Independent Study Proves Effectiveness of Rosetta Stone Software
According to an independent study conducted by Roumen Vesselinov, Ph.D., a visiting professor at Queens College City University in New York, after 55 hours of study with Rosetta Stone software, students will significantly improve their Spanish language skills and 56 to 72 percent of students will increase their oral proficiency by at least one level as measured with the ACTFL OPIc test.
Eighty to 90 percent of participants evaluated Rosetta Stone Spanish software as “extremely favorably” and agreed that the software was easy to use, very helpful, enjoyable and very satisfactory, and that they will recommend this software to others.
Study participants were randomly selected from respondents to an advertisement and could choose whether to study Spanish in a home environment or at a Rosetta Stone facility. Participants were instructed to use only Rosetta Stone software during the study. No other tools or materials were used by participants as far as we know.
