This experimental research reported in this work investigated if blended learning using a virtual learning environment improved students’ understanding of acid–base chemistry. The sample was drawn from Grade 8 students and compared the performance of students taught using formal learning and blended learning approaches. A total of 53 students from two different classes, were conveniently assigned to experimental (N = 22) and control (N = 31) groups. Data comprised pre- and post-tests of conceptual understanding, focus group interviews, examination of digital postings, student-written responses, and teacher planning diaries. Statistically significant differences were seen in the academic performance of the experimental group. The findings thus may suggest the use of a blended learning environment improves student understanding when learning acids and bases compared to the control group.MultidisciplinaryArticleSCOPUS10.1007/s43545-022-00447-z2-s2.0-8521097691826629283
