The range of capability of academic accomplishment of students is growing wide due to the enhanced variety
of college entrance processes and increased number of foreign students. Therefore, there are various trials of assisting students’
academic performances. Tutoring is one of the most common methods of assisting students for academic performances,
yet the number of studies to verify the effectiveness of tutoring program is limited. The current study was designed to
investigate the effectiveness of intensive tutoring program and house tutoring program, which were provided to freshmen students
of the College of Science, the College of Engineering, the College of Life and Biotechnology. The participants of current
study were students who received a grade under D+ in their math course. Among them, 30 students were enlisted to the
intensive tutoring program, 13 students were enlisted to the house tutoring program, and 30 students did not receive any kind of tutoring program. The current research provided the tutoring program for a semester, and then compared the academic performance
of students in intense tutoring group, the house tutoring group and the control group. In addition, it compared the
percentage of students who received a grade above B+ in the Fall semester of 2015 to the students in the three different
groups. The result revealed that the academic performance of intensive tutoring group significantly increased after participating
in the program, while the performance of the house tutoring group and the control group did not. In addition, 52% in the
intensive tutoring group, 13% in the house tutoring group, and only 2% in the control group received a grade above B+ in Fall
semester of 2015. The results suggest that intensive tutoring, which is organized, systematic, and has low tutor to tutee ratio, is
effective in improving the academic performance of college students. The house tutoring program is also found to be effective,
but the size of the effect is relatively small compared to the intensive tutoring program. The implication for the research
and the limitations are discussed further.
