In　education,　learning　concentration　is　closely　related　to　the　quality　of　learning,　and　teachers　can　adjust　their　teaching　methods　accordingly　to　improve　the　learning　outcomes　of　students.　Particularly　in　head-mounted　virtual　reality　interactions,　current　methods　for　assessing　learning　concentration　cannot　be　fully　applied　to　new　interactive　environments　because　immersion　shaping　and　cognitive　formation　differ　from　the　conventional　education.　Therefore,　in　this　study,　a　learning　concentration　assessment　method　is　proposed　to　measure　the　learning　concentration　of　students　in　head-mounted　virtual　interaction,　using　the　expression　score,　visual　focus　rate,　and　task　mastery　as　evaluation　indicators.　In　addition,　the　weights　of　the　evaluation　indicators　can　be　configured　to　be　included　in　the　calculation　of　learning　concentration　depending　on　the　characteristics　of　different　types　of　courses.　The　results　of　a　usability　evaluation　indicate　that　the　learning　concentration　of　students　can　be　effectively　evaluated　using　the　proposed　method.　By　developing　and　implementing　strategies　for　optimizing　learning　effects,　the　learning　concentration　and　assessment　scores　of　students　increased　by　18%　and　15.39%,　respectively.
