This quantitative methods study explored the knowledge, attitudes and practices of PK-5 teachers on the use of technology applications in the classroom. The Texas State Board of Education has set in place standards for technology applications that require the use of technology applications across all grades. Likewise, the American Academy of Pediatrics (AAP) published new guidelines on the use of technology by children. However, it is the responsibility of teachers to implement and embed these standards, while also paying attention to the recommendations of the AAP. I developed a survey that provided demographic information, and included 12 items to measure the knowledge, attitudes and practices of teachers of technology applications in the classroom. Participants included 251 PK-5 teachers from three different districts in a South Texas region. Multiple regressions were conducted for each of the constructs produced by a factor analysis. Knowledge and attitudes presented no statistically significant results from individual teacher characteristics, but there were statistically significant differences on attitudes by districts. The regression analysis for practice reported a statistically significant difference between teachers that held a master's degree and those who did not. I conclude that technology applications implementation in the PK-5 classrooms is still developing and evolving, but there is still no consistency across districts, and further research in this matter is still needed.
