In many countries there are subject associations which give members access to journals and knowledge sharing events. We recommend that you join your subject association. In addition, there are specialist bodies which publish high quality research summaries addressing issues relevant to teachers.

For example, UNESCO produces Educational Practices Guides.  See for example:

Creative thinking: Nurturing creative thinking
Educational practices: Effective educational practices
How children learn: How children learn
New media: Using new media
Pre-school language: Promoting pre-school language
Safe and Welcoming Schools: Creating a safe and welcoming school
Speaking, listening and writing: Teaching speaking, listening and writing
