Final answer:
The Spacing Effect posits that intersession intervals of 20 to 30 minutes can enhance memory retention. The best intervals vary among individuals, and study habits reveal that students have differing needs. Studying in a distraction-free environment is also important for reducing interference and improving retention.
Step-by-step explanation:
The Spacing Effect suggests that an optimal amount of intersession interval (the time between study sessions) and retention interval (the time between the last study session and a test) can greatly enhance memory and learning. Students who study material in shorter, spaced-out sessions tend to retain the information better than those who cram all at once. For instance, breaking down study material into 20 to 30 minute chunks and spreading them out over a period of time can be more effective than studying for prolonged periods in a single session.
Interference can be minimized by studying in a quiet environment, free from distractions. This approach, along with moderate stress as suggested by Hupbach and Fieman (2012), can improve both immediate and delayed retrieval of information, which is crucial for educational success.
Furthermore, looking at study habits, the data indicates that there is a wide range in the time spent studying by different students. While 30 percent of students study seven or fewer hours per week, the majority study more. This highlights the variability in study needs and habits among students. Therefore, the best intersession interval and retention interval may vary from student to student.
