The line graph illustrates the weekly number of hours spent on three different study methods — Internet, Library, and Lectures/Classes — over the course of two years, divided into four semesters.
Overall, the most significant trend is the sharp and consistent rise in internet usage throughout the period. In contrast, time spent attending lectures and classes decreases slightly by the end of the course, while library usage fluctuates but shows no clear upward or downward trend over time.
At the beginning of Year 1, students spent approximately 7 hours per week in lectures, making this the most time-consuming method. However, by the second semester of Year 2, this figure had fallen to just 5 hours per week, showing a steady decline. Similarly, library use, which started at 4 hours in the first semester, initially dropped to 3 hours before rising steeply to 8 hours during the first semester of Year 2. However, this increase was not sustained, as library hours fell again to 6 by the end of the period.
In contrast to these fluctuating patterns, internet usage exhibited a strong upward trajectory. Students began by spending only 3 hours per week using the internet in the first semester of Year 1. This figure rose gradually in the first year and then more dramatically in the second year, finishing at over 10 hours per week by the final semester.
In summary, while the internet became increasingly dominant as a study tool over the two-year period, the time devoted to lectures and classes gradually declined, and library usage saw notable fluctuations without a clear long-term trend.
