Higher Education research journals
There are a lot of journals which publish research and case studies on teaching and learning in Higher Education, either in general or specific to a particular discipline.
The TLDU web links include a list of Higher Education journals including some subject-specific ones.
You might like to consider submitting to Practice and Evidence of the Scholarship of Teaching and Learning in Higher Education (PESTLHE). This online journal offers an opportunity for those involved in University learning and teaching to disseminate their practice. It aims to publish accounts of scholarly practice that report on small-scale practitioner research and case studies of practice that involve reflection, critique, implications for future practice and are informed by relevant literature, with a focus on enhancement of student learning. This publication thus offers a forum to develop and share scholarly informed practice in Higher Education through either works in progress or more detailed accounts of scholarly practice. The journal is published twice a year (April and October).
