What is an effective means to educate non-academic colleagues of the importance and time needed for Adjunct Lecturing research? My situation is, I am an Adjunct Lecturer (Physics); however, to support myself, I work full-time as a high school teacher.  Essentially, the situation is that an Adjunct Lecturer is working amongst non-academic colleagues, who unfortunately see the research as nothing more than a 'hobby'.

What is an effective means of helping these non-academic colleagues comprehend the importance and time-needed for the research involved with being an Adjunct Lecturer?
As @NateEldredge mentioned, technically research is probably not part of the duties of an Adjunct Lecturer.

That being said, you could explain that as an adjunct it is natural for you to develop your CV further so that you may be considered for teaching higher-level courses, increase in rank, service on interesting committees, etc., in which case research will be important.
