Recently Google Scholar has introduced a new journal metric as an alternative to the impact factor. It’s called the H5 index. Basically it is equivalent to the Hirsch index, but calculated for a journal rather than an individual author, over a five year period. An H5 of 10, for example, means that during the past five years a journal has published 10 articles which were each cited at least 10 times. (image credit)
Google Scholar is now offering lists of the top 20 journals in various subject categories by H5-Index numbers. Here are the links to various categories in education:
