Remedial education is defined as the programmes provided by education institutions to help unprepared students reinforce their basic skills. Recently, the increased access to higher education has caused a higher dropout rate of science and engineering major students, especially when they are academically underprepared for college-level study. Thus, this study proposes a new type of remedial programme which helps students majoring in science-related foundation courses for their follow-up learning. Literature about the effectiveness of remedial education is inconsistent and how this new remedial education program affects students' learning achievement is not well understood. Thus, this study aims to examine how remedial courses change students' attitudes and improve learning performance. Our findings indicate that: (1) remedial education significantly enhances the students' academic achievement; (2) remedial education quality affects students' course satisfaction and achievements through self-efficacy. We hope these findings bring more insights into research and practice.
