The three pie charts illustrate the distribution of students’ participation in different types of courses—face-to-face, correspondence, mixed media, and online—in the years 1984, 1994, and 2004.
In 1984, the majority of students, 67%, attended face-to-face courses. Correspondence courses were the second most popular, with 20% of students enrolled. Mixed media courses accounted for 13%, while online courses were not yet a category.
By 1994, face-to-face courses remained the most popular but saw a decline to 54%. Correspondence courses held steady at 20%, and mixed media courses slightly increased to 15%. Online courses emerged as a new category, comprising 11% of student participation.
In 2004, face-to-face courses continued to decline, representing 40% of students. Mixed media courses saw a significant rise to 35%, becoming the second most prevalent type. Correspondence courses decreased to 15%, and online courses slightly decreased to 10%.
Overall, the data indicates a trend of decreasing face-to-face course participation and increasing use of mixed media courses over the two decades. Correspondence courses remained relatively stable initially but eventually declined, while online courses emerged and slightly fluctuated.
