Although I don't recall seeing this particular film during my grade-school years, its dry, by-the-numbers style is reminiscent of the immediate post-WWII-era of multi-media enhancement to the curriculum. The films we watched were generally shown in the school's auditorium/gym. We'd leave the classroom row-by-row and walk single-file along a hushed hallway. No talking was allowed, of course.
