1) The first study compared the effects of books with audiotapes, web-based instruction, and home robot-assisted learning on children's learning, concentration, interest, and academic achievement. The results showed that home robots were more effective than other media. 2) The second study examined student attitudes toward technology based on their learning styles. Students with a "converging" style had the most favorable views, while "diverging" students had the least favorable views. The study aimed to understand the relationship between attitudes and learning styles.
