking and time management skills that they developed were well worth the extra effort required to earn an IB diploma. Furthermore, they felt that the IB experience prepared them well for post-secondary studies.
“Preparing today's students for success and eventual leadership in the global economy is the single most important task facing U.S. education. If young Americans are to take on challenging global leadership roles in the future, they must possess a deep understanding and appreciation for other cultures, geography, history, and languages." - Stephanie Bell-Rose, President of the Goldman Sachs Foundation
