The pie charts illustrate the distribution of students pursuing different types of courses over three years: 1984, 1994, and 2004.
Overall, face-to-face courses consistently accounted for the lion’s share of students, but their popularity fell over the years. Conversely, mixed media courses experienced an ascending pattern, while the figure for correspondence courses remained relatively steady. Notably, online courses were non-existent in 1984, emerging as an option in 1994 and maintained a tiny minority.
In terms of face-to-face courses, which were primarily registered by learners, they made up just over two-thirds of the total. In the next two periods, this rate had declined substantially to 54% and 40%, in 1994 and 2004, but remained the dominant type. In contrast, mixed media courses were recorded as the smallest proportion enrolled in by students. This figure had gone up gradually to 15% in 1994 and reached a peak at 35% by the last period, becoming the second-largest compared to all courses.
On the other hand, correspondence courses exhibited no changes over the first ten years, starting from 1984, constituting exactly a fifth of the students’ numbers. Moreover, online courses were first added in 1994 to diverse students’ options despite their rarity. This figure attracted only a small portion of the total, occupying just over 10% and relatively retained that level to the end.
