He also noted that these academic benefits were most significant in at-risk student populations. According to Rockman, a majority of teachers in laptop schools reported an increase in both cooperative learning and project-based instruction. Other research has not supported the educational benefits of laptop use. Also, Fisher and Stolarchuk reported a more positive relationship between laptops and student attitudes than between laptops and academic achievement. It remains to be seen what additional research will reveal about the long-term impact of laptops on student achievement and outcomes.
Critics point out the possibilities of theft, vandalism, and accidental damage.
However, despite the creative educational possibilities of laptops and promise of equitable access for all students, added costs in the form of hardware, network costs, technical support considerations, and faculty training remain the greatest obstacles. Despite these issues, many educators hoping to bring the benefits of educational technology to more students continue to look for creative ways to overcome these obstacles. The future of mobile computing in K-12 education is still uncertain. Laptops may never become as common in classrooms as hand-held calculators. Solutions for issues of cost, technical support needs, security, and equitable access are challenging for many schools.
