Hi Emily, Curriculum and Teaching Dialogue is the official journal of the American Association for Teaching & Curriculum (http://aatchome.org/). It is published annually to coincide with the AATC conference - Volume 23 will be published in October 2021. Each volume of the journal consists of two issues containing articles related to research on teaching and/or curriculum. Articles are not limited to higher education, CTD has published articles on aspects of early childhood, elementary, secondary, post-secondary, and adult education. Articles are also not limited to American education. Currently, CTD's acceptance rate is just under 40%. There are no processing charges and the journal is published in hard copy only and not open access. All articles go through a rigorous, blinded, peer-review process.
