q2 · i? · causal · r1

Descriptive analysis of application usage and performance logs during the 30-day experimental period for the 24 experimental-group students; the author used "new vocabulary learned per hour" as the productivity measure (M = 77.99, SD = 30.69).

"In analyzing computer application usage and performance during the 30 day experimental period, weekly hourly usage was (M = 3.21, SD = 1.49, Min = 1.10, Max = 7.57). Students learned 968.21 new vocabulary on average (SD = 498.76 Min = 95, Max = 2502)."

Discussion¶

Related Claims¶

• Female students used the application more and learned more vocabulary, while male students scored higher on performance rating and posttest — related
• Mean new vocabulary learned per hour declined as students increased difficulty level, so time spent was not the primary determinant of learning — related
