You don't see AP courses as part of the academic curriculum.
Until the middle of the 20th century many schools simply taught their students facts and figures. You memorized and regurgitated information. Indeed I can remember being taught this way at Rosyln School and Westmount High School back in the '50s and '60s. That's just the way you were taught back then. All of your academic work was focused on what you could expect to be tested on in your final year end exams. This all led inexorably to a forbidding set of examinations known as the Junior Matriculation. If you did well on that set of examinations administered at the end of Grade 11, you went off to university for more of the same.
Progressive schools by definition are schools which espouse the ideals and ideas of landmark educators and thinkers such as John Dewey and Francis Parker. At the beginning of the 20th century they were considered visionary by some, radical by others. The progressive curriculum was more varied and experiential. Students just didn't sit there passively listening to a teacher lecture about the material. They actually were encouraged to learn by discovery through a variety of hands-on activities. Teachers no longer had to get through a plethora of outdated materials simply to be able to say that they had 'covered' the required coursework. There was time to stop and explore. Have discussions. Stimulate analysis. Encourage critical thinking.
Naturally there was no room for the rigid, deadline-studded curriculum of math and English leading to an intense last-minute binge of test-preparation in your junior and senior year for the AP exams which take place in May of your senior year.
As you can imagine, teaching to the test became a critical part of every teacher's daily routine. If you didn't get good test results, you weren't a good teacher. And, worse, the students were not learning.
Progressive schools have managed to get wonderful results by teaching their students in all sorts of ways. Passive learning went out. Active learning was the norm. Indeed learning takes place across the curriculum and throughout every aspect of the school community. Learning is not compartmentalized or relegated to a classroom.
You also won't see academic tracks with names such as 'advanced' or regular. Progressive schools teach to all levels of attainment. They respect each student's diversity. They don't see those differences as strengths or weaknesses. This approach in turn leads to a greater respect for each individual in the school community.
Students don't receive traditional report cards.
Starting with the earliest years in Montessori, Waldorf and Reggio Emilia schools, a child's progress is charted by accomplishments, not by test results. You will not see a traditional report card studded with As and Bs if your child attends a progressive school. You will receive a written assessment of your child's achievements, thoughtfully written by your child's teacher.
Assessments and evaluations of your child's work are discussed rather than being issued from on high. It is part of the collaborative process which is a hallmark of progressive education.
The overall approach is student-centered, not test-centered.
When you visit a progressive school, you will see evidence of this student-centered approach all about you. You will have to experience it for yourself to understand all the implications for your child. We always thought of our children as sponges. It sounds a bit prosaic, but children really do learn by absorbing everything around them. When you send your child off to a progressive school, you can be assured that she will experience everything. Ideas, tasks, interactions and all the other aspects of a school community will be explored, analyzed and experienced from every possible angle.
The end product of a progressive education ideally is a student who can think and who can cope with everything life will put on her plate. That's a good thing in this dynamic 21st century world in which she will have to make her way.
