A commonly used text is Scott Gilbert's for which there is a WEB site. Please check the following URL's to get a flavor of what people consider to be embryology today. This is from the center for in vivo microscopy at the Duke Medical Center. It has some wonderful images of magnetic resonance microscopy of embryos. This site has wonderful diagrams and a list of useful links to other embryo resources.
Lecture tends to go the same way.
Medical schools generally view embryology as a way to introduce birth defects and how one goes about treating them. Cell and Molecular Biology courses deal with the gene regulation aspects of the topic. Most textbooks opt for molecular with some comparative anatomical material thrown in. Also Cogito Films has some wonderful videos that talk about various model organisms that have significant embryo importance. I trust this helps.
