This study has developed an automated system for feedback in a mixed reality environment depends on providing result about task processing steps according to learner's responses. The quasi-experimental approach was used based on the experimental design with two groups Pre-test and post-test, a cognitive test and a skill performance observation card were used. The study sample consisted of (84) students from secondary school second grade, who were randomly distributed to two experimental groups, the results showed that there are significant differences Statistical significance between the averages of cognitive test scores and student performance observation card estimates for two experimental groups in favor of using the detailed feedback style in mixed reality environment in developing visual programming skills.
