"The essence of teaching is to make learning contagious, to have one idea spark another." The maxim that few would disagree with is that teaching - be it lecturing, tutoring or guiding - needs to be imbued with the fire of passion, if those we teach are to be 'infected' or inspired to learn and to continue learning in ways that go beyond impersonal memorization. It would be easy, of course, to dredge out more similar maxims than to think through how precisely one could go about 'infecting' learners in positive ways. How, indeed, does one 'teach with fire'? What are the required tools, attributes and strategies? These constitute the focus of TCX33.
