The impact of flipped classrooms on student achievement in engineering education: A meta‐analysis of 10 years of research.

Background: The flipped classroom has become more widely used in engineering education. However, a systematic and quantitative assessment of its achievement outcomes has not been conducted to date. Purpose: To address this gap, we examined the findings from comparative articles published between 2008 and 2017 through a meta‐analysis to summarize the overall effects of the flipped classroom on student achievement in engineering education. Scope/Method: We searched and analyzed journal and conference publications on flipped classroom studies in engineering education in K‐12 and higher education contexts. Twenty‐nine comparative interventions were included in a meta‐analysis involving 2,590 students exposed to flipped classroom and 2,739 students exposed to traditional lectures. A content analysis was also conducted to determine how the flipped engineering classroom benefits student learning. Conclusions: The meta‐analysis comparing these 29 traditional—flipped interventions in relation to student achievement showed an overall significant effect in favor of the flipped classroom over traditional lecturing (Hedges' g = 0.289, 95% CI [0.165, 0.414], p < .001). A moderator analysis showed that the effect of the flipped classroom was further enhanced when instructors offered a brief review at the start of face‐to‐face classes. Our qualitative findings suggest that self‐paced learning and more problem‐solving activities were the two most frequently reported benefits that promoted student learning. Based on quantitative and qualitative support, several implications are identified for future practice, such as offering a brief in‐class review of preclass materials. Some recommendations for future research are also provided. [ABSTRACT FROM AUTHOR]
