Dr Perez Is a New Teacher Who Is Interested in Creating

Dr. Perez is a new teacher who is interested in creating the most conducive learning environment for her students. After great consideration, she has decided to ban the use of laptops for note-taking in her classroom. Instead, students are only allowed to take notes using pencil and paper. At the end of the semester, she assesses her students by examining their overall course grade [on a scale from 0 (lowest possible grade) to 100 (highest possible grade)] and their feelings toward the laptop policy [on a scale from 1 (unfavorable) to 7 (favorable)]. Finally, she compares her data with those of a colleague who does not restrict laptop use. Results reveal:
Student performance: t(251) = 5.18, p = .03, d = .46 (M_restricted = 79, M_unrestricted = 75)
Feelings toward policy: t(251) = 6.29, p = .02, d = .51 (M_restricted = 3.69, M_unrestricted = 5.87)
Please interpret these results to explain whether Dr. Perez's laptop policy helped to create a more conducive learning environment, noting specifically what her results reveal about each test variable.
