PurposeIn response to coronavirus disease 2019, California State University Long Beach (CSULB) announced mandatory online course conversions on March 12, 2020. The College of Business designed a Student Online Learning Experience Survey to explore learners' experience, needs, expectations and challenges in the online learning environment.Design/methodology/approachThe time-sensitive survey questions were administered using Qualtrics with Institutional Review Board approval. The authors used 5-point Likert scales to rate students' experience and satisfaction and performed statistical analysis. They assessed students' written comments to further corroborate statistical findings.FindingsThe results identify students' satisfaction are highly correlated to content coverage and interaction of online learning technologies. A combination of BeachBoard, Zoom, e-mails and publisher's website is valued most by the learners. Project-based experiential design is ranked #1 by graduate students. Noticeably, the upward trend of satisfaction with online modality from sophomore to senior is probably attributable to learners' maturity and number of years studied at CSU system. Overall, students generally dislike proctoring devices due to concerns of privacy, inequalities, mental stress, etc.Practical implicationsThe evidence-based results offer innovative pedagogical recommendations for business education in higher education.Originality/valueWhile prior studies examine student perceptions and satisfaction within the online education system, the study aims to deeply investigate the students' experience after a large-scale two-week institutional emergency course conversion mandate. This study systematically reviews students' experience with four aspects of online learning: (1) the adequacy of instructional designs; (2) the effectiveness of technology; (3) the appropriateness of the online learning material and (4) the integrity of online assessment and testing tools.
