Primary Outcomes (end points)
The primary outcomes are:
• Grade in Maths
• Proficiency with computer (How comfortable do you feel using a computer, including the internet? How comfortable do you feel using the internet on a computer? How comfortable do you feel using the internet on a cell phone? How comfortable do you feel sending an email? How comfortable do you feel talking on Skype?)
• Oral proficiency in English (understanding a native speaker, conversation, vocabulary range, and spoken fluency)
• Cross-cultural communication (How comfortable would you be talking to somebody from another country? How much would you worry about what to say if you were talking to someone from another country?)
These outcomes will be looked at only if there is sufficient variation in the data.
I will use a difference-in-differences analysis. Multiple hypothesis testing will be done by creating indexes, as well as with the the Sharpened False Discovery Rate (FDR) adjusted q-values (Anderson, 2008).
The research plan includes subgroup analyses by:
• high- or low-ability students
