Annotated bibliography and critical preface

The author wrote a critical preface before the annotated bibliography which explained why the argument covered by the sources was significant to other people and also summed up the research in the annotated bibliography. The argument seems to be about whether or not art programs should be in schools. In the Critical preface the author lists some questions  about this subject and then tries to cover them in the sources gathered. The sources in the bibliography seem to center mostly around the pros of having art classes in schools. Given this, the author will have a lot of information to support that side of the argument of having art programs in school.

There are a couple problems that I notice. The first one is that the author does not include some important information in the critical preface. This information missing is the plan for future research and how the author will go about doing it. The second problem is that the author does not provide enough sources to support the other side of the argument on art programs in school. She has plenty of references on the good side of it, but not the bad side/
