Site versus Dashboard
Moodle contains two types of pages that can be used for the home page:
Site pages: This is a home page that is identical for all users. Well, sort of: its structure is static, whereas its content is likely to change depending on the user who is logged in. For example, every Site page might contain a block that displays the courses a user is enrolled into. This page is also known as Site home.
Dashboard: This personal home page can be customized for each user. For legacy reasons, this top-level page is often referred to as My Moodle or My home.
By default, authenticated users will see Dashboard as their home page. You can change this by navigating to Appearance | Navigation, where you have the option to specify Default home page for users. The options are Site, Dashboard (default), and User preference. If latter is chosen, the user can make this choice by going to Front page settings | Make this my default home page in the Administration block.
