I've had a love-hate relationship with Van Manen; after an initial awestruck fascination stage I passed through disgust, apathy, and more recently, acceptance stages.
If one wants to do phenomenological education research, this is certainly the "how to"/reference guide. My qualms have been about a perceived lack of rigor (for Van Manen is very easy to read and understand, almost "too easy" for grad school, it seemed at first...), however over time I have come to appreciate that dense verbiage does not equate rigor, and Van Manen's research is grounded in a solid foundation of post-Husserlian phenomenology from mainly Heideggerian & Gadamer-iam perspectives (with a touch of Derrida and Merleau-Pont). - However Van Manen's bibliography is not exhaustive by any means, it's only 8 pages, and it doesn't touch on many important writers such as most women phenomenologists, i.e. De Beauvoir or Arendt) - i.e. this work is not critical in the sense that it does not even acknowledge feminist, race-based, justice-based perspective, or ethics (per Levinas). It does tangentially mention ethics (as a consideration of the research process), but does not attend to ethics as *part of* the structure of lived experience (for example, of lived relation to the other).
Good basic foundation/overview of phenomenological education research methods, but not very critical or in-depth.
