An engineer by bachelors training, Manu taught mathematics to 12th graders in Singapore before getting his doctorate in instructional technology and media from Teachers College Columbia University, where he also completed a Master of Science in Applied Statistics. Manu conceptualized the notion of productive failure to explore the hidden efficacies in the seemingly failed effort of small groups solving complex problems collaboratively in an online environment. Over the past six years, Manu has done extensive work on productive failure in mathematics classrooms in Singapore, during which time, his research has also attracted interest and funding both locally and internationally.
