Irrespective of where you are teaching it, you will need to consider, as Maryam and Aryan, mentioned, some basic subjects / content:
• Theory of heritage /architectural conservation which covers issues of stabilisation, conservation, restoration and reconstruction. This is critical so that the students understand what actions/decisions to take and what implications their decisions may have. The key question is always to what state a place should be 'restored'. You may find a situation, for example where a war-ravaged spiritual site should not be restored, but stabilised as a ruin in order to act as a reminder of war and its impact (there are examples for this in the UK, France and Germany).
• Students need to have a firm grasp of which actions are ethical and which not, and who needs to be consulted in these decisions. These are fundamental aspects as your conservation/restoration action creates or recreates a physical manifestation in the form of a structure. This has implications on the community where the structure exists as no piece of heritage architecture exists in isolation.
• Basic architectural history, covering form, styles, essence etc etc. This obviously will need to be tailored to where you are teaching. If you are planning to teach this in Iraq, you will have different architectural histories to consider than, say in Europe or Nigeria.
• Building materials, buildings systems and technology. Again, this will be dependent on where you intend to teach the subject as there will be variations in local building traditions and technologies. If you are planning to teach this in Iraq, you will have different building traditions (and technologies) to consider than, say in the USA or Australia or India.
• An firm understanding of the threats posed to the architectural fabric, through environmental decay (climatological, biological, geological), human interference (civil unrest, war, terrorism) and natural disasters.
• Appropriate conservation action (practical). Even though your students are unlikely to carry out the physical conservation work themselves, they need to understand what is involved so that they can adequately specify what actions should be taken and then also, on a case by case basis, supervise the works.
• Building codes and standards and knowledge to what extent past construction techniques are acceptable even though they may no be compliant with modern codes
* Site visits, field visits, practical demonstrations. This part cannot be overemphasised. Students need to see with their own eyes the problems and the solutions. You need to look for both good and bad examples.
• Network and have conservation professionals speak to your class, dial them in via Skype, for example.
• Set problem-based assessments, simulating real life scenarios as closely as possible. Consider small-group based assessment that mimics real-life teams.
I would definitely talk about the Historic Urban Landscape approach (e.g. http://www.historicurbanlandscape.com and http://portal.unesco.org/en/ev.php-URL_ID=48857&URL_DO=DO_TOPIC&URL_SECTION=201.html ) and Heritage Impact Assessment (e.g. http://www.iccrom.org/heritage-impact-assessments/).
You might already have done all this, but presuming you will teach this at the university in your profile, it might also be interesting to see what for example Aga Kahn (e.g. http://www.akdn.org/our-agencies/aga-khan-trust-culture/aga-khan-historic-cities-programme/historic-cities-overview) is doing in your region, or what they offer in terms of education packages, as well as (regional / national centres of) unesco, icomos. etc. You could also have a look at other conservation master curricula, the ones I know are mostly in Europe, e.g. UCL (https://www.bartlett.ucl.ac.uk/heritage), Cottbus (https://www.b-tu.de/en/heritageconservation-ma/characteristics), IUAV Venice. But also maybe WHITRAP http://www.whitr-ap.org/index.php?classid=1459
Surely there are many others that might be better for what you are aiming for, these are just a few I'd use!
