Experimental Design
Before the semester started, SNU took applications from freshmen for the LnL program. Out of the 885 applicants, 235 students were randomly selected through a competitive rate of 3.6 to 1. The selection was done through a random drawing, ensuring a 50% gender ratio, and adjusted so that residents from the metropolitan area did not exceed 40%. Additionally, applicants were selected in proportion to the number of applicants from each college, with a minimum number of entrants set for each college.
The 235 students who were selected to participate in the LnL Program were assigned to the treatment group. Out of the freshmen who applied but were not selected in the lottery, 470 students were randomly chosen using the same criteria as the treatment group and assigned to control group 1. Out of the freshmen who did not apply, 235 were randomly chosen using the same criteria as the treatment group and assigned to control group 2.
We plan to gather information on these 940 students through surveys and existing student records at SNU. In September 2023, a first survey will be conducted, followed by a second survey in February 2024. The survey consists of questions about school life, studying activities, extracurricular activities, career plans, teamwork and leadership, social interaction, personality, happiness and wellness, and various preferences and attitudes. With the cooperation of the SNU, we also plan to exploit students' academic records (major choice, grades, number and kind of course credits).
